Problems solved by technology

However, since both phenolic resin molecules and fiber molecules have hydrophilic groups -OH hydroxyl groups, when the filter element made of this filter paper filters water-containing diesel oil, water easily penetrates the filter element and enters the fuel injection pump and fuel injection nozzle, causing damage. Internal components that make diesel engines malfunction

Abstract

This invention discloses a chemical modifying method for an oil-water separation filter paper core which chemically modifies the product core only and the core is produced by traditional technology. (1) The chemical aids includes the following components: A 100 portions of hydrophilic oleo phobic organic silicon resin, B, silane couler; 2-6, C matching A+B with absolute alcohol to a dipping mix containing 5-20% net weight of A, (2) The filter paper modifying process technology is: A. dipping the core, B blowing compressed air, C drying.

Description

technical field [0001] The invention belongs to the technical field of fuel and diesel filters for automobiles, and specifically relates to a method for chemically modifying filter paper cores for filters. Background technique [0002] At present, a new type of high-efficiency oil-water separation fuel and diesel filter produced by foreign companies with dual functions of filtering impurities and separating oil and water has been widely used in domestic diesel engines. It can separate impurities while filtering impurities in oil. The advantages of the free water contained in the oil and the emulsified water formed by high-speed mechanical movement are mainly reflected in: ①It can slow down the rust and corrosion of the high-pressure oil pump and the fuel injection nozzle, thereby greatly improving the life of the whole machine (because the oil contained in the oil Containing water and SO after diesel combustion 2 combined to form H 2 SO 4 Corrosio...
