Causes of tape aging

Publish Time: 2020-10-14   Views:
Adhesive tape is very popular and supported by consumers in our life, but do you know what causes the aging of our adhesive tape after use? The following tape manufacturers to give you a popularization of what is the reason for it!
1. Oxygen, because the content of oxygen in the air accounts for 21%, and oxygen has the characteristics of accelerating the oxidation of substances, and its activity is very heavy, resulting in the rapid oxidation of the tape, resulting in the "aging" of the tape. However, when pasting the adhesive tape, it is OK to avoid bubbles on the adhesive tape. Of course, for the breathable tape, this factor is inevitable.
2. Ultraviolet (taiyangguang). UV has high temperature characteristics and can quickly decompose sticky substances. The adhesive tape exposed to sunlight for a long time will be decomposed by it, resulting in aging of the tape. This depends on the place where the tape is used. It can prevent objects from being exposed to the sun.
3. The main function of plasticizer is to soften the plastic. Most of the plastic products contain plasticizer. With the change of time, the proportion of plasticizer in the material itself will increase, resulting in the aging of the tape. Under the long-term influence of the above factors, the tape will deteriorate, soften, solidify and lose its viscosity.
4. Metals, especially brass or rust, can react with metals, especially brass or rust, in daily life, and the adhesive tape contains organic compounds, which leads to the aging of the tape. Many metals will be pasted with adhesive tape protective film, or some parts need to be used. Therefore, we need to pay attention to the service life of the adhesive tape, so as to avoid parts falling off or even more serious situation caused by adhesive tape.
5. Bleaching agent, the main component of which is calcium oxide, which can react with organic compounds. This usually happens rarely.
