- Q:How to make the service life of refractory materials longer?
- Take acid resistant refractory materials as example: the atmosphere should be acidic atmosphere, if used in an environment whose temperature is 1900℃, it would exacerbate the loss of refractory materials, so don’t use overloaded. Second, select the appropriate refractory materials according to the environment. For example, if its operating temperature is 1800℃, generally speaking, the normal use of it according to the instruction of refractory materials would be fine.
- Q:what kind of refractories is used to make the industrial silicon furnace mouth long life?
- Fused zirconia corundum brick, the smelter of the glassworks is used this kind of lining, and you can contact by private letter.
- Q:What are the fireproofing materials of the external wall included?
- Facades a fireproof material comprises three anti-cloth, fireproof cloth, plastic cloth, PVC tarpaulins, flame retardant cloth, Hair Dryers cloth, automobile tarpaulin, PVC three anti-cloth, the freight yard covered cloth, PVC coated fabric, canvas industry etc., are widely used in automobile canopy cover cloth, trains cover cloth, ships cover cloth, cloth covered open-air yard, industrial and agricultural fields; used in glass, timber, fertilizer plants, steel plants, machinery metal factory, feed mill, grain storage, container plants, oil refineries, packaging plants, paper plants, air conditioning plants, logistics, ore factory, fleet, rail, sea and so hoping to help you
- Q:Does anyone know about the classification standards of B2-level fireproof and thermal insulation materials?
- The fire-resistant differences of B1- and B2-level extruded insulation boards are as follow: B1-level materials will be smothered as soon as staying away from fire, namely, they will be extinguished after leaving fire, or be put out in 10 seconds. B2-level materials will be in low-grade combustion, namely, the fire will not get wilder, and drippings will not ignite the filter paper. I hope my answer can help you!
- Q:How many types of special refractories are there?
- Metal ceramics, high temperature coatings, high temperature fiber and other reinforced materials
- Q:Can I use ordinary cement with the addition of sand, clay, and salt as refractory material to paste the stove?
- You can add some hair, sand, yellow mud and some salt, but don’t use cement, it would lead to a thermal explosion.
- Q:The effect of a high content of water in liquid resin exerted on refractory material?
- For one thing, Substandard whiteness, transportation, low quality and the storage of refractory material may account for this. For another, a high content of moisture reduced the performance of refractory material. A high content of moisture is equal to buy water with same money in terms of trade settlement. Based on this, we can’t consider the super-standard water content from a single aspect, because the water content in refractory material is definitely super-standard, and another problem is particle size. Many people hold the idea that excessive amount of water content may revive its original performance, but it tends to have influenced the quality of refractory material.
- Q:What are the main materials in concrete fireproofing material?
- it can be roughly divided into: fire-resistant coating for steel structure, finishing fire retardant paint, tunnel fire coatings, concrete fire?retardant?coating, cable refractory coating. fire-resistant coating for steel structure is divided into: Indoor ultra-thin fireproof coatings for steel structure, indoor thin steel structure fireproofing coating, indoor thick steel structure fireproofing coating, outdoor ultra-thin fireproof coatings for steel structure, Outdoor thin steel structure fireproofing coating, outdoor thick steel fireproofing coating. I hope it can help you. Hope to adopt my opinion Thank you! )
- Q:Development trend of refractories
- The foundation of China's refractories industry is still relatively weak, the utilization level of refractory material resources is low, the quality of refractory materials is not high, excess production capacity of ordinary products, the key products of some high-quality high technology content can be produced, but the quality is not stable, and the service life of refractory material consumption compared with foreign advanced level, there is a considerable gap. Therefore, the new trend of tracking foreign refractories science and technology development, carry out and supporting the development and application of advanced and basic theory research, to promote technological innovation of refractory materials, optimizing product structure, industrial structure adjustment, implementation of the strategy of sustainable development, it is very necessary.
- Q:Which refractory is better for building 1500 degree kiln ?
- High alumina brick or 99 alumina hollow ball brick is OK, which can withstand a temperature of 1600 ℃.
