1.受纸箱厂原纸堆放时间影响
1. Affected by the stacking time of base paper in carton factory
卷筒纸在仓库长时间堆放会造成原纸纤维疲劳,造成耐破下降。原纸如果在仓库中堆放时间超过3个月,其耐破值会下降5~8%;如果堆放时间超过6个月,耐破强度损失将达到10%以上。
The long-term stacking of web paper in the warehouse will cause the fatigue of base paper fiber and reduce the burst resistance. If the base paper is stacked in the warehouse for more than 3 months, its bursting value will decrease by 5 ~ 8%; If the stacking time exceeds 6 months, the loss of bursting strength will reach more than 10%.
2.原纸纤维
2. Base paper fiber
原纸的耐破强度主要由它本身的纤维决定。耐破度与纤维长度和纤维间的结合力有关,纤维长度增加,纤维间结合力增大,都使耐破度提高。此外,在抄造原纸的过程中适当加入一些助剂也有助于提高原纸的耐破强度。
The bursting strength of base paper is mainly determined by its own fiber. The burst resistance is related to the fiber length and the binding force between fibers. With the increase of fiber length and the binding force between fibers, the burst resistance is improved. In addition, proper addition of some additives in the process of making base paper also helps to improve the bursting strength of base paper.
3.与纸板本身的含水量有关
3. It is related to the moisture content of the paperboard itself
纸板水份含量在5%~6%时,耐破值大。水份含量8~14%范围内变化时,耐破值变化不超过5%,但水份含量达到18%时耐破值下降幅度可达10%左右。也就是说瓦楞纸箱在相对湿度为50%RH~80%RH的环境存放,其耐破强度变化幅度很小,因此可以免去试样温湿平衡处理过程,从而大大缩短测试时间。
When the moisture content of paperboard is 5% ~ 6%, the bursting value is the largest. When the moisture content changes within the range of 8 ~ 14%, the change of bursting value does not exceed 5%, but when the moisture content reaches 18%, the bursting value decreases by about 10%. In other words, when the corrugated box is stored in the environment with relative humidity of 50% RH ~ 80% RH, the change range of bursting strength is very small. Therefore, the temperature and humidity balance treatment process of the sample can be avoided, so the test time can be greatly shortened.
4.与本身材质有关
4. Related to its own material
瓦楞纸箱的耐破强度由构成纸板之内层、外层及中隔原纸本身的耐破强度决定,与瓦楞芯纸无关。
The bursting strength of corrugated box is determined by the bursting strength of the inner layer, outer layer and spacer base paper, which has nothing to do with corrugated core paper.
5.受纸箱厂储藏环境影响
5. Affected by the storage environment of carton factory
原纸或者瓦楞纸箱存贮环境以25 ± 5℃,55 ± 5%RH环境为宜。
The storage environment of base paper or corrugated box should be 25 ± 5 ℃ and 55 ± 5% RH.
以上就是瓦楞纸箱厂给大家分享关于瓦楞纸箱耐破强度的所有内容。
The above is all about the bursting strength of corrugated boxes shared by corrugated box factory.
