Izithasiselo Zokulawula Ukulahlekelwa Koketshezi Oluphezulu lwe-FC-633S
• I-FC-633S ine-viscosity ephezulu yesilinganiso esiphansi sokucheba, engathuthukisa ngempumelelo ukuzinza kokumiswa kohlelo lwe-slurry lukasimende, igcine ukugeleza kwe-slurry, ivimbele ukuchitheka kwenhlabathi ngasikhathi sinye, inokusebenza okuhle kokumelana nosawoti, kodwa ayinawo umsebenzi wokulwa nokushintsha kwegesi ngenxa yokushintsha kweqembu elisebenzayo.
• I-FC-633S inokuguquguquka okuhle futhi ingasetshenziswa ezinhlelweni ezahlukene ze-simende slurry. Ihambisana kahle nezinye izithasiselo.
• I-FC-633S ifanelekela izinga lokushisa elibanzi elinokumelana nokushisa okuphezulu okufika ku-230℃. Ngemva kokusetshenziswa, ukugeleza kohlelo lwe-slurry lukasimende kuhle, kuzinzile ngoketshezi olukhululekile oluncane futhi aludingi ukulibaziseka futhi amandla okuqala ekushiseni okuphansi akhula ngokushesha. Ifanelekela ukulungiselela 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-633S iyisengezo sokulawula ukulahleka koketshezi olunokushisa okuphezulu futhi ifanele imakethe yaseNyakatho Melika.

Ama-ejenti okulawula ukulahleka koketshezi asetshenziswe kuma-slurry esimende asemgodini kawoyela iminyaka engaphezu kwengu-20, futhi imboni yokufaka usimende isiqaphele ukuthuthuka okukhulu kwekhwalithi yamaphrojekthi okufaka usimende. Eqinisweni, kuyamukelwa kahle ukuthi ukuntuleka kokuphathwa kokulahlekelwa koketshezi kungaba yimbangela yokwehluleka kokuqala kokufaka usimende ngenxa yokwanda kobuningi ngokweqile noma ukuvalwa kwe-annulus, nokuthi ukuhlasela kwe-cement filtrate kokwakheka kungase kube yingozi emkhiqizweni. Izithasiselo zokulahlekelwa koketshezi zingasiza i-slurry yesimende ukuthi ilulame kahle ngokuvimbela ukungcoliswa kongqimba kawoyela negesi kanye nokulawula ngempumelelo ukulahleka koketshezi kwesimende.
