增加瓦楞纸箱强度的方法
The method of increasing the strength of corrugated cardboard box
在购买瓦楞纸箱的时候，都希望其强度越高越好，那么增加其强度的方法有哪些呢？今天，就带大家了解一下增加瓦楞纸箱强度的方法。
When buying corrugated boxes, we hope that the higher the strength, the better. Then what are the ways to increase its strength? Today, we will show you how to increase the strength of corrugated boxes.
1、合理制定堆码时间及堆码方式。
1. Make up the time of stacking and the way of stacking.
瓦楞纸箱的抗压强度会随堆码时间的延长而降低，在长期载荷的作用下，只要经历一段时间，瓦楞纸箱的抗压强度就会下降30%，在经历一年后，其抗压强度就只有初始值的50%，所以在设计纸箱材质时，对流通时间较长的纸箱应提高其安全系数。
The compressive strength of corrugated cartons will decrease with the lengthening of the stacking time. Under the action of long term load, the compressive strength of corrugated cartons will decrease by 30% for a period of time. After a year, the compressive strength of the corrugated cartons will only be 50% of the initial value. So when the carton material is designed, the cartons with longer circulation time should be designed. Improve the safety factor.
纸箱堆码方式也对纸箱的抗压强度产生一定影响，纸箱竖坑方向承受的压力大大超过横坑方向，所以，纸箱堆码时应保持竖坑方向受压，另外，纸箱的箱角部位承受的压力比较高，离箱角越远，承压力越低，因此纸箱在堆码时应尽量保持箱角与箱角对齐叠放。
The carton stacking method also has a certain effect on the compression strength of the carton. The pressure of the carton vertical pit direction is much more than the direction of the crater. Therefore, the carton should keep the vertical pit direction pressure when the carton is stacked. In addition, the pressure of the box corner of the carton is higher, the farther from the box angle, the lower the bearing pressure, so the carton is stacked at the time of stacking. Try to keep the box angle and the angle of the box as far as possible.
2、合理使用瓦楞纸箱的开孔方式。
2. The opening mode of corrugated cardboard box is reasonably used.
部分瓦楞纸箱上有通气孔、手挽孔等，这些开孔也会对纸箱的抗压造成重大影响。开孔越大，抗压强度减损越大，开孔离顶、底部越近，离中心往左右越远，抗压强度越低，而且开对称孔比开不对称孔的抗压强度减损要小。
There are blowholes and hand holes on some corrugated boxes. These openings also have a significant impact on the compression of cartons. The greater the opening, the greater the reduction of compressive strength, the closer the opening to the top and the bottom, the farther from the center to the left and the lower, the lower the compressive strength, and the reduction of the compression strength of the open symmetric hole is smaller than that of the open asymmetric hole.
3、合理设计纸箱的长、宽、高尺寸及比例。
3, rationally design the length, width, size and proportion of cartons.
瓦楞纸箱的抗压强度与纸箱周长、纸箱高度及纸箱长宽比存在一定的关系，纸箱周长越长，抗压强度就越高。一般来讲，纸箱长宽比在1到1.8的范围内时，对抗压强度的影响很小。纸箱长宽比为2:1时，抗压强度下降约20%，因此设计纸箱时长宽比不宜超过2，否则会造成成本浪费。
The compressive strength of corrugated boxes has a certain relationship with the carton perimeter, carton height and carton width to width ratio. The longer the carton is, the higher the compressive strength will be. Generally speaking, the carton width to width ratio is between 1 and 1.8, which has little effect on the compressive strength. When the ratio of length to width is 2:1, the compressive strength will be reduced by about 20%. Therefore, the ratio of length to width should not exceed 2, otherwise the cost will be wasted.
以上就是增加瓦楞纸箱强度的方法，而且瓦楞纸箱属于一种绿色环保产品，不仅利于环保，还利于装卸运输，其用途非常广泛。
The above is the way to increase the strength of corrugated cartons, and corrugated cartons belong to a green environmental protection product, which is not only conducive to environmental protection, but also conducive to loading and unloading transportation, its use is very wide.
