Electrical tape, as an essential product for electrical maintenance, almost appears in every electrician's toolbox, but do we really understand it?
Today, we will analyze in detail the three misunderstandings about electrical tape!
Electrical tape, as an essential product for electrical maintenance, almost appears in every electrician's toolbox, but do we really understand it? Today, we will analyze in detail the three misunderstandings about electrical tape!
Myth1: The more sticky electrical tape, the better?
The electrical tape doesn't seem to stick to the touch. Is it of bad quality?
The electrical tape is not wrapped around the hand in the end, and simply touching the tape with your hand to feel the viscosity does not have reference significance. Some poor quality electrical tapes, at the expense of glue cohesion strength, blindly increase the softness of the glue, to achieve a very sticky feel, and in the actual use of the process will bring degumming, overflow and other problems.
Feel sticky ≠ actual use sticky, electrical adhesive tape is not sticky, can not only "touch" to judge!
If you want to increase the stickiness of electrical tape, can you just apply more glue? Not so, blindly apply more glue, may make the feel better, but whether it is unused tape in storage, or wrapped tape, it is more likely to produce overflow phenomenon. Electrical equipment is generally in a higher temperature environment, too much glue will produce more serious glue overflow phenomenon.
Purchase suggestion：
How to control the appropriate amount and proportion of glue, so that the adhesive tape is just right is a learning. LIANTU electrical experts have rich professional experience in the ratio of adhesive coating, LIANTU electrical tape and other products have a long history, to ensure the application of different substrates adhesive at the same time, effectively avoid the problem of rubber spill.
Myth 2: Electrical tape flame retardant
Flame retardant "can't be lit"? No, it's not! "Flame retardant" means the material or material itself, or after treatment has a significant delay in the spread of flame properties. Electrical tape with excellent flame retardant performance is also likely to be lit, but it will be extinguished soon after lighting.
Can electrical tape be tested for flame retardancy by burning it over an open flame?
Often see the test method of open fire electrical tape can indeed partly prove the flame retardant, but this is not the standard test method, and the actual use of electrical tape environment is also different.
Myth 3: How to buy? It's a science, actually
There is nothing trivial about electricity. The purchase of electrical tape, you need to consider various properties, such as viscosity, tensile force, raw materials, flame retardant and so on. Self-test to see whether the electrical tape is good, you can make basic judgments through the following four steps:
1. Watch from the outside to see whether there are defects, whether the tape rewinding is affixed, and whether there is a sudden core phenomenon. Inferior tape core, core part can only be abandoned;
2. Smell the smell, if the glue tastes pungent, it is more likely to be defective;
3. Pull the tape outward to see the ductility; Some tapes have poor tensile properties or longitudinal cracks at the fracture, indicating that the material is poor.
4. After the tape is stuck, tear it off again to see if there is residual glue on the pasted surface, or whether the tape base is degummed.
Purchase suggestions:
LIANTU electrical tape, big brand formula professional, solid material, not easy to overflow and degumming, easy to use, feel good, is your stable choice.
Professional grade cold resistant electrical insulation tape and high temperature electrical insulation tape are available for you to choose from under extremely harsh conditions. Its operating temperature range from -25℃ to 105℃, good resilience, firm adhesion, safe flame retardant, salt spray and acid and alkali resistance, safe to use.
