What are the high temperature insulating materials? 6000 What are the high temperature resistant mat

1.The heat resistance class of the insulation material used in the windings of the motor (or transformer) is also known as the insulation class. The heat resistance of commonly used insulating materials for motor transformers is divided into seven grades: Y, A, E, B, F, H, C, etc. :

y, a, e, b, f, h, 180 and c, respectively.

2.Each insulation class has a corresponding limit permissible operating temperature (the maximum temperature of the motor or transformer windings). When the motor or transformer is running, the temperature of the hottest spot of the winding shall not exceed the provisions of Table 6-1, otherwise it will cause accelerated aging of the insulating material and shorten the life of the motor or transformer; If the temperature exceeds the permissible value by a lot, the insulation will be damaged, causing the motor or transformer to burn out.

In fact, there are usually three types of insulating materials: gas insulation, liquid insulation and solid insulation, because the gas insulation conditions are very harsh, and the liquid insulation operating conditions are too harsh, or the fixed insulating materials are much better. The most common ones are insulating sleeves. Insulating paper, laminates, erasers, plastics, paints, glass, ceramics, mica, etc.

Generally, paper, wood, and rubber materials are all insulating materials, which is common sense, so there are many derivatives.

There are seven heat resistance grades of insulating materials, from low to high, they are y a e b f h c

Grade Y is the lowest grade, and the allowable operating temperature of 90 degrees Celsius refers to the insulating structure composed of materials such as unimpregnated cotton yarn, silk and paper or their compositions.

The maximum allowable temperature of grade A is 105 degrees Celsius, which refers to the insulation structure composed of materials such as cotton yarn, silk and paper or their compositions in the transformer oil.

The maximum temperature of grade E is 120 degrees Celsius, which refers to the insulation structure composed of synthetic organic films, synthetic organic enamels and other materials.

Grade C is the highest grade, and the maximum allowable temperature can reach more than 180 degrees Celsius, which refers to the insulating structure composed of mica, glass fiber, and non-impregnated mica, ceramic, quartz and other materials or their compositions after resin bonding or impregnation, coating, and non-impregnated.

The maximum allowable temperature of grade B is 130 degrees, and the insulating structure composed of mica, glass fiber, asbestos, etc., coated with suitable resin, mica, glass fiber, asbestos, etc., and other inorganic materials, suitable organic materials or their compositions is used for the maximum allowable temperature of 130 degrees.

The maximum allowable temperature of H grade is 180 degrees, and the insulating structure composed of materials such as mica, glass fiber, asbestos and other materials or their compositions is bonded or impregnated with suitable resin (such as silicone resin).

PAEK, PEEK, PU, PAEEK should meet your requirements It is a bit expensive, and the temperature resistance is 240 degrees 390 degrees.

There are also C CSI composites, which are temperature resistant to more than 1600 degrees, lightweight, strong, and not very smooth, and more expensive.

Step 1: Define the range of high temperature, normal temperature usually refers to the temperature of the living environment of people in the natural climate, and the temperature value of high temperature is different in different industries. In the field of inorganic non-metals, Celsius.

Above 80 degrees is basically the critical value of "high temperature".

Step 2. According to this range, there are materials and classifications as follows: carbonates.

class of calcium carbonate.

Most typical; Silicates are calcium silicate.

magnesium silicate, etc.

The premise of this problem is "insulating materials", so it can only be found in non-metallic materials; There are inorganic non-metallic materials and organic non-metallic materials in non-metallic materials, and if you want to meet the "high temperature resistance" required by the topic, you can only look for inorganic non-metallic materials.

In the field of inorganic non-metals, more than 80 degrees Celsius is basically the critical value of "high temperature".

Step 2. According to this range, there are materials and classifications as follows: carbonates are most typical of calcium carbonate; Silicates are calcium silicate, magnesium silicate, etc.

