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.

Later, some people carved ancient poems on the four sides of the square pillar of the seal with very fine words. In the 1960s, with the application of advanced scientific instruments such as magnifiers in the field of micro sculpture, micro sculpture art became a new and unique art. The words carved in the works are smaller and smaller, and the content is more and more. Microcarvings pay special attention to the selection of materials. The texture of the Hainan EPS component stone is required to be absolutely pure, and there should be no sand grid and half silk cracks, because half of the sand dot may be engraved with more than 10 Chinese characters.

The more subtle it is, the more refined its kungfu is, and the higher its value is. Sculpture customization customized Microcarving is also an art that pays great attention to the picture and organization, which is "intended to be refined". The sculptor of micro sculpture must first have a deep knowledge of calligraphy and painting. Although the micro sculpture is too small to be recognized with the naked eye, it is still very exquisite under the magnifying glass, such as large calligraphy works.

Exterior wall decorative panel is a new type of integrated material for building exterior wall decoration and insulation developed in recent years, which is composed of polyester baking paint or fluorocarbon paint, carved aluminum zinc alloy steel plate, polyurethane insulation layer and glass fiber cloth; It is mainly used for exterior wall decoration and energy-saving reconstruction of gymnasiums, libraries, school and hospital office buildings, villas and other buildings; The main functions are building decoration, heat preservation, energy conservation, heat insulation, sound insulation, waterproof and mildew proof. The metal surface decorative insulation board is a large format external wall board produced in industrialization. It has good durability and low maintenance cost due to dry installation construction. It integrates the external wall insulation and decoration functions, conforms to the development direction of building energy conservation "modularization" technology, and is an advanced technology vigorously promoted in the field of external temperature protection technology of building walls in China.
