How to identify the quality of duct tape

1. Touch the cloth tape on the glue side with your hand, and then move with your hand on the plane of the cloth tape, if the hand feels the resistance from the adhesive tape glue, and the sticky resistance is quite large, it means that the initial adhesion of the cloth tape is quite good. Under normal circumstances, if the adhesive of the duct tape is not good, it will not stick to things.

2. Check the side without glue, whether the surface is clearly lined up and arranged in a neat and orderly manner, and the thickness of the cloth tape is relatively thick. If such a duct tape is used, the tensile strength of the duct tape is stated.

It is larger and more able to withstand the pulling force of heavy items. If the texture is relatively rare, then the tension of this cloth tape to withstand heavy items is not so great.

3. Tear the cloth tape by hand, if the cloth tape is relatively easy to be torn off, then the base material of the cloth tape is good, because the cloth tape itself is to be used well, and the operability is relatively strong, on the contrary, if the base material of the cloth tape is not good and not easy to tear, then the cloth tape is not very easy to operate.

The main thing is to look at the viscosity, many tapes will not stick after a period of time, but this is not the only standard. There are some other conditions that can be looked at the thickness of the tape paper core first, and the thickness of the standard paper core is 3mm. Looking at the diameter of the paper core, the standard diameter is.

Smell the tape, if it smells loud or smelly, it is not of good quality.

Check the surface of the tape, including whether the two sides of the tape are sticky and whether there are gaps, the two sides of the tape are not sticky and there are no gaps.

Check whether there are air bubbles on the surface of the tape, the tape is rolled very tightly and there will be no bubbles, of course, if it is a new tape, there may be a little bubbles.

Check the tension of the tape, if the tape is particularly easy to break, it is inferior quality. Good tape is not easy to break when using a good transparent film.

The most important thing is to check the viscosity of the tape. There are also many ways to inspect the box, you can seal the box with tape, and then withdraw it suddenly, the more you can peel off the surface of the box, the better the stickiness. You can also pull a relatively long section of tape, divide it into two, fold it in the middle position and fit it fully, and then pull it up suddenly, if the tape is not pulled up or part of the tape breaks during the tape pulling up, it means that the stickiness is strong.

1. Cloth tape is based on the thermal composite of polyethylene and gauze fibers. Coated with high-viscosity synthetic glue, it has strong peeling force, tensile strength, grease resistance, aging resistance, temperature resistance, waterproof, and anti-corrosion, and is a kind of high-viscosity tape with relatively large adhesion.

Second, the role of cloth tape.

1. It is generally used for carton sealing, carpet seaming, heavy-duty bundling, waterproof packaging and other purposes.

2. So far, cloth tape has been frequently used in the automotive industry, paper industry, mechanical and electrical industry, mainly in automobile cabs, chassis, cabinets and other places with good waterproof measures.

3. It is easy to perform die-cutting processing in the die-cutting industry.

3. The difference between cloth tape and ordinary tape.

1.First of all, let's look at the appearance of the duct tape is based on the easy-to-tear cloth, and then the corresponding adhesive is applied to the inside of the tape. The texture is delicate on the outside, and there are many kinds of colors.

The ordinary tape we call is different, the ordinary tape we call generally refers to the transparent sealing tape, which is a tape formed by using a transparent film as the substrate and evenly coated with acrylic butyl ester glue as the adhesive on the inside. These two kinds of tape are not the same tape at all.

2.Secondly, we can understand in terms of their main uses. The main function of duct tape is to be used in the exhibition to connect the role of carpet, as well as outdoor pipes, some packaging and other aspects of this role. The tape of ordinary tape is mainly used for sealing and packing.

The cloth tape is based on cloth, coated with glue, easy to tear by hand, easy to use, strong tensile strength, waterproof and temperature resistant; It is generally used for box sealing, carpet edge banding, plastic film fixing and so on.

Ordinary tape generally refers to BOPP tape or transparent tape. The two are very different in appearance and different in use.

The difference between cloth tape and ordinary tape is that Shaoxing Hengyang tape The main material of cloth tape is high in composition and easy to tear, also called carpet tape, for example, red cloth tape is used to glue the red carpet for marriage; There are many types of ordinary tapes, such as PVC, rubber, and transparent BOPP tapes, and their uses are also different.

Cloth tape and ordinary tape material is not the same and waterproof, cloth tape tensile toughness is much stronger than ordinary tape, stickiness is mainly gluing, cloth tape market is most commonly used is 70 mesh, viscosity 280U, and OPP ordinary tape market is most commonly used is the viscosity is about 50U.

Cloth tape with gauze as the base material, according to different applications can be coated with hot melt adhesive, rubber and other glue, with hand tearing, high viscosity, waterproof and other properties (some manufacturers produce cloth tape does not fall off the glue, such as Haixiang Star), widely used, can be used for sealing, light packaging, bundling, repair pipes, edge banding exhibition carpets, etc. Ordinary tape generally refers to BOOP tape, which is a commonly used transparent tape that can be used for sealing.

There is a big difference, the cloth is generally used in the exhibition edge sealing carpet, also known as waterproof tape, Haixiang is sold.

Duct tape is breathable, and ordinary tape can be waterproof but not breathable.

Duct tape is a particularly cost-effective product. The duct tape is composed of two parts, the surface layer is polyethylene, and the waterproof and wear-resistant function of the cloth tape is supported by it; The inner layer is a combination of cloth coated glue, which is tensile and easy to tear, and depends on them for resistance, temperature resistance and strong viscosity. The use of duct tape is very down-to-earth:

It can be bundled with heavy objects, can adhere to rough surfaces, such as splicing exhibition carpets, sealing the edges of exhibition carpets, and can be quickly removed; The best water leakage at home can be repaired with cloth tape first, you can make sealing tape for heavy objects, you can wrap wire harnesses, cloth tape is a shining star in industrial tape! Don't look at it so tensile resistant, during the operation, without props, it can be torn apart from the side, which is quite convenient! Colored cloth tape is brightly colored and can be used for identification.

Duct tape.

Duct tape is based on the thermal lamination of polyethylene and gauze fibers. It has strong peeling force, tensile strength, grease resistance, aging resistance, temperature resistance, waterproof, and corrosion resistance, and is a kind of insulating high-viscosity tape.

According to different glues, cloth tape can be divided into hot melt cloth tape and rubber cloth tape.

1.Whether there are flaws from the outside, whether the tape is rewound or not, whether there is a burr in the slitting, and whether it is smooth 2Look at the tape material "There are many types of electrical industrial tapes, so I will not introduce the quality of the material one by one, and in most cases it depends on the use of 3

Looking at the glue, now most of the glue has evolved to environmental protection, the taste is very important, if it is very pungent, it is a relatively large possibility of defective products "does not refer to all tapes, is there any anti-sticking when the tape is pulled down and used, and there is no residual glue after use, if the residual glue is on the product, this is the fatal point of the defective tape Precautions? PVC material is basically the same, mainly to see the glue, poor quality tape after a period of time, and then unwrap, you can see the separation of glue and PVC material, it looks sticky and very uncomfortable, and the tape will not have this problem.
