The porous titanium plate made of titanium metal powder has the excellent corrosion resistance of titanium and can resist the erosion of various concentrations of nitric acid and most acid and alkali solutions.
At the same time, it also has the advantages of non-toxicity, high temperature resistance, high strength, high porosity, uniform air permeability, and easy cleaning.
Application of Titanium Powder Filter Plate
The ozone method for treating drinking water and industrial wastewater is a technology that has developed rapidly in recent years. The working principle of this method is: ozone is evenly injected into the sewage through a porous sheet, and chemically reacts with the sewage to achieve the purpose of disinfection, decolorization, and purification.
Therefore, the porous plate used is required to be resistant to the corrosion of industrial sewage and ozone, have a high porosity and gas content, uniform pore size distribution, and have a certain strength.
In the past, some sewage treatment plants used polyvinyl chloride porous plates, ceramic porous plates, glass porous plates, and other materials for sewage treatment, but these materials have poor corrosion resistance and low strength and cannot meet the requirements. The invention of titanium powder filter plate solves this problem.
At present, porous titanium plates have been used as ozone diffusion plates in the treatment of printing film wastewater, organic dye wastewater, refinery wastewater, hospital sewage, rocket engine test sewage, etc.
In the treatment of printing film wastewater, the original polyvinyl chloride porous plate had a service life of only 350 hours. After replacing it with a porous titanium plate, the service life was increased to 3 years.
In the ozone treatment of refinery wastewater, polyvinyl chloride porous plates were originally used, but the ozone absorption rate was only 65%, which wasted a lot of ozone and increased the cost of wastewater treatment. After using porous titanium plates, the ozone absorption rate was increased to 85%, greatly improving the treatment effect.
Titanium powder filter plate can also be used as various filters, reverse osmosis devices, medical materials, etc. The new material of porous titanium plate has now shown strong vitality and will surely be widely used in all aspects of life in the future.
