How to improve the wear resistance and scratch resistance of rubber products on the surface of AF spray coating machine!
The AF spray coating machine can effectively enhance the wear and scratch resistance of plastic by coating a special coating on the surface of the plastic. The specific characteristics are as follows:
1. The AF spray coating machine uniformly sprays AF coating material on the surface of plastic, which forms a tight and continuous protective film after curing. The film layer has low surface performance and can reduce the friction coefficient between external objects and the plastic surface. When sharp objects scratch, it is not easy to leave marks on the plastic surface. For example, when coating AF coating on the surface of plastic phone cases, keys and other sharp objects scratch during daily use, it can effectively prevent scratches from occurring.
AF spray coating machines usually contain some special components, such as organosilicon, nanoparticles, etc., which crosslink with each other during the coating curing process to enhance the hardness of the coating. The organic silicon component can form a stable silicon oxygen bond network structure, and the nanoparticles are uniformly dispersed in the coating,
playing a reinforcing role. If an AF coating containing nano silica particles is applied to the surface of plastic eyeglass frames, the hardness is significantly improved, making it more scratch resistant for daily wear.
During the production process of plastics, there may be micro defects such as grooves and pores on the surface, which can easily become the starting point for scratches. When the AF spray coating machine sprays, liquid AF coating can flow in and fill these defects, making the plastic surface smoother. The flat surface reduces stress concentration points, reduces the risk of local damage caused by excessive force during scratching, and enhances the overall wear and scratch resistance. For example, after AF coating treatment on the surface of plastic toys, scratches can be effectively reduced.
Before the AF spray coating machine starts working, it is often equipped with pre-treatment functions such as plasma cleaning. The plasma interacts with the plastic surface, introduces polar groups, increases surface roughness, and improves surface performance.
This greatly enhances the adhesion between the AF coating and the plastic surface, ensuring that the coating will not easily peel off or peel off during use. When the surface of plastic is rubbed or scratched, the coating can firmly adhere and continue to provide protection. For example, after AF coating treatment, plastic car interior parts can maintain good wear resistance even after long-term use.
The AF spray coating machine is suitable for a variety of plastic materials. Different plastics have different characteristics, such as polycarbonate (PC), acrylonitrile butadiene styrene copolymer (ABS), polyethylene terephthalate (PET), polyethylene (PE), and polypropylene (PP). The AF spray coating machine can form coatings on the surfaces of these materials,
effectively improving their surface hardness, enhancing wear resistance, and endowing PP products with anti fingerprint and anti oil pollution functions. After AF coating treatment, it is not only easy to clean, but also prevents scratches and maintains its appearance.
