With the changes of the times, the development of architectural coatings is also changing with each passing day.
In recent years, more and more engineering exterior walls have gradually used water-based industrial paints.
Water-based industrial paints can meet today's environmental protection and energy saving requirements.
More importantly, the simulation degree of water-based industrial paint can reach more than 96%, which is a leap forward in the construction of wall decoration.
So what are the general problems in the construction of water-based industrial paint?
1.
Water-in-water whitening: The main material is fully dried after construction and then coated with com" href="http://">paint online coatingol.
com .
The top coat should be of good quality and don't save materials.
All of these can improve this problem, but in the final analysis it is a material problem.
This problem can be solved by working hard on the main material.
2.
Cracking problem: Although this kind of water-based colorful paint has anti-cracking properties, it cannot be used alone to achieve a decorative effect.
3.
Construction equipment problems: because the water-based colorful paint has certain corrosiveness and adhesion to the coating equipment, especially the iron equipment has a certain rust effect, it is easy to dissolve the metal in the transportation pipeline, cause the dispersed particles to precipitate, and the coating film Pitting occurs; and the dispersion stability of the water-based industrial paint against strong mechanical forces is poor.
4.
Stable effect problem: Because the water content of the water-based colorful paint is high, and the volatilization of water strongly depends on the environment, in a low humidity environment, it may dry quickly and sometimes cause cracks; in a high humidity environment, it becomes The filming process will be very slow and easily cause the paint to sag; in addition, the newly formed paint layer is often very sensitive to water, and the increase of water vapor content in the air will cause the paint to wrinkle.
5.
Storage problem: As the water-based colorful paint is composed of two parts: the dispersed phase and the continuous phase, the two phases are relatively insoluble to form the product of water-based industrial paint.
