Do You Know About Epoxy Resin Doctor Blade?

Epoxy Resin Doctor Blade

• Material composition: It is based on epoxy resin and is reinforced with carbon fiber, ultra-high molecular weight polyethylene (UHMW-PE), or glass fiber. Some versions also include solid lubricants.

• Physical parameters: The standard width ranges from 65 to 120 millimeters, with a thickness between 1 and 10 millimeters. It supports customized production as needed.

• Technical advantages: It addresses the issues of corrosion, wear, and rust commonly found in traditional metal doctor blades. It has a low friction coefficient of 0.05, making it suitable for high-temperature environments (up to 350°C) and humid conditions.

Advantages of the Epoxy Resin Doctor Blade

• Wear resistance: The wear loss is only 0.03 grams per square meter, which is 7 to 8 times better than manganese steel. It has a significantly longer service life compared to cast iron materials.

• Self lubrication: It contains waxy components, eliminating the need for extra lubrication and reducing equipment energy consumption.

• Stability: It maintains its shape even with frequent use and is resistant to chemical corrosion, such as 20% sulfuric acid and 20% sodium hydroxide. Its water absorption rate is less than 6%.

• Health and safety: The surface is smooth and free from scaling, meeting food-grade contact standards and preventing secondary contamination.

Main Applications of the Epoxy Resin Doctor Blade

• Paper industry: Used in the dryer and press sections of paper machines to remove pulp residue and improve the smoothness of the paper surface.

• Chemical and metallurgical industries: Used as material bin liners or chute scrapers to manage abrasive materials like coal powder and slag.

• Environmental protection equipment: Used to scrape off adhesives and resist acid and alkali corrosion in sewage treatment and solid waste processing.
