High-Precision Wire-Wound Filter Cartridge: Semiconductor Electronic Cleaning Solution and Photovoltaic Pure Water Filter Cartridge
Product Introduction
This High-Precision Wire-Wound Filter Cartridge is a professional high-end filtration component custom-engineered for the purification of semiconductor electronic cleaning solutions and photovoltaic pure water systems, crafted with high-purity electronic-grade polypropylene (PP) wire as the core raw material and adopting advanced micro-precision spiral winding technology with nanoscale pore size calibration. Tailored to the ultra-stringent cleanliness and water quality requirements of semiconductor chip manufacturing and photovoltaic cell production, it serves as a critical precision filtration barrier in the front-end and intermediate purification links of semiconductor electronic cleaning fluid circulation systems and photovoltaic pure water preparation lines. The all-electronic-grade PP structural design ensures absolute non-toxicity, low extractables, and excellent chemical compatibility with various semiconductor cleaning agents (such as SC-1, SC-2) and deionized pure water, with no material shedding, dissolution or secondary pollution to the filtered fluids. It efficiently removes trace fine particulate impurities and macromolecular colloids in the fluids, maintains the ultra-high purity of semiconductor cleaning solutions and photovoltaic pure water, prevents impurity-induced production defects such as wafer surface contamination, photovoltaic cell grid line breakage and low conversion efficiency, and protects the high-value precision production equipment in semiconductor and photovoltaic industries while ensuring the stability of mass production processes.
Filtration Precision
The High-Precision Wire-Wound Filter Cartridge is optimized for the ultra-high purity demand of semiconductor electronic cleaning solutions and photovoltaic pure water, with standard filtration precision grades covering 0.1 μm to 5 μm, including the core high-precision specifications of 0.1 μm, 0.22 μm, 0.45 μm, 1 μm and 5 μm for targeted interception of trace fine insoluble impurities of different particle sizes. Adopting a multi-layer gradient dense winding process with ultra-fine PP wire, the filter layer features a highly uniform and consistent pore size distribution without pinhole, crack or channeling defects, which can thoroughly remove trace metal oxide particles, silicon powder debris, colloidal precipitates, micro-polymer impurities and microbial flocs generated during the production and circulation of semiconductor cleaning solutions and photovoltaic pure water. This extreme-precision filtration performance ensures that the filtered fluids meet the SEMI F20 standard for semiconductor manufacturing and the ultra-pure water quality requirements of photovoltaic cell production (resistivity ≥18 MΩ·cm), fundamentally eliminating production quality defects caused by trace particulate impurities.
Flux
Benefiting from the optimized micro-precision spiral winding structure, high-permeability electronic-grade PP raw material and large effective filtration area design, this filter cartridge maintains stable and efficient flux performance under extreme high-precision filtration conditions, perfectly adapted to the continuous and stable fluid supply demand of semiconductor electronic cleaning solution circulation systems and photovoltaic pure water preparation lines. Under the standard operating conditions of 25℃ and 0.2MPa inlet pressure, the initial pure water flux of a single cartridge reaches 50-100 L/m²·h, and the actual stable working flux for the purification of semiconductor electronic cleaning solutions and photovoltaic pure water remains at 30-70 L/m²·h for a long time. Even in the continuous filtration of high-viscosity semiconductor cleaning agents and high-purity photovoltaic pure water, the flux attenuation rate is extremely low, which can ensure the unobstructed circulation of cleaning solutions and the continuous supply of pure water, and avoid the reduction of production efficiency caused by insufficient filtration flux in semiconductor and photovoltaic mass production lines.
Salt Rejection Rate
As a high-precision microfiltration component for the purification of semiconductor electronic cleaning solutions and photovoltaic pure water, this wire-wound filter cartridge is designed for the efficient interception of trace fine particulate impurities, macromolecular colloids and insoluble micro-pollutants, and does not have the ion separation and desalination function of reverse osmosis (RO), nanofiltration (NF) and other membrane components. Its salt rejection rate is 0%, which means it only retains insoluble micro-impurities in the fluids while allowing all soluble inorganic ions, small molecular weight semiconductor cleaning agent active ingredients and pure water molecules to pass through the filter layer smoothly. This characteristic is fully in line with the core demand of semiconductor and photovoltaic fluid purification, which only needs to remove insoluble particulate impurities without changing the chemical composition and ion concentration of the cleaning solution and pure water, and provides qualified ultra-pure fluids for the subsequent production processes of semiconductors and photovoltaics.
