Plastic shell for daily necessitiesmaterial ingredient

It is generally made of plastic and requires PP plastic. Other plastics will react with acid and alkaline substances to produce other substances. The spring part of the clip should also be made of all plastic PP. Because the spring is often stressed, its material specifications are more stringent, and it needs to be thick and strong, so as not to withstand the tension and cause it to break.

Scope of application

All plastic clips are most widely used in the garment dyeing industry and the alumina electrolysis industry.

1. In the dyeing process of clothing fabrics, the industry usually clamps the fabrics with clips, and then soaks them with a mixture of acid or basic dyes and water. Because the clip is all plastic, it will not rust. Ordinary day clips with metal springs are prone to rust and stain clothing when they come into contact with the pharmaceutical industry, which makes it difficult to clean stains from clothing. Therefore, it is generally not recommended to be used in the clothing dyeing industry. Instead, all plastic clips without any metal are used as dyeing fixtures.

2. In the alumina production process, the aluminum plate is usually electrolyzed in an acid solution or soaked in an acid solution to thicken the natural oxide film or produce other passivation films. In these processes, the industry often needs to clamp the aluminum plate, and the fixture must be insulated and acid resistant, and will not react with the liquid during the electrolysis process, avoiding the waste of the electrolyte liquid on unnecessary fixtures, and Prevent the chemical liquid from producing other substances and being contaminated and affecting production. This requires non-electrolytic, acid-resistant all plastic clips. The clip material must be PP (polypropylene) plastic, otherwise other types of plastics may be corroded by acidic liquids.
