Silver anti-discoloration agent silver liquid silver antioxidant protection liquid HF-801

HF-801 silver anti-discoloration agent I. Applications: HF-801 silver anti-discoloration agent is a neutral solution suitable for silver and silver-plated qualities against discoloration antioxidant protection agents, halogen-free, environmentally neutral product, treatment After silver and silver-plated surface forms a nanoscale protective layer to prevent oxidation discoloration of silver and silver pieces, silver pieces while maintaining optimum solderability, conductivity and brightness, high stability of the liquid product capacity wide operating range, is widely used in various types of silver handicrafts, electronic connectors, electrical accessories, silver jewelry accessories, electroplating and other industries. Second, the product advantages: 1, the product is non-toxic and non-irritating environmental protection, in line with EU environmental standards, simplicity in operation; 2, the product does not affect the electrical conductivity, does not affect the weldability, good sulfidation resistance and abrasion resistance . Third, the operation process: silver and silver pieces after cleaning or activation washing → HF-801 silver anti-discoloration agent → warm water soak a clean (about 40-50 degrees pure water) → clean water rinse → drying → packing four operating conditions: No. Project range Notes 1 HF-801 silver anti-discoloration agent 8-10% watered 2 Operating temperature 45 to 55 degrees to 50 degrees 3 soak for 3 to 6 minutes 5 minutes 4 plastic liquid container tank, PP / PVC, glass beaker unavailable metal groove 5 electric heating equipment, titanium Teflon heater five, management and maintenance: 1, the FDA must first shake well before, such as the storage temperature is below this product will be partially cured at 10 ℃, can Even barrel on the hot water, concentrated solution into liquid; 2, after a thorough cleaning before use sink to prevent contamination of the liquid, according to the ratio of preparation of a good bath, stir, after heated to about 55 ℃ can be used; 3, if antiblushing coolant or disable a little longer period of time, then there will be layered, will be back to normal after heating and stirring, usually 2-3% can be supplemented to maintain total bath was added HF-801 silver anti-discoloration agent liquid can be; 4, post-processing phenomenon marks or streaks, pre-treatment water is not clean, we should strengthen water quality before treatment; and poor oxidation resistance after treatment, the soaking time is too short, the temperature is not enough, at the same time maintain good liquid concentration; 5, the operating environment to maintain good ventilation, please do labor protection use. VI, packaging and storage: 20 kg / barrel, 1-year store it in a cool place.
