Metal powder serves as the only raw material for the sintered metal powder filter; no binders are used. It is generated by cold isostatic pressing and then sinters at high temperatures.​By adjusting the process parameters and metal powder particle size, the pore size and distribution of the component can be changed. Utilize the pore structure, material composition, compressive strength and other characteristics of different filter materials to develop filter products suitable for users.

When the filter cake on the surface of the sintered metal powder filter element reaches a certain thickness, due to its high-strength performance characteristics, by backwashing or backflushing the filter element under a specific reverse pressure, the filter element can be cleaned and reused.

Features

Strong resistance to corrosion

An inert metal with exceptional corrosion resistance is titanium. Strong alkali and strong acid media can be filtered using the titanium metal rod filter element. It has a wide range of applications in the chemical industry and in the filtering of the pharmaceutical industry's organic lysozyme production process.

Good tolerance to high temperatures

The titanium filter element has a high temperature resistance that goes up to 300°C. In operational situations with high temperatures, this function is frequently used. The temperature resistance of the filter element made of polymer materials is normally limited to 50°C. The support and filter membranes will alter if the temperature goes beyond 50°C. It is frequently employed in the filtration of high-temperature liquids and steam filtration (steam filtration in fermentation processes), despite having a significant accuracy variance.

Superior mechanical qualities

With external pressure of 20 kg and internal pressure of 10 kg of destructive force, the titanium rod filter element has strong mechanical qualities and may be utilized in high pressure and quick filtration processes. The pore size of other polymer filter components will fluctuate or even break down when the external pressure is more than 0.5 MPa.

Good regeneration

Due to its superior corrosion resistance, high temperature resistance, and high strength performance, titanium rod filters have a good regeneration effect. There are two types of regeneration: chemical regeneration and physical regeneration treatment.

Physical regeneration method:

(1) Pure water recoil

(2) Steam blowback

(3) Ultrasonic cleaning

Chemical treatment method:

(1) Alkaline washing

(2) pickling
