Describe the manufacturing process of PVC electrical insulation tape

We all know that there are many kinds of adhesive tapes. Next, I will share with you a kind of PVC electrical insulation tape produced by the adhesive tape factory> PVC electrical insulation tape, hoping to bring some help to you. PVC electrical insulation tape specifically refers to the tape used by electricians to prevent leakage and insulate. Manufacturing process: it is made of polyvinyl chloride film as the base material and rubber pressure sensitive adhesive. PVC electrical insulation tape produced by tape factory refers to the tape used by electricians to prevent leakage and insulate. Also known as insulating tape, tape, composed of baseband and pressure sensitive adhesive layer. The baseband is generally made of cotton, synthetic fiber fabric and plastic film. The adhesive layer is made of rubber and adhesive resin, which has good viscosity and excellent insulation performance. PVC electrical insulation tape has good insulation pressure resistance, flame retardant, weather resistance and other characteristics, suitable for wire connection, electrical insulation protection and other characteristics. PVC electrical insulation tape produced by tape factory is widely used in electrical operations such as wire binding, joint, insulation sealing, etc. used under 380V voltage. There are two kinds of production processes: wiping glue and coating glue. Manufacturing process: PVC film is used as the base material and coated with rubber pressure sensitive adhesive. In the process of electricity consumption, although people have noticed that the cross-sectional area of power cord materials has an impact on the safe use of electricity, they often do not pay enough attention to the PVC electrical insulation tape produced by the adhesive tape factory for joints. At present, the laying of power lines is becoming more and more complicated, including under the wood floor, in the wall, in the partition board and in the wet underground or water. If PVC electrical insulation tape is not used properly, leakage will occur, endangering personal safety. Therefore, we should use PVC electrical insulation tape correctly. The power cord connector is divided into '-', '-' and 'T. The joint should be tightly wrapped, smooth and free of burrs. Otherwise, before the line head is disconnected, it should be gently pressed with a wire cutter, then wound to the pressure opening, and then left and right, the thread will be disconnected at the joint. If the joint is in a dry place, first wrap 2 layers with insulating black tape, then wrap 2 layers with plastic tape, then use insulating self-adhesive tape to lengthen about 200% and wrap 2 ~ 3 layers, 2 layers of plastic tape wrapped behind. Because the plastic tape produced by the tape factory has many disadvantages: the plastic tape is easy to be misplaced and opened for a long time; When the electrical appliance is under heavy load, the joint heats up and the plastic adhesive tape is easy to melt and shrink; The power connectors are squeezed into each other in the junction box. When the connectors have burrs, it is easy to puncture the plastic tape.
