Description
Technical field
The present invention relates to a kind of baking vanish, the white enamel polyester paint of especially a kind of bloom for aluminium.
Background technique
Coating is that one kind can be coated in object surface with different construction technologies, and formation is sticked securely, with centainly strong
Degree, continuous solid film.The film common name film formed in this way, also known as paint film or coating.It is divided into liquid coating by coating form
(solution-type, emulsion-type, dispersing type, no-solvent type), solids coating (powdery paints) etc.；By coating applications be divided into building coating,
Industrial coating, universal lacquer, sapecial coating；It is divided into water paint, solvent based coating, no-solvent type coating etc. by decentralized medium；
It is divided into antirusting paint, anticorrosive paint, heat-resistant coating, fireproof coating, coatings, antifouling paint etc. by functional coating film；By film
Function is divided into antirusting paint, anticorrosive paint, heat-resistant coating, fireproof coating, coatings, antifouling paint etc.；By construction method point
For spray painting, dipping lacquer, electrophoretic paint, certainly swimming paint, roller coating etc..
Coating has reflected light, shines, absorbs and reflect infrared ray, absorbs the light such as solar energy, shielding ray, flag colors
Learn the effect of aspect of performance；There are also various different roles such as antinoise, vibration damping, disinfecting, anti-condensation, anti-freeze etc..Coating
It is strong to ground or to the adhesive force of old paint film the features such as appearance gloss, color is fine and smooth with protecting light colour retention, there is hardness, punching
