The factors affecting the compressive strength of Fuyong carton packaging: the compressive strength of the corrugated carton of the Shenzhen Guangtong Canton Paper Co., Ltd. packing the Shenzhen carton factory is the large load and deformation of the box under the pressure test machine.
First亚博取现到账超快、The compression testing process of carton packaging in Fuyong can be divided into four stages：
1亚博取现到账超快、Preloading stage to ensure carton contact with compression plate;
2亚博取现到账超快、The horizontal line is under pressure, the engine load increases, and the deformation changes greatly;
3亚博取现到账超快、In the side wall compression stage, the load increases rapidly and the deformation increases slowly;
4亚博取现到账超快亚博取现到账超快亚博取现到账超快、When the carton is completely damaged, it is the extrusion point of the carton at this time.
Second亚博取现到账超快亚博取现到账超快亚博取现到账超快、 The main factors affecting the compressive strength of Fuyong cartons are as follows：
1、The production process of cartons will also affect the compressive strength.
The test results showed that under the same conditions, the horizontal line width of the carton was widened every 1mm, and the compression strength of the carton decreased by 90N to 130n, and the deformation increased by about 2mm. The line is too wide, so that the carton will increase slowly in the compression test, the effective value is very small, and the final deformation. In order to ensure compressive strength, the production process should be improved as far as possible, so as to reduce the influence of each procedure on the compressive strength of cartons.
2亚博取现到账超快、The carton is made of various kinds of paper. The reasonable matching of paper is the basic condition to ensure the carton's compressive strength.
By testing the physical properties of each layer of paper, the initial compressive strength of the box can be calculated, and then the control process of the cartons, such as the compressive strength and the compressive strength, is calculated.
3亚博取现到账超快、The compressive strength of carton can not be ignored.
The production environment, storage environment, environment, weather, climate and other factors will affect the water content of carton box, in order to ensure the compressive strength of the carton, we should try to avoid the effect of external environment on the water content of carton.
4亚博取现到账超快、The strength of paper ring is the key to ensure the compressive strength of carton, but other physical properties of paper can not be ignored.
In particular, the tensile strength of corrugated cardboard is not enough. In the compression test, the stress and deformation of the carton will increase, the final value is very high, the effective value is very low, such as the test after the accordion deformation. Waterproof paper is also very important, especially the waterproof performance of the refrigerator is more demanding for paper, although the compression strength of cartons is high, but because the carton is not waterproof, cold storage is easy to absorb water, resulting in the collapse of the library.
5亚博取现到账超快、According to the types of cartons in Fuyong, Shenzhen, it is also crucial to choose the right shape.
In people's minds, the larger the shape of the carton is, the higher the compressive strength of the carton is. It is easy to ignore the effect of deformation on the deformation. The larger the corrugated cardboard, the greater the compressive strength of the carton and the greater the deformation. The smaller the pin shape, the smaller the compressive strength of the carton and the smaller the deformation. If the carton is too large, the corrugated carton is very small, the compression test is easily broken; the corrugated cardboard box is too small, but the large compression test will cause excessive deformation, the long buffer process, the large deviation of the effective value and the limit force value.
