FC-620S Fluid ilahleko Control izongezo
• I-FC-620S sisidibaniso selahleko yepolymeryesamente esetyenziswa kwiioli kakuhlekwaye yenziwe yi-copolymerization ngeAMPSnjengengundoqoi-monomer enobushushu obuhle kunye nokumelana netyuwakwaye ngokudibanisa nezinye ezichasene netyuwaimonomers.Iiimolekyuli ziqulathe inani elikhulu lamaqela adsorptive kakhulu ezifana - CONH2, - SO3H, - COOH, ezidlalayosindima ebalulekileyo ekuxhathiseni ityuwa, ukumelana nobushushu, ukufunxa amanzi asimahla, ukunciphisa ukulahleka kwamanzi, njl.
• I-FC-620S ilungele ubushushu obubanzingeukumelana nobushushu obuphezulu ukuya kuthi ga kwi-150 ℃.Emva kokusetyenziswa, iubumanzi benkqubo yodaka lwesamenteilungile, izinzile ngolwelo olungenasimahla kwaye ngaphandle kokucotha iseti kunye namandla akhula ngokukhawuleza.
•FC-620Sisilungele iintlobo ngeentlobo zeenkqubo zodaka lwesamente yamanzi olwandle.Inokuhambelana kakuhle nezinye izongezo.
•FI-C-620S ine-dispersibility eyomeleleyo, ngokukodwa ifanelekile kwiinkqubo ze-samente yamanzi ahlambulukileyo kunye nomxholo ophezulu oqinileyo okanye izinto eziphezulu eziphezulu.
Amasimi e-oyile anobushushu obuphezulu ajongana neseti eyodwa yemiceli mngeni xa kufikwa ekufakweni kwesamente kakuhle.Enye yale mingeni ngumba wokulahlekelwa kwamanzi, okunokuthi kwenzeke xa i-filtrate yodaka lokugaya ihlasela ukubunjwa kwaye ibangele ukucutha umthamo wamanzi.Ukusombulula le ngxaki, siye saqulunqa isinciphisi esikhethekileyo sokulahleka kolwelo olulungiselelwe ngokukodwa ukusetyenziswa kwiindawo zeoli ezinobushushu obuphezulu.

Ngaphezulu kweminyaka engama-20, ii-arhente zokulawula ilahleko yolwelo ziye zongezwa kwi-oyile-well well-cement slurries kwaye ngoku iyaqatshelwa kwishishini ukuba umgangatho wemisebenzi yesamente uphucuke kakhulu.Ewe, ngokubanzi ivunywa ngokucacileyo ukuba ukunqongophala kolawulo lwelahleko yolwelo kunokuba noxanduva lokungaphumeleli kwesamente okuphambili, ngenxa yokwanda koxinzelelo olugqithisileyo okanye i-annulus bridging kunye nokuba uhlaselo lobume ngohluzo lwesamente lunokuba lucime kwimveliso.Isongezo sokulahleka kolwelo asikwazi kuphela ukulawula ngokufanelekileyo ilahleko yolwelo lwe-samente eludaka, kodwa kwakhona sithintele umaleko we-oyile kunye negesi ekungcolisweni lulwelo oluhluziweyo kwaye ngaloo ndlela ukwandisa ukusebenza kakuhle kokubuyisela.
