PE ultrafine powder

Introduction to PE ultrafine powder

PE ultrafine powder is a fine powder, made of polyethylene (PE), its main feature is that the powder fineness is very high, usually can reach the sub-micron level, with strong dispersion and tensile properties, can be used to manufacture high-performance materials and products, widely used in modern industrial production.

Manufacturing method of PE ultrafine powder

The manufacturing methods of PE ultrafine powder are various, and the commonly used methods are chemical method, physical method and mechanical method.

Chemical method: The chemical method is a method of breaking PE polymer chains into small molecules, usually using chemical reactants to eliminate the bonds between PE molecules, so that PE molecules are broken into small molecules. The advantage of this method is that the production cost is low, but it will cause pollution problems and need to be treated environmentally.

Physical method: The physical method is to use high-energy electron beam or laser beam to radiate PE film into narrow, thin bands, and then use mechanical method to crush these bands into ultrafine powder. This method does not require any chemical reactants, and no pollutants are produced in the manufacturing process, but the production cost is high.

Mechanical method: The mechanical method mainly uses small crushing equipment (such as spray dryers, ball mills, etc.) to decompose the PE polymer chain into tiny particles through mechanical friction. This method has low production costs, but because mechanical friction generates a lot of heat, the resulting powder needs to be cooled.

Application of PE ultrafine powder

PE ultrafine powder is widely used in various manufacturing fields, such as: tires, plastics, coatings, glue and other industries have applied PE ultrafine powder.

1. Tire field: PE ultrafine powder can be filled on the tire fender, because of its high fineness, it can greatly reduce the resistance and air resistance generated by the fender.

2. Plastic field: PE ultrafine powder can be used to manufacture high-performance plastics, such as impact resistant plastics and high-strength plastics.

3. Coating field: PE ultrafine powder can be used to manufacture high-strength and high-toughness coatings, making the coating more robust and wear-resistant.

4. Glue field: PE ultrafine powder can be used to manufacture high strength and high toughness glue, such as can be used for automotive glass bonding and building materials bonding.

Market prospect of PE ultrafine powder

PE ultrafine powder market prospects are very broad, the future demand for high-performance materials and products will continue to increase, PE ultrafine powder as a functional powder, has a wide range of application prospects in various fields. The popularization of artificial intelligence and the continuous upgrading of mobile phone demand will play an important role in promoting the development of the ultra-fine powder industry. Due to the wide application field of PE ultrafine powder, the market demand is also very large, and the ultrafine powder manufacturing industry will have broad development prospects.
