What are the production processes of stainless steel screen?

Stainless steel lattice is a new type of indoor and outdoor decorative partition product popular in recent two years, which is mainly customized.

In the process of design and planning, everyone should unify the indoor and outdoor decoration styles and coordinate the matching effects, which lies in the process. And the quality of technology is also related to the price.

When we choose stainless steel plaid, the first choice is the style, mainly European, Chinese, classical and modern styles.

Chinese stainless steel plaid cloth is welded by stainless steel pipes, forming a square with Chinese style. It looks simple, transparent and three-dimensional, suitable for lobby and window.

European style, mainly highlighting the softness of lines, mostly arc patterns, its plane visual effect is very good, suitable for indoor partition decoration.

Classical and modern styles are mainly reflected in the choice of surface texture and color, such as; Both red bronze and blue bronze reflect the classical charm.

There are usually two kinds of surface technology; One is mirror surface, and the other is wire drawing. Mirror is to polish the surface into a reflective effect similar to a mirror; Wire drawing passes through a wire drawing grinder, and the stainless steel surface is ground into strips of hair.

The reflective effect of stainless steel mirror is stronger than that of wire drawing, but it is easy to scratch, and the wear resistance of stainless steel wire drawing is stronger. Usually mirrors are mainly used outdoors. Wire drawing is mainly used indoors.

Everyone knows that stainless steel plaid is made of stainless steel, so how is the color on the surface of stainless steel plaid drawn?

In fact, most of the colors are colored by electroplating. Let's talk about electroplating.

Electroplating is a method that uses plated stainless steel mesh as cathode, and the cations in electroplating solution are precipitated on the surface of stainless steel mesh by direct current to form an electroplated film covering metal.

The anode in electroplating is sometimes the same as the plated metal, and sometimes it is an insoluble anode. The former uses a soluble anode, and the cations deposited on the cathode are continuously replenished through the dissolution of the anode, and the concentration of metal ions in the tank is relatively constant. In the latter case, cations in the solution are deposited on the cathode, while metal ions cannot be replenished through the anode, so the electroplating solution must be replenished from outside to keep the concentration constant.

Precautions before electroplating:

Before electroplating, the surface of the plated parts should be mechanically polished. Among the mechanical polishing methods as pretreatment, the most widely used are: wheel polishing and abrasive belt polishing to obtain a smooth surface; Polishing small workpieces with rollers; There are also wire brush method and liquid honing method which can form matte surface.

If the grease used for polishing is attached to the plated parts, it is particularly harmful to electroplating, and degreasing treatment must be carried out before electroplating.

In addition, the oxide film formed on the metal surface in the air seriously affects the adhesion of the electroplating layer. This oxide film can be dissolved in aqueous solution, such as dilute acid or potassium cyanide. Before electroplating, it should be soaked in these aqueous solutions for a period of time. After cleaning with water, it should be put into electroplating bath for electroplating while the surface is still wet.

In addition, when the atomic arrangement of electroplated metal and base metal is significantly different, the contact surface will have poor bonding, which will make the bonding force worse. Especially in mechanical grinding, when the surface has a thick working metamorphic layer, it is easy to have poor bonding force. Therefore, when electroplating, the working metamorphic layer on the surface should be removed and an unhardened metal with different atomic arrangements should be used as the intermediate layer.
