Dedicated to the filtration and purification of electroplating solution, process water and circulating water in electroplating production, it efficiently intercepts suspended solids, colloidal impurities, metal debris and other insoluble contaminants in the liquid medium, ensuring the cleanliness of electroplating solution and the stable operation of filter machines. As a high-quality replacement part, it solves the pain point of poor compatibility of non-standard filter cartridges, with easy installation and replacement, stable filtration performance and high cost performance. It is an indispensable core consumable for electroplating enterprises to maintain the normal operation of filter machines, improve electroplating product quality and reduce production maintenance costs, and is widely applicable to various electroplating production scenarios such as hardware electroplating, precision electronic component electroplating and plastic electroplating.
Filtration Precision
Calibrated for the universal compatibility of mainstream electroplating filter machines and the diversified filtration needs of electroplating production, the filtration precision of this replacement PP wire-wound filter cartridge covers a customizable and industry-standard range of 1 μm to 100 μm, with the most commonly used specifications for electroplating scenarios being 1 μm, 5 μm, 10 μm, 20 μm and 50 μm. The high-precision specifications (1 μm, 5 μm, 10 μm) are suitable for precision electroplating filter machines used in the production of electronic components, jewelry and precision hardware, effectively intercepting micro colloidal impurities and fine metal debris that affect the finish and uniformity of electroplating workpieces; the medium and low-precision specifications (20 μm, 50 μm) are applicable to general electroplating filter machines for hardware electroplating, zinc plating and nickel plating, removing large particulate impurities and sediment in electroplating solution to reduce the blockage of filter machine pipelines and nozzles. All precision grades adopt uniform gap winding technology, with stable interception efficiency, no precision attenuation during use, and can be perfectly matched with the corresponding precision gears of various electroplating filter machines to meet the differentiated filtration requirements of different electroplating processes and filter machine types.
Flux
The flux performance of this replacement PP wire-wound filter cartridge is optimized according to the rated flow parameters of mainstream universal electroplating filter machines on the market, ensuring perfect matching with the operating flow of filter machines without causing flux mismatch and filtration efficiency reduction. Under the standard operating conditions of 25℃ ambient temperature and 0.2MPa inlet pressure, the initial pure water flux is 8-35 L/min per 10 inches of cartridge length, and the flux specification is divided into multiple grades to adapt to small, medium and large flow electroplating filter machines respectively. For actual electroplating solution (with a viscosity of 1.0-1.5 mPa·s) in normal electroplating production, the stable operating flux is 5-28 L/min per 10 inches when matched with the corresponding filter machine. The flux attenuation rate of the cartridge is strictly controlled during use, and the flux remains stable in the middle and early stages of filtration, avoiding the reduction of the overall filtration efficiency of the filter machine caused by excessive flux drop due to impurity accumulation. At the same time, the flux design fully considers the parallel use characteristics of filter cartridges in large-flow electroplating filter machines, and multiple cartridges can be used in parallel without mutual interference, ensuring the total flow of the filter machine meets the production demand.
Salt Rejection Rate
As a physical filtration consumable based on the pore size interception principle, this replacement PP wire-wound filter cartridge is designed to remove insoluble solid impurities in electroplating solution and other media, and does not have the function of desalination, ion removal or separation of dissolved substances. Therefore, its salt rejection rate is 0%. It only intercepts suspended solids, colloids, metal debris and other insoluble contaminants in the electroplating solution passing through the filter machine, and will not retain the effective metal ions, electrolyte components, plating additives and other soluble substances required for electroplating production in the solution. This characteristic is crucial for the normal operation of electroplating production: it ensures that the chemical composition, ion concentration and performance of the electroplating solution remain unchanged after filtration, complies with the process requirements of electroplating production, and avoids the failure of electroplating workpieces caused by the loss of soluble effective components in the solution. At the same time, the 0% salt rejection rate makes the cartridge not affected by the salt content of the electroplating solution, and can be applied to the filtration of various types of electroplating solution such as acidic, alkaline and neutral electroplating solution.
