When talking about Glue, I believe that everyone must be familiar. Glue is one of the most important products, and its appearance makes it easy for us to paste things. But what exactly is glue? How is glue classified?
What is glue? Glue is a substance that can adhere to two objects.
It mainly relies on the tensile force between the polymer bodies in the glue to achieve bonding. The polymer body is generally round particles with a radius of 0.5 to 5 μm. The water in the glue is the carrier of the polymer, and the water carries the polymer slowly into 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. It is worth noting that in the use of glue, if the amount of glue is too much, the polymer in the glue will be crowded together. There will be 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.
How is the glue classified? There are many types of glues. According to physical form, they can be divided into solvent-free liquids, organic solvent liquids, water-based liquids, pastes, powders, granules, blocks, flakes, membranes, meshes, belts.
According to the attribute classification of the Adhesive material, it can be divided into animal glue, vegetable glue, inorganic matter and mineral, synthetic elastomer, synthetic thermoplastic material, synthetic thermosetting material, thermosetting, thermoplastic material and elastomer composite.
Glues commonly used in office are classified into solid glue, liquid glue, and 502 Glue. Solid glue is a kind of ideal and beautiful adhesive. It is used to inject hot liquid into the mold, cool it and turn it into a solid, and put it into the lipstick tube to form a solid adhesive.
The appearance is like a cosmetic. Lipstick. It is easy to carry and use. When using it, screw the base body. After the glue stick is slightly exposed, you can apply it. The production is simple, the raw materials are easy to purchase, and the cost is low. 502 glue is based on ethyl cyanoacrylate, adding tackifier, stabilizer, toughening agent, polymerization inhibitor, etc.
The single component instant curing adhesive synthesized by advanced production technology is convenient to use, and the viscosity is very high.
There are also small series to remind you, if the ordinary glue is accidentally contaminated on the clothes, soak it with some oily things, then wash off the oil with a lot of washing powder.
If 502 glue is accidentally contaminated on the clothes, add 502 glue to soften it in the original place, then wash it with water quickly, or apply acetone, and wait about 5-10 minutes to remove it.
I hope that the introduction can help you understand a lot of knowledge about glue. Be careful when using glue. Don't stick to your body or somewhere else.
