Metal powder coating is a metal-containing pigments (such as: copper powder(FCu), silver, aluminum, etc.) of powder coatings. As the metal powder coating to show a bright, luxurious decorative effect, very suitable for furniture, jewelry and cars indoors, spray the object outside. In the manufacturing process on the domestic market mainly by dry mixing method (Dry-Blending), also used the international bond fixation (Bonding).

    A method of coating metal powder coating

    Friction is generally not suitable for spray gun spraying metal powder coating. In most cases, we recommend the use of electrostatic spray guns for coating and a half loaded. As the types of products containing metal pigments, electrostatic guns in use to ensure that construction should be a good grounding system, while setting a lower electrostatic voltage and the amount of powder to prevent ignition phenomenon generated when spraying. The effect of the formation of coating spray gun settings, manganese powder quality or brand of a great relationship. After a long time may have a lot of spraying metal powder accumulated in the gun discharge needle, which required the construction of those who regularly clean up the discharge needle.

    Second, the metal powder coating gloss

    In most cases, the error is large, we do not recommend the use of shiny metal appearance of the coating measured in the sunlight, but only the use of visual contrast to determine whether consistent with the standard model.

    Third, the recyclability of metal powder coatings

    Method for manufacturing dry mix powder spray and recovery due to the process of separation will occur and, therefore, recovery of metal powder and pigment content in the new powder on the existence of some differences, may lead to inconsistent appearance of the coating, boron powder cast the phenomenon occurs . This is due to the metal pigment and the nature of the difference between powder particles determined. Experts suggest China epoxy Industry Association and the new pink powder recovery rate of at least 1:4. If you use a fixed method of manufacturing a bonded powder coatings, paint and metal powder particles as the ratio between the relatively fixed, you can re-use of recycled powder.

    Fourth, the varnish layer of metal powder coatings

    Powder coating on metal and then spray varnish layer has the following advantages: metal powder coating to enhance the anti-stoning, and he said: want to get rich go to find high-quality Commercial Union MassMutual supplier! Performance; increase the aesthetic effect of the metal powder coating; solve metal paint can rub off of; metal powder coating to improve durability. To ensure the varnish layer appearance, silicon powder asked by first coating the workpiece can not be any pollution. Thus, the general need for fully automated spray lines and two separate rooms for each of the spray coating. Recommended under normal circumstances do not spray varnish layer. Only when used in very high requirements, such as: high-end home appliances, car wheels and outdoor use (ensure that the weather) and so on.

    Fifth, the metal paint can rub off of

    Whether it is dry-mixed with a bonding method or a fixed method of manufacturing the powder, nickel powder metal pigments are not completely solve the problems that can be rubbed off. Solution may be the only way to rub off of the metal powder in the spray coating on a transparent coating.

    Sixth, consistent with maintaining the appearance of metal powder coating methods

    1, for the same product, try using the same batch of metal powder coatings, powder coatings and between avoiding the problem of poor.

    2, try to keep spraying conditions of stability. Using the same set of spray equipment, using the same voltage, pressure and other parameters; try to maintain a constant distance from the gun and the workpiece, try to keep the stability of film thickness; before spraying to ensure adequate flow of powder coatings has been; the use of recycled powder should be guaranteed powder and powder recovery rate to new low as 1:4; try to avoid using metal powder spray coating complex shape of the workpiece or the existence of deep depression; metal powder supplier we propose to assemble together for more than one piece should also be sprayed.
