Q:Are the specification of fireclay bricks and ordinary clay brick the same?
Do you want to know whether the specifications of fireclay bricks and ordinary clay brick are the same?
Q:What's the function of aluminium dihydrogen phosphate on the refractories?
Mainly used for binder of high-temperature furnace refractory. Characteristics of liquid aluminum dihydrogen phosphate, castable. solid used for refractory spraying coating, chamotte, ceramic construction, which has high break resistance after being dried in 350-500 ° C, phosphate bricks. Characteristics of the solid aluminum dihydrogen phosphate, binding agent used for castable and casting industry: together with the refractory aggregate, ramming mixes at room temperature: Easy to mix, crush resistance, hydration resistance, chamotte, will not become soft even if soaked or boiling in water, molding. Liquid use refractory spraying coating, mainly used for corundum, chrome corundum water gap in refractory industry. The production of chrome aluminum zirconium corundum brick for water-coal-slurry gasifier is especially suitable for site construction applications mainly used for the electrical industry, high-temperature kiln and furnace, hardener, after mixing between 90-110 ° C for 4-24 hours at a constant temperature, forming strong bonding strength, electrical insulation, heat treatment resistance furnace
Q:what's the fire endurance of fireproof panel?
non-asbestos calcium silicate board, fireproof panel partition will excced over 4 hours, two single 75 keel. 12 mm fireproofing calcium silicate board partition, through the monitoring of national fireproof construction materials quality supervision center, it's security and refractory time will reach over 4 hours.
Q:what are the types of piping insulation material fire rating?
There are two grades: 1, the organic material: Grade B Grade B1 hard combustion (fire retardant) 2, inorganic materials: class A no burning it is divided into three levels, attributed to the types of materials!
Q:how long is the fire endurance of plasterboard?
Plasterboard is non-flammable B1 level products. There are introductions in Fireproof Specification of National Standard Building Interior Decoration Design. Plaster board mounted on steel stud can be used as A level decoration materials. In accordance with the national fire safety rules on fire durance of walls and ceilings and other components, we can not simply say whether a piece of gypsum board can meet the requirements. In GB "gypsum board" it clearly states: Fireproof plasterboard can endure fire longer than 20minutes. Wherein Dragon brand fire-resistant gypsum board can endure fire longer than 40 mintues. Gypsum board is comprised of dry wall, steel stud and various auxiliary materials. the fireproof performance of the gypsum board system is relevant to the type, quality , layers of the gypsum board, quality of keel and installations, whether the rock wool is filled and its unit weight, the treatment of seaming and some minor joints.
Q:Which refractory is better for building 1500 degree kiln ?
High alumina brick or 99 alumina hollow ball brick is OK, which can withstand a temperature of 1600 ℃.
Q:Do you know where I can buy refractories?
You can buy refractories in these places: 1. Addresses of refractory factory: No. 57, Qingshan District, Wuhan 2. Address of Qingshan refractory factory in Wuhan: Special NO.1 Xingli Road Hongshan District, Wuhan 3. Address of Xinghuo refractory factory in Hongshan district: No. 34 Qingshan District, Wuhan 4. Address of Henao refractory factory: No. 78 Jiangxia District, Wuhan
Q:which kind of refractory is commonly used in the industry
Like silicon, magnesium calcium and metallurgy refractories, glass, silicon, etc., knowing the basic materials, and the businesses are not the same. I suggest that you can buy the refractory book to read.. Others include zircon, shapeless refractory material and so many other cement, such as magnesia, high alumina,ect.. Iron making is using the acidity material, continuous casting is using the clay, nonferrous metals and other types of more complex hot-press charcoal; steel making is using the alkaline, magnesium chrome, magnesium carbon, and clay,etc..
Q:What is the criterion of entry of refractory clay industry?
Standard sizes of refractory bricks in our country are: 230mm × 114mm × 65mm; ordinary brick: 240 * 115 * 53, Building blocks: (blind holes, through-holes) 240 * 390 * 190 * 190,240 * 190,240 * 190,190 * 90 * 190 * 390 * 190,190 * 190,190 * 190,190 * 190 * 90 * 190, 140 * 390 * 190,140 * 190,990 * 190 * 200 * 400, from 0 * 390 * 190 * 190,90 * 190,90 * 90 * 190. There is also an interlocked hollow blocks: 90 * 200 * 200 * 400,90 * 245,90 * 200,90 * 200 * 200 * 100, 90 * 200 * 290,150 * 275,150 * 200 * 200 * 200, 150 * 200 * 100, 150 * 200 * 290.
Q:what is steel fire door made of ?
1. fire resistance steel door has steel made door frames, door leaf framework and door panels. if the door leaf is filled with nontoxic fire insulation material, added with fireproof hardware accessories, which consists of a door that is fire resistance. This is a steel door.
