What information and parameters should be provided when ordering a coating line?
1, the whole product of the largest workpiece specifications: length, width, height, weight;
2, the product name of raw materials, material thickness, hanging way;
3, the annual output, the number of working days, working hours for the number?
4, the surface with or without oil;
5, the surface with or without corrosion;
6, to be used in the coating process for the powder, paint or varnish, cathodic electrophoresis, anodic electrophoresis;
7, the workpiece to spray what color, color cycle, film thickness and paint types;
8, the production form: automatic / intermittent;
(T / h), tap water (T / h), compressed air (M3 / min), thermal energy for fuel or gas form;
10, the plant can use the actual area and effective height.
Painting production line process is divided into: pre-treatment, dust coating, heating curing.
Production line of the pre - treatment section of the coating production line
Pre-processing manual and automatic pre-processing process, which is divided into automatic spraying and automatic immersion two processes. The workpiece must be surface-treated to remove the oil before stripping. In this section of the liquid used more, mainly derusting agent, degreasing agent, table swap, phosphating agent and so on.
In the painting line before the processing section or workshop, the first thing to note is to develop the necessary strong acid and alkali purchase, transportation, custody and use system, to provide workers with the necessary protective clothing, safe and reliable dressing, handling equipment, and The development of emergency measures in case of emergency, rescue measures. Second, in the coating production line before the treatment section, due to the existence of a certain amount of waste gas, waste and other waste substances, so in environmental protection measures, must be equipped with exhaust, drainage and waste treatment device.
Pre-treated workpiece quality, due to pretreatment and coating production line process is not the same, its quality when there are differences. Handling the workpiece, the surface oil, rust to do, in order to prevent a short time again rust, generally should be in the pre-treatment after a few processes, the phosphating or passivation treatment: before the powder, The workpiece is dried to the surface of the water. Small batch production, the general use of natural dry, dried, dry. For high-volume flow of operations, generally take low-temperature drying, the use of Oven
or bake Road.
