Poor ground sanding can cause shrinkage. Contamination of the coated surface with wax or grease will also cause shrinkage of the floor paint film. The compressed air used in the construction of spray-painted floor paints contains excessive amounts of water or oil-like substances and can also cause shrinkage in epoxy floor paint films. Floor paint is contaminated on the construction site (if there is dust, water droplets, and grease droplets, etc.), it can also cause shrinkage. Epoxy floor paint coating does not support the shrinkage phenomenon.
According to experts, epoxy floor coatings companies generally deal with such issues as follows.
The bottom sanding should be uniform, and at the same time, it must be fully polished, and there must be no place for leakage. Finally, it is thoroughly and uniformly sanded with fine sand (high-mesh) paper, and the dust generated by the sanding is cleaned and the floor paint is applied. Work can be resolved. Thoroughly clean up the contaminated painted surface, and then conduct floor paint construction to avoid such phenomena. Thoroughly clean up the air compressor, the conduit, the water and grease in the spray gun, and then proceed with construction. Or look for sources of pollution, block pollution from the source, and handle the environment of the floor paint construction site. Use a compatible epoxy floor paint.

Oushida is second quality machine,but the quality also similar with longneng quality.only different is the Motor material. Longneng is 45# baosteel cold-rolled.Oushida is 60# cold-rolled baosteel.608 bearing use C&U.another one is scnc, another is CHL.
We have self machinery room to control the aluminium allowable error.We also removal the dust that every process machining to control no more tolerance on the spare.
There is testing room to control the quality stable.
