What kinds of water knife sand

Abrasive high-pressure water jet cutting technology is a major advancement in cutting technology. Its cold and harmless cutting method has been recognized by many users, with high penetration rate and rapid development. As a secondary cutting abrasive, waterjet sand plays an important role in cutting operations. When it comes to waterjet sand, the first thing that users think of is garnet. What types of waterjet sand are there. Only garnet can be used as waterjet sand? Rizhao City Garnet Mining Co., Ltd., as a large manufacturer of garnet water-jet sand in China, today explained why garnet is widely used in waterjet cutting. In the early days, quartz sand was also used as waterjet sand. Its Mohs hardness is between 5.5-6.5, garnet water-jet sand hardness is between 7.0-8.0, quartz sand is inferior to garnet in abrasion resistance and cutting ability, same cutting material, garnet water-jet sand The cutting speed is much faster than that of quartz sand, cutting effect is better, speed is faster, and the material is more provincial. The garnet waterjet cutting material is almost no need for secondary sanding, so the use of quartz sand as a waterjet sand is almost replaced by garnet, but quartz sand is thrown into use by a very small number of people. Used to cut soft plastic products. The hardness of brown corundum is above 9.0, and it has also been used as waterjet sand, cutting faster and cutting time shorter. However, there is an old saying in China that it must be reversed. Due to the excessive hardness of brown corundum, the wear of sand tubes is very strong. The service life of sand tubes is often only 30 to 40 hours, and the use of high-quality, non-plugged pomegranates Stone water knife sand, sand tube life can reach more than 200 hours. Therefore, brown corundum is replaced by garnet water knife sand. Nowadays, the common use of brown fused alumina is to use it as a refractory material and a wear-resistant material. The garnet waterjet sand has been recognized by waterjet users due to its moderate hardness. The high-quality garnet water-jet knife sand is dark red in color, and the particles are clean and dust-free, and the particle concentration is high, and no plug-in phenomenon occurs. When you consider the above points at the time of purchase, the more likely you are to buy a high quality waterjet sand.
