30 years of experience experts: sand blasting process and the main points of attention; sandblasting Technology: sandblasting and shot blasting which is better? Today, the professional team of Han Tong Industrial Co., Ltd. 30 years professional team research and development experts to say “the key points of sand blasting processing, sand blasting processing and shot processing which is better”, let you have more understanding of the industry in addition to the prior understanding of the shot processing.
The main points of the sand blasting process are that the first sand blasting equipment is as close to the work as possible to reduce the length and pressure loss of the pipeline, avoid excessive pipe wear and facilitate the construction personnel to connect with each other; the sand hose is striving straight to reduce the pressure loss and the concentrated wear of the abrasive to the hose. In order to prevent leakage and air discharge, reduce the number of displacement, increase the use efficiency and efficiency of the abrasive, the spray position should be considered, the injection route is set up, the air pressure, the amount of sand out of the air and the surface pollution of the structure. The moving speed of the nozzle is mastered flexibly.
During the injection process, the metal injection process is adjusted in time according to the air pressure, the diameter of the nozzle, the corrosion state of the structure surface, the quality and efficiency of the treatment. After the surface pretreatment, the dust and debris are cleared with dry and oil free compressed air. The surface of the cleaned surface shall not be touched by hand; before painting, it is found to be found. The surface of the matrix metal is contaminated or rusted, and it must be retreated. After the pretreatment is completed, it needs to be sprayed as soon as possible, and the shorter the time the better. In wet or industrial atmospheric pressure and other environmental conditions, it is necessary to finish the coating in 4h, sandblasting in sunny days or when the temperature is small, and the longest interval of the processing of sand blasting in Han Tong industry is not more than 12h. This is the process of sand blasting process and the main points for attention.
