- Q: What is streaming fireproof material?
- Streaming fireproof material is castable refractory that can flow and degas without virbration, which is suitable for thin-wall or places that cannot be molded by vibration because of complex shapes. Well, appropriate amount of water is necessary for it. Its characteristic goes that it can be cast into various shapes of construction body without virbration and it will not reduce or not significantly reduce the performance of castable at the same time.
- Q: What is molten silicon? What refractoriness do refractories made by it have? What properties of using does it have?
- Molten silicon can be called quartz glass, which shows an amorphous silicon state. It is a liquid fusion at above 1723 degree and is an ultra-cooling state at low temperatures. It is not generated in refractories, but generated in the matrix, showing liquid state at a high temperature capable of buffering the stress with somewhat binding properties. If quartz glass is used as refractory, its function are melrly these ones. (These are what I konw for reference only.)
- 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 !
- From the perspective of appearances, grade A is 70mm, B 50mm. Their materials are the same .
- Q: What refractories are resistant to fluorine gas?
- It is recommended to use fused-quartz brick, which will produce hydrofluoric acid fluorine (an acidic gas) when water vapors. It is cheap. While it is recommended to use silica?brick if it exceeds 1,200 degrees. So acidic refractory is an advisable refractory for using. It works well if the temperature is below 1200 degrees.
- Q: How to deiron refractory?
- Our company uses magnetic separation method.
- Q: What is the fire endurance of fireproof glass cotton?
- Good thermal insulation and thermal insulation. thermal insulation and thermal insulation depends on the heat conductivity coefficient of glass?silk λ=0.043W/m2K. good fireproof?performance, it's fire-resistant capacity is more than 1000 ℃.
- Q: How many refractories are there for boiler above 1200 ℃？
- In addition to refractory brick, refractories include refractory concrete (refractory cement+aggregate), fire-resistant insulating layer (refractory cement+vermiculite powder or refractory cement + diatomaceous earth) and the like. Refractories often used are azs brick, corundum brick, direct-bonded?magnesia-chrome?bricks, carborundum brick, silicon nitride bonded silicon carbide brick, nitride, silicide, sulfide, boride, carbide and other nonoxide refractory materials, calcium oxide, chromium hemitrioxide, aluminium oxide, beryllia and other refractories. Thermal insulation refractory materials often used are diatomite product, asbestos product, insulation?board,etc. Unshaped refractories often used are repairing?mass, ramming?mass, castable refractory, plastic refractory, refractory mortar, refractory gunning mix, sling refractory, refractory coating, lightweight refractory?castables, stemming, etc.
- Q: How to choose construction external wall thermal insulation and fireproofing materials?
- Now external wall insulation decoration one board is more popular thermal insulation material. Low-carbon energy-saving insulation decoration board combine two constructions (decoration, insulation) into one, saving nearly ten processes,and construction period. Compared with conventional thermal insulation methods, it can increase construction efficiency one time by shortening 60% of the construction period. It integrates low carbon, energy conservation, decoration, fireproof and building aesthetic effect by combining like-dissolving-like binding system installation and bump fixed system, and under long-term cooperation of air handling system and waterproof system. It has excellent outdoor weather resistance, colour?retention, alkali?resistance, water resistance, scrubbing resistance, crack resistance and temperature change resistance, wear resistance, collion resistance and the paint film is firm and durable, with strong adhesive force and mould proof effect. It can provide all-dimensional thermal insulation, decoration, low carbon and energy conservation and fire prevention for construction projects.
- Q: What are the types of refractory sealant?
- According to the environmental temperature of the region, it is divided into stpl-1 type, stpl-2 type, stpl-3 type. The three models are respectively applied to sealing repair of regular and irregular crack in asphalt / cement concrete roads, highways, airport runways, which are of different temperatures. Stpl-1 type: It is suitable for pavement temperature (0℃to 80 ℃) stpl-2 type: It is suitable for pavement temperature (-15℃to 60 ℃) stpl-3 type: It is suitable for pavement temperature (-30 ℃ to 40 ℃)
- Q: How many kilns using refractories are needed? What are the furnaces respectively?
- There are many magnesia-chrome bricks and alkali insulation tiles); aluminum manufacturer roaster; The bottom of the glassworks regenerative chamber generally use the clay checker bricks, which is popularly used in many places of the steel mill. the upper of the power plant uses low pore brick and magnesia bricks. The forehearth uses the corundum bricks, and the cement plant uses dry and wet rotary?kiln (silmo brick
