Izithasiselo zokulawula ukulahlekelwa uketshezi ze-FC-650S
• I-FC-650S iyisengezo sokulahlekelwa uketshezi lwe-polymer lwesimende esisetshenziswa emthonjeni wamafutha futhi sakhiwe yi-copolymerization ene-AMPS/NN/HA njenge-monomer eyinhloko enokumelana okuhle kokushisa nosawoti kanye nokuhlanganiswa namanye ama-monomer alwa nosawoti. Ama-molecule aqukethe inani elikhulu lamaqembu anamathelayo kakhulu njenge-CONH2, - SO3H, - COOH, edlala indima ebalulekile ekumelaneni nosawoti, ukumelana nokushisa, ukumuncwa kwamanzi mahhala, ukunciphisa ukulahleka kwamanzi, njll.
• I-FC-650S inokuguquguquka okuhle futhi ingasetshenziswa ezinhlelweni ezahlukene ze-simende slurry. Ihambisana kahle nezinye izithasiselo.
• I-FC-650S ifaneleka ekushiseni okubanzi okunokumelana nokushisa okuphezulu okufika ku-230℃. Isebenza kahle ekuzinzeni kokumiswa endaweni eshisa kakhulu ngenxa yokungenisa i-humic acid.
• I-FC-650S 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.

| Ingxenye ye-slurry yesamente: 100% grade G cement (Imelana ne-sulfate ephezulu)+44.0% amanzi ahlanzekile+0.9% FC-650S+0.5% i-ejenti yokuhlanza amafoam. | ||
Ama-ejenti okulawula ukulahleka koketshezi asetshenziswe kuma-slurry esimende asemgodini kawoyela iminyaka engaphezu kwengu-20, futhi imboni isiyaqonda ukuthi lokhu kuye kwathuthukisa kakhulu ikhwalithi yamaphrojekthi okufaka usimende. Eqinisweni, kuyamukelwa kahle ukuthi ukuntuleka kokuphathwa kokulahlekelwa koketshezi kungaba yimbangela yokwehluleka kokuqala kokufaka usimende ngenxa yokwanda kobuningi noma ukuvalwa kwe-annulus nokuthi ukuhlasela kokwakheka yi-filtrate yesimende kungaba yingozi ekukhiqizweni. Izithasiselo zokulahlekelwa koketshezi azigcini nje ngokunciphisa ukulahleka koketshezi lwesimende kodwa futhi zivimbela uketshezi oluhlungiwe ukuthi lungangcolisi ungqimba lukawoyela negesi, kuthuthukiswe ukusebenza kahle kokubuyisela.
