The properties of plastics are constantly improving, and plastic parts are gradually entering various industries. Today, the annual demand for injection mold processing in building materials, Toyota Car, household appliances, electronics and other fields is still relatively strong. The rapid development of these industries has also brought the development of the plastics industry, especially, into a stage of rapid development.
In the production of Petrol Car parts, the coating adhesion problem of plastic products is a key process measure. In order to solve the problem of coating adhesion of plastic parts of Toyota Car, it is necessary to understand the process flow of coating plastic parts of Toyota Car. According to the editor's collection, the process flow of plastic parts of Toyota Car can be roughly divided into the following categories: part:
The blanks are polished, chemically treated, dusted, sprayed with primer, painted with one color (or metallic flash paint), varnished, baked, delivered for inspection, qualified products put into storage, and unqualified products returned for repair or paint removal.
It is understood that among these many process links, the most important link to improve the coating adhesion of plastic parts is pre-paint pretreatment. The purpose of pre-painting pre-painting for Petrol Car plastic parts is to improve the adhesion of the paint to the plastic through a series of physical and chemical methods, reduce various defects in the coating, and thereby improve the quality of the plastic coating. Pretreatment of plastic parts before painting includes conventional treatment, acid treatment, flame treatment, surfactant treatment, hot solvent treatment, ultraviolet treatment and plasma treatment.
In addition, in order to improve the coating adhesion, the surface treatment and construction environment before coating of plastic parts should be strictly controlled during the construction process to ensure the coating quality. While using new plastic materials, attention should be paid to improving their surface tension. and polarity, change the pre-treatment process and primer variety if necessary.
