| electroplating main salt | nickel sulfamate is an excellent electroplating main salt, a dark green transparent liquid, easy to hydrolyze at high temperature or low pH value. Easily soluble in water, liquid ammonia, ethanol, slightly soluble in acetone, the aqueous solution is acidic, hygroscopic, deliquescent quickly in humid air. Slow weathering in dry air will lose four molecules of water when heated. When the temperature is higher than 110 degrees Celsius, it will begin to decompose and form basic salts. Continue to heat to produce a mixture of brown-black nickel trioxide and green nickel oxide. Because of its low internal stress, fast electroplating speed, high solubility, and no pollution, it has become a fast-developing main electroplating salt in the world in recent years. It has been widely used in precision electroplating, electronics, printed circuit board electroplating, Automobile, aerospace, weapons, coinage, metallurgy, nickel mesh, radio, nickel plating, metal coloring, nickel catalyst, ceramic brown pigment, colored aluminum alloy and other industries. Nickel sulfamate provides the nickel metal ions required for nickel plating and also acts as a conductive salt. The nickel salt content is high, and a higher cathode current density can be used, and the deposition speed is fast. It is often used for high-speed nickel plating. However, too high concentration will reduce the cathode polarization, the dispersion ability is poor, and the loss of the bath is large. The nickel salt content is low and the deposition speed is low, but the dispersion ability is very good, and the crystal fine and bright coating can be obtained. However, nickel sulfamate has poor stability and relatively high cost. |
| sulfamic acid | sulfamic acid is a sulfuric acid derivative with a bifunctional group of amino and sulfonic acid groups, which can chemically react with a variety of substances, The aqueous solution has the same strong acidity as hydrochloric acid and sulfuric acid, also called solid sulfuric acid, which has the characteristics of non-volatilization, no moisture absorption, no odor and minimal toxicity to human body. However, the skin cannot be in contact with sulfamic acid for a long time, let alone enter the eyes. It is stable at room temperature and can remain unchanged for several years. When the temperature reaches 209 ℃, it starts to decompose. Soluble in water and liquid ammonia, slightly soluble in methanol, insoluble in ethanol, ether, hydrocarbons and carbon disulfide. Although its aqueous solution is strongly acidic, it is less corrosive to metals than general inorganic acids, and has a slower effect on iron corrosion products. Some sodium chloride can be added to make it slowly produce hydrochloric acid, thereby effectively dissolving iron scale. It can also remove scale and corrosion products on the surface of equipment made of iron, steel, copper, stainless steel and other materials. It is the only acid that can be used for cleaning galvanized metal surfaces. When using sulfamic acid aqueous solution for cleaning, the temperature is generally controlled at no more than 66 ℃ (to prevent the decomposition of sulfamic acid), and the concentration does not exceed 10%. |
| use | electroplating for precision instruments used in electronic industry this product is mainly used for precision nickel plating, with the advantages of low internal stress and fast deposition speed of the coating. Mainly used for precision electroplating, its advantages are low internal stress of the coating and fast deposition speed. |
| production method | synthesis method reacts sulfamic acid with nickel hydroxide to generate nickel sulfamate, which is concentrated, crystallized, and centrifuged to obtain a finished product of nickel sulfamate. Its 2H2NSO3H Ni(OH)2 → Ni(NH2SO3)2 2H20 put 150 kg of amino sulfonic acid into a reaction kettle, and add hot distilled water to stir and dissolve. 100 kg of nickel carbonate was added and stirred to react in reflux state for several hours until the reaction without CO2 release ended. The reaction liquid is injected into the thin film evaporator for concentration, cooling and crystallization, filtering, centrifugal dehydration, and drying to obtain the finished product. |
