Aluminum curtain wall plate treatment process
[China Aluminum Network] The treatment process of aluminum curtain wall panels can be divided into two methods, one is anodizing, and the other is electrostatic spraying. Anodized oxide film is generally more than 12μ, the color is only bronze and white, the color is monotonous, more serious drawback is the color of each aluminum plate surface shades are different, many pieces of curtain wall plate together to form a curtain wall overall effect Very ugly. This disadvantage can be said to be impossible to eliminate, not because of the production technology, but because the aluminum plate is not a batch number, chemical composition, there are small differences, plus the electrolytic tank current density and other factors can not be exactly the same, so The number of colors after oxidation is different, and the single leaflets may not be obvious. Therefore, aluminum surface treatment of aluminum curtain walls must not be anodized. Another method of surface treatment of aluminum curtain wall panels is electrostatic spraying. Spraying is divided into powder spraying and liquid spraying. Powder spray material is mainly: Polyurethane, poly swell resin, epoxy resin and other raw materials with high color retention pigments, can get dozens of different colors of spray powder. The spray powder, resistant to impact abrasion, under the impact of 50 kg, aluminum plate deformation, spray coating without cracks, no loss of intact layer, anti-dilution acid and mortar. The shortcomings of long-term exposure to UV rays, easy to produce a few years later the difference in the color of the yin and yang. Spray powder produced by many domestic manufacturers, the weight difference is very large, and some powder containing gold shavings after the powder hanging on the wall, with the sun angle changes, day and evening changes, the wall color shades are different, The use of powder spray coating has attracted attention.
Zhejaing Sealand Technology Co., Ltd. is a trustworthy manufacturer of Mass Flow Meter, Mass Flowmeter, Mass Meter, Flow Meter, Flowmeter, ATEX, IECEx & CE approved. The product range covers different size from DN03 to DN150, and bigger sizes are being developed.
Sealand mass flow meter is designed and produced according to world`s latest Coriolis technology with exelent appearance, stability and accuracy to measure mass flow rate of a fluid traveling through a tube, widely applied to alternative energy, oil & gas, chemical, food & beverage, industrial energy, marine, power, pulp & paper, water & wastewater industries, etc.
Mass flow meter measures the mass based on Coriolis effort. The operating principle involves inducing a vibration of the tube through which the fluid passes. The vibration, though not completely circular, provides the rotating reference frame that gives rise to the Coriolis effect. While specific methods vary according to the design of the flow meter, sensors monitor and analyze changes in frequency, phase shift & amplitude of the vibrating flow tubes. The changes observed represent the mass flow rate and density of the fluid.
