Paper Machine High Polymer HDPE Doctor Blade

What is an HDPE Doctor Blade and Its Application？

The polymer HDPE doctor blade is made of high density polyethylene. Its durability and chemical resistance can be widely used in food processing, chemical industry, paper making and printing industries. In the paper making industry, it is mainly used to remove excess debris from the wet part of the paer machine, especially for parts that require chemical resistance and wear resistance.

On the paper machine, the HDPE doctor blade is used to remove debris accumulated on the rollers (soft cots, polyurethane rollers, etc.), keep the roller surface clean, keep the paper flat and improve the drying efficiency.

Advantages of Polymer HDPE Doctor Blade

• High wear resistance: HDPE material has good wear resistance and can maintain a long service life in a high friction environment.

• Corrosion resistance: HDPE material can resist a variety of chemical corrosion, suitable for use in acid and alkali chemical environments, and is not easy to erode.

• Low friction coefficient: The surface of the HDPE doctor blade is smooth, and the low friction coefficient can reduce surface wear and prompt scraping effect when used.

• Easy to clean: Because of its HDPE material, it is not easy to absorb water and debris, and cleaning and maintenance are relatively simple. This feature is very suitable for industries such as food processing that have relatively high cleaning conditions.
