Abstract: The single-person drinking water sac, also known as the mobile drinking water sac, is a portable drinking water bag that military or outdoor enthusiasts love. Because it is used in harsh outdoor environments, its pressure resistance and drop resistance are especially important. This paper takes the i-Boxtek 1700 carton compression tester to test the pressure resistance performance test of individual water tanks as an example. It introduces the monitoring method, test principle and equipment parameters for detecting the pressure resistance performance of individual water tanks. Provide reference for packaging pressure resistance and selection of corresponding testing equipment. Keywords: single soldier drinking water bladder, mobile drinking water bladder, portable drinking water bag, pressure resistance performance, anti-fracture, carton compression tester 1, meaning Pressure resistance refers to the process of storage and transportation of food packaging, which inevitably occurs in stacking and squeezing, thus affecting the packaging performance of the material; stacking and crushing damage during storage, transportation, etc. through simulation packaging Such behavior, scientific quantitative analysis and judgment of the pressure resistance of the sample. The average user will fold the soldier's water bag in the backpack, and sometimes it will be used as a chair, cushion, or even a bed. Therefore, the water bag should have a certain pressure resistance performance, if the water bag has poor pressure resistance, the product It is prone to leakage or rupture, which may cause the user to replenish drinking water in time. Therefore, drinking water sac manufacturers should strengthen the pressure resistance test of drinking water sacs. Figure 1 soldier drinking water sac 2, the implementation of standards The domestic test methods for the pressure resistance of soft plastic packaging are mainly based on GB/T 10004-2008 "Plastic composite film for packaging, bag dry composite, extrusion compounding". 3, test samples A soldier's water bag provided by a company. 4, test equipment This paper uses the Labthink i-Boxtek 1700 carton compression tester to test the pressure resistance of the sample. Figure 2 i-Boxtek 1700 carton compression tester 4.1 Test methods l Crushing force test—tests the maximum force value when the test sample is crushed. l Stacking code A test - multiple times set the pressure value to be applied to the test sample. Each setting is increased based on the previous force value. After the predetermined number of times, the total deformation of the test sample is detected. l Stack code B test - set the pressure value to be applied to the test sample, and test whether the deformation amount of the test sample is qualified within the specified time. 4.2 Scope of application (1) This equipment is suitable for pressure resistance, deformation and stacking test of packaging materials such as large-capacity liquid packaging, corrugated boxes, honeycomb cartons, etc., and judges whether the pressure resistance of the carton is qualified. At the same time, it also takes into account plastic cups, plastic drums (edible oil, mineral water), paper drums, paper cans, container containers (IBC barrels), and compression tests of hollow containers. (2) This equipment meets many national and international standards, such as ASTM D642, ASTM D4169, TAPPI T804, ISO 12048, JIS Z0212, GB/T 16491, GB/T 4857.4, QB/T 1048, etc. 4.3 Equipment parameters l The test range of the device is 9 KN. l The test accuracy of the device is better than level 1, which ensures the accuracy of the test data. l The three test speeds of the device can be freely set by the user, which are 5 mm/min, 10 mm/min and 12.7 mm/min respectively. l This equipment has three test methods: maximum crushing force, stacking code A and stacking code B, which can be freely selected by users. l Intelligent design such as overload protection, limit stroke protection, and automatic fault alarm provide users with a safe operating environment. l The equipment adopts miniaturization and structural integration design to meet the testing requirements of various occasions. 5, the test process (1) Take 5 samples of individual drinking water sacs. (2) Set relevant test parameters, including pressure value, test speed, etc. (3) Place the specimen in the center of the equipment floor. (4) Click the test start option, the test starts, the equipment automatically performs the crushing force test, and the final test result is displayed. 6, test results The maximum crushing force of the single soldier drinking water bag is: 7.154 KN, 6.857 KN, 6.920 KN, 7.341 KN, 7.123 KN. 7. Conclusion The i-Boxtek 1700 carton compression tester is used to test the pressure resistance performance of the individual drinking water sac and the stacking test, which can effectively verify the pressure resistance and drop resistance of the individual drinking water sac. The precision, intelligence and test efficiency of the device are high. In addition to the pressure resistance test for individual drinking water bags, it can also be applied to the testing of various types of packaging containers such as plastic cups, plastic bowls, paper drums and cartons. .
