Titanium filter element titanium powder is used as raw material, through classification, molding, sintering, welding processing machinery, such as the process of a new type of efficient porous filtration material, because of its pore and filtering precision can be adjusted in a wide range, is widely used in self-lubricating, filtration, separation, catalysis, out the flame, heat, hot electron and gas distribution, etc.
Titanium filter core has corrosion resistance, high temperature resistance, high strength, easy to ensure the filtration accuracy, easy to regenerate and other excellent performance;Titanium filter core is made of titanium powder after forming and sintering at high temperature, so the surface particles are not easy to fall off.The service temperature in the air can reach 500~600℃;Suitable for filtration of various corrosive media, such as hydrochloric acid, sulfuric acid, hydroxide, seawater, aqua royum, iron, copper, sodium and other chloride solutions.It has excellent mechanical properties, can be cut, welding and other machining, high compressive strength, internal pressure failure strength up to more than 2MPa;The filter precision is easy to ensure, even in high temperature and high pressure work, aperture will not deformation.Its porosity can be up to 35~45%, the pore diameter is evenly distributed, the amount of pollution is large, and the regeneration method is simple, can be reused after regeneration.
The application of titanium filter core is a kind of progress, now has been applied in many fields, and showed a very good effect, but for the cleaning of titanium filter core you may not be very clear, let's take a look at the cleaning of titanium filter core need to pay attention to what, and what are the better methods:
Generally speaking, the following methods are used for cleaning titanium filter element:
Alkaline wash: alkaline wash refers to the use of 3-5% sodium hydroxide analysis of pure solution immersion 30-60 minutes, about 40 degrees can be about the temperature.It works best in ultrasonic cleaning machine.Generally, after immersion, filter deionized water or injection water is used to flush the inside and outside to the neutral, measuring the conductivity.Blow dry with pure air ≥ 0.4mpa.At present this method is more common, is one of the most popular methods.
Pickling: have alkali to wash nature also can have pickling, pickling is to use 5% nitric acid solution to soak 8 hours above, the temperature is about 40 degrees can.Best in ultrasonic cleaner.After soaking, wash with filtered deionized water or injection water inside and outside to neutral, measure the conductivity.Blow dry with pure air ≥ 0.4mpa.
The above two methods are currently the most commonly used, but also the most simple cleaning method, but in the cleaning process need to pay attention to.The two methods described above can be used independently or interchangeably.If there is an ultrasonic cleaning machine, combined with this method, the effect is very good.Secondly, in the cleaning process, you can choose different cleaning methods according to the pollutants, generally speaking, organic pollution, can use active agent cleaning, cell debris pollution can use combined enzyme cleaning, food and beverage pollution using high concentration of citric acid cleaning, so the effect is better.
