Manufacturing process of PVC electrical insulation tape

PVC electrical insulation tape refers to the tape used by electricians to prevent electric leakage and play an insulating role. Production process: it is made of PVC film as the base material and coated with rubber pressure-sensitive adhesive.

The insulating tape used by electricians to prevent electric leakage. Also known as PVC electrical insulation tape, tape is composed of baseband and pressure-sensitive adhesive layer.

The baseband is generally made of cotton cloth, synthetic fiber fabric and plastic film. The adhesive layer is made of rubber and tackifying resin. It has good viscosity and excellent insulation performance. The insulating tape has good insulation, pressure resistance, flame resistance, weather resistance and other characteristics, and is suitable for wire connection, electrical insulation protection and other characteristics.

PVC electrical insulation tape is widely used in electrical operations such as binding, joint and insulation sealing of wires used below 380V voltage. There are two production processes: wiping method and gluing method. Production process: it is made of PVC film as the base material and coated with rubber pressure-sensitive adhesive.

In the process of using electricity, although people notice that the cross-sectional area of power line material has an impact on the safe use of electricity, they often pay insufficient attention to the use of PVC electrical insulation tape for joints. At present, the laying of power lines is becoming more and more complex, which can be found under the wooden floor, in the wall, in the partition and in the wet underground or water. If the insulating tape is not used properly, electric leakage will occur and endanger personal safety. Therefore, we should correctly use insulating tape. The power line connector is divided into "+" connection method, "-" connection method, "t" connection method, etc. The joint shall be wrapped firmly, smooth and free of burrs. Otherwise, before the wire head is disconnected, it shall be gently pressed with steel wire pliers, then wound to the crimp, and then swing left and right, and the wire head will be firmly disconnected at the joint. If the joint is in a dry place, it shall be wrapped with insulating black tape for 2 layers, then wrapped with plastic tape for 2 layers, and then stretched by about 200% with insulating self-adhesive tape, wrapped with 2 ~ 3 layers, and finally wrapped with 2 layers of plastic tape.

Because the direct use of plastic tape has many disadvantages: plastic tape is easy to be misplaced and opened over a long time; When the electrical load is heavy, the joint is heated and the plastic tape is easy to melt and shrink; The power connectors squeeze each other in the junction box. When the connector has burrs, it is easy to puncture the plastic tape, etc.

These hidden dangers will directly endanger personal safety, cause short circuit and fire. The above situation will not occur with the use of insulating black tape. It has certain strength and flexibility, can be tightly wrapped at the joint for a long time, is dense and shaped under the influence of time and temperature, will not fall off, and is flame retardant. Moreover, wrapping it with insulating black tape and then wrapping it with plastic tape can prevent moisture and rust.

Of course, the insulating self-adhesive tape also has defects. Although it has good waterproof performance, it is easy to break, so it needs to wrap 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.
