How to control the size of water color spots?
Observe the size of the color particles. If the size of the color particles is too small, re production is required. The size of the water color particles in the water bag depends on the speed of mixing and dispersing when the color particles are formed. Set the rotation speed according to the specific color requirements. Observe and adjust the shape of the color particles by following the method of high frequency and many times. If the shape of the spraying point is small, the pressure of the spray gun can be increased properly to spray again.
No.2
How did the water in the water spray?
Remove the spray area to the putty layer, and spray again after cleaning. Pay attention to protect other completed areas to avoid secondary pollution.
No.3
Why is water in water unsuitable for storage?
Water in water is a kind of material which is dispersed in emulsion medium but not blended with water latex particles. No matter the coating type or reactive type, due to the volatilization of coating components, the fusion of color particles is only a matter of time. The high-quality water in bag aquatic products can be preserved for more than 10 days, while the low-quality products will be layered and moldy less than a week.
No.4
In the preparation of water in water multicolor coating, what should be done if the particles are too soft?
The content of powder can be increased according to the actual situation. At present, a more effective method is to choose emulsion with higher glazed temperature, which can improve particle hardness. Secondly, other additives can be added, such as a small amount of silica sol. The specific effect needs to be tested according to the actual situation.
No.5
What is the low water emulsion of water in water multicolor coating?
If the amount of emulsion is low, the performance of products such as color retention, UV resistance and adhesion will be reduced. Otherwise, if the emulsion is too large, the wall will not dry easily after painting.
No.6
What is the cause of water in water joint seal?
This may be due to the uneven spraying of water in water coating or the uneven treatment of the base surface. At present, the effective solution is block construction.
No.7
How to solve the thick crack of water in water spray?
The water in water multicolour paint is made of emulsion and color paste. After the film is formed, the elasticity coefficient is very high. The higher the thickness is, the better the crack resistance is.
No.8
Can water in water multicolor coating be used without finishing coat?
The water in the water multicolor coating is in the outdoor complex environment, which can play a good role in protecting the main coating, with UV resistance, increasing adhesion, improving weather resistance, yellowing resistance and so on. It is recommended to use the water in the water special finishing coat.
