We buy double-sided tape, mainly with tape fixed bonding things, then the adhesive tape is very important, poor adhesive tape mainly has the following two aspects:
I. Short stickiness time and poor ability to adapt to the environment:
Most adulterated tapes will break apart after a period of packaging (between 20 minutes and an hour) and will not be able to be re-pasted, especially in cold temperatures and windy dry conditions.
Two, the poor double-sided tape is easy to break
Inferior tape is easy to break, the strength is very low, mainly related to the quality of the film.
So how do we choose tape?
One: The first thing to do when you get double-sided tape is to feel whether it is sticky enough with your hands and whether you can feel your requirements.
Two: Put the tape on your nostril and take a sniff. If the smell is smelly or very thick, the quality of glue is not good, it is recommended not to buy.
Three: the same specification (length, width, single-layer thick) tape first look at the thickness of single-layer adhesive paper and tape tensile resistance. Be sure to choose good tensile resistance. Want to see your choice of buyer on ply.
Some tips for choosing tape:
(1), it is necessary to choose not easy to break, high viscosity;
(2) The weight of the adhesive tape should be sufficient;
(3) On the tape, you can press the tape hard with your fingers from the back of the tape. It feels very hard. Then the tape is tight and the number of meters is very enough, which is much longer than the same thickness but the length of the loose tape.
(4) You can see from the side of the tape, the tight tape looks very strong, and the loose tape looks soft and soft, and some even have gaps
