紙箱廠如何解決紙箱塌箱問題

1、要控制好原紙的使用

檢查瓦楞紙的施膠情況,原紙表面吸水性指標藥效。如果原紙表面施膠差,吸水性就會偏高,很容易手冷庫低溫、潮濕的環境影響,導致回潮,變軟,整理抗壓強度降低。

2、生產紙板時要控制紙板的水分含量

紙板的水分含量不可過多,因為水分大則紙板的硬度低,影響紙板的邊壓指數。在紙板加工過程中,單面機和雙面機工序上膠量不能過大。一旦上膠量大,紙板的楞形會變形,而瓦楞的形狀是直接影響紙板的邊壓的,邊壓降低,的抗壓強度也隨之降低。

3、紙板的粘合強度要大

粘合強度是瓦楞紙與里紙、面紙的粘合力。如果萬一出現紙板假粘,受壓后,面紙或里紙便會與瓦楞紙分離,那么的抗壓強度會直線下降。

4、生產環節中的間隙壓力控制要適中

尤其要注意糊箱機上糊的間隙壓力不能太小,雙面機,模切機上的太陽輪間隙壓力要控制在合理的范圍內,以避免將瓦楞形壓潰,影響紙板的抗壓強度。

5、使用潑水劑、防水光油等解決表面防水防潮問題。
