纸箱厂家是如何增强纸箱硬度的?

来源:http://www.liufangshun.com/ 时间:2021-01-29 发布人:admin

在如今很多行业都需要使用纸箱,但是他们对于纸箱的硬度还是不满意,如果是硬度不好的纸箱装盛比较的物品就会很容易出现变形或者严重损坏。纸箱厂家为了增强纸箱的硬度进行了相关的研究,下面是一些增强纸箱硬度的方法。

In today's many industries need to use cartons, but they are still not satisfied with the hardness of the cartons. If the hardness is not good, the cartons will be easily deformed or seriously damaged. Carton manufacturers in order to enhance the hardness of the carton related research, the following are some methods to enhance the hardness of the carton.

1、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。有时,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 carton. These additives include corn, starch, gum, adhesives and heavy metals, as well as plastics and urea formaldehyde resins. Sometimes, chemicals are used to spray the outer layer of the carton to strengthen the fiberboard.

一般来说,用化学添加剂比交联法或其他方法费用要低一些,但是当它们的使用成本大于用增加底板和芯纸重量的方法,制成更坚实的纸箱时,那么它们都没有意义了。

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 more solid cartons by increasing the weight of the bottom plate and core paper, they are meaningless.

2、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.

3、交联

3. Cross linking

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,这种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 fiber is parallel to the longitudinal direction. After the box is formed, the horizontal direction of the fiber surrounds the box, which is the bad direction that causes the box to resist the 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.

测量一块衬纸在交联时的强度就是测出它承受环压破坏的能力。把一个半英寸宽6英寸长的纸板条变成圆环,用以受压,破坏它所需用的磅数就是该材料的环压强度。高环压强度的衬纸加上高环压强度的芯纸,不仅增加丁纸箱垂直边的抗压能力,而且增加了整个纸箱的抗压强度。

To measure the strength of a piece of interlining paper during crosslinking is to measure its ability to withstand ring pressure damage. A half inch wide and six inch long cardboard strip is turned into a ring to be compressed. The number of pounds needed to destroy it is the ring compression strength of the material. The liner paper with high ring crush strength and the core paper with high ring crush strength not only increase the compressive strength of the vertical side of the carton, but also increase the compressive strength of the whole carton.

4、层合

4. Lamination

这种增强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。

This method of strengthening carton strength is based on the lamination of two or more layers of core paper. 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.
