Scissors rust how to do? How to rust?
Shot peening (sand) rust removal. The utility model is mainly composed of particle spraying erosion to achieve surface cleaning and proper roughness, and the equipment comprises an open shot blasting (sand) derusting machine, a closed shot blasting (sand chamber) and a vacuum shot blasting (sand) machine. Open shot peening (sand) machine is widely used, can more thoroughly remove all impurities on the metal surface, such as oxidation, corrosion and old paint film, rust removal efficiency, 4~5m2/h, high mechanical level, rust removal quality. But because of abrasive generally can not be recycled, and other operations have an impact on the clean-up site trouble. Therefore, the environmental pollution is heavy, and has been gradually restricted.
Shot blasting. Blasting is the use of high-speed rotation of the impeller will be thrown to the abrasive surface of steel to achieve the purpose of rust removing, is a kind of advanced treatment method of mechanical rust for hull steel material, not only high production efficiency, low cost, and high degree of automation, can realize the pipeline operation, less environmental pollution, but only in the operating room.
High pressure water abrasive derusting. Using the impact of high pressure water jet (together with grinding action of abrasives) and water pry to destroy the adhesion of rust and coating to steel plate. The utility model is characterized in that the utility model has the advantages of no dust pollution, no damage to steel plates, and greatly improved rust removing efficiency, and can reach more than 15m2/h, and the quality of derusting is good. But after the rust of the steel plate easy to rust, paint must be painted with wet rust coating, coating on the general performance of a greater impact.
Small pneumatic or electric derusting. Mainly use electric or compressed air as power, assemble proper rust removing device, carry on reciprocating movement or rotation movement, in order to adapt to various occasions derusting requirements. As the angle grinder, wire brush, pneumatic needle beam device, pneumatic derusting and chipping hammers, tooth type rotary descaling device, which belongs to the semi mechanized equipment, light weight, high flexibility, can thoroughly remove rust, old coating, the coating for wool processing, greatly improve the efficiency than manual derusting. Up to 1~2m2/h, but cannot remove the oxide skin, the surface roughness is small, cannot achieve high-quality surface treatment quality, work efficiency is low injection processing. The utility model can be used in any position, and is widely used in the ship repairing process.
