Small Precision PP Wire-Wound Filter Cartridge for Electroplating Solution Treatment
Product Introduction
This small precision PP wire-wound filter cartridge is a professional water treatment component engineered with high-purity polypropylene (PP) as the core raw material, adopting advanced micro-winding processing technology. Its compact structural design combines the advantages of high filtration accuracy and excellent dirt-holding capacity, and it is specially optimized for the complex composition of electroplating solution. The cartridge is dedicated to effectively intercepting suspended solids and colloidal impurities in electroplating solution without introducing any secondary pollutants to the plating solution system, ensuring the cleanliness and stability of the electroplating solution, and further improving the quality of electroplating workpieces. It is a cost-effective and reliable filtration solution for electroplating production lines, suitable for small-flow and high-precision filtration scenarios in electroplating workshops.
Filtration Precision
The filtration precision of this PP wire-wound filter cartridge is precisely calibrated for electroplating solution treatment needs, with the core precision range of 1 μm to 50 μm available for customized selection. For the removal of fine colloidal impurities and micro suspended solids in electroplating solution, the commonly used precision specifications include 1 μm, 5 μm, 10 μm and 20 μm, which can accurately intercept impurities of corresponding particle sizes according to the process requirements of different electroplating types (such as copper plating, nickel plating, chrome plating), and meet the strict cleanliness standards of electroplating solution in precision electroplating production.
Flux
Under the standard operating condition of 25℃ and 0.2MPa inlet pressure, the initial pure water flux of this small precision PP wire-wound filter cartridge is 8-20 L/min per 10 inches of cartridge length. For electroplating solution (with a viscosity of 1.0-1.5 mPa·s), the actual operating flux is adjusted to 5-15 L/min per 10 inches, which is matched with the small-flow filtration characteristics of electroplating solution circulation and single-tank treatment. The flux remains stable in the early and middle stages of filtration, and the attenuation rate is low, avoiding the reduction of production efficiency caused by excessive flux drop due to impurity accumulation in a short time.
Salt Rejection Rate
As a deep filtration filter cartridge based on physical interception principle, this PP wire-wound filter cartridge is not designed for desalination and ion removal, so its salt rejection rate is 0%. It only targets solid phase impurities such as suspended solids and colloids in electroplating solution, and will not intercept the effective metal ions, electrolyte components and additives in the plating solution, ensuring that the chemical composition and concentration of the electroplating solution remain unchanged after filtration, which is in line with the normal production requirements of electroplating processes.
Pressure Drop
The initial pressure drop of the cartridge under standard working conditions is controlled within 0.01-0.03 MPa, which means low energy consumption in the initial stage of operation and no additional load on the electroplating solution circulation pump. With the progress of filtration and the gradual accumulation of intercepted impurities in the cartridge, the pressure drop will increase continuously. When the pressure drop reaches the recommended maximum value of 0.15 MPa, the cartridge needs to be cleaned or replaced in time to ensure the normal filtration effect and avoid the damage of the cartridge caused by excessive pressure.
Molecular Weight Cutoff (MWCO)
Combined with the filtration precision and structural characteristics of the PP wire-wound filter cartridge, its molecular weight cutoff is set at 100,000-500,000 Da. This MWCO range is specially matched with the colloidal impurities in electroplating solution, which can effectively intercept the colloidal particles with corresponding molecular weight in the plating solution, while allowing the small molecular weight effective components (such as metal ion complexes, small molecular additives) in the electroplating solution to pass through smoothly, realizing the precise separation of impurities and effective components in the electroplating solution.
Membrane Thickness
The filter layer (wound PP wire layer) thickness of this small precision PP wire-wound filter cartridge is 3-8 mm, and the total wall thickness of the cartridge is 10-15 mm (including the PP inner core). The optimized thickness design of the filter layer ensures sufficient dirt-holding space on the premise of ensuring high filtration precision, which can extend the service cycle of the cartridge. At the same time, the moderate total wall thickness maintains the compactness of the cartridge structure, making it suitable for installation and use in small-size filter housings of electroplating production lines with limited installation space.
Replacement Cycle
The recommended replacement cycle of the cartridge is 1-3 months under the conventional electroplating production working condition (8-12 hours of continuous operation per day, electroplating solution turbidity <5 NTU). If the electroplating solution has high turbidity, or the production line is in continuous 24-hour operation, the replacement cycle will be shortened to 2-4 weeks. In addition, if the pressure drop of the filtration system reaches 0.15 MPa in advance, or the filtration effect is significantly reduced (the turbidity of the filtered electroplating solution exceeds the process standard), the cartridge should be replaced immediately regardless of the operating time to ensure the stability of the electroplating production process.
