Sintering is a process that helps in
improving the properties of woven wire and is largely based on the diffusion
bonding of the molecules. It is also used for laminating several layers of wire
cloth resulting in the creation of useful and diversified permeable materials
many of which may not be used widely across different engineering communities.
Understanding
wintered wire mesh
The process of sintering can be
performed in the major types of wire meshes. One of the most prominent reasons
to carry out the process of sintering is to create a bond in the wires in all
those places where they cross together, and eliminates the opportunity of
medium migration. You must have heard about the varied applications of the sintered mesh where the wires run in
perpendicular directions. The way in which every point is securely fused so
that the small discs in the cloth can be easily punched without chances of
fraying makes it a widely accepted practice. It is commonly used in

Medical filtration processes
Applications
in filtration
To meet the challenging and diverse
applications during the process of filtration, the sintered meshes have found
wide usage. In this process, a specific range of meshes bond together under
pressure and heat. The process of filtration undergoes optimization due to the
unique and advantageous performance of each layer of mesh. The primary reason
to use this mesh is to obtain the finest level of filtration, and thanks to the
durable structure of the mesh for making the medium resistant to physical
loading.
Advantages
and properties of the sintered mesh
The process of sintering enhances the
process of filtration in several ways. You can take a quick glimpse of the
properties and benefits of sintering in the mesh.
§ It is resistant to thermal
and mechanical loading, and the structure is highly robust.
§ Has gained popularity due
to reduced downtime and eves for a long time.
§ Sintering results in the finest
size of the aperture and the pores are regularly distributed
§ The ability of backwashing
generates greater reliability in the perspective of backwashing pressure.
§ You can choose the flow
resistance and achieve high rates of flow
§ Obtaining a varied range
of combination is possible, and one can get up to a thousand layers.
§ The disk size can be
enhanced to a higher limit without welding
§ Easy to achieve
consistency in product quality due to a high level of corrosion resistance when
used with noble metals such as Hastelloy, stainless steel and Inconel
§ Reduces the loading of the
filter medium during pulsation.
Basic
advantages
The basic advantages of meshes that
are sintered are the following.
v Exhibits increased
mechanical strength and withstands high pressure
v Free from medium migration
as the fragments of wires are tightly bonded together
v Widely used by companies
involved in filter cleaning processes
v Constant filtration rating
with time
Other uses
Different layers of the mesh, when
bonded together, helps in achieving optimum stability and is equipped with
superior backwashing abilities and high flow rate. The use of sintering is
applicable in:
§ Liquid and gas filtration
§ Applications of
biotechnology
§ Filtration of liquids with
high viscosity
§ Aeration components and
fluidized beds
It is an ideal solution for attaining
filtration under the harshest and high pressure conditions.
