CMAX Brand Silica fume is a byproduct of producing silicon metal or ferrosilicon alloys.It consists primarily of amorphous silicon dioxide (SiO2),its average granule diameter is 0.15~0.20 µm,specific surface area is 15000~20000 m2/kg.
1. Very low permeability to chloride and water intrusion.
2. Extremely high electrical resistivity.
3. Increased abrasion resistance on floors,highways,marin structures.
4. Superior resistance to chemical attack from chlorides,acids,sulfates.

- Q:What's the commonly used refractory material for ladle?
- Commonly used types of refractory material for ladle are as follows: high-alumina brick, clay brick, magnesia-carbon brick, aluminum carbon brick, magnesia chrome brick, spinel brick, corundum brick, high alumina castables, aluminum silicon carbide carbon castables, refractory castables for ladles, magnesium castables, magnesia chrome spray coating, dry vibration materials, etc. Hope it's helpful for you!
- Q:Does anyone know the refractory temperature of fire-resistant glass?
- Ordinary glass will burst under sharp temperature difference of about 70-120 degrees and toughened glass of 200 degrees. It is not yet clear for the bursting temperature differences of the refractory glass. If the overall glass is heated evenly, it will have no significant change below 600 degrees, and it will deform with the increase of temperature until melting. The fire-resistant time of the glass you said is the time to heat the glass into the extreme temperature differences it can endure, which should not be more than 10 minutes
- Q:What is the best refractory company?
- Recently, many of the activities of palladium ah, find a few big beauty shoot videos, but also to send jewelry, and draw, seems to be the need to vigorously develop the market China.
- Q:Why should graphitic refractory materials be used now that graphite can burn?
- C is inactive in nature. Carbon will not burn unless the temperature is about 2000℃, so it can't be lit generally. Coal can be lit because it contains other combustible substance which ignite carbon indirectly. While graphite, carbon black, is more pure and dense than coal., so it is hard to oxidize.Their molecular structures are also different, just like diamond is harder than graphite.
- Q:How to distinguish between class A fire resistant door and class B fire resistant door from appearance ? What are the differences between the two refractories? Thank you !
- First, the materials are the same. But the thickness of grade A and grade B fire doors is different juding from their appearances. Grade A :50. Grade B:45. Added question: Do you refer to steel fire door?
- Q:How long is the duration of fire resistance that fireproof window of level B can endure?
- The duration of fire resistance: fireproof window of level A shall not be less than 1.5h, while level B shall not be less than 1.0h. The frame of both fire proof windows A and B are made of steel, and the glass, not less than 26mm, is composite insulation fireproof glass. Monolithic fireproof glass window is neither B fire proof window nor A fire proof window, but non insulated fire proof window.
- Q:Who knows how many fire heat preservation material are there?
- Fire proof board is a fire refractory building material for surface decoration, widely used in interior decoration, furniture, kitchen cabinets, laboratories mesa, walls and other fields. Fire board is base paper (titanium powder paper, kraft paper) processed by melamine and phenolic resin, high temperature and high pressure. 1 mineral wool board, glass wool board: mineral wool, glass wool insulation. It does not burn itself, have good performance such as high temperature resistance, light quality. Such plate have evolved into plate with inorganic adhesive material as base material, mineral wool, glass wool as reinforcing material plate. 2 cement board: High strength, wide source. In the past, it is used to make fire prevention ceiling and partition wall, but its fire resistance is poor. Cement concrete component has good heat insulation and sound insulation performance. It can be used as the partition wall and the roof panel.
- Q:what's the materials of fireproof?housing?
- I'm very glad to answer for you. 1. Mobile homes in high-rise buildings, as for the interior hidden artifacts of single and multi-layer mobile homes, when its fire endurance is ruled above 1.5 h, you should choose the non-swelling large activity fire?retardant?coating; 2.as for Indoor mobile house, light roof mobile house and mobile house need to be decorated, when its fireproof limit is ruled under 1.5 h, you can choose swelling mobile house fire?retardant?coating; 3. The fire endurance of mobile houses need to be above 1.5 h, outdoor mobile houses project shoule better not choose swelling fire?retardant?coating. 4. Indoor mobile houses extremly need to be decorated, hot standby is a living place of mobile houses, bearing steel structure of equipment, bracket, the part easy to be knocked like skirt, its fire endurance needs to be above 1.5 h, you better choose fireproof?panel of mobile houses. 5. Open mobile houses, you should choose fire?retardant?coating of mobile houses suitable for outdoor, and use the coating with over one-year outdoor mobile houses project operation and the coating function without significant changes. 6. multiple layer coating should be matched with each other, the bottom layer coating should be able to be used with rust-proof paint together or have rust-proof function. 7, while choosing the fire?retardant?coating for special function, it should have over one-year project operation and verification case and matched fire-proof function.
