Abrasives Raw Material Green Silicon Carbide/Carborundum grit particle
1. Description:
Green silicon carbide is produced in the same way as Black silicon Carbide
except for some differences in raw material. Silicon carbide is an extremely hard
material (Mohs hardness 9.4), is chemically inert and does not melt. Silicon Carbide
has a high thermal conductivity, a low coefficient of thermal expansion, is thermal
shock and abrasion resistant and has strength at high temperatures.

- Q: Who knows about the fire endurance of A grade fireproofing glass doors?
- Fire doors and windows are divided into grade A, B and C according to the real national situation, also the minimum fire endurance has been stipulated, namely, the minimum fire endurance of grade A is 1.50 h, that of grade B and C are 1.00 h and 0.50 h respectively. There are wooden fire doors and steel fire doors. The main purpose of it is to reach the time that fire resistance should last. But door?closers are required to install. The fire endurance of A grade wooden fire doors should be no less than 90 min, and that of B grade fire doors should be no less than 60 min, that of C grade fire doors should be no less than 30 min! ! !
- Q: What is the role of adding chromium oxide green in unshaped refractory materials
- Generally, less is added in corundum or corundum spinel refractory material, but it can significantly improve the material performance such as high temperature strength, erosion resistance, thermal and shock stability, etc.
- Q: which kind of fire?bulkhead is better?
- General business fire endurance of two products are 3 hours. Organic fire bulkhead's main ingredient is organic material, which can be used in anti-corrosion and fireproofing cable tray. Inorganic fire?bulkhead's main ingredient is inorganic material, which mianly play a role of fireproofing. It's main ingredient is inorganic material, so it can't be used in acidproof and alkali resistant projects. Of course, the price of same amount organic fire?bulkhead in general is more expensive than the inorganic fire?bulkhead.
- Q: I want to consult the fire resistant level standards of external wall thermal insulation materials.
- Fire resistant level standards of external wall thermal insulation materials: 1, The thermal insulation material that has A-class combustion performance: Spraying inorganic fiber, glass wool, foam glass, ceramic foam, rock wool, foam cement and perlite obturator, and so on. 2, The thermal insulation material that has B1 level combustion performance: Special processed extruded polystyrene board (XPS) / special processed polyurethane (PU), phenolic and polystyrene powder. 3, Thermal insulation materials that have level B2 combustion performance: Molded polystyrene board (EPS), extruded polystyrene board (XPS), polyurethane (PU), polyethylene (PE), etc.
- Q: What is the function of refractory material?
- Refractory is a basic material in the field of high temperature technology. Generally, the refractory is used as structural material or lining to resist high temperature in various thermal equipment and high temperature container. In the iron and steel industry and metallurgy industry, coke ovens are mainly composed of refractory materials. Various refractories that meet the requirements are essential in blast furnace for ironmaking, hot stove, all kinds of steel-making furnaces, soaking furnace and heating furnace. Not only the die casting for molten steel needs lots of refractory materials, but also the continuous casting needs some high-quality refractory materials. Without high-quality refractory materials, external refining is also not impossible to achieve. Statistics show that the steel industry is the sector that needs the most refractory. Pyrometallurgy and thermal processing of ferrous metal also needs refractories. All high-temperature furnaces or lining in construction materials industry or other high temperature industries that produce silicate products such as glass industry, cement industry, and ceramics industry must be constructed with refractory materials. All kinds of roasting funaces, sintering funaces, heating furnaces, boilers, flues, chimneys and protective layers in chemical, power and machinery manufacturing industry need refractories. In short, when some kind of structures, devices, equipments or vessels are used under high temperature, they all should utilize refractory to resist the high temperature because those materials will deform, soften and fuse or will be eroded, scoured or broken due to the physical, chemical, mechanical effects, which may stop the operation, affect the production, contaminate processed objects and impact the quality of products.
- Q: What kind of fireproof material is used for steel structure?
- Brushing or spraying the coating on the surface of steel structure to prevent burning and insulate heat. It also prevents undermining the rolled steel from rapid temperature elevation and avoid collapse of building for lose of supporting capacities. Agglutination material are classified as fireproof coatings for steel structures which is solvent based and Water-based steel structure fire retardant coatings. Fireproof coatings for steel structures which is solvent based are subdivided into fireproof coatings for steel structures which is solvent based with low benzene content and fireproof coatings for steel structures which is solvent based with high benzene content (TVOC≤600g / L, benzene ≤5g / kg). It can be divided by thickness. ultra-thin (CB) fireproof coatings (coating thickness ≤3mm), thin (B) fireproof coatings (3mm & amp; lt; coating thickness ≤7mm) and thick (H) steel structure fire retardant coating (7 mm & amp; lt; coating thickness ≤45㎜).
- Q: What's the classification of flameproof glass, the refractory time of fireproofing glass.
- there mainly are five fireproofing glasses, the first one is laminated composite fireproof glass, the second one is wired fire-resistant glass, the third one is special fireproofing glass, the fourth one is hollow fireproof glass,the fifth one is high strength monolayer cesium potassium fireproof glass.
- Q: how to classify the fireproofing material levels A1 A2 B1?
- their classification is shown specifically in Fireproof? Specification of Building Interior Decoration?Design GB 50222-95 appendix A, flammability,inflammability materials, flame retardency, noninflammability: combustion performance of A, B3, B2, B1 materials are divided into
- Q: What are fire resistant level standards of class A fire resistant door?
- Grade standards: class A fire resistant door is an important part of fire-fighting apparatus, and an important step in the social fireproof work. The quality and use of class A fire resistant door is closely related to the success or failure of the fireproof work.. There are steel and wood for class A fire resistant door materials. Only those whose fire endurance is no less than 1.5h can be called class A fire resistant door. In general, the class A fire resistant door internal material is perlite, and still some are vermiculite fireproof board, foam core board, MCcomposite materials, and other fireproofing materials. The thickness of class A fire resistant door is usually 50mm. In places where there is strict requirements for fireproof?performance, class A fire resistant door is often installed.
- Q: what is steel fire door made of ?
- 1. fire resistance steel door has steel made door frames, door leaf framework and door panels. if the door leaf is filled with nontoxic fire insulation material, added with fireproof hardware accessories, which consists of a door that is fire resistance.
