Next to introduce several blasting method, a small pneumatic or electric rust: mainly electricity or compressed air powered Sand, rust proper device assembly, reciprocating or rotational movement to suit all occasions rust requirements; 2, smear paint oxidation: the iron products coated with mineral oil, or baked enamel paint, spray and so on. In the steel surface by plating, methods such as hot dip coated with a layer of rust metal, such as zinc, tin, chromium, and nickel. These metals can form a dense surface oxide film, thus preventing iron products and water, air and other substances in contact rust. Chemical methods can also be used to make iron products formed on the surface layer of dense and stable oxide film to prevent rusting iron products. To remind the user to use the equipment and idle time, maintenance and repair should be carried out, can not relax, good performance of the device is a symbol of benefits for enterprises. In fact, higher development goals throughout the planning. As Guangdong, Sichuan, Inner Mongolia, Yunnan planned highway are about 10,000 km. If parts of the highway planning summary, according to the expert estimates, close to 200,000 km. Highway construction is inseparable efficient Sand, a large supply of high-quality sand and gravel, sand and natural stone has long been in short supply. Roadworks aggregates used mainly two kinds of gravel and sand. Orthopedic various clay aggregates concrete, in general, particle size more than 2mm called gravel, sand was 2-0.074mm of. Sand cement mortar, the main source of raw brown cement concrete, asphalt concrete and tar sands, sand with natural sand (sand mountain, river sand, sea sand) and artificial sand (sand) two. The high quality of artificial sand, and less restricted by natural conditions, has been widely used increasingly over. Energy efficient sand production line is the source of high quality sand stone, and as a mechanism for efficient crushing machine production line in the sand core crushing equipment plays an irreplaceable role. Under the influence of the country to invest heavily in road construction, manufacturing high-quality sand and gravel in order to become a gold industry.
