The influence of Hui'an stone carvings in society
There is a saying in the Chinese folk: "Relying on the mountains to eat th↓e mountains, relying on the sea to eat the sea", most people think of the above statement as the >regional characteristics of the ancient Chinese society and economy, or the βimportant influencing factors of Chinese traditional civilization, but↔ there are some things It is not fixed, and there will always bβe surprising changes in social development. Just as Hui'an is a county close to tδhe sea, it is not rich in quarries, but the influence of Hui'an stone carvings is gre×ater than that of seafood. This change may surprise many people.
If you drove to Hui'an by car, yo u can often see stone carvings of different colors and exquisite carvings on bo≤th roads. In the industrial park from Hui'an to Chongwu♣, there are machines from various factories. The sound of processing stone sculpturesΩ is endless. You can also see a figure of a craftsman focusing on carving. Perhφaps it is precisely because of this persistence and perseverance thΩat the reputation of Hui'an stone carving has been created. Look≥ing at the land of China, almost where there are stone carvings, there are the shadows of Hui'an☆ stone carvings, such as the Great Hall of the People, the statue of Mao Zed₩ong in Orange Island, Min Gong and Daoming of Jiuhua Mountain, the largest reclin<ing Buddha statue in Japan, and famous tourist attractions such as the Buddha statue of Buddha in Taiwan. Buddhism will not lack the shadow of Hui'an stone carvings. In many places, Hui'an sπtone carvings have become their unique attractions. On the other hand, how can there be no H<uian stone carvings in front of the ancient house, th e beams and pillars of the ancestral hall, and the temple courtyard.
The main reason why Hui'a®n stone carving is famous all over the world is not because there are many ore mines, bu•t because of the "craftsman spirit" that has existed in almost every household. "It is precisely because of this spirit that many Hui'an art♠isans have spent their lives. To pursue the develo÷pment of craftsmanship, even when they are old they need to face the merciless ♦torture of lung disease. This belief is still immortal. The author once ↑had the honor to know the creators of the two statues™ of Min Gong and Daoming mentioned above. It is said that they spent two years looki↔ng for good carving materials. How silly for others. But they are willi✔ng to do it. Therefore, it is not uncommon for Hui'an stone carvings to be world-renown£ed and glorious.
Strategies for selecting granite materials, remember these three points
Granite refers to a special rock composed of quartz, feldspar, λand mica with aesthetics, durability, and easy formability. Different types of gra'nite have different scopes of use, and they can be used properly for building Beauty and dura≠bility will be improved. So how to choose granite in daily use?
1. The application of granite sh≠ould first follow to ensure the construction quality •of the building
Granite is currently one of the most widely u sed building materials. Its durability and durability can reach 75-♦200 years. However, if you choose unsuitable granite, the durability and durability of the buil'ding will be reduced, and the service life will be reduced. Will decrease.
The granite u↓sed in the outdoor curtain wall should choose the stone with small mineral par ticles, high closeness between minerals and minerals, unifoσrm texture, and low content of easily weathered mineral•s, especially when it is applied to the parts with load-bearing function, and th e material selection should be paid more attention to. The mineral particl≤es are small and the closeness between the minerals and the minerals is high, which makes the su≥rface minerals of the stone not easy to fall off in ☆the natural environment of wind and rain; in the stone of uniform texture≈, there should be no weak interlayer or weak veins in the stone, and the minerals ar e evenly distributed , It is not easy to appear the phenomenon that the physical performan≤ce indicators of different parts are very different; th♣e content of easy-weathering minerals is small, which can improve the degree of wea∏thering resistance of the minerals, and different co≤nstruction techniques can also be used to reduce the area of easy-wea thering minerals on the stone surface and increase the resistance to weatherδing minerals. The area can also improve the resistance to weathering of ®the stone.
