Izongezo zoLawulo lokulahleka kolwelo lwe-FC-650S
• I-FC-650S sisithako sokulahleka kolwelo lwepolymer kwisamente esetyenziswa kwi-oyile well kwaye senziwe yi-copolymerization ene-AMPS/NN/HA njenge-monomer ephambili enokumelana kakuhle nobushushu kunye netyuwa kwaye idityaniswe nezinye ii-monomers ezichasene netyuwa. Iimolekyuli ziqulathe inani elikhulu lamaqela anomdla kakhulu afana ne-CONH2, - SO3H, - COOH, edlala indima ebalulekileyo ekumelaneni netyuwa, ukumelana nobushushu, ukufunxwa kwamanzi asimahla, ukunciphisa ukulahleka kwamanzi, njl.
• I-FC-650S inokuguquguquka okuhle kwaye ingasetyenziswa kwiinkqubo ezahlukeneyo zesamente. Ihambelana kakuhle nezinye izongezo.
• I-FC-650S ifanelekile kubushushu obubanzi obunokumelana nobushushu obuphezulu ukuya kuthi ga kwi-230℃. Isebenza ngcono ekuzinzeni kokuxhonywa kwindawo enobushushu obuphezulu ngenxa yokungenisa i-humic acid.
• I-FC-650S ingasetyenziswa yodwa. Isiphumo siba ngcono xa isetyenziswa kunye ne-FC-631S/ FC-632S.
• Ifanelekile ekulungiseleleni ulwelo lwamanzi acocekileyo/amanzi anetyuwa.
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.

| I-FC-650S | I-FLAC HT | I-AMPS+NN+I-Humic acid | <230degC |
| Into | Ii-ndex |
| Inkangeleko | Umgubo omhlophe ukuya kotyheli okhanyayo |
| Into | Isalathiso sobugcisa | Imeko yovavanyo |
| Ukulahleka kwamanzi, i-mL | ≤50 | 80℃, 6.9MPa |
| Ixesha le-multiviscosity, umzuzu | ≥60 | 80℃, 45MPa/45min |
| ukufana kokuqala, i-Bc | ≤30 | |
| Amandla oxinzelelo, i-MPa | ≥14 | 80℃, uxinzelelo oluqhelekileyo, iiyure ezingama-24 |
| Amanzi asimahla, mL | ≤1.0 | 80℃, uxinzelelo oluqhelekileyo |
| Inxalenye yesamente esiludaka: Isamente ye-100% ye-grade G (emelana ne-sulfate ephezulu)+44.0% amanzi acocekileyo+0.9% FC-650S+0.5% iarhente yokucoca i-foam. | ||
Iiarhente zokulawula ilahleko yolwelo ziye zaziswa kwi-slurry zesamente ye-oyile kangangeminyaka engaphezu kwama-20, kwaye eli shishini liye laqonda ukuba oku kuye kwawuphucula kakhulu umgangatho weeprojekthi zesamente. Enyanisweni, kuyamkelwa kakuhle ukuba ukungabikho kolawulo lokulahleka kolwelo kunokuba yimbangela yokusilela kwesamente ngenxa yokwanda koxinano okanye i-annulus bridging kwaye ukuhlaselwa kokwakheka yi-filtrate yesamente kunokuba yingozi kwimveliso. Izongezo zokulahleka kolwelo azinciphisi nje kuphela ilahleko yolwelo lwesamente kodwa zikwagcina ulwelo oluhluziweyo ukuba lungangcolisi umaleko weoyile negesi, nto leyo ephucula ukusebenza kakuhle kokubuyisela.
