Electrical tape full name for the PVC insulation adhesive tape, electrical tape it was called electrical insulation tape or insulation tape. The electrical tape is suitable for the insulation of various resistance parts. General electrical insulation tape has three kinds, one is insulated black tape, the second is pvc electrical flame retardant tape, the third is the high-pressure self-adhesive tape, electrical tape three of each have their own functions. In the purchase of electrical insulation tape, how to determine the electrical insulation tape is good or bad? What kind of electrical tape how to determine the electrical insulation tape is good or bad Electrical tape classification Electrical insulation tape is divided into three types:
One is insulated black tape, electrical tape only the insulation function, but not fire-retardant is not waterproof, and now has been gradually eliminated, and only in some civil construction electrical also some people in use.
The second is pvc electrical flame retardant tape, it has insulation, electrical tape flame retardant, and waterproof three functions, but because it is pvc material, so the ductility is poor, can not be wrapped very tight joints, water resistance is not very good, But it has now been widely used. The third is the high-pressure self-adhesive tape, generally used in the higher level of voltage, electrical tape because of its good ductility, waterproof than the second better, so people also apply it in low-voltage areas, but because Its strength is not as good as pvc electrical flame retardant tape, usually these two kinds of use
Electrical tape quality identification from the outside to see if there are flaws, tape rewinding is obedient, cut whether there is no flash, whether the smooth look at the tape material (electrical insulation tape there are many types, not one by one to introduce the material quality evaluation, in the majority The situation has to see the use of the situation) to see the glue, and now most of the glue has been evolved to the environmental protection, electrical tape the taste is very important, if it is pungent, is the possibility of defective product is relatively large (not all tape), Under the use of anti-stick, there is no tear after the use of residual glue, if the residual glue on the product, this is the defective tape Note that the PVC material is basically the same,electrical tape mainly to see the plastic, poor quality bandage After a period of time, and then unlock, you can see the glue and PVC material separation, looks sticky, very uncomfortable, and good quality tape will not appear this problem.
1. General use of bright and cold special bright type, thin film, computer gravure printing, insulation is good.
2. Strong viscosity, surface wear resistance, electrical tape can withstand high flow foot; have a certain anti-corrosion, acid and alkali performance, anti-wear.
3. Compared to the ground painting, simple operation, paint can not draw a two-color line specifications.
4. Can not only be used in ordinary ground, electrical tape can also be used in wood flooring, cement floor, tiles, marble, walls and machines (and ground painting can only be used in ordinary ground).
5. Tape should be deposited into the Treasury, to avoid the sun, rain; prohibited with acid and alkali oil organic solvent contact, keep clean and dry, room temperature -10 ℃ ~ 60 ℃ between.
Applicable to the normal working temperature does not exceed 80 ℃, operating in 10KV and below the rubber cable terminal and the middle of the insulation protection and communication cable connector insulation seal.
Can be heat, ozone resistance, aging resistance, electrical tape chemical resistance, and shock absorption, electrical insulation properties. Good resistance to sunlight and ozone can be exposed to animal or vegetable oils or oxidizable chemicals.
