What is the distinguishing feature of
spring of non-metallic coating?
Spring factory introduced the nonmetallic material layer thickness of the spring is in the spring on the surface of dip coating or paint a layer of organic chemicals, such as paint, asphalt, plastic, etc. , to maintain the spring from erosion, nonmetallic material layer thickness, thick film, organic chemistry, good reliability, good mechanical equipment corrosion effect, but strength is low, easy to scratch, destroyed, another film layer has a brittle condition.
To spring the paint layer of paint generally has the following categories: a, epoxy zinc-rich primer, epoxy zinc rich primer with excellent resistant to moisture, waterproof, corrosion resistance, is very good alkali resistance and good resistance to acid.
But the poor adhesion, impact toughness, decorative art.
B, phenolic paint phenolic paint is divided into two kinds of paint and paint, phenolic paint adhesion, excellent antirust processing characteristics, but the film impact toughness and glossiness ability is poor.
Phenolic paint film hard real-time, good gloss, but the climate resistance is weak, the film is very easy to yellow.
C, alkyd paint alkyd paint film toughness, strong adhesion, good physical performance, good gloss, excellent performance and can have a certain resistance to acid and alkali, dielectric strength.
Its defect is the surface hard fast and the hands of time long, prone to wrinkle, resistant to moisture, alkali resistance.
D, epoxy resin paint epoxy resin paint adhesion strong, high strength, good ductility, and resistance to bending deflection, impact resistant, hard but not brittle, with many water, acid, alkali and solvent are good resistance ability, is more highlighted with alkali resistance.
Its defect is the surface layer of fast, organic solvent selectivity.
Water soluble epoxy resin paint to paint electrophoresis principle.
Under general conditions, the paint layer is applied independently, and can serve as a additive for after phosphating.
Sometimes, some of the spring so that according to the load is divided into class, also is not the same as the spray color paint to differences in many aspects.
Types and models of paint, which should be based on the office environment.
When required, shall be identified in spring sample figure.
