10-inch Wire-Wound Filter Cartridge: Electronic Factory Process Liquid Circulation Particle Removal Filter Cartridge
Product Introduction
This 10-inch Wire-Wound Filter Cartridge is a compact, high-performance professional filtration component custom-engineered for particle removal in process liquid circulation systems of electronic factories, manufactured with high-purity electronic-grade polypropylene (PP) wire as the core raw material and adopting advanced precision spiral winding technology with calibrated layer density for small-size cartridges. Tailored to the compact installation space and strict particle removal requirements of electronic factory process liquid circulation lines—including cleaning fluids, etching additives, photoresist diluents and cooling process liquids—it serves as a critical precision filtration barrier in small-flow, multi-node circulation systems of electronic manufacturing workshops. The all-electronic-grade PP structural design ensures low extractables, no material shedding, and excellent chemical compatibility with various electronic process liquids, eliminating secondary pollution to the circulating fluids. It efficiently removes micro and fine particulate impurities generated during liquid circulation and production processes, maintains the ultra-clean state of electronic factory process liquids, prevents particle-induced defects such as circuit short circuits, wafer contamination and component surface blemishes, and protects small-scale precision circulation equipment (e.g., micro-pumps, fine nozzles) while ensuring the stability of continuous electronic production processes. The standardized 10-inch compact design perfectly matches the universal small-size filter housings in electronic factories, realizing flexible and convenient filtration configuration for multi-point process liquid circulation.
Filtration Precision
The 10-inch Wire-Wound Filter Cartridge is optimized for the particle removal demand of electronic factory process liquid circulation, with standard filtration precision grades covering 0.5 μm to 50 μm, including the most commonly used specifications for electronic manufacturing of 0.5 μm, 1 μm, 5 μm, 10 μm and 20 μm, which can be targeted to intercept different particle size insoluble impurities in various process liquids. Adopting a uniform and dense spiral winding process with ultra-fine PP wire for the 10-inch small cartridge, the filter layer features a highly consistent pore size distribution without pinhole or channeling defects, thoroughly removing metal oxide particles, silicon powder debris, resin micro-particles, dust and colloidal precipitates from the circulating process liquids of electronic factories. This stable and precise filtration performance ensures that the process liquids in circulation meet the ultra-clean particle control standards of electronic manufacturing, fundamentally eliminating production quality defects of electronic components, PCBs and wafers caused by particulate impurities in process liquids.
Flux
Benefiting from the optimized 10-inch compact structural design, scientific spiral winding layout and high-permeability electronic-grade PP raw material, this filter cartridge exhibits excellent and stable flux performance under the working condition of small-flow process liquid circulation filtration in electronic factories. Under the standard operating conditions of 25℃ and 0.2MPa inlet pressure, the initial pure water flux of a single 10-inch cartridge reaches 60-120 L/m²·h, and the actual stable working flux for particle removal in electronic factory process liquid circulation remains at 40-80 L/m²·h for a long time. Even in the continuous circulation filtration of high-viscosity photoresist diluents and high-purity electronic cleaning fluids, the flux attenuation rate is extremely low, which can ensure the unobstructed circulation of small-flow process liquid lines in electronic workshops, and avoid the reduction of production efficiency caused by insufficient filtration flux in multi-node process liquid circulation systems.
Salt Rejection Rate
As a dedicated particle removal filtration component for electronic factory process liquid circulation, this 10-inch wire-wound filter cartridge is designed for the efficient interception of insoluble particulate impurities and macromolecular colloids in electronic process liquids, and does not have the ion separation and rejection function of reverse osmosis, nanofiltration and other desalination membrane components. Its salt rejection rate is 0%, which means it only retains insoluble solid particles and macromolecular colloids in the process liquids while allowing all soluble metal ions, chemical reagent active ingredients, small molecular weight organic solvents and water molecules to pass through the filter layer smoothly. This characteristic is fully in line with the core demand of electronic factory process liquid purification, which only needs to remove particulate impurities without changing the chemical composition, ion concentration and performance of the process liquids, effectively maintaining the stable physical and chemical properties of circulating process liquids and ensuring the normal progress of electronic manufacturing processes.
