Super-hydrophobic sterilization type hydraulic filter paper for filters

Abstract

The invention discloses super-hydrophobic sterilization type hydraulic filter paper for filters. The super-hydrophobic sterilization type hydraulic filter paper comprises, by weight, 50-55 parts of alkali-free ultrafine glass fibers with the sizes of 3-5 millimeters, 55-60 parts of bleached needle-point leaf wood pulp, an appropriate quantity of distilled water, 0.8-1 part of anionic polyacrylamide, an appropriate quantity of concentrated sulfuric acid with the concentration of 98 wt%, 10-12 parts of nanometer titanium dioxide, 20-25 parts of ferriferous oxide colloidal solution with the solid content of 30%, an appropriate quantity of absolute ethyl alcohol, 60-65 parts of fluorine-silicon emulsion with the solid content of 40 wt%, 6-7 parts of carbon alginate, 0.9-1 part of silver chloride, 1-2 parts of vinyltriethoxysilane, 2-3 parts of silica sol and 0.3-0.4 part of tributyl phosphate. The super-hydrophobic sterilization type hydraulic filter paper has the advantages that the super-hydrophobic sterilization type hydraulic filter paper has uniformly distributed dense pores and is excellent in adsorbability, and processes for the super-hydrophobic sterilization type hydraulic filter paper are convenient to industrially control and easy to implement.

Description

technical field [0001] The invention relates to the technical field of filter paper, in particular to a filter paper for a superhydrophobic and sterilizing hydraulic filter. 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, gas and dust mixed in...

Problems solved by technology

However, the filter paper used in this article is ordinary filter paper, which does not have good high temperature aging resistance and corrosion resistance, and the filter paper will be damaged under pressure for a long time, resulting in filter failure, which will directly increase the production cost, and should be developed. A filter paper that can be easily replaced, not only can resist a certain pressure, has good strength, can be used in high temperature oil, but also can filter the moisture in the hydraulic oil and the mechanical impurities in the system, etc., at the same time save costs
