Blaster is a developed countries in Europe and the United States has begun the application of shot blasting surface treatment methods. First shot blasting equipment in the world was born 100 years ago began to remove the impurities in a variety of metal or non-metallic surface oxide increase in roughness, etc. are applied. After centuries of development. shot blasting treatment process and equipment is already quite mature. its application not only in all of heavy industry factories With the level of the world's first mobile shot blasting equipment in the United States Bai Lai Taike (BLASTRAC), the birth of its application field is rapidly expanding into the concrete surface coating processing and ship the deck metal surface treatment and boot directly to the norms of the industry's standard-setting and industry construction methods.
With the continuous improvement of the the Bai Lai Taike shot blasting equipment and technology is mature. Shot blasting treatment processes and equipment have entered the European and American developed countries, road maintenance, bridge construction and airport maintenance and other areas of China in this regard is still very small blasting treatment process used only in a few projects in the highway. municipal roads and concrete the bridge are waterproof coating or a blank. your poem Di (GSD) would like to take this article can this new shot blasting The treatment process introduced to the highway maintenance and construction of bridge engineering counterparts and look forward to the new process technology promotion.
(1) shot blasting process and blasting treatment equipment works
Shot blasting is a mechanical method of abrasive (steel shot or sand) at high speed and a certain angle of the projectile to work on the surface of pills expected to impact the work surface inside the machine by supporting cleaner air cleaning the pill material and clean up down impurities, respectively, recycling, and the pill material can again use the technology. shot blasting machine with a dust collector. can do is clean pollution-free construction. both to improve efficiency and protect the environment. shot blasting The machine according to walking in the form can be divided into three types: hand push the vehicle-mounted and self-propelled.
The shot blasting machine operation through control and choice of abrasive particle size, shape and adjust and set the travel speed of the machine. Control pills material ejection flow. Different projectile strength. Different surface treatment.
1.2 surface shot blasting quality control
Shot blasting process and blasting treatment equipment based on the need to deal with the different surface of the three parameters to control the status of the treated surface. Select the size and shape of the pill material, equipment, travel speed, abrasive flow rate. The three parameters with each other. can get different treatment to ensure the ideal roughness of the surface after blasting treatment.
Such as: S330 steel shot. Flow 10A. Processing of C50 concrete surface roughness of 90 can be achieved to deal with the asphalt surface. Can remove the pan-reservoir. Roughness of 80 at the same time, deal with the steel plate. SA3 cleanliness standards can be achieved.
The drum abrator: the use of high-speed impeller placed projectile thrown flip the casting drum cents. Forging clear the oxide so that the workpiece surface for uniform cleaning and showing the metal colors.
The crawler abrator: workpiece is loaded by high-strength wear-resistant rubber track or manganese steel crawler and high-speed projectiles thrown by the blast wheel will flip the workpiece on the crawler. Achieve the purpose of cleaning up.
Rotary shot blast cleaning machine: frequency shot blasting allows the surface to be uniform steel shot striking force and the surface of the steel shot more than 98% coverage in order to achieve the strengthening effect.
Step-by-step hanging chain shot blasting machine: a multi-bit fixed point where the projectile to clean up the sticky sand casting surface oxide scale removal. Casting reproduce the metal color.
