The Distinction and Industry Advantages of Aluminum Foil Duct Tape
How many types of aluminum foil duct tapes are there, what are the differences between them and how to distinguish them.
Ⅰ. How to distinguish aluminum foil duct tape?
The types of aluminum foil duct tapes are divided into film-coated aluminum foil and pure aluminum foil from the base material. The appearance is divided into unlined aluminum foil duct tape and lined aluminum foil duct tape. The glue is divided into water glue, oil glue, hot melt adhesive, rubber, silicone.
Features are divided into ordinary aluminum foil duct tape, high temperature aluminum foil duct tape, flame retardant aluminum foil duct tape.
The difference between the laminated aluminum foil duct tape and the pure aluminum foil tape is: the pure aluminum foil duct tape is easy to tear, and the laminated aluminum foil duct tape has a certain toughness and is not easy to break, and has good tensile properties, which is more suitable for machine use.
The difference between aluminum foil duct tape with liner and aluminum foil duct tape without liner is: there is a layer of backing paper on the inside of aluminum foil duct tape with liner, and aluminum foil duct tape without liner is peeled off and used directly like the transparent tape we usually use.
It is difficult for people who do not understand the technical content of the glue system to distinguish the glue system. Only those who have special requirements for glue will pay attention to the glue system. The most used in daily life is the water glue aluminum foil duct tape. If you subdivide it further, there are many kinds of aluminum foil. Mainly according to the production demand and technical requirements to choose the suitable aluminum foil duct tape.
Ⅱ. The industry advantages of aluminum foil duct tape
Aluminum foil duct tape is mainly based on aluminum foil, coated with acrylic glue, with high peel strength, excellent adhesion, oxidation resistance, corrosion resistance and flame resistance. Since it is made of high-quality pressure-sensitive adhesive, it has the functions of good viscosity, strong adhesion, and anti-aging.
1. Suppress battery polarization, reduce thermal effects, and improve rate performance;
2. Reduce the internal resistance of the battery, and significantly reduce the dynamic internal resistance increase in the cycle process;
3. Improve consistency and increase battery cycle life;
4. Improve the adhesion between the active material and the current collector, and reduce the manufacturing cost of the pole piece;
5. Protect the current collector from being corroded by the electrolyte;
6. Improve the processing performance of lithium iron phosphate and lithium titanate materials.
Aluminum foil duct tape not only uses different materials from other tapes, but also can eliminate electromagnetic interference and isolate electromagnetic waves from harming the human body. Therefore, in many electronic products and some important industrial fields, aluminum foil duct tapes are generally used.
It is precisely because of its unique advantages and different materials that it is more expensive than other tapes.
