One: The main application scope of sand blasting (one) workpiece blasting and pre-bonding of workpieces. Sand blasting 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 (that is, usually (The so-called matte surface), and you can achieve different degrees of roughness by exchanging abrasives with different particle sizes, such as fly-abrasive abrasives, greatly improving the binding force of the workpiece with coatings and plating materials. Or make the adhesive bond more firm and better quality.
(II) Cleaning and polishing of the rough surface of the casting and the workpiece after heat treatment. Sand blasting can clean all the dirt (such as oxide scale, oil stains and other residues) on the surface of the casting and forging, and the workpiece after heat treatment, and polish the workpiece surface to improve the finish of the workpiece. , Can make the workpiece exposed to the uniform metal nature, make the appearance of the workpiece more beautiful and good-looking.
(3) Deburring and surface beautification of machined parts. Sand blasting can clean the tiny burrs on the surface of the workpiece, make the surface of the workpiece more flat, eliminate the harm of burrs, 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) Improve the mechanical properties of parts After sand blasting, mechanical parts can produce uniform and fine uneven surfaces on the surface of the parts, so that the lubricating oil can be 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, sand blasting can realize different reflection or matt at will. 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.
Pre-treatment of non-stick coating for electric rice cookers-increase surface roughness;
Surface cleaning of stainless steel and chrome products-matte effect;
Water blast cleaning case for stainless steel welding process;
Second: sandblasting raw materials: sandblasting: technical terms for gold and silver coin casting. That is, on the production mold of gold and silver coins, various patterns of metal grit of different sizes are used to spray the pattern part into a very fine matte surface. When producing gold and silver coins, a beautiful layer of silver appears on the pattern part, which increases the three-dimensional sense and Layering. Refined quartz sand blasting (referring to metal surface rust removal or plating on metal surface) quartz sand, ordinary quartz sand, refined quartz sand: high hardness, good rust removal effect, physical and chemical indicators are as follows. SiO2≥88-99.8% Fe2O3≤0.1 —0.005%, fire resistance 1450 --- 1800 ℃, uniform appearance particles, commonly used particle sizes are 1-3MM and 0.1-0.3MM, pure white. The particle size range is mostly in the range of 5 to 220 mesh, which can be produced according to user requirements. Main uses: metallurgy, ink silicon carbide, glass and glass products, enamel, cast steel, water filtration, soda ash, chemical industry, sand blasting and other industries.
Sand material: Emery, glass beads, glass sand, resin sand, plastic granules, stainless steel beads, steel beads, aluminum beads, walnut sand, white corundum, alumina and other sand blasting equipment and equipment: water blasting machine, automatic blasting machine Through the sand blasting machine, polishing sand blasting machine, manual sand blasting machine, pressure sand blasting machine, etc., different sand blasting equipment handles different size workpieces, or the surface roughness, color and texture are different.
Three: Sand blasting process stage The blasting process uses compressed air as the power to form a high-speed spray beam, which sprays the blasting material onto the surface of the workpiece to be processed at high speed, which changes the appearance of the external surface of the workpiece. Due to the impact of the abrasive on the workpiece surface and cutting The effect can make the surface of the workpiece a certain degree of cleanliness and different roughness, and improve the mechanical properties of the surface of the workpiece.
Four: sandblasting process pre-treatment stage The sandblasting process pre-treatment stage refers to the treatment of the workpiece surface before the workpiece is sprayed and sprayed with a protective layer. The quality of the sandblasting process before and after treatment affects the adhesion, appearance, moisture resistance and corrosion resistance of the coating. The pretreatment is not done well, and the rust will continue to spread under the coating, causing the coating to peel off. After carefully cleaning the surface and the general simple cleaning of the workpiece, the coating can be compared with the exposure method, the life span can be 4-5 times. There are many methods for surface cleaning, but the most commonly accepted methods are: solvent cleaning, pickling, hand tools, power tools.
