Abstract
The invention aims at providing hot pressing tympan paper, in particular to hot pressing tympan paper, which replaces kraft paper to be used as buffer materials in the pressing process of paper used in electronic industry. The hot pressing tympan paper has the wood pulp raw material composition comprising 65 to 75 percent of softwood pulp and 35 to 25 percent of nature color bamboo wood pulp. The softwood pulp and the nature color bamboo wood pulp are prepared into paper, and the preparation is carried out according to the following steps: (1) mixed pulping: carrying out pulping after the softwood pulp and the nature color bamboo wood pulp are proportionally mixed and crushed, controlling the pulping current between 50 to 60 A, and controlling the pulp forming beating degree between 25 to 30 degrees SR; (2) pulp preparation: carrying out sand removal and slag removal; and (3) carrying out stir-frying by a three-screen multi-cylinder paper machine at a baking cylinder air pressure between 2 and 3 Kg/cm<2>, and controlling the paper thickness at 0.29+/-0.02mm. The invention adopts the softwood pulp and the nature color bamboo wood pulp for preparing the hot pressing tympan paper to replace the ordinary kraft paper to be used as the buffer materials in the pressing process of the paper used in the electronic industry, the requirements of high temperature resistance and ventilation can be met, and in addition, the heat transfer speed rate is uniform, so the pressed products have stable quality and high finished product yield.
Description
Technical field
The invention belongs to pulp technology for making paper, particularly the manufacturing of used in electronic industry paper.
Background technology
For a long time, suppress on hot press in the process of insulation board, copper foil plate and multilayer circuit board, the padded coaming in the middle of heat transfer plate and the presed-steel plate substitutes with common brown paper always, lacks special-purpose padded coaming.Because common brown paper does not possess characteristics such as high temperature resistant in the hot pressing, rate of heat transfer unanimity, the product quality that makes compacting come out is very unstable, and yield rate is very low.
Summary of the invention
The object of the invention provides a kind of hot pressing tympan paper, to substitute brown paper as padded coaming in the used in electronic industry letterweight system process.
Specifically, hot pressing tympan paper, its raw material of wood pulp consist of softwood pulp and the 35-25% true qualities bamboo wood pulp of 65%-75%, make paper.
The preparation technology of described hot pressing tympan paper is characterized in that implementing according to following steps:
(1) mix making beating: softwood pulp and true qualities bamboo wood pulp are mixed the making beating of broken back in proportion, and the making beating Current Control is at the 50-60 ampere, and the pulping beating degree is controlled at 25-30 ° of SR
(2) join slurry: desanding, slagging-off;
(3) with three net multi-cylinder paper machines system of copying and drying cylinder air pressure 2-3Kg/cm
2, paper sheet thickness is controlled at 0.29 ± 0.02mm.
The present invention adopts softwood pulp and true qualities bamboo wood pulp mixed pulp to prepare hot pressing tympan paper and substitutes common brown paper as padded coaming in the used in electronic industry letterweight system process, can satisfy high temperature resistant and ventilative requirement, and rate of heat transfer unanimity, the constant product quality that feasible compacting is come out, the yield rate height.
The specific embodiment
Hot pressing tympan paper, its raw material of wood pulp consist of 70% softwood pulp and 30% true qualities bamboo wood pulp, make paper.
The preparation technology of described hot pressing tympan paper, it is to implement according to following steps:
(1) mix making beating: softwood pulp and true qualities bamboo wood pulp are mixed the making beating of broken back in proportion, and the making beating Current Control is at the 50-60 ampere, and the pulping beating degree is controlled at 25-30 ° of SR
(2) join slurry: desanding, slagging-off;
(3) with three net multi-cylinder paper machines system of copying and drying cylinder air pressure 2-3Kg/cm
2, paper sheet thickness is controlled at 0.29 ± 0.02mm.
Claims (3)
1. hot pressing tympan paper is characterized in that raw material of wood pulp consists of softwood pulp and the 35-25% true qualities bamboo wood pulp of 65%-75%, makes paper.
2. hot pressing tympan paper according to claim 1 is characterized in that raw material of wood pulp consists of softwood pulp and the 30% true qualities bamboo wood pulp of 70%-, makes paper.
3. the preparation technology of hot pressing tympan paper as claimed in claim 1 or 2 is characterized in that implementing according to following steps:
(1) mix making beating: softwood pulp and true qualities bamboo wood pulp are mixed the making beating of broken back in proportion, and the making beating Current Control is at the 50-60 ampere, and the pulping beating degree is controlled at 25-30 ° of SR
(2) join slurry: desanding, slagging-off;
(3) with three net multi-cylinder paper machines system of copying and drying cylinder air pressure 2-3Kg/cm
2, paper sheet thickness is controlled at 0.29 ± 0.02mm.
