Q: Does anyone know the difference between refractory and thermal insulation material?: I will give you a relatively simple analysis. Refractory can bear above 1,200 degrees centigrade, but some refractory is not insulated. For example, refractory brick can be directly in contact with heat source, but it has little insulation effect. Refractory includes ceramic fiber, high silica and so on. And they can be also insulated. But insulation effect is not so good as insulation material. Insulation material generally can bear below 800 degrees centigrade, and it is large in thermal resistance, low in heat conductivity coefficient and high in porosity factor, thus reducing heat loss. Briefly speaking, insulated material is to store most heat, and just let a small quantity of heat run of through air, thus insulating heat. Refractory includes glass fiber, rock wool, aerogel blanket and so on.

Q: How long is the fire resistant limit for ultra thin fire retardant coating?: The fire resistant limit of ultra-thin fire retardant coating is 1.5 hours, generally fire resisting time for thin fire retardant coatings does not exceed 1.5 hours. If the time exceeds 1.5 hours, thick fire resistive coating should be uesd. There is no detailed stipulation for ultra-thin fire retardant coating, and the thickness of the inside is the fire resistance limit shall reach certain time(at least). If fire resistance limit is 2.5 hours, the thickness shall be 4.9mm. If the fire resistance limit is 2 hours, the thickness is 3.5mm. If fire resistance limit is 1.5 hour, the thickness should be 1.75mm.

Q: The primary problem, does the gas permeable brick is fired refractory bricks(refractory) ?: Yes. After moulding by casting in the firing of 1450 ° degrees.

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: How to count the construction costs of refractories?: In winter, the temperature of the the fire-resistant masonry, fire-resistant plastic, sodium silicate, phosphoric?acid castable should be maintained above 5 ℃. Usually greenhouses in which heating facilities are installed to maintain the appropriate temperaturere for the construction environment should be erected in refractory masonry. The temperature around the construction site of the industrial furnace and refractory masonry shall not be lower than 5 ℃.

Q: What are the characteristics of the carbon composite refractories?: The features of carbon composite refractories: 1. It is with an aggressive high thermal shock resistance 2. Good resistance to molten steel and slag

Q: what is the fireproofing material of engine room? who knows it ?: machine room fireproofing materials include: Inorganic binder: The main material includes sodium silicate, gypsum, phosphates, cement,ect.; refractory mineral filler: aluminium oxide, asbestos powder, calcium carbonate, perlite, cornstarch, ect.; nonflammable organic resin: it mainly includes polyvinyl chloride, perchloro-ethylene, chlorinated rubber, neoprene latex, epoxy resin, phenol resin, ect.. nonflammable fireproof addictive: it mainly has phosphorus, halogens, nitrogen organic compounds (chlorinated paraffins, tributyl phosphate,deca-brominated diphenyl ether), and boron series (boric acid, zinc borate, aluminium borate), antimony system, aluminium series, zirconium system, etc. inorganic compounds.

Q: What is shapeless refractory with high performance?: The popular ones are: Non-cement fine powder bonded castable is a functional refractory castable with nano material introduced.

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.
