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.

Micro carving is a kind of carving technique that is good at small and fine. Chinese micro sculpture has a long history. Miniature carvings appeared in oracle bone inscriptions as far back as the Shang Dynasty. During the Warring States Period, the seal was as small as millet, but the seal was divided into white and black. Wang Shuyuan's Nuclear Boat Story, which is widely known, is also a classic work of micro sculpture in Chinese history. The art of seal cutting is the basis for the emergence and development of micro carving art. Since the Ming and Qing Dynasties, many literati and scholars have used iron pen to write and paint in the seal, to express their interest and entertain themselves. After Shoushan Stone became the seal material, the micro carving art of Shoushan Stone began to appear. At the beginning of the Qing Dynasty, Yang Xuan and Diaobin both carved small characters in the remote patterns of Shoushan stone carvings. Lin Qingqing, a master of "Ximen Boyi School" carving, also often wrote his name and date of production in the grass and stone crevices of the carved works with extremely fine pen. Later, some people carved ancient poems with extremely fine characters on the four sides of the square pillars of the seal as margin. 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. Secondly, the micro carving knife is also a special thin knife, which should be sharp and sharp. Third, it is necessary to have a particularly proficient knowledge of calligraphy and traditional Chinese painting. When carving, you can carry out "free engraving". Fourth, hold your breath and concentrate on your thoughts on the spot. Fifth, the knife should be handled steadily, accurately and ruthlessly. Only in this way can calligraphy and knife technique be perfectly unified. The art of micro sculpture is "art in micro". The more subtle it is, the more refined its kungfu is, and the higher its value is. 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 should 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.

First of all, make the structural layer of the steel bar mountain mesh on the stone wall. According to the Hainan sculpture stone structure, the density of the steel bar is about 30 to 50 cm. Then, bind and weld the steel bar on the exposed steel bar head. Pay attention to the need to shape the approximate shape. After the steel bar is welded, tie a layer of steel wire mesh outside, and then start painting. The first painting is to make a base layer. For the second painting and shaping, it is necessary to make some rock texture, such as concave and convex, wrinkles, because the above steps must be grasped, and craftsmen must make the surface very artistic! Must have basic skills of modeling and stone molding. It is effective to spray stone like paint. Before large-area spraying, small samples were tested to show speckled particles in natural stone. Fill the gaps in the stone wall with earth and then plant them. Maybe fill some ceramic bottles and jars that are harmonious with the theme materials. There are still some water sources in the pottery to supplement its spatial diversity. There is also a new type of plastic stone, which is made of light materials such as environment-friendly building raw materials, fine resins, efficient reinforcing agents, pro aggregate, imported pigments, etc., by mixing, processing, molding, and then steaming at high temperature. Each product has different shapes and various combinations, which are no different from real stones in texture, color and texture.

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", the world's top sculptures are mostly made of copper. The lines are suitable for sculpture because of the texture, plasticity, unlimited specifications, and rich color texture of copper, which are also jade sculptures The effect that wood carving and stone carving can't achieve is that jade carving can only make very small works because of the limitation of materials. Because of the limitation of wood carving technology, there is no precedent for large outdoor sculptures. The inheritor, whose bronze carving has opened a new chapter in the 5000 year history of copper.

Most of the jades mentioned in daily life refer to nephrite, and there are many kinds of nephrite products. Generally, they refer to white sheepskin jade, white jade, topaz, purple jade, black jade, jasper, sapphire, ruby and northeast Xiuyu produced in Xinjiang. high quality Colored sculpture In the jade carving, the white jade with sheepskin is fine in texture and strong in luster, as white as sheepskin, which can be called "the king of nephrite" and "the crown of white jade". In addition, Nanyang jade, Lantian jade, Hotan jade, agate, crystal, coral, turquoise, lapis lazuli, etc., all belong to the category of nephrite. Later, due to the opening of the Silk Road, the jade produced in Hotan, Xinjiang, was unanimously recognized and began to play a leading role in the processing of royal, official and folk jade. Colored sculpture customized Nephrite gradually evolved into a synonym for hotan jade.

The types of stone inscription monuments include monuments, memorial monuments, merit monuments, temple monuments, Dianzi monuments, mausoleum monuments, etc. Except for a few wordless steles, they are generally literal steles. Usually, characters are carved on the body of the stele, and some are accompanied by carved patterns. The pedestal and cover of the stele are mostly carved with decorations, birds, animals, flowers, and mascots. The cover of the stele of the imperial family is also carved with dragons and phoenixes. Marble is the most commonly used stone for making the stele, and sandstone and granite are also commonly used. Some of the steles are huge, and some of them become a group of steles. Stone books are written with stone instead of paper, and carved instead of pen, which is very ingenious. There are many famous works of stone tablet processing and stone calligraphy carving. For example, "Xi'an Forest of Steles" includes more than 3000 historical steles from Han Dynasty to Qing Dynasty. It is the largest collection of stone books in China. Together with the "Forest of Steles in Hanlin" under construction in Kaifeng, it can be said that it is a sea of steles, and it is a collection of calligraphies of regular script, line, grass, seal script, clerical script and Wei style by famous calligraphers of all ages. In addition to large-scale carvings such as stele books and cliff carvings, there are also some stone carvings, such as mourning volumes in imperial tombs and modern fine carved small stone books, such as more than 100 mourning volumes of white marble excavated in the tomb of the prince of the Tang Dynasty, and six stone books of "Thirty six Strategies" carved in tile slate in modern Chengdu, a total of 26 pages and 1278 words, bound into a volume with eyeliner, each page is 2.2.6mm, which can be read.
