How to spray stainless steel mesh belt.
2020-08-03
Pretreatment of the stainless steel mesh belt, in order to make the coating film strong adhesion, not easy to fall off, and long life, the appearance of the stainless steel mesh belt must be pretreated before spraying. Coating dryness is divided into physical dryness and chemical dryness according to the nature of the coating itself. The pretreatment of the Great Wall mesh belt is very linked, and spraying also requires a process. It is divided into three processes. First, the pretreatment of the predecessors is performed, then the spraying, and finally the drying. The order of the three processes cannot be interchanged. There are dozens of paints such as grease paint, natural resin, epoxy resin, phenolic resin, etc., which can be selected according to actual conditions.
The stainless steel mesh belt is boring in order to make the coating function excellent, strong and wear-resistant, it must be used after it is fully boring. Different stainless steel mesh belts have different pretreatment methods. There are many methods for spraying, such as manual, active, electrostatic, electrophoresis, etc., which can be selected according to the batch size and shape of the Great Wall mesh belt.
The spraying process and methods are also different according to the type, function and curing conditions of the coating. Users can according to the shape, size and batch of stainless steel mesh belt. In practice, for rapid drying, solvent volatile coatings or thermal curing coatings are often used, and the ideal effect can be achieved through natural drying or simple drying processes. Steel parts are mainly treated by degreasing, derusting, phosphating and other treatments. Commonly used water cleaning liquid decontamination and degreasing, mechanical or chemical derusting, phosphating is to immerse the parts in an acid diluent (density 1~1.1, PH =1~3), there will be a reaction at the interface of the two.
