If you’ve kind enquiries, please don’t hesitate to let us know. ^_^

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:Who knows the roofing fireproofing and waterproof material?: Colorful glass?fiber asphalt shingles the roofing through special materials treatment just like wearing a waterproof, fireproof coat, water rolling down from the roof is similar to the effect of lotus leaf drops, the wall will be always in the dry state, having excellent waterproof, mould proof, efflorescence and weathering. It can prevent the growth of moss and keep the surface clean. And let your roof does not change color for a long time. Colorful fiberglass asphalt shingles materials are widely used in: All types of buildings roofing waterproofing, leak, fire, pollution, wind, and mould proof and moisture-proof of libraries and archives. The color retention of ancient architecture and protection of human cultural relics. Through the number of ten million square meters of engineering applications and two decades of practical test, it welcomed by users.

Q:What's the fire?retardant material of roller shutter fire resistance door ?: I am happy to answer this question. Fire resistant rolling shutter door is generally filled with aluminum silicate fiber cotton inside. fire resistant rolling shutter doors are divided into special inorganic fireproof rolling shutter door and steel fire resistance rolling shutter door. The former has better fireproof?performance, but the later has certain wind load resistance and can be installed outdoors.

Q:What is the upper temperature limit for refractory materials?: The key depends on what refractories you use

Q:What's the feature of construction external wall fireproof and thermal inuslation matertial?: It has properties of low heat conductivity coefficient, low density, high flexibility, fireproof and waterproof. Its heat conductivity coefficient at normal temperature is 0.018W / (K · m) . The thermal insulation property is three to eight times that of the traditional materials. And it is completely waterproof. [2] Thermal insulation lining has properties of low heat conductivity coefficient, low density, high flexibility, fireproof and waterproof. Light, generally about10-96kg / m3, 20kg / m3 or less is felt, 24-48kg / m3 is middle-hard plate, 48-96kg / m3 is hard plate, wherein 48kg / m? can be used as ceiling, with softening point being 500 ° C , thermal insulation 300 ° C. It is widely used in the United States, k =0.9. Calcium silicate thermal insulation product is developed in 1970s in China. With high compressive?strength, low heat conductivity coefficient, recycle and easily construction, it is widely used in the power system. In China, small workshop?production were the most common, then four production lines were gradually introduced from America, including instant fiber forming, dry method punched felt, which are advanced and quality, temperature endurance up to 800-1250 ° C.

Q:Why can aluminium hydroxide not be used to make refractory material?: Hope my answer is helpful to you. It decomposes and produces aluminium oxide and water after heating, chemical equation for the reaction is: 2Al(OH)3=△=Al2O3+3H2O. Aluminium hydroxide can't be directly used to make refractory material because aluminium hydroxide is not stable.

Q:What kind of refractory materials should be used for the intermediate frequency furnace to smelt manganese?: I’d like to make supplements to upstairs that aluminum silicate refractory materials should be needed considering heat insulation.

Q:How to choose refractory material: Refractory fiber in different furnace material requirements are different, I would like to know is methanol as a protective gas, fire fiber, cotton material what?.

Q:What's meaning of CN of fire-resistant material?: The commonly used preparation methodsinclude shock compression, high-pressure pyrolysis, ion implantation, reactive sputtering, plasma chemical vapor deposition, electrochemicaldeposition, ion beam sputtering, , low-energy ion radiation, pulsed arc discharge,pulsed laser inducing, etc. But the compounding result of superhard materialis not ideal due to deposition of amorphous CN film, nanometer level sizedC3N4 crystalline grain set in the amorphous film and few large graincrystal.

Q:Which industry does refractory belong to? Does it belong to construction industry?: I do not recognize all the answers. No matter what kind of refractory can be used in construction. Biulding syove or kiln is construction. So personally, it belongs to construction indusrty.
