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!

紙箱如果做到在高溫高壓高濕下抗壓

If the carton can withstand pressure under high temperature, high pressure and high humidity

紙箱在高溫高濕環(huán)境下如何抗壓?由于瓦楞紙箱紙板是由漿糊粘合而成，瓦楞紙板糊線部分的漿糊通常是固態(tài)的，但如果瓦楞紙箱長期存放在高溫高濕環(huán)境中，漿糊會乳化，導致瓦楞紙板粘合位分離，導致紙箱抗壓急劇下降。

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.

為了保證出口紙箱在高溫高濕條件下仍有足夠的抗壓能力，在客戶的推動下，一些紙制品廠開始增加紙箱的高溫高濕性能。紙箱高溫高濕的測試方法是將紙箱密封，放入高低溫交變濕熱箱中，在箱頂堆放重量。重量為空箱抗壓值的1/4~1/6，觀察其承受重壓的時間。

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.

為了保證紙箱在高溫高濕條件下能承受一定的堆疊重量，一些紙箱廠被迫采用提高紙箱抗壓強度的方法，導致紙張成本大幅增加。近兩年來，在糊中加入交聯(lián)劑和穩(wěn)定劑，提高紙箱的耐高溫高濕性得到了廣泛認可。交聯(lián)劑是一種聚合物聚合物。添加糊后，其分子將取代淀粉分子中的羥基，形成穩(wěn)定的交聯(lián)。

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.

由于交聯(lián)劑分子的反應過程相對緩慢，過程不可逆轉(zhuǎn)，紙板離開生產(chǎn)線后粘結(jié)防潮效果逐漸增強，完全疏水，形成堅固防潮的漿膜，使紙板具有良好的耐高溫高濕性能。

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，淀粉分子被交聯(lián)劑分子包圍，增強了耐熱性和抗剪切性，從而在循環(huán)過程中保持粘度的穩(wěn)定性。由于淀粉分子中的羥基被取代，從親水性到疏水性，干燥時容易脫水，提高干燥速度，進而提高速度。交聯(lián)劑分子容易親和纖維分子，也有助于提高粘結(jié)強度。

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.
