$Tabular Alumina For Refractory With Good Delivery$

Q: What's the feature of construction external wall fireproof and thermal inuslation matertial?: It has properties of low heat conductivity coefficient, low density, high flexibility, fireproof and waterproof. Its heat conductivity coefficient at normal temperature is 0.018W / (K · m) . The thermal insulation property is three to eight times that of the traditional materials. And it is completely waterproof. [2] Thermal insulation lining has properties of low heat conductivity coefficient, low density, high flexibility, fireproof and waterproof. Light, generally about10-96kg / m3, 20kg / m3 or less is felt, 24-48kg / m3 is middle-hard plate, 48-96kg / m3 is hard plate, wherein 48kg / m? can be used as ceiling, with softening point being 500 ° C , thermal insulation 300 ° C. It is widely used in the United States, k =0.9. Calcium silicate thermal insulation product is developed in 1970s in China. With high compressive?strength, low heat conductivity coefficient, recycle and easily construction, it is widely used in the power system. In China, small workshop?production were the most common, then four production lines were gradually introduced from America, including instant fiber forming, dry method punched felt, which are advanced and quality, temperature endurance up to 800-1250 ° C.

Q: who knows the fire resistant levels of fireproofing glass?: Fireproofing glass is a kind of special glass which can keep its integrity in the regular fire resistance test, and it can be divided into three classes: fireproofing glass,fireproofing glass A class is a kind of fireproofing glass that can satisfy the requirements of refractory integrity, fire resistance and thermal insulation. Including composite flameproof?glass and perfusion type fireproofing glass . This kind of glass has the properiyies of transmittance, fireproofing ( smoke insulation, fireproofing, and keeping out thermal radiation), sound insulation, shock resistance, and it's suitable for steel and wooden fire door of building decoration, windows, varnishing, partition walldaylighting?roof,ceiling?screen,perspective floor and other construction components demading for transparency and fireproofing. Class B, it's a kind of fireproofing glass that can satisfy the requirements of refractory integrity, refractory and thermal insulation at the same time. Such kind of fireproofing glasses mostly are composite fireproofing glasses and has characteristics of transmittance,fireproofing and smoke insulation. Class C, it's a kind of monolithic fireproofing glass that only satisfies the requirements of refractory integrity. This kind of glass has characteristics of transmittance, fireproofing, smoke insulation and high strength,etc. It's suitable for fireproofing glass partition wall, fire Windows, outside curtain wall and other places without insulation requirements. hope it can help you.

Q: What are the electrical fire protection materials?: Electrical fire protection materials are the following: 1, fire proof board It is the most commonly used materials in the market, which has the advantages of fire prevention, moisture, abrasion, oil, easiness to clean, and more varieties of colors. Installed in the building exit corridors, stairs and corridors, such as fire ceiling ceiling, it can ensure that people can be evacuated safely, and to protect people from the spread of the fire. 2, fire proof door, fire proof door is divided into wooden fire door, steel fire door and stainless steel fire door. Fire proof doors are usually used for the opening of the firewall, the entrance of the staircase, the evacuation of the aisle, the openings and other parts of the pipeline, the fire prevention, playing an important role in reducing the loss of fire. 3, fire shutter It can be set in the location where it is not convient to install a fire proof wall, fire shutter generally has functions such as good fire resistance, heat insulation, smoke, compression, anti aging, wear and corrosion. 4, fireproof and mothproof wood fire wood moth is made by putting ordinary wood into the solution containing calcium and aluminum, and then into the solution containing phosphate and silicate. In this way, two ion will be undergong chemical reaction in the wood, forming materials similar to the ceramic, and filling the gap of cells and tissues, so that allowing it to have fireproof and mothproof performance.

Q: Physical and chemical indicators of various refractory.: please read"Refractories Standard Series" for refernece, general business standards are higher than the national standard.

Q: I know which material is the fire resistance rolling shutter door: Inorganic fiber cloth as curtain side replace steel fire shutter curtain of steel plate, the thickness of the inorganic fiber cloth is much thinner than the steel curtain plate and the density is very small, so the volume of the same area of ??the inorganic fiber is super fire shutter the same area of ??steel fire shutter half, and weighs only one more out of the same area a few steel fire shutter, however, the inorganic fiber super fire shutter fire but has a very good insulation properties. I hope my answers are helpful to you.

Q: Refractory factory grinding brick dust harmful to the body?: The effect is very large and belongs to lung disease.

Q: What crusher is used for raw material of broken refractory material? What is the rough crushing process? What are the materials? Thank you!: What is said above ia wrong. Crusher choosed by general refractory material factory is roller type, for example: Roll crusher,teeth-roller?cracker. Choose different crushing equipment according to your requirements. You can go "Zhengzhou Keda Machinery Co., Ltd." to inspect! ! ---Hope it is helpful to you!

Q: What kinds of fireproof materials does the safe use?: The fireproof materials of the safe, cement foam. It is often said recently that the safes with cement inside are bad. Actually, it is not like this. Chemical means are taken to make the cement inside safes rise like a leaven dough so as to achieve good insulation. The principle is the cement foam. Fireproof safes with such techniques have good performance in terms of fireproofing and anti-theft. The manufacturing processes of this fireproof safe are highly technical, some safes with poor techniques have problems in quality. Here are some data of the foam cement.

Q: what's the materials of fireproof?housing?: Prefabricated houses take rock wool board as its wall materials to ensure prefabricated houses and color steel mobile home reach A-class fireproofing standards.
