Intelligent control efficient drive–capsule thyristors led the power revolution

Capsule thyristor is an advanced semiconductor switching device with the characteristics of small size, stable performance, and strong controllability. Compared with traditional semiconductor devices, capsule thyristor can still maintain stable performance in extreme environments such as high temperature and high pressure, which significantly improves the reliability and stability of the power system. The core strength of the capsule thyristor is its unique structure. It adopts a fully packaged structure and integrates a variety of components, such as diodes, thyristors, etc., which makes capsule thyristors have higher integration and lower resistance loss in circuit design.

Structural characteristics of the capsule thyristor tube

A capsule thyristor is a semiconductor device with a fully packaged structure that integrates diodes, thyristors, and other components. This structure makes the capsule thyristor have the characteristics of small size, compact structure, and easy installation. In addition, capsule thyristor has the advantages of fast response and high withstand voltage, which can cope with the impact of large currents in a short time and effectively avoid risks such as overheating and overvoltage.

In contrast, traditional thyristors typically have a plug-in or surface-mount structure, which is complex to install and susceptible to environmental factors. In addition, thyristors with plug-in or surface-mount structures require process operations such as welding during the manufacturing process, which is easy to introduce mechanical stress and thermal stress, affecting their performance and service life.

Performance performance of the capsule thyristor tube

1) High-temperature performance: The capsule thyristor adopts a fully encapsulated structure, which allows it to adapt to high-temperature environments. At high temperatures, the trigger and maintenance currents of the capsule thyristor are relatively stable and do not change significantly. At the same time, due to the high level of integration of internal components, the heat dissipation performance has also been optimized, which further improves the performance at high temperatures.

2) Fast Response: Capsule thyristors use advanced chip design and manufacturing processes with fast triggering and recovery times. In circuit design, the fast response time allows for smoother current changes and avoids interference with other components. At the same time, under dynamic load conditions, the capsule thyristor is also able to quickly adjust the current size to adapt to the change in load.

3) Low leakage current: The capsule thyristor adopts an advanced chip manufacturing process and structural design, which has a low leakage current. In circuit design, low leakage current can reduce unnecessary energy loss and heat loss and improve the efficiency and service life of the circuit.

4) High inrush current capacity: Capsule thyristors are designed with the influence of inrush current in mind and have a high inrush current capacity. In circuit design, the high surge current tolerance can enable the device to withstand the instantaneous large current impact that may occur in the circuit, which improves the stability and reliability of the circuit.

In contrast, traditional thyristors perform poorly in high-temperature environments and are prone to thermal runaway. The response speed is relatively slow, and it isn't easy to adapt to rapidly changing load conditions. The leakage current is large, which is easy to cause energy loss and heat loss. The inrush current tolerance is weak, which adversely affects the stability and reliability of the circuit.

Application flexibility of the capsule thyristor

As an advanced semiconductor device, capsule thyristor has a wide range of application prospects. In the field of power electronics, capsule thyristors can be applied to various circuit topologies, such as single-phase half-control bridges, three-phase half-control bridges, inverters, etc. At the same time, due to its high withstand voltage and high current, it can also be applied to high-voltage and high-power power systems.

In contrast, traditional thyristors are limited by factors such as structure and performance in application, and it isn't easy to meet the application requirements of different circuit topologies and power systems. At the same time, conventional thyristors also have limitations such as small current capacity and low withstand voltage capacity.

The properties and uses of boron carbide and its synthesis process

Boron carbide (graph a) is a kind of black crystal with metallic luster, commonly known as black diamond. It is a powdery product made from boric acid as the main raw material, adding carbonaceous materials such as petroleum coke, and smelting and crushing in high-temperature solid state. It is similar to diamond, cubic nitride Boron is also a superhard material.

Boron carbide is insoluble in water and natural solvents, and has strong chemical stability, which is immune to acid and alkali rust, and does not react with mostly all acid and alkali services. Boron carbide also has the following attributes: it has a big thermal neutron capture cross-section and solid neutron absorption ability, so it is called a neutron absorber; it has semiconductor homes, and so on.

Properties and uses of boron carbide

Boron carbide (B4C) is gray-black and is a very hard man-made material with a Mohs firmness of 9.3 and a microhardness of 5500 ~ 6700kg/mm2, 2nd only to ruby and cubic boron nitride. The crystal structure of boron carbide is hexagonal crystal. Density is 2.52g/cm3. The melting point is 2450°C. When the temperature is higher than 2800°C, it decomposes and volatilizes rapidly. Its linear expansion coefficient is 4.5×10-6/℃ (20~1000℃), its thermal conductivity is 121.42(100℃)W(m·K), 62.80(700℃)W/(m·K), and its resistivity It is 0.44(20℃)Ω·cm and 0.02(500℃)Ω·cm. Boron carbide is immune to acid and alkali deterioration and does not wet with a lot of liquified steels, and has extremely high chemical security.Boron carbide can stand up to the oxidation of air at 1000 ° C, yet it is quickly oxidized over 900 ° C in an oxidizing setting. Boron carbide powder has a really high grinding capacity, which is 50% more than that of silicon carbide and 1 to 2 times more than that of diamond. It is an excellent abrasive material and wear-resistant material.

