Q:which is better as household fireproof material ?
If it is from the perspective of fire rating inorganic active insulation material for wall thermal, cement foam insulation board, glass beads of insulation movitrified micro bead thermal insulation mortar, rock wool board, glass wool board, ect.. thermal insulation material are Class A fireproofing, polyphenyl board, extruded sheet, phenolic foam board, Polyurethane board, ect..belong to B1 level fireproofing, if it is used for external wall thermal insulation in decorative board, then rock wool board is more often used.
Q:What is the biggest difference between refractory bricks and clay refractory bricks? Where can I find information on the refractory bricks?
You can look up knowledge manual of refractory material to find phosphatic material, etc. Xinjiang refractory bricks, castable refractory, refractory material, silicious, corundum and alumina-magnesia: High alumina and clay refractory bricks can be divided into
Q:Who knows the roofing fireproofing and waterproof material?
If you should do home water proofing, I recommend the acrylate waterproof coating with high elasticity of Qinglong waterproof, because it has good aging resistance, extensibility, elasticity, binding property and film-forming property; waterproof layer is a closed system, the overall waterproof effects are very good, especially for the construction of heterotypic structure base and roofing, walls, toilet and bathroom, basement and other buildings waterproof and anti-seepage engineering in the conditions of non-permanent immersion;
Q:Kinds of refractory mortar
Refractory mortar can be divided into ordinary refractory material and special refractory material. Ordinary refractory materials can be divided into acidic, neutral and alkaline refractory materials chemical properties. Special refractory material can be divided into high temperature oxide, refractory compounds and high-temperature composite materials according to their components. Furthermore, according to refractoriness, it can be divided into general refractory products (1580 ~ 1770 ℃), high grade refractory products (1770 ~ 2000 ℃) and super refractory products (2000 ℃ above). It can be divided into bulks (standard bricks, special-shaped bricks, etc.), special shapes (crucible, sagger, pipe, etc.), fibrous (aluminum silicate, zirconia filter and boron carbide , etc.) and indefinite shape (refractory clay, pouring materials and ramming mass, etc.). According to the sintering process, it is divided into sintered products, fused cast products and melting jetting products.
Q:What needs to be noted when choosing and using blast furnace fireproof materials? Who knows?
there are different temperatures in various parts of the blast furnace, thus using different types of refractory.
Q:Who knows what is the external wall thermal insulation materials for level A fireproofing?
external wall thermal insulation materials level A fireproofing: Incombustible building material is a material that does not occur any burning. Class A1: Monomer inorganic non-combustible. Noncombustible means no open fire. Class A2: Non-flammable organic compound is namely composite materials and non-flammable, the amount of smoke must be qualified. Class B1: nonflammable building material: non-flame material has good flame resistance. It is difficult to fire under the condition of open fire in the air or high temperature, and it is not easy to quickly spread, and when the combustion source is removed, the combustion will stop immediately. Class B2: combustible building materials: flame material has a good flame resistance. In case of fire in the air or at high temperature, it will immediately burst into flames, and easily lead to the spread of fire, such as wooden column, timber roof truss, timber beam and wooden stairs.
Q:What's the commonly used refractory material for ladle?
1. According to the refractoriness, it can be classified as follows: common refractory: 1580℃ ~ 1770℃; high grade refractory: 1770℃ ~ 2000℃; superrefractory: 2000 ℃; 2. According to the shape and demension of the product, it can be classified as follows: standard form : 230mm×113mm ×65mm of no more than four measuring scale, (demension ratio) Max: Min
Q:How long can gypsum board endure fire?
General gypsum plaster board with a thickness of less than 12mm has a fire endurance which is less than half an hour. It is clearly stipulated in Clause 2.0.4 of "Specification of Fire-resistance of Decoration Design in the Interior of Buildings" that "gypsum board, mineral wool board and acoustic board whose combustion performance reach at B1 grade installed on steel joists can be used as A-grade incombustible materials. Although the gypsum board is non-combustible material, we need to examine materials' stability in the face of fire and their fire retardant limits besides exmine their fire prevention standards. Fire retardant limit refers to the ability and time that materials can resist fire when encounting fire and taking palce changes.
Q:How long is the fire endurance of fire resistant rolling shutter door?
According to the new national standards GB_12955-2008 for fire doors from January 1, 2009, fire doors are classified acoording to thermal insulation fireproof door(A),part heat insulation fireproof door(B) and non thermal insulation fireproof door(C), rather than thermal insulation fireproof door. At the same time, the original fire endurances of class A, B and C fire doors are adjusted to 1.5h, 1.0h and 0.5h respectively. So, GB is 1.5h
Q:what's the classification of fireproof materials?
Fireproof materials are used in construction, in various forms and it has played an absolute role in modern fireproofing, common fireproofing materials include fireproof panel, fire door, fireproofing glass, fire retardant coating, fireproof bag,etc Or the material itself has a high temperature resistance, heat-resistant, flame-retardant properties. Most of them are used for the construction industry.
