Jade carving, commonly known as jade ware, has a long history. Jade pendants appeared in China during the Neolithic Period, and the jade carving skills of the Shang Dynasty were relatively mature. There are dozens of jade carving materials, such as white jade, jasper, sapphire, black jade, jadeite, crystal, agate, topaz, single jade, Xiuyu, etc. God of Literature Sculpture Because the jade itself is fine, hard and warm, or white as cream, or green and green, bright and lovely color, suitable for making valuable decorations. As for the production of jade, most people think it is carved with a carving knife, but it is not. Sculpture manufactor The jade is hard, and the carving knife cannot cut it into it. Instead, it is polished by various shapes of drill bits, emery and water, depending on the shape of the work. Therefore, it takes a long time to complete a jade carving.

Marble, granite, Hui'an stone, Qingtian stone, Shoushan stone, Guicui stone and other materials are generally used for stone carving. Granite and marble are suitable for carving large statues; Qingtian stone and Shoushan stone are rich in color, which are more suitable for small stone carvings. There are many ways to make stone carvings. According to the nature of stone materials and the habits of the carvers, stone carvings can be roughly divided into two types: first, traditional methods. Conception, composition, modeling and stone carving are all done by individuals alone. For large-scale carving of lines, the horizontal and vertical lines shall be drawn on the stone, the grid shall be made to take materials, and the simple measurement and positioning method shall be used for carving. The second is to adopt a new process, that is, first make a clay sculpture, turn it into a plaster statue, then take the plaster statue (model) as the basis, rely on the point shaped instrument, and then carve it into a stone statue.

At present, most of the most influential sculptures in China and the West are made of copper. For example, Rodin's "The Thinker", "The Bronze Age", and "The Statue of Liberty", the world's top sculptures are mostly made of copper. The lines are suitable for sculpture because of the texture, plasticity, unlimited specifications, and rich color texture of copper, which are also jade sculptures The effect that wood carving and stone carving can't achieve is that jade carving can only make very small works because of the limitation of materials. Because of the limitation of wood carving technology, there is no precedent for large outdoor sculptures. The inheritor, whose bronze carving has opened a new chapter in the 5000 year history of copper.

GRC components can be widely used in the internal partitions of offices, business and residential buildings, corridors and kitchens. The production process, installation and operation are simple and easy to master; The market prospect is broad and suitable for investors and entrepreneurs to explore and develop. However, the outstanding problems of ordinary magnesium partition board are: poor water resistance, easy moisture absorption and halogen return on the surface, and high water content. According to long-term research, development and production experience, Hainan EPS has fundamentally improved the physical and mechanical properties and water resistance of modified magnesium lightweight composite insulation board through reasonable production process and advanced and unique modification technology. This product has low cost, high strength Long service life, excellent heat and sound insulation effect, light weight per unit volume, etc., and no need to soak in water for curing after modification. It is mainly used for building wall insulation (such as reinforced concrete wall, ceramsite hollow block infilled wall, concrete hollow block wall, clay porous brick wall, etc.), building roof insulation system, steel plate roof insulation, ground insulation, warehouse insulation, pavement foundation, and can be widely used in many fields, such as refrigerator cars, square floors, airports, etc.
