Paper cup body stiffness test analysis program
A paper cup is a paper container which is obtained by machining and bonding a base paper (white paperboard) made of chemical wood pulp, and has a cup shape. Paper cups for frozen foods can be coated with ice cream, jam and butter. According to the use, it can be divided into three types of paper cups: cold drink cup, hot drink cup and ice cream cup. Paper cups are closely related to people's diet, so the quality of paper cups has become a topic of concern. At present, our country has requested that the production management of paper cups be upgraded to the food level. Therefore, all manufacturers of paper cups sold in the market must have QS quality and safety production licenses, and their license numbers can be checked on the website of the State Bureau of Quality and Safety Supervision. does it exist.
Paper cup stiffness refers to the performance of the paper cup body when it is subjected to external force. When the paper cup is lower than the normal stiffness value, it will be severely deformed when it is not strong, and it will not end up, which will affect the use. The cup body stiffness value is better. If the wall of the cup is too thick, it will increase the production cost. Therefore, detecting the stiffness of the paper cup is one of the important indicators to measure the quality of the product. In 2012, the national standard â€œGB/T27590-2011 Paper Cupâ€ promulgated by the General Administration of Quality Supervision, Inspection and Quarantine clearly stated the paper cup stiffness test data and test methods. The paper cups are divided into superior products, first-class products and qualified products according to the stiffness of the paper cup. The reference data is as follows:
The paper cup stiffness test method is as follows:
1. Place the sample cup on the movable gantry of the cup stiffness tester, adjust the movable gantry so that the measuring end of the pressure gauge and the end of the ratchet device are close to the side wall of the cup, and the vertical distance between the side head and the bottom of the cup is about It is two-thirds of the height of the cup and the seam of the cup of the paper cup to be tested is facing the tester.
2. Adjust the position of the pressure gauge so that the pressure gauge head just touches the side wall of the cup vertically, adjust the zero point of the pressure gauge, and then tighten the set screw.
3. Turn the ratchet handle to move the tip forward (9.5 Â± 0.5) mm for about 1 s, then return the handle and record the maximum indication on the dynamometer as the stiffness of the cup.
After the test, the quality level of the paper cup is divided according to the data of the cup stiffness. Jinan Sanquan Zhongshi Experimental Instrument Co., Ltd. specializes in the research and development of paper cup body stiffness measuring instrument for paper cup enterprises. The equipment adopts automatic electronic test, large liquid crystal microcomputer control system, and equipment is equipped with micro printer. It can print test data at any time. With a double-headed structure, the test is more stable and the data is more accurate. Not only for small paper cups, but also for some instant noodle barrels, small and medium-sized popcorn buckets. Through the inspection of professional equipment, the quality of paper cups is improved, and at the same time it helps people's quality of life improve.
