怎么增強紙箱的硬度?

來源:http://www.xmntn.com 時間:2019-11-13

在如今很多行業都需要使用紙箱,但是如果是硬度不好的話,用紙箱裝盛比較的物品就會很容易出現變形或者嚴重損壞。那么應該如何增強濟南紙箱的硬度呢?
Nowadays, many industries need to use cartons, but if the hardness is not good, the items packed in cartons for comparison will be easily deformed or seriously damaged. So how to enhance the hardness of Jinan carton?
1、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。有時,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 a variety of 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 corrugated box. These include additives such as corn, starch, gum, adhesives and heavy metals, as well as plastics and urea formaldehyde resins. In some cases, chemical spraying on the outer layer of cartons is also used to strengthen fiberboard.
2、高壓
2, high voltage
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 paper board forming is also a way to enhance the strength of paper board in the paper-making process. The paper board is tightly compressed by enlarging the compression point on the paper fiber. The closer the structure of cardboard, the stronger the strength. High pressure paperboard forming also helps to extrude more water from the pulp, but the key is to make a more compact paperboard and improve its compressive strength.

3、交聯
3. 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,這種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 process that changes the direction of fibers in the process of papermaking. Generally, the paper fiber is parallel in longitudinal direction. After the box is formed, the fiber is horizontally around the box, which is the bad direction that causes the box to resist the pressure. As a result, many fibers are perpendicular to the box edge, so that the stacking strength of cartons can be increased without increasing the fibers.
4、層合
4. Lamination
這種增強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。
This method to enhance the strength of corrugated box is based on two or more layers; the core paper is laminated. The adhesive can be a simple corn starch adhesive that produces a strong core paper to be sandwiched between cross-linked, pressure formed, or conventional strength paper.
