Although polyethylene adhesive tape has its own position in many fields by virtue of its own advantages, no matter the performance of the product is good, users will always report various problems during use, such as Recently, it has been reflected that the teaching life is getting shorter and shorter, and the degree of aging is getting faster and faster, causing problems when using it for a while. In order to solve this problem, let’s take a look at the adhesive. What are the reasons for belt aging?

  1. Oxygen, because the oxygen content in the air accounts for 21%, and oxygen has the characteristics of accelerating the oxidation of substances, and its activity is heavier, causing rapid oxidation of the polyethylene adhesive tape, which causes the polyethylene tape to become 'old' '. But when we stick the adhesive tape, it is enough not to let the product have bubbles. Of course, for breathable products, this factor is inevitable.

  2. Ultraviolet rays (sunlight). Ultraviolet rays have high-temperature characteristics that can quickly decompose viscous substances. Adhesive tapes exposed to sunlight for a long time will be decomposed by them, causing the adhesive tape to age. This depends on where the product is used, and whether the object is exposed to the sun.

  3. Plasticizers, whose main function is to soften plastics, and most rubber products contain plasticizers. As time changes, the proportion of plasticizers in the substances themselves will increase, resulting in The aging of polyethylene adhesive tape, etc. Under the long-term influence of the above various factors, the adhesive tape will deteriorate, soften, solidify, and lose its viscosity.

  4. Metals, especially brass or rust, in daily life, any organic compound substance can react with metals, especially brass or rust, and the adhesive tape contains organic compounds, thus Lead to aging of the adhesive tape. Many metals will stick the adhesive tape protective film, or some parts need to be used, which requires attention to the life of the adhesive tape to avoid even more serious situations in which the parts fall off due to the polyethylene adhesive tape.

  5. The main component of bleaching agent is calcium oxide. The calcium element contained in it can chemically react with organic compounds. This generally happens rarely.

   The above is the reason for the aging of polyethylene adhesive tape. In fact, if you want to extend the service life of the product when using the adhesive tape, in addition to paying more attention to the above points, the rest is buying When you buy a good quality product, you can effectively increase the service life of the product. Of course, you must follow the correct operating steps when you use it, so as to avoid the use of the product due to improper operation.
