Q:What are the raw materials of refractory?
Refractory is mainly resistant to high temperature and fire. Sic refractories are widely used in refractory. I hope my answer will be helpful to you.
Q:What is the the best matching ratio of refractory cement?
Refractory cement is very easy to use. Add some water and mix, and it will harden. Generally there is no need to add other binding agents, but you can add some refractory aggregate and powder. If you use only refractory cement, it will produce a lot of cracks after high temperature. Generally refractory cement can withstand temperature of about 1300 degrees. Refractory cement can be used together with ordinary sand, and the ratio of cement and the sand is about 30 percent.
Q:What's the A class fireproof and thermal inuslation matertial for external wall?
It is a kind of green and environmental protection inorganic material, free of harmful substances like asbestos, benzene, formaldehyde, etc. Its fire resistance can be up to A1grade non-combustible material, which means it can endure the highest temperature of 1400 ℃. It is thermal insulating with low heat conductivity and high heat storage coefficient. It has good weather resistance, finished product stability, anti hollowing, crack resistance, wind pressure and shock resistance with the same service life as buildings of 70 years. It is water-fast and moistureproof, breathable but waterproof, and fungusproof without influence from steam. It is convenient in construction which omits many procedures of panels construction. Once the second plastering is finished, the construction is completed, which greatly shortens the construction period. It has good adhesive property with various base planes, and meanwhile its external exposed surface can choose coating, facing brick, aluminum sheet, marble, etc. It saves money. Excellent construction technology reduces the construction cost. It effectively prevents the panels from leakage at the external wall, window, eave, etc. which saves the subsequent maintenance fund. It provides timely delivery. With sufficient supplies of raw materials and convenient production, it is fast in delivery.
Q:How to divide the fire rating standards of insulation materials?
The fire rating classification standards of insulation materials, 1. Insulation materials with A-level combustion performance: inorganic fiber spraying, rock wool, glass wool, foam glass, ceramic foam, foam cement, close-celled perlite, etc. 2. Insulation materials with B1-level combustion performance: specially-treated extruded polystyrene boards(XPS)/ specially-treated Polyurethane(PU), Phenolics, Polystyrene rubber powder particles,etc. 3. Insulation materials with B2-level combustion performance: Expanded polystyrene sheets(EPS), Extruded polystyrene board(XPS), Polyurethane(PU), Polyethylene(PE), etc.
Q:What are the specifications of fireclay bricks?
Dimensions of refractory bricks : 230 * 115 * 65mm
Q:What are unshaped fire-resisitance materials?
Refractory castable, refractory plastic material, usually classified according to construction and manufacture method, unfired bricks precast block, refractory pressed into material, refractory cast material, refractory coating, refractory ramming material there are many classification methods
Q:Does the production of refractory belong to advanced technology?
It certainly is advanced technology as it is the new material.
Q:What is the main material of fireproof wooden door?
Fireproof door is an important part of fire-fighting apparatus and society fire prevention, so the quality and use of fireproof door is the key to the success of the fire prevention. Some customers don't know clearly that whether the fireproof door should install a door closer. Today I specially read the explanation of relevant state departments for fireproof door, in the explanation in 5.3.3, fireproof door should be installed fireproof door closer or set, so that normally open fireproof door can automatically close close-door device of the door leaf (except for the use of special parts, such as pipe shaft doors, etc.) in the event of a fire. In other words, except for some special parts which don't need to be installed door closer, such as pipe shaft doors, other parts are required to install fireproof door closer.
Q:What are the requirements of the performances of brasque refractory?
The requirements of the performances of brasque refractory: 1, should have sufficient refractoriness and softening point under a fixed load. Because under the action of the electric arc, the inner and surface temperature of the different parts of the brasque can be up to 1500 ~ 1800 ℃. 2, should have strong slag resistance. Because the inward permeation of slag and smoke at high temperature through its pores of brasque cause melting loss of refractories, organization delamination and flaking. 3, should have good thermal shock resistance. Because in the steelmaking process, opening the furnace door, lifting the furnace lid will cause sudden temperature change of brasque refractory,flaking and cracking, resulting in premature failure of brasque. 4, should have sufficient strength, because the brasque will be impacted at the time of loading, vibrated when tilting, flushed by metal, slag and gas flow when boiling. 5, the thermal conductivity and the conductivity should be small. Refractories commonly used for electric furnace include magnesia bricks, dolomite brick, high-alumina refractory bricks, silicious refractory brick and magnesite ramming material. Due to the different working environment of each parts of the furnace, refractories are different.
Q:What are the requirements of refractory temperature of refractory brick?
Refractoriness can reach 1690 degree, but the highest operating temperature is 1350 degree. If the temperature goes higher, operation life will be greatly shortened.
