Some projectile returner products are difficult to use after corrosion, causing our looms to run obstacles, so how to prevent the corrosion of projectile returners, I would like to introduce several methods.

1. In the process of manufacturing projectile returners, corrosion-resistant materials that are less likely to react with surrounding media are added.

For example, in chromium, nickel-titanium, etc. in the air is not easy to oxidation, can generate dense printed gymnasium film, can resist acid, alkali, salt, and other corrosion, added to iron or copper, can be made into excellent anti-corrosion projectile returner. advantage of metal powder metallurgy can be the flexible ratio of various gold elements, and the use of adding different properties of metal powder to obtain excellent anti-corrosion performance of projectile returner.

2. Anti-corrosion by a coating method

Coating and spraying, plating, and chemical conversion films. A protective layer is made on the projectile returner surface to isolate the projectile returner from the corrosive medium, thereby reducing corrosion.

Coating is the coating of organic and inorganic compounds on the surface of projectile returner, commonly used methods are paint and plastic coating, spraying is the coating method which is applied to the surface of the coated object through a spray gun or disc atomizer, dispersed into uniform and fine droplets by pressure or centrifugal force, mainly divided into: electric arc spraying, plasma spraying, electrostatic spraying, hand red spraying, etc.; metal Plating is a process of using metal powder to form a coating on the surface of the workpiece, mainly including: electroplating, hot plating, spray plating, permeation plating, chemical plating, mechanical plating, vacuum plating, etc.; chemical transformation film is the use of chemical or electrochemical methods to make projectile returner surface to form a stable compound film layer, according to the media used in film formation, the chemical transformation film can be divided into oxide film, phosphate film, chromate film, chromate film, etc. phosphate film, chromate film, etc.

According to the substances that constitute the protective layer of the coating method, it can be divided into (1) non-metal protective layer: such as paint, plastic, glass fiber reinforced plastic, rubber, asphalt, enamel, concrete, enamel, rust-proof oil, etc. (2) metal protective layer: in projectile returner surface plated with a metal or alloy, as a protective layer to slow down the rate of corrosion. Used as a protective layer of metal usually has zinc, tin, aluminum, nickel, chromium, copper, cadmium, titanium, lead, gold, silver, palladium, rhodium, and various alloys.

3. Handling corrosive media of projectile returner

Treatment of corrosive media is to change the nature of the corrosive medium and reduce or eliminate the harmful components of the medium to prevent corrosion. This method can only be in the corrosion Media limited number of conditions, for the space-filled atmosphere, of course, can not deal with.

4. Electrochemical protection of projectile returner

The use of direct current to change the potential of the projectile returner, so that corrosion slowed down or stopped the protection method is called electrochemical protection. This type of protection method mainly has external power cathodic protection method, protector protection method, and anodic protection method three.

projectile returner corrosion is mainly the surrounding media action damage, in the projectile returner interface will occur in a variety of chemical or electrochemical reactions, we can isolate the surrounding media, the use of metal materials that do not easily react with the surrounding media to process, plating on the projectile returner surface, to achieve the effect of metal corrosion prevention. Projectile returner anti-corrosion methods are many, the above is a detailed projectile returner anti-corrosion method, I hope it will be helpful to you.
