How is glue produced?

the reason why glue can produce viscosity and stick the two articles together is because the effective substance in the glue forms a solid adhesive layer in the process of volatilization of the water in the glue. When it acts on the two articles, it plays the role of bonding. The effective substances in different glues are also different. For example, we often use liquid glue. When we apply the glue between the papers, the water in the glue begins to volatilize. Finally, the effective substance polyvinyl acetate is left to coagulate and firmly stick the two papers together

the effective substance of 502 strong glue we commonly use is α- Ethyl cyanoacrylate, but the mixture is not water. Instead, it needs to contact with water vapor in the air before it can produce strong viscosity. This glue has fast reaction speed and good viscosity, but it must be sealed and stored, otherwise it will easily fail after contacting with air. Therefore, the content of each 502 glue we see is very small, and it is completely sealed and packaged

now many students no longer use liquid glue, because it is not only difficult to operate, but also easy to drip on clothes, exercise books, desks and hands, so solid glue has become the mainstream in stationery stores. Maybe in the future, we will have more advanced bonding technology, so that we can more easily combine the two items together.
