The working principle of tape is mainly based on pressure and surface adhesion. Tape usually consists of a soft tape back and a sticky adhesive layer. When tape is used to bond two objects, people usually apply pressure on the tape with their hands or other tools to make the adhesive layer close to the surface of the object. Because the adhesive layer is soft, the pressure will deform the surface of limskiktet och fyll det i depressionen på objektets yta, bildar ett större kontaktområde, vilket förbättrar bindningseffekten .
Dessutom är det klibbiga ämnet på ytan av det limskiktet vanligtvis en polymer som innehåller klibbiga komponenter, såsom akrylsyra eller vinylsyra . När dessa klibbiga komponenter kontaktar ytan på objektet, genererar de elektrostatiska attraktion genom intermolekylär adsorption, kombinera vidhäftningen med ytan med ytan att producera en bindning {1 {1 {1})
The composition of tape includes two parts: substrate and adhesive. The substrate provides the structure and strength of the tape, while the adhesive is the key part of the bonding, usually a layer of adhesive coated on the substrate. The earliest adhesives came from animals and plants. With the development of technology, modern adhesives are mostly synthetic Material .
