The principle of adhesive tape and introduction
everyone not unfamiliar, the tape should be basic everyone used, but not necessarily everyone know why tape to stick things? The problem, of course, because of its surface coated with a layer of adhesive relationship! The earliest adhesive from animals and plants, in the 19th century, rubber adhesive is the main ingredients; While modern widely used all kinds of polymer. Adhesive to stick to things, it is because of itself and to connect objects of molecules between the formation of bonding, the bonding can put the molecular firmly sticking together. Adhesive composition, according to the different brand, different types, there are different kinds of polymers.
tape is introduced: BOPP ( Two-way stretch polypropylene) Tape is any enterprise, company, personal life indispensable things, to tape industry has not been a perfect standard, only an industry standard 'QB/T 2422 - 1998 with BOPP sealing pressure-sensitive adhesive tapes. Tape is on the basis of the original film BOPP after high voltage corona makes a rough surface coated with glue after after a article points into small volume is our daily use of adhesive tape. Tape glue is acrylic resin glue, also called pressure-sensitive adhesive, was mostly fat tincture. Tincture of fat is a kind of polymer material, temperature had certain influence on molecular activity. Glue the tincture of fat content directly affects the usage of duct tape. Normal packing tape at the beginning of the viscous force in 13 or more ( Ball number) Between the tape glue thickness are generally of 22 micron. The thickness is standard. Tape according to the effect of his points can be divided into: high temperature tape, double-sided tape, electrical tape, special tape - Pressure sensitive adhesive tape, die cutting tape, anti-static tape, warning tape, anti-static demand different effect for different industry.
