Q:What's the difference between glass fiber and mineral wool?: A fluffy short staple fiber made from mineral material. Including rock wool and slag cotton.

Q:What kinds of fire retardant coatings are there in steel structures?: Ultra thin steel structure fire retardant coating refers to the coating thickness of 3 mm (including 3 mm) within, decorative effect is better, when high temperature can expand foaming, fire-resistant limit is generally less than 2 H steel structure fire retardant coating. This kind of fireproof coating for steel structure is a solvent based system with excellent adhesive strength, good weather resistance, good water resistance, good leveling and good decoration;

Q:Fireproof rock wool board can be used as firewall?: You need to know what material the firewall is made of What are its standards and requirements? What's the function of it? When you know all about it, you won't take a piece of board to make a wall!

Q:What are the properties of fire-resistant coatings for steel structures?: Ultra thin structure fire retardant coating refers to the coating thickness of 3mm (including 3 mm) less than, decorative effect is good, high temperature can expand foaming, fire-resistant limit is generally less than 2 H steel structure fire retardant coating. This kind of fire retardant coatings for steel structures is generally solvent system, bonding strength, weathering has good water resistance, good leveling, good decorative features such as superior; subjected to fire slow expansion foam fire insulation layer to form a dense solid, the fireproof layer has a strong impact resistance, the temperature rise of steel delay, effective protection of steel member. Ultra thin intumescent steel structure fire retardant coating can be sprayed, brushed or rolled. It is generally used in building steel structures with a fire resistance requirement of less than 2 h. At present, there has been a fire resistance to meet or exceed the new ultra-thin fireproof coating for steel structure of 2 varieties of H, it is mainly based on the special structure of the poly methyl acrylate or epoxy resin and amino resin, chlorinated paraffin, compound as base adhesive, with high degree of polymerization of ammonium polyphosphate, melamine and pentaerythritol, double as the fire retardant system, adding titanium dioxide, wollastonite and other inorganic refractory material, using 200# as solvent and solvent oil compound. At present, all kinds of light steel structure, grid and so on, use this type of fire retardant coatings for fire protection. Because this type of ultra-thin fireproof paint coating, making use of thick and thin fire retardant coating for steel structure is greatly reduced, thereby reducing the total cost of the project, the steel structure has been effective fire protection, is currently promoting varieties on the market.

Q:What material is fast heated and kept warm?: Heat the heating tube and the aluminum tube with the heat preservation material.There are many kinds of insulation products, including foam plastics, mineral cotton products, foam glass, expanded perlite thermal insulation products, rubber powder, EPS granule insulation paste, mineral spraying cotton and foamed cement insulation products.

Q:Advantages of exterior wall energy saving and environmental protection heat insulation coating: At present, there are many kinds of exterior wall insulation materials in the market, which can be divided into organic insulation materials and inorganic insulation materials. Materials are inorganic active insulation materials, foam, mineral wool products, foam glass, expanded perlite insulation, powder particles insulation slurry EPS, spraying mineral cotton, foam cement insulation products, vacuum insulation panel etc..

Q:Exterior wall insulation putty powder construction needs to pay attention to what problems?: When the market holds 90% of the organic thermal insulation material at a standstill, as the fire protection level of the exterior wall insulation, inorganic materials, rock wool has ushered in an unprecedented market opportunity. Therefore, when using rock wool board, there are some we need to understand. Rock wool board insulation system for energy-saving insulation project construction should be in accordance with the review of qualified construction drawing design documents and approved by the project for energy-saving insulation project construction plan.

Q:What are common house thermal insulation materials?: Glass wool is a fibrous material made from the melting of glass or crushed glass. It consists of two kinds of short cotton and superfine cotton.Features: glass wool can maintain good insulation performance under high temperature and low temperature; has good elastic restoring force; has good acoustic performance of acoustic noise. Have good sound-absorbing effect; good chemical stability, no aging performance unchanged, thickness, density and shape can be processed according to user requirements.Main applications: short cotton is mainly made of glass wool felt and felt. It is used for heat insulation and sound insulation of buildings, heat preservation and sound insulation of ventilation and air conditioning equipment. Superfine cotton master

Q:What are the composite thermal insulation boards?: Polystyrene particle thermal insulation slurry, this kind of thermal insulation material water absorption rate is higher than other materials, use must do anti crack waterproof layer. Anti cracking and waterproof protective layer material is made up of anti cracking cement mortar and composite glass fiber net, which can effectively control the crack of protective layer for a long time

Q:What are the exterior wall thermal insulation materials?: Metal insulation material:Mainly aluminum and its products, such as aluminum plate, aluminum foil, aluminum foil, composite light plate, etc.. It uses the radiation characteristics of the material surface to obtain the heat insulation performance.Advantages and disadvantages: with this kind of surface characteristics of the material, almost do not absorb the heat on it, and the ability to radiate heat itself is also very small, this kind of material supply less, more expensive.
