Izithasiselo Zokulawula Ukulahlekelwa Koketshezi Oluphezulu lwe-FC-634S
• I-FC-634S iyisengezo sokulahlekelwa uketshezi lwe-polymer lwesimende esisetshenziswa emthonjeni wamafutha futhi sakhiwe yi-copolymerization ene-AMPS/NN njenge-monomer eyinhloko enokumelana okuhle kokushisa nosawoti kanye nokuhlanganiswa namanye ama-monomer alwa nosawoti. Lo mkhiqizo wethule amaqembu angelula ukuwasebenzisa ukuze ukumelana nokushisa okuphezulu kuthuthukiswe kakhulu. 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-634S inokuguquguquka okuhle futhi ingasetshenziswa ezinhlelweni ezahlukene ze-simende slurry. Ihambisana kahle nezinye izithasiselo.
• I-FC-634S inobuthi obukhulu besilinganiso esiphansi sokucheba, okungathuthukisa ngempumelelo ukuzinza kokumiswa kohlelo lokucheba lwesimende, kugcine ukugeleza kobuthi, kuvimbele ukuchitheka kwenhlabathi ngesikhathi esifanayo, inokusebenza okuhle kokulawula imisele yegesi, ubuthi besilinganiso esiphansi sokucheba buphansi kune-FC-632S.
• I-FC-634S 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 amasha/usawoti.
I-Foring Chemical FLCA iyisengezo sokulahlekelwa uketshezi lwe-polymeric esingabizi kakhulu esenzelwe ukunciphisa ukulahlekelwa uketshezi olunomfutho ophezulu (HTHP) olusebenza kahle ezimweni nasezidingweni ezahlukene, njengamazinga okushisa aphezulu kanye nokugcwala kukasawoti ophezulu. I-FC-634S iyisengezo sokulawula ukulahlekelwa uketshezi olunokushisa okuphezulu futhi ifanele imakethe yaseRussia naseNyakatho 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.
