Black Silicon Carbide is made by a precision water classification process and air flow classification using material that is produced from the reaction between high purity silica sand and petroleum coke in a resistance-type furnace. Measuring 9.0+ on the MOHS scale of hardness, silicon carbide is one of the hardest abrasives known in the industry. The inherent friability of the sharp crystalline structure assures the continuous exposure of new cutting edges, which produces a faster and cleaner cutting performance.
Green silicon carbide is produced as the same type as the black silicon carbide,except the different raw materials. It’s crystallization have higher purity and hardness.Green silicon carbide is suitable for processing hard alloy,metallic
and non-metallic material with hard and brittle feature such as copper, brass, aluminum,magnesium,jewel, optical glass, ceramics, etc. Super micro-power of it is also a kind of ceramics material.

- Q: Who knows how many fire heat preservation material are there?
- Fire proof board is a fire refractory building material for surface decoration, widely used in interior decoration, furniture, kitchen cabinets, laboratories mesa, walls and other fields. Fire board is base paper (titanium powder paper, kraft paper) processed by melamine and phenolic resin, high temperature and high pressure. 1 mineral wool board, glass wool board: mineral wool, glass wool insulation. It does not burn itself, have good performance such as high temperature resistance, light quality. Such plate have evolved into plate with inorganic adhesive material as base material, mineral wool, glass wool as reinforcing material plate. 2 cement board: High strength, wide source. In the past, it is used to make fire prevention ceiling and partition wall, but its fire resistance is poor. Cement concrete component has good heat insulation and sound insulation performance. It can be used as the partition wall and the roof panel.
- Q: What's the refractory material?
- According to the product shape, it can be divided into two kinds, that is shaped refractory and unshaped refractory. According to the chemical?property, it can be classified into three categories, that is acid refractory, neutral refractory and basic refractory, among which basic refractory and neutral refractory are commonly used, such as the basic refractory of magnesia carbon brick, fired magnesite brick, magnesite-chrome brick, magnesia-calcium brick, and the neutral refractory of high alumina brick, corundum brick, clay brick. Unshaped refractory includes: castable, ramming mass, gunning mix, coating material, dry vibration material, etc.!
- Q: I know which material is the fire resistance rolling shutter door
- Fire resistance rolling shutter door and ordinary roller shutter are basically same, the differences are: Its inner and outer sides are generally made of galvanized iron sheet, filling asbestos fireproofing material betwwen two layers of fire resistance rolling shutter door, and some fire shutter doors can be interlocked with the relevant fire control system, when the breaking out of fire , it can automatically "half-drop" and "full drop".
- Q: How to classify the grade of wall fireproof and thermal inuslation matertial?
- To sum up three versions of GB8624 (1997, 2006, 2011), fire?rating of external wall thermal insulation can be basically divided into: A1, A2, B1, B2, B3 and other levels. Specific division has many technical indicators to judge. It can't be said for a moment. It is very professional and technical. For details, please contact Qingdao Shanfang Instrument. They specialized in tester of fire?rating of external wall thermal insulation materials.
- Q: What is the most reasonable drying heating curve of magnesia refractories? Products of less than 0.5T
- You'd better oxidize magnesia preformed unit at room temperature for a longer period of time, then bake it, during which, it's enough to control the maximum temperature within 300 degrees. During the middle process, usually heating up for 4 hours and keep warm for 3 hours. The entire heating up process takes about 20 hours. If it is the site operation magnesia-based castable, it should be heated slowly in the early stage, and pay attention to keeping warm at 80 degrees Celsius. Every manufacturers has their own heating curves, so do not blindly adopt existing curves, try to make your own heating curve.
- Q: What is the magnesium carbon refractory?
