产品的主要特性:
一、定量低：该产品定量为150g/m2-180g/m2，同时纸张有较高的抗张强度，满足纸面石膏板生产的需要，为石膏板的生产节约纸张消耗，生产的石膏板非常平整，是高档石膏板生产的首选护面纸材料。
二、透气度高：产品透气度高，适应高车速石膏板生产线的需要，为石膏板生产线提高车速提供物质基础，有利于石膏板厂家增加产量和效益。
三、热水渗透良好：有利于石膏板生产时控制脱水，提高石膏板的平整性，减少低档板和废板的产生。
四、外观质量良好，在护面纸制浆生产中，增加热分散、脱墨漂白、逆向除砂等设备，提高石膏板产品外观质量。
五、层间结合和表面强度高，在护面纸生产过程中，增加层间喷淋淀粉等化工助剂，使护面纸层间结合和表面强度提高，从而减少了废板的产生。
Themain features of the product:
I.Low basis weight: The basis weight of this product is 150g / m2 to 180g / m2.At the same time, the paper has a high tensile strength, which meets the needsof paper gypsum board production, saving paper consumption for the productionof gypsum board. Flat, is the first choice of paper for the production ofhigh-grade gypsum board.
Second,high air permeability: The product has high air permeability, which meets theneeds of high-speed gypsum board production lines, and provides a materialbasis for gypsum board production lines to increase vehicle speed, which isbeneficial to gypsum board manufacturers to increase output and benefits.
Third,good penetration of hot water: It is beneficial to control dehydration duringthe production of gypsum board, improve the flatness of gypsum board, andreduce the generation of low-grade boards and waste boards.
Fourth,the appearance quality is good. In the production of face paper pulp, equipmentsuch as thermal dispersion, deinking and bleaching, and reverse sand removalare added to improve the appearance quality of gypsum board products.
V.Interlayer bonding and high surface strength. During the production of facialpaper, chemical additives such as interlayer spray starch are added to increasethe bonding and surface strength of the protective paper, thereby reducing thegeneration of waste boards.
