Glitter Spray prone finished surface quality defects and in the production process of our approach.
First, the adhesion is not enough: When the billet surface degreasing without a net, chromium film substandard quality, but the quality of the powder itself off, the curing temperature is too low or insufficient curing time, have a great influence on the coating adhesion,
Response measures: strict control on the pre-treatment; powder timely replacement of non-conforming strictly in accordance with the technical requirements and the temperature and time for curing.

Second, the shrinkage: Normally, to produce shrinkage There are several reasons:
???? A powder to absorb moisture when stored.
???? 2, the blank surface pretreated oil, water and other pollutants.
???? 3, spraying with water or compressed air oil.
???? Corresponding solution is: powder kept in a dry, temperature extremes; pretreated profiles, the handling process prevents water, oil pollution; compressed air pipes reasonably designed to prevent moisture or oil gathering area, if necessary secondary treatment for compressed air.

Third, the coating thickness is uneven, causes:
???? 1, powder coating speed uneven.
???? 2, for the powder means poor or fluidized powder moisture agglomerate.
???? 3, the conveyor speed is uneven.
???? Response: stable supply pressure, always monitor the quality and flow of the powder effect, regulate the chain speed, profiles reasonable mount.

Fourth, the coating pale, discolored, low gloss causes:
???? 1, the powder coating heat resistance.
???? 2, the baking time is too long or the temperature is too high.
???? 3, dusting and curing process interval is too long.
???? 4, for the powder and powder systems, recycling, or mixed with different colors, nature of the powder.
???? Response: Change hot and good powder; shorten the baking time and temperature; spray as soon as possible after curing; powder room equipment clean.
