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.

Copper casting is an important part of Chinese traditional culture and art. Hangzhou Abstract sculpture Copper casting has a long history and mature technology. The process of casting copper is more complicated than that of forging copper, and the artistic creation has a good recovery. Therefore, it is suitable for becoming the material of fine works and is very popular with artists, especially figure sculpture. But it is easy to oxidize, so pay more attention to maintenance. Each cast copper artwork is made through 11 complex and rigorous processes, which have traces of traditional handicrafts, recommend Abstract sculpture The lines also have the modern technology of precision casting. Cast copper is put into the sintering furnace and sintered at 1000 ℃ - 1150 ℃ according to different metal materials. The copper liquid is immediately cast into the ceramic shell. After cooling, the outer ceramic shell is broken, and the copper product rough embryo is peeled out.

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.

Full name of GRC component: GRC building detail decoration component. Abbreviation of the specification: GRC building details. Because the name of GRC building detail decoration component is too long to remember, lines are often referred to as GRC components. Because of the prevalence of European customs in recent years, they are also often called GRC European components, GRC Roman columns, GRC eaves lines, GRC decorative lines, GRC corner lines, GRC door and window covers, GRC vase railings, etc. According to the national standard Code for Acceptance of Construction Quality of Building Decoration Engineering (GB50210-2001) issued by the Ministry of Construction, GRC building detail decoration component belongs to one of the building components in the detail project of building decoration engineering. The product is to mix the raw materials according to a certain proportion, and Hainan sculpture is poured into the mold, which can produce products with rich shapes and diverse textures. According to the different needs of customers and designers, we can carry out arbitrary art modeling to perfectly realize the designer's design dream.

Root carving is to create artistic works of characters, animals, utensils and other artistic images through conception, artistic processing and process, taking the autogenetic form and distorted form of tree roots (including tree bodies, nodules, bamboo roots, etc.) as the object of artistic creation. Root carving art is a kind of plastic art that finds natural beauty and shows creative processing. The so-called "three parts of labor, seven parts of nature" means that in the creation of root carving, most of the natural forms of root materials should be used to express artistic images, and a few of them should be artificially processed and modified. Therefore, root carving is also called "root art" or "root art". The basic technique of root carving is to use exaggeration, fantasy and abstraction to reflect real life. To be specific, it is to make a comprehensive and careful observation of the selected root material and make a clever idea. By virtue of its shape, texture, knots, concavity and convexity, curvature, holes, and so on, it is a bold idea to combine the virtual with the real. The line seeks the usable value of the material itself with a variety of themes and contents, and is good at finding the extraordinary from the ordinary, and gradually determines the overall image of the creation. It is very important to make clear the creative idea and imagine boldly for the root generation creation.

Microcarvings pay special attention to the selection of materials. The stone material should be absolutely pure, and there should be no sand grid or half silk cracks, because half a sand dot may damage a fine picture or more than 10 Chinese characters. Secondly, the micro carving knife is also a special thin knife, which should be sharp and sharp. It is necessary to have a particularly proficient knowledge of calligraphy and traditional Chinese painting. When carving, "meaning carving" and "meaning carving" can be carried out. Hold your breath and concentrate on your thoughts on the spot. The knife should be stable, accurate and ruthless. The micro carved knife is just a pen. The skill is not enough. Because the knife is slightly out of control, it doesn't reach its purpose. The calligraphy effect must be paid attention to when matching the micro engraving inscriptions on the micro sculpture works. The creators should avoid the ugly appearance, the skew of characters, the uneven lines, the inaccuracy of paintings, and the imbalance of matching. We should grasp the artistic effect of the line changes produced by cutting tools and customized stones. Only in this way can calligraphy and knife techniques and strokes be perfectly unified.
