Izithasiselo zokulawula ukulahlekelwa uketshezi ze-FC-610S
• I-FC-610S iyisengezo sokulahlekelwa uketshezi lwe-polymer lwesimende esisetshenziswa emithonjeni yamafutha esakhiwe nge-copolymerization ene-AMPS njenge-monomer eyinhloko kanye nezinye i-monomers ezilwa nosawoti. Inokumelana okuhle kokushisa nosawoti. Lo mkhiqizo unezele amaqembu okunzima ukuwafaka emanzini, okuthuthukisa kakhulu ukumelana nokushisa okuphezulu. Ukuba khona kwamaqembu amaningi anamathela kakhulu kuma-molecule, njenge-CONH2, SO3H, kanye ne-COOH, kubalulekile ekhonweni lama-molecule lokumelana nosawoti, ukugcina izinga lokushisa elihlala njalo, ukumunca amanzi mahhala, nokunciphisa ukulahleka kwamanzi, phakathi kwezinye izakhiwo.
• I-FC-610S inokuguquguquka okuhle futhi ingasetshenziswa ezinhlelweni ezahlukene ze-simende slurry. Ihambisana kahle nezinye izithasiselo.
• I-FC-610S ifaneleka ekushiseni okubanzi okunokumelana nokushisa okuphezulu okufika ku-230℃. Ngemva kokusetshenziswa, ukugeleza kohlelo lwe-slurry lwesimende kuhle, kuzinzile ngoketshezi olukhululekile oluncane futhi ngaphandle kokuhlehlisa isethi namandla akhula ngokushesha.
• I-FC-610S ifaneleka ekulungiseleleni ukungcola kwamanzi ahlanzekile/amanzi anosawoti
Izinkambu zikawoyela ezinokushisa okuphezulu zibhekene nezinselelo ezihlukile uma kukhulunywa ngokufakwa kwesimende emthonjeni. Enye yalezi zinselelo yinkinga yokulahleka koketshezi, okungenzeka lapho i-filtrate yodaka lokubhoboza ihlasela ukwakheka futhi ibangele ukwehla komthamo woketshezi. Ukuze sixazulule le nkinga, sithuthukise umshini wokunciphisa ukulahleka koketshezi okhethekile owenzelwe ngqo ukusetshenziswa ezinkambu zikawoyela ezinokushisa okuphezulu. I-FC-610S uhlobo lwesithasiselo sokulawula ukulahleka koketshezi futhi ifanele imakethe yaseMpumalanga Ephakathi.

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.
