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 substitutesome expensive raw materials in the paint so as to reduce the production cost.
Mica powder is also the basic raw material for mica ceramicsproducts.
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.
- Q: Do you know what the main indicators are for the inspection of refractory materials? Thank you very much for your requests and reports
- Fire resistance, combustion performance, combustion heat value, fire resistance, high temperature resistance, fire rating test and so on. Regular testing institutions are generally reported, Qingdao standard also can, the results are more accurate.
- Q: What's the maximum temperature that the high-temperature resistant refractory ceramic fiber cotton can endure?
- It depends on what material the ceramic fiber gasket uses. It’s usually referred to high temperature gasket made from ceramic fiber paper. It is generally classified into normalized form and high alumina type, of which the former can resist the maximum temperature of 1260℃ and its continuous use temperature is 1000℃, and the latter can be used for a long period at the temperature of 1200℃. Nichrome wire, stainless steel wire and glass fiber are reinforced. Ceramic fiber coating cloth and slag cloth, sintering ceramic fiber cloth and ceramic fiber fumigation cloth) Characteristics of the ceramic fiber cloth: It has high temperature resistance, low heat conductivity, thermal shock resistance, low thermal capacity; superior insulating property at high temperature, long service life; resistance to nonferrous metals like molten aluminum and zinc erosion; low and high temperature strength; innocuity with no adverse effect on the environment.
- Q: How long is the fire-fighting time of A class fire resisting window?
- Fire resisting window' duration of fire resistance: A class window, fire insulation ≥1.50h and fire resistance integrity ≥1.50h. Fire resisting window can be divided into three kinds: 一. window frame and sash framework adopt fire resisting window with steel manufacture ; 二. window frame and sash framework adopt fire resisting window with wooden manufacture; 三. window frame adopt steel and sash adopt wooden material or window frame adopt wooden material and sash framework adopt fire resisting window with steel material.
- Q: Refractory materials are needed for casting metallurgy.
- Refractory material used in foundry work is that refractories for cupola furnace? Cupola is a high temperature furnace which is used for melting molten iron, and refractory material adopted is mainly low iron high grade clay brick and clay lightweight insulation bricks, etc.foundry ingot refractory material is pearl sand (also known as pearl jewelry sand, fused ceramic, ceramic sand) it is made of high quality bauxite material by arc melting furnace.
- Q: Would you like to know if there are any enterprises in Mianyang that need fire-resistant materials?
- Smelting and casting needs, need more long double
- Q: What parts of cement kilns are refractories used on?
- These parts are decomposition furnace, smoke chamber, kiln, kiln hood, grate?cooler, tertiary air duct and coal pipe.
- Q: What are the advantages and disadvantages of new external wall fireproof and thermal inuslation matertials?
- Advantages: 1)Low requirements on the waterproof, weather resistance and other technical indicators. The dry wall and gypsum plastering mortar, etc. can meet the requirements and can be easily obtained; 2) The inner insulation material are separated by the floor, and construct within a height of only a storey , without erecting scaffold ; 3) In the hot summer and cold winter or hot summer and warm winter area, the inner insulation meets the requirements; 4) The glass beads overcome the shortcomings of expanded perlite, like, large amount water absorption, easy powdering, big volumetric shrinkage in the slurry mixing process, easily leading to post-insulation product performance degradation and hollowing, cracking, and also make up for the defects of polystyrene particles organic materials, like, flammable, poor fire performance, producing harmful gas at high temperatures and anti-aging, poor weather resistance, poor workability and large rebound in construction, ect. Disadvantages of external wall insulation : 1) Since the ring beam, slab and column structure would cause thermal bridges, leading a greater heat loss; 2) It is of low intensity, high water absorption, easy to shrink and crack. The insulation system is prone to cracking, leaking or loss and other common quality problems, especially it is easy to crack at the seams, thus being difficult to exsit as long as the building. 3) It is inconvenient for the users to redecorate and hang ornaments; 4) It takes up indoor used space;
- Q: Who can tell me the properties and classification of insulating refractories?
- Burn out addition method. This method is sawdust or combustible additives into mud. Sublimation mixing and extrusion method, semi dry or slurry casting moulding, drying and sintering. Combustible or sublimation additives in the firing process of burned, leaving the empty hole, become insulating refractory products.
- Q: what textures of furnace refractories are good?
- First, it depends on the kiln. If it is the cubic kiln, the top and the wall portion should use alumina hollow ball bricks. The bent seal and kiln car use heavy corundum bricks. If it is the consecutive kiln, the burning zone shall all use the alumina hollow ball bricks, and both the burning zone bent seal and the brick kiln car bent seal use the heavy corundum bricks. Ifit is the pit furnace, furnace walls and roof use the alumina hollow ball bricks, and the bottom of the furnace use heavy corundum bricks.
- Q: Which fireproofing materials factory is the best in Xiangyang?
- Xiangyang Shenglaide Door Technology Co., Ltd. Location: Taibai Road, Fancheng District, Xiangfan, Hubei Province Xiangyang Ai'ruite Door Technology Co., Ltd. Location: Scientific and Technical Pioneering Park, Xiangcheng District, Xiangfan, Hubei Province Xiangyang Innovation and Ideal Manufacturing Co., Ltd.
