The influence of Hui'an stone carvings in society
There is a saying in the Chinese folk: "Relying on the mountai≈ns to eat the mountains, relying on the sea to eat the sea", most people think of the ↔above statement as the regional characteristics of the ancie₹nt Chinese society and economy, or the important influencing factor♠s of Chinese traditional civilization, but there are some ↓things It is not fixed, and there will always be surprising chang£es in social development. Just as Hui'an is a county close to t↓he sea, it is not rich in quarries, but the influence₩ of Hui'an stone carvings is greater than that of seafood. This change maγy surprise many people.
If you drove to Hui'an by car, you can often see stonλe carvings of different colors and exquisite carvings on both roads↕. In the industrial park from Hui'an to Chongwu, there are machines from ∞various factories. The sound of processing stone sculptures is endless.₽ You can also see a figure of a craftsman focusing on carving. Perhaps it is precisely₽ because of this persistence and perseverance that the reputation of Hui'an stoαne carving has been created. Looking at the land of China, almost where there are stone carvin∞gs, there are the shadows of Hui'an stone carvings, such as the Gr↕eat Hall of the People, the statue of Mao Zedong in Orange Island, Min ®Gong and Daoming of Jiuhua Mountain, the largest reclining 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 st♠one carvings have become their unique attractions. On the other hand, how can there b₹e no Huian stone carvings in front of the ancient house, ¥the beams and pillars of the ancestral hall, and the temple courtyard.
The main reason why₹ Hui'an stone carving is famous all over the world is nεot because there are many ore mines, but because of the "craftsman spirit" that has existed in almost every h☆ousehold. It is precisely because of this spirit that many Hui'an artisans∑ have spent their lives. To pursue the development •of craftsmanship, even when they are old they need to face thπe merciless torture of lung disease. This belief is still immortal. The author onc♠e 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 looking for good carvδing materials. How silly for others. But they are w∏illing to do it. Therefore, it is not uncommon for Hui'an sto♣ne carvings to be world-renowned and glorious.
Strategies for selecting granite materials, remember these three points
Granite refers to a special rock composed of quartz, feldspar, and mica with aesthetics, durabilit©y, and easy formability. Different types of granite have different sc'opes of use, and they can be used properly for building Beauty and durability w¥ill be improved. So how to choose granite in daily use?
1. The σapplication of granite should first follow to ensure the construction quality of th↔e building
Granite is currently one of the most widely used building₩ materials. Its durability and durability can reach 75-200 Ωyears. However, if you choose unsuitable granite, the ×durability and durability of the building will be reduce♦d, and the service life will be reduced. Will decrease.
The granite used ∏in the outdoor curtain wall should choose the stone with small mineral particles , high closeness between minerals and minerals, uniform texture, and low content₩ of easily weathered minerals, especially when it is applied to t he parts with load-bearing function, and the material sel§ection should be paid more attention to. The miner♠al particles are small and the closeness between the minerals λand the minerals is high, which makes the surface 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 ¶are evenly distributed , It is not easy to appear the phenomenon that the physical performance indicators of different parts are very differ≤ent; the content of easy-weathering minerals is small, which can improve the degree of wea©thering resistance of the minerals, and different construction techni↓ques can also be used to reduce the area of easy-weathering mineral£s on the stone surface and increase the resistance to weathering minerals. The area can also $improve the resistance to weathering of the stone.
The choice of granite should also consider t♣he physical properties of granite. GB/T18601-2001 "Natural Granite Building Slabs" stipulates ↔that the bulk density of granite is greater than or equal to 2.56Mg·m-3, the compressive γstrength is greater than or equal to 100MPa, the bending strength is great♦er than or equal to 8MPa, and the requirements for water absorption are If it is less th£an or equal to 0.6%, stone materials for construction shoul•d be selected in strict accordance with this standard to ensure the quality of the materiaβls.
For example, Laizhou white-monzonite granite Shandong Baima and La←izhou white have a bulk density of 2.6Mg·m-3 and a bending strength of 5.6MPa. The be®nding strength of GB/T18601-2001 "Natural Granite Building Slab¶s" stipulates that the bending strength is greater than or equal to 8MPa, so Laizh♦ou white-monzonite granite is not suitable for key parts in construction; for example, W ulianhong-monzonite granite has a compressive strength of 92.89 MPa, which is also not suitable fo©r key parts in construction. Therefore, you should ask for a real test ≤report when buying stone, and make a selection bas↔ed on the corresponding physical properties.
2, the color pattern of granite stone should λbe in harmony with the surrounding environment
Different grani↕tes 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 is more green. I&n addition to the color of the stone itself, With different proceΩssing techniques, the color of granite will be slightly different. Generπally speaking, the color of the smooth surface of the same stone is dΩarker than the color of the singeing surface, the part±icle surface or other rough surfaces. Will affect the use of stone. Choosing stones w©ith appropriate colors and patterns can beautify the building, increase the beauty λof the building, and also improve the coordination between the building and the surrounding environment.
