In modern solar film production technology, solar film is often made of aluminum, gold, copper, silver and other metals into a multi-layered high-insulation metal film layer by vacuum spraying or magnetron sputtering technology. Ceramic membranes have long durability, are not easy to oxidize, have a high life, good construction, and no internal resistance. The metal film has good heat insulation effect, but is easy to oxidize.
Metal film and ceramic film have their own strengths, the focus is to see your needs. If the thermal insulation performance is high, ceramic membranes can be used; in comparison, the metal film can be selected without blocking the signal, the metal film of the dragon
The organic film has a large market share due to its rich manufacturing materials, low cost per unit membrane area, and high packing density of the membrane module. However, organic membrane materials and most organic solvents, organic pollutants, etc. have non-polar or weak polarity characteristics, which causes the organic membrane to be easily contaminated by organic liquids and chemical reagents, greatly reducing the service life.
The inorganic ceramic membrane is affected by the material, resulting in high cost, high brittleness, and need to be filled in a specific casing. However, inorganic ceramic membranes have excellent chemical stability, high temperature resistance, chemical solvent resistance, strong anti-pollution ability; high mechanical strength, more suitable for separation of high viscosity and high solid content and complex fluid materials; inorganic ceramic membranes have narrow pore size distribution The use of cross-flow filtration can significantly increase the specific molecular weight and greatly increase the separation efficiency; the service life of the inorganic ceramic membrane is 3-5 times that of the organic membrane.
The use range of the organic film is often limited to a relatively simple treatment environment such as low concentration and micro-contamination, and the organic film is liable to be clogged and difficult to recover. Jiufu High-tech inorganic ceramic membranes are rich in specifications, including microfiltration, ultrafiltration and nanofiltration. Membrane separation technology is in the leading position in the world. It has been widely used in chemical and chemical processing, food processing, environmental water treatment, and new energy treatment.
In fact, the difference between ceramic film and metal film is still there. The difference between organic ceramic film and inorganic ceramic film is there. Although it is similar in the name, it is not the same in general. Everyone should not buy it. The purchase was wrong.
