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: Preparation of refractory clay
- Is it to make refractories? Add some andalusite to the refractory mortar will improve the effect.
- Q: Is there vermiculite in refractory?
- Vermiculite is usually used as lightweight material in refractory field, and its volume density is about 0.5.
- Q: Using what kind of melting aluminium furnace refractories is more appropriate?
- If it's the ordinary, you can use high aluminum refractory brick with general clay, GB/T 3994-2005 clay heat insulation refractory brick. If you need these with good material, there is high alumina thermal insulation refractory brick, GB/T 3995-2006 high aluminum heat insulation refractory brick, models have A13 and material is the alumina, A13 50 u, high insulating brick B5.Intermediate insulating brick B2, etc. Dolomite brick: good hang kiln performance, good erosion resistance, but brick is usually without f - CaO, hydration, and difficult to transport and storage, less used in the production. Magnesia-chrome bricks: good hang kiln, used in calcining zone. The disadvantage is that its thermal shock resistance is poor and plus hexavalent Cr is toxic, the production and use of magnesite chrome bricks in international countries gradually reduce. Now unit using the brick find replacements as soon as possible.
- Q: What are the features of construction class A fire resistant door ?
- 1, fireproof and thermal insulation Foam cement board is a Class A non-combustible inorganic heat preservation material which has good fireproof?performance can remain integrity after 3 hours baking at 1200℃. It can be used in buildings to improve fireproof?performance.
- Q: What are refractory materials?
- Refractories can be divided to two categories based on the shape and three categories according to the chemical nature of acidity, neutralily and alkalinity. Alkaline refractory materials are magnesia-carbon brick, magnesia chrome brick, calcium magnesium brick and magnesia-chrome bricks. Neutural refractory mateial are high alumina brick, corundum brick and clay brick. Case-hardened refractory materials are castable, ramming mass, gunning mix, coated mix, dry vibration material, etc.
- Q: How many grades of fire?rating are there for interior decoration materials?
- It can be divided into construction classification and fire resistance rating. Fire prevention for buildings. Fire prevention measures should be taken in the architectural design to prevent fires and reduce fire hazards to life and property. Building fire protection includes two aspects: fire prevention before fire disaster and measures in fire disaster, among which the former is mainly to confirm the fire resistant rating and fire-resistant structure.
- Q: What is the main material of fireproof wooden door?
- 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". Fireproof wooden door contain retardant timner, fireproof expanded perlite and fireproof?panel. Accessories: fireproof glue, fireproof hardware.
- Q: What are the differences between thermal?insulation?material and refractory?
- Just as its name implies, Thermal insulation means that it doesn't conduct heat instead it insulates heat inside, while refractory means resistance to high temperature and it will not be out of shape or damaged due to high temperature.
- Q: Who knows what material is in the center of fireproof rolling curtain?
- made of inorganic super fireproof rolling curtain: Glass fiber cloth ceramic fiber cloth (reinforced stainless steel wire) ceramic fiber blanket aluminum foil cloth. Hope my answer will help you.
- Q: What's the commonly used refractory material for ladle?
- 1. According to the refractoriness, it can be classified as follows: common refractory: 1580℃ ~ 1770℃; high grade refractory: 1770℃ ~ 2000℃; superrefractory: 2000 ℃; 2. According to the shape and demension of the product, it can be classified as follows: standard form : 230mm×113mm ×65mm of no more than four measuring scale, (demension ratio) Max: Min