Pressure Drop
The product is specially designed with a low-pressure drop optimization structure for the extreme high-precision filtration scenarios of semiconductor electronic cleaning solutions and photovoltaic pure water, fully considering the pressure loss control requirements of high-precision fluid purification systems in high-tech industries. Under the rated working flux and standard temperature conditions, the initial pressure drop of a single filter cartridge is only 0.008-0.025 MPa, which minimizes the fluid flow resistance in the precision filtration link and effectively reduces the energy consumption of the circulation pump and water supply pump in semiconductor and photovoltaic production systems. During long-term continuous use, due to the uniform pore size distribution and high trace impurity-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 0.10 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 semiconductor cleaning solution circulation system and photovoltaic pure water preparation line, and avoid the impact of excessive pressure loss on the precision production equipment and production process stability.
Molecular Weight Cutoff (MWCO)
This High-Precision Wire-Wound Filter Cartridge has a precise and narrow molecular weight cutoff range of 30,000 to 150,000 Daltons, which is specially calibrated for the purification demand of semiconductor electronic cleaning solutions and photovoltaic pure water. It can effectively intercept macromolecular substances in the fluids such as colloidal silicon dioxide, macromolecular organic cleaning agent agglomerates, metal hydroxide macromolecular flocs and polymer micro-impurities that may cause contamination and damage to semiconductor wafers and photovoltaic cell wafers. The strict and accurate MWCO control ensures that small molecular weight inorganic ions, cleaning agent active molecules and pure water molecules pass through the filter layer smoothly while realizing the efficient interception of all harmful macromolecular insoluble impurities, and provides reliable molecular-level precision filtration protection for the semiconductor and photovoltaic production fluid systems.
Membrane Thickness
The high-precision PP wire-wound filter layer of this cartridge adopts a multi-layer gradient composite spiral winding design with a uniform total effective filter layer thickness of 80-150 μm, and the diameter of the ultra-fine electronic-grade PP wire is precisely controlled to 0.05-0.15 mm to ensure the consistency of the filter layer pore size and extreme filtration precision. The inner and outer sides of the filter layer are equipped with high-density, low-resistance and anti-shedding electronic-grade PP mesh protective layers with a thickness of 60-80 μm each, and the inner skeleton is a reinforced electronic-grade PP support structure with high rigidity, low extractables and excellent pressure resistance. The ultra-thin and uniform filter layer thickness design not only ensures the extreme high-precision filtration performance and sufficient mechanical strength of the filter cartridge, but also effectively reduces the fluid flow resistance and improves the permeability of the filter layer. The electronic-grade PP raw material and ultra-precise winding process ensure that the filter layer has no fiber shedding, material dissolution or deformation in various semiconductor cleaning solutions and high-purity photovoltaic pure water for a long time, avoiding secondary pollution to the ultra-pure fluids and meeting the strictest purification requirements of semiconductor and photovoltaic high-tech production.
Replacement Cycle
Under the normal operating conditions of semiconductor electronic cleaning solution circulation systems and photovoltaic pure water preparation lines (fluid turbidity ≤0.05 NTU, 24-hour continuous stable filtration, regular routine integrity testing and mild backwashing with ultra-pure water), the recommended replacement cycle of this High-Precision Wire-Wound Filter Cartridge is 2-4 months. If the production load is high (such as mass production of 7nm/5nm semiconductor chips and high-efficiency PERC/HJT photovoltaic cells) or the fluid impurity content fluctuates abnormally due to production environment changes, the replacement cycle should be appropriately shortened to 1-2 months. In addition, when the pressure drop of the precision filtration link reaches the maximum allowable value of 0.10 MPa, or the filtration flux decreases significantly and cannot be restored after ultra-pure water backwashing, or the filter cartridge fails the integrity test, it should be replaced immediately to ensure the ultra-high purity of semiconductor cleaning solutions and photovoltaic pure water, and avoid the occurrence of high-value production defects caused by fluid impurity exceeding the standard.
