SandBlast pipe is a commonly used hose in the industry, but do you really know how the blast pipe works? Now as a professional sandblasting pipe manufacturer, I will introduce the working principle of sandblasting pipe.
Sand blasting and rust removal by blasting tube uses compressed air as the power to form a high-speed spray beam to spray the blasting material (copper ore sand, quartz sand, corundum, iron sand, Hainan sand) at high speed on the surface of the workpiece to be processed, The appearance or shape of the outer surface changes. Due to the impact and cutting action of the abrasive on the surface of the workpiece, the surface of the workpiece has a certain degree of cleanliness and different roughness, and the mechanical properties of the surface of the workpiece are improved, thus improving the resistance of the workpiece. Fatigue, which increases the adhesion between it and the coating, prolongs the durability of the coating film, and is also conducive to the leveling and decoration of the coating.
1. Workpiece coating and sandblasting before workpiece bonding can remove all dirt such as rust on the surface of the workpiece, and establish a very important basic pattern on the surface of the workpiece (the so-called matte surface). Change the abrasives with different particle sizes, such as Feihan abrasives to achieve different degrees of roughness, greatly improving the binding force of the workpiece with coatings and plating materials. Or make the adhesive bond more firm and better quality.
2. Cleaning and polishing of the rough surface of the casting and the workpiece after heat treatment can clean all the dirt (such as scale, oil and other residues) on the surface of the casting and forging, the workpiece after heat treatment, and polish the workpiece surface to improve the finish of the workpiece. It can expose the workpiece to a uniform metal quality, making the appearance of the workpiece more beautiful and attractive.
3, burr cleaning and surface beautification of machined parts can clean the tiny burr on the surface of the workpiece, and make the surface of the workpiece more flat, eliminate the harm of burr, and improve the grade of the workpiece. And sandblasting can make small rounded corners at the interface of the workpiece surface, making the workpiece more beautiful and more precise.
4. Improving the mechanical properties of parts After sandblasting, mechanical parts can produce uniform and fine uneven surfaces on the surface of the parts, so that the lubricating oil is stored, thereby improving the lubrication conditions, reducing noise and increasing the service life of the machine.
5, light decoration effect For some special-purpose workpieces, sandblasting can achieve different reflections or matt. Such as the grinding of stainless steel workpieces, plastics, polishing of jade, matt surface of wooden furniture, patterns on the surface of frosted glass, and the surface of the cloth.
