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 external hanging 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.

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.

EPS decorative line is a new type of exterior wall decorative line and component, which is more suitable for installation. On the walls with EPS and XPS insulation of exterior walls, it can not only reflect the European classical and elegant decorative style, but it is very difficult to install cement components, with a long construction period, cracks will appear over time, and poor durability. However, using EPS decorative line has the advantages of convenient installation, economy, and long durability. With the continuous development of the building decoration industry, more and more new materials have come to the fore, which are favored by more and more people. More and more enterprises have entered the EPS line, and some professional companies have come to the fore. Not affected by temperature change, cold resistant and heat resistant; Not affected by humid climate and acid rain. EPS decorative lines can prevent fire without emitting toxic substances, and are environmental friendly high-quality decorative building materials. EPS decorative lines are cut by computer numerical control, which is fast in production and has many varieties and models, such as lines, Roman columns, window covers, brackets, etc., and can be installed on the four sides of windows, door edges, eaves corners and wall bodies; Make the facade of the building more beautiful, and bring new and different ideas to the architects.

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). It can be divided into light relief and high relief according to the depth of stone removal in image modeling. 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.

Decoration materials are divided into two parts: one is outdoor materials, the other is indoor materials. Indoor materials are divided into five types: solid materials, plates, sheets, profiles, and wires. The real material is also the raw material, which refers to logs and logs. The commonly used logs are Chinese fir, red pine, elm, ash, camphor, basswood, and the more valuable ones are rosewood, beech, oak, etc. The timbers used in decoration are mainly made of fir, and other timbers are mainly used for supporting furniture and carved accessories. The technique of artistic processing of articles for daily use or living environment. It must be organically combined with the decorated object to become a unified and harmonious whole, so as to enrich the artistic image, expand the artistic expression, strengthen the aesthetic effect, and improve its function, economic value and social benefits.
