Mica piece size : 10mesh,16-40mesh
Mica is stratiform mineral ,Its composed of potassium (K), aluminum (AI),magnesium (Mg),Iron(Fe) and lithium(Li).There are different categories of mica, including white mica, phlogopite, biotite and lepidolite (Lithia mica) . White mica is widely used in industry and national defense because it is elasticity, tenacity and insulativity. it is also acid and alkali resistant, and corrosion roof, which can be stripped, with low coefficient of expansion etc.
The chemical equation: KAI2 (Si3AIO10)(OH.F)2

Application:
Mica powder can be used in paint and coating to reduce the damage of ultraviolet rays or other Light and heat damage to the paint film, promote coating acid and alkali. and insulation, and to t= strengthen its durability , freezing resistance corrosion resistance, water resistance etc. it helps to strengthen the adherence to the layer, improve its intensity, brightness, tenacity and Compaction. As a result ,it is conducive to reduce the ventilation ,to prevent speckle and chaps as well as reduce sediment in the paint. As a prior filler in paint, mica powder can be used to substitute some expensive raw materials in the paint so as to reduce the production cost.
Mica powder is also the basic raw material for mica ceramics products.
Mica powder can be applied in protecting layer of welding rods, conducting wires and electric cables.
It can be use as suspended substance in fire-fighting dry powder.
It can be taken as a filler, a shelter, a lubricating substance, a drawing of patterns in plastics, rubber, asbestos products and sealing materials.
It can also be used as a filler in degreasing agent of cosmetics, in insulating materials of high-frequent electric waves and acid and alkali products.
It can be used as coating in models of Cast metal, the brightening material in aluminum and paint in Plating bath.
- Q:How to prolong the furnace age of Induction furnace by using fireproof materials?
- magnesia solid materials have thermal endurance and erosion/ performance and its change of temperature is likely to cause cracks. properties of materials (aluminum) in such case have to be taken into consideration.
- Q:Is the refractory reached British BS standard and used for cables in China at present ceramic silicone rubber?
- The texture should be designed according to the British relevant BS standard; crosslinked polyethylene or ethylene propylene rubber under 6600V to 19000 / 33000V is not necessarily ceramic silicone. The rated voltages of a small amount of smoke and corrosive gases from 3800 & # 47 when the BS 7835-2000 is affected by fire.
- Q:what is the original materials of fireproof coating?
- Main raw material includes high-temperature aluminum surface, expanded vermiculite,closed cell perlite, high mark number cement, Fireproof paint itself is flame-retardant or non-combustible, protecting the substrate from direct contact with the air,delaying the time for catching fire and reducing the burning speed. For example, indoor thick fire retardant coating for steel structure.
- Q:Does anyone know fire-proof material of fireproof wooden door?
- Because the timber of fireproof wooden door has gone through fire retardant treatment, so it can prevent fire. Its principle: Fire-retardant treated timber has become flame retardant material itself and its fire endurance has increased. The commonly used method of fire retardant treatment for timber including: Spraying method, soaking method, boiling method, vacuum method, vacuum-pressure method. Spraying method and soaking method are generally used for timber surfaces which are no longer going through planing process, and thin plate fire retardant treatment, whose thickness is less than 10mm . Vacuum method and vacuum-pressure method have excellent flame retardant efficiency, but their equipment are expensive. Fireproof wooden door refers to the door whose fire endurance of door frames, skeleton of the door leaf, door panels made of timber or timber work reaches the provisions of "GB50045-95 design of tall buildings for fire protection".
- Q:What refractories are accessible with ease in daily life?
- Basically there have all materials. But it depends on your needs.
- Q:I am a refractory material manufacturer, sold products, money is always not back, anxious to die, what is the way?
- Looking for refractory materials network, you can conduct online transactions, funds guaranteed
- Q:I know which material is the fire resistance rolling shutter door
- Inorganic fiber cloth as curtain side replace steel fire shutter curtain of steel plate, the thickness of the inorganic fiber cloth is much thinner than the steel curtain plate and the density is very small, so the volume of the same area of ??the inorganic fiber is super fire shutter the same area of ??steel fire shutter half, and weighs only one more out of the same area a few steel fire shutter, however, the inorganic fiber super fire shutter fire but has a very good insulation properties. I hope my answers are helpful to you.
- Q:how long is the fire endurance of plasterboard?
- Gypsum board is flame retardant materials, combustion performance rating B1, but when mounted on a steel joist, it can be seen as rating A(non-combustible material) . So it is fine to use as a ceiling. You can randomly choose several samples to run some tests at the quality inspection insititute and the quality of these samples are subject to the testing results.
- Q:Development trend of refractories
- The foundation of China's refractories industry is still relatively weak, the utilization level of refractory material resources is low, the quality of refractory materials is not high, excess production capacity of ordinary products, the key products of some high-quality high technology content can be produced, but the quality is not stable, and the service life of refractory material consumption compared with foreign advanced level, there is a considerable gap. Therefore, the new trend of tracking foreign refractories science and technology development, carry out and supporting the development and application of advanced and basic theory research, to promote technological innovation of refractory materials, optimizing product structure, industrial structure adjustment, implementation of the strategy of sustainable development, it is very necessary.
- Q:What are the refractories for converter?
- Permanent layer (sintering) magnesia brick, the working lining gunning material for the working layer and the permanent layer gap, using magnesia ramming materials, MgO-C brick brick supply,
