Problems solved by technology

At present, the most common engine air filter element is resin-impregnated pleated filter paper, which cannot be reused and has a short service life, while other filter element materials such as microporous filter paper materials, non-woven fabric materials, and composite filter materials are inferior in performance and cost. It is difficult to achieve the ideal level, therefore, how to get a better performance of the air filter element is a technical problem to be solved

Abstract

The invention discloses a wooden fiber filter core of a vehicle air filter, and relates to the technical field of filters. The preparing method of the wooden fiber filter core of the vehicle air filter comprises the following steps of 1, adopting treating fluid to treat fraxinus mandshurica fiber raw materials; 2, sucking treatment slurry; 3, grinding sheet-shaped sericite. The wooden fiber filtercore of the vehicle air filter has high filtering efficiency and long service life.

Description

technical field [0001] The invention belongs to the technical field of filter elements, and in particular relates to a wood fiber filter element of an automobile air filter. Background technique [0002] As an important part of the air intake system of the automobile engine, the quality of the automobile air filter directly affects the reliability and service life of the engine. At present, the most common engine air filter element is resin-impregnated pleated filter paper, which cannot be reused and has a short service life, while other filter element materials such as microporous filter paper materials, non-woven fabric materials, and composite filter materials are inferior in performance and cost. It is difficult to reach the ideal level, therefore, how to obtain a better performance of the air filter element is a technical problem to be solved. Contents of the invention [0003] The purpose of the present invention is to provide a wood fiber filter element for an auto...
