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.

Relief is a kind of sculpture. The sculptor carves the image he wants to shape on a flat plate, making it separate from the plane of the original material. Relief is the product of the combination of sculpture and painting. It deals with objects in a compressed way, and displays three-dimensional space by perspective and other factors. It is only for one side or two sides to see. The reliefs are usually attached to another plane, so they are used more in architecture and can be seen on utensils and implements. Due to its compression characteristics, it occupies less space, so it is suitable for decoration in a variety of environments. In recent years, it has played an increasingly important role in urban beautification. The relief is as rich and colorful as the round sculpture in content, form and material. The materials of relief include stone, wood, ivory and metal. The relief is a semi vertical sculpture whose image shape protrudes from the stone surface (as opposed to the relief). According to the different depth of stone removal in image modeling, it can be divided into low relief and high relief. The bas reliefs are single level statues with relatively simple contents; The high relief is a multi-level statue with complicated contents. The carving technique and expression style of relief are basically the same as those of round sculpture. Many ancient and modern large-scale memorial buildings, high-end mansions and private houses are equipped with such decorations. Their main works are wall blocks, flower windows, dragon columns (early) and column bases.

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 are all made of copper, Guangxi Colored sculpture The lines are suitable for sculpture because of the texture, plasticity, unlimited specifications, rich color texture and other reasons of the copper material, which is also an effect that jade, wood and stone carvings cannot achieve. Jade carvings can only do very small works because of the material restrictions, high quality Colored sculpture Due to the limitations of wood carving technology, there is no precedent for large-scale outdoor sculptures. The inheritor, whose bronze sculptures opened a new chapter in the 5000 year history of copper.

Shallow relief has a low rise, a large compression of shape, a strong sense of plane, and is closer to the form of painting to a greater extent. It does not rely mainly on physical space to create space effects, but uses more painting techniques or perspective, illusion and other processing methods to create more abstract compression space, which is conducive to strengthening the dependency of relief suitable for the carrier. The ancient Assyrians of Mesopotamia were probably the artists who were best at performing art by this means. In a series of "Assyrian Hunting Pictures", they used the technique of bas relief very well to express the lively artistic image with a sense of rhythm and rhythm, and to show the inner feelings of the characters and animals with complex dynamics. The selection of the compression degree of relief space usually takes into account the function, theme, environmental location, light and other factors of the performance object, of which the environment and light factors play a decisive role. Excellent sculptors can always handle these relationships well, so that the works can achieve good visual effects.
