影响纸箱包装抗压强度的要素

来源:https://www.gtmfpack.com 发布时间:2022-06-16

包装抗压强度是指在压力试验机上均匀施加动态压力后,到箱体破裂为止的载荷和变形量。纸箱的整体性能直接体现在这里就为大家做一个简单的纸箱包装抗压强度介绍。
Packaging compressive strength refers to the load and deformation until the box is broken after the dynamic pressure is uniformly applied on the pressure testing machine. The overall performance of cartons is directly reflected here. Here is a simple introduction to the compressive strength of carton packaging.
纸箱体的抗压强度受到以下因素的影响:
The compressive strength of the carton body is affected by the following factors:
1.纸箱包装是用各种纸组成的,合理搭配是保证纸箱抗压强度的基本条件。
1. carton packaging is composed of various papers. Reasonable matching is the basic condition to ensure the compressive strength of cartons.
测试过每一层纸的物理性能后,我们就可以开始计算纸箱的抗压强度,然后在生产过程中的每一道工序进行抗压强度的计算,来控制纸箱的抗压强度。
After testing the physical properties of each layer of paper, we can start to calculate the compressive strength of the carton, and then calculate the compressive strength of each process in the production process to control the compressive strength of the carton.
2.纸张的环压强度对保证纸箱抗压强度关重要,但纸张的其它物理性能也不可忽略。
2. the annular compressive strength of the paper is very important to ensure the compressive strength of the carton, but other physical properties of the paper can not be ignored.
纸,尤其是楞纸的抗张强度不能满足时,纸箱包装在抗压测验中会呈现力值与变形量一向平稳递加,而有效能值较低,纸箱包装在抗压测验中会呈现力值与变形量一向稳定递加。纸的防水性能也很重要,尤其是箱体对纸的防水性能要求较高,有时虽然纸箱的抗压强度很高,但由于纸张不防水,纸箱放在冷库中会吸潮,形成塌库。
When the tensile strength of paper, especially corrugated paper, cannot be satisfied, the force value and deformation of carton packaging will always increase steadily in the compression test, while the effective energy value is low. The force value and deformation of carton packaging will always increase steadily in the compression test. The waterproof performance of paper is also very important. In particular, the box has high requirements for the waterproof performance of paper. Sometimes, although the compressive strength of the carton is very high, because the paper is not waterproof, the carton will absorb moisture in the cold storage and form a collapse.
3.包装纸箱生产过程还对抗压强度形成影响。
3. the production process of packaging carton also has an impact on the compressive strength.
经试验,在相同条件下,纸箱每加宽1mm,纸箱抗压强度下降90N~130N,变形量约为2mm.压线过宽,纸箱包装将形成每加宽1mm的纸箱包装,并使其变形量变大,有效能值小,变形量大。为了保证抗压强度,我们应努力提高生产工艺,降低各工序对纸箱抗压强度的影响。
According to the test, under the same conditions, the compressive strength of the carton decreases by 90n~130n and the deformation is about 2mm for every 1mm of carton width If the pressing line is too wide, the carton packaging will form a carton packaging with each widening of 1mm, and make its deformation larger, with small effective energy value and large deformation. In order to ensure the compressive strength, we should strive to improve the production process and reduce the impact of various processes on the compressive strength of cartons.
4.根据纸箱箱型选择合适的楞型也是非常重要的。
4. it is also very important to select the appropriate ridge type according to the carton type.
一般认为楞型越大,纸箱压缩强度就越高,容易忽略楞型对变形量的影响。拉坯形状越大,纸箱压缩强度越大,变形量越大;楞型越小,纸箱压缩强度越小,变形越小。如果纸箱太大,楞形却很小,纸箱在测压抗压测试时很容易被压垮;纸箱太小,纸板形状却很大,抗压测验时会形成变形量过大,缓冲过程长,有效能值与纸箱的抗压性差。
It is generally believed that the larger the ridge, the higher the compression strength of the carton, and it is easy to ignore the influence of the ridge on the deformation. The larger the blank shape, the greater the compression strength and deformation of the carton; The smaller the ridge, the smaller the compression strength of the carton and the smaller the deformation. If the carton is too large and the ridge shape is very small, the carton is easy to collapse during the pressure and compression test; The carton is too small, but the shape of the cardboard is very large. During the compression test, the deformation will be too large, the cushioning process will be long, and the effective energy value is poor with the compression resistance of the carton.
5.水分对纸箱抗压强度的影响更不容忽视。
5. the influence of moisture on the compressive strength of cartons should not be ignored.
箱体的生产环境、寄存环境、使用环境、气候、气候等因素对纸箱含水率产生影响,为了保证纸箱抗压强度,应尽量避免外界环境对纸箱含水率的影响。
The production environment, storage environment, use environment, climate, climate and other factors of the box have an impact on the moisture content of the box. In order to ensure the compressive strength of the box, try to avoid the impact of the external environment on the moisture content of the box.
