Q: How to distinguish the fire resistant level of the rubber and plastic thermal insulation material?: Fire?rating grading of external wall thermal insulation materials. 1, China's national standard GB8624-97 divides the combustion performance of building materials external insulation materials into the following grades. Level A: Incombustible materials: Almost no burning materials. Level B1: Incombustible materials: Flame-like material has good fire-retardant effect. In case of fire in the air or at high temperature, it is difficult to fire and doesn't spread quickly, and when the fire source is removed after combustion, it stops immediately. Level B2: Incombustible materials: Combustible materials have a certain flame resistance. In case of fire in the air or at high temperature, it will immediately burst into flames, and easily leads to the spread of fire, such as poles, wooden frame, wooden beams and wooden stairs,ect. Level B3 : Incombustible materials: No flame-retardant effect, hidhly flammable and high fire risk. 2, The external wall thermal insulation materials could be divided according to the fire?rating. 1) thermal insulation material that has the level A combustion performance: Spraying inorganic fiber, glass wool, foam glass, ceramic foam, rock wool, foam cement and perlite obturator, and so on. 2), The thermal insulation material that has level B1 combustion performance: Special processed extruded polystyrene board (XPS) / special processed polyurethane (PU), phenolic and polystyrene powder. 3), Thermal insulation materials that have level B2 combustion performance: Molded polystyrene board (EPS), extruded polystyrene board (XPS), polyurethane (PU), polyethylene (PE), etc.

Q: Urgently!! Refractory problems, online, etc.: The service life of most refractory materials is a pair of contradictory effects. As a result, one aspect of the contradiction is porosity, and the other is volume density. The larger the volume density is, the smaller the porosity is and the more erosion resistant, but the thermal shock effect is very poor. The bigger the porosity is, the smaller the volume density is, the better the thermal shock effect is, but it is not resistant to erosion. More professionally, two curves should be made to find the intersection of the curves to adjust the recipe and production process

Q: What are fireproofing materials?: Class A incombustible material: Granites, marbles, terrazzos, cement products, concrete products, plasterboards, clay products, glass, tiles, mosaics, steel, aluminum, copper alloys; B1 class flame nonflammable materials: Ceiling materials: gypsum plaster boards, fibrous plasters, cement particle boards, mineral wool decorative acoustic panels, glass wool decorative acoustic boards, perlite decorative acoustic boards, flame retardant plywoods and medium density fiberboards, rock wool decorative panels, flame retardant woods, aluminum foil composite materials, flame retardant phenolic laminates, aluminum foil glass fiber reinforced plastic composite materials; Wall covering: gypsum plaster boards, fibrous plasters, cement particle boards, mineral wool boards, glass wool boards, perlite boards, flame retardant plywoods, flame retardant medium density fiberboards, fireproof plastic decorative plates, nonflammable double-sided particle boards, multicolor paints, nonflammable wallpaper and textile wall cloth, flame retardant simulated granite decorative plates, magnesium oxychloride cement prefabricated wall panels, flame retardant glass fiber reinforced plastic plates, PVC plastic clapboards, high-strength and lightweight composite wallboards, fire-retardant molded wood composite boards, flame retardant colored artificial boards, nonflammable glass fiber reinforced plastics, etc.

Q: What's the material of fireproof and wear-resisting floor?: Hello! Fireproof floor is non-flammable, wear resistant, and beautiful. It is made by construction steps and has many advantages: seamless, environment friendly, non-toxic, resistant to abrasion and corrosion, waterproof, dustproof, beautiful in appearance with integriality and no irritating odor The material of fireproof floor is in the form of liquid which will be in the shape of solid membrane after the completion of construction. It can be widely applied to the ground in the factory, residential ground or walls, and large areas like institutions and warehouses with high requirement on fire prevention. It can also be used in the field with no requirement on fire protection for it is beautiful in apperance and just like epoxy floor, and with good cost performance, it is a kind of commonly used decorative material. Hope it's helpful for you!

Q: What kinds of fireproof materials does the safe use?: The fireproof materials of safe, copper is one of the most widely used material of locks for its good mechanical performance, corrosion resistance and processibility and beautiful colors.

Q: what textures of furnace refractories are good?: Common ceramics use ordinary clay and high alumina bricks, as well as thermal insulation bricks, calcium silicate boards and fiber cotton. The vessels fired with potter's earth are called pottery, and the vessels fired with porcelain clay are called porcelain. Ceramic is generic term of pottery, stoneware and porcelain. The objects taking the two different types of clay as the raw materials, like, potter's earth and porcelain clay, and made through the technological process of ingredients, forming, drying and roasting, ect. can be called ceramics.

Q: Does the aluminum silicate thermal insulation material fireproof?: How does its fireproof?performance? this is the material that the decoration master worker recommands to me, how do you think of it?

Q: What are fire resistant level standards of class A fire resistant door?: Executive standard: GB12955-2008 Fire Door. Fire resistant level: Class A: 1.5h, B:1.0 h, C: 0.5 h. Thickness of door leaf: Class A: 50mm, B 45mm, C 40mm. Doorframe Specification: Class A, B, C. Door leaf form: Single open, double open, single open with glass, double open with glass, single open with glass and bright, double open with glass and bright, with a bright picture, Zimu glass Zimu glass with light. Doorframe Specification: Class A, B, Door leaf form: Single open, double open, single open with glass, double open with glass, single open with glass and brightness, double open with glass and brightness, double open with a lager door leaf and a smaller door leaf, double open with a lager door leaf and a smaller door leaf with glass, double open with a lager door leaf and a smaller door leaf with glass and brightness. Standard sizes: In line with GB5824-86 Hole Size of Building Doors and Windows."

Q: What are the additives and recipes of refractory?: Water reducing agent is to evidently reduce mixing water content while keep the slamp value of refractory castable almost invariant, also known as fluid loss agent. Water reducing agent itself cannot have chemical reaction with material component or compose new chemical compound, but it just seemingly has physical and chemical reactions. The binding agent of refractory castable is calcium aluminate cement combined with clay and oxide micro powder. In commonly used water reducing agents, the inorganic includes sodium pyrophosphate (Na4P2O7), sodium tripolyphosphate (Na5P3O10), sodium hexametaphosphate [(NaPO3) 6], super sodium polyphosphate (Na2P4O11), sodium silicate (Na2O · nSiO2 · mH2O), and so on; the organic includes lignosulphonate water reducer (sodium lignosulphonate, calcium lignosulphonate); naphthalene water reducer (naphthalene sulfonate or naphthalene homologues with formaldehyde condensate): water soluble resin water reducing agent (sulfonated melamine formaldehyde resin, abbreviated as composite of melamine water reducer).

Q: what materials can make external wall fireproofing paint have the fireproofing effect: Fire retardant coating material is composed of the base material (film forming substance), pigments, ordinary paint additives, fire retardant agent and dispersion medium. Except fire retardant agent, the function of other coating component is same to the commom coating, but the performance and the dosage have special requirements.
