Qingdao tape has many types such as high temperature tape, double-sided tape, insulating tape, special tape, pressure-sensitive tape, die-cut tape, etc. Different functions are suitable for different industry needs, all of which are the credit of tape manufacturers. So what is the reason that tape can bond objects?
Through the adhesive tape, two or several unconnected items can be cleverly connected together. A layer of adhesive is applied to the surface of the tape.

 

The earliest adhesive comes from the animals and plants themselves, rubber It is the most important component of the adhesive. Adhesives widely used in modern times are various polymers. Adhesives can stick things together. It forms a bond between its own molecules and the molecules of the object that you want to connect. This bond can hold the molecules tightly together. The composition of the adhesive is based on different brands and different types of different polymers.
In the process of using tape, make sure that the glue cannot be touched by sharp objects. The tape is fragile and should not be damaged as much as possible. The tape manufacturer said that for the tape that has not been used for a long time, it will not stick so easily. This is because it is dampened after a long time, so what should we do to maintain its stickiness.

The greater the difference between the pH of the adherend and the adhesive, the better the adhesion. Generally, the viscosity of tapePTFE Water Tape Manufacturers items that have been in a high temperature environment for a long time will gradually decrease over time, which is also a factor that affects the stickiness of the tape. When the low temperature reaches -253℃, its adhesion will also decrease. In a hot and humid environment, it will lose strength and hardness due to hydrolysis, and even liquefy in severe cases, so the bonding strength will be reduced under humid conditions.

In this way, we know that for the long-term unused tape, we need to pay attention to its storage. It should be placed in a dry environment. At the same time, we must also pay attention to the influence of temperature. We should not be exposed to the sun for a long time to prevent the high temperature from reducing the viscosity of the glue.
