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 long does it take for refractory cement to solidify?: 1. First you should be aware of the concepts of condensation and condesation time. Refractory cement belongs unshaped refractories, which when added water or liquid binding agent to mix, the agitation material will gradually lose thixotropy or plasticity and become in a state of solidification, thus is solidified. The time needed to finish the process is called solidification time. The whole process is divided into initial and final set. When beginning to lose plasticity called the initial setting, when called plasticity completely lost the final setting. 2. For refractory cement, the solidification time depends on the matching of the material and the parts and using methods. Under normal circumstances, in order to meet the requirements of time of construction, the initial set time should be no shorter than 40min, and the final set time should be no longer than 8H 3. There are also some exceptions. When refractory cement is used for spraying and injection operation together with other refractory castable, the set time is required as short as possible, sometimes flash set is required to prevent the occurrence of peeling or collapse of the spraying layer.

Q: What are the qualifications of refractory industry?: 1 business license 2 tax registration certificate 3 organizing institution bar code 4 production permit

Q: How long usually will the A-level fireproof materials prevent the flame?: Having a fire resistance test on any building components -----according to the standard time-temperature curve. This period starts from the time when affected by fire and ends up with losing the ability to support or to insulate fire or the integrity of the components. It can be expressed in hours. A-level fireproof materials can last for 2 hours.

Q: What's the organzational structure of refractory material?: Ingredients (harmful); phase composition. The main components of refractory material include chemical composition and phase composition. The addtional components include main crystal phase, matrix, crystal phase, chemical composition

Q: What is the most reasonable drying heating curve of magnesia refractories? Products of less than 0.5T: You'd better oxidize magnesia preformed unit at room temperature for a longer period of time, then bake it, during which, it's enough to control the maximum temperature within 300 degrees. During the middle process, usually heating up for 4 hours and keep warm for 3 hours. The entire heating up process takes about 20 hours. If it is the site operation magnesia-based castable, it should be heated slowly in the early stage, and pay attention to keeping warm at 80 degrees Celsius. Every manufacturers has their own heating curves, so do not blindly adopt existing curves, try to make your own heating curve.

Q: What high-molecular polymers can be used as fire-resistant material binder?: Lignin is the least expensive.

Q: what is the fireproofing material of engine room? who knows it ?: machine room fireproofing materials include: Inorganic binder: The main material includes sodium silicate, gypsum, phosphates, cement,ect.; refractory mineral filler: aluminium oxide, asbestos powder, calcium carbonate, perlite, cornstarch, ect.; nonflammable organic resin: it mainly includes polyvinyl chloride, perchloro-ethylene, chlorinated rubber, neoprene latex, epoxy resin, phenol resin, ect.. nonflammable fireproof addictive: it mainly has phosphorus, halogens, nitrogen organic compounds (chlorinated paraffins, tributyl phosphate,deca-brominated diphenyl ether), and boron series (boric acid, zinc borate, aluminium borate), antimony system, aluminium series, zirconium system, etc. inorganic compounds.

Q: Which one is the best refractory material?: 1, Acid refractory usually refers to the refractory material whose content of SiO2 is more than 93% , and is characterized by erosion resistance to acid slag under high temperature , but it is easy to react with alkaline slag. Commonly used acid refractory materials include silica bricks and clay bricks. 2, Alkaline refractory material is a kind of refractory material whose components are magnesium Oxide or the mixture of magnesium oxide and calcium oxide. 3, Aluminosilicate refractory refractory material refers to refractory material which makes SiO2-Al2O3 as the main component. According to the content of Al2O3, it can be divided into semi silica (Al2O3 15~30%), clay (Al2O3 30~48%), high alumina (Al2O3 > 48%). 4, Fusion-cast refractory material refers to a kind of refractory product that melt the batch through some certain methods refractory products, and then pouring into a certain shape. 5, Neutral refractory materials mean that under high temperature, don’t react with acidic or alkaline slag. 6, Special refractory material is a new type of inorganic nonmetal material, which is developed on the basis of traditional ceramic and refractory materials. 7, The amorphous refractory material is a mixture of refractory aggregate and powder, binder or admixture, which can be used directly or after adding the appropriate liquid mixing.

Q: Detailed description of magnesia dolomite refractory material?: In the cement kiln firing zone, the f-CaO in the dolomite material is easily combined with the C2S in the clinker to form C3S, so the kiln cover can be easily hung, and the kiln crust and the refractory brick are firmly combined and easy to maintain.
