Description
Technical field
The present invention relates to the automobile filter field, exactly is a kind of fuel filter filter paper that contains modification infusorial earth.
Background technology
In a system, with a kind of medium of porous the solia particle in liquid or the gas is removed, be called filtration, for the annex of finishing such mission employing is called cleaner.Cleaner includes air filter, oil filter, fuel filter, is referred to as three filters.
As a kind of effective filter medium, filter paper has been widely used in every field.Different according to the kinds of fibers that forms filter paper, the performance of filter paper, purposes are also different, are useful on the common filter paper of general occasion, be used under the high temperature glass fiber filter paper, also have ultra-clean with polypropylene filter paper etc.According to filter paper impregnation whether, can be divided into two large classes, i.e. impregnation filter paper and non-impregnation filter paper.Impregnation filter paper is divided into again curing filter paper and non-curing filter paper.
Along with improving constantly of filter requiring, anyly plant fibrous filter paper and all more and more be difficult to satisfy requirement on using by single, so the filter paper that is formed by multiple fiber combinations arises at the historic moment.Fiber commonly used in the filter paper production has wood fibre, chemical fibre, glass fibre etc.
