瓦楞紙箱的設計不僅可以防止包裝被水弄濕，還可以防止盒子本身被水弄濕。為了防潮，通常可以用防水劑解決。所以根據防水劑的作用，防潮紙箱的制作方法可以分為：臨時防水處理和長期防水處理。
The design of corrugated box can not only prevent the package from being wet by water, but also prevent the box itself from being wet by water. In order to prevent moisture, usually can be solved with waterproof agent. Therefore, according to the role of waterproof agent, the production method of moisture-proof carton can be divided into: temporary waterproof treatment and long-term waterproof treatment.
臨時防水劑：瓦楞紙板在生產過程中經過臨時防水劑處理后，具有臨時防水功能。當水在短時間內落在上面時，它不會弄濕，而是變成水滴，從而防止水滲透到紙板中。
Temporary waterproof agent: corrugated board has temporary waterproof function after being treated with temporary waterproof agent in the production process. When water falls on it in a short period of time, it will not get wet, but become water droplets, thus preventing water from penetrating into the cardboard.
涂層在早期用于織物纖維，然后用于紙板加工。所以瓦楞紙箱工廠大多用脫水劑這個名字。水萃取劑為蠟乳液，固含量通常為48%-51%。其特征在于使用時可用30倍左右的水稀釋，然后涂在成型的瓦楞紙箱表面。在150℃左右的溫度下干燥后，紙張表面的纖維由于被醋包裹而具有較低的表面張力，從而形成了不被水潤濕的表層。
Coatings were used in the early days for fabric fibers and then for paperboard processing. So most corrugated box factories use the name of dehydrating agent. The water extractant is wax emulsion, and its solid content is usually 48%-51%. The utility model is characterized in that it can be diluted with about 30 times water when in use, and then coated on the surface of the formed corrugated box. After drying at about 150 ℃, the fiber on the surface of the paper has a lower surface tension because it is wrapped by vinegar, thus forming a surface layer that is not wetted by water.
當它接觸到水時，水不會在紙板上打濕，水滴會滾下來，從而實現防水。但蠟對紙纖維的附著力不好，尤其是水提液稀釋30倍時，固含量只有1.5，只有很薄的一層紙表面纖維被蠟包裹。此外，由于蠟乳液中蠟的粒徑通常比普通聚合物乳液大，很難滲透到紙纖維的深度，水萃取劑通常對一種水敏感。化學品，紙張表面通常很快。大米的破乳和沉淀，所以水萃取劑中的大多數蠟顆粒只存在于一層非常薄的紙上。
When it comes into contact with water, the water won't get wet on the paperboard, and the water drops will roll down to make it waterproof. But the adhesion of wax to paper fiber is not good, especially when the water extract is diluted 30 times, the solid content is only 1.5, only a very thin layer of paper surface fiber is wrapped by wax. In addition, because wax particles in wax emulsion are usually larger than ordinary polymer emulsions, it is difficult to penetrate into the depth of paper fibers. Water extractant is usually sensitive to a water. Chemicals, paper surfaces are usually fast. Because of the demulsification and precipitation of rice, most of the wax particles in the water extractant only exist on a very thin layer of paper.
瓦楞紙箱在外摩擦的作用下，蠟很容易被擦掉，露出無蠟纖維，從而大大降低了防水效果。為了增強蠟對紙纖維的粘附性，水提取物中經常存在松香衍生物或羧基化聚合物乳液，它們對紙纖維具有良好的粘附性，并且與蠟具有良好的相容性。因此，它們的加入促進了蠟對紙纖維的粘附，如果蠟被改性，例如通過氧化和結構化，它具有類似的作用，并且蠟對紙纖維的粘附可以增加。
Corrugated box in the role of external friction, wax is easy to be wiped off, exposing non wax fiber, thus greatly reducing the waterproof effect. In order to enhance the adhesion of wax to paper fibers, rosin derivatives or carboxylated polymer emulsions are often found in aqueous extracts, which have good adhesion to paper fibers and have good compatibility with wax. Therefore, their addition promotes the adhesion of wax to paper fibers. If wax is modified, such as by oxidation and structure, it has a similar effect, and the adhesion of wax to paper fibers can be increased.
但是小編還是需要提醒大家，除了這些措施，疏水劑在這個濃度下還是不是防水膜層，所以面對摩擦，比如加工過程中的紙箱，堆疊過程中的摩擦，防水面往往是沒有用的。這就是為什么涂有防水劑的瓦楞紙箱被指定為臨時防水劑的原因。目前，防水劑已在一些紙箱工廠廣泛使用，并已成為基本工藝。
However, Xiaobian still needs to remind you that in addition to these measures, hydrophobic agent is not waterproof film at this concentration, so it is often useless to face friction, such as carton in processing, friction in stacking process and waterproof surface. This is why corrugated boxes coated with waterproofing agent are designated as temporary waterproofing agent. At present, waterproof agent has been widely used in some carton factories, and has become the basic technology.
The most important thing to buy products is quality, and choosing merchants is honesty. Corrugated box manufacturers sincerely provide excellent services for customers. Welcome to our website: http://www.ywjbs.com Below message consultation
