Yantai electroplating : analysis and solution of dry marks on electrophoretic paint film

Electrophoretic paint, as a safe, environmentally friendly, high-quality and efficient coating, has been widely used in large-scale industrial production of metal anticorrosive coatings in various industries. Due to the relatively high technical requirements for large-scale electrophoretic coating production, some deviations in management, or seasonal changes, etc., may often cause such or other disadvantages, such as shrinkage, particles, etc., on the electrophoretic coating film. Dry marks are also one of the possible abnormalities in electrophoretic coating production. The following is an analysis of the causes and countermeasures by professionals.

电泳漆

The dry marks on the electrophoretic coating film are generally because the time between the coated object and the electrophoresis tank is too long, or the cleaning is not sufficient after electrophoresis, which causes the bath solution adhered to the wet electrophoretic paint film to dry out. Marks on the film surface are called dry marks or dry paint marks.

cause:

、电泳至水洗之间的时间太长。 1. The time between electrophoresis and washing is too long.

、电泳后水洗不充分。 2. Insufficient water washing after electrophoresis.

、槽液温度偏高。 3 , the bath temperature is too high.

、环境湿度低。 4. Low ambient humidity.

solutions:

、在副槽处增设UF0喷洗。 1. Add UF0 spray cleaning at the auxiliary tank.

、检查电泳后的水洗,及时更换新水,确保被涂物清洗完全。 2. Check the water washing after electrophoresis, and replace it with new water in time to ensure that the coating is completely washed.

、适当降低槽液温度。 3 , appropriately reduce the temperature of the bath.

、保持电泳车间相关区域地面一定的湿润度。 4. Maintain a certain degree of wetness on the floor of the relevant area of the electrophoresis workshop.
