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 tape12mm Width Teflon Tape for Water Pump. 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 colloid 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 damp due to the longer time. So what should we do to maintain its stickiness.
The greater the difference between the pH value of the adherend and the adhesive, the better the adhesion. Generally, the viscosity of tape items that are exposed to high temperature 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 adhesiveness 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 in wet 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.
