包装箱含水率过高的影响有哪些?

我们的产品在运输过程中需要用到包装箱包装来保护,那我们在购买包装箱时板材含水率也是一个需要注意的细节,包装行业协会对于包装箱的含水率有硬性规定的,用于出口的海运包装箱含水率≤18%,既然有硬性规定,那就意味着一定对包装箱品质有影响,今天我们就来分析一下包装箱含水率过高的影响都有哪些。

Our products need to be packed in packing boxes for protection during transportation. When we buy packing boxes, the moisture content of plates is also a detail that needs attention. The packaging industry association has rigid regulations on the moisture content of packing boxes. The moisture content of shipping packing boxes used for export is ≤ 18%. Since there are rigid regulations, it means that it must have an impact on the quality of packing boxes Let's analyze the influence of high moisture content in the packing box.

1、造成包装箱加工难度大且误差加大:用来加工包装箱的木材的含水率过高或者干燥不均匀,在后期的加工中机械加工处理的难度会加大,含水率过高的木材在平刨上特别不容易操作,同时误差也会加大,因为木材有“干缩湿胀”的特性。

1. The difficulty and error of packing box processing are increased: the moisture content of the wood used to process packing box is too high or uneven drying, and the difficulty of mechanical processing will increase in the later processing. The wood with too high moisture content is particularly difficult to operate in planing, and the error will also increase, because the wood has the characteristics of "drying shrinkage and swelling".

2、包装箱会发生变形:由于含水率太高,木材收缩剧烈,这种收缩变化程度超出日常普通收缩,包装箱因此而翘曲变形,因为现在的含水率高,等加工完之后,木材的含水率降低至本地区的平衡含水率的时候,木材就会发生变形、翘曲等严重的质量问题。

2. Packaging box will be deformed: because the moisture content is too high, the wood shrinks violently, which is beyond the ordinary shrinkage, and the packaging box will be warped. Because the moisture content is high now, when the moisture content of wood is reduced to the balanced moisture content of the region after processing, serious quality problems such as deformation and warpage will occur.

3、包装箱会有霉变现象产生:当木材干燥不良,或者木材中的水分挥发慢,容易出现发霉现象。特别是天气湿度大、温度低,木材内外的水分均难散尽,会造成包装箱的发霉,如果遇到梅雨季节,实木包装箱如何防止蓝变也是一门学问,需要我们去做相关的防护工作。

3. Packaging box will have mildew phenomenon: when the wood is not dry, or the moisture in the wood volatilizes slowly, it is easy to appear mildew phenomenon. Especially in the high humidity and low temperature, the moisture inside and outside the wood is difficult to disperse, which will cause the mildew of the packing box. In the rainy season, how to prevent the blue change of the solid wood packing box is also a knowledge, and we need to do the relevant protection work.

4、造成包装箱腐变:由于水分高容易造成腐朽菌、霉菌与变色菌的滋生,加速包装箱腐朽变质与损坏。

4. Cause box decay: due to the high moisture content, it is easy to cause the breeding of decaying bacteria, mold and color changing bacteria, and accelerate the deterioration and damage of the box.

我国把板材中所含水分的质量与绝干后板材质量的百分比,定义为板材含水率,当木材干燥不当,含水率未达到与当地环境相适应的平衡点时就用来加工包装箱,一般会造成发霉,甚至因木材胀缩程度大引起包装箱开裂、变形等。

In our country, the percentage of the moisture content in the board and the dry board is defined as the moisture content of the board. When the wood is not dried properly and the moisture content does not reach the balance point suitable for the local environment, it is used to process the packing box. Generally, it will cause mildew, and even cause cracking and deformation of the packing box due to the large degree of wood expansion and shrinkage.
