Fumedsilica CAS:7631-86-9

Silica e fumed e sebetsa e le sehlomathiso se feto-fetohang tlhahisong ea likhomaretsi, li-sealant, li-coatings, li-composite, li-plastiki le thepa ea rabara. Thepa ea eona e ikhethang, ho kenyeletsoa bohloeki bo phahameng, reactivity ea bokaholimo, le sebaka se phahameng sa bokaholimo, e etsa hore e be ea bohlokoa bakeng sa ho ntlafatsa thepa ea mechini, boitšoaro ba rheological, le litšobotsi tsa ts'ebetso ea lihlahisoa tse entsoeng. Mefuteng ea likhomaretsi le li-sealant, silica e fumed e sebetsa e le modifier ea rheology le thixotrope, e ntlafatsa khanyetso ea ho sag, taolo ea viscosity, le matla a ho khomarela. Ka ho fetola mahloriso a silica e fumed, bahlahisi ba ka fetola thepa ea phallo le boitšoaro ba ho fola ha likhomaretsi le li-sealant bakeng sa litlhoko tse ikhethileng tsa ts'ebeliso indastering ea kaho, ea likoloi le ea lifofane. Ho feta moo, silica e fumed e sebelisoa liphahlong le lipenteng ho fana ka litlamorao tse khahlanong le ho tsitsisa, ho thibela ho sag le ho matlafatsa. Boholo ba eona bo botle ba likaroloana le k'hemistri ea bokaholimo li ntlafatsa botšepehi ba filimi, ho hanyetsa ho ngoapa, le ho boloka khanya liphahlong tse sireletsang, lipente tsa meralo, le liphetho tse ikhethang, ho netefatsa ho tšoarella ha nako e telele le boipiletso ba botle. Mefuteng ea li-polymer, silica e fumed e sebetsa e le setlatsi se matlafatsang ho ntlafatsa matla a mechini, botsitso ba litekanyo, le khanyetso ea tšusumetso. Ha e kenyeletsoa ka har'a polasetiki, li-elastomer le thepa e kopaneng, e ntlafatsa ho satalla, ho hanyetsa ho khohlahala, le ho tsitsa ha boemo ba leholimo, e leng se etsang hore li lokele likarolo tsa sebopeho, likarolo tsa likoloi le li-enclosure tsa elektroniki tse hlokang litšobotsi tse phahameng tsa ts'ebetso. Ho feta moo, silica e fumed e sebelisoa e le thuso ea phallo le moemeli oa phallo e lokolohileng meriana, lihlahisoa tsa lijo le metsoako ea phofo. Bokhoni ba eona ba ho thibela ho koaheloa, ho ntlafatsa litšobotsi tsa phallo ea phofo, le ho laola ho monngoa ha mongobo ho ntlafatsa katleho ea ts'ebetso le boleng ba sehlahisoa li-granulation tsa meriana, li-supplement tsa lijo le lino tse phofshoana. Ho feta moo, silica e fumed e fumana lits'ebetso litlolong, lihlahisoa tsa tlhokomelo ea botho, le li-lubricant tsa indasteri e le moemeli oa ho teteana, moemeli oa ho emisa, le moemeli oa matting. Ho feto-fetoha ha eona ho laoleng sebopeho, viscosity, le thepa ea optical ho tlatsetsa ho etseng litlolo, li-lotion, mafura le maro a sebetsang ka botle bo lakatsehang le litšobotsi tsa ts'ebetso. Ka kakaretso, silica e fumed e bapala karolo ea bohlokoa liindastering tse fapaneng, e fana ka melemo ea mesebetsi e mengata e le motsoako o feto-fetohang bakeng sa ho ntlafatsa ts'ebetso ea sehlahisoa, botsitso le boleng lits'ebetsong tse fapaneng, e totobatsa bohlokoa ba eona saenseng ea thepa, tlhahiso le nts'etsopele ea sehlahisoa.
