Izithasiselo zokulawula ukulahlekelwa uketshezi ze-FC-620S
• I-FC-620S iyisengezo sokulahlekelwa uketshezi lwe-polymeryesamente esetshenziswa kuumthombo wamafuthafuthi yakhiwe yi-copolymerization ngeAma-AMPnjengento eyinhlokoi-monomer enokushisa okuhle kanye nokumelana nosawotifuthi kuhlanganiswe nezinye izinto ezilwa nosawotii-monomers. Iama-molecule aqukethe inani elikhulu lamaqembu ancelisayo kakhulu njenge-CONH2, -SO3H, -COOH, adlalasindima ebalulekile ekumelaneni nosawoti, ukumelana nokushisa, ukumuncwa kwamanzi mahhala, ukunciphisa ukulahleka kwamanzi, njll..
• I-FC-620S ifaneleka ekushiseni okubanzingeukumelana nokushisa okuphezulu kuze kufike ku-150℃Ngemva kokusebenzisa,ukugeleza kohlelo lwe-slurry lukasimendeilungile, izinzile uma inoketshezi oluncane futhi ayinawo amandla okubuyela emuva futhi ikhula ngokushesha.
•FC-620Sisifanele izinhlelo ezahlukene ze-slurry cement cement zamanzi olwandle. Ihambisana kahle nezinye izithako.
•FI-C-620S iyakwazi ukuhlakazeka kakhulu, ikakhulukazi ifanele izinhlelo ze-slurry zesamente yamanzi ahlanzekile ezinokuqukethwe okuphezulu okuqinile noma izinto ezisezingeni eliphezulu.
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.

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.
