F16 F24 F30 F36 F220 F2000 Green silicon carbide for Abrasive

 Green silicon carbide grit is a very hard abrasive material . The hardness of it only ranks after diamond and B4C, and it is harder than black silicon carbide. So it is suitable to grinding large range of hard material such as titanium alloy, marble, carbide alloy, optical glasses, ceramics, etc. Green Silicon Carbide is produced at high temperature in an electric resistance type furnace with quarts sand and petroleum coke. The SiC purity of green silicon carbide is up to 99%min. It is an artificial brittle SiC with high thermal conductivity and high strength which get no decrease in 1000 centigrade.

How to improve the durability of silica fume concrete?

Image
  There are many factors to measure the quality of concrete performance, durability is one of the very important indicators, if the durability is not enough, will lead to serious consequences. Thus, in the concrete configuration, how to improve the durability of concrete is a problem that engineers have been thinking about, the following we will understand some of the factors that affect the durability of concrete. The use of high-grade cement There are many factors that affect the durability of  concrete , not only the impact of the concrete configuration process of adulterated substances, but also need to pay attention to the quality of cement, such as the strength of the cement in the configuration process, varieties, aggregates and other factors of its own. In the actual project, we should consider the specific situation, and through scientific testing, so that the concrete to achieve the required high strength, high durability and high fluidity. The preparation of high-st...

From Waste to Wonder: The Remarkable Journey of Silica Fume in Industry

Image
Introduction to Silica Fume Origin of Silica Fume Silica fume, also known as microsilica, is a byproduct of the industrial production of ferrosilicon and silicon metal alloys. It's a fine powder composed primarily of silica (SiO2) and forms when silicon and oxygen react at high temperatures. Originally considered a waste material, silica fume has since been recognized as a valuable resource for various industries. Properties of Silica Fume Silica fume possesses unique properties that make it particularly useful in industrial applications. It is a highly reactive pozzolan, which means it can form cementitious compounds when mixed with water and calcium hydroxide. It also has a very fine particle size, usually less than 1 micron, giving it a large surface area that helps improve bonding and packing in composite materials. How Silica Fume is Produced Collection and Processing During the production of silicon metal and ferrosilicon alloys, silica fume is generated as a byproduct in th...
