FC-620S Izithasiselo zokulawula ukulahleka koketshezi
• I-FC-620S iyisengezo sokulahlekelwa uketshezi lwe-polymerngosimende osetshenziswa kukahle amafuthafuthi yakhiwe yi-copolymerization ngeAMPSnjengokuyinhlokoi-monomer enezinga lokushisa elihle nokumelana nosawotifuthi ngokuhambisana nokunye okulwa nosawotimonomers.Iama-molecule aqukethe inani elikhulu lamaqembu akhanga kakhulu afana - CONH2, - SO3H, - COOH, adlalayosindima ebalulekile ekuphikiseni usawoti, ukumelana nokushisa, ukumuncwa kwamanzi amahhala, ukunciphisa ukulahlekelwa kwamanzi, njll.
• I-FC-620S ifanele izinga lokushisa elibanzingeukumelana nokushisa okuphezulu kufika ku-150 ℃.Ngemuva kokusetshenziswa, i-uketshezi lwesistimu ye-cement slurryyinhle, izinzile ngoketshezi olungakhululekile futhi alunasethi yokuhlehlisa futhi amandla akhula ngokushesha.
•FI-C-620Sisilungele izinhlobonhlobo zezinhlelo ze-cement ze-cement zamanzi olwandle.Inokuhambisana okuhle nezinye izithasiselo.
•FI-C-620S inokuhlakazeka okuqinile, ikakhulukazi ilungele amasistimu odaka lukasimende wamanzi amasha anokuqukethwe okuqinile okuphakeme noma izinto ezisezingeni eliphezulu eziphakeme kakhulu.
Amasimu kawoyela anezinga lokushisa eliphezulu abhekana nesethi eyingqayizivele yezinselelo uma kuziwa ekufakweni kukasimende kahle.Enye yalezi zinselele indaba yokulahlekelwa uketshezi, okungenzeka lapho i-filtrate yodaka lokumba ihlasela ukwakheka futhi ibangele ukuncipha kwevolumu yoketshezi.Ukuxazulula le nkinga, senze isinciphisi esikhethekile sokulahlekelwa uketshezi esiklanyelwe ukusetshenziswa ezindaweni zikawoyela ezinezinga lokushisa eliphezulu.

Sekuyiminyaka engaphezu kwengu-20, ama-ejenti okulawula ukulahlekelwa uketshezi aye engezwa ezidakamizweni zikasimende zomthombo kawoyela futhi manje sekuyabonakala embonini ukuthi izinga lemisebenzi yokusamende selithuthuke kakhulu.Ngempela, ngokuvamile kuvunywa ngokucacile ukuthi ukuntuleka kokulawula ukulahlekelwa uketshezi kungase kube nomthelela ekuhlulekeni kokuqala kukasimende, ngenxa yokwanda okukhulu kokuminyana noma ibhuloho le-annulus kanye nokuthi ukuhlasela kokwakheka ngokuhlunga usimende kungase kube yingozi ekukhiqizeni.Isengezo sokulahlekelwa uketshezi asikwazi nje ukulawula ngempumelelo ukulahlekelwa uketshezi lukasimende oludaka, kodwa futhi sivimbele ungqimba lwamafutha negesi ekungcolisweni uketshezi oluhlungiwe futhi ngaleyo ndlela kwandise ukusebenza kahle kokululama.
