Problems solved by technology

This method is inconvenient to operate, easily scratches the substrate, takes up a lot of space, and the substrate in contact with the backing plate must be cut off, resulting in a high scrap rate
Overseas also use coating method for packaging, the cost is huge

Embodiment 1

[0022] High-grade LCD screen panel interlayer paper production process, such as figure 1 : Add 420kg northern wood pulp board and 180kg cloth wide pulp board into the hydraulic disintegrator for disintegration. The speed of the hydraulic disintegrator is based on the pulp board being fully disintegrated, and the disintegration time is controlled at 20-25min; disintegration Finally, the slurry enters the slurry storage tank, the control liquid level is 1.8m, and the control concentration is 4.0%. The function of the slurry storage tank is to store the crushed slurry for grinding and beating; Grinding, 2# double-disc mill consisting of double-disc mill, repeat the above operation five times, and then make a slurry, measure the degree of knocking and wet weight each time the disc mill is passed, control the current of 1# disc mill to 120A, and the current of 2# disc mill to be 150~160A, the final measurement of pulping degree is 40~45°SR, wet weight is 3.0~3.5g; the slurry enters...

Abstract

The invention discloses a high-grade liquid crystal display panel intermediary paper production process. The process comprises the steps of adding north wood-pulp boards and Bratsk hardwood pulp boards into a hydraulic disintegrator to be disintegrated, and feeding sizing agents into a sizing agent storage pond after disintegration; feeding the sizing agent into a double-disk refiner, repeating the operation for five times to form sizes, and measuring the size beating degree and wet weight; feeding the sizes into a size forming pond, and adding wet strength agents diluted 5 times; feeding the sizes into a machine chest and a head box successively, and adding a dispersant solution into the sizes in the head box; performing screen filtering, squeezing dewatering on the sizes to be shaped, applying glue on the surface of a surface sizer, and performing drying through a dryer to produce products. Intermediary paper produced through the process is low in quantitation, good in bulk, fine and uniform in membrane surface, impurity-free, low in smoothness, small in smoothness two-side difference, provided with characteristics of oil resistance, water proofing, organic liquid resistance, mildew proofing and damp proofing and the like, free of linting and dusting and print-free and residue-free when the membrane is attached to a liquid crystal display panel.

Description

technical field [0001] The invention belongs to the production field of liquid crystal glass substrates, and relates to an interlayer film used on a liquid crystal glass substrate, in particular to a production process of an interlayer paper for a high-grade liquid crystal panel. Background technique [0002] At present, society has entered the era of highly developed electronic information. Various electronic products are popularized in all aspects of people's life and work. Mobile phones, computers, TVs, etc. have entered the era of large screens, and liquid crystal substrates have also developed from ordinary glass to TFT-LCD, TFT-LED and other high-resolution, high-visibility ultra-thin non-alkali glass. Liquid crystal glass is very different from ordinary glass, and packaging plays an important role in the liquid crystal glass substrate. The packaging function of the liquid crystal glass substrate is mainly an effective measure to avoid surface defects such as scratch...
