Izithasiselo Zokulawula Ukulahlekelwa Uketshezi ze-FC-605S
• I-FC-605S iyisengezo sokulahlekelwa uketshezi lwe-polymer lwesimende esisetshenziswa emthonjeni wamafutha futhi sakhiwe yi-copolymerization ene-AMPS njenge-monomer eyinhloko enokumelana okuhle kokushisa nosawoti kanye nokuhlanganiswa namanye ama-monomer alwa nosawoti. Ama-molecule aqukethe inani elikhulu lamaqembu anamathela kakhulu njenge-CONH2, - SO3H, - COOH, edlala indima ebalulekile ekumelaneni nosawoti, ukumelana nokushisa, ukumuncwa kwamanzi mahhala, ukunciphisa ukulahleka kwamanzi, njll.
• I-FC-605S inokuguquguquka okuhle futhi ingasetshenziswa ezinhlelweni ezahlukene ze-slurry yesimende. Ihambisana kahle nezinye izithasiselo futhi idlala indima ekukhuthazeni i-viscosity kanye ne-suspension ngenxa yesisindo esikhulu sama-molecule.
• I-FC-605S ifaneleka ekushiseni okubanzi okunokumelana nokushisa okuphezulu okufika ku-180℃. Ngemva kokusetshenziswa, ukugeleza kohlelo lwe-slurry lukasimende kuhle, kuzinzile ngoketshezi olukhululekile oluncane futhi ngaphandle kokuhlehlisa isethi namandla akhula ngokushesha.
• I-FC-605S ifaneleka ekulungiseleleni ukungcola kwamanzi ahlanzekile/amanzi anosawoti.
I-Foring Chemical FLCA iyisengezo sokulahlekelwa uketshezi lwe-polymeric esingabizi kakhulu esenzelwe ukunciphisa ukulahlekelwa uketshezi oluphezulu olunomfutho ophezulu (HTHP) olusebenza kahle ezimweni nasezidingweni ezahlukene, njengamazinga okushisa aphezulu kanye nokugcwala kukasawoti ophezulu. I-FC-605S iyisisombululo esithembekile nesisebenzayo sokubhekana nokulahlekelwa uketshezi ngesikhathi sokufakwa kwesimende ensimini kawoyela.

Sekuyiminyaka engaphezu kwengu-20, izinto zokulawula ukulahlekelwa uketshezi ziye zengezwa ezitsheni zesimende ezisebenzisa uwoyela futhi manje sekuyaziwa embonini ukuthi ikhwalithi yemisebenzi yokufaka usimende ithuthuke kakhulu. Ngempela, ngokuvamile kuyavunywa ngokucacile ukuthi ukuntuleka kokulawulwa kokulahlekelwa uketshezi kungaba yimbangela yokwehluleka kokuqala kokufaka usimende, ngenxa yokwanda kobuningi noma ukuvalwa kwe-annulus nokuthi ukuhlasela kokwakheka yi-cement filtrate kungaba yingozi ekukhiqizweni. Isengezo sokulahlekelwa uketshezi asikwazi nje ukulawula ngempumelelo ukulahlekelwa uketshezi kwesimende, kodwa futhi sivimbele ungqimba lukawoyela negesi ekungcolisweni uketshezi oluhlungiwe futhi ngaleyo ndlela kwandise ukusebenza kahle kokubuyisela esimweni saso.
