Q:I am a manufacturer of refractory materials. I would like to receive some orders from abroad. I would like to know what foreign trade companies in Dalian place foreign orders abroad
You don't give a cent to this question, no one will answer it
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:Can the teflon material resist fire?
Teflon material does not burn, but the heat resistance temperature of it is about 300℃.
Q:How should fireproof building materials be ranked?
5. Civil building 5.1. Fire resistance rating, number of layers and floorage of civil buildings 5.1.1. Fire resistance rating of civil buildings should be classified into four levels of first, second, third and fourth. Unless otherwise specified in the code, the combustion performance and fire endurance of building components with different fire resistance rating should be no less than that of the regulations in Table 5.1.1. Table 5.1.1: Combustion Performance and Fire Endurance (h) of Building Components (Figure) Note: 1. Unless otherwise specified in the Code, the fire resistance rating of the building with wooden pillars as load-bearing and incombustible material as the building wall should be the fourth level; 2. For the suspended ceiling of the building with the second level of fire resistance rating, if it uses non-combustible component, it won't be limited in its fire endurance; 3. For buildings with the second level of fire resistance rating, if it is really difficult for the partition wall of rooms with the area of no less than 100m2 to implement the regulations of the Table, the partition wall can adopt the non-combustible component with fire endurance of no less than 0.3h; 4. For buildings with the first or second level of fire resistance rating, if it is really difficult for the partition wall of both sides of the evacuation walk to implement the regulations of the Table, the partition wall can adopt the non-combustible component with fire endurance of no less than 0.75h. 5. Fire endurance and combustion performance of the residential building component can be implemented in accordance with the provisions of current national standard GB 50368 "Residential Building Code".
Q:What kind of materials are needed to make refractory bricks?
Refractory materials generally refer to inorganic non-metallic materials with fire resistance above 1580℃. It plays an important role in metallurgy, nonferrous metals, chemical engineering, ceramics, and industrial production. Different industry needs different materials. You can turn to the knowledgeable internet.
Q:What's the B grade fireproofing material?
B1 grade ceiling material: gypsum board, fobrous plasterboard, cement particle board, mineral wool decorative acoustic panels, glass wool decorative acoustic board, perlite decorative acoustic board, flame retardant plywood, flame retardant medium density fiberboard, rock wool decorative sheet, flame retardant wood, aluminum foil composites, flame retardant phenolic laminate, aluminum foil glass fiber reinforced plastic composite material, etc.; B1 grade wall material: gypsum board, fibrous plasterboard, cement particle board, mineral wool board, glass wool board, perlite board, flame retardant plywood and medium density fiberboard, fireproof plastic decorative sheet, nonflammable double-sided particle board, multicolor coating, flame retardant wallpaper and 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 wooden composite boards, flame retardant colored artificial boards, nonflammable glass fiber reinforced plastics, etc.
Q:Who knows how many poured refactory material are there?
Casting refractory material, refractory material used often are AZS brick, corundum brick, direct bonding magnesia chrome brick, silicon carbide, silicon nitride bonded silicon carbide brick, nitrides, silicides, sulfide, boride, carbide and other non oxide refractory materials; calcium oxide, chromium oxide, aluminum oxide, magnesium oxide, beryllium oxide and other refractory materials.
Q:The effect of a high content of water in liquid resin exerted on refractory material?
For one thing, Substandard whiteness, transportation, low quality and the storage of refractory material may account for this. For another, a high content of moisture reduced the performance of refractory material. A high content of moisture is equal to buy water with same money in terms of trade settlement. Based on this, we can’t consider the super-standard water content from a single aspect, because the water content in refractory material is definitely super-standard, and another problem is particle size. Many people hold the idea that excessive amount of water content may revive its original performance, but it tends to have influenced the quality of refractory material.
Q:What are some of the new refractories and what are their characteristics?
Alumina, a better refractory material, is a new type of ceramic refractory, the characteristics are unclear.
Q:What's the fire resistance rating of the exterior fire retardant coating?
Exterior thick fire-resistant coating for steel structure can reach the first level of fire resistance, thin fire-resistant coating for steel structure can be fire-resistant for three hours, and ultra-thin fire-resistant coating for steel structure can just be within the second level of fire resistance.
