Adhesive tape factory to share with you the glue and glue and kraft paper tape
Tape believes everyone not unfamiliar, but you know what our tape is mainly played a role? Hefei below tape factory to discuss with you the tape main role!
First of all, the tape can be used for sealing of fixed protection products. Then, it can also provide protection in the process of production. Again, it is widely used in metal, plastic, glass, ceramics and so on the many kinds of adhesive materials of architecture, such as electronic products, plastic parts of fixed, laminated glass, etc. If is anti-static tape, it is used for electrostatic sensitive products or anti-static area warning role; And still antistatic warning tape is used for anti-static floor area, contained in, the warning signs.
And only a handful of countries in the world in the 20th century, the material is very expensive, only in the military industry more developed countries, such as the United States and the Soviet union have appeared, and its only used in aerospace science and technology. The technology of other countries is confidential.
Adhesive tape is mainly used for sealing of fixed protection products. Provide protection in the process of production. Tape is widely used in metal, plastic, glass, ceramics and other bonded materials of architecture, such as electronic products, plastic parts of fixed, laminated glass, etc.
Anti-static adhesive tape is mainly used for electrostatic sensitive products or anti-static area as a warning role. Anti-static warning tape is mainly used for anti-static floor area, containing the medium and the warning signs. With the hand feel the tape sticky not strong enough, whether meet your requirements;
to see whether there are impurities, tape whether cellophane tape or double-sided adhesive, how long the impurity illustrates the tape of the inferior;
put tape on the nostril XiaWen smell, especially when selecting a high temperature adhesive tape, if smell stink or very strong glue quality is bad, suggest not to buy; Same specifications of the high temperature tape, should see the thickness of the single gummed paper and adhesive tape applied first, in contrast to choose applied for good.
Tape glue is good or not in use, there are two standards, one is the initial moisture, one is the retention, is inversely proportional to both. Generally viscous force less than 10 fewer tape glue in accordance with the teaching, generally only about 20 microns, such as stationery adhesive tape, ordinary promotional bundled with the tape. Normal packing tape at the beginning of the viscous force in 15 Between 20, generally speaking, there are 22 - the tape glue thickness 28 micron. The thickness is standard. But most of the tape on the market are mixed with the impurities, so the thickness increases, for shelter impurities, glue is mixed with the pigments, so transparent tape will appear the egg yellow, light green, this tape is generally inferior.
To the color tape, the average is more yellow and yellow. Will be sticky pinched and then quickly pulled open, can be on one side of the glue to pull out, you can see the purity of the original film and transparency. Also can see the thickness of glue, if there is no glue is opened or dot, this glue is in a large number of impurities, glue no cohesion. Second, too much water, has been volatile, viscous fluid at the beginning of this tape has fallen so much that feel is able to distinguish. Actually tape quality distinguish there are a number of methods, as long as more attention to in the life, can distinguish the stand or fall of tape.
