How to do polyurea anticorrosion? Dry sand blasting problems should be designed to require Sa2.5 level as much as possible. Abrasives should try to use non-metallic materials, such as garnet, quartz sand, etc., to meet the development requirements of the GB8923 standard as much as possible. If this condition cannot be met, we can choose one by ourselves. Artificial intelligence mechanical polishing, it is recommended that companies use sandpaper or louver for research and polishing, and the grade should reach St3 and above at the same time, and the cross method is likely to create a certain surface roughness, avoiding the pollution and lubrication layer caused by the use of steel wire wheels. surface. Use dry and oil-free clean compressed air to blow away the dust on the surface. If economic conditions permit, users can use alcohol to scrub the artificially polished surface in our country. During the scrubbing process, you need to cultivate good ventilation and maintain information security.
The surface density of non-ferrous metals is much higher than that of carbon steel. I do not recommend manual sanding. Use dry sandblasting to lightly increase the surface roughness. According to experience, the roughness is about 40 microns. Whether it is carbon steel surface treatment, non-ferrous metal surface treatment, the choice of primer is very important. The author recommends to choose a shade-resistant peeling primer, which can fully meet the adhesion requirements of polyurea spraying. Among them, a polyurea special primer The pull-out test has reached 11.2MPa.
In short, the use of this kind of corrosion-resistant and waterproof material is good, otherwise it will become rubbish. The key to the success or failure of this quality lies in the high-quality treatment of the base layer and the choice of the primer. The author has seen from a large number of cases that 70% of the polysaccharide quality lies in primary care, and 30% lies in materials and technology. If you have mastered these two points, such as the use of anti-corrosion and waterproof materials for fish water, I believe that in today's environmental protection, the VOC content is required to be less than 10% of the quality of your own paint, or the VOC-free high-solid materials are increasingly subject to corrosion protection. Favored by the industry, including solvent-free coatings, thermal spray polysaccharides, electrophoretic coatings, powder coatings, water-based coatings with high heat.
