Q:Which industry does the metallurgy and thermal insulating and refractory material belong to?
According to "New Economic Industrial Classification", the metallurgy and the thermal insulation refractory matter belong to C category. The manufacturing industry has 30 categories. The non-metallic mineral products industry has 303 classes. The production of building materials of tiles, stones, ect. refers to clay, ceramic tile production, building stone processing, building materials produced by wastes or drogs and subcategories 3035 produced by other building materials. The manufacture of thermal and acoustic insulation materials refers to the manufactuer of mineral insulation materials and other products, like rock wool, mineral cotton, expanded perlite and expanded vermiculite used for thermal insulation and sound insulation, but it does not include the production of 3039 subcategories, like asbestos thermal insulation and sound insulation materials, and other construction materials.
Q:Who knows the setting requirements of roofing fire barrier zone?
curtain wall style architecture should meet the following requirements: The space between the inner cavity of the base wall and curtain wall and base wall, pier between two windows, window sill wall and skirt wall should be sealed by the fire-proof sealing material at each floor. I hope I can help you!
Q:Can anyone tell me which materials are fire-proof high temperature resistant material?
Fireproof high temperature resistant materials such as: Quartz, tridymite, cristobalite, chalcedony, flint, opal, quartzite, White silica sand, diatomaceous earth, the silicon oxide (SiO2) contained in these siliceous materials is at least 90% . The silicon oxide in some pure raw material can be above 99 %. Siliceous materials are acidic in high-temperature chemokinesis. when existing metallic oxide or contact with metallic oxide, they will conduct chemical actions and conbine into fusible silicates. Therefore, if the siliceous raw material contains a small amount of metal oxide, its heat resistance will be seriously affected..
Q:whether the aluminum silicate thermal insulation material is fireproof or not?
aluminum silicate is fireproof, and the melting point is between -40 ~ 800 ℃. Aluminum: it takes the flint clay clinker as raw material, produced by resistance or electric arc furnace fusion and injection fiber-forming process. its characteristics: Low thermal conductivity, excellent thermal and chemical stability, without binder and corrosive material.
Q:How many external wall thermal insulation fireproof material are there
Class A exterior wall insulation: Rock wool, glass wool, silicate, aluminum silicate, calcium silicate, phenolic foam, foam glass
Q:how to classify the fireproofing material levels A1 A2 B1?
their classification is shown specifically in Fireproof  Specification of Building Interior Decoration Design GB 50222-95 appendix A, flammability,inflammability materials, flame retardency, noninflammability: combustion performance of A, B3, B2, B1 materials are divided into
Q:Fefractory of aluminium oxide.
Do you mean the alumina hollow ball brick? We can exchange private messages in specific.
Q:What is the difference between wear-resistant material and refractory material?
Focus is different. Some materials are called wear-resistant and refractory material. For example, refractory castable with high strength and wear-resistance, impressionable plastic material or brick. They all begin with fire-resistance and wear-resistance.
Q:what is the common materials for home fireproofing material?
1, lumber core 2,decoration panel 3 , plywood 4 density board 5,chipboard 6 fireproof panel, 7.gypsum board Hope to adopt my opinion
Q:What are the physical properties of refractory material?
The mechanical properties of refractory material include compressive strength, volume density and sclerosing, slag resistance, elastic modulus, thermal shock resistance, oxidation resistance, bibulous rate, fluidity, resilience, bond strength and slump, electrical conductivity, specific heat, heat capacity, the impact strength, linear change, torsional strength, stomatal aperture distribution, resistance to acid, etc. The use performance of refractory material include refractoriness, thermal emissivity, condensation, porosity, coefficient of thermal expansion. Thermal properties of refractory material include thermal conductivity, temperature conductivity, plasticity, the hydration resistance, creep performance. The physical properties of the refractory materials include structure performance, mechanical properties, shear strength, load softening temperature, CO erosion resistance. The structure properties of the refractory materials include porosity, alkali resistance and sintering. The operating performance of refractory material include consistency, tensile strength, the use performance and operating performance, wear resistance, bending strength, thermal properties.
