Cellulose filter paper capable of increasing filter efficiency and used for hydraulic oil filter element

Abstract

The invention discloses a hydraulic oil filter element filter paper with cellulose to improve the filtration efficiency, which is prepared from the following raw materials in parts by weight: 50-55 mm of alkali-free ultrafine glass fiber of 3-5 mm, 55-60 mm of bleached coniferous wood pulp, and distilled water Appropriate amount, 0.8-1 of anionic polyacrylamide, appropriate amount of concentrated sulfuric acid with a concentration of 98wt%, 10-12 nanometer titanium dioxide, 20-25% of ferric oxide colloidal solution with a solid content of 30%, appropriate amount of anhydrous ethanol, and a solid content of 40wt% Fluorosilicone emulsion 60-65, cellulose micropowder 6-7, 4mol / L sodium hydroxide solution 8-9, dimethyl silicone oil 1.5-2, organic tin laurate 0.4-0.45, dolomite 3-4, seaweed Sodium acid 0.9-1.1. The filter paper made by the invention is firm and tough, not easily damaged, has a long service life and prolongs the replacement time.

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...
