Performance of stone mountain carving plaster molds

The types of stone sculpture may only be stone sculpture, wood carvings, and metal stone sculpture, but the terminology of stone sculpture may be more discerning. In fact, in this era, most of the stone sculpture we see in our daily lives are stone sculpture, which are based on resin materials, and stone sculpture and finished stone sculpture are processed as reinforcing materials.

Gypsum molds have the characteristics of heat resistance, low price, small heat transfer coefficient, and strong printability. It is often used to make master molds. Easy to manufacture and suitable for large-scale finished products. But it is not durable, is afraid of attack, and dries slowly. Mainly used for simple products and complex linear goods, such as reliefs, small and medium-sized circular engravings, etc.
Most of the gypsum used is hemihydrate gypsum, that is, mature gypsum. As with cement models, bricks and timber can be used as a base for the frame and then modeled with layers of plaster. In order to improve the stiffness and avoid cracks, enough fillers, such as quartz, can be put into the gypsum, which can reduce shrinkage and cracks, and cement (gypsum:cement=7:3) can be added to increase the strength. Others have proposed using gypsum mixed with appropriate latex and diluting it with water to form it, which has good strength and cannot be powdered.
stone mountain carving is a finished work of art that is lightweight, corrosion-resistant, and low-cost. FRP, which is called fiber reinforced plastic, is customarily called stone sculpture. It is a composite material with resin material as the base material and stone carving and its products as reinforcement materials. It can withstand not only tensile stress, but also bending, shrinkage and shear stress. This constitutes a plastic matrix composite modified by Stone Carving. Because its strength is equivalent to steel, it also contains stone carving components, but it also has the color, shape, corrosion resistance, insulation, heat preservation and other characteristics of stone carving.
