How to deal with brass refurbishment? How to deal with the fading of brass plates?

Hello, Brass.

It belongs to metal, the method of metal renovation is generally polishing, there are many process methods for metal surface polishing, and the appropriate polishing process is selected according to the size, shape and complexity of your brass workpiece.

a) Mechanical polishing, one is manual mechanical polishing, the traditional method is carried out on a polishing machine equipped with a polishing wheel. The polishing wheel is generally made of cloth, velvet, leather or special kraft paper.

It is cut into several layers of circular overlapping seams to make a wheel shape, and is installed on the shaft of the polishing machine, so that after it rotates, the parts are pressed on the wheel for polishing. The other is belt polishing, which is a polishing method that puts the workpiece to be polished on the polishing belt with abrasive materials and rubs it to achieve the polishing effect. The equipment is simpler, cheaper, and you can even make and install it yourself.

The polishing quality of the workpiece is easily affected by various factors, and its external light varies with the skill of the polisher, and it is difficult to reproduce.

2) Chemical polishing, the workpiece is soaked in a chemical solution, and due to chemical erosion, the microscopic convex part of the surface is preferentially dissolved compared with the concave part, so as to achieve the purpose of leveling and polishing effect. The chemical solution of polishing consists of corrosives, corrosion inhibitors, surfactants.

brightener and other additives. Guangzhou Yishun Chemical has several chemical polishes for copper metal, beryllium copper.

Polish, brass polish, copper.

Polishes, polishes, etc. This method is characterized by simple equipment, can polish large quantities, large and complex parts at the same time, high production efficiency, low cost, no need for DC power supply and electric hangers.

3) Magnetic grinding and polishing is a method of grinding the workpiece with an abrasive brush formed by magnetic abrasives under the action of a magnetic field to achieve a smooth surface. In the machining process, the magnetic field can be kept constant and the workpiece moves, or the magnetic field can be changed, and the workpiece does not move. This method is highly efficient, high-quality, and the processing conditions are easy to operate and control.

4) Ultrasonic polishing is to put the workpiece in the abrasive suspension and then put it into the device with an ultrasonic field, relying on the ultrasonic effect to make the abrasive play a grinding and polishing role on the surface of the workpiece. Ultrasonic technology can also be used in conjunction with chemical polishing and electrolytic polishing.

I only know that copper purification, adding two electrodes in the copper sulfate solution, one with graphite rods, or pure copper, and the other with blister copper, to carry out the galvanic cell reaction, the positive electrode will get pure copper, which can also play a role in refurbishment.

How to clean and refurbish copper jewelry: Wash it with hot, soapy water, then dry it with soft leather and blow dry it thoroughly. To clean dirty copperware, boil it for a few hours in water with salt and white vinegar.

If there are lumps of dirt and soot on the bronze, or if it has been corroded by the air, it can be immersed in cold light ammonia, gently scrubbed with a wire, then quickly dried and rubbed with a paste of wood ash and nail drunk. If the copper ware loses its luster, you can use a mixture of salt and white vinegar or sprinkle salt with half a lemon to rub, rinse it immediately, then wash it with hot soapy water, then rinse it with clean water and wipe it dry. If the copper is left for a long time, the surface will turn black, if wiped with ammonia, the surface can be as bright as new.

Apply a little vinegar to the patina, dry it and wash it with water. The patina can be rubbed with a cloth dipped in kerosene and then polished with tooth powder. The inside of the food contact is patina, which can be wiped off with wood ash.

The tin foil of the silverware corner pack cigarette is dipped in fine salt to wipe it, and it can be as bright as new. The paint stains on brass products can be wiped with a sponge dipped in methanol, or lemon juice can be mixed with metal rubbing paste to help keep brass products clean for a long time. Brass products with varnish have dirt, you can apply a paste made of potassium bitartrate and lemon juice to the copperware, leave it for 5 minutes, then wash it off with hot water and dry it with a soft cloth.

To clean the bronze, after removing the dust, first rub the surface with a little hot linseed oil and then with leather.

Copper has been used in different ways since ancient times to promote good health. Copper refers to the elemental copper matter, which is commonly known as pure copper. Copper is used in a wide range of applications, and is often made into various jewelry, copper plates, rods, pipes, and foils, etc., and copper products made of copper are used in the construction industry and daily necessities.

There are 3 ways to clean pure copper jewelry:

If the surface has developed patina, it can be cleaned with vinegar.

Cut the lemon in half and wipe it with a small amount of salt, or soak the jewelry in a mixed solution of lemon juice and baking soda.

The ketchup in the kitchen can also be used to clean copperware, spread the ketchup evenly on the copper jewelry, rinse it with water after a few minutes, and wipe it dry.

Extended information: Copper is a transition element, the chemical symbol Cu, English copper, atomic number 29. Pure copper is a soft metal, the surface is reddish-orange with metallic luster when it is first cut, and the elemental color is purple-red.

Good ductility, high thermal and electrical conductivity, so it is the most commonly used material in cables and electrical and electronic components, and can also be used as a building material, which can form many alloys.

Hello, copper jewelry can be cleaned with vinegar if it is rusty. You can also slice the lemon and wipe it with a pinch of salt, or you can use the polishing technique and ask someone to clean and refurbish it for you. Wash with hot, soapy water and then dry with soft skin.