The biggest use of boron carbide is as an abrasive and a raw material for making abrasive tools. It is fit for grinding, polishing, drilling and other processing of various carbide tools, molds, parts, components and gemstones. Using an appropriate amount of engine oil or water as lubricant, boron carbide can be made into abrasive and polishing pastes. Boron carbide can also be used as a raw material for manufacturing metal borides, boron alloys, boron steel, etc. Except for special needs, it can be used to manufacture boron carbide hot-pressed products for wear-resistant and high-temperature-resistant parts, such as nozzles, sealing rings, gyroscopes, petrochemical parts, and lightweight and high-strength parts in military engineering. Control rods of an atomic reactor.

Synthesis process of boron carbide

The industrial method of synthesizing boron carbide is to reduce boron anhydride with excess carbon. The principle is:

2B2O3+7C→B4C+6CO

The synthesis reaction can be carried out in a resistance furnace or an electric arc furnace. A better method is to prepare boron carbide by heating a mixture of boron anhydride and carbon in a resistance furnace below the decomposition temperature of boron carbide. The boron carbide synthesized by this method contains very little free carbon and sometimes some free boron. During melting and synthesis in an electric arc furnace, since the temperature of the arc is quite high, boron carbide begins to decompose into a carbon-rich phase and boron at 2200°C. Boron will volatilize from the reaction space at high temperatures, so that the final reaction product contains a large amount of free carbon, the quality is poor. However, at present, domestic large-scale industrial production of boron carbide mostly uses arc fusion synthesis.

Three raw materials are used: boric acid (mass fraction greater than 92%), artificial graphite (mass fraction of fixed carbon greater than 95%), and stone coke (mass fraction of fixed carbon greater than 85%). According to the reaction formula, the proportioning synthesis reaction formula is:

4H3BO3+7C=B4C+6CO+6H2O

Among them, artificial graphite and petroleum coke each account for 50%. Considering factors such as high-temperature volatilization and oxidation in arc melting, the added amount of boric acid should be 2% higher than the calculated value, and the added amount of artificial graphite and petroleum coke should be 3% to 4% higher than the calculated value. After the three weighed raw materials are uniformly mixed in a ball mill, reduction and carbonization reactions are carried out in a single-phase two-electrode electric arc furnace or a three-phase electric arc furnace. The temperature of arc melting is controlled at 1700~2300°C. During the smelting process, it is best to feed materials in batches to block the arc light and achieve closed-arc smelting. After the smelting is completed, the melt is placed on carbon black or carbon electrodes to cool, and then the large pieces are smashed into 50mm-sized pieces with a hammer. Then the pieces are sorted according to their cross-sectional shape, and the unqualified pieces that are over-cooked and raw are removed.

According to experience, the cross-section of raw fired blocks is white or gray; the cross-sections of over-fired blocks are like graphite flakes or porous fused bodies; any steel-like dense cross-sections or metallurgical coke stripe-like cross-sections or sand-like cross-sections are For qualified blocks, the mass fraction of boron carbide is between 94% and 97%, and the mass fraction of free carbon is less than 1.5%. Then the qualified block is soaked in hot water and steamed, and then washed with water to remove the boric acid, boric anhydride and carbon substances adhering to it. The washed and dried large pieces are then coarsely crushed and passed through a 2.362mm sieve. Further coarse grinding and fine grinding can be carried out in a rotary ball mill or a vibrating ball mill. The coarse grinding time is shorter and the fine grinding time is longer. The iron added into the material during the ball milling process can be removed by leaching with hot sulfuric acid at 80°C. The amount of sulfuric acid added is 30% of the material. Pickling iron removal is carried out in a pickling tank. Add materials first, then add acid, then add 60' of water, stir with leaf slurry, and add steam to heat at the same time to increase the reaction speed. After pickling and soaking for 12 hours, dilute with water, ventilate and stir. After another 12 hours of incubation, remove the acid and wash with water until neutral. Finally, the purified material is sorted into granular products of different particle sizes using sedimentation fractions and serial water washing fractions. The settling semicolon is to divide the fine abrasive into fine powder of W35~W40; the series water washing semicolon is to divide the coarse abrasive into coarse particles of W40~120. If the coarse particles are further classified, the screening method can be used to divide the No. 120 particles into coarse particles of No. 100, No. 80, No. 70, No. 60 and coarser grades.

