Smooth Appearance Epoxy Powder Coating High Curing Temperature For Refrigerators

Product Specification

RAL 5010 Powder Coating Durability And Smooth Appearance Refrigerators Epoxy 

Advantage of Epoxy Powder Coating:

1. Healthy and environmentally friendly.
It eliminates the harmful effects of various liquid chemical additives such as film formation, dispersion, wetting, leveling, anti-corrosion and mildew resistance added to achieve coating performance.
2, convenient transportation and storage
Ordinary coatings contain about 20-50% water or solvent, while powder coatings have neither water nor solvent. They are completely solid, convenient and safe to transport. In addition, water or solvent coatings have low transport and storage temperatures. At 0 ° C, it tends to freeze, and powder coatings do not have this problem.
3, no preservatives required
In traditional liquid paints, there are both water and bacterial foods, which are easily contaminated by bacteria. Therefore, in order to prevent deterioration, preservatives are added, and latex powder coatings have no bacterial contamination problems and no preservatives are needed.
4, paint smell
Compared with the traditional paint odor residue, this paint can be dissipated quickly, which can be said to be instant.

Powder coating construction process and requirements:

The so-called powder electrostatic spraying is the principle of using a high-voltage electrostatic corona electric field. A high-voltage negative electrode is connected to the metal guide of the spray gun head, and the workpiece is grounded to form a positive pole, so that a strong electrostatic electric field is formed between the spray gun and the workpiece. When the powdered paint is sent from the powder supply tank to the guide rod of the spray gun through the powdery tube as the compressed air of the carrier gas, a dense negative charge is generated in the vicinity of the guide rod due to the corona discharge generated by the high voltage negative electrode. The powder is negatively charged and enters an electrostatic field with a high electric field strength. Under the dual action of electrostatic force and carrier gas, the powder uniformly flies to the surface of the grounded workpiece to form a thick and uniform powder layer, which is then heated and solidified into Durable coating. Painting construction process Pre-treatment, drying, removal of water, spraying, inspection, baking, inspection, inspection, finished product, construction requirements, general powder coating construction requirements

(1) To maximize the performance of the powder coating and extend the life of the coating film.
(2) When spraying, the object to be coated must be completely grounded to increase the spraying efficiency of the powder coating.
(3) Check immediately after dusting. If defects are found, they should be treated in time. If defects are found after curing, the range is small and only partial and does not affect. The surface of the coated object is decorated. It can be repaired with the same color powder and diluted with acetone. If the surface quality is affected, sanding with sandpaper, spraying again or removing the coating with a paint remover, and then re-pulping.
(4) The recovered powder shall be mixed with the new powder at a certain ratio after screening to remove the impurities.
2, art-type powder coating construction requirements: art-type powder, with beautiful features, strong three-dimensional sense, good decorative effect, etc., but the construction process requirements are strict.
