绝缘胶带是指电工用来防止泄漏和绝缘的胶带。
又称绝缘胶带，胶带，由基带和压敏粘合剂层制成。
基带通常由棉，合成纤维和塑料薄膜制成。橡胶层由橡胶和粘弹性树脂制成，粘合性好，绝缘性好。
绝缘胶带具有良好的绝缘电阻，阻燃和电阻等特点，可用于电线连接和电绝缘保护。
绝缘胶带广泛用于电线的电气工作，如绷带，接头和380V以下使用的电线绝缘。
有两种橡胶和胶水。
Manufacturing process: made of polyvinyl chloride film as base material, coated with rubber pressure sensitive adhesive.
In the process of electricity consumption, people have noticed that the size of the power cord material has an impact on the safety of the electric, but it is often used to pay less attention to the use of insulating tape.
The power line is more and more complicated, the floor under the floor, the wall, the partition and the wet underground or the water.
If the insulation tape is improperly used, leakage will occur, endangering the safety of the person.
So we need to use the insulation tape correctly, and the power connector is divided into "+", "-", "-", "T", and so on.
Joint should be bound tightly, smooth and no burr, otherwise, before the thread broken, should press gently with combination pliers, first round to the inlet pressure, then side, thread will break in disconnect joint.
If the joint is in a dry place, the two layers of insulation black tape should be used first, then the plastic tape will be used for 2 layers, then the insulation will be extended by about 200%, and the two or three layers will be wrapped, and then the two layers of plastic tape will be wrapped.
There are many defects in the direct use of plastic tape: plastic tape time is easy to misplace and gelatine;
When the electrical load is heavy, the joint is hot and the plastic tape is easy to melt and shrink.
The power connector squeezes each other in the junction box, and it is easy to puncture the plastic tape when the joint has burr.
These hidden dangers will directly endanger the safety of the person, causing the circuit short circuit, causing fire.
And use black insulation tape will not appear the above situation, it has a certain strength, flexibility, can tightly around tapping for a long time, affected by time and temperature and compact shape, will not fall off, and flame retardant.
In addition, plastic tape can be used to prevent moisture and rust.
绝缘胶带当然也有缺点，防水性能好，但容易断裂，所以需要捆绑作为保护层，第2层塑料胶带在接头绝缘和接头粘接剂上其他不粘，性能更好。
