What is tape?
The full name of electrical tape is PVC electrical insulation adhesive tape, which is also called electrical insulation tape or insulating tape. Abbreviation: PVC electrical tape, PVC tape, etc It has good insulation, flame resistance, voltage resistance, cold resistance and other characteristics. It is suitable for wire winding, insulation and fixation of various motors and electronic parts such as transformers, motors, capacitors, voltage regulators and so on. There are red, yellow, blue, white, green, black, transparent and other colors.
Instructions for use of electrical tape:
The power line connector is divided into "ten" connection method, "one" connection method, "t" connection method, etc. The joint shall be wrapped firmly, smooth and free of thorns. Before the thread head is disconnected, it shall be gently pressed with a steel wire pliers, then wound to the mouth, and then swing left and right, and the thread head will be disconnected at the joint. If the joint is in a dry place, it shall be wrapped with two layers of insulating black cloth, then two layers of plastic tape (also known as PVC adhesive tape), then lengthened by about 200% with J-10 insulating self-adhesive tape, wrapped with two or three layers, and finally wrapped with two layers of plastic tape. Because the direct use of plastic tape has many disadvantages: the plastic tape is easy to dislocate and open the raw rubber after a long time; when the electrical load is heavy, the joint is hot, and the plastic electrical tape is easy to melt and shrink; the power connectors press each other in the junction box; when the connector has burrs, it is easy to poke the plastic tape. These hidden dangers directly endanger personal safety, cause short circuit or abnormality of the line, and cause fire.
The above situation will not occur with insulating black tape. It has certain strength and flexibility, can wrap the joint tightly for a long time, is dry and fixed under the influence of time and temperature, will not fall off, and is flame retardant. In addition, wrapping with insulating black tape and then wrapping with adhesive tape can prevent moisture and rust.
However, the insulating self-adhesive tape also has defects. Although it has good waterproof performance, it is easy to break, so it needs to be wrapped with two layers of plastic tape as a protective layer. The insulating self-adhesive tape of the joint and the joint is not sticky to each other, and the performance is better. Learn how to use electrical tape, use it correctly, prevent electric leakage and reduce harm.
What is identification tape?
The identification tape (warning tape) is made of PVC film as the base material and coated with rubber pressure-sensitive adhesive.
What is the purpose of identification tape?
Pasted on the ground, wall and machine for prohibition, warning, reminder and emphasis.
When the identification tape is used for area division, it is called marking tape; When used as a warning, it is called warning tape. But in fact, both are the same thing. When used for area division, there is no relevant standard or conventional saying to specify what kind of area needs to be divided by what color. Green, yellow, blue and white are widely used. When used as a warning, according to GB 2893-2001 "safety colors" and the warning signs of occupational hazards in the workplace issued by the Ministry of health in 2003, monochromatic red, yellow, green and two-color red and white, green white and yellow black can be used as warning lines. Here, we suggest making a distinction between marking tape and warning tape. White, yellow and green are used for marking; Red, red white, green white and yellow black are used as warnings.
When used as a warning, red indicates prohibition and prevention; Red and white stripes indicate that people are not allowed to enter the dangerous environment; Yellow and black stripes mean to remind people to pay special attention; Green and white stripes indicate more eye-catching tips.
It is used to identify warning areas, divide Danger Warnings, label classification, etc.
There are black, yellow, red and white lines to choose from. The surface layer is wear-resistant and can withstand high flow pedal.
Good viscosity, certain anti-corrosion, acid-base resistance and wear resistance.
