Porous titanium plate is a material with excellent filtration performance, which is usually manufactured by metal powder rolling method. Powder rolling is a process in which metal powder is used as raw material to directly roll metal into a product. First, it is rolled into a strip on a powder rolling mill, and then sintered, cold rolled (or hot rolled), and annealed to make dense or porous. Finished sheet and strip.
The porous titanium plate made of titanium metal powder has the excellent corrosion resistance of titanium, can resist the erosion of various concentrations of nitric acid and most acid-base solutions, and is non-toxic, high temperature resistance, high strength, high porosity, It has the advantages of uniform ventilation and easy cleaning.
Application of porous titanium plate
The use of ozone to treat drinking water and industrial wastewater is a technology that has developed rapidly at home and abroad in recent years. This method is: the ozone is evenly put into the sewage through the porous plate, and the chemical reaction occurs with the sewage, so as to achieve the purpose of disinfection, decolorization and purification.
Therefore, it is required that the porous sheet used is resistant to corrosion by industrial sewage and ozone, and has high porosity and gas ratio, uniformly distributed pore size and certain strength. Some units in my country that use the ozone method to treat sewage have used polyvinyl chloride perforated plates, ceramic perforated plates, glass perforated plates and other materials in the past, but they cannot meet the requirements due to poor corrosion resistance and low strength. solved this big problem.
At present, porous titanium plates have been used as ozone diffusion plates in the treatment of printing film sewage, organic dye sewage treatment, oil refining sewage treatment, hospital sewage treatment, and rocket engine test sewage treatment. In the treatment of printing film wastewater, the original use of polyvinyl chloride porous plate, the service life is only 350 hours, after replacing the porous titanium plate, the service life is increased to 3 years. In the ozone treatment of oil refining wastewater, PVC perforated plates were used, but the ozone absorption rate was only 65%, which wasted a lot of ozone and increased the cost of wastewater treatment. The use of porous titanium plates increased the ozone absorption rate to 85%. , greatly improving the processing effect.
In addition, porous titanium plates can also be used as various filters, reverse osmosis devices, and medical materials. In short, the new material of porous titanium plate has shown its strong vitality and will be widely used in all aspects of life in the future.
