Tlhaloso
Cas 109-99 Tetrahydrofunuran (Thf) ke nako e phahameng e sebelisoang haholo indastering e fapaneng e kang merimacecticals, polymers le bohlasoa. Th thf ea rona e atiloe ho barekisi ba tšepahalang Chaena 'me e le ba boleng bo phahameng. Ha e na mebala, e nang le lefu lena, e nang le pono e tlase, e e etsang hore e be moemeli ea loketseng lits'ebetso tse ngata. Ho feta moo, thf ea rona e theko ea motheo, e e etsa tharollo e theko e boima bakeng sa litlhoko tsa hau tsa solt.
Tetrahydrofuturan (thf) ke cyclic form form ea lik'hemik'hale (Ch₂) ₄o mme e sebelisoa hangata indastering ea indastering e fapaneng. Li-Cas 109-994 tsa th'9 li libisoa ho barekisi ba tšepahalang Chaena ebile ke ba boleng bo phahameng. Ke mokelikeli o se nang mebala, o tukang o nang le pono e tlase, o e etsa hore e be moemeli ea loketseng lits'ebetso tse ngata.
E 'ngoe ea melemo ea rona ea Thf ke boemo ba eona bo phahameng ba bohloeki, ka bohloeki bo tlase ba 99.9%. Boemo bo phahameng ba bohloeki bo tiisa hore thf ea rona e lokolohile ho litšila tse ka amang boleng ba lihlahisoa tsa hau. Ho feta moo, thf ea rona e na le sesosa se tlase sa metsi, se eketsang bohloeki ba sona.
Boithabiso ba rona bo boetse bo theko e boima, boa e etsa tharollo e sebetsang e le litšenyehelo tsa litlhoko tsa hau tsa solt. Sena se etsa hore e be khetho e ntle bakeng sa likhoebo tse shebang ho fokotsa litšenyehelo tsa bona ntle le ho sekisetsa boleng.
Mabapi le likopo, THF e sebelisoa haholo indastering ea meriana e le ea boithabiso le e le karolo ea lithethefatsi. E boetse e sebelisoa tlhahisong ea polytetramethylene ether glycol (ptmeg), e sebelisitsoeng ho etsa swindex le li-elastome tse ling. Ntle le moo, thf e sebelisoa e le solvent ho tlhahiso ea likotsi, lidhesa le tse hatisang li-inks.
E 'ngoe ea thepa e ikhethang ea thf ke bokhoni ba eona ba ho qhibiliha mefuta e fapaneng ea metsoako e mengata, ho kenyeletsoa li-polyvinyl chlonide (pvdf). Thepa ena e etsa hore thf solvent bakeng sa lits'ebetso tsa lits'ebetso tsa polymer, tse kang ho leleka polymer le ho leleka filimi.
Ha ho tluoa ho sebetsana le ho boloka ente ea rona ho fanoa ka liphutheloana tsa boleng bo phahameng ho netefatsa lipalangoang tse Supileng le polokelo. Ho bohlokoa ho tseba hore thf e ntle haholo ebile e lokela ho bolokoa sebakeng se pholileng, se nang le moea o futhumetseng hantle, se setle haholo le mehloli ea ho nyahlatsa.
Qetellong, CAS 109-99 THF ke boleng bo holimo, tlholisano ea tlholisano e theko e phahameng ea tlhophiso e lekanang le lits'ebetso tse fapaneng indastering e fapaneng. Boemo ba eona bo phahameng ba bohloeki, litaba tse tlase tsa metsi le bokhoni ba ho qhibilihisa metsoako e fapaneng ea manyolo ho etsa khetho e fapaneng le ea theko ea likhoebo tse hlokofatsang lits'ebetso tsa bona le ho fokotsa litšenyehelo. Ikheeleng le rona kajeno ho ithuta ho eketsehileng ka thf ea rona le kamoo e ka tsoelang khoebo ea hau.
