Additives required for PE pipes
In order to guarantee or improve the product quality of PE pipes, relevant treatments must be done during the production and processing of the pipes, such as the need for additives during production. The presence of these additives can make the pipe's product performance better. Therefore, the additives will also affect and determine the product quality of the pipe to a certain extent. So today I will tell you what additives are needed for production and processing.
1. Hydrogen and some catalysts are used to control molecular weight. The slurry reactor is generally a stirred tank or a more commonly used large-scale annular reactor in which the slurry can be circulated and stirred. As soon as ethylene and comonomer come into contact with the catalyst, polyethylene particles are formed.
2. The addition of antioxidants can prevent degradation of PE pipes during processing and prevent oxidation during use.
3. Antistatic additives are used in PE pipes to reduce adhesion to dust and dirt.
4. Excellent weather resistance and UV resistance can be achieved by adding UV additives.
Although it is said that adding these additives can improve the performance of the pipe during the production and processing of PE pipes, it is necessary to strictly control the amount when adding, otherwise excessive addition will not only have no good effect, but instead Will lead to "chaos" in the performance of the pipe, resulting in poor pipe quality and production failure. Therefore, you must be cautious when adding additives, never add them at will.