3. Suggestions for stone selection based onβ the results of cluster analysis
GB/T18601-2001 "Natural Granite Building Boards" s♣tipulates that the bulk density of granite is 2.56Mg·m-3 or↔ more, the compressive strength is greater than or equal to 100MPa, and the bending sαtrength is greater than or equal to 8MPa; JTG F30-2003 The "Techn♥ical Specification for Cement Concrete Pavement Construction" stipulates that the compressive stre®ngth of igneous rock is not less than 100MPa, the compressive strength of h₽eavy traffic is: 57.5Mpa, the bending strength is: 7.5Mpa; the compressive strength of heavy tra™ffic is: 52.5Mpa , The bending strength is: 7Mpa; the compressive strength of medium ™and light traffic is: 42.5Mpa, and the bending strength is: 6.5Mpa. GB50210-2001 "Coβde for Quality Acceptance of Building Decoration Engineering" stipulates that the bending ₽strength of stone in stone curtain wall engineering should not be less than 8MPa; GB5φ0209-2002 "Code for Construction Quality Acceptance of Building Ground Engineeri★ng" stipulates that the compressive strength of the cem≥ent concrete overall sur
How to clean and maintain sculpture art
Maintenance of stone carving art:
1. The collection of stone sculptures should be pro∑tected from the sun, wind, and dust; too much dust will damage the natural charm of ≥the work, so it is best to put it in a glass cabin>et, which is convenient for viewing and preservation, a nd stone sculptures for outdoor decoration The dust on its surfac←e should be treated regularly.
2, it can be maintained by sealing wax metho≠d, that is, apply a thin layer of wax after heating the printing stone and printing carving, and polish it with a soft cloth. For some stone sculptures that ha↕ve been collected for a long time and have been "faded", wash them with war∏m water, dry them in the shade, heat with a hair dryer, wax sealing, ∞and polish them to make the works look new.
3. Stone carvings should avoid corrosive liquids, avoid violent collisions, and ma↔intain their long-lasting and beautiful appearanceφ.
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 w•ith a rag. If the surface of the stone carving is stained, you can♦ use a spatula to gently peel off the dirt; if there is γrelated technology, you can also use some materials containing ionic♠ surfactants to remove some common pollution on the stone. When cleaning, avoid using ₹some corrosive detergents to clean the stone sculptures↕ and avoid damaging the surface of the stone sculp÷tures, especially acid or alkaline detergents must be used with cautio n.
How to repair the damaged stone crafts?
First, remove the floating dust, oily dirt and weathered loose material on the₽ surface of the repaired part to keep the surface πdry and firm.
Secondly, use pre-engraved templates with materials including thick paper, cardboard, and wood to cover areas that do not need to be repair≥ed. Then it's repair work
Mix an appropriate amount of< baking soda or a little rice flour with super glue to form a translucent je•lly, then add some powder matching the color of the stone carving to fill the incomσplete part of the stone carving, arrange it, and wipe off the excess part with a so™ft cloth . After it is fully dried, compare whether the color of≥ the finished product is consistent with the color of the stone car®ving.
The last step is to lightly sand the area that the stone carving needs to fill with san₩dpaper of high sand grain size, and remove the dust particles with a clean cloth. Spray a layer of™ waterproof topcoat after the surface stone mortar paint is dry. This comαpletes the repair of the stone carving.

Main points of cleaning, renovation and protection in stone maintenance
The disease of stone can be basically divided into two categories: one is that the micΩropores of the stone are occupied by foreign objects, and theδ microstructure of the stone itself has not been significantly dam↓aged, for example, most of the rusty yellow spots, org≤anic stains, salt spots and white flowers, water Stains and water spots, oil spots and oil stains εand so on. For this type of disease, professional cleaning is the preferre≤d method.
The other type is that the microstructure of the stone has been >damaged to a certain extent, such as the surface loss, chalking, peeling, holes, cracks, etc. For the second type of disease, refurbishment m≥ethods are generally used.
Cleaning
Professional cleaning is a method for cleaning€ different causes and objects of stone diseases. The main focus here is on the cleaning of ≈the stains of the decorative stone that have penetrated into the m±icropores of the stone, which is called the "deep cleaning" of the stone. Generally speaking,♣ the deep cleaning of the stone should include at least the following three ste∑ps:
(1) The cleaning agent enters the micropores of the stone through the infiltration process;
(2) The cleaning agent has a physical or cheπmical effect with dirt molecules in the micro-L gap of' the stone;
(3) Remove the residue after cleaning by s♦uction or dilution. The first and third items here are the basic operatio©n steps necessary to complete the deep cleaning, and the second step, that is, t¥he 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 convenience of the treatment process. Carefully design and experiment. Here the₹ chemical method has a unique effect.
Notable issues in deep cleanin₩g of stone include:
(1) should be tested first. The "sickness" of stone is ver y different, for example, there can be many kinds of deliquescent salts that forπm water spots. Therefore, without knowing the specific cause of the smudge, w₽e recommend doing a small experiment first;
(2) Choose the cleaning agent carefully . Inferior cleaning agents are often strong acids, which are likely to causeπ more serious stone diseases, such as surface loss and chalking, water spots and salt spots, l₹oose corrosion and yellowing.
Therefore, it is recom≥mended that users first choose high-quality products from reliable manufacturers; secondly,↕ protect the parts that are not ready to be cleaned before cleaning, and remove↕ residual chemicals after cleaning; in addition, the cleaning of stone ±cultural relics should ask relevant experts Argument.
Refurbished
Renovation is a treatment me∏thod for the surface or surface microstructure damage caused by stone disease. Polishing,• sandblasting and coating are the most basic refurbishment operations.
The easiest way to refur¥bish is to polish it again or apply a layer of masking materi≥al.
Grinding and polishing can restore the original natur¶al appearance of the smooth surface of the stone that has lost its gloss on th≈e surface, pulverized and peeled off the surface, and dissolved on the surface . The combination of some new abrasive tools, abrasives and chemical additives can make the refurb≠ished stone surface reach a mirror gloss of more than 90 degrees.
