Large copper age cast copper handicraft maintenance instructions After the use of cast copper handicrafts for a period of time, due to contact with the air and the weather is wet, the protective layer on the surface of the product is gradually oxidized, resulting in the darkness of the copper surface, the loss of copper original color Severe oxidation will appear copper-green on the surface, and white spots or crystal marks will appear in the place where the sand hole discharges the internal moisture. The above-mentioned situation is a common problem of cast copper products. The following provides some maintenance knowledge. The above problems can be solved to the true nature of the product!
Pressed
Welded Steel Grating is made by the world first- class Italian ORSOGRIL
equipment, which can arrange the bearing bar and cross bar in longitude and
latitude order to certain distance. Cross bar is pressed into the bearing bar
by high tension resistance welding which is controlled by computer. So we can
produce high quality gratings with firm welding, smooth surface and high
strength.
Machines press-welded steel grid plates, as the name
suggests, is the use of machine pressure welding lines for steel grid plate
processing production, rather than artificial welding production, pressure
welding steel grid plate bearing capacity is stronger. The advantages of steel
grid welding are many, such as the flatness of the plate, the smaller error,
the more precise size, and the faster production.
The specific maintenance details are as follows:
(1) Regular inspection and care: Cast copper crafts sold in the store, some are placed in the warehouse and stored in the warehouse, and some are placed on the container for display and sale, but due to weather conditions and different ventilation conditions or other unforeseen factors, Usually after 15-30 days, the protective layer on the surface will have different degrees of wear and tear, so the surface of the product will lose its original color. At this time, it is recommended to open the package regularly every 15 days and use the Metal Polish metal care wipes provided for the store. Proceed as follows:
1 Wipe the surface of the copper product with a clean, soft cotton cloth, then apply the metal care wipe to the face and wipe it directly on the product.
2 First, wipe the product in a relatively convex place, and then slowly transition to a low concave place. The strength of the wipe should be mastered, and the natural transition effect of the product should not be destroyed.
3 If there is a brushed grain effect on the surface of the product, the cotton cloth should follow the direction of the wire drawing when wiping. Can not damage the texture of the texture, affecting the beauty of the product.
4 If there is oxidized copper green on the surface of the product (usually this oxidation will appear in the product's low recess or where the product is not easily touched), the amount of metal care agent can be adjusted according to the corrosion oxidation situation directly in the product. Wipe up until the copper green disappears to restore the true color of the copper. If it is a crystalline white powder that has been exposed through the sand hole, it can be cleaned off with a wood chip or a soft material tool and then wiped with a metal care agent.
(2) Daily Care: The cast copper handicrafts displayed in the store may be damaged by the customer in addition to the normal oxidation (for example, the hand sweat is often touched by hand, and the sweat on the hand may also be oxidized to the surface effect of the product to varying degrees. The place where the copper is often touched is bright and the color of the surrounding area is relatively dim, and the color of the product will be relatively dull. The color of the product will be less uniform and natural, and the level is clear. Therefore, daily care is not required. It is recommended to carry out the product once every 3-5 days. Daily care. Proceed as follows:
1 Use warm water and neutral detergent (wash and dissolve in water), gently wipe the surface of the product, and then dry it with a soft cotton cloth. This will clean the surface of the dust and lead to oxidation residue. The material does not destroy the original protective layer. Finally, it can be gently wiped on the surface with a small amount of metal care agent to protect it.
2 If the product touches water or other corrosive liquids, dry it with a dry cotton cloth as soon as possible, then clean it with a little metal care agent.
3 Try to keep the place where the products are displayed dry and ventilated. It is also necessary to pay attention to daily care.
The above product care and maintenance instructions are only customized for the material of 62 brass, white copper and copper in the cast copper product. Other metal products are not applicable.
