Common Problems and Solutions for Pre-treatment Equipment: Key Steps to Ensure Coating Quality

Pre-treatment equipment plays a vital role in the coating industry, they are responsible for treating the surface of the workpiece and preparing it for subsequent coating work. However, problems are often encountered during the use of pre-treatment equipment. In this article, we will analyze the common problems of pretreatment equipment and provide solutions to ensure the critical step of painting quality.

I. Common problems and solutions for cleaning equipment:

Poor cleaning effect: It may be caused by insufficient concentration of cleaning liquid or insufficient cleaning time. The solution is to adjust the concentration of the cleaning solution and the cleaning time according to the characteristics of the workpiece and the degree of contamination to ensure thorough cleaning.

Pollution of the cleaning fluid: The cleaning fluid may be polluted during use, resulting in a decrease in the cleaning effect. The solution is to regularly replace the cleaning fluid and keep it clean.

Cleaning equipment clogging: Pipes and nozzles in the cleaning equipment may be clogged, affecting the cleaning results. The solution is to regularly clean the pipes and nozzles in the equipment to ensure a smooth flow.

II. Common problems and solutions for rust removal equipment:

Poor descaling effect: It may be caused by insufficient concentration of descaling agent or insufficient treatment time. The solution is to adjust the concentration of the descaling agent and the treatment time according to the degree of corrosion of the workpiece to ensure that the corrosion is completely removed.

Improper selection of descaling agent: Different types of descaling agents are suitable for different rust and corrosion conditions, and improper selection may lead to poor descaling effect. The solution is to select the appropriate descaling agent for treatment according to the degree of rusting on the surface of the workpiece and the characteristics of the material.

Damage to rust removal equipment: The rust removal equipment may malfunction or be damaged in the course of use, affecting the rust removal effect. The solution is to check and maintain the descaling equipment regularly and repair or replace the damaged parts in time.

III. Common problems and solutions for surface treatment equipment:

Uneven surface finish: This may be caused by uneven spray pressure or clogged nozzles. The solution is to adjust the spraying pressure to ensure even spraying and clean the nozzle regularly to avoid clogging.

Improper selection of surface treatment agents: Different types of surface treatment agents are suitable for different workpiece surface treatment needs, and improper selection may lead to poor treatment results. The solution is to choose the appropriate surface treatment agent according to the material and treatment requirements of the workpiece.

Temperature control of surface treatment equipment: Some surface treatment equipment requires temperature control to ensure the treatment effect. The solution is to adjust the temperature control of the equipment according to the requirements of the workpiece and the surface treatment agent to ensure the stability of the treatment effect.

Pre-treatment equipment plays a vital role in the coating process. By solving common problems with cleaning equipment, descaling equipment and surface treatment equipment, you can ensure a critical step in painting quality. 

OURS COATING hopes that the above analysis of common problems and solutions of pretreatment equipment can help you operate the equipment better and improve the coating quality.
