Daily maintenance of copper products

A decontamination

We usually use a metal cleaner to remove the dirt on the copper strip surface and pay attention to the dilute concentration of the cleaner. The dilution concentration of detergent has a great relationship with the cleaning effect. Sometimes the dilution is twice that, which can make a huge difference in effectiveness. Generally speaking, with the increase of dilution concentration, the purification capacity will also be enhanced, but after reaching a certain dilution concentration, the purification capacity will not be significantly improved. Dilution concentration should be controlled in 1:5 ~ 1:10. Remember not to use raw liquid for cleaning, otherwise the detergent will remain on the cleaning material, and difficult to clean.

Control the temperature of the detergent. In general, the higher the temperature at which the polymer moves, the higher the temperature of the detergent, and the stronger the cleaning effect. But each detergent has its own optimal cleaning temperature, so don't go as high as possible. Especially for non-ionic cleaners, if heated too high, the cleaner will be turbid. the solubility of the cleaner in the water will be reduced, and some components will be inactivated by heating, thus reducing the decontamination ability. Therefore, the temperature of non-ionic detergent should be controlled below the turbidity point.

The second store: Store with care

1. Reduce friction and prevent scratching

It is characterized by soft texture, hardness is only 2.5-4.5. Ordinary matter is usually harder than she is. In addition, if the use of hard objects, scratching repeatedly wipe, it will damage the surface of the smoothness, smoothness and brightness, so that the loss of beauty. When storing multiple pieces of jewelry, it's best to wrap them in soft cloth and place them in a jewelry box. Do not mix gem jewelry and pearl jewelry, which may cause friction. Install them separately. Pivot check, it is best to take off during strenuous activities or housework; In addition, had better not wear in gale season, lest blow sand, burnish dim.

2, anti-collision, anti-collision

All metals will not withstand impact, which will cause varying degrees of damage and the surface will fall off. Therefore, when placing moving metal, please keep away from places frequented by vehicles or people and exercise extreme caution.

3, anti-corrosion, prevent harmful substances

Three derusting

Mechanical derusting: For small motors, pneumatic tools (such as Angle grinding wheels, grinders, etc.), use their impact force and sanding ability to remove rust and dirt. Mechanical rust removal efficiency is high, widely used in construction site.

Sand blasting: this is an efficient, high quality product. The method of descaling quality is more thorough and can remove impurities attached to the metal surface and rust layer. The sandblasted surface has good mechanical adhesion to the film. Sandblasting treatment includes dry sandblasting, wet sandblasting, closed dust-free sandblasting, shot blasting and high-pressure water spraying.
