Izongezo zoLawulo lokulahleka kolwelo lwe-FC-620S
• I-FC-620S sisixhobo sokongeza ukulahleka kolwelo lwepolymeryesamente esetyenziswa kwiumthombo weoyilekwaye yenziwe yi-copolymerization kunyeii-AMPSnjengeyona nto iphambilii-monomer enobushushu obuhle kunye nokumelana netyuwakwaye xa idibene nezinye izinto ezichasene netyuwai-monomers. Iiimolekyuli ziqulathe inani elikhulu lamaqela afunxa kakhulu afana ne-CONH2, -SO3H, -COOH, adlalasindima ebalulekileyo ekumelaneni netyuwa, ukumelana nobushushu, ukufunxwa kwamanzi asimahla, ukunciphisa ukulahleka kwamanzi, njl..
• I-FC-620S ifanelekile kubushushu obubanzikunyeukumelana nobushushu obuphezulu ukuya kuthi ga kwi-150℃Emva kokusetyenziswa,ukutyibilika kwenkqubo yodaka lwesamenteilungile, izinzile xa ingenamanzi amaninzi kwaye ayinakucotha kwaye amandla ayo akhula ngokukhawuleza.
•FC-620Sisifanelekile kwiinkqubo ezahlukeneyo zesamente yamanzi olwandle. Ihambelana kakuhle nezinye izongezo.
•FI-C-620S inokwahlulwahlulwa okunamandla, ngakumbi ifanelekile kwiinkqubo zesamente yamanzi acocekileyo ezinomxholo ophezulu oqinileyo okanye izinto ezikumgangatho ophezulu.
Iintsimi yeoyile ezinobushushu obuphezulu zijongene nemingeni eyahlukileyo xa kufikwa ekufakweni kwesamente emthonjeni. Enye yezi mingeni yingxaki yokulahleka kolwelo, okunokwenzeka xa i-filtrate yodaka lokugrumba ingena ekwakhekeni kwayo kwaye ibangele ukwehla komthamo wolwelo. Ukusombulula le ngxaki, siye saphuhlisa isixhobo esikhethekileyo sokunciphisa ukulahleka kolwelo esenzelwe ngokukodwa ukusetyenziswa kwiintsimi yeoyile ezinobushushu obuphezulu.

Kangangeminyaka engaphezu kwama-20, izinto zokulawula ukulahleka kolwelo zongezwe kwi-oil-source cement slurry kwaye ngoku kuyaziwa kwishishini ukuba umgangatho wemisebenzi yokufaka i-cement uphucuke kakhulu. Enyanisweni, ngokubanzi kuyavunywa ngokucacileyo ukuba ukungabikho kolawulo lokulahleka kolwelo kunokubangela ukusilela kokuqala kwe-cement, ngenxa yokwanda koxinano okanye i-annulus bridging kwaye ukuhlaselwa kokwakheka yi-cement filtrate kunokuba yingozi kwimveliso. I-fluid loss additive ayinakulawula kuphela ukulahleka kolwelo lwe-cement slurry, kodwa ikwathintela umaleko we-oyile negesi ekubeni ungcoliswe lulwelo oluhluziweyo kwaye ngaloo ndlela yonyusa ukusebenza kakuhle kokubuyisela.
