Bronze powder sintered filter cylinder tubes are devices used for filtering liquids or gases, typically made from bronze powder. These filters often possess a porous structure that filters impurities or solid particles through tiny pores, resulting in a purer flow of the liquid or gas passing through.

The manufacturing process of bronze powder sintered filter cartridges includes the following steps:

product processing steps

Raw material preparation

High-quality bronze powder is chosen as the raw material and screened and processed according to design requirements to ensure powder uniformity and purity.

Molding

Using molds or pressing techniques, the bronze powder is shaped into tubular or cylindrical filters.

Sintering

The molded bronze powder is subjected to high-temperature environments for solidification through sintering, causing the powder particles to bond and form a solid structure.

Treatment

Post-sintering, the filter cartridges may undergo surface treatment or other specialized processes to enhance their filtering performance or durability.

Applications

Bronze powder sintered filter tubes are versatile filtering materials widely applied across various fields. Initially, they serve as dispersing cooling materials in high-temperature environments. For instance, they are commonly used in aircraft engine cooling systems, where the demand for materials possessing excellent heat dissipation and high-temperature resistance is paramount. Sintered copper filter cores perfectly meet these requirements.

Moreover, they find extensive use in gas distribution and liquidized bed perforated plate materials. Used in the chemical industry for liquidized bed reactors, these perforated plate materials ensure even material distribution and sufficient contact within the reactor, thereby enhancing reaction efficiency and product purity.

Further applications include high-precision, high-reliability, and high-temperature filtration materials. For instance, in high-temperature gas filtration, sintered copper filter cores effectively eliminate minute particulate matter, ensuring that high-temperature gases remain clean after passing through the filter. This significantly contributes to enhancing process efficiency in industrial production.

Lastly, sintered copper filter cores are commonly found in high-pressure reverse flushing oil filters. These filters are utilized in hydraulic systems to filter hydraulic fluid through sintered copper filter cores, guaranteeing the cleanliness of working fluids and ensuring the long-term stable operation of internal system components.

FAQ

01.What is sintered porous metal?

Sintered powder is molded by a mold and heated to melt, controlling the gaps between particles to capture and retain smaller particles that would not otherwise stay outside the filter element. However, over time, the accumulation of fine particles can reduce the flow through the filter element. Copper powder sintered filter cores are used in shipping, maritime, pharmacies, food and beverage processing, petrochemicals, laboratories, and more.

02.Why use sintered porous copper powder as a filter core?

Sintered porous bronze filter cores are extremely robust, have high strength, uniform porosity, excellent corrosion resistance, and a self-supporting structure, providing both surface and depth filtration. They offer greater particle retention capability.

03.What is the process for manufacturing sintered porous bronze filters?

Copper powder sintered filter cores use an unpressurized sintering process. Unpressurized sintering is a form of powder metallurgy. Powder is poured into a mold and placed in a dedicated furnace. Precisely controlled sintering conditions fuse particles into a high-strength finished component with a porous structure.
