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.
2. Sizes:
Grits: F#8, F#10, F#12, F#16, F#24, F#30, F#36, F#40, F#46, F#54, F#60,
F#70, F#80, F#90, F#100, F#120, F#150, F#180, F#220

- Q: How long is the duration of fire resistance of autoclaved flyash-lime bricks?
- The fly ash effect will continue to play a role in a considerable period of time, so the long-term strength keeps strengthening, the average age of 90 days of strength will grow 80%-100% more than the 28 days.
- Q: How many kinds of fireproof materials are there in the market?
- I wonder that how many kinds of fireproof materials are there? Does anyone know about it, please tell me, thanks
- Q: What's the fire endurance of hollow brick?
- This question is really very simple. It is better no to exceed 1050℃, or it will be easily burnt. I think 980℃ is ok actually. This is the maximum limit.
- Q: What is the use of refractory?
- It is used as a protective layer inside the high-temperature, high-corrosion, high-washing, easy to be wore equipment and as an insulation layer outside equipment.
- Q: Does anyone know about the classification standards of B2-level fireproof and thermal insulation materials?
- 1.The insulation materials with A-level combustion performance: EPS Hairong module, rock wool, glass wool, foam glass, ceramic foam, foam cement, closed-cell perlite, etc. 2. The insulation materials with B1-level combustion performance: specially-treated extruded polystyrene boards(XPS)/ specially-treated Polyurethane(PU), Phenolics, Polystyrene rubber powder particles,etc. 3. The insulation materials with B2-level combustion performance: Expanded polystyrene sheets(EPS), Extruded polystyrene boards(XPS), Polyurethane(PU), Polyethylene(PE), etc. See the 2009 measures of building technology. The A-level insulation material is only fireproof, the insulation performance of it is worse than that of organic XPS \\\\ EPS material. Currently I think that the best insulation material should be Hairong EPS module, it not only achieves the requirement of insulation but also fulfills the goal of fireproofing, and the comprehensive unit price of it is not expensive. The insulation materials in the domestic market have their own disadvantages, you'd better take the building demands into consideration, and use the materials that are within the acceptable range.
- Q: Refractories for iron-making blast furnace?
- Cement kilns?
- Q: What are the classifications of refractory? Which category does steel ladle castable belong to?
- In addition, it can be divided into refractory, shapeless refractory material. And it can also be divided into acidic refractory, basic refractory and neutral refractory. If you want to know more, you can ask thme. In fact, every company has different refractory clasifications. There are more clasifications in Huaheng.
- Q: What is the interior fireproof thermal insulation material?
- The methods of thermal insulation wall have three kinds of materials. First: gypsum board or cement board are stuck outside the polyphenyl board; second: lightweight brick build; third: infill polyphenyl board, lightweight brick is built outside. The first two has almost the same price. The latter is slightly expensive. 60 yuan / square meter is not very expensive!
- Q: What are the types of steel refractory materials
- The major category is classified as permanent layer, working lining. Specific varieties: Air permeable brick (corundum). steel ladle brick (magnesia or corundum), permanent layer castable (high alumina), reinforcing material for ladle bottom, repair material for the edge of tank and so on.
