Glue, glue daily life is essential supplies, they play their own role in different places, and some families have only glue, but when bonding thing, you need to use glue. So, how do solid glues make glue? Below, Xiaobian brings you a detailed introduction.
How to make glue for solid glue? Take a little bit of solid glue and heat it in water to melt it, then cool it and put it in the bottle.
Glue is a substance that can bond two objects. Glue does not exist independently, it must be applied between two objects to achieve bonding. The chemical composition of the glue is in an aqueous environment. The polymer in the glue (vinyl acetate in white glue is a kind of petroleum derivative) is a circular particle, and the radius of the general particle is between 0.5 and 5 μm. The bonding of objects is achieved by the pulling force between the polymers in the glue. In the glue water, water is the carrier of the medium polymer, and the water carrying the polymer body is slowly immersed in the tissue of the object. When the water in the glue disappears, the polymer in the glue relies on the mutual pulling force to tightly bond the two objects together. In the use of glue, too much glue will cause the polymer in the glue to crowd together; there is no good tensile force between the polymers. The polymers are crowded together, so that they do not form the strongest attraction to each other. At the same time, the moisture between the polymers is not easily volatilized. This is why the thicker the film, the worse the bonding effectiveness of the glue during the bonding process. If the amount of glue is too much, the glue will play a role of "filling" instead of bonding. The bonding between objects is not the glue of glue, but the "cohesion" of glue. If it is not water-soluble, the principle is similar. It is to replace the water with other solvents.
The process of how to make glue for solid glue has been introduced in detail. The adhesiveness of the glue is affected by the season and the weather, and the bonding effect is also different.
