U型紙護角是紙護角的一種分類，由于紙護角的形狀就像字母U的形狀，因而被稱為U型紙護角，與此對應的還有L型紙護角。那么U型紙護角的制作流程你都清楚嗎？
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型紙護角的生產(chǎn)分為U型紙護角漿和造U型紙護角兩個基本過程，制漿就是用機械的方法、化學的方法或者兩者相結合的方法把植物纖維原料離解變成本色U型紙護角漿或漂白U型紙護角漿。
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型紙護角則是把懸浮在水中的U型紙護角漿纖維，經(jīng)過各種加工結合成合乎各種要求的U型紙護角頁。
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型紙護角廠一般需貯存足夠用4～6個月的原料，使原料在貯存中經(jīng)過自然發(fā)酵，以利于制漿，同時保證U型紙護角廠的連續(xù)生產(chǎn)。經(jīng)備料工段把蘆葦、麥草和木材等原料切削成料片（供生產(chǎn)化學漿）或木斷（供生產(chǎn)磨木漿），再把小片原料放到蒸煮器內(nèi)加化學藥液，用蒸汽進行蒸煮，把原料煮成U型紙護角漿，或把木斷送到磨木機上磨成U型紙護角漿，也可經(jīng)過一定程度的蒸煮再磨成U型紙護角漿。
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.
然后用大量清水對U型紙護角漿進行洗滌，并通過篩選和凈化把漿中的粗片、節(jié)子、石塊及沙子等除去。再根據(jù)U型紙護角種的要求，用漂白劑把U型紙護角漿漂到所要求的白度，接著利用打漿設備進行打漿。
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型紙護角漿中加入改善U型紙護角張性能的填料、膠料、施膠劑等各種輔料，并再次進行凈化和篩選，后送上造U型紙護角機經(jīng)過網(wǎng)部濾水、壓榨脫水、烘缸干燥、壓光卷取，并進行分切復卷或裁切生產(chǎn)出卷筒U型紙護角和平板U型紙護角。如果生產(chǎn)要生產(chǎn)涂布印刷U型紙護角，則需要干燥中部或生產(chǎn)成卷筒U型紙護角后經(jīng)涂布加工而實現(xiàn)。
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型紙護角的成品看似簡單，其實經(jīng)過了非常復雜的制作流程，其中每個環(huán)節(jié)都不能出差錯，這樣才能確保U型紙護角制作廠家制作出的U型紙護角。
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.
