重型瓦楞纸箱的硬度应该如何提高?

来源:http://www.shuangfengbaozhuang.cn 时间:2021-04-23

一、添加剂:
1、 Additives:
这种方法就是在造纸前和造纸后向纤维中添加各种化学晶,用于提高纤维的粘结力,从而提高重型瓦楞纸箱的抗压强度。这些添加剂包括如玉米、淀粉、胶、粘合剂和重金属,及塑料和脲(甲)醛树脂。也采用化学品喷涂纸箱外层的方法来加强纤维纸板。
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.
通常来说,用化学添加剂比交联法或其他方法费用要一些,但是当它们的使用成本大于用增加板和芯纸重量的方法,制成更坚实的纸箱时,那它们就没有意义了。
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、高压:
2、 High pressure:
高压纸板成形法也是一种在造纸过程中增强纸板强度的方法。采用扩大纸纤维上的受压点来紧密地压缩纸板。而纸板结构越紧密,强度就越大。高压纸板成形也有助于从纸浆中挤出更多的水分,但是关键是要制成更紧密的纸板,提高其抗压强度。
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、层合:
3、 Lamination:
这种增强重型瓦楞纸箱强度的方法是建立在两层或更多层;芯纸层合的基础上的。粘合剂可以是一种简单的玉米淀粉粘合剂,产生一种强度的芯纸以夹在交联的、加压成形的或常规强度的纸中间。双芯重型瓦楞纸箱保持着的单瓦楞结构,却起着重型瓦楞纸箱的作用,它比单重型瓦楞纸箱重约百分之十,但产生的抗压强度大大提高百分之十。双芯纸箱还具有更大的环压强度,同时增加了纸箱抗压强度,在托盘堆码三个以上高度时起了重要的作用。
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、交联:
4、 Crosslinking:
交联是一种在造纸过程中改变纤维方向的加工方法。通常纸纤维是纵向平行走向的,这样箱子成型后纤维水平方向围绕在箱子周围,而这是造成纸箱抵抗压力的的坏方向。交联则使许多纤维与机器方向呈90度走向,加工结果是许多纤维与箱边上下垂直走向,这样就能不增加纤维而增加了纸箱堆码强度。
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.
以上就是常见的几种提高重型瓦楞纸箱硬度的方式,一般在进行定制的时候,可以根据需要包装物品的情况来进行增加重型瓦楞纸箱硬度的方式。好了,今天的分享就到这里了,关于重型瓦楞纸箱的定制,欢迎大家咨询网站哦:重型瓦楞纸箱厂家https://www.shuangfengbaozhuang.cn!
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.