- The composition of refractory brick raw material There are many types of refractory brick raw materials, mainly divided into six categories: Soil, stone, sand, mineral, power and others. One of the original material, soil: Aluminum, kaolin, clay, diatomaceous earth The second raw material, Stone: fluorite, kyanite, andalusite, forsterite, vermiculite, mullite, pyrophyllite, chlorite, dolomite, sillimanite, magnesia-alumina spinel, silica The third kind of raw material, sand: Pottery, zircon sand, quartz sand, magnesite The fourth kind of raw material, ore: Chrome ore The fifth kind of raw material, powder: Aluminum powder, silica powder, silicon powder The sixth kind of raw material of refractory brick, others: Asphalt, graphite, phenolic resins, perlite, cenosphere, sialon, corundum, silicon sulfate, silicon carbide, sodium silicate, silica solution, boron carbide, calcium aluminate cement, nitride material, shale ceramisite, alumina, alumina sol and zirconia, etc.
- Q: What are the raw materials of refractory?
- Of course, different types have different raw materials: Magnesite (the electric?smelting: alkaline refractory, magnesia-carbon bricks, alkaline, high-purity) + crystalline flake graphite + phenolic resin + additive (silicon powder, aluminite powder, silicon carbide powder, or high-temperature asphalt,etc.) , acidic refractory: The neutral is not easy to answer. such as. You can check out the classification, such as
- Q: What are the differences between first-level fire-resistant materials and second-level fire-resistant materials?
- Level B1: building materials with flame retardancy: this kinds of materials have good effect in flame retardation. Under the case of open fire or high temperature, it is not easy to be ignited and spread quickly, and when the fire source is removed, fire would stop immediately. Level B2: combustible building materials: combustible building materials also have effect in flame retardation. It will get burnt as soon as it meets open fire or high temperature, so it can easily give rise to rampant fire, such as wooden pillars, wood roof trusses and wooden stairs.
- Q: Can polystyrene foam color steel plate be used as decorative fireproofing material ?
- No, only non-combustible product can prevent fire. Most polystyrene foam boards are flammable which cannot prevent fire. Polyphenyl can only retard flame, highest fire?retardant fire?rating being B1 level. Under the same conditions, fireproof performance of polystyrene foam board will be better because most extruded sheets are made by recycling materials and contain much more impurities which will affect flame resisting property. The second reason is that high temperature in extruded sheet manufacturing technique will decompose part of flame retardants. For B1 level extruded sheet, it is difficult to reach 30 burning oxygen index, while for B2 level, it is hard to reach 32. So polyphenyl board is safer.
- Q: What's the fire resistance test method of doors and roller shutters?
- Fire resistance test method of doors and roller shutters: This standard specifies the fire resistance test method for roller shutter doors under standard fire conditions. The method is used to test the fire resistance of the ventilating duct when bearing the external fire (A duct) and internal fire (B duct). Fire resistance test of vertical ducts may be conducted referring to this standard. 1.Test specimen1.1 The test specimen is obtained by cutting from any part of the qualified metal tube unless otherwise relevant standard or mutual agreement specifies the cutting position of the metal tube. 1.2 Length of the specimen: L≈2.5D+50mm (D: outer diameter of the metal tube). The cut surface of the specimen must be perpendicular to the axis of the metal , and the seamed edge of the cut should be round off. Test method GB243-82 of metal tube necking 2. Test procedures 2.1 In the test, punch or press the metal tube into the tapered conical seat (see Figure) with a hammer or press machine, and make it uniformly diminished to the regulated shrinkage X which is calculated according to the following formula: Test method GB243-822 for metallic pipe necking: The inner wall of the seat cover used in the test should be polished, and has certain hardness and is coated with lubricating oil. Its conicity is 1:10, 1:5 or others in accordance with relevant standard provisions. If there is no provision, then adopt the conicity of 1:10. This standard is not suitable for: a) The pipeline whose fire resistance depends on the fire resistance of the ceiling; b) The pipeline with access door, unless otherwise the access door is included into the pipeline and tested together; c) The pipeline with two or three sides; d) Fume exhaust pipes;
