Abstract
The invention discloses a preparation technology of filter paper for an air filter. The filter paper is prepared from the following materials in parts by weight: 50-55 parts of hemp pulp fiber, 30-35 parts of rice straw fiber, 10-12 parts of corn fiber, 1-2 parts of modified nano sepiolite powder, 2-4 parts of modified mineral powder, 1-2 parts of styrene-acrylic emulsion, 1-2 parts of sodium bentonite, 0.2-0.4 parts of polyacrylamide, 0.3-0.5 parts of monoammonium phosphate, 0.5-1 part of aluminium silicate, 1-2 parts of coconut monoethanolamide, and 0.4-0.6 parts of PAE (polyarylether) wet strength agent. The filter paper prepared by the preparation technology has the advantages of good water permeability, large filter area, small maximum aperture, high filter precision, good water tolerance and the like, has a stable performance index at a normal temperature under a high-temperature work condition, and has better effects of temperature resistance and filtering.
Description
Technical field
The present invention relates to the air filter field, exactly is the preparation technology that a kind of air filter is used filter paper.
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.
The chief component of air filter is filter core and casing, and wherein filter core is main filtration fraction, bearing the filtration work of gas, and casing is the external structure that necessary protection is provided for filter core.The job requirement of air filter is to bear high efficiency air-filtering work, not for Air Flow increases too much resistance, and can long time continuous working.
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.
Summary of the invention
The object of the present invention is to provide the high air filter of a kind of filtering accuracy preparation technology of filter paper.
Above-mentioned purpose realizes by following scheme:
