Property: White crystal, easily absorbing moisture and be slaked in the air, easily soluble in water and alcohol. If heated above 200¡ãC, it will be suddenly decomposed with hydrogen phosphine released. Moreover, it is a good strong reducer, and contacted with oxidizing agent, it can be exploded.
Uses:
1. Chemical plating agents: After being plated chemically, the metal surface have solid, corrosion-resistant, wear-resistant, even and compact alloy-plated layer. It can be widely applied to electronics, machines, petroleum, chemical, aviation, navigation, food, pharmaceutical etc.
2.It can add a metal layer on the surface of plastics, ceramics, glass, quartz etc.
3.Water treatment, and manufacture of various industrial corrosion preventing agent and scale inhibiting agent for oil fields.
4.Additive for food and industrial boiler water.
5.Acting as catalyst and stabilizing agent for chemical reactions.
6.Acting as antioxidant, anti-decolorizing agent, dispersing agent, as well as applicable to textile finishing and pharmaceuticals.
Propertiesú¦
Pearl-luster crystal or white crystal powder, hydroscopic and deliquescent; easily soluble in water, pearl-luster crystal or white crystal powder, hydroscopic and deliquescent; easily soluble in water, reducing agent.
Usesú¦
Mainly used as the reductant for chemical plating. A dense and uniform nickel phosphorus film can be obta-
Ined for both large equipment and tiny components, articles with complicated external shape of convex concave lines or internal wall of deep-hollows, the surface of non-metals such as plastic, ceramics, glass and etc, the film possess a good surface hardness and abrasion resistance.
The product can be widely used in electronics, aviation, mechanism, and petroleum fields. It can also be used to prepare various industrial water treat-
Ment agents, used as catalyst and stabilizer of chemical reactions, and also us-
Ed as interface activator m.W. Moderater and thermostablizer for synthetic re-
Sins and additive for foods, and etc.
