纸箱的使用相信大家应该都是知道的吧!但是这毕竟是使用纸做的产品，如果遇到了高温高压高湿的情况，它的使用寿命会不会受到影响呢?这里我们就来给大家从几个方面的内容做介绍，感兴趣的就来看看!
I believe everyone should know the use of cartons! But after all, this is a product made of paper. If it meets the situation of high temperature, high pressure and high humidity, will its service life be affected? Here we will introduce you from several aspects. Let's take a look at those who are interested!
纸箱如果做到在高温高压高湿下抗压
If the carton can withstand pressure under high temperature, high pressure and high humidity
纸箱在高温高湿环境下如何抗压?由于瓦楞纸箱纸板是由浆糊粘合而成，瓦楞纸板糊线部分的浆糊通常是固态的，但如果瓦楞纸箱长期存放在高温高湿环境中，浆糊会乳化，导致瓦楞纸板粘合位分离，导致纸箱抗压急剧下降。
How do cartons resist pressure in high temperature and humidity environment? As the corrugated board is made of paste bonding, the paste of the paste line of corrugated board is usually solid. However, if the corrugated box is stored in a high temperature and high humidity environment for a long time, the paste will be emulsified, resulting in the separation of the bonding position of corrugated board, resulting in a sharp decline in the compression resistance of the box.
为了保证出口纸箱在高温高湿条件下仍有足够的抗压能力，在客户的推动下，一些纸制品厂开始增加纸箱的高温高湿性能。纸箱高温高湿的测试方法是将纸箱密封，放入高低温交变湿热箱中，在箱顶堆放重量。重量为空箱抗压值的1/4~1/6，观察其承受重压的时间。
In order to ensure that the export cartons still have sufficient compressive capacity under high temperature and high humidity conditions, driven by customers, some paper products factories began to increase the high temperature and high humidity performance of cartons. The test method of high temperature and high humidity of carton is to seal the carton, put it into the high-temperature and low-temperature alternating damp heat box, and stack the weight on the top of the box. The weight is 1 / 4 ~ 1 / 6 of the compression value of the empty box, and observe the time when it bears heavy pressure.
为了保证纸箱在高温高湿条件下能承受一定的堆叠重量，一些纸箱厂被迫采用提高纸箱抗压强度的方法，导致纸张成本大幅增加。近两年来，在糊中加入交联剂和稳定剂，提高纸箱的耐高温高湿性得到了广泛认可。交联剂是一种聚合物聚合物。添加糊后，其分子将取代淀粉分子中的羟基，形成稳定的交联。
In order to ensure that cartons can bear a certain stacking weight under the conditions of high temperature and humidity, some carton factories are forced to adopt the method of improving the compressive strength of cartons, resulting in a significant increase in the cost of paper. In the past two years, it has been widely recognized to add crosslinking agent and stabilizer to the paste to improve the high temperature and high humidity resistance of cartons. Crosslinking agent is a kind of polymer. After adding paste, its molecules will replace the hydroxyl groups in starch molecules to form a stable cross-linking.
由于交联剂分子的反应过程相对缓慢，过程不可逆转，纸板离开生产线后粘结防潮效果逐渐增强，完全疏水，形成坚固防潮的浆膜，使纸板具有良好的耐高温高湿性能。
As the reaction process of crosslinking agent molecules is relatively slow and irreversible, the bonding moisture-proof effect of paperboard is gradually enhanced after leaving the production line, completely hydrophobic, forming a solid moisture-proof slurry film, so that the paperboard has good high temperature and high humidity resistance.
此外，淀粉分子被交联剂分子包围，增强了耐热性和抗剪切性，从而在循环过程中保持粘度的稳定性。由于淀粉分子中的羟基被取代，从亲水性到疏水性，干燥时容易脱水，提高干燥速度，进而提高速度。交联剂分子容易亲和纤维分子，也有助于提高粘结强度。
In addition, starch molecules are surrounded by crosslinker molecules, which enhances heat resistance and shear resistance, so as to maintain the stability of viscosity during circulation. Due to the substitution of hydroxyl groups in starch molecules, from hydrophilicity to hydrophobicity, it is easy to dehydrate during drying, improve the drying speed, and then improve the drying speed. Crosslinking agent molecules are easy to affinity with fiber molecules, which also helps to improve the bonding strength.
