Stable Stainless Steel Powder Sintered Filter Disc

The stable stainless steel powder sintered filter disc is a porous structural material made by sintering stainless steel powder in a specific mold at high temperature, and are widely used in a variety of industrial filtration applications.

Physical and Chemical Properties

1. Porosity control

The porosity of the sintered discs can be adjusted by the powder particle size and the pressing pressure. Fine powders and high pressures usually produce structures with low porosity, and vice versa. Porosity directly affects the filtration efficiency and the ability of fluids to pass through.

2. Corrosion and heat resistance

Due to the use of high-quality stainless steel, these filter discs show excellent stability in acid, alkali and high temperature environments. For example, 316L filter discs can cope well with environments containing halogen ions.

3. Mechanical strength

Although the sintering process produces a porous structure, the stainless steel powder sintered filter discs still maintain a high mechanical strength, which enables them to withstand certain pressure differences and mechanical loads.

Manufacturing Process

1. Material selection

The stable stainless steel powder sintered filter discs are usually made of high-quality stainless steel materials 304 or 316L. These materials have good corrosion resistance and high temperature performance and can be used in a variety of harsh environments.

2. Powder preparation

Metal raw materials are processed into fine powders by methods such as atomization or mechanical grinding. The particle size, morphology and distribution of the powder directly affect the pore structure and strength of the final sintered part.

3. Pressing

The powder is placed in a mold with the desired shape, and the powder particles are rearranged and formed into a green body through mechanical or hydraulic pressure. There are a large number of gaps between the powder particles in the green body, which provides a basis for the formation of pores in the subsequent sintering step.

4. High temperature sintering

The green body is sintered at high temperature. The sintering temperature is usually lower than the melting point of the material, but sufficient to cause diffusion bonding between the powder particles. During the sintering process, the number of contact points between particles increases and the pore structure becomes fixed.

Parameters

Application Areas

1. Gas filtration

In the chemical, pharmaceutical and food processing industries, fine filtration of gases is often required to remove impurity particles. The stable stainless steel powder sintered filter discs are ideal for these occasions due to their excellent chemical stability and good mechanical strength.

2. Liquid filtration

In water treatment, petrochemical and laboratory applications, this type of filter disc is used to filter out suspended solids in liquids to ensure that the fluid quality meets standards.

3. High temperature applications

For systems that need to operate at high temperatures, such as certain chemical treatments and metallurgical processes, stainless steel powder sintered filter discs provide a high-temperature resistant and functionally stable filtration solution.

Selection Guide

1. Accuracy level

When selecting a filter disc, users need to consider the required filtration accuracy. Different powder particle sizes and process conditions can produce a variety of accuracy levels from coarse filtration to ultra-fine filtration.

2. Pressure difference and flow rate

The use environment determines the maximum working pressure and optimal working flow rate that the filter disc needs to withstand. Select the appropriate thickness and porosity according to specific needs to ensure efficient and economical filtration.
