What Is Sintered Metal Powder Tube

Sintered porous metal is made by a process called powder metallurgy, which involves mixing powder particles with binder materials to form a "green compact" that is then sintered at high temperatures. The binder material, which has a low melting point, is then burned off, leaving behind a porous metal structure.The size and shape of the pores can be controlled by adjusting the particle size and distribution, as well as the sintering temperature and duration.

 

How is sintered porous metal made?

We take the manufacturing process of sintered porous stainless steel filters as an example.

Firstly, the stainless steel powder raw materials are screened and filtered - tanked into the mold - applying pressure die casting - sintering process - demold - Surface treatment- finished.

What are the advantages of using high quality sintered metal tubes?

1. Strong material,resistance mechanical strength and flexible shape.

2.Good gas permeability.

3. Multiple pore size distribution

4. Stable performance can cope with high pressure from various liquid phase without deformation.

5. sintered metal tube work in extremely harsh environments such as high pressure and apply heat.

6. Can adjust the size of the hole

7. Corrosion resistance.

8. The equipment is easy to clean and does not need to be shut down for a long time.

Is sintered metal powder Tube Stronger？

The tubes supplied by Xubo have superb mechanical properties and can withstand working pressures of up to 4 kg. Therefore, our products can be applied in the process of high pressure and fast filtration. Other polymer cartridges will change their pore size or even be broken through when the external pressure exceeds 0.5Mpa.

 

Sintered Filter Working Principle

Powdered sintered metal is a metal porous filter material made by powder metallurgy method. Its internal pores are arc-shaped, configured in a longitudinal and transverse manner, with uniform pore size distribution, and the filtration mechanism is typical of deep filtration.

 

 

Sintered Porous Metal Filter Element Specific Applications

Different filter elements are used for different purposes depending on the materials, which is widely used in the filtration of liquid and gas.  

1. Industrial field: sintered cartridge can be used in filters in food, chemical, pharmaceutical, water treatment and other industries to remove solid impurities, suspended matter, particles, bacteria, etc.

2. Automotive industry: metal sintered filter elements can be used in oil filters and air filters in automobile engines, which can filter dust and particles in the air, protect the engine and extend its service life.

3. Electronic industry: The metal sintered filter element has the characteristics of high temperature resistance and can be used for microfine filtration in high temperature, high pressure and high humidity environment of electronic products, which can be used to protect electronic devices from external influence and ensure product quality and service life.

4. Petroleum industry: metal sintered cartridge can be used for filtration of petroleum polyester filtration chemical, and used to remove bad reaction products and impure substances.

5. Medical and health care: metal sintered cartridges can be used in high purity water filters and filters in pharmaceutical manufacturing in the medical and health care industry to remove harmful substances such as bacteria, viruses and microorganisms.

 

According to several common applications, the efficiency methods are as follows:

1, the pharmaceutical and chemical fields of decarbonization and filtration, to often use back-blowing, backwashing methods and combined with ultrasonic cleaning the best results.

2, water production industry, because the surface of the filter element is mostly retained by non-water-soluble salts and oxides, the general use of 5% nitric acid immersion, without ultrasonic cleaning, can achieve the cleaning effect.

3, raw liquid filtration, to combine the chemical nature of pollutants, respectively, the following methods of cleaning:

(1) Alkali washing: 3-5% analysis of pure solution of hydroxide Na should be left in contact with water for 30-60 minutes at about 40 degrees; an ultrasonic cleaner would be best. After soaking with either filtered deionized water or injection water until neutrality, measure conductivity.Blow dry the surface area using air with pressure of >=0.4MPa.

(2) Acid Cleaning: Soak in 5% Nitric Acid solution for more than 8 hours at 40 degrees; the temperature may increase slightly over this period. In the ultrasonic cleaning machine is best. After soaking with filtered deionized water or injection water rinsed inside and outside to neutral, side conductivity.

(3) organic contamination can be combined with surfactant cleaning, cellular debris contamination system combined with enzyme cleaning effect is more desirable (food and beverage can be cleaned with a high concentration of citric acid) .

(4) If there are conditions, combined with the best effect of ultrasonic cleaning machine.

Note: to often online backwash (online cleaning with pure compressed air or filtered liquid or clean water backwash), can reduce the number of times with the above methods of cleaning.

How Xubo controls the quality of metal sintered cartridges

1. Control the quality of raw materials: the quality of metal sintered cartridge is closely related to the quality of raw materials, so in the production process, the source and quality of raw materials should be strictly controlled, and raw materials of high quality and good consistency should be used as much as possible.

2. Control of process parameters: The quality of metal sintered cartridge is also closely related to the parameters of production process, including temperature, pressure, sintering time, etc. During the production process, these parameters should be gradually adjusted and optimized to ensure that the product quality can be guaranteed in each process.

3. Strict quality control: The product quality of metal sintered cartridge can be effectively controlled through a strict quality control process, including raw material acceptance, production process monitoring, finished product inspection and other links.

4. Strengthen management: Key processes should be operated in strict accordance with the work instructions to ensure the stability of quality, and it is also necessary to strengthen the training of operators and improve the level of production management to ensure the product quality of metal sintered cartridges.If you are interested in our products, please feel free to contact us sales@xuboti.com