You can also use white vinegar and salt to boil in water, soak for a few hours and then scrub clean.

Soap or mild detergent: If your brass jewelry is dusty or dirty, rather than darkened, soak it in lukewarm soapy water and wash it off with a soft cloth. Particularly dirty areas can be gently brushed clean with a toothbrush.

Copper jewelry cleaning and refurbishment is cleaned with ultrasonic. Then after washing, take care of it with oil, and it will look new.

Wash with hot soapy water, then dry with soft skin, blow dry thoroughly, clean very dirty statistics can add salt.

It will not fade, but it will oxidize.

1.If copper is plated, it will fade over time, and this discoloration cannot be repaired. Pure copper ornaments, a long time will be because of oxidation, become dull and dull, I think, this can show the ornaments of the sense of age and taste, old objects and high-grade are like this.

If you want to restore the shine, you can use toothpaste to wash it.

2.Copper jewelry will react chemically with water in the air when exposed to the air, so there will be rust and discoloration. For the copper surface has been oxidized and rusted, it is recommended to clean the oxide layer, patina and other rust and impurities on the surface first, and then use the plastic frame to directly soak the copper parts in the copper passivation solution, use it at room temperature, soak for 15 minutes, and when the time is up, take out the workpiece, rinse the surface passivation solution with water, and then dry the packaging.

First of all, gold-plated products will fade, there is no gold-plated jewelry that does not fade, only gold-plated jewelry that retains color for a long time, good maintenance, natural color retention time is long, poor maintenance, and fast color loss. Plating products are available.

Due to the activity of copper elements, copper products are easy to react with oxygen in the air to form an oxide layer, which affects the appearance and physical properties of copper products. Oxidation of brass surfaces can be done as follows.

Cleaning (different cleaning solutions are used for different copper products, ReneSola C101 and C102 can treat the oxide layer on the surface of copper products).

Rinse with water. Chemical polishing, using ReneLuminizer B200, can quickly restore the luster of the brass surface.

Rinse with water. Passivation. In order to avoid the re-oxidation of brass products, it is necessary to passivate the surface of the chemically polished products to form a protective film on the surface of the products, and the Renebla copper passivator CP401 can effectively block the oxidation reaction between air and copper molecules.

At this time, brass products can be stored normally for a longer period of time. If you need to enhance the passivation effect and want to have a longer lasting shine effect, you can choose to add a layer of sealant to the passivation layer, ReneSola S501 sealant has a strong corrosion resistance and anti-fingerprint effect, which can help you maintain the shine of copper products for a longer time.

Can <> still work when it turns black?

Kiss, it can still be used when it turns black, but it needs to prevent oxidation in the process of use, because the blackening of brass is caused by oxidation.

Vinegar soaking method: Put the copper in a container and pour in the edible vinegar. After 24 hours, take it out, brush off the rust, wash it with water, and wipe it dry in the shade.

Boiling water immersion method: Put the copper in a bowl and pour boiling water at a temperature of 80 to 90 until it is submerged. After 5 minutes, take it out, brush it clean with a brush, and dry it in the shade.

Cleaning agent method: use copper bright cleaning agent MS0217 for cleaning, then wash with water, and dry in the shade. <

1. Vinegar soaking method: wash the oxidized copper, put it in a container, and pour a little edible vinegar until it is submerged. After 24 hours, take it out, brush off the rust with a small brush, wash it with water, wipe it clean and dry.

2. Boiling water immersion method: put the rusted oxidized copper into a bowl and pour boiling water at a temperature of 80 to 90 until it is submerged. Take it out after 5 minutes, brush it clean with a small brush and dry it in the shade.

In case of serious oxidized earth rust, the water can also be heated to boiling to make it fall off.

3. Cleaning agent method: use the special copper bright cleaning agent MS0217 for cleaning, and then wash it with water, and dry it to quickly restore the original gloss of the copper parts, so that it is as bright as new.

Start by dusting with a soft cloth and then soak the soft cotton cloth with warm dish soap, making sure it's only slightly damp. Gently wipe the brass surface. When the surface is clean, soak the cloth in clean water, wring it out and wipe the object again so that no soap remains.

Finally, take a dry cloth and wipe it dry.

If the brass objects are stained with oil, we use warm water and neutral detergent to clean them. Use a soft cloth dipped in diluted detergent to wipe the brass object all over the body.

Toothpaste can be used as a mild polishing agent. Mix equal proportions of white vinegar with water and add a cup of flour, which can also be used as a polishing agent. Use a toothbrush to remove dirt from the crevices on brass objects with polish and do so gently to avoid wear and tear.

Brass is a zinc-copper alloy. As dust and oil build up, brass can become dull. Hot water to remove the paint coating.

Place the brass object in hot water. And make sure it starts to swell slightly. The lacquer starts to expand as the metal starts, but when the object cools down again, it shrinks slightly, which does not happen with the coating.

When an object is cold, the varnish peels off its surface.

Make sure the brass is clean, with half of the lemon, squeeze the juice into a small bowl. Add sparkling water or table salt. Use a soft cloth to apply the resulting paste to the brass object. Salt or soda can also polish brass.
