Any enterprise should formulate professional and operable enterprise production standards according to the characteristics of its own products and production methods. The so-called professionalism is to have a wide range of versatility and interchangeability. To participate in international trade, it is necessary to adopt international standards for production. Only high-standard products can obtain market access certificates. The required operability means that the established standards can be accepted by users and ensure that the products produced according to this standard have appropriate profit margins. Therefore, in the process of formulation, different levels of standards can be formulated according to the differences in product application levels. . This requires the collection of the following technical information:
(1) The user's coating quality requirements for the company's products;
(2) National standards or industry standards and regulations;
(3) International standards and foreign professional standards;
(4) The coating equipment of the enterprise;
(5) Basic rules for writing standards.
The content of the coating quality standard formulated should include the following aspects:
(1) Quality requirements for pre-paint treatment, such as cleanliness, surface roughness, chemical conversion coating quality, etc.;
(2) Coating quality requirements, including appearance quality, gloss, color, thickness, adhesion, hardness, etc.;
(3) Requirements for the selection of coatings, such as coating types and matching properties, construction properties and construction conditions (such as coating methods, coating temperature, humidity, coating intervals and drying conditions);
(4) Inspection methods and inspection rules. The inspection rules refer to whether a certain performance is to be inspected or fully inspected; the inspection scope and inspection frequency; the regulations for judging whether a certain performance is qualified or unqualified, etc.
