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.

The art of carving various patterns and images on stones, usually also refers to sculpture handicrafts carved from stones. Chinese stone carving can be divided into bluestone carving, marble carving, white marble carving, talc carving, black crystal stone carving, colored stone carving, pebble carving, etc. Hui'an, Fujian, is famous for its bluestone carvings for architectural decoration and stone lions, among which the mouth of the stone lion contains stone beads that roll freely, and is famous in Southeast Asia. The marble carving in Yunnan is made from the marble of Diancang Mountain. Its patterns are like colored mountains and rivers, or dangerous peaks and valleys, or waterfalls follow the clouds. The inlaid furniture is unique. White marble carvings in Quyang, Hebei, Fangshan, Beijing and other places were mainly used for palace architectural decoration in the Ming and Qing dynasties, such as Huabiao, stone lions, railings, etc; Modern times are used for decoration of public and memorial buildings, such as the Great Hall of the People, the Monument to the People's Heroes, Chairman Mao's Memorial Hall, etc. Talc carvings in Haicheng, Liaoning Province and Laizhou, Shandong Province use small and cute animals as traditional varieties. The carvings of black crystal stone in Dongkou, Hunan and Lichuan, Hubei are dark and bright. Caishi carving is mainly produced in Qingtian, Zhejiang, Shoushan, Fuzhou, and Liuyang, Hunan. Pebble carvings are mainly produced in Lanzhou, Shenyang and other places. Stone carving techniques include intaglio (contour carving), shadow carving, relief, round carving (complete three-dimensional carving without any background), and openwork (also known as openwork). Shadow carving is a unique technique of Fujian Hui'an bluestone carving. It uses steel drills of different sizes to chisel on the bluestone, and uses the size, depth and density of the drill points to express the images of landscapes, birds, animals, people, flowers, etc.

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.

Auxiliary tools for wood carving: mainly hammer, wood file, axe and saw. The purpose of the axe is to cut a large amount of wood with the help of paring. Pay attention not to use too much force when cutting. Do not cut straight up and down. The edge of the axe should be kept at about 45 degrees with the vertical wood grain, otherwise the wood will crack. Hainan GRC component wood file is mainly used in the fine blank stage of round carving, which can replace the flat knife to smooth the chisel marks for polishing; It can also take the place of round knife or oblique knife for hollowing. The function of the wood file is also that it can quickly adjust the modeling structure in a large area, and can be used in combination with the carving knife to make the turning and turning of the figure's clothing patterns vivid and smooth, with both virtual and real effects. The shape of hammers for wooden sculptures in Hainan is flat, flat, wide and square. The dimension of hammer face can be controlled at about 7 × 5.5 × 2.5 cm. Too narrow or too thick will affect the accuracy of the hammer's landing point and the uniformity of force. There are two kinds of hammers: wooden hammers and iron hammers. The wooden hammers generally use hardwoods with a large proportion of wood, such as mahogany, boxwood, sandalwood, beech and fruit trees. The specifications can be controlled at 27 cm in length, 55 cm in width and 45 cm in thickness; The grip is round and slightly flat, and the size is suitable for holding in the hand.
