What is the difference between spray painting and spray painting in Dalian metal and plastic spray painting knowledge?

Dalian metal and plastic spray painting knowledge, metal surface spray painting is a method to protect metals from oxidation and corrosion. The corrosion phenomenon that occurs around us refers to the damage, performance degradation, or deterioration of various materials under the combined action of chemical, electrochemical, and several physical factors in the environment. And painting on metal surfaces is an important means of maintaining metal corrosion resistance. A good spray coating protective layer maintains continuous and intact integrity, and when combined well, can become a barrier to inhibit the invasion of corrosive media.

In the spray painting process of plastics, nylon, PP and other plastics, as well as stainless steel, aluminum alloy, zinc alloy and other metal spray paints, have been widely used for surface coating, involving fields such as plastic toys, small appliances, electronic digital, 3C accessories, etc. In terms of metal substrates, they include water plating for bathroom products, spray painting for speaker screens, etc. Other plastic materials include TR90 material, PEI plastic steel eyeglass frame, TPE smart watch strap, and a series of industries. Below is an introduction to the difference between spray painting and spray painting.

1. Spray painting is better than spray painting for leveling

The solvents, additives, and molecular structures of resins used for spray painting are all of great help in leveling up. There is no spray coating, so it often has an orange stripe effect.

2. Spray paint repairable

During the painting process, any bumps or scratches caused by excessive air film can be repaired at any time, as the paint has the function of recoating. But spraying is not acceptable.

3. The flexibility (bending) of spray painting is better than that of spray painting

Spray painting can bend 1mm or even T-bend, while spray painting cannot.

4. The decorative value of spray painting is relatively rich

The appearance color of spray painting is dozens of times more than that of spray painting, and the same material can be made into different effects. For example, non-metallic materials such as plastic, wood, paper, cloth, leather, etc. can be made into aluminum effect.

Paint adhesion refers to the ability of the paint film to bond with the surface of the object being coated or between coatings. Adhesion is an important technical indicator in paint and a prerequisite for the paint film to possess a series of properties. A paint film with good adhesion is durable and has the required performance for use; Paint films with poor adhesion are prone to cracking and peeling, making them unusable.

The application of pre-treatment and surface treatment processes such as purification, degreasing, activation, and rust removal before painting and coating of Dalian metal surfaces can effectively improve the anti-corrosion and corrosion resistance performance of painted and coated metals. Production practice has proven that the anti-corrosion performance of spray painted metal coatings is greatly influenced by the quality of the pre-treatment of the substrate before coating. Effective degreasing, rust removal, or sandblasting before coating the metal (especially castings) surface can purify and activate the surface, ensuring good adhesion between the coating film and the substrate metal. This is very beneficial for improving the corrosion resistance of spray painted metal coatings.
