Izithasiselo Zokulawula Ukulahlekelwa Koketshezi Oluphezulu lwe-FC-651S
• I-FC-651S inokuguquguquka okuhle futhi ingasetshenziswa ezinhlelweni ezahlukene ze-slurry yesimende. Ihambisana kahle nezinye izithasiselo. Ngokusekelwe ku-FC-650S, umkhiqizo uthuthukise ukumelana kwawo nosawoti futhi unomsebenzi ongcono wokumelana nosawoti.
• I-FC-651S ifaneleka ekushiseni okubanzi okunokumelana nokushisa okuphezulu okufika ku-230℃. Ukuqina kokumiswa kohlelo lwe-slurry lukasimende endaweni eshisa kakhulu kungcono kakhulu ngenxa yokwethula i-HA.
• I-FC-651S ingasetshenziswa yodwa. Umphumela uba ngcono uma isetshenziswa kanye ne-FC-631S/ FC-632S.
• Ilungele ukulungiswa kodaka lwamanzi amasha/lwamanzi 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 ingena ekwakhekeni futhi ibangele ukwehla komthamo woketshezi. Ukuze sixazulule le nkinga, sithuthukise umshini wokunciphisa ukulahleka koketshezi okhethekile owenzelwe ngqo ukusetshenziswa ezinkambu zikawoyela ezinokushisa okuphezulu. I-FC-651S iyisengezo sokulawula ukulahleka koketshezi olunokushisa okuphezulu futhi ifanele imakethe yaseCanada.

Izinto zokulawula ukulahleka koketshezi ziye zengezwa kuma-slurry esimende asemgodini kawoyela iminyaka engaphezu kwengu-20, futhi imboni yesimende namuhla iyavuma ukuthi ikhwalithi yemisebenzi yesimende ithuthuke kakhulu. Eqinisweni, kwamukelwa kabanzi ukuthi ukuphathwa kokulahlekelwa koketshezi okungafanele kungabangela ukwehluleka kokuqala kwesimende okubangelwa ukwanda kobuningi noma ukuvalwa kwe-annulus, nokuthi ukuhlasela kwesimende kokwakheka kungaba yingozi ekukhiqizweni. Izithasiselo zokulahlekelwa koketshezi zingakhulisa ukusebenza kahle kokubuyisela ngokuvimbela ukungcoliswa kongqimba kawoyela negesi kusuka kuketshezi oluhlungiwe ngaphezu kokulawula ngempumelelo ukulahleka koketshezi kwesimende.
