The coating of alu extrusion profiles is a useful method for us to maintain aluminum materials and improve the decoration effect. The quality of the decoration effect directly affects the price and sales of our products. Therefore, we should strictly control the coating quality in order to achieve a better frame. Aluminum profile output. What are the factors that affect the coating of alu extrusion profiles? We summarize the main factors of the coating quality of aluminum extrusion profiles. There are four main points. Let's take a look at them:
1. Environment
The interior of the coating room is required to be clean and clean, to achieve dust-proof, insect-proof and certain ventilation functions to ensure that the surface quality of the aluminum plate coating is not polluted. At the same time, the process conditions should be changed in time due to temperature changes.
2. Raw materials
Coatings and aluminum extrusions are the elements that most affect the coating quality in the coating process, because there is a color difference between batches of coatings, the fineness of the coatings is not enough and the coating rate is not high, and the coatings and solvents are poorly matched and delaminated. It will directly affect the coating effect and cause defects. The unevenness of the aluminum coil substrate, the uneven film thickness, and the poor edge deflection also directly affect the product quality and overall use. Therefore, when selecting raw materials, it should be strictly controlled.
3. Equipment
The coating line requires the coating equipment to be intact, the coating equipment needs to run smoothly, and there should be no horizontal and vertical chattering, and the coating rollers need to be finely ground. coating surface quality.
4. Process
The coating process of alu extrusion profiles is closely related to the quality of the coating, and it is required to control the relative line speed ratio of the coating roller, the paint roller, the metering roller and the substrate within a certain scale. It should be based on different systems and coating products. Set a certain viscosity scale for the coating to ensure the smooth progress of the coating and promote the improvement of product quality. The curing process of the coating and the control of the oven must be controlled according to the requirements, and must not be changed arbitrarily, otherwise it will seriously affect the coating product. Chromatic aberration and functionality.
