Grade Sa2.5 shot blasting and rust removal improves the internal quality of steel and prolongs the service life of components
Time: 2022-01-21    View: 651    Burst: 

During block machine components processing, the quality of the processing technology directly affects the power, economy, reliability, construction quality, production efficiency and service life of the equipment after installation, commissioning and operation.

QGM adopts Sa2.5 grade shot blasting and rust removal processing technology to carry out deep processing of steel. The shot blasting machine throws high-speed centrifugal force to clean the surface of the workpiece at high speed. After shot blasting, the steel has anti-fatigue, anti-corrosion ability and surface adhesion. And the aesthetics are greatly improved, which not only improves the inherent quality of the steel, but also prolongs the service life of the components. QGM guarantees product quality with excellent machining technology and escorts your production.



What is Sa2.5 shot blasting and rust removal? This needs to start from the use of SIS055900 for the international sandblasting and rust removal standard for metal surfaces. The standard is divided into Sa1, Sa2, Sa2.5 and Sa3. Compared with ordinary shot blasting and rust removal, Sa2.5 rust removal surface cleaning, Strengthening, finishing, deburring effect is better.

Standard level Instruction
Sa1 Mild spraying or projecting to remove rust, the steel surface should be free of visible grease and dirt, and there should be no adhesions such as oxide scale, rust and oily coating that are not firmly attached;
Sa2 More thorough spraying or projecting rust removal, the steel surface will be free of visible grease and dirt, and oxidized. The attachments such as rust and paint coating have been basically removed, and the residues should be firmly attached;
Sa2.5 Very thorough spraying or projecting rust removal, the steel surface will be free of visible grease, dirt, scale, rust and paint coating attachments, and any remaining traces will be dots or streaks of slight stains;
Sa3 Thoroughly cleaned grade surfaces are uniformly off-white with some roughness to improve coating adhesion.

The main frame of QGM ZN1500C automatic block making machine adopts high-strength frame structure, designed by QGM patented appearance technology. The frame is made of special steel through welding, shot blasting and rust removal and other processes. The steel has strong fatigue resistance and corrosion resistance, and the aging vibration treatment is carried out on the entire frame, to ensure the high quality and high stability of the frame. The advanced structural design process makes the mainframe expandable, and functions such as side mold opening and closing functions and polystyrene board implantation can be added later according to production needs.
