Color and coloring are a key issue. Cultural stones are not uniform in color. This is usually done. Light brown first, then gray. After the light gray is adjusted, these three different colors are sprayed inside the mold.
Instead of spraying it all at once, divide the mold into several different areas, spray these colors, and finally pour cement into the mold. Of course, not all three colors can be modulated freely.
Yes, the key is to spray the color into the mold before pouring the cement. Use a separate spray gun for each color, and spray different colors in different areas, which will make the colors not single, but one.
Natural surplus.
Quyang natural culture stone combined with many years of practical experience, the color of artificial cultural stone is incorrect mainly for the following reasons:
1. Pigment: Too much color difference. Generally speaking, the color of artificial cultural stone is divided into two parts: front and background.
The color must use good quality pigments, and the background color is unnecessary to consider. Moreover, each color of pigment has a different model. Once you decide, don't change the color model casually.
2. Cement: Yes.
In order to reduce the cost, people use black cement to make artificial cultural stone, which is not good, because the black water mud has high alkali content and is easy to pan-alkali and white, and the color of black cement itself is difficult to match the color of the model.
3. Mold: Some factories use resin molds to reduce costs, but the resin molds themselves are not easy to color, which affects the color coloring. It is suggested that you use silicone rubber as an artificial cultural stone mold.
Although the cost may be high, the products made are exquisite and realistic, pure in color and will not be showy. And its comprehensive cost is not much higher than that of resin mold.
Artificial cultural stone is one of the color products.
Large defects, to measure the quality of artificial cultural stone, whether it fades or not is the most critical standard. Then, how can the artificial cultural stone not fade? In the case of using the same raw materials, fixative is used.
It can greatly enhance the color fastness of artificial stone, and can ensure that the artificial stone product does not fade after demoulding. However, the amount of fixing agent should be strictly controlled in the process of use, and excessive use will cause labor.
Cultural stone bubbles, and if it is used less, it will not play a role in fixing color. The specific dosage should be determined by experiments according to local natural conditions (because the dosage of fixing agent should be determined according to local climate conditions and mold materials)
