Description

technical field

[0001] The invention relates to the technical field of filter paper, in particular to a hydraulic oil filter element filter paper with cellulose improving the filtering efficiency. Background technique

[0002] Nowadays, our society is developing rapidly, and most enterprises will choose mechanical operation methods in the construction process. With the continuous improvement of science and technology, in terms of mechanical operation, enterprises have applied the construction method of mechatronics. During the use of machinery, no matter how carefully the operator installs and operates the equipment, it will inevitably cause varying degrees of pollution to the hydraulic oil. The maintenance of hydraulic oil will take a lot of time and money, so hydraulic oil has become a part of the mechanical use process. the most important part of the. During the use of the machine, the hydraulic oil is mainly used to penetrate other parts for operation. Due to the water...
