Black Silicon Carbide is brittle and sharp and has electrical and heat conductivity in some degree. Aplications : Black Silicon Carbide is suitable for make grinding wheels, cutting wheels, mounted wheels, oil stone, abrasive media, and also suitable for surface grinding, lapping or polishing. The abrasive products made of it are suitable for working on Cast Iron, Non-ferrous Metal, Rock, Leather, Rubber, Wood, Ceramic, etc. Black Silicon Carbide is also broadly used as high-grade refractory material and metallurgical additive.

Q: hat kind of fire retardant materials are there: fire-retardant materials include phosphorus chlorine, bromine and antimony, aluminum, boron based flame retardant, nanometer magnesium hydroxide, high purity industrial grade magnesium hydroxide flame retardant, high purity industrial grade modified magnesium hydroxide flame retardant, composite flame retardant magnesium hydroxide, aluminum hydroxide flame retardant, modified aluminum hydroxide flame retardant, light magnesium-oxide, unsaturated resin flame retardant, silicone rubber flame retardant, polyamide flame retardant, PE flame retardant, PP Flame Retardant, PVC flame retardant, wood flame retardant, special flame retardant for paper, CPE flame retardant, fabric coating rubber flame retardant, flame retardant carpet adhesive, water based coating flame retardant, oily coating flame retardant, power coating flame retardant, ink flame retardant, and heat stabilizer.

Q: Who knows the fire rating of fire?partition with steel stud?: Cement board wall of steel stud: it is used for walls with ceramic in kitchens, restroom, disinfect room, etc. If single-sided tile is made, cement pressure plate can be used on one side. Gypsum board is used on the other side. Fire?rating is A1. CaSo4.2H2O is molecular structural formula of gypsum which contains 20% water, crystal water and free water. When 10% water slowly evaporates on the flame surface, there is still 10% crystal water. Itself is grade A fire retardant material. 1 hour. It is in line with the fireproof test standard of national building materials. It can reach up to 4 hours at most.

Q: Which schools are the best schools in the world for learning knowledge about refractories?: If you search on a worldwide scale, I might say you are ambitious!!! This major becomes an unpopular one and you must have to embark on graduate and PhD to specialize in it provided that you want to go abroad for further study. Wuhan University of Science and Technology may be the best school in this field with its close relatinship with many refractory manufacture factories across the country. Henan University of Science and Technology is also advisable in terms of this major, which probably promise you a job. Other universities in this regard are not quite familiar to me. You raised these questions, which shows that you are a layman to this major or not quite familiar with this major. If you have any questions, you can resort to me if I can.

Q: What are the requirements for the performance of refractory materials?: Electric furnace bottom and furnace slope and the wield pool should be magnesia whole knotting, magnesia carbon brick and tar magnesia brick; hot and slag line area, using high-quality magnesia-carbon brick; Brick on both sides of the furnance door should be tapping El magnesia brick, magnesite chrome brick; electric furnace cover should be high alumina brick and high alumina bricks.

Q: How to choose construction external wall thermal insulation and fireproofing materials?: Now external wall insulation decoration one board is more popular thermal insulation material. Low-carbon energy-saving insulation decoration board combine two constructions (decoration, insulation) into one, saving nearly ten processes,and construction period. Compared with conventional thermal insulation methods, it can increase construction efficiency one time by shortening 60% of the construction period. It integrates low carbon, energy conservation, decoration, fireproof and building aesthetic effect by combining like-dissolving-like binding system installation and bump fixed system, and under long-term cooperation of air handling system and waterproof system. It has excellent outdoor weather resistance, colour?retention, alkali?resistance, water resistance, scrubbing resistance, crack resistance and temperature change resistance, wear resistance, collion resistance and the paint film is firm and durable, with strong adhesive force and mould proof effect. It can provide all-dimensional thermal insulation, decoration, low carbon and energy conservation and fire prevention for construction projects.

Q: how does the fire endurance of first rate fire resistant window?: class A window not less than 1.5 hours, class B window not less than 1 hours, Class C window not less than 0.5 hours.

Q: What are the requirements on fire resistance period of C-level fireproof glass?: What are the requirements on fire resistance period of Class C fireproof glass? The fireproof glass is a special glass which can maintain its integrity and insulation in required fire resistance tests, it can be classified into three types: Class A the fireproof glass which meet demands of fire integrity, and fire insulation at the same time. This glass has advantages of excellent transmittance, fire-proofing(smoke resistance, fire insulation, and blocking heat radiation), sound insulation and impact resistance. It can be applied to architectural ornaments, fire resistant timber doorsets with steel structure, windows, upper beam, partition walls, daylighting roofs, ceiling screens, perspective floor and other building components which need transparency and fireproofing. Class B: The fireproof glass which meets demands of fire integrity and thermal radiation intensity at the same time. This glass is mostly composite fireproof glass which has advantages of transmittance, fireproofing, and smoke resistance. Class C: The fireproof glass which only meets demand of fire integrity. This glass has advantages of transmittance, fireproofing, smoke resistance and high intensity. It can be applied to fireproof glass partition walls, fire windows and with no requirements on outdoor curtain walls, etc. The fireproof glass can be classified as composite fireproof glass and single chip fire-proof glass in terms of structure.

Q: Pals who know something about fire resistant material please tell me how many types of refractory material there are: Classified into ordinary and special refractories. The ordinary refractory material is calssified into acid, neutral and alkaline according to the chemical property. Special refractory material is calssified into high temperature oxide according to the composition for , infusible compound and high temperature composite in addition, can be divided into ordinary refractory products according to the fire intensity (1580 ~ 1770 DEG C), high-grade refractory products (1770 ~ 2000 DEG C) and special refractory products (2000 DEG C above). According to the products shape can be divided into bulk (standard brick, special-shaped brick block, special shape (crucible, sagger, pipe, etc), fibrous shape (silicates of aluminum and zirconium oxide and boron carbide matter) and irregular shape (fireclay, refractory castables and incompletely material).

Q: Who knows what material is in the center of fireproof rolling curtain?: made of inorganic super fireproof rolling curtain: Glass fiber cloth ceramic fiber cloth (reinforced stainless steel wire) ceramic fiber blanket aluminum foil cloth. Hope my answer will help you.

Q: What needs to be paid attention to in the construction of high- temperature refractory mortar?: As far as I'm concerned, in the construction of high-temperature refractory mortar, these matters should be noted: 1. During the use of high-temperature daub masonry stove, the minimum mortar joint should be 0.5mm and general mortar joint should be 3-5mm, which can solve the processing and fine grinding of refractory brick on the brick grinder. Besides, it is conducive to the health of workers, and can reduce the masonry effort, ensure the quality and speed up the construction progress. 2. When making urgent repair on the stove, if the joint is much too large, 2-3mm refractory pieces can be appropriately added into the high- temperature refractory mortar, and stirred to fill the joint so as to shorten the repair time and ensure normal production. 3. High- temperature refractory mortar can be painted inside various furnace body, and it should be guaranteed that the surface of the furnace body has no dust or debris before painting.