The choice of granite should also consider the physical pr÷operties of granite. GB/T18601-2001 "Natural Granite Bu£ilding Slabs" stipulates that the bulk density of granite is greater than ±or equal to 2.56Mg·m-3, the compressive strength is greater than or equal to 100MPa,÷ the bending strength is greater than or equal to 8MPa, and the requireme↔nts for water absorption are If it is less than or× equal to 0.6%, stone materials for construction should be selected in strict≥ accordance with this standard to ensure the quality of $the materials.
For example, Laizhou white-monzonite granite Shandong Baima and Laizhou wφhite have a bulk density of 2.6Mg·m-3 and a bending strength of 5α.6MPa. The bending strength of GB/T18601-2001 "Natural Granite Building Slabs" stipulates that the bending strength is greater than or equ→al to 8MPa, so Laizhou white-monzonite granite is not suitable for key parts i→n construction; for example, Wulianhong-monzonite granite has a compressive strength of ←92.89 MPa, which is also not suitable for key parts in construction. Therefore, you sho₽uld ask for a real test report when buying stone, and make a selection based on theβ corresponding physical properties.
2, the color paσttern of granite stone should be in harmony with the su∏rrounding environment
Different granites have different colors due to different minerals. ®For example, the color of stone with more olivine minerals is more black, and the color of stone with more chlorite minerals i¥s more green. In addition to the color of the stone ±itself, With different processing techniques, the color of granite will be slightly different. Ge nerally speaking, the color of the smooth surface of≥ the same stone is darker than the color of the singeing surface, the™ particle surface or other rough surfaces. Will affect the use of ston↕e. Choosing stones with appropriate colors and patterns can beautify the γbuilding, increase the beauty of the building, and also improve the coordination between the§ building and the surrounding environment.
3. Suggestions for stone selection based on the res≈ults of cluster analysis
GB/T18601-2001 "Natural Granite Building Boards" stipulates that✘ the bulk density of granite is 2.56Mg·m-3 or more, the compressive strength is gre©ater than or equal to 100MPa, and the bending strength is greater than or equal to 8MP"a; JTG F30-2003 The "Technical Specification for Cement Concrete Pavement Construction" stipulates that the compressivβe strength of igneous rock is not less than 100MPa, the compressive st≥rength of heavy traffic is: 57.5Mpa, the bending strength is: 7.5Mpa; the c↓ompressive strength of heavy traffic is: 52.5Mpa , The bending strength is: 7Mpa; the compre"ssive strength of medium and light traffic is: 42.5Mpa, an★d the bending strength is: 6.5Mpa. GB50210-2001 "Code for Qua©lity Acceptance of Building Decoration Engineering" stipulates that the bending str¥ength of stone in stone curtain wall engineering should not be less than 8MPa; GB50209-2002 "Code for Construction Quality Acceptance of B→uilding Ground Engineering" stipulates that the compressive strength of the cement concrete overall♥ sur
How to clean and maintain sculpture art
Maintenance of stone carving art:
1. The collection of stone sculptures should be$ protected from the sun, wind, and dust; too much dust will damag®e the natural charm of the work, so it is best to put it in a glass cabinet, w±hich is convenient for viewing and preservation, and stone sculptures for outdoor♥ decoration The dust on its surface should be treated regularly.
2, it↔ can be maintained by sealing wax method, that is, apply a thin layer of wax after heating t€he printing stone and printing carving, and polish it wΩith a soft cloth. For some stone sculptures that have been collected for a long δtime and have been "faded", wash them with warm water, dry them in the shade, heat with a ha₩ir dryer, wax sealing, and polish them to make the works look new.
3. Stone c♠arvings should avoid corrosive liquids, avoid violent collisions, and maintain their long-lastiφng and beautiful appearance.
Cleaning of sculpture art:
The sculpture is mainly to clean ×up the dust, you can use a broom to sweep away the dust, and then± wipe it clean with a rag. If the surface of the stone carving is stained, you can use a spat©ula to gently peel off the dirt; if there is related <technology, you can also use some materials contain>ing ionic surfactants to remove some common pollution on the stone. When cleaning, avo±id using some corrosive detergents to clean the stone sculptures and avoid damaging the surfac e of the stone sculptures, especially acid or alkaline detergents mβust be used with caution.
