Xiao Lu teaches you the difference between imitation copper and copper aluminum doors

[China Aluminum Network] Now many people will choose imitation copper doors, and now most of the imitation copper doors on the market are iron gates, the appearance of the appearance is still possible. The imitation copper doors used in previous years were produced with cold-rolled plates. After one or two years, rusted paint will appear. With the innovation of the market, some manufacturers will use galvanized steel plates because of the surface of galvanized steel plates. The processing requirement is relatively high and it is not easy to rust. The door of the steel plate appeared to be out of paint. Therefore, the copper-aluminum door appeared. What is the difference between the copper-aluminum door and the imitation copper door?

The lifespan and price of the high-simulation copper door and the generic imitation copper door are quite different. The ordinary imitation copper door has low cost. The damage caused by ultraviolet radiation and wind and rain can easily be powdered and faded. However, the high-simulation bronze door uses anti-ultraviolet acrylic, strong weather resistance, and the paint has been subjected to surface treatment and can be used for a long time without discoloration.

Copper and aluminum doors look at the color, ordinary copper imitation knowledge inside the copper powder into some copper powder, electrostatic spraying, reduce the adhesion with the plate, so easy to pulverize the paint, the color will appear uneven, hand touch It will feel rough. The high simulation of copper door with UV acrylic, strong metal, uniform color.

There are many ways to distinguish between imitation copper doors and copper-aluminum doors. Now that the manufacturers of some copper-aluminum doors are relatively small, they are all sprayed according to the requirements of selling.

Graphite Powder soft, dark gray; greasy feeling, can contaminate the paper. Hardness of 1 to 2, along the vertical direction with the increase in the hardness of the hardness can be increased to 3 to 5. Specific gravity of 1.9 to 2.3. In the isolated oxygen conditions, the melting point of more than 3000 ℃, is one of the most resistant minerals. At room temperature, the chemical properties of Graphite powder is relatively stable, insoluble in water, dilute acid, dilute alkali and organic solvents; materials with high temperature conductive properties, do refractory materials, conductive materials, wear-resistant lubricating materials.
