黑碳化硅砂防滑砂20目直径1mm

黑碳化硅砂防滑砂20目直径1mm是一种硬度很高的材料。黑碳化硅是由天然硅石和石油焦，添加食盐等辅料在大型电阻炉中经2300°高温冶炼得到的人工合成材料。他的维氏硬度为2800-3200HV，显微硬度为28-33GPa损能力很强。黑碳化硅还具有很好的耐高温稳定性、耐低温稳定性、耐候性老化、耐腐蚀、膨胀系数小变形、绝缘性的特点。加入PU、塑料、树脂等材料中，可以增加材料的防滑裂性能。

Black silicon carbide anti-skid grain is a wear resistance aregate with high hardness. Black silicon carbide is an artificially synthesized material fromelting natural silica and petroleum coke with additives such as salt in a large resistance furnace at 2300 ° C. His Vickers hardness is 2800-3200HV, and hiicro hardness is 28-33GPa with strong damage resistance. Black silicon carbide (black carborundum) also has good high-temperature stability, low-temperature stability, weather resistance, aging resistance, corrosion resistanceall expansion coefficienformation, and insulation characteristics. Adding materials such as PU, plastic, and resin can increase the anti-cracking performance of the material.

黑碳化硅砂防滑砂20目直径1mm的特性：

1. 高温化学稳定性和耐腐蚀性能强：碳化硅在1000°以下温度环境中性能十分稳定，1000°以上稳定下碳化硅的表面形成一层二氧化硅薄膜，仍然可保持碳化硅理化性能稳定。温度达到1627°以上，碳化硅的能力才会下降。
2. 导热性能优越：常温下碳化硅的导热系数为60-200 W/(M·K)。纯碳化硅的理论导热系数（热导率）为490 W/(M·K)，比大部分钢铁、铜和铝的导热系数还高。制成的碳化硅陶瓷件的导热系数为120-170 W/(M·K)。具有良好的热传导性能。
3. 碳化硅具有较低的热膨胀系数和热震性能：较低的热膨胀系数：25-1400摄氏度温度下，碳化硅的平均热膨胀系数为4.4x10^-6/℃，低于氧化铝质的耐火材料。
4. 高硬度、韧性和高性：黑色碳化硅莫氏硬度为9.2-9.3，绿色碳化硅莫氏硬度为9.4-9.5，维氏硬度为3100-3400kg/mm2。碳化硅的硬度还会随着温度的增加有所降低，在1200度高温状态下，碳化硅的硬度能达到刚玉的2倍。
5. 高韧性：碳化硅磨料的韧性是指在外力作用下碎的难易程度，以46目为例，静压法测试的韧性大概为68-78%。碳化硅的机械强度高于刚玉，以120目粒度为例，碳化硅的压强度为186KN/cm2，刚玉磨料的压强度为100KN/cm2。
6. 粒度均匀：颗粒大小范围窄，具有良好的流动性和分散性。
7. 清洁度高，游离碳含量低，杂质少。

1. High strength and strong wear resistance. The Mohs hardness of black silicon carbide is 9.15-9.2, and the Vickers hardness at room temperature is HV3100-3200kg/cm3. Even at a high temperature of 1000 ° C, the Vickers hardnesan reach 1300-1400kg/cm3. The Mohs hardness of quartz sand is 7, garnet is 8-8.5, and corundum is 9.0, both of which are lower than that of silicon carbide. The hardness of silicon carbide is only slightly lower than that of boron carbide and lower than that of diamond.
2. High compressive strength and crushing resistance. The compressive strength of a single particle of first-class black silicon carbide is 186 KN/cm2, and theerage crushing strength of silicon carbide with particle sizes of 90-2500um is 5800 KPa/cm2. It can withstand the crushing of vehicles and hey objects.
3. Black silicon carbide has a high refractory temperature. Black silicon carbide has a melting poif 2600 ° and maintains high strength and stable performance at high temperatures. Hing a high level of fire protection.
4. Silicon carbide has strong corrosion resistance. It does not react with acids or bases. Therefore, it can be used as a flooring material for special places such as laboratories.
5. There are numerourticle sizesailable for black silicon carbide. The black silicon carbide specificatiproduced by Haixu Abrasive cover powders ranging from 1-3mm sand to 3.5 micr. Users and ctruction parties can freely choose according to their needs.
