Embodiment Construction

[0010] The present invention will be further described below in conjunction with specific examples.

[0011] Bleached softwood pulp and bleached hardwood pulp with low dust and low ash content are transported by chain plate at a ratio of 7:3 and pulped with softened water, deslagged by high-consistency slag remover, and beaten by double-disc refiner Finally, the slurry is stored in the slurry tank, and antifungal agent and reinforcing agent are added to it; the slurry passes through the high-level box, the low-concentration slag remover (slag removal), adds polyacrylamide and passes through the front pressure screen, and then The slurry is distributed on the net through the air-cushion headbox, pre-dehydrated by using ceramic dehydration chopping boards and vacuum couch rolls, and further processed by a vacuum pre-pressing roll, a four-roller three-nip composite press roll, a vacuum suction roll, and a glossy press roll. Dehydration; 5 groups of 36 Φ1500mm drying cylinders are...

Abstract

The invention relates to a glass backing paper production process. The papermaking speed is 250m/min to 350m/min, the production efficiency is high, an air-cushion pulp box and a ceramic dehydrating chopping board are adopted in a papermaking forming area, pulp is uniform to distribute, and the quality is stable; a primary vacuum pre-pressing, four-roller three-pressure-interval composite pressing, vacuum adsorption and moving and glazing pressing are adopted in a pressing and dehydrating area, the dryness of paper entering a drying cylinder is increased, and the loose thickness of the paper is not damaged; a drying part adopts five groups of drying cylinders, namely totally 36 drying cylinders with the diameter of 1500mm, a closing gearbox, a closed steam cover, a paper guiding rope, a surface glue application machine, a glaze pressing machine, a paper coiling machine, a re-coiling machine, a super glazing pressing machine and the like, so that the smoothness of a product is improved, picking and powder can be prevented from dropping, and the high stiffness requirement can be met.

Description

technical field [0001] The invention relates to the supporting field of flat panel display devices, in particular to a production process of glass spacer paper. Background technique [0002] With the manufacture of flat panel displays (various types of LCD screens) and related electrical products moving to China, the market competition has become increasingly fierce. At present, Central China, located in the hinterland of mainland China, has become an important gathering area for the domestic flat panel display industry, as well as an important production base and supporting industry gathering area for global liquid crystal subsequent modules. With the gradual implementation and commissioning of Foxconn Zhengzhou factory and Samsung Xi'an project, the large-scale and relatively complete flat panel display industry chain mainly formed by world-class Japanese, Korean and Taiwanese joint ventures has also gradually improved. At the same time, the state has issued a series of p...
