Hardware electrical ScrewsWhat are the ways to dispose of the exterior? Screws are generally required through the appearance of disposal, appearance disposal of a lot of methods, commonly used in electroplating, oxidation, phosphating, non-electrolytic zinc coating disposal. Electroplating screws are widely used in automobiles, procrastination machines, home appliances, instrumentation, aerospace, communications and other occupations and categories.

Why are you right?Hardware electrical ScrewsStop the appearance of disposal? Simply put, it is to maintain the screws from friction damage, and to give the screws appearance beautiful, anti-corrosion, anti-loosening effect and so on. Below Chuang River in order to introduce screws on the exterior disposal of 20 ways.

1, plated with three prices of white zinc, that is, white zinc plating. White Zinc plating refers to the surface of the screws coated with a layer of white zinc to play a beautiful, anti-rust and other effects of the disposal method.

2, plated with three prices of blue zinc, that is, blue zinc plating. Blue Zinc plating refers to the surface of the screws plated with a layer of blue zinc to play a beautiful blue, anti-rust and other effects of the disposal method.

3, plated three-price colored zinc, that is, galvanized zinc. Galvanized zinc refers to the surface of the screws coated with a layer of colored zinc to play a beautiful, anti-rust and other effects of the disposal method.

4, plated with three prices of black zinc, that is, black zinc plating. Black Zinc plating refers to the surface of the screws plated with a layer of black zinc to play a beautiful, anti-rust and other effects of the disposal method.

5, NYLOK treatment, plating resistance, is a relaxation technology, falling screw anti-loosening technology is the first in the United States in the world to develop victory, it is special technology to make special engineering resin * adhesion on the snail teeth, the application of engineering resin data rebound, so that bolts and nuts in the locking process through extrusion to reach the vibration and impact * Resistance, thoroughly dealing with the loosening of the screws.

6, imitation gold disposal, a part of the appearance of 14-18K gold color of the appearance of the disposal method. Mainly used in construction, hardware, lighting, jewelry and other industries of electroplating.

7, gold-plated, gold-plated, is a decorative process, is also one of the commonly used vocabulary. * At first, it refers to a thin layer of gold plated on the exterior of the artifact.

8, copper plating treatment, after technical disposal, so that the appearance of the screws into a bronze.

9, Plating Dacrome, technology born in North America, is a zinc powder, aluminum powder, chromic acid and deionized water as the main components of the new anticorrosive coating.

10, high temperature pot black, is a screw of a high temperature pot black disposal method.

11, Copper plating, copper plating is usually divided into electroless copper plating and copper plating. Electroless copper plating is in the surface of catalytic active substances such as palladium, through the effect of formaldehyde and other recovery agents, so that copper ions are restored and separated.

12, nickel plating, by electrolysis or chemical methods on the metal or some non-metallic plating on a layer of nickel method, called nickel plating. Nickel plating is divided into ni and electroless nickel plating. Nickel plating is a nickel salt (called main salt), conductive salt, pH buffer, wetting agent composition of the electrolyte, anode metal nickel, yin plating parts, through direct current, in the cathode (plating) on the accumulation of an average, fine nickel coating.

13, copper plating base nickel.

14, Silver plating, the coating is used to prevent screw corrosion, add screw conductivity, reflective and beautiful. Widely used in electrical appliances, instruments, surfaces and lighting appliances and other manufacturing industries. In order to prevent the discoloration of silver plating, ordinary after plating treatment, mainly immersion, chemical and electrochemical passivation, plating of precious metals or rare metals or coated cover layer.

15, ordinary pot black, is a screw of a temperature pot black disposal method.

16, head spray paint, spray paint artificial paint, with lead nitrate veins, resins, pigments, solvents and so on. Usually with spray gun on the average spray on the surface of the screws, water resistance, oil resistance, dry fast. The substance is toxic and has a certain effect on the body, and different brands of spray paint vary in toxicity due to the content of the ingredients. Special attention should be paid to safety in the use, to prevent inhalation and skin contact.

17, the appearance of dyeing, theHardware electrical ScrewsThe appearance stops the chemical coloring method simple process, the control is simple, the efficiency is high, the cost is low, the color is gorgeous.

In addition, the appearance of the screws of the data also *8, * 9 Kinds of phosphating, the 20th oxidation and so on.

Screw appearance disposal has what way, this article Chuang River for you to introduce 20 kinds. About screw thread, the use of not only the demand has beautiful and beautiful characteristics, must request anti-corrosion effect, anti-loosening and other effects
