Package (1) In 25kgs net multiple paper bags with one PE bag inner (2) In 25kgs net PE bags (3) In 25kgs net woven bags with two PE bags inner (4) In 1000kgs net big woven bags with one PE bag inner The above package is also with a pallet 1000kgs each. 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 ITEMS SPECIFICATIONS Appearance white crystalline salt Assay 99.0% w/w min Active oxygen 6.65% w/w min Chloride and chlorate(as CL) 0.005% w/w max Ammonia (NH4) 0.05% w/w max Manganese(Mn) 0.0001% w/w max Iron(Fe) 0.001% w/w max Heavy metals(as Pb) 0.001% w/w max Moisture 0.05% w/w max Decomposition of the product as supplied at above 65C Recommended storage temperature Normal Temperature Storage stability as from date of delivery 12 months
Honing refers to a set of stones (sticks) assembled on the honing head put pressure on the work-Piece along the radial, and through rotating and moving back and forth for precision honing machine. When honing high hardness and toughness materials, the Diamond /CBN Efficiency of honing stone( stick) is 3-75 times higher than that of ordinary abrasive stone, and the honing efficiency of ordinary materials is also improved about 10 times. since Diamond/CBN honing stone (stick) wear is less, the shape retention is better, therefore, the higher honing accuracy and economic effect can be obtained. Diamond honing stick is used to process hard and brittle materials, such as honing high carbon steel, cast iron, cemented, carbide, etc. honing stick mainly used for honing high strength alloy steel, tool steel, stainless steel heat-resistant alloy steel. Customized is OK
