1.Working priciple.
The processing is crushing --pulvering --separating , form whic the mixture of metal and non-metal is gained. Besides, separator combine with dust removl syesetm , due to different secifice gravity of materalis , non-metal such as dust , and grains which bears smaller graviry are taken away by dust removal sysetm, at the same time, the metal with lager gravity go into finished product recovery zone, thus the separation of metal and non-metal materials is achieved.
2.Advantage of pcb assembly
1).High recovery percent of metal , of which , the purity is up to 98%.
2).The price is only 1/5-1/3of that of the simaller product
3).The recovery rate of copper is about 3%-5% higher than other manufacturers of the sort
4).The unit consumption of energy to trest one ton of waste and unused pcb boards is only about 3/5 of that of domestic product alike
5).Easy operation, no polluction and noise, flexible for layout.

Storage
NPS(SPS) is not combustible but assists combustion materials due to release of oxygen.Provided it is stored under appropriate condition.It must be stored dry in closed containers and protected from direct sunlight,heat and humidity.Impurities such as dirt,rust or traces of metal and reductants may cause catalytic decomposition.The product as supplied or in solution needs to be handled with appropriate care.The eye,skin and clothes must be protected when working with NPS(SPS) as damp powder or aqueous solution has a bleaching and slightly corroding effect.
Application
Polymerization : Initiator for the emulsion or solution Polymerization of acrylic monomers,vinyl acetate,vinyl chloride etc.and for the emulsion co-polymerization of styrene,acrylonitrile,butadiene etc.
Metal treatment : Treatment of metal surfaces(e.g. in the manufacture of semiconductors;
cleaning and etching of printed circuits),activation of copper and aluminium surfaces.
Cosmetics : Essential component of bleaching formulations.
Paper : modification of starch,repulping of wet - strength paper.
Textile : Desizing agent and bleach activator - particularly for cold bleaching.(i.e.bleaching of Jeans).
Others :
- Chemical synthesis
- Water treatment(decontamination)
- Waste gas treatment,oxidative degradation of harmful substances(e.g.Hg)
- Disinfectant
