Sandblasting machine working principle is to use compressed air to drive abrasive (or bullet) into the surface of workpiece, the workpiece surface of micro cutting or impact, in order to realize the workpiece derusting, paint, surface impurities removal and surface strengthening and deal with all sorts of adornment sex. Widely used in ships, aircraft, metallurgy, mining, railways, Bridges, chemical, vehicle and heavy machinery industry in manufacturing all kinds of metal components and welding surface. And non-metallic (glass, plastic, etc.) on the surface, adornment, sculpture, an ideal equipment. I sandblasting machine series product, the steel surface descaling grade up to Sa3 (before coating steel surface corrosion level and the highest level in descaling grade standard GB8923-88). No visible at this point, the steel surface of grease, dirt, scale, rust and paint coating and other attached objects, according to uniform metal color. Steel substrate surface roughness can reach more than Ra40um, with epoxy zinc-rich paint bonding strength can be greater than 12 mpa, greatly improving the steel surface with paint anticorrosion coating binding force, corrosion life of up to more than 20 years. For shot blast, a large number of the projectile into the surface of parts, violent impact to make metal parts surface is very strong plastic deformation, make the parts surface produces a certain thickness of cold work hardening layer, called surface strengthening layer, the strengthening layer will significantly improve parts fatigue strength under high temperature and high humidity. In addition, shot peening can also prompt the steel surface of organization change, namely the residual austenite into martensite induced, and refinement of martensite substructure, further improve the surface hardness and wear resistance, and extend its service life. By actual test, shot peening for 10 seconds, high arc specimen deformation can reach 0.6 mm, flipping rate was 100%. For sand blasting process of a large amount of dust, we design a series of recycling sandblasting machine and sand blasting room. Can solve the problem of environmental pollution, job site can achieve "GB103328-10333-89 health standard for dust in the air of workplace", is the upgrading domestic environmental protection equipment. The sandblasting machine produced by our company have many national patents and ISO9001:2000 quality management system certification, and access to the 1996 Beijing international invention exhibition bronze medal. The following is my company sandblasting machine product application instance. Contact: Mr. Han 15010113682
