Problems that should be paid attention to before and after use of polyurea spraying equipment:
First of all, after spraying every day, or when changing the variety of spraying materials, the residual materials of spraying equipment and conveying pipelines should be removed, preferably once a day. The operator must be familiar with the equipment and master the operating procedures before taking up the job. For the barrel cover at the bottom of the barrel and the spray switch inside and outside the barrel, the switch must be placed in the correct position and cannot be misplaced. The coating pipeline should not be bent too much, so as not to cause unnecessary pressure loss and affect the service life of the pipeline. If multiple jet pumps are used in series, a condenser is added between the pumps to condense the steam and obtain a higher degree of vacuum. The whole steam jet vacuum pump consists of two parts: pump body and condenser. All pump bodies are composed of nozzles, chambers and diffusers. The nozzles can be single or multiple. The nozzle is made of stainless steel, and the suction chamber and diffuser are made of stainless steel, cast iron, carbon steel and other materials.
The use of polyurea sprayer and spraying work should be effective enough for the spraying booth where fireworks and firecrackers are prohibited, and the fire-fighting equipment in the spraying work area. The surface of the pool between materials should be kept below the foam board, and it should be replenished in time when it is insufficient. The material can not be mixed with dust and foreign matter to ensure the smooth flow of the nozzle and avoid clogging. After cleaning the spray gun, it is used for material barrels and spraying construction work, and the floating objects floating on the surface of the material should be sprayed into the water regularly. The cleaned nozzle should be coated with Vaseline ointment. Avoid mixing water into compressed air to prevent rusting of drive components and damage to cylinders. Adjust the medium viscosity paint, stir well, and fully before use.