Pressure Drop
The pressure drop design of this replacement PP wire-wound filter cartridge is fully matched with the rated working pressure of universal electroplating filter machines, to ensure that the filter machine operates in the optimal pressure range without additional load or pressure mismatch. Under standard working conditions and initial operation state (no impurity accumulation), the initial pressure drop is strictly controlled within 0.01-0.04 MPa, which is consistent with the pressure loss design of the original filter cartridge of mainstream electroplating filter machines. This low initial pressure drop ensures that the filter machine can operate at the rated pressure without increasing the working load of the filter machine’s water pump, reducing energy consumption and avoiding the damage of the water pump caused by excessive pressure. With the progress of filtration and the gradual accumulation of intercepted impurities in the filter layer, the pressure drop of the cartridge will increase steadily. The recommended maximum allowable pressure drop is 0.20 MPa, which is the critical pressure value for most electroplating filter machines to maintain stable operation. When the pressure drop reaches this value, the cartridge needs to be replaced in a timely manner, which not only ensures the filtration effect of the filter machine, but also prevents the filter machine from being shut down due to excessive pressure and affecting the normal progress of electroplating production.
Molecular Weight Cutoff (MWCO)
Combined with the filtration precision range, universal compatibility design and actual electroplating solution filtration demand of this replacement cartridge, the molecular weight cutoff (MWCO) is set at 100,000 – 800,000 Da, and the MWCO grade is matched with the filtration precision one by one to realize precise interception of impurities. The high-precision cartridge (1 μm, 5 μm) with MWCO of 100,000 – 300,000 Da can effectively intercept small molecular weight colloidal impurities and macromolecular particulate matter in precision electroplating solution, ensuring the high cleanliness of the solution; the medium and low-precision cartridge (20 μm, 50 μm) with MWCO of 500,000 – 800,000 Da is suitable for the interception of large molecular weight insoluble impurities in general electroplating solution. This graded MWCO design not only ensures the efficient removal of harmful impurities in the electroplating solution, but also allows the small molecular weight plating additives, metal ion complexes and other soluble effective components in the solution to pass through the filter layer smoothly, without causing unnecessary interception and loss. At the same time, the MWCO performance is stable during the service cycle of the cartridge, without attenuation, ensuring the consistent filtration effect of the electroplating filter machine.
Membrane Thickness
The filter layer (wound PP wire layer) thickness of this replacement PP wire-wound filter cartridge is designed as 3-12 mm with graded specifications, and the total wall thickness of the cartridge (including porous PP inner core, filter layer and outer protective layer) is 10-20 mm, which is fully consistent with the dimensional specifications of the original filter cartridge of mainstream electroplating filter machines to ensure perfect installation compatibility. The thin filter layer (3-5 mm) is matched with high-precision cartridges (1 μm, 5 μm), which ensures high filtration precision while maintaining the water permeability of the cartridge, avoiding excessive flow resistance caused by overly thick filter layer and affecting the operating flow of precision electroplating filter machines; the thickened filter layer (8-12 mm) is applied to medium and low-precision cartridges (20 μm, 50 μm), which provides a larger dirt-holding space, extends the service cycle and is suitable for the high impurity content working condition of general electroplating filter machines. The porous PP inner core with optimized thickness has high compressive strength and uniform water permeability, which provides a stable supporting structure for the filter layer, avoids the deformation or damage of the inner core under the working pressure of the filter machine, and ensures the overall structural stability of the cartridge. The standardized total wall thickness ensures that the cartridge can be perfectly inserted into the filter machine’s cartridge seat without loose installation or poor sealing, avoiding liquid short circuit and filtration failure.
Replacement Cycle
The replacement cycle of this replacement PP wire-wound filter cartridge is determined according to the operating conditions of electroplating filter machines, the turbidity of electroplating solution and the electroplating production load, with strong practicality and operability. Under conventional working conditions (8-24 hours of filter machine operation per day, electroplating solution turbidity <10 NTU, matching the rated flow and precision of the filter machine), the **recommended replacement cycle is 1-4 months**: the high-precision cartridges (1 μm, 5 μm) for precision electroplating have a replacement cycle of 1-2 months due to high filtration precision and fast impurity accumulation; the medium and low-precision cartridges (20 μm, 50 μm) for general electroplating have a longer replacement cycle of 2-4 months. If the electroplating production is in high-load operation (24-hour continuous operation of the filter machine), or the turbidity of the electroplating solution is high (>10 NTU), the replacement cycle of all specifications of cartridges will be shortened to 2-6 weeks. In addition, the replacement cycle needs to be adjusted according to the actual operating parameters of the filter machine: if the pressure drop of the filter machine system reaches the recommended maximum value of 0.20 MPa in advance, or the filtration effect is significantly reduced (the electroplating solution has obvious impurities, and the electroplating workpiece has defects such as pinholes and rough surface), the cartridge should be replaced immediately regardless of the operating time. Timely replacement of the cartridge can effectively maintain the filtration efficiency of the filter machine, protect the internal components of the filter machine and ensure the stable quality of electroplating products.
