Abstract
The invention discloses a kind of fuel filter filter paper containing modification infusorial earth, it is obtained by the raw material of following weight parts: wood pulp fibre 70-75, polyster fibre 45-50, modification infusorial earth 2-4, modified Nano feldspar in powder 1-2, Polyvinylacetate Emulsion Adhesive 1-2, nano titanium oxide 1-2, ammonium dihydrogen phosphate (ADP) 0.5-1, APP 0.5-1, alumina silicate 0.3-0.4, Tween-80? 1-2, PAE wet strength agent 0.3-0.5.The advantages such as gained filter paper of the present invention has good water permeability, filter area is large, maximum diameter of hole is little, filtering accuracy is high, water-tolerant, have stable performance indications, have good resistance to gentle filter effect under normal temperature and worst hot case.
Description
Technical field
The present invention relates to automobile filter field, is exactly a kind of fuel filter filter paper containing modification infusorial earth.
Background technology
In a system, removed by the solia particle in liquid or gas, be called filtration with a kind of medium of porous, the annex adopted for completing such mission is called cleaner.Cleaner includes air filter, oil filter, fuel filter, is referred to as three filters.
As the effective filter medium of one, filter paper is widely used in every field.Different according to the kinds of fibers of composition filter paper, performance, the purposes of filter paper are also different, have the ordinary filter paper for general occasion, under high temperature glass fiber filter paper, also have ultra-clean polypropylene filter paper etc.According to filter paper whether impregnation, two large classes can be divided into, i.e. impregnation filter paper and non-impregnation filter paper.Impregnation filter paper is divided into again solidification filter paper and uncured filter paper.
Along with improving constantly of filtering requirement, any requirement be all more and more difficult to by the fibrous filter paper of single on satisfied use, so arisen at the historic moment by the filter paper of multiple fiber combinations.The fiber that filter paper is commonly used in producing has wood fibre, chemical fibre, glass fibre etc.
Summary of the invention
