Adhesive-tape includes a ribbons strip of a very versatile material that has been treated on one or both sides with a type of short-term glue. A certain degree of tape's capability to stick things together is due to the cohesive power of the tape itself, but it is the adhesive that makes the tape to stick. How the tape sticks or holds things together is derived by scientific properties of the glue stick which is been used to manufacture tape.
Why Adhesive Tapes?
Adhesive tape is a necessary, useful product. Without adhesive tape, little tasks such as connecting or sticking items together would be complicated to accomplish. If you end up out of adhesive-tape, you can make your own. These are made using huge devices with pressure-sensitive adhesive applied to flat materials.
Principle: There are three aspects to be considered while studying the principle
Van Der Waals Force: The sticking ability of tape depends on the molecular bonding and this phenomenon is Van Der Waals theory of attraction and repulsion i.e. the force which is exerted by two surfaces on each other when they are made to contact. For instance, if we keep two metal pieces in contact, there would be less van der waal's force, but in case of adhesive, with the help of applied pressure made to exert more van der waals force and hence making to stick to each other.
Applied Pressure Force: Pressure triggers the sticking on tape. Essentially, the better you press, the more it will stick. Pressure-sensitive glues, as they are known, connection with some areas better than others. Furthermore, they perform better at average temperature ranges, because the molecular structure of most pressure-sensitive glues starts to come down at very high or low temperature ranges.
Molecule Bonding Factors: A number of aspects can impact van der Waals force, and therefore, the potency of sticker. As described, temperature range is one key aspect. moisture is another; most pressure-sensitive glues do not bond to wet or wet areas because the adhesives' elements will bond with water elements rather than those of the focused surface area. The type of glue can impact bonding power, as well. Duct tape uses far more powerful glues than masking up. Furthermore, broader tape includes more area and has a greater chance of developing a practical van der Waals force.
All the above factors impact on the adhesive tapes and to make them perfect.
