In the manufacturing process, the present day Chinese marketplace is particularly taking the Dry-Blending method, the worldwide community also use alliant steel powder for sale Bonding method. In maximum cases, we advise the usage of an electrostatic gun for coating. Metal powder coating’s coating technique, the friction gun is typically now not appropriate for the coating of steel powder coating. Due to this form of merchandise containing metallic pigment, while the usage of an electrostatic gun in construction need to make sure that the machine is nicely grounded, setting a lower electrostatic voltage and powder amount at the same time, prevent producing ignition whilst spraying. The impact of forming a coating movie and the gun putting, the first-class or logo has a tremendous courting. After longtime spraying, there are can be a variety of metallic powder amassed in the gun discharge needle, which required the constructor regularly easy up the release needle.
The shine of metallic powder coatings in maximum cases because of the error is massive, we do now not advocate the use of gloss tool to measure steel appearance coating gloss, but best by visual contrast method to determine whether it’s far the same with sample. The recyclability of the steel powder coating for the powder manufactured via dry blending method, because of inside the technique of spraying and healing will arise separation, for this reason there are some variations on recycling powder and new powder’s metal pigment content material, may also reason the coating movie look inconsistencies, appear color cast. This is because the metallic pigment and the nature of powder debris difference. Experts propose that the reclaimed powder and new powder’s ratio should at the least 1:4.
If use adhesive solving technique production powder coating, due to the ratio of metallic pigment and powder particles is surprisingly fixed, then it can re-use recycled powder. Spray varnish layer on metallic powder layer has the subsequent blessings: Enhanced metal powder coating’s anti-stoning properties; growth the cultured effect of the coating metallic powder; completely solve the scraped property of metallic pigment; enhance weatherability of the coating steel powder. To make sure the arrival of varnish layer, requiring workpiece via first spraying need to not be concern to any contamination. Thus, it commonly desires for fully computerized spray lines and two separate rooms for each spray portray.
Recommended underneath regular circumstances do no longer spray varnish layer. Only the usage of in very annoying, which include: excessive-quit home equipment, automobile wheels and outside use (to make certain durability) and so on. Metallic pigments’ scraped belongings, both with the aid of dry-mixing approach or bonding method manufacturing powder, were now not completely resolve the hassle of metal pigments’ scraped belongings. The simplest manner to resolve the scraped belongings is spraying a layer of transparent coating film inside the metallic powder layer. The technique to maintain the steel powder coating look consistent: for the identical product, try and use the equal batch of metallic powder coatings, avoid the difference between powder coatings batches; keep spraying situations stabilize.
Using the same set of spray device, the usage of the same voltage, strain and other parameters, attempt to maintain the gun and the workpiece distance now not change, try to keep the stableness of the film thickness; guarantee powder coatings have been absolutely fluidized earlier than spraying; even as the use of recycled powder ought to make certain the ratio of healing powder and new powder less than 1:four; advocate a couple of elements to be assembled together spraying at the identical time.
