Supply of copper passivation green liquid (KM0417)

Copper environmental passivation solution (KM0417) Product Description K & copper environmental passivation solution KM0417 suitable for copper, brass and other copper-based products passivation can improve its corrosion resistance. It belongs to a new type of high-quality copper products Universal primary passivation. This product is an organic phosphate-based, corrosion inhibitor and add a small amount of high-quality polymer passivation accelerator compound, does not contain ingredients etching, non-toxic, slightly taste. With the current RoHS environmental standards, by passivating the product can effectively ensure the passivation process does not destroy the original color of the workpiece, does not change the workpiece size, and greatly improve the ability of resistance to salt spray of copper artifacts. Features and Benefits * required passivation time is short, and high efficiency. * Simple process operation, no special operating environment requirements, non-toxic and low corrosion, general plastic containers can be used, the device is easy to configure ? This process has stable performance, surface treatment consistent characteristics. Process by this product after the best available anti-neutral salt spray test 48 hours no rust * The product is widely used in passivation copper, brass and other copper-based products, application versatility · widely used in various passivation class copper, brass and other copper-based products, especially for small precision complex parts large passivation. Specifications and approved for use by the FDA method #Initial Please read the Material Safety Data MSDS instructions, no experience in the use of professional guidance for qualified small series production again. This product is a liquid at room temperature to use. · The workpiece surface clean and free of oil into the product in room temperature water for 5 minutes or more time, rinse with water, then soaked in pure water and drying to packaging from 1 to 3 minutes. Conventional processes treated object - degreasing - over water - passivation - rinse - bubble pure water - drying or dry Note: the process can increase or decrease the quality indicators of the test method according to the actual situation: Density: Absolute measurement Selected range 1.0-1.1 for precision gravity meter, the accuracy of ± 0.01 can be measured directly. Relative measurements put 25ml standard cylinder on the accuracy of ± 0.1g electronic scale one, and then poured into pure water to 25ml tick unchanged, recording a weight of A. The water drained and then into the same scale KM0417 solution weight was recorded as B, do so at least three times the data processing: measure the density ρ = B / A (g / ml) pH value: This product with an accuracy of ± 0.01 Precision Number pH meter can be measured directly. Bath maintenance in the passivation process, due to continuous consumption of the passivation liquid oxidant effect and carry workpiece material, pH value of the passivation solution with the production of these factors will vary, the standard solution pH of about 0.96, if Description solution acid number greater than 1.5 is low, under normal circumstances only the passivation groove additional KM0417 new solution to bring the pH of the bath to return to the target range in the process. Aging solution through our long-term studies failed to prove: the working fluid after long-term use, when the solution reached the limits of impurity content SO42-> 10g / L, Cu2 +> 0.5g / L, Cl-> 60mg / L, the passivation performance dramatically decreased. No matter how additional new solution, passivation quality testing are difficult to meet, then drained the bath should be replaced with new fluid. Kai Union? Passivation quality checks · sulfate titration test with 8gCuS04 + 500mLH20 + 2 ~ 3mLH2S04 surface model was added dropwise, keeping wet, if not occur within 6min precipitated copper is qualified. · Salt spray test in accordance with QQ-P-35B 5% NaCL solution requires continuous spray test, according to the length of time to identify rust passivation film The quality of health and safety Statistics show that use of this product should be avoided in contact with skin and eyes. The contact should be rinsed with plenty of water, serious and timely hospital treatment. This product is in use must strictly follow the guidelines for material safety data sheets (MSDS) provided in addition to the designated purposes, the product should not be used for other purposes If disposing of used product, take care to protect the environment of wastewater treatment...: * This product is completely free of heavy metals, acid aqueous solution thus discharged after cleaning the surface, and to protect the environment, waste water collection pond will please the user, then with lime, sodium carbonate, sodium hydroxide and 7 to 8:00 PH value in discharge . · Wastewater treatment References: This liquid consumed amount of NaOH ≈155g / L Storage and packaging Ben during the storage, loading and unloading, the reference SH / TO164 be. This product does not burn, not explode, weak corrosive, environmentally friendly · 25Kg / barrel chemical drum, according to general chemical transport
