Abstract
The invention discloses a process for producing chlorine-free insulation paper. The process is characterized by comprising the steps of preparing into water, pulping, supplying pulp, dehydrating and the like, therefore, the insulation paper has the advantages of low electric conductivity, high insulation resistance, no deformation and good product uniformity. The process is especially applicable to electronic industries.
Description
Technical field:
The present invention relates to a kind of production technology of insulating paper, particularly a kind of production technology of not having the chlorine insulating paper.
Background technology:
At present, the insulating paper that China's electron trade is used all is to adopt the wood pulp insulating paper, has the chlorine element in the wood pulp insulating paper, thereby this paper electrical conductivity is too high, and insulaion resistance is obviously too little, the angularity of product modification under moist situation is serious, and the uniformity of product does not reach the technical merit requirement.
Summary of the invention:
Purpose of the present invention be exactly to provide that a kind of insulating paper conductance is low, insulaion resistance is big, the no chlorine insulating paper production technology of indeformable, product good evenness.
The object of the present invention is achieved like this, and a kind of no chlorine insulating paper production technology is characterized in that it is may further comprise the steps:
1, system water: running water is entered into water treatment machine enter purification, the chlorion in the water and other ionic species are removed, form no chlorine pure water.
2, slurrying: the pulpboard that will make insulating paper is put into and is added no chlorine pure water in the pulper again and carry out size degradation, pulpboard is 1: 15～24 with the amount ratio of no chlorine pure water, pulpboard behind the size degradation enters in the disc mill and finish grindes, make the pulp-water beating degree reach 22～24 degree, form the pulp-water of technological requirement.
3, for slurry: will finish grind good pulp-water and enter into head box, pulp-water is evenly distributed in the fourdrinier part.
4, dehydration: will enter into vacuum system attached to the pulp-water in the fourdrinier part and carry out first step dehydration, and make 40% above moisture content take off, and form half wet page this moment; This page breaks away from from fourdrinier part and enters into squeezer and carry out the second step dehydration, and have 10% above moisture content to be taken off this moment again; The page that squeezer comes out enters and carries out the dehydration of the 3rd step in the dryer, and the temperature of dryer is 115～135 ℃, forms the product that contains 6% moisture content this moment.
Water treatment machine of the present invention adopts the membrane technology treatment facility.
Prior art of the present invention has the following advantages:
Because adopted system water, slurrying, for processing steps such as slurry, dehydrations, the chlorion of water and other ion are removed, thereby the product of production do not have that the chlorion electrical conductivity is low, insulaion resistance is big, product is indeformable under the environment of humidity, the good evenness of product.
The specific embodiment:
Running water is entered into water treatment machine enter purification, the chlorion in the water and other ionic species are removed, form no chlorine pure water; The pulpboard of making insulating paper put into add no chlorine pure water in the pulper again and carry out size degradation, pulpboard is 1: 15～24 with the amount ratio of no chlorine pure water, pulpboard behind the size degradation enters in the disc mill and finish grindes, and makes the pulp-water beating degree reach 22～24 degree, forms the pulp-water of technological requirement; The pulp-water that correct grinding is good enters into head box, and pulp-water is evenly distributed in the fourdrinier part; To enter into vacuum system attached to the pulp-water in the fourdrinier part and carry out first step dehydration, and make 40% above moisture content take off, form half wet page this moment; This page breaks away from from fourdrinier part and enters into squeezer and carry out the second step dehydration, and have 10% above moisture content to be taken off this moment again; The page that squeezer comes out enters and carries out the dehydration of the 3rd step in the dryer, and the temperature of dryer is 115～135 ℃, forms the product that contains 6% moisture content this moment.
