The secret of tape adhesives

It seems that knowing the principles of physics governing the nature of the operation of tape adhesives can not be the key to entering the world of manufacturing, but contrary to what scientists have found, one can find the answer to this question for many questions. Which occupied the minds of the people in this regard, and achieved an acceptable answer.
If you examine the surface of a piece of adhesive tape with a powerful and advanced microscope, you will see that the surface is not flat. On the surface of the adhesive tape, there are sunken spots and protrusions that cannot be seen with the naked eye.
When the surface of the adhesive tape is pressed in contact with the other surface, air bubbles are trapped between the two surfaces and inside the recesses of the adhesive surface.
These air bubbles act like millions of suction units, and because of this, the glue sticks to the desired surface and is difficult to separate from it. To remove the adhesive from the surface to which it is attached, you must release the trapped air bubbles.
To do this, you must gently lift the glue from the paper, because when the adhesive tape sticks to the surface, the air bubbles are sealed in such a way that not even an air molecule can enter any of these bubbles. Find a way. By sticking the adhesive tape on the desired surface, the air pressure inside each of the bubbles and their dimensions are reduced.
This means that the ambient air pressure overcomes the air pressure inside the air bubbles, causing it to adhere better, but if you apply enough force, you can easily remove the adhesive from any surface.
When a small cut or hole is made in the surface of the adhesive, air penetrates to the surface under the adhesive, and the adhesive is easily removed. The adhesive in strip adhesives is different from the adhesive in liquid adhesives.
Unlike liquid adhesives, where the adhesive dries two surfaces or two different pieces after drying; Tape adhesives, as soon as you remove a piece of it, have the ability to glue the desired surfaces or parts together, of course, the type of adhesive used in the preparation of tape adhesives, depending on its application. Is different.