Pressure Drop
The product is specially designed with a low-pressure drop optimization structure for the small-flow process liquid circulation filtration of electronic factories, fully considering the pressure loss control requirements of compact circulation systems with micro-pumps and fine pipelines. Under the rated working flux and standard temperature conditions, the initial pressure drop of a single 10-inch filter cartridge is only 0.008-0.025 MPa, which minimizes the liquid flow resistance in the particle removal link of process liquid circulation and effectively reduces the energy consumption of micro-circulation pumps in electronic factory process systems. During long-term continuous use, due to the uniform pore size distribution and high particle-holding capacity of the electronic-grade PP wire-wound filter layer, the pressure drop of the cartridge rises slowly and linearly; the maximum allowable operating pressure drop is 0.12 MPa. When the system pressure drop reaches this value, replacement is recommended in a timely manner to ensure the normal operating pressure of the entire electronic factory process liquid circulation system, and avoid the impact of excessive pressure loss on the operation of micro-precision circulation equipment and the stability of process liquid supply.
Molecular Weight Cutoff (MWCO)
This 10-inch Wire-Wound Filter Cartridge has a precise molecular weight cutoff range of 40,000 to 200,000 Daltons, which is specially calibrated for the particle removal and macromolecular colloid interception demand of electronic factory process liquid circulation. It can effectively intercept macromolecular substances in the process liquids such as colloidal silicon dioxide, macromolecular resin agglomerates, metal hydroxide flocs and polymer additive micro-aggregates that may cause contamination and damage to electronic components and production equipment. The strict and reasonable MWCO control ensures that small molecular weight soluble ions, electronic chemical reagents and solvent molecules pass through the filter layer smoothly while realizing the efficient interception of all harmful macromolecular insoluble impurities, and provides reliable molecular-level particle removal protection for the electronic factory process liquid circulation system.
Membrane Thickness
The electronic-grade PP wire-wound filter layer of this 10-inch cartridge adopts a multi-layer composite spiral winding design with a uniform total effective filter layer thickness of 90-160 μm, and the diameter of the ultra-fine electronic-grade PP wire is precisely controlled to 0.08-0.2 mm to ensure the consistency of the filter layer pore size and filtration precision for the small-size cartridge. The inner and outer sides of the filter layer are equipped with high-density, low-resistance electronic-grade PP mesh protective layers with a thickness of 60-80 μm each, and the inner skeleton is a reinforced 10-inch special PP support structure with high rigidity, low extractables and excellent pressure resistance, adapted to the compact installation and working characteristics of small-size filter cartridges. The moderate and uniform filter layer thickness design not only ensures the high-precision particle removal performance and sufficient mechanical strength of the 10-inch cartridge, but also effectively reduces the fluid flow resistance and improves the permeability of the filter layer. The electronic-grade PP raw material and precise winding process ensure that the filter layer has no fiber shedding, material dissolution or deformation in various electronic process liquids for a long time, avoiding secondary pollution to the ultra-clean process liquids and meeting the strict particle removal requirements of electronic manufacturing.
Replacement Cycle
Under the normal operating conditions of electronic factory process liquid circulation systems (process liquid turbidity ≤0.5 NTU, particle content ≤10 pcs/mL, 24-hour continuous stable circulation filtration, regular mild backwashing with ultra-pure water), the recommended replacement cycle of this 10-inch Wire-Wound Filter Cartridge is 2-5 months. If the electronic production load is high (such as mass production of fine-pitch PCBs and microelectronic components) or the process liquid particle content exceeds the standard due to production environment dust or equipment wear, the replacement cycle should be appropriately shortened to 1-2 months. In addition, when the pressure drop of the process liquid circulation particle removal link reaches the maximum allowable value of 0.12 MPa, or the filtration flux decreases significantly and cannot be restored after ultra-pure water backwashing, the filter cartridge should be replaced immediately to ensure the ultra-clean state of electronic factory process liquids and avoid the occurrence of production defects caused by excessive particulate impurities in the process liquids.
