瓦楞紙箱的抗壓強(qiáng)度是指瓦楞紙箱在壓力試驗(yàn)機(jī)均勻施加的動(dòng)壓作用下，對(duì)瓦楞紙箱損傷的載荷和變形。
The compressive strength of corrugated box refers to the load and deformation of corrugated box damaged by the dynamic pressure uniformly applied by the pressure testing machine.
瓦楞紙箱抗壓測(cè)試的過(guò)程：
Process of corrugated box compression test:
1、預(yù)加負(fù)荷發(fā)展階段，確保一個(gè)紙箱與抗壓機(jī)壓板進(jìn)行接觸；
1. In the preloading development stage, ensure that a carton is in contact with the pressing plate of the compression machine;
2、橫向壓縮線下壓時(shí)，載荷略有增加，變形變化較大；
2. When the transverse compression line is pressed down, the load increases slightly and the deformation changes greatly;
3、紙箱側(cè)壁受壓分析階段，此時(shí)系統(tǒng)負(fù)荷增加，變形量增加一個(gè)緩慢；
3. In the compression analysis stage of the side wall of the carton, the system load increases and the deformation increases slowly;
4、紙箱被完全可以破壞時(shí)，此時(shí)為紙箱的壓潰點(diǎn)。
4. When the carton can be completely damaged, this is the crushing point of the carton.
