These are holes of different sizes that allow the flow of the fluid through the sintered nickel filters.

It also helps in blocking contaminants or impurities of varying sizes from passing through alongside the fluid.

·         Nickel Metal Mesh Layers

It also has a nickel wire mesh among the numerous layers that have pores that make up the sintered nickel filters.

You should know how the sintered nickel filters work in order to operate and maintain it well.

Here is a step-by-step process that you can follow when operating the sintered nickel filters.

1)      Introduction of the Fluid

Usually, you will have the sintered nickel filters in an enclosure where the fluid you intend to filter passes.

It often acts as a barrier within the system that will block the flow of the fluid passing through.

You must make sure that the sintered nickel filters are in the right place and covers the right space to prevent leakages.

With the presence of the O ring and gasket seal, you are sure of reducing any leakages through the system.

You will allow the fluids to flow from the source through the system while passing through the sintered nickel filters.

2)      Filtration Stage

As soon as it reaches the sintered nickel filters, there will be an interruption of flow.

The fluid will reduce speed and spread all over the sintered nickel filters.

The sintered nickel filters have holes in them which will allow the fluid to pass through.

Due to the great permeability, the fluid will comfortably flow through the sintered nickel filters.

The rate of flow is also perfect even though you will have to control the speed from the system control panel.

As the fluid flows through the tiny pore, impurities that cannot go through the pores also collect on one side.

This is the main purpose of having the sintered nickel filters as it controls the flow and filters the fluids.

The clean fluid will emerge on the opposite side of the sintered nickel filters to proceed with the entire process.

You will use sintered nickel filters specifically for the filtration of different fluid in different types of industries.

Here are some the main applications where sintered nickel filters come in handy.

It will prevent the essential nutrients in different foods and beverages form washing away in the fluid.

Sintered nickel filter

There are different sizes of the sintered nickel filters that you can choose from.

Implying that, you will decide on the size of the sintered nickel filters that you need for your applications.

You can have sintered nickel filters as small as the size of pin heads and as big as any equipment.

Generally, the size of sintered nickel filters does not have any limitations thus allowing you to dictate the size.

You should keenly concentrate on the flow rate, desired particle retention, and operating fluid among others during the designing process.

In addition to that, there are other key features that you have to pay very close attention to.

Here are the other design consideration features that you need to pay closer attention ti.

·         Micron Rating or Pore Sizes

This is the size of the pores which will release the fluid and block the contaminants from proceeding with the flow.

You can have a sintered nickel filter that is absolute 5 microns and will not allow entry of particles larger than 5 microns.

·         Pressure Drop

You should also look at the amount of pressure that the liquid will lose as it flows through the sintered nickel filters.

It is important to maintain the pressure drop as low as possible during the entire filtration process.

·         Temperature Range

You must also understand the temperature range of the sintered nickel filters to help in choosing the right materials.

You should choose materials that can withstand different temperature ranges to a maximum of 1200 degrees centigrade.

·         Tensile Strength

Your sintered nickel filters should also exhibit very high tensile strength properties to withstand very high pressure.

You have to understand the application requirements that will dictate how strong you have to make the nickel materials.

You will encounter quite a bit of a challenge in the cleaning process of the sintered nickel filters.

Sintered nickel filters are porous and will provide a challenge especially during the cleaning process.

Well, despite the cleaning challenge, you can simply clean the sintered nickel filters through the following procedure.

·         Ultrasonic Cleaning Process

Here, you will use an ultrasonic cleaning machine which will help in getting rid of the impurities from the filters.

You must take various precautions during the cleaning procedure and ensure that you adhere to time specifications.

You will also provide a flow of the fluid in the opposite direction of the original fluid flow when the filters are working.

This process will help in getting rid of the impurities stuck on the porous parts of the sintered nickel filters.

Alternatively, you can ensure that the direction of low comes from different directions thus disturbing the particles.

In the long run, the disturbance will eliminate the impurities from the pores within the sintered nickel filters.

Apart from that, you can also dip the sintered nickel filters in the cleaning solution thus getting rid of the debris.

This process works best in sintered nickel filters that have smaller pores and do not allow proper fluid flow.

The debris will eventually come off the sintered nickel filters through a series of dips and slow release of fluids.

You can manufacture sintered nickel filters using the same process of sintering just like other metal powders.

Here is a procedure that you can follow during the manufacturing process of the sintered nickel filters.

1.      Initiation of the Sintering Process.

You need to commence the sintering process by collecting all the relevant materials and machines.

In this case, you will require nickel powder materials as well as the tooling that will push the sintering process.

You can decide to use pure nickel powder or an alloy of different metals with nickel powders.

In the long run, the characteristics of the nickel filter will depend on the type of nickel powder you use.

2.      Blending or Mixing

You will add the nickel powder then continue the mixing process by adding other types of metal powders.

It is important to have a solid lubricant in the mix to reduce the friction between the powder and the tools.

In the end of the mixing process, you will get homogenous mixture of different metal powder including nickel.

It is also important to maintain strict dosing and controlling process to achieve the physical, mechanical, and chemical properties.

3.      Compaction

You will proceed with the compaction of the sintered nickel powder homogenous mixture.

It begins with the application of uniaxial pressure between 200 to 1500 Mpa.

You will apply different amounts of pressure depending on the density of the sintered nickel filters you desire.

The final product or green part is a compact material with a density of about 85 to 95%.

At this point, the green part assumes a particular shape with great mechanical properties for proper handling.

4.      Sintering Process

You will proceed with the sintering process inside a continuous furnace under particular environmental conditions.

Here, you will heat the compact green parts under controlled pressure below the melting point of the materials.

You will set the heat between 700 to 1300 degrees centigrade depending on the grade of nickel under use.

The high temperatures will create proper bonds between the particles of the green part on the sintered nickel filters.

Finally, you will get a product that has uniform mechanical properties which is the sintered nickel filters.