The high-temperature resistant wire is divided into two kinds: silica gel and mica, the former is temperature resistant to 300 degrees, mostly silver-plated heart, and no woven mesh. The latter is wrapped in woven mesh, with a temperature resistance of 500 degrees, and is mostly copper-colored core.

6000 high-temperature resistant materials are not available yet.

At present, the world's high-temperature resistant material is hafnium alloy, that is, the compound of hafnium pentacarbide tetratantalum hafnium (Ta4HFC5), at standard atmospheric pressure, the melting point is 4215, it is the highest melting point in the world today. Even then, it will melt at a high temperature of 6000 degrees.

It is known that at 6000 degrees of heat, no object can withstand it. The temperature at the Earth's core is more than 6,000 degrees Celsius, but its interior is still a solid metal, mainly composed of iron and nickel. It is known that at standard atmospheric pressure, iron has a melting point of 1538 degrees Celsius and a boiling point of 2862 degrees Celsius.

Why doesn't iron become liquid or gaseous? That's because the pressure in the depths of the Earth's core is very high, about 3.5 million times the standard atmospheric pressure. In such extreme environments, the melting point of matter rises, and it is not surprising that matter deep in the Earth's core remains solid.

6000 High Temperature Resistant Materials

High-temperature resistant materials include refractory materials and heat-resistant materials. Refractory materials include refractory metals such as tungsten, chromium, and titanium, and rare earth metals such as boride, which can withstand temperatures above 1580.

Heat-resistant materials include rocket structural elements and ignition electrodes, etc., which can be used as high-temperature film insulation materials and high-temperature resistant coatings.

6000 High Temperature Resistant Materials Are:

1. Refractory materials, refractory materials include tungsten, chromium, titanium and other refractory metals and boride and other rare earth metals.

Capable of temperatures above 1580 °C.

2. Heat-resistant materials, such as rocket structural elements and ignition electrodes, can be used as high-temperature resistant film insulating materials.

and high-temperature resistant coatings, etc.

The temperature resistance characteristics of foam glue are:

1. It is not resistant to high temperatures.

Foam glue is not resistant to high temperature, foam glue, also known as sponge rubber, is a non-corrosive foam model, belongs to a rubber product, so foam glue can not withstand high temperatures, and will also show a burning state at high temperatures, the maximum withstand temperature is only 150 degrees.

2. Material characteristics.

Foam glue is a vulcanized rubber with a porous structure.

Material, so it has the effect of shockproof, sound insulation, etc., and the foam glue is lighter, has strong corrosion resistance, and is mostly used in industrial production, such as automobiles and aircraft manufacturing, and is also widely used in thermal insulation and shockproof materials.

3. Removal method.

Foam glue adheres to clothes using banana water.

To wash, first remove part of the foam glue on the clothes, then apply banana water to the foam glue of the clothes, then use a brush to wipe slowly, and rinse with water after the foam glue comes off.

There is no material that can withstand high temperatures of 6000. Refractory materials are used in various fields of the national economy such as steel, non-ferrous metals, glass, cement, ceramics, petrochemicals, machinery, boilers, light industry, electric power, military industry, etc., and are indispensable basic materials to ensure the production and operation of the above-mentioned industries and technological development, and play an irreplaceable and important role in the development of high-temperature industrial production.

Precautions for high-temperature resistant materialsAmong the high-temperature thermal insulation materials, when the temperature exceeds 1000, the thermal insulation performance of ceramic fibers is relatively good, including crystalline fibers, zirconium-containing fibers, high-alumina fibers, etc.; When the temperature is less than 1000, the thermal insulation performance of Good's energy-saving nano-microporous thermal insulation material is relatively good, and the thermal conductivity is as low as the hot surface).

Nano microporous thermal insulation material is currently known to be the best high-temperature thermal insulation material, Goode energy-saving nano microporous thermal insulation material using nano silica and infrared barrier material, thermal insulation performance is even 3 4 times that of traditional ceramic fiber thermal insulation materials.

