Sintered Filter Cleaning in the Plastics Industry

Sintered filters are a type of filter made by compacting and sintering metal or plastic particles under high temperature and pressure. This process creates a porous material with a uniform structure that allows fluids to pass through while trapping solids and other particles.

Commonly used in the plastics and recycling industries, they offer a high level of filtration efficiency and can withstand high temperatures and harsh chemicals. 

Here are some specific ways sintered filters are used:

• Blow Moulding: Sintered filters are also used in blow molding machines to remove contaminants fromthe air system before it is used to form the shape of the item being moulded. They help ensure that the finished product is free from defects and impurities.
• Filtration: Sintered filters can also be used for general filtration purposes in the plastics and recycling industries. They are used to filter fluids and air, as well as lubricants, solvents, and gases used in the manufacturing process.

Why do Sintered Filters need Cleaning?

Sintered filters need cleaning to maintain their ability to remove particles and impurities from fluids and gases. If the filter becomes clogged with particulate matter, it can reduce the filter’s filtration efficiency and performance. Additionally, a clogged filter can cause a buildup of pressure in the system, which can lead to equipment damage or failure, as well as reduced production output. 

Regular cleaning can prevent this type of damage, saving businesses the cost of repairs or replacement. Cleaning also helps to maintain a consistent flow rate, ensuring that the equipment can operate at maximum efficiency and avoid reduced production output and can extend the lifespan of the filter by reducing wear and tear, allowing it to continue to perform effectively over time.

How can you Clean Sintered Filters?

There are several different methods that can be used to remove dirt, debris, and other buildup that can accumulate over time. These include:

• Pyrolysis burn-off: This involves subjecting the filter to high temperatures to burn off any organic contaminants. This method is typically used for filters used in high-temperature applications.
• Ultrasonic cleaning: This method involves placing the filter in a tank filled with a cleaning solution and subjecting it to high-frequency sound waves. This causes microscopic bubbles to form and implode, generating enough energy to dislodge contaminants from the filter surface.
• Chemical flushing: Using a chemical cleaning agent to dissolve or loosen the contaminants can be effective for certain types of filters. Chemicals such as acids and alkalis are used to break down the buildup, which is then flushed away. 

The Benefits of Cleaning Sintered Filters

Regular cleaning and maintenance of sintered filters is essential in maintaining filtration efficiency, preventing equipment damage, improving production output, extending filter lifespan, reducing maintenance costs, enhancing product quality, and improving safety in the workplace. Additionally, it can prevent equipment breakdown, downtime and save companies from unexpected costs!