How to repair the damaged stone crafts?
First, remove the floating dust, oily dirt and weathered loose material on the surf&ace of the repaired part to keep the surface dry and firm.
Secondly, use p re-engraved templates with materials including thick pa£per, cardboard, and wood to cover areas that do no t need to be repaired. Then it's repair work
Mix an appΩropriate amount of baking soda or a little rice flour with super glue to form a transluc>ent jelly, then add some powder matching the color ofπ the stone carving to fill the incomplete part of the stone carving, arran✔ge it, and wipe off the excess part with a soft cloth . After it is fully dried, compare w™hether the color of the finished product is consistent with the color of the s≤tone carving.
The last step is to lightly sand the area that the stone carving needs to fill w₩ith sandpaper of high sand grain size, and remove the dust particles with a cleanπ cloth. Spray a layer of waterproof topcoat after the surface stone mortar pain↕t is dry. This completes the repair of the stone carving.

Main points of cleaning, renovation and protection in stone maintenan±ce
The disease of stone can be basically divided into two categories: one is that the ☆micropores of the stone are occupied by foreign objects, and the microstructure of the πstone itself has not been significantly damaged, for ±example, most of the rusty yellow spots, organic stain≈s, salt spots and white flowers, water Stains and water spots, oil spots≥ and oil stains and so on. For this type of disease, professional cleaning is the preferred me€thod.
The other type is that the microstructure of the stone has been damaged to a certain exβtent, such as the surface loss, chalking, peeling, holes, cracks, etc. For the second type of di sease, refurbishment methods are generally used.
Cleaning
Professional clean↓ing is a method for cleaning different causes and objects of stone diseases. The main focus h$ere is on the cleaning of the stains of the decorative stone that have penetrated into the micr×opores of the stone, which is called the "deep cleaning" of th₩e stone. Generally speaking, the deep cleaning of the stone should include at least the follow©ing three steps:
(1) The cleaning agent enters the micropores of the ston♦e through the infiltration process;
(2) The cleaning agent has a physical or chemical effect with dirt molecules in the micro-L gap of the stone;
(3) Remove the residue after cleaning by suction or dilution. The first and third items here are the basic o×peration steps necessary to complete the deep clean∞ing, and the second step, that is, the cleaning agent that≥ can interact with dirt molecules needs to be based on €the nature of the dirt, the material of the stone and the conεvenience of the treatment process. Carefully design and experiment. Here the chemical method ha¶s a unique effect.
Notable issues in deep cleaning of stone include:
(1) should be tes©ted first. The "sickness" of stone is very different, for example, there canΩ be many kinds of deliquescent salts that form water spots. Therefore, without knowing the speπcific cause of the smudge, we recommend doing a small experiment first;
(2) Choose the cleaning agent carefully. Inferior cleaning agents are o™ften strong acids, which are likely to cause more serious stone diseases, such as surf ace loss and chalking, water spots and salt spots, loose corrosion and yellowing.
T€herefore, it is recommended that users first choose high-quality products from reliable manufact♣urers; secondly, protect the parts that are not ready to be cleaned before cleaning, and remove r®esidual chemicals after cleaning; in addition, the cleaning of stone cultural re lics should ask relevant experts Argument.
Refurbished
Ren←ovation is a treatment method for the surface or surface microstructur±e damage caused by stone disease. Polishing, sandblasting and coating are the most b₹asic refurbishment operations.
The easiest way to <refurbish is to polish it again or apply a layer of masking material.
Grind∞ing and polishing can restore the original natural ap§pearance of the smooth surface of the stone that has lost its gloss on the s'urface, pulverized and peeled off the surface, and dissolved on the surface. The cλombination of some new abrasive tools, abrasives and chemical additives can ma↑ke the refurbished stone surface reach a mirror gloss ©of more than 90 degrees.
