Problems solved by technology

The high-end PS plate lining paper is mainly imported (mainly France, accounting for about 40% of the domestic market capacity), and some domestic paper companies in Shandong have begun to produce PS plate lining paper, but due to poor equipment level and production control level, Compared with imported products, there is still a certain gap in the quality of domestic PS plate liners

Embodiment 1

[0015] Example 1: 30 grams of PS plate backing paper

[0016] The coniferous wood pulp (the degree of beating is controlled at 65-70 0 SR) and hardwood pulp (the degree of beating is controlled at 55-60 0 SR) The two kinds of pulp are prepared according to the ratio of 30%:70%, adding 0.30~0.5kg / ton of paper retention aid, adding 0.5~0.7 kg / ton of paper defoamer, adding 20~30 kg / ton of paper Iron-free aluminum sulfate, etc., the prepared cost-white diluted pulp is online, and double-sided dehydration is carried out by overlapping the screen to ensure that the fibers are evenly dispersed, and the vertical and horizontal fibers are arranged in an orderly and uniform distribution. After the wet paper sheet is fed into the press section for compound pressing; The paper sheets that are pre-dried to 95% dryness enter the sizing section, and the surface sizing treatment (surface sizing starch) is carried out on the paper by film transfer method; the amount of sizing on one side is c...

Abstract

The invention discloses a production method of PS plate interleaving paper. The production method comprises the process steps as follows: respective beating of softwood pulp and hardwood pulp, pulp blending and addition of auxiliary materials, wet paper sheet making, pre-drying, surface sizing, after-drying, calendaring and finishing. Through research of pulp selection, pulp proportioning, a beating process and addition of functional chemical assistants to the pulp, adoption of film transfer surface sizing treatment as well as integration of finishing measures such as a soft calendaring equipment and the like, production of qualified PS plate interleaving paper is executed according to related paper machine parameters, and the method has great significance in optimization of product structure for a company and improvement of profitability of the company.

Description

technical field [0001] The invention relates to a method for manufacturing PS plate backing paper, belonging to the technical field of papermaking. Background technique [0002] PS plate lining paper is a kind of liner paper mainly used in the production of PS plate and CTP plate. The PS plate is composed of photosensitive coating and support plate base. With the popularization of lithography and the extensive use of treatment-free CTP plates, it brings convenience to plate making and eliminates the need for plate development, fixing, and cleaning chemicals. , After the PS plate is exposed and imaged on the direct-to-plate equipment, it can be put on the machine without any follow-up processing. The PS plate backing paper can prevent the photosensitive layer of the PS plate from falling off due to the coating layer due to moisture, prevent the photosensitive layer from being scratched and scratched, and reduce the staining of the printing plate. Require. The raw material ...
