Jin Huajin artisan paint co., LTD. Has experienced high-quality professional and technical personnel dozens of, in-depth technical research collaboration, and successfully developed with the main intellectual property high stability performance of control system, are very influential in the industry.

Sand blasting, shot blasting derusting, manual and dynamics, the aim, in addition to achieve the certain surface cleanliness, also has certain micro steel surface flatness, namely the surface roughness. For before paint for steel surface of roughness usually with some of the major highly values between the peaks and troughs. The steel surface roughness of the coating adhesion, corrosion resistant performance and protect the life has very big effect. Suitable for steel surfaces roughness is beneficial to the improvement of the performance of the paint film protection, roughness is too small, is not conducive to the improvement of adhesion of paint film, roughness is too large, such as the dosage of paint film must, can cause the film thickness distribution is not uniform, especially in the wave of the film thickness is insufficient and below the design requirements, cause the corrosion of the early, in addition, the roughness is too large, also used to live in the trough of the deep pit retaining bubbles, will become the root of the paint film of bubble.
