Testing the initial adhesion of the ring by the manufacturer of online purchasing health promoting tape

Source: Sanquan Zhongshi headquarters editor: Sanquan Zhongshi news department August 24, 2017 Abstract: online shopping promoting the production of adhesive tape manufacturers to test the ring initial adhesion Lt-3000, designed and developed by Jinan Sanquan Zhongshi Experimental Instrument Co., Ltd., is suitable for the initial adhesion of various kinds of adhesive tapes, adhesives and other products The instrument meets the international standards such as final, ASTM and GB / t31125-2014 It is suitable for research institutions, adhesive import and export enterprises, inspection and quarantine institutions to test the initial viscosity of various products Key words: annular initial viscosity tester, adhesive tape annular initial viscosity tester, annular initial viscosity tester, automatic annular initial viscosity tester, annular initial viscosity tester, annular initial viscosity tester With the development of taobao.com, various network sales platforms are springing up At the same time, logistics industry and packaging industry have become a rapid development industry And tape also plays an important role in it Tape quality is also the concern of major e-commerce, and initial adhesion is an important physical index to determine the tape The initial viscosity can be divided into the inclined rolling ball method and the ring method Today we will focus on the detection method of the ring initial viscosity Lt-3000, designed and developed by Jinan Sanquan Zhongshi Experimental Instrument Co., Ltd., is specially designed for the test of the ring initial viscosity performance of adhesive products Online shopping promotion tape manufacturers to detect the ring initial adhesive force, what is the ring initial adhesive force? The ring initial adhesive force refers to the separation force after contacting the ring adhesive tape material (adhesive surface outward) with a certain area of standard test plate at a certain speed Test principle of ring initial adhesion tester lt-3000: contact the ring adhesive tape with the test plate of the specified area under its own weight, and measure the pull force of the adhesive tape from the test plate The specific test steps of using the annular initial viscosity tester lt-3000 to detect the annular initial viscosity are as follows: 1 Keep the automatic annular initial viscosity tester horizontal, turn on the power supply, release the locking rod; 2 Turn on the power switch; 3 Confirm that the upper retainer is at the top of Zui; 4 Loosen the fixing screw, and then remove the stainless steel test plate 5 Put the cleaned stainless steel test plate back into the test fixture and tighten the fixing screws 6 Remove the release paper covering the sample 7 Turn the sample completely and be careful not to make it wrinkle Complete a teardrop like ring with the circumference of 98mm and the adhesive surface facing out ——Ring initial viscosity tester 8 Fasten the two ends of the sample ring together with 13 mm wide covering adhesive tape 9 Insert the sample ring into the upper retainer to ensure that the sample ring is in a proper position to form the upper assembly 10 Zero the instrument 11 Chang'an "electric" button, the upper assembly starts to move downward The upper assembly stops automatically after completing a complete cycle At this point, the dynamometer returns to its original position 12 A complete cycle begins with the upper assembly moving down, and the test ring contacts the test plate to form a bond Then, the assembly moves upward at a speed of 300 mm / min ± 10 mm / min, and the dynamometer records the tensile force required for the specimen to pull the ring away from the test plate At the end of a cycle, the upper component will return to its original position 13 Record the large tensile force required for the specimen ring to separate from the stainless steel test plate and the failure mode of the bond between the specimen ring and the test plate 14 There are three kinds of bond failure modes: interface failure, cohesive failure and transfer failure 15 After the test, clean the stainless steel test plate in the test fixture with reagent, and cover the stainless steel test plate with dust-free cloth to prevent the surface from being scratched Summary: online shopping has become a convenient way for people to shop in Zui The paper also mentions that tape plays an important role in packaging The detection of the ring initial adhesive force of tape has attracted the attention of major adhesive tape manufacturers According to the steps given to you by Xiaobian, using the annular initial viscosity tester lt-3000 designed and developed by Jinan Sanquan Zhongshi Experimental Instrument Co., Ltd can help the manufacturer easily solve the initial viscosity test of the tape ——Manufacturer of ring initial viscosity tester
