$High Strength Abrasion Resistant Refractory Castable$

Q: What's the texture of refractory for the hearth of reverberatory?furnace? ?: High alumina brick; you can use zircon brick under the temperature above 1700? ;may i use mullite bricks under the temperature from 1400 to 1700? you can use clay brick and heavy corundum brick under the temperature of below 1400 degrees, question closely: what's the usage temperature of reverberatory?furnace? < pre accuse = "qRA" > is there someone use refractory fiber?

Q: Can anyone tell me the requirements of the refractory masonry?？: Refractory materials actually have two functions. The first one is to improve the refractoriness and the second one is to improve the body plasticity of refractory materials.The higher the aluminum content is, the better refractory it will be. Of course, the content of aluminum in refractory materials can not be impoved only by using kaolin. Such raw materials that contain more aluminum as bauxite chamotte should be used as framework.So the content of aluminum in kaolin does not need to be too high and more than 38% of aluminum is enough. However, the viscosity should be taken into account. It will be better if the viscosity is better as the extra bentonite do not need to be added.The refractoriness that is is above 1400 degree is enough.

Q: Application of refractory materials in petroleum industry: For example, natural gas transportation, chemicals, equipment, fillers, safety, insulation, and even building materials for housing are available.

Q: What is the function of refractory in ceramics?: It depends on what purpose you want to achieve. At the same time, part of special ceramics belongs to refractory. If is is to produce ceramic products, the aforesaid answers are very comprehensive.

Q: Which refractory quality inspection authority is good?: Download refractory quality inspection LIRR in Henan is nationally recognized. Of course, it is an authority, but the cost is very high.

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 's the highest temperature can magnesium plate glass resist ?: Glass magnesium plate (commonly known as magnesium oxide or glass magnesium plate) is a magnesium jointing material with stable performance made by adding modifier and processing ternary system composed of magnesium oxide, magnesium chloride. It is a new non-combustible decorative materials comprounded by moderately alkaline fiberglass net as enhanced material and lightweight material as filler. 1, Applications Wall panels, ceiling panels, fire-resistance boards, water-proof boards, boxes, etc.. It can replace wooden plywood panel and be made into dado, door panels, furniture, etc., or into distemper paint water paint to one's need, and can akso be processed into various types of plate surface. It is also applicable to projects undertaken in damp environment such as basement, civil air defense, mines. It can be comprounded with a variety of thermal insulation materials into compround thermal insulation materials 2, Product features: Magnesium plate glass is high temperature resistant, sound absorbing, and capable of preventing water, pests, dampness, corrosion, poison, pollution. Paint can directly be applied to the surface of the plate. Air nails are usable for the plate, to which ceramic tile can also be applied with good pigmentation High strength, flexibility when bending, convenient for decoration. It can be sawed, nailed, and glued. 3, the use of glass magnesium plate: Glass magnesium board is a basic intermediate materials Main occasions for applications: HPL Series: Top of the tunnel ceiling. Decorative plate series: Decoration in hotels, office buildings, residential buildings Board series: Ceiling, partitions, fire proof doors and other products. Sound-absorbing panels: Subway, railway stations, theaters, factories and other public buildings.

Q: can slag tailings be used to be the base materials of refractory materials ?: the rest of it can be used as refractory additives. the scale currently used clay bricks to make high-temperature liquid. It is easy to produce large amounts of liquid because of the high iron content, instead of its refractoriness. But it can be used as refractory minaralizer.

Q: Are there any differences between insulation and refractory materials ?: Refractory materials can resist more than 1200 degrees, some of which are not insulation materials, such as firebricks, which can directly contact with heat source, has little insulation effect. Ceramic fiber, high silica, etc. are all refractory materials which can insulate. Insulation materials with poor performance usually is lower than 800 degrees, which have large thermal resistance, and low thermal conductivity, high porosity. Thus they reduce the thermal loss. To put it simply, insulation materials store most of the heat and only let a small part of heat lose through the air, thus the heat has been isolated. Glass fiber, rock wool, flexible material for thermal insulation, etc.

Q: How to divide fire resistant level of fire door?: The classification of fire resistant level of fire door: Grade A is not less than 1.2h. Grade B is not less than 0.9h. Grade C is not less than 0.6h. It is suitable for fire door with different levels: Grade A: Equipment room (such as fire-pump room,power distribution room, generator room, smoke control fan room, etc) door, fire?compartment, door on firewall; Grade B: Eclosed staircase, front door of stair room, smoke-proof?staircase and fire elevator share lobby door, front door of fire elevator, household door which directly opens to front room or shares room; Grade C: The vertical shaft door, such as strong electric wells, weak electric wells, pipe shaft door and air conditioning facilities.
