Cultural stones generally use silica gel molds. First, the color should be adjusted with colored soil. The color of cultural stones and cultural bricks should be adjusted according to the specific situation. There are basically more than a dozen colors of colored soil, and different colors can be mixed to achieve the color you need. Coloring is a key issue. The color of cultural stones is not uniform. Generally, it is done in this way. First, light brown, then gray, and then light gray, spray these three different colors on the inside the mold,
Instead of spraying all the parts, divide the interior of the mold into several different areas, spray these colors, and finally pour cement into the mold. Of course, not all of these three colors, the colors can be freely adjusted , the key is to spray the color into the mold before it is poured into the cement. Each color must be sprayed with a separate spray gun, and different colors are sprayed in different areas, which will make the color not single. A natural excess.
Based on years of practical experience of LYA Group, the main reasons for the incorrect color of artificial cultural stones are as follows:
1. Pigment: The color deviation is too large. Generally speaking, the color of artificial cultural stone is divided into two parts: face color and base color.
The color must use good quality pigments, but the background color does not need to be considered in this way. And there are different models for each color of the face paint, once it is fixed, you should not change the model of the color used casually.
2. Cement:
In order to reduce costs, some people use black cement to make artificial cultural stones. This is not good, because black cement has a high alkali content and is prone to pan-alkali and whitening. In addition, black cement is difficult to match the model because of its own color. s color.
3. Mold: Some factories use resin molds in order to reduce costs, and resin molds are not easy to color, which affects the color of the color. It is recommended that you use silicone rubber to make artificial cultural stone molds, although the cost may be high. point, but the products made are delicate and lifelike, and the colors are pure and will not fade. Furthermore, the comprehensive cost of silicone rubber cultural stone molds is not much higher than that of resin molds.
The loss of color of artificial cultural stone is a major defect of the product. To measure the quality of artificial cultural stone, whether it loses color is the most critical criterion for judging it. So, how can the artificial cultural stone not lose its color? In the case of using the same raw materials, the use of color-fixing agents can greatly enhance the color firmness of artificial cultural stones, so that the cultural stone products will not lose their color as soon as they are released from the mold. However, the amount of color fixing agent should be strictly controlled in the process of use. If it is used too much, it will cause foaming of the artificial culture stone, and if it is used too little, it will not be able to fix the color. The specific usage amount should be tested according to the natural conditions of each place to determine the optimal usage amount (because the amount of color fixing agent should be based on the local climate conditions and the material of the mold
