I believe you will not be unfamiliar with tape, but do you know what role our tape plays? Next, the Hefei New Era Adhesive Tape Factory will discuss with you the main role played by the tape!
First of all, tape can be used to seal and secure various products. Then, it can also provide protection during the production process. Thirdly, it is widely used for the structural bonding of metal, plastic, glass, ceramics and other materials, such as the fixing of plastic parts of electronic products, laminated glass and so on. If it is an anti-static tape, it is used as a warning for static-sensitive products or anti-static areas; there is also an anti-static warning floor tape for anti-static areas, containing warning slogans in Chinese and English.
In the 20th century, only a few countries in the world used it, and the materials were very expensive. It only appeared in countries with relatively developed military industries such as the United States and the Soviet Union, and it was only used in aerospace science and technology. This technology is more technically confidential to other countries.
Adhesive tape is mainly used for sealing and protecting various products. Can provide protection during the production process. Adhesive tapes are widely used for the structural bonding of metal, plastic, glass, ceramics and other materials, such as the fixing of plastic parts of electronic products, laminated glass, etc.
Anti-static tape is mainly used as a warning for static-sensitive products or anti-static areas. Anti-static warning floor tape is mainly used in anti-static areas and contains warning slogans in Chinese and English. Feel with your hand whether the adhesive tape is strong enough and whether it meets your requirements;
Look at whether there are impurities in the tape, whether it is transparent adhesive or double-sided tape. How long the impurities indicate the inferior quality of the tape;
Put the tape under the nostrils and ask about the smell, especially when choosing high temperature tape. If the smell is stinky or strong, it means that the quality of the glue is not good. It is recommended not to buy; high temperature tape of the same specification, you should look at the single-layer tape first The thickness of the tape and the tensile strength of the tape are better in comparison.
There are two criteria for the quality of adhesive tape in use, one is the initial adhesion, the other is the retention, and the two are inversely proportional. Under normal circumstances, the adhesive force is lower than the 10th tape, the glue coating is less, generally only about 20 microns, such as stationery tape, ordinary tape used for promotion bundling. The initial adhesion of normal sealing tape is between 15 and 20, and the thickness of this tape glue is generally 22-28 microns. It is the thickness that meets the standard. However, most of the tapes on the market are mixed with impurities, so the thickness increases. In order to hide the impurities, the glue is also mixed with toner, so the scotch tape appears egg-yellow and light green. This kind of tape is generally inferior.
For colored tape, it is generally yellow and khaki. Pinch the sticky and quickly pull it apart, you can pull off the glue on one side, and you can see the purity and transparency of the original film. You can also look at the thickness of the glue. If no glue is pulled apart or pulled apart in dots, there are a lot of impurities in this glue, and the glue has no cohesion. The second is that the moisture is too much and has been volatilized. At this time, the initial adhesion of this tape has dropped very much, and the hand feel can be distinguished. In fact, there are many ways to distinguish between good and bad tape. As long as you pay more attention in your life, you can tell whether the tape is good or bad.
