Q: Who knows how many fire heat preservation material are there?: There are many kinds of fire proof materials. The major material used in construction industry is fire proof and thermal insulation material, mainly include vitrified micro bead insulation board, class A expanded bead fiber board, rock wool board, plastic extruded sheet, polyurethane insulation board

Q: What's the fire?retardant material of roller shutter fire resistance door ?: I am happy to answer this question. Fire resistant rolling shutter door is generally filled with aluminum silicate fiber cotton inside. fire resistant rolling shutter doors are divided into special inorganic fireproof rolling shutter door and steel fire resistance rolling shutter door. The former has better fireproof?performance, but the later has certain wind load resistance and can be installed outdoors.

Q: What the fireproofing materialare of the refractory kettle and where they can be sold?: Many places sell these. Nearly 10 years, can't brun when it is dry, adsorption. You can also baidu these materials. Heat transfer evenly, feldspar, clay and other raw materials with a ceramic products. Traditional casserole can not resist heat difference and also can withstand for 100 high temperature without crack. Aiming at the problem of traditional casserole, easy to crack and air permeability, people joined the spodumene on raw material, produce a high-temperature resistance casserole. It is produced after the high temperature burning makes an earthenware pot to keep the original advantages. Hebei has many places to sell these materials and is also relatively cheaper. The traditional casserole has features of not easy to transfer heat's quartz and slow cooling. Due to production technology and raw materials, it greatly improves the casserole' practicability after research and improvement.

Q: Would you like to know if there are any enterprises in Mianyang that need fire-resistant materials?: Big business needs to be usedIntroduce several big: Jiuzhou 208827 and Changhong

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: Does anyone know about the A-level fireproof materials?: rock wool external wall composite board, A1-level fire rock wool board, hidden slit rock wool board ? 30, A1-level fireproof mineral wool sound-absorbing board. What about the sound-absorbing sheet? glass fiber acoustic board engineering of the TV backdrop ? 85, A1-level fireproofing and thermal insulation rock wool board is hydrophobic thermal insulation, external wall thermal insulation materials ? 200, high temperature resistant calcium silicate board, LCFC/calcium?silicate?board is A1-level fireproof materials with high-quality and low-price ? 75, the prices above are from the internet for reference only, and the purchase prices vary according to the market.

Q: For refractory, why is it necessary to store the first mixing materials for some time under proper moisture and temperature?: It is mainly to remove gas form chemical reactions in the pug, give full play to plasticity and binding properties of combined, and store unburned?brick whose cememting agent is phosphoric?acid or aluminium?phosphate for some time under proper moisture and temperature. For example, to avoid the formed bricks in the initial stage of drying and firing form cracking due to hydration of calcium oxide. Mixing materials is to store the first mixing materials for some time under proper moisture and temperature in order to improve the evenness and moldability of pud, such as making the distribution of combined clay and water more even. The length of storing chiefly depends on the process requirements and the characteristics of blanks. For the producing pug of high temperature kiln furnitures, the storing time is longer. The function of storing mxing materials varies with different natures of blanks. For honeycomb ceramics, it is to fully digest calcium oxide in blanks. For storing magnesia brick blanks containing much calcium oxide, it should be stored for some time in proper humidity and temperature.

Q: Could you tell me the fire-resisting time of class B fire proof door?: Could you tell me the fire-resisting time of class B fire proof door?

Q: Who knows what fire heat preservation material are there?: Organic material, polystyrene board, plastic extruded board, phenolic resin. Sea capacity module (fire insulation materials fire performance can reach the B1 level, thermal conductivity is only 0.028w\m - K is a good choice, class A fireproof materials now is the mainstream rock wool (mineral wool is wool). A1 fire resistance The largest manufacturer is Thai stone rock wool Co. Ltd.

Q: What are the refractories for converter?: Permanent layer (sintering) magnesia brick, the working lining gunning material for the working layer and the permanent layer gap, using magnesia ramming materials, MgO-C brick brick supply,
