Benefits of Sodium Hypophosphite for Skin.

China factory supply Sodium Hypophosphite powder 99% purity Sodium Hypophosphite is mainly used as a preservative and antioxidant in the food industry. Sodium hypophosphite is not a dangerous substance, nor a hazardous chemical. It will only decompose into harmful gases at high temperatures. It is usually non-toxic, non-flammable, and non-corrosive.

Uses of Sodium Hypophosphite.

For large equipment and small objects that cannot be electroplated; objects with complex shapes that require high precision and concave and convex patterns; objects with deep hole inner walls that require high surface hardness and wear resistance; metallization of non-metallic materials such as plastics, ceramics, glass, quartz, etc., to obtain a dense and uniform nickel-phosphorus coating that is better than electroplating.

Widely used in electronics, aviation, machinery, petroleum and other industries. It can also be used to synthesize various water treatment agents, catalysts and stabilizers for chemical reactions, resin interfacial activators, molecular weight regulators, heat stabilizers and food additives.

Application of Sodium Hypophosphite in Electroplating.

‌Chemical nickel plating‌: Sodium hypophosphite is a commonly used reducing agent in the process of chemical nickel plating. It can combine with nickel to form a chelate and control the pH value, thereby improving the surface performance and finish of the nickel-plated product. Sodium hypophosphite as a reducing agent has the advantages of low redox potential, stable plating solution, and low cost, so it is widely used.

‌Chemical copper plating‌: When using sodium hypophosphite as a reducing agent for chemical copper plating, it is usually necessary to add some nickel ions as a catalyst. This can improve the conductivity and ductility of the copper plating layer. For example, iron sulfate can be used as a catalyst to carry out chemical copper plating with sodium hypophosphite.

‌Chemical tin plating‌: Sodium hypophosphite is also a commonly used reducing agent in chemical tin plating. The wastewater treatment effect produced by it is good, and sodium hypophosphite is low in price, stable in nature, and has no toxic side effects, which makes it widely used in chemical tin plating.

Chemical properties of sodium hypophosphite.

‌Solubility‌: Sodium hypophosphite is easily soluble in water and ethylene glycol. In 100ml of water, the solubility is 100g at 25℃, and the solubility increases to 667g at 100℃.

‌Thermal stability‌: Sodium hypophosphite will decompose when heated to produce phosphine, phosphorus, phosphites and phosphates. It will decompose rapidly above 200℃ and may release self-igniting toxic phosphine gas.

‌Reducibility‌: Sodium hypophosphite has strong reducing properties and can be used to reduce salts of gold, silver, mercury, nickel, chromium, cobalt, etc. to a metallic state.

‌Reaction with other compounds‌: Sodium hypophosphite reacts with sodium hydroxide to produce sodium phosphite and hydrogen; it is relatively stable in a dry state, but it will explode when mixed with potassium chlorate or other oxidants
