We know that there are more and more bronze statues in the collection, but we all know that the bronze Buddha statue will definitely get dirty after a long time. How can we clean the bronze Buddha image without letting it fade? Let's briefly understand it.
Prepare coconut oil and distilled water for the cleaning of bronze Buddha statues. First, pour a small amount of coconut oil onto a clean soft cloth and gently wipe it. This will help the maintenance of the bronze Buddha statue. The reason why the coconut oil is used is because the material contained in the coconut oil does not cause the bronze Buddha image. The fading, this must be noted.
Regular wiping of copper Buddha statues with a soft cloth dipped in distilled water is also very important. At the same time, we can add some mild soap to the distilled water to clean the dirt. For some corners that cannot be rubbed, we can use a soft brush. Handling, so that the bronze Buddha image can be cleaned and protected. Below we learn the specific method operation.
1. Silver oxide method. Contact with cuprous oxide with silver oxide to block the exposed surface of cuprous chloride to control the corrosion of bronze statues. First, the powdery rust is removed by mechanical means to reveal a grayish white waxy cuprous chloride. Then, the silver oxide and the alcohol are adjusted into a paste, coated on the surface of cuprous chloride, and placed in a humid environment to fully act to form cuprous oxide and copper chloride, covering the surface of the cuprous chloride. Both are stable salts, so many operations, until the object is placed in a high humidity environment, there is no corrosion point of powdery rust. This method is suitable for objects with speckle-like local corrosion and articles with metal inlays.
2, benzoquinone triazole method. Benzotriazole is a heterocyclic compound that forms a stable complex with copper and its salts. It forms an insoluble and relatively strong transparent protective film on the surface of the copper alloy, which inhibits and stabilizes the copper engraving and prevents water vapor. And erosion of air pollutants. The complex protective film is formed by removing the soil oil on the surface of the bronze Buddha image by using distilled water, an organic solvent such as toluene or acetone, and then immersing it in a solvent of benzotriazole alcohol. However, benzotriazole is susceptible to heat sublimation and loses its protective effect. Therefore, a layer of polymer material should be applied to the surface of the copper sculpture to make a sealing film.
3. Alkaline immersion method. The etched bronze statue is immersed in a sodium sesquicarbonate solution to gradually convert the copper chloride into a stable copper carbonate, and the copper ions of the bronze are replaced and transferred into the immersion liquid. The immersion liquid should be replaced regularly until no chloride ions appear in the immersion liquid. The utensils were then repeatedly washed with distilled water to remove the lye, dried and sealed. The alkali solution only extracts the chloride and retains the corrosive layer such as the colorful malachite, without damaging the original appearance of the bronze sculpture. The disadvantage of this method is that the displacement reaction time is long: in addition, the chloride is not only attached to the surface of the rust layer, but also penetrates into the deep part of the crust, which is difficult to be completely replaced.
These are the common methods for daily cleaning and maintenance of bronze Buddha statues. You can refer to them. For more information about bronze Buddha statues, you can pay attention to China Copper Sculpture Industry Network, visit http://
A smart watch is a smart watch with a built-in smart system, equipped with a smart phone system and connected to the network to achieve multiple functions. It can synchronize calls, text messages, emails, photos, music, etc. in the phone. Display methods include pointers, numbers, images, etc.
With the development of mobile technology, many traditional electronic products have also begun to add mobile functions. For example, watches that can only be used to see the time in the past can also be connected to the Internet through smart phones or home networks to display caller information, Twitter and News feeds, weather information, etc. This type of product is mainly designed for consumers to use in situations where it is inconvenient to use a smartphone, such as when they are riding a bicycle or carrying something in their hands.
