General Introduction of mica
1.Mica is a kind of rock-forming minerals. Its form is platelike or flaky.The colour is variable with the differences of chemical composition. Mainly Fe content increase will make the colour be darker.
2. The characteristics of mica contains: insulation,high temperature resistant,lustrous appearance, stable physical and chemical property,good heat insulation, excellent elasticity and high toughness etc.
Particle Size of mica
It contains 3-5mm,1-3mm,15mesh,20mesh,40mesh,60mesh,80mesh ,100mesh,200mesh,325 mesh ,400 mesh etc.
Physical Property of mica
Diameter-thickness. Ratio | Whiteness | Refractive Index | Specific Gravity (g/cm3) | PH | Moisture | Sand Content | Colour |
1:30 | 50-70 | 1.58 | 2.8 | 6.5-7.5 | ≤0.5% | ≤1.0% | Silver white |
Chemical Composition of mica

Application of silver mica
Muscovite is used in industry mostly, the second is phlogopite.Mica is used widely in building materials industries, fire-fighting industries, fire extinguishing agent, electric welding rod, plastics, electric insulation, papermaking, asphalt paper,rubber,pearl pigment etc.
- Q: What are the fire endurance requirements of class A fire resistant door ?
- Fire endurance of class A fire resistant door is 1.5h. According to the latest fire door requirements, in FMA FMB FMC three forms, A, B and C represent categories, such as FMA on behalf of Class A fire doors (ie thermal insulation fireproof door). Fire endurances of class A,B and C fire doors are 0.5 1.0 1.5 2.0 3.0. Therefore, the fire resistance of fire door needs to be designed and the design paper will make it clear in general.
- Q: How long can gypsum board endure fire?
- Fire endurance refers to the fire-resistent limit of the whole system of light-gauge steel structure coupled with gypsum. It does nor merely refers to gypsum board. Fire endurance of the common gypsum board with the thickness of 9.5mm keeps 1.5 hours. Those gypsum board with the thickness of 12mm has a fire endurance of 3 hours.
- Q: What is the best refractory company?
- Palladium activity is very rich ah, Sina micro-blog introduced a lot of jewelry related content, style is very unique, see people could not help but want to store to buy impulse.
- Q: The primary problem, does the gas permeable brick is fired refractory bricks(refractory) ?
- gas permeable brick have two types:built-in type and external mounted type. the built-in gas permeable brick and the external mounted gas permeable brick are usually made by fire burning, and small part of bricks are made by the low temperature heat.
- Q: What's the refractory material?
- Frequently used refractory material: AZS brick, corundum brick, direct-bonded?magnesia-chrome?bricks, carborundum brick, silicon nitride bonded silicon carbide brick, nonoxide refractories like nitride, silicide, sulfide, boride and carbide, and oxide refractories like calcium oxide, chromium hemitrioxide, alumina, magnesium oxide and beryllia. In general, the refractory material include the above. For more information, you can ask for specific advice.
- Q: Who knows about the fire endurance of sintered shaly hollow bricks?
- Sintered shaly hollow bricks of Chu area have high intensity. The average compressive strength of them is up to 15.8, which matches with M7.5 cement mortar that has advantages of low water absorption, and good anti efflorescence performance. The fire endurance of sintered shaly hollow bricks should not exceed1050 degrees otherwise they will burn excessively. I, actually, think that the temperature should be controlled within 980 degrees. I hope my answer may help you.
- Q: who knows the uses of refratories?
- Of course, the role of the refractory material is fireproof, generally used in large buildings. It can reduce casualties and economic losses caused by the fire. it also can be used on the chemical instruments. ! !
- Q: I would like to ask a friend that how much is the fire endurance of level A fireproofing glass?
- fireproofing glass is mainly control the spread of fire or smoke insulation, and is a measurable fireproofing material, the fireproofing effect is evaluated by the fire resistance. It is through a special process and treatment, and it is a special glass which can maintain its integrity and thermal insulation in the specified fire resistance test. Original glass of fireproofing glass can be used float flat glass, and composite fireproofing glass also can use monolithic fireproofing glass.
- Q: How is the development of Xinmi refractories industry? What's its advantages and disadvantages?
- The disadvantage is too small yard, vicious competition among each other and confusion in the market, which should be the inferiority of national refractory industry . Xinmi Refractory is well developed in recent years, mostly acidic and neutral refractories. It is still relatively rare to use in iron parts, steel pile with a satin and other basic refractory slide .
- Q: what materials can make external wall fireproofing paint have the fireproofing effect
- Adding flame retardant or fire retardant materials can be fireproofing, which commonly referred to as the external walls of fire retardant coating or fire retardant coating. Principle: Fireproof paint itself is flame-retardant or non-combustible, so that the protected base material can not directly contact with the air in order to the ignition delay and reducing the burning speed; except that, it also has a lower thermal conductivity, which can delay the transfer of flame temperature to the protected base material; fireproof paint thermal can decompose non-combustible inert gas by heating to dilute the thermal decomposition of combustible gas in protected object, making it difficult to burn or slow down the speed of burning.
