重型瓦楞紙箱的硬度應該如何提高?

來源:http://www.wikeloogle.com 時間:2021-04-23

一、添加劑:
1、 Additives:
這種方法就是在造紙前和造紙后向纖維中添加各種化學晶,用于提高纖維的粘結力,從而提高重型瓦楞紙箱的抗壓強度。這些添加劑包括如玉米、淀粉、膠、粘合劑和重金屬,及塑料和脲(甲)醛樹脂。也采用化學品噴涂紙箱外層的方法來加強纖維紙板。
This method is to add various chemical crystals to the fiber before and after papermaking to improve the adhesion of the fiber, so as to improve the compressive strength of the heavy corrugated box. These additives include corn, starch, gum, adhesives and heavy metals, as well as plastics and urea formaldehyde resins. Chemical spraying is also used to strengthen the fiber board.
通常來說,用化學添加劑比交聯法或其他方法費用要一些,但是當它們的使用成本大于用增加板和芯紙重量的方法,制成更堅實的紙箱時,那它們就沒有意義了。
Generally speaking, the cost of using chemical additives is lower than that of cross-linking or other methods, but when the cost of using them is greater than that of making stronger cartons by increasing the weight of the base plate and core paper, they are meaningless.
二、高壓:
2、 High pressure:
高壓紙板成形法也是一種在造紙過程中增強紙板強度的方法。采用擴大紙纖維上的受壓點來緊密地壓縮紙板。而紙板結構越緊密,強度就越大。高壓紙板成形也有助于從紙漿中擠出更多的水分,但是關鍵是要制成更緊密的紙板,提高其抗壓強度。
High pressure paperboard forming is also a method to enhance the strength of paperboard in papermaking process. Expand the compression point on the paper fiber to compress the paperboard tightly. And the closer the paperboard structure, the greater the strength. High pressure paperboard forming also helps to extrude more water from the pulp, but the key is to make more compact paperboard and improve its compressive strength.

三、層合:
3、 Lamination:
這種增強重型瓦楞紙箱強度的方法是建立在兩層或更多層;芯紙層合的基礎上的。粘合劑可以是一種簡單的玉米淀粉粘合劑,產生一種強度的芯紙以夾在交聯的、加壓成形的或常規強度的紙中間。雙芯重型瓦楞紙箱保持著的單瓦楞結構,卻起著重型瓦楞紙箱的作用,它比單重型瓦楞紙箱重約百分之十,但產生的抗壓強度大大提高百分之十。雙芯紙箱還具有更大的環壓強度,同時增加了紙箱抗壓強度,在托盤堆碼三個以上高度時起了重要的作用。
This method of strengthening the strength of heavy corrugated box is based on two or more layers; The core paper is based on lamination. The binder can be a simple corn starch binder that produces a strength core paper to be sandwiched between cross-linked, pressure formed or conventional strength paper. The double core heavy-duty corrugated box keeps the single corrugated structure, but it plays the role of heavy-duty corrugated box. It is about 10% heavier than the single heavy-duty corrugated box, but the compressive strength is greatly improved by 10%. The double core carton also has greater ring compression strength, and increases the compressive strength of the carton, which plays an important role in the stacking of pallets with more than three heights.
四、交聯:
4、 Crosslinking:
交聯是一種在造紙過程中改變纖維方向的加工方法。通常紙纖維是縱向平行走向的,這樣箱子成型后纖維水平方向圍繞在箱子周圍,而這是造成紙箱抵抗壓力的的壞方向。交聯則使許多纖維與機器方向呈90度走向,加工結果是許多纖維與箱邊上下垂直走向,這樣就能不增加纖維而增加了紙箱堆碼強度。
Crosslinking is a processing method to change the direction of fiber in papermaking process. Usually, the paper fibers are parallel in the longitudinal direction, so that the fiber horizontal direction around the box after the box forming, which is the bad direction of the box resistance to pressure. Crosslinking makes many fibers and machine direction is 90 degrees, the processing result is that many fibers and box edge up and down vertical direction, so that can not increase the fiber and increase the stacking strength of the carton.
以上就是常見的幾種提高重型瓦楞紙箱硬度的方式,一般在進行定制的時候,可以根據需要包裝物品的情況來進行增加重型瓦楞紙箱硬度的方式。好了,今天的分享就到這里了,關于重型瓦楞紙箱的定制,歡迎大家咨詢網站哦:重型瓦楞紙箱廠家http://www.wikeloogle.com!
The above are several common ways to improve the hardness of heavy-duty corrugated boxes. Generally, when customizing, you can increase the hardness of heavy-duty corrugated boxes according to the needs of packaging. Well, that's all for today's sharing.
