Abstract
The invention discloses a piece of high-filtering precision filter paper of a filter for hemp pulp. The filter paper is prepared by the following materials by weight part: 95-100 parts of hemp pulp fiber, 10-12 parts of asbestos fiber, 2-4 parts of modified nacrite, 1-2 parts of modified nano montmorillonite powder, 0.3-.05 parts of water-soluble nano silica sol, 1-2 parts of nano titanium dioxide, 0.5-1 parts of nano calcium carbonate, 0.5-1 parts of sodium salt of carboxy methyl-cellulose, 0.05-0.12 parts of sodium pentachlorophenate, 1-2 parts of fatty alcohol polyoxyethylene ether sodium sulfate, and 0.25-0.48 parts of PAE wet strength agent. According to the materials adopted by the invention, the adsorbability of the piece of the filter paper is increased through adding the modified nacrite and the improved nano montmorillonite powder so as to improve the filtering precision.
Description
Technical field
The present invention relates to cleaner filter paper field, is exactly a kind of jute pulp high filtering precision filter paper of filter.
Background technology
In a system, with a kind of medium of porous, the solia particle in liquid or gas is removed, be called filtration, for the annex that completes such mission employing 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 has been widely used in every field.According to the kinds of fibers difference of composition filter paper, performance, the purposes of filter paper are also different, are useful on the common filter paper of general occasion, under high temperature glass fiber filter paper, also have ultra-clean by polypropylene filter paper etc.According to whether impregnation of filter paper, 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 uncured filter paper.
Along with filter require improve constantly, any by singly plant fibrous filter paper be all more and more difficult to meet use on requirement, so the filter paper being formed by multiple fiber combinations arises at the historic moment.In filter paper production, conventional fiber has wood fibre, chemical fibre, glass fibre etc.
