Long time after spraying may have a large number of metal powder accumulation in the spray discharge needle, need to clean discharge needle regularly.

Because of the metal powder coating can exhibit a bright, luxurious decorative effect, is very suitable for the furniture, jewelry and cars, and other indoor objects outside the spray. In most cases, recommended the use of electrostatic spray coated.

In most cases, due to the error is very large, we do not recommend using gloss meter measuring metal exterior coating gloss, but only by visual comparison method to judge whether a model consistent with standard. Therefore, it generally need to have fully automated spray lines and two sets of independent spray room to coat respectively.065%; the latter is with high pure nickel carbonyl powder, in the appropriate lubricant and the presence of a fluid medium, with the ball in the ball mill grinding forming suitable thickness of sheet. To solve the erasable fallen, only method for metal powder coating is sprayed with a layer of transparent coating. For dry mixed manufacturing powder, because the spraying and recovery process will occur separation phenomenon, so the recovery powder and powder in metallic pigment content can have certain difference, may lead Sintered Powder Metal Gears to the appearance of coating is inconsistent, Injection Molding Powder Metallurgy Copper-Based Parts partial color phenomenon. This is because the metallic pigment and powder particles property is difference.

. In the use of electrostatic gun construction should guarantee the system a good grounding, and set low electrostatic voltage and prevent the spraying powder amount, cause the phenomenon of striking. In order to ensure the light shade layer appearance, for the first time coating cannot be subject to any pollution. For the same product, try to use the same number of metal powder coatings, avoid powder coatings have error problem between batch. Suggest not to spray light shade layer. The effect of forming coating and spray set, quality or brand has very big relations.

The metallic pigments with nickel as the main component, including nickel and nickel powder, the former is through distillation and purification of nickel carbonyl steam decomposition, by controlling the temperature, dilution and using carbon monoxide gas additives ( oxygen and nitrogen ) formed under suitable shape of Ni particles, then rinse carbon monoxide and carbon dioxide gas control of particle surface oxygen content was 0.mhcmp. Whether by dry mixing method or by bonding method of manufacturing powder, can not completely solve the metallic pigment can be erased problem. Mainly used in coatings and plastics as conductive pigment shielding electromagnetic interference and radio frequency interference, for a variety of decorative high gloss paint and plastic, instead of aluminum powder in aqueous system for anti corrosion paint, fine particles and spherical nickel powder can be used for the conductive ink. Friction spray gun is generally not suitable for metal powder coating spraying.

Spray cover layer in metal powder coating has the following advantages: reinforced metal powder coating stone-impact resistance; adding metal powder coating appearance; completely solve the metallic pigment can be erased; improve the metal powder coating weatherability.Metal powder coating means containing metallic pigment ( such as: copper gold powder, silver powder, nickel powder ) of various powder coating