(1-pickling tank shell; 2-acid-resistant tiles; 3-acid adding port; 4-feeding port; 5-steam inlet; 6-hot water inlet; 7-discharge port; 8-water outlet; 9-stirring device)

Product manufacturing

Due to the technical difficulty in manufacturing boron carbide special refractory products, industrial production has not yet been established. It is only manufactured in small quantities to meet the needs of some special occasions. At present, the manufacturing process of boron carbide products is not complete and mature. Products can be made by hot pressing firing method and normal temperature pressure firing method. Since the latter method is difficult to produce dense products, the former method is usually used. Hot pressing can be accomplished in a hot pressing furnace with a carbon tube heated under the protection of argon (Ar) gas. The heating speed is not strictly controlled, and it usually takes about 2 hours to reach the maximum temperature. The hot pressing temperature is 2050~2150℃, the hot pressing pressure is about 30MPa, and the maximum temperature is kept for 30 minutes. The final product has a density of 2.46~2.51g/cm3, a porosity of 0.4%~0.6%, a compressive strength of 2250MPa, and a flexural strength of 280MPa.

Which is the best way to backfill a bathroom

The backfilling of the bathroom is a crucial part of any renovation. Backfilling is an essential part of bathroom renovations. It serves many purposes, including protecting the pipeline and stopping leaks, improving the thermal insulation, etc. In selecting bathroom materials, you should consider a number of factors depending on your specific situation. For example, take into account the performance and cost of backfill material as well the environmental impact.

There are five types of backfills available on the market: ceramic backfills (common slag), carbon slag re-fills (carbon slag), overhead re-fills and foam cement re-fills. We are confused about the different types of backfills.

Backfilling with slag can be cheaper, but because it is heavy and difficult to work with, the slag will crack the floor slab easily. This could lead to leakage of water.

It is cheaper to use overhead backfill because you don't need as much material.

Since a few decades, foam cement backfilling has been popular. But does it come with any disadvantages?

For your information, here are five bathroom backfill materials with their advantages and disadvantages and some selection advice:

Building debris backfill

Advantages:

The advantages of slag backfill are its lower cost, ease of construction and certain thermal insulation properties.

Disadvantages:

Backfilling with construction waste will damage the waterproof layer and the pipeline due to its sharp edges.

Recommendation:

The problem has been solved. Do not recommend this method. The budget of the family is too small to use construction debris backfill. To protect the waterproofing of the ground, first use fine sand, then red bricks, to protect the pipeline. The backfill should be compacted in layers. Finally, mud-mortar to level the surface will provide good secondary drainage.

Carbon Dregs Backfill

Advantages:

Carbon slag as a backfill has many advantages, including its low cost, ease of construction, lightweight structure, good moisture absorption, and excellent moisture control.

Disadvantages:

Carbon dregs are not as stable, they can easily deform and fall off. They're also flimsy.

Recommendation:

In recent years, carbon slag has rarely been chosen as a backfill in bathrooms due to its negatives.

Ceramic Backfill

Advantages:

Ceramic backfill has many advantages including high strength, good insulation and corrosion resistance.

Disadvantages:

Before pouring in the ceramic, use lightweight bricks for layered partition. Divide the bathroom into several squares. Fill the squares with the ceramic, then place a reinforcing mesh with a diameter around one centimetre. Finally, level with cement mortar.

Suggestion: Look at your family's budget and take it into consideration.

Overhead Backfill

Advantages:

Backfilling with overhead backfill has many advantages, including its simplicity, stability, inability to deform and easy fall-off.

Disadvantages:

The labour cost of backfilling is higher because the construction cycle is longer. The sound of running water is louder when the bottom drain is located overhead.

It is important to carefully consider whether the disadvantages of the situation outweigh any advantages.

Foamed Cement Backfill

Advantages:

Foamed cement is an increasingly popular backfill. It is also safe and eco-friendly. The raw material for cement foaming agents, plant-based fat acid, is both safe and environmentally friendly.

Benefits include good heat conservation, light weight, high strength and corrosion resistance. The backfilling process is greatly accelerated and reduced in cost, as it can be filled seamlessly and with very little effort.

Foamed cement can be mixed with cement and used to fix the pipe. If not, the pipe will easily float.

Disadvantages:

It is best to find a builder that has worked with foam cement or look up construction tutorials.

Suggestion:

The majority of people backfill their bathrooms with foamed-cement. Its advantages are still quite obvious.

The five types of backfill for bathrooms all have advantages and disadvantages. In order to choose the right material for your bathroom backfill, you should consider several factors. You must always consider the environmental aspect when choosing bathroom backfill materials to ensure the decor of the bathroom is safe and sustainable.

