1、普通250g/㎡掛面箱紙板水分于8%時，紙護角開始爆裂。
1. When the moisture content of ordinary 250G / ㎡ vermicelli cardboard is lower than 8%, the paper corner guard begins to burst.
2、耐折性能非常好的牛皮箱紙板水分含量于6%時，紙護角紙護角開始爆裂。
2. When the moisture content of kraft linerboard with very good folding resistance is less than 6%, the paper corner protector begins to burst.
3、保持紙板水分對防止紙板爆裂非常重要。
3. Keeping water in the cardboard is very important to prevent the cardboard from bursting.
紙板爆裂的控制辦法：
Control method of cardboard bursting:
保持紙護角的水分含量是控制紙板爆裂的辦法，從瓦線出來的瓦楞紙水分含量控制在12%--18%之間是比較合理的，由于受一些客觀條件的限制，人們往往認(rèn)為控制紙板水分不太容易。
Keeping the moisture content of the paper corner guard is the way to control the bursting of the paperboard. It is reasonable to control the moisture content of the corrugated paper from the tile line between 12% - 18%. Due to the limitations of some objective conditions, people often think that it is not easy to control the moisture of the paperboard.
測試表明，天氣干燥季節(jié)，紙板剛從紙板線出來時面紙水分含量在8%左右，有的甚于6%，瓦楞紙紙護角當(dāng)紙板堆放四小時后，各層的水分趨于平衡，面紙水分增加到9%以上，因此，若紙板剛從瓦線出來就上機印刷，由于此時面紙水分很，容易導(dǎo)致壓線位爆裂，所以紙板生產(chǎn)出來后要堆放足夠的時間，到各層的水分平衡后再印刷，紙板面、里水分偏即進行印刷，壓線部位會產(chǎn)生微裂，此后，即使面、里水分增加爆線問題也不可能避免。
The test shows that in the dry season, when the paperboard just comes out of the paperboard line, the moisture content of the face paper is about 8%, and some are even lower than 6%. When the paperboard is stacked for four hours, the moisture of each layer tends to balance, and the moisture of the face paper increases to more than 9%. Therefore, if the paperboard is printed on the machine just after coming out of the paperboard line, the moisture content of the face paper is very low, which is easy to lead to the burst of the pressing position, Therefore, after the paperboard is produced, it should be stacked for enough time, and then printed after the water balance of each layer. When the water on the surface and inside of the paper board is low, printing will be carried out, and micro cracks will occur at the pressing part. After that, even if the water on the surface and inside increases, the wire burst problem can not be avoided.
這樣既浪費時間也達(dá)不到佳的效果避免不了紙板的爆裂，針對此情況，建議在生產(chǎn)過程中使用加濕器進行局部或者整體加濕。這樣既避免了堆放導(dǎo)致的時間浪費，也解決了水分偏導(dǎo)致的暴線問題。
This is not only a waste of time, but also can not achieve the best effect, and can not avoid the bursting of paperboard. In view of this situation, it is recommended to use humidifier for local or overall humidification in the production process. This not only avoids the waste of time caused by stacking, but also solves the problem of line burst caused by low moisture.
