Q: How to use fire-resistant soil?: In fact, the refractory soil is not strong. Refractory soil is clinker, there is no strength, also known as "blade mud", he is used as filling materials, the use of thickness generally not more than 3mm. Therefore, the furnace insulation can not be done.Civil boiler interior insulation, you can use "high aluminum cement", also known as refractory cement on it.

Q: how about the performance of aluminum silicate fire proof thermal insulation?: aluminum silicate fire proof thermal insulation board has a good performance. it is a artificial board that separates the wood and plant fiber by mechanical and chemical methods and mixed the adhesion agent and water-proofing?agent, molding by high temperature and high press. MDF(medium density fibre board) structure is more even than natural wood. it avoids rot, moth-eaten and other problems, while medium density fiber board has small expansion and contraction, which is easy to be processed. Since the surface of medium density fibre board is smooth, the board is easy to paste a variety of finishings, which makes furniture more beautiful. A variety of decorative wood-based panel is to embellish their homes.

Q: What refractories have good mechanical property resistance and heat expansion and cold contraction property?: Aluminium oxide ceramics. I would like to know that what kinds of refractory materials can combine together and what kind of masonry way can be used for these materials so as to achieve the perfect combination.

Q: What kind of refractory materials should be used for the intermediate frequency furnace to smelt manganese?: I am not quite clear. But you should take two aspects into consideration, namely, no pollution and strong durability.

Q: Why do magnesium oxide refractory bricks can be made into refractories?: The substance used in refractories must have the following characteristics and properties: 1, High stability: Anti-oxidation, anti-reduction and thermal decomposition; 2, High melting point of 2800 degree; 3, Low price. The magnesium oxide refractories have all these three characteristics and properties, particularlly in the aspects of melting point and stability .

Q: What is required to do refractory material?: What kind of refractory material? It’s too extensive.

Q: Does anyone know the fire endurance of steel stud partition?: The fire endurance degree is 1 hour. which is in line with the national building material fireproofing test standards. CaSo4.2H2O is molecular gypsum molecular structure formula, containing 20% ??water, crystal water and free water, when putting on fire, 10% of the surface water will slowly evaporate, remaining10% of crystal water. It is a class A fire retardant material itself. The longest time can be 4 hours.

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: Who knows about the B-level fireproof insulation materials?: Organics, extruded sheet, polyphenyl board and phenolic resin. The fireproof?performance of sea capacity module (fireproof and thermal insulation material) is B1-level with the heat conductivity coefficient of only 0.028w / m · k. It is a good choice. A-level: Rock wool, glass wool, silicate, aluminum silicate, calcium silicate, phenolic aldehyde, and foam glass. B-level: Rubber and plastic, extrusion molding, polyphenyl, PEF.

Q: What are the uses of refractory materials of glass furnace?: crown--high-purity silica bricks; wall--melting end 41# fused zirconia corundum bricks with no shrinkages(41% of zirconium, similarly hereinafter), cooling end 33# fused zirconia corundum bricks with no shrinkages; bottom--33# fused zirconia corundum bricks(with shrinkages); breastwork--33# fused zirconia corundum bricks(with shrinkages); port--33# fused zirconia corundum bricks(with shrinkages); regenerator chamber--the upper part is for magnesite-chrome bricks, the bottom part is for high-duty fireclay bricks; checker--the upper part is for high purity magnesia bricks, and the bottom part is for magnesite-chrome bricks; flue--clay bricks. This is the best configuration. If the funds are limited, the configuration can be lowered, for example, the wall will be changed to 38 #......