Lithium Stearate Production Process :

Chemical synthesis method

Lithium stearate can be synthesized through a series chemcial reactions that combine stearate (stearate root) with lithium metal. In order to get the lithium metal reacting with the stearate, they are heated together in an organic solvant. After washing, separation and drying, the pure lithium-stearate product is obtained.

Following are the steps for synthesis.

(1) Lithium metal and stearate in organic solvents, such as ethanol heated stirring to fully react.

(2) The reaction solution must be cooled in order to precipitate lithium stearate.

Wash the crystal with water and remove any remaining lithium stearate.

(4) The dried crystals are used to make lithium stearate.

Chemical synthesis is characterized by a matured process, high efficiency in production and high purity of the product. However, organic solvents have an environmental impact and waste is generated during production.

Methode de fermentation biologique

In biological fermentation, microorganisms such as yeast are used in the medium to produce lithium. This method works on the principle that microorganisms produce stearic and react with metal ions, such as lithium, to create lithium stearate.

These are the steps that you will need to take in order to produce your product.

The microorganisms will be inoculated onto the medium that contains precursor substances for fermentation cultures;

(2) The filtrate is used to produce a solution of stearic acetic acid.

(3) Add metals (such as the lithium ions) into the solution with stearic to ensure that they fully react.

(4) The reaction product is separated and washed, then dried to give lithium stearate.

The benefits of biological fermentation include environmental protection, less waste discharge and a longer production process. However, the conditions for production are also higher.

Prospect Market of Lithium Stearate:

The application of lithium in personal care will continue to play a major role. It plays a vital role as a surfactant in soaps, cosmetics, body wash, and shampoos. As people's standards of living improve and the cosmetics sector continues to expand, lithium stearate demand will gradually rise.

Second, the use of lithium stearate for polymer synthesis has also increased. It can be used both as a donor and a participant in polymer chain formation. As polymer materials science continues to develop, the demand of lithium stearate increases.

Lithium stearate's application in agricultural, petrochemical, pharmaceutical and other fields is also growing. In the pharmaceutical sector, lithium stearate may be used as a carrier, excipient or drug stabilizer. In the agricultural field, lithium stearate is a carrier for fertilizer and a plant protector. In the field of petrochemistry, lithium isostearate may be used as an lubricant or release agent. In these areas, the demand for lithium will increase as technology advances.

But the outlook of the lithium stearate market is not without its own challenges. In order to produce lithium metal, it is necessary to use a more expensive production process. Aside from that, the applications of lithium is limited, with a concentration in agriculture, petrochemicals, polymer syntheses, personal care products and pharmaceuticals. To expand the scope of application and the demand for lithium stearate, it is important to continue to develop new applications and markets.

More than a hundred schools in the UK have been closed due to the risk of collapse

In the UK, more than 100 schools were closed because of the danger of collapse

In the UK, many schools use Autoclaved aerated cement (RAAC). This is a concrete material that is lighter.

In 2018, the roof of a school in southeast England collapsed. It was later discovered that RAAC had been used for the roof as well as the buildings. This raised safety concerns.

BBC reported that RAAC materials were widely used from the 1950s until the mid-1990s in areas such as roof panels, and had a lifespan of around 30 years.

According to reports, the risk of building collapse is not only present in schools, but also in hospitals, police station, courts and other public structures. RAAC material has been found.

The Royal Dengate Theatre at Northampton is temporarily closed after RAAC material was found.

According to NHS, RAAC has been detected in 27 hospital building.

The NHS chief has been asked for measures to be taken to prevent collapse.

BBC reported that since 2018 the British government has warned schools to be "fully ready" in case RAAC is found within public buildings.

The Independent reported Jonathan Slater a former senior education official, who said that Sunak, Prime Minister in 2021, approved budget reductions to build schools.

Nick Gibb is a senior official at the Department of Education. He said that the Department of Education asked for PS200m annually for school maintenance. Sunak was the former chancellor of exchequer and provided just PS50m a year.

The report also states that despite Sunak having promised to renovate at least 50 schools every year, in the main reconstruction plan of the government only four schools were renovated.

The British National Audit Office chief also criticized this crisis. He claimed that the Sunak government had adopted a "plaster-method" of building maintenance.

He believes the government's underinvestment has forced schools to close, and that families are now "paying the cost".

Paul Whitman is the secretary-general of National Association of Principals. He said parents and public will see any attempt by government to shift the blame from their own major mistakes as a "desperate attempt by the Government to divert its attention."

Whitman claimed that the classroom has become completely unusable. Whitman blamed the British Government for this. "No matter what you do to divert or distract, it won't work."

London Mayor Sadiq khan said that the government should be open and transparent. This will reassure parents, staff, children, and others.

BBC reported schools in the UK were pushing forward with inspections and assessments. Children who had been suspended because of school building issues will be temporarily housed, or they can learn online.
