紙板箱是一種現(xiàn)實中很常見的包裝方式，它的規(guī)格沒有限制，可以根據(jù)包裝物品進行臨時折疊，確定大小完全，而且較，同時還具有回收再利用的環(huán)保特性，因此受到很多行業(yè)的歡迎。但是作為紙箱，怕水怕火是難以避免的問題，明火接觸紙箱的可能性很小，但是水是很常見的，下面小編就為大家介紹一下紙板箱是怎么防水的。
Cardboard box is a very common way of packaging in reality, its specifications are not limited, it can be temporarily folded according to the packaging items to determine the size, and the price is low, at the same time, it also has the environmental protection characteristics of recycling, so it is welcomed by many industries. But as a carton, fear of water and fire is an unavoidable problem. The possibility of open fire contacting the carton is very small, but water is very common. The following editor will introduce how the carton is waterproof.
紙板板在生產(chǎn)過程中采用暫時性防水劑處理后，具有暫時防水功能。當水短時間落于其上時，不沾濕而成水滴，能防止水浸透紙板。暫時性防水劑處理紙板工藝近十年來在我國各大紙箱廠均已應用。這種防水劑當初從日本引進，其日文字面為“拔水劑”。
The paperboard has the function of temporary waterproof after being treated with temporary waterproof agent in the production process. When the water falls on it for a short time, it will not get wet and become water drops, which can prevent the water from soaking the paperboard. In recent ten years, the technology of temporary waterproof agent treating paperboard has been applied in all major carton factories in China. This kind of waterproof agent was introduced from Japan at the beginning, and its Japanese literal is "water extracting agent".
這種涂料早期用于織物纖維上，后來才用于紙板的處理。因此大多樹紙箱廠就采用拔水劑的叫法。拔水劑是一種蠟乳液，固體含量一般為：48%～51%，它的特點是在使用時可用30倍左右的水稀釋，然后涂布于正在成型的紙板面上，經(jīng)過150℃左右的溫度干燥，紙表面纖維由于醋的包裹，而具有表面張力，
This kind of coating was used on the fabric fibers in the early stage, and then used in the treatment of paperboard. Therefore, most of the tree carton factory uses the name of water extraction agent. Water extraction agent is a wax emulsion, solid content is generally 48% to 51%, it is characterized by the use of 30 times the water can be diluted, and then coated on the forming of the cardboard surface, after 150 degrees Celsius drying temperature, paper surface fiber wrapped by vinegar, and has low surface tension.
形成對水不浸潤的面層。當遇水時，水在這個紙板上不浸潤，形成水滴滾落，從而達到防水的作用。但是，蠟對紙纖維的附著力并不好，特別是當拔水劑被稀釋了。
Form a surface that is not wetted by water. When meeting water, water does not infiltrate on this paperboard, forming water drops to roll down, so as to achieve the function of waterproof. However, the adhesion of wax to paper fiber is not good, especially when the extractant is diluted.
30倍以后，其固含量較，紙表面纖維只有很薄一層被蠟包裹。另外由于蠟乳液中蠟的粒徑一般都比通常的高分子乳液粒徑大，要往紙纖維深處滲透也難，同時拔水劑一般對明礬一類化學品敏感，在紙表面往往很快破乳而沉淀下米，因此拔水劑中的蠟粒子絕大部分只在紙面上很薄的一層存在。
After 30 times, its solid content is low, and only a thin layer of fiber on the paper surface is wrapped by wax. In addition, because wax particles in wax emulsion are generally larger than the size of ordinary polymer emulsion, it is difficult to infiltrate into the depths of paper fibers. At the same time, the water absorbent is generally sensitive to alum chemicals, and it often breaks down quickly on the surface of paper.
在有外摩擦力的作用下，蠟容易被摩擦掉，露出無蠟包裹的纖維，防水效果大大降。為了增強蠟對紙纖維的附著力，在拔水劑中往往有松香衍生物或羧化高分子乳液，它們既對紙纖維有很好的粘附力，與蠟又有較好的相溶性。這樣，它們的加入可促進蠟在紙纖維上的附著性，同時如果對蠟進行改性，如將其氧化、基化，也有類似作用，都可以使蠟對紙纖維的附著力增加。但是必須指出的是，就是增加了這些措施，拔水劑在這樣的濃度下所形成的仍不是一個防水膜層，因此在遇到摩擦，
Under the action of external friction, the wax is easy to be rubbed off, exposing the fiber wrapped without wax, and the waterproof effect is greatly reduced. In order to enhance the adhesion of wax to paper fibers, there are often rosin derivatives or carboxylated polymer emulsions in the water extraction agent. They have good adhesion to paper fibers and good solubility with wax. In this way, their addition can promote the adhesion of wax on paper fiber. At the same time, if wax is modified, such as oxidation and basification, it also has a similar effect, which can increase the adhesion of wax on paper fiber. However, it must be pointed out that even with the increase of these measures, the waterproof film formed by the extractant at such concentration is still not a waterproof film, so when encountering friction,
如紙箱在搬運、堆碼過程中遇摩擦，往往會使這一防水表面失去作用。這就是為什么把涂布拔水劑的這類紙箱定為暫時性防水紙箱。目前，拔水劑在一些紙箱廠已是廣泛使用，并成為一道基本工序。
If cartons encounter friction in the process of handling and stacking, the waterproof surface will lose its function. This is why the coating of such cartons as temporary waterproof cartons. At present, water extractant has been widely used in some carton factories and has become a basic process.
The above is the introduction of the waterproof function of the cardboard box. It should be noted that this is only a temporary waterproof means. In the normal use of the cardboard box, we should pay attention to avoid the problems of rain and moisture. For more information, please click: carton manufacturer http://flyconn.cn .
