Product Description

QY200 is a hydrophilic fumed silica with a specific surface area of 200m2/g, It is a kind of high purity white colloidal powder.Using the chlorosilane burning in hydrogen and oxygen flame at high temperature to get fumed silica (also named carbon black) is a white, non-toxic, tasteless, amorphous inorganic chemical product. By adjusting the technological conditions, QUNYUE enterprise production of the original size 7—40nanometers,with a specific surface area between 70---400m2/g.Because of its small particle size ?bigger surface area ?more activate surface characteristic ,in rubber ?coating?adhesive?paint?printing ink ?plastic?cosmetics as well as agriculture?medicine and other fields has the widespread application, to have a good reinforcement?thickening?absorbing the transparence?anti-UV?sterilization and so on Technical date BET surface area 200±20m2/g GB/T 10722 PH 3.6-4.5 GB/T 1717 Loss on drying(2h 105?) =1.5% GB/T 5211.3 Loss on ignition(2h 1000?, base on material dried for 2h 105?) =2.5% GB/T 20020 Sieve residue(45µm) =0.05% GB/T 5211.14 Tamped density(base on material dried for 2h 105?) 25-60g/L GB/T 5211.4 Silica content(base on ignited material) =99.8% GB/T 20020 Carbon content(base on material dried for 2h 105?) =0.2% GB/T 20020 Chloride content(base on material dried for 2h 105?) =0.025% Ferric oxide(base on material dried for 2h 105?) =0.003 Titanium oxide(base on material dried for 2h 105?) =0.03 Alumina(base on material dried for 2h 105?) =0.05
