U-shaped paper corner guard is a kind of classification of paper corner guard. Because the shape of paper corner guard is like the shape of letter U, it is called U-shaped paper corner guard, and corresponding to this is L-type paper corner guard. Do you know the production process of U-shaped paper corner guard?

一般印刷U型纸护角的生产分为U型纸护角浆和造U型纸护角两个基本过程，制浆就是用机械的方法、化学的方法或者两者相结合的方法把植物纤维原料离解变成本色U型纸护角浆或漂白U型纸护角浆。

Generally, the production of U-shaped paper corner guard is divided into two basic processes: U-shaped paper corner guard pulp and u-paper corner guard. Pulping is to use mechanical method, chemical method or a combination of the two methods to separate plant fiber raw materials into natural U-shaped paper corner guard pulp or bleached u-paper corner guard pulp.

造U型纸护角则是把悬浮在水中的U型纸护角浆纤维，经过各种加工结合成合乎各种要求的U型纸护角页。

To make U-shaped paper corner guard is to combine the U-shaped paper angle guard pulp fiber suspended in water into U-shaped paper corner guard page after various processing.

造U型纸护角厂一般需贮存足够用4～6个月的原料，使原料在贮存中经过自然发酵，以利于制浆，同时保证U型纸护角厂的连续生产。经备料工段把芦苇、麦草和木材等原料切削成料片（供生产化学浆）或木断（供生产磨木浆），再把小片原料放到蒸煮器内加化学药液，用蒸汽进行蒸煮，把原料煮成U型纸护角浆，或把木断送到磨木机上磨成U型纸护角浆，也可经过一定程度的蒸煮再磨成U型纸护角浆。

In general, the U-shaped paper corner guard plant needs to store enough raw materials for 4-6 months, so that the raw materials can undergo natural fermentation during storage, which is conducive to pulping and ensure the continuous production of U-shaped paper corner guard plant. The raw materials such as reed, wheat straw and wood are cut into pieces (for the production of chemical pulp) or wood chips (for the production of wood grinding pulp) by the material preparation section, and then the small pieces of raw materials are put into the digester to add chemical solution, and steam is used for cooking. The raw materials are boiled into U-shaped paper corner guard pulp, or the wood is sent to the wood grinder to grind into U-shaped paper corner guard pulp, or after a certain degree of cooking, it can be ground into U-shaped paper corner guard Pulp.

然后用大量清水对U型纸护角浆进行洗涤，并通过筛选和净化把浆中的粗片、节子、石块及沙子等除去。再根据U型纸护角种的要求，用漂白剂把U型纸护角浆漂到所要求的白度，接着利用打浆设备进行打浆。

Then the U-shaped corner guard pulp was washed with a large amount of water, and the coarse pieces, knots, stones and sand in the pulp were removed by screening and purification. Then according to the requirements of U-type paper corner guard, bleach the U-shaped paper corner guard pulp to the required whiteness, and then use the beating equipment to beating.

然后在U型纸护角浆中加入改善U型纸护角张性能的填料、胶料、施胶剂等各种辅料，并再次进行净化和筛选，后送上造U型纸护角机经过网部滤水、压榨脱水、烘缸干燥、压光卷取，并进行分切复卷或裁切生产出卷筒U型纸护角和平板U型纸护角。如果生产要生产涂布印刷U型纸护角，则需要干燥中部或生产成卷筒U型纸护角后经涂布加工而实现。

Then, fillers, sizing agents and other auxiliary materials to improve the performance of U-shaped paper corner guard are added into the U-shaped paper corner guard pulp, and then purified and screened again. Finally, it is sent to the U-shaped paper corner guard machine for making U-shaped paper. After water filtration, press dehydration, drying in the dryer, calendering and coiling, and cutting and rewinding or cutting, the U-shaped corner guard and flat U-shaped corner guard are produced. If you want to produce coated printing U-shaped paper corner guard, you need to dry the middle or produce roll U-shaped paper corner guard after coating processing.

U型纸护角的成品看似简单，其实经过了非常复杂的制作流程，其中每个环节都不能出差错，这样才能确保U型纸护角制作厂家制作出的U型纸护角。

The finished product of U-shaped paper corner guard seems simple, but it has gone through a very complicated production process, in which no error can be made in each link, so as to ensure that the u-paper corner guard manufacturer can produce high-quality u-paper corner guard.
