Sand blasting machine in use, need to understand its process, so as to reduce equipment operation failure, promote the use of equipment efficiency, and for the convenience of more users to understand the use, the next detailed process is introduced to understand.
Comparison with other pretreatment processes (such as pickling and tool cleaning)
1) Sandblasting is a more thorough, bottom, more general, faster and more efficient cleaning method.
2) Sandblasting treatment can be arbitrarily selected between different roughness, and other processes can not achieve this, manual grinding can hit the wool surface but the speed is too slow, chemical solvent cleaning is too smooth to clean the surface is not good for coating bonding.
Sand blasting application
(1) Workpiece coating and plating, and workpiece bonding before processing
Sandblasting 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, the so-called wool surface), and can achieve different degrees of roughness by changing the abrasive of different particle sizes, greatly improving the binding force of the workpiece and coating and plating. Or make the bonding piece more firmly, better quality.
(2) Cleaning and polishing of the raw surface of cast and forged parts and the workpiece after heat treatment
Sandblasting can clean all the dirt (such as oxide scale, oil and other residues) on the surface of the workpiece after casting and forging and heat treatment, and polish the surface of the workpiece to improve the finish of the workpiece, and beautify the workpiece.
Sandblasting cleaning can make the workpiece reveal a uniform metal color, make the workpiece appearance more beautiful, to beautify the role of decoration.
(3) Burr cleaning and surface beautification of machined parts
Sandblasting can clean the tiny burr on the surface of the workpiece, and make the surface of the workpiece more smooth, eliminate the harm of the burr, improve the grade of the workpiece. And sandblasting can play a small rounded corner at the junction of the workpiece surface, so that the workpiece appears more beautiful.
(4) Improve the mechanical properties of parts
Mechanical parts after sandblasting, can produce uniform fine concave and convex surface on the surface of parts (basic diagram), so that the lubricating oil is stored, so that the lubrication conditions improve, and reduce noise to improve the service life of machinery.
(5) light decoration
1, all kinds of workpiece surface polishing, make the workpiece surface more beautiful.
2, the workpiece to achieve smooth and reflective requirements.
For some special purpose workpiece, sandblasting can achieve different reflective or matte light. Be like surface of furniture of stainless steel workpiece, ligneous inferior smooth change, the decorative pattern design of surface of ground glass, and the wool that cloth surface changes process to wait.
