Spring is an indispensable thing in daily life, and its metal protective layer also has many choices. The general plating method is to obtain the metal protective layer by electroplating. In addition, there are non-metals that can be used to prevent the spring. Corrosion, improve appearance, some electroplating processes can also change the working performance of the spring, such as improving hardness, wear resistance, improving thermal stability, preventing radiation corrosion, etc. If the general buyer only considers the corrosion problem, the general spring production Manufacturers are recommended to choose electro-galvanized or cadmium plating.

1. What is the non-metallic spring protective layer?

(1) The non-metallic protective layer of the spring is to dip or spray a layer of organic substances on the surface of the spring, such as paint, asphalt, plastic, etc., to protect the spring from corrosion. The non-metallic protective layer has a thick film layer, good chemical stability, and good mechanical anti-corrosion effect, but the hardness is low, which is easy to be scratched and damaged, and the film layer is aging.

2. The paint used for the spring paint layer usually has the following types:

(1) Asphalt paint Asphalt paint has good water resistance, moisture resistance, and corrosion resistance, and is particularly excellent in acid resistance and good alkali resistance. But the adhesion, mechanical strength, and decoration are poor.

(2) Phenolic paint Phenolic paint is divided into two kinds of primer and topcoat. Phenolic primer has strong adhesion and good anti-rust performance, but the mechanical strength and gloss of the paint film are poor. The phenolic topcoat paint film is hard and has good gloss, but the weather resistance is poor, and the paint film is easy to turn yellow.

(3) In general, the paint layer can be used alone or as a colorant after phosphating. Sometimes, in order to classify according to the load, some springs are also painted with different colors to distinguish them. The specific type and grade of paint used should be determined according to the working environment.

If necessary, it should be indicated in the spring pattern.
