Abstract: The online shopping promotion tape manufacturer detects the initial tack of the ring. The ring-shaped initial tack tester LT-3000 designed and developed by Jinan Sanquan Zhongshi Experimental Instrument Co., Ltd. is suitable for the initial adhesion of various adhesives and adhesives. The instrument meets international standards such as FINAT, ASTM and GB/T31125-2014 national standards, and is suitable for testing institutions, adhesive import and export enterprises, inspection and quarantine institutions, etc. to detect the initial viscosity of various products.
Key words: ring initial tack tester, adhesive tape ring initial tack machine, ring initial tack tester, automatic ring initial tack machine, ring type initial tack tester, ring method initial tack tester
With the development of Taobao.com, major online sales platforms have sprung up. At the same time, the logistics industry and the packaging industry have become a fast-growing industry. The tape also plays an important role in it. The quality of the tape is also a concern of major e-commerce companies. Initial tack is an important physical indicator for determining tape. The initial viscosity is divided into the bevel ball method and the ring method. Today we focus on the detection method of the ring initial adhesion.
Jinan Sanquan Zhongshi Experimental Instrument Co., Ltd. designed and developed the ring initial tack tester LT-3000 designed for the ring initial tack performance test of adhesive products. Online shopping promotion tape manufacturers to detect the initial tack of the ring, what is the initial tack of the ring? The ring initial tack force refers to the separation force after contacting the endless adhesive tape material (the rubber faces outward) with a standard test plate of a certain area at a certain speed.

Ring Initial Viscosity Tester LT-3000 Test principle: The annular adhesive tape is contacted with the test plate of the specified area under the action of its own weight, and the force of the adhesive tape pulled away from the test plate is measured.
The specific test procedure for detecting the initial tack of the ring using the ring initial tack tester LT-3000 is as follows:
1. Keep the automatic ring initial visco performance tester horizontally, turn on the power, release the lock lever 2. Turn on the power switch 3. Confirm the upper gripper at the top position of the zui 4. Loosen the set 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 set screw. 6. Remove the release paper covering the sample. 7. Turn the sample completely over, be careful not to wrinkle it. The sample was subjected to a teardrop-shaped annular sample ring having a circumference of 98 mm and a patch surface facing outward.

8. Fasten the ends of the sample ring with a 13 mm wide cover tape. 9. Insert the sample ring into the holder to ensure that the sample ring is in the proper position to form the upper assembly.
10. Zero the instrument 11. Changan “electric†button, the upper assembly starts to move downwards. The upper assembly automatically stops 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 sample loop in contact with the test plate to form a bond. Next, the assembly was moved upward at a speed of 300 mm/min ± 10 mm/min, and the dynamometer recorded the tensile force required to pull the sample loop away from the test plate. At the end of a loop, the upper component will return to its original position.
13. Record the large tensile force required to detach the sample ring from the stainless steel test plate and the failure mode of bonding the sample ring to the test plate.
14. The bond failure mode of the sample ring and the test plate is divided into three cases: interface failure, cohesive failure and transfer failure.
15. After the test is completed, clean the stainless steel test plate in the test fixture with the reagent, and cover the stainless steel test plate with a dust-free cloth to prevent the surface from being scratched.
Summary: Online shopping has become a convenient way for people to shop. The paper also mentions that tape is a very important packaging function. The detection of the initial tack of the tape has been paid attention to by the major adhesive tape manufacturers. According to the steps that Xiaobian told everyone, the LT-3000, a circular initial tack tester designed and developed by Jinan Sanquan Zhongshi Experimental Instrument Co., Ltd., can help manufacturers easily solve the initial tack detection of tape.