1. According to the degree of heat resistance, the insulating materials are divided into 7 levels, such as Y, A, E, B, F, H, and C: Y grade insulation temperature resistance 90

1. Class A insulation temperature resistance 105

2. Class E insulation temperature resistance 120

3. Class B insulation temperature resistance 130

4. Class F insulation temperature resistance 155

5. H-grade insulation temperature resistance 180

6. Class C insulation temperature resistance above 200.

There is a close relationship between the insulation grade and the temperature resistance of the insulation, because the higher the temperature, the worse the insulation performance of the material. Therefore, different grades of insulation have a maximum permissible operating temperature, within which they can be safely used.

It should be noted that if the working temperature of the insulating material exceeds the insulating heat-resistant temperature, then the insulating material will age rapidly, so that it cannot be used, and may also cause safety hazards. Therefore, consumers must pay more attention when using it.

2. There are many types of insulating materials, which are generally divided into three categories: gas, liquid and solid.

1. Gas insulating materials: air, nitrogen, sulfur hexafluoride.

2. Liquid insulating materials: mineral insulating oil, synthetic insulating oil.

3. Solid insulating materials, organic solid insulating materials: glue, paper, fiber products, plastics, rubber, composite products and adhesive tapes, etc. Inorganic solid insulating materials: glass, ceramics and their products.

Relatively speaking, there are more solid insulation materials in life, and they are more complex.

High-temperature resistant materials include refractory and heat-resistant materials, inorganic compounds, and polymer materials. Refractory materials usually refer to inorganic materials that can withstand temperatures above 1580. They are used to build kilns, combustion chambers, and other building materials that need to withstand high temperatures.

It is generally made of quartz sand, clay, magnesite, dolomite, etc., such as refractory cement, magnesia brick, etc. Broadly speaking, inorganic refractory and heat-resistant materials refer to these compounds with high hardness, good brittleness, good chemical corrosion resistance, and a melting point of more than 1500. It is mainly divided into two categories: metallic and non-metallic compounds and non-metallic compounds.

The former such as tungsten, molybdenum, tantalum, niobium, vanadium, chromium, titanium, zirconium and other refractory metals and rare earth metals boride, carbide, nitride, silicide, phosphide and sulfide; The latter such as boron carbide, silicon carbide, boron nitride, silicon nitride, boron phosphide, silicon phosphide, etc. The latter has extremely important uses, and can be used as high-temperature refractory materials (such as abrasives, casting molds, nozzles, high-temperature thermowells), heat-resistant materials (such as rocket structural elements, nuclear engineering materials, electric heating elements), electrical materials (such as high-temperature thermocouples, ignition electrodes), in addition to being used as chemical-resistant materials and hard materials. Heat-resistant polymers can be used as high-temperature film insulating materials, high-temperature resistant fibers, high-temperature resistant coatings, high-temperature resistant adhesives, etc.

According to the time of high temperature resistance, it is divided into instantaneous high-temperature resistant materials and long-term high-temperature resistant materials. The former can last from a few seconds to a few minutes at 1000 10000. Among them, the ablative material is also a high-temperature resistant material.

For example, at 300 600, it can maintain its mechanical strength, chemical resistance, etc. in the air.

High-temperature resistant metal materials are mainly divided into two categories: metallic and non-metallic compounds and non-metallic compounds. The former such as tungsten, inner.

High-temperature resistant materials include refractory materials and heat-resistant materials. It is generally believed that high-temperature resistant metal materials refer to metal materials used at high temperature and high heat, all metals are heated to a certain temperature, and the crystals inside them will change, from solid to liquid, this temperature point is the melting point of the metal, the higher the melting point, the better the high temperature resistance.

In addition to high temperature resistance, the most basic thing is to have oxidation resistance, corrosion resistance, and economical and reasonable processing costs.
