Sometimes in order to achieve the effect of production, people usually use a certain material to increase the strength of the finished product, for example:
1. The gypsum powder is mixed with the resin and the curing agent into a paste, so that the finished product is greatly improved in strength compared with the ordinary finished product.
2. The gypsum finished product is reinforced with one or more materials such as glass cloth, gauze, and resin.
3, sometimes milk white glue is also a major excipient in gypsum production. Gypsum added with milky white glue, the finished product will be smoother and more delicate than ordinary gypsum, but the oil will float on the surface of the object when it is colored, so it will not be absorbed by the gypsum, so pay more attention!
