Izithasiselo zokulawula ukulahlekelwa uketshezi ze-FC-632S
• I-FC-632S inobuthi obukhulu besilinganiso esiphansi sokucheba, okungathuthukisa ngempumelelo ukuzinza kokumiswa kohlelo lwe-slurry lwesimende, kugcinwe ukugeleza kwe-slurry, kuvimbele ukuchitheka kwenhlabathi ngesikhathi esifanayo, futhi kube nokusebenza okuhle kokuvimbela igesi.
• I-FC-632S inokuguquguquka okuhle futhi ingasetshenziswa ezinhlelweni ezahlukene ze-slurry yesimende. Ihambisana kahle nezinye izithasiselo. Ngokusekelwe ku-FC-631S, umkhiqizo uthuthukise ukumelana kwawo nosawoti futhi ufaneleka kakhulu endaweni enosawoti.
• I-FC-632S ifaneleka ekushiseni okubanzi okunokumelana okuphezulu kokushisa okufika ku-230℃. Ngemva kokusetshenziswa, ukugeleza kohlelo lwe-slurry lukasimende kuhle, kuzinzile ngoketshezi olukhululekile oluncane futhi alunawo umthelela wokulibazisa futhi amandla okuqala ekushiseni okuphansi akhula ngokushesha. I-FC-632S ingasetshenziswa yodwa. Umphumela uba ngcono uma isetshenziswa kanye ne-FC-650S, efanelekile ekulungiseleleni i-slurry yamanzi 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-632S uhlobo lokulawula ukulahleka koketshezi futhi ifanele imakethe yaseRussia.

| Ingxenye ye-slurry yesamente: 100% grade G cement (Imelana ne-sulfate ephezulu)+44.0% amanzi ahlanzekile+0.6% FC-632S+0.5% i-ejenti yokuhlanza amafoam. | ||
Ngempela, ngokuvamile kuyavunywa ngokucacile ukuthi ukuntuleka kokulawula ukulahlekelwa uketshezi kungaba yimbangela yokwehluleka kokuqala kokufaka usimende, ngenxa yokwanda kobuningi noma ukuvalwa kwe-annulus nokuthi ukuhlasela kokwakheka yi-cement filtrate kungaba yingozi ekukhiqizweni.
