Q:Can polystyrene foam color steel plate be used as decorative fireproofing material ?

No, only non-combustible product can prevent fire. Most polystyrene foam boards are flammable which cannot prevent fire. Polyphenyl can only retard flame, highest fire?retardant fire?rating being B1 level. Under the same conditions, fireproof performance of polystyrene foam board will be better because most extruded sheets are made by recycling materials and contain much more impurities which will affect flame resisting property. The second reason is that high temperature in extruded sheet manufacturing technique will decompose part of flame retardants. For B1 level extruded sheet, it is difficult to reach 30 burning oxygen index, while for B2 level, it is hard to reach 32. So polyphenyl board is safer.

Q:Which refractory is suitable for the tunnel kiln?

The refractories produced by the following ten manufacturers are relatively good. They are all being the top ten brands! 1. king coconut (Chinese well-known trademarks, famous brand, the nation's largest manufacturer of wood panels, large building materials chain enterprises, Hangzhou king coconut Holding Group Co., Ltd.) 2. Fuxiang (founded in 1998, the leading professional sheet production outstanding enterprises, Fuxiang Industrial Co., Ltd.) 3. Bunny (China famous brand, China Top brand, plywood industry iconic brand, large listed companies, high-tech enterprises, Edward Bunny decoration materials Co., Ltd. 4. new Millennium boat ( Chinese well-known trademarks, famous trademarks in Zhejiang, Zhejiang famous brand, well-known trademarks in Hangzhou, Zhejiang Province key forestry enterprises, the Millennium boat Group Hangzhou Huahai Wood Industry Co., Ltd.) 5. Jin Luli (China famous brand, Chinese brand-name products, Shandong Province, to wood-based panels and steel-based enterprises, hundred private enterprises in Shandong Province, Luli Group Co., Ltd.) 6. Albert (professional fire protection board development / production and marketing of the modern manufacturer, the introduction of advanced production technology industry HPL) 7. desert oasis (China famous brand lumber, China's top ten brands plate, sheet famous Chinese brand, oasis Wood) 8. Peng Che-hung (professional fire protection board development / production and marketing of the modern manufacturer, the introduction of advanced production technology industry HPL ) 9. Worldwide (professional magnesium fire plate glass production and sales of integrated large-scale well-known enterprises, famous brands Firewood industry) 10. Mogan (national key high-tech enterprises, China's largest and most influential environment-friendly decorative materials production one of the enterprises, Zhejiang Hua Yunfeng new material Co., Ltd.)

Q:what is the original materials of fireproof coating?

Main raw material includes high-temperature aluminum surface, expanded vermiculite,closed cell perlite, high mark number cement, Fireproof paint itself is flame-retardant or non-combustible, protecting the substrate from direct contact with the air,delaying the time for catching fire and reducing the burning speed. For example, indoor thick fire retardant coating for steel structure.

Q:Development trend of refractory industry

In the central provinces in Henan, Shanxi, Liaoning China main manufacturer of refractory material, which is the main origin of three China bauxite, magnesite and other refractory materials; refractories industry by the end of May 2009 more than 3236 enterprises; industry revenue reached 67 billion 52 million 540 thousand yuan, Henan Province, Liaoning, Shandong, Jiangsu, Hebei and other regions, and refractories industry in the development of better leading enterprises, such as blue and white, accessible, prco etc. at present, its sales in the industry in the proportion is still small, the largest sales is also inadequate in refractory industry in 4%. An enterprise should play a leading role in leading enterprises in the industry, and its turnover in the industry should be more than 15%. Obviously, at present the refractory industry in the leading enterprises do not have, and the refractory industry concentration needs to be improved, and the existing resources in the refractory industry integration, is undoubtedly the way this process effective and efficient.

Q:Which one is better, fire-resistant wood or steel?

Rebar would weaken and quickly collapse in the fire, and the fire resistance of a heavy log is much better than steel. In many ways, the fire resistance of a large log is equal to reinforced concrete. The heat transfer capacity of wood is 400 times smaller than steel, 8.5 times smaller than concrete. When burning, wood will form a layer of carbon in the surface, and as long as the cross-section of the timber is over a certain size, this layer of carbon it will become an excellent flame retardant layer to protect the interior of the wood from burning. So the United States and Japan and other European countries allow and encourage the use of wood structure with a large section (beam column of 8 inches or more) to construct public buildings without the need for fire treatment applied to wood surface. I hope my answer will be helpful to you.

Q:Is there requirement for radiation indicator in refractory?

All refractories have no radiated harm to environment, so there is no requirement. From the elemental analysis, magnesite. I do not know it is helpful to you. But for refractory rwa material, any chemical element is radiated, including silicon?dioxide; If they are radioactive. From the use analysis, such as bauxite, do not have use value.

Q:Can refractory be used as sealing element?

It can. For example, a kind of irregular part that is made of fiber or some injection mix is used for sealing things.

Q:who knows the fire endurance of fireproof coating?

this is not specfied , depending on design requirements. The products we made have fire endurance from 1to 4hours . We have not done any higher.how is the fireproof coating in improving fire resistance of building components? finishing fireproof coating; wood fireproof coating; fire-resistant coating for steel structure, fire-resistant coating for concrete structures, tunnel fire retardant paint, fire retardant paint for the cable. Fire retardant coating is composed of the base materials (that is film forming substance), pigments, ordinary coating additives, fire retardant agent and dispersion medium. In addition to fire retardant agent, other components functions the same as in ordinary coating, but its performance and thickness are specifically required.

Q:What are the additives and recipes of refractory?

Add FDN.

Q:Who knows what kind of fire prevention materials are there?

Plant use general steel structure more often without too much modification. If there is a need for modification, boards which can meet the requirements of fireproof are suitable, such as gypsum boards and aluminium sheets. As for coating, it is favorable to use coating that has fine powder, high density and better sealing. Hardening agent mainly depends on the specific requirements.
