Ceramic particle adhesive is the main bonding method in construction, and understanding its bonding force principle is helpful for future use. Next, the editor will introduce the principle of ceramic particle glue.
As a two-component polyurethane adhesive, glue has good adhesion and bonding properties, especially adhesion, which is more sticky and firm than other adhesives. The implementation process of its adhesion is divided into two brief stages. The flowing adhesive molecules diffuse to the surface of the bonded object through Brownian motion and gradually approach, while the fluidity (low viscosity) of the adhesive liquid and the application of curing pressure facilitate the contact and approach between molecules.
The generation of intermolecular adsorption occurs when the distance between the adhesive molecule and the surface molecule of the adhered object is close, and the secondary valence force begins to exert a force, which increases as the distance between the adhesive molecule and the surface molecule decreases. These two processes cannot be completely separated, as the adhesive solution continues to work until it solidifies. It can be seen that ceramic particle adhesive can fully contact the surface of the adhered object. The close distance between two molecules is the key to obtaining adhesion. So for similar adhesives, the viscosity of the adhesive itself is relatively high, or it needs to be diluted during the construction process. With the help of Brownian motion heating, pressure during the curing process, and extended curing time (especially for room temperature curing adhesives), a smooth, clean, and dry surface of the adhesive is the condition for obtaining adhesion.
Colored anti-skid pavement mainly uses pavement formed by particles, which is very popular nowadays due to its gorgeous color. In addition, the ceramic particle adhesive used has a certain road protection effect, adding a layer of protection for travel.
In addition, according to the data, it can be concluded that ceramic particle adhesive has good anti-corrosion function, can withstand long-term corrosion from acid, alkali, salt and automobile exhaust, can protect the roadbed from damage, and exert sufficient strength. We know that the cost of road construction is actually very high, which can be said to be huge compared to purchasing ceramic particle glue. Therefore, this is a good way to save money and time, and also saves a lot of labor to complete road construction work. So building roads is better than protecting them. The braking distance has been reduced by more than 45%, and the slipping phenomenon has been reduced by 75%. Now is an era where data speaks for itself, so the data obtained from these two sets of experiments can prove the advantages of glue.
This is the principle of ceramic particle adhesive. The higher the viscosity, the better the effect after construction. This is mainly due to the role of adhesion, ensuring the adhesion and service life of the road surface.
