Adhesive label peeling, warping, off operation

1. Labels on Labeling Machines Many manufacturers have found that they often appear to be skewed when they are labeling on automatic labeling machines. This is a problem of initial tack, and the instantaneous adhesive force is not strong. According to the GB4852 pressure-sensitive adhesive tape initial tack test method ( bevel ball method ) , through the use of the inclined ball method, through the steel ball and adhesive label sample adhesive surface The adhesion of the label to the steel ball is used to test the initial tackiness of the sample when a brief contact occurs with a slight pressure. A total of (2002 GB new standards for as long as 29) 33 standard ball ball, the label can stick to the largest steel ball model to represent its tack. This kind of situation can choose to use our HD-525 early viscous testing machine, our company completely according to the latest standard of national standard production.

This product is designed and manufactured in accordance with the provisions of GB/T4852 , applicable to pressure sensitive tape and other related products for initial tack test test.
The product is mainly composed of inclined board, ball putter, bracket, adjustable horizontal base and steel ball. The bead rolling method is used to test the initial tackiness of the sample by the adhesive action of the adhesive tape to the steel ball when the steel ball and the adhesive surface of the pressure-sensitive adhesive tape contact with the adhesive surface for a short time with a slight pressure.
The specific method of operation is to put the sticky surface upside down on a test board with a tilt of 30° . Take the ball from the highest number and make it free. Record the ball number that can be stuck on the test piece for more than 5 seconds.

2. A lot of people sticking to the label have found out that they don't have a long time on their own, and they themselves have no stickiness. This kind of situation is a sticky problem, that is, poor retention, according to GB4851 pressure sensitive adhesive tape holding sticky test method, Using a standard 2 kg roller, the label was pressed against two test boards. A test board with glued specimens was hung vertically on the test stand and the other test board was hung with a 1 kg weight. The ability of the adhesive to resist detachment is characterized by the amount of displacement of the sample after a certain period of time, or the time the sample is completely detached. In this case, we can use our HD-524A holding viscosity testing machine ( holding force testing machine ) , our company completely in accordance with the latest standards of national standard production.

HD-524A Viscosity Tester ( Tape Retention Tester )

Uses: Stick the tape on the test board and hang the standard load on the lower end . After a period of time , measure the tape's sliding distance or tape sticking time to assess the durability of the adhesive tape.

3 , the label is easy to be peeled off to feel the adhesive strength is low and the peel strength is too low according to the GB2792 pressure-sensitive adhesive tape 180 degree peel strength test method, with 2 kg standard pressure roller to label and after cleaning The test plate was bonded, the free ends of the samples were folded at 180 degrees, and the adhesive surface was peeled off from the test plates. The Peel Tester records and calculates the peel strength (kN/m) . In this case, we can choose the machine developed by our company, HD-604 peel force tester or HD-609B-S peel strength tester.

HD-604 peeling force testing machine is widely used in various types of materials such as hardware, metal, rubber, plastics, shoes, leather, clothing, textiles, insulation, wire and cable, terminals, etc., to test its stretching, tearing, peeling, testing the performance was compression, bending shear force, three-point bending ...... like.

Rally machine uses micro DC servo motor as power source, single-chip microcomputer real-time display test data and test status, the control of the test process is achieved through the single-chip microcomputer control.

 

Uses: It can test and analyze the mechanical properties of various metals, non-metals and composite materials. It is widely used in aerospace, petrochemical, machinery manufacturing, wire, cable, textile, fiber, plastic, rubber, ceramics, food, medicine Packaging, aluminum plastic pipe, plastic doors and windows, geotextiles, film, wood, paper, metal materials and manufacturing, can automatically calculate the maximum test force value, fracture force and other test data. The function is introduced as follows: 1) Automatic shutdown: After the sample breaks, the moving beam automatically stops;

　　 2) Automatic calibration: The system can automatically achieve the calibration of indication accuracy;

　　 3) Process realization: Test process, measurement, display, etc. are all realized by the single-chip microcomputer;

　　 4) Limit protection: Program-controlled and mechanical two-level limit protection;

　　 5) Overload protection: When the load exceeds 3-5% of the maximum value of each file , it will stop automatically .
