Can offer the following advanced products and technical services:
    1. Electroless nickel series concentrated solution: a nickel-phosphorus, nickel-copper-phosphorus, nickel, tungsten phosphorus three series of products. Solution stability, not lead, cadmium and other heavy metals, found ROSH directive, bath and convenient operation, can be output in phosphorus and high phosphorus coating, continuous production, you can rack can also be used for barrel plating; output stamping coating metal parts not covered by 4 micron gap, to meet the 96 hours of high temperature and high humidity storage test requirements. 25 micron high P amorphous coating is resistant to fuming nitric acid test for 24 hours.
    2. To provide a chemical copper concentrate and the surface treatment chemicals; non-formaldehyde electroless copper plating concentrate; copper surface, anti-discoloration agent, anti-discoloration can be treated by the 200 ° C hot air 4 hours does not change color, the natural place 6 month or more without color, without affecting the surface of the conductive properties of copper.
    3. Seawater corrosion-resistant heat exchanger: has obtained a patent license certificate; can be low temperature and small temperature difference heat transfer, import and export of temperature difference close to 1 ° C; plate corrosion resistance in seawater up to titanium level; the same thickness of plate heat capacity per unit area than the titanium alloys more than doubled. Can be used in chemical, wastewater treatment, marine, low-temperature waste heat utilization, aquaculture.
    4. Provide a full range of chemical nickel plating and nickel recycling waste water treatment technology and equipment; may be aging bath utilization, so that aging bath treatment continue to have effective treatment, the nickel content in waste water can be reduced to 0.23mg / l.
    5. Iron coated with nickel-phosphorus, nickel-copper-phosphorus, nickel-phosphorus series Tungsten powder; powder size: 20 nm, 50 nm, from 2 to 50 microns; chemical composition can be adjusted according to customer requirements. Typical ingredients: iron 75%, the rest of the nickel, phosphorus (copper, tungsten). Can replace titanium powder, stainless steel powder for powder metallurgy, casting, porous materials, gradient materials, the basic raw material.
    6. Gold package nickel, palladium nickel package products; can be used as conductive slurry, conductive ink or conductive films such as basic raw material. Can greatly improve the conductivity of nickel powder and high temperature oxidation resistance and reduce contact resistance, to prevent high-frequency breakdown.
    7. Metallizing technology and related products can be used as ignition, circuit breakers of the key components; ceramic cover part or all of nickel (or copper), can solder, ceramic cover 95% after nickel brazing withstood -55 ° C to 80 ° C high and low temperature impact.
    8. Ceramic structural parts and ceramic fiber coated with nickel, palladium, etc., can be used as a catalyst, ceramic shapes and palladium nickel content can be customized according to customer r
