Izongezo zoLawulo lokulahleka kolwelo ze-FC-FR220S
I-FC-FR220S yokulawula ukulahleka kolwelo i-sulphonate copolymer (ulwelo lokugrumba) isebenzisa ingcamango yoyilo lwesakhiwo se-molecular ukuphucula ukuqina kwemolekyuli ye-copolymer. Iyunithi ephindayo ye-monomer engenisiweyo inomthamo omkhulu wendawo, enokunyusa ngempumelelo isithintelo se-steric kwaye iphucule isiphumo semveliso ekulawuleni ukulahleka kolwelo lwe-HTHP; Kwangaxeshanye, amandla ayo okumelana nobushushu kunye ne-calcium yetyuwa aphuculwa ngakumbi ngokuphucula ubushushu kunye nee-monomers ezinyamezela ityuwa. Le mveliso yoyisa iziphene zolawulo lokulahleka kolwelo lwe-polymer oluqhelekileyo, olufana nokungaxhathisi kakuhle kwe-shear, ukunganyamezeli kakuhle kwe-calcium yetyuwa, kunye nesiphumo esinganelisiyo sokulawula ukulahleka kolwelo lwe-HTHP. Lulawulo olutsha lokulahleka kolwelo lwe-polymer.

1. I-FC-FR220S inokumelana okukhulu netyuwa. Ngokusebenzisa uvavanyo lwangaphakathi, lungisa umxholo wetyuwa kwinkqubo yolwelo lokubhola esetyenziselwa uvavanyo ukuphanda ukumelana netyuwa yemveliso ye-FC-FR220S emva kokuguga kwi-200 ℃ eludakeni olusisiseko olunomxholo wetyuwa owahlukileyo. Iziphumo zovavanyo ziboniswe kuMfanekiso 1:
Isaziso: Ukwakheka kodaka olusisiseko lokuvavanya: 6% w/v umhlaba wesodium+4% w/v umhlaba wokuvavanya+1.5% v/v isisombululo se-alkali (uxinzelelo lwe-40%);
Ukulahleka kolwelo lwe-HTHP kuya kuvavanywa kwi-150℃ kwi-3.5MPa.
Kuyabonakala kwiziphumo zovavanyo ezikwiMfanekiso 1 ukuba i-FC-FR220S inomsebenzi ogqwesileyo ekulawuleni ukulahleka kolwelo lwe-HTHP phantsi komxholo wetyuwa owahlukileyo, kwaye inomsebenzi ozinzileyo kunye nokumelana netyuwa okugqwesileyo.
2. I-FC-FR220S inozinzo oluhle kakhulu kubushushu. Uvavanyo lwangaphakathi lwenziwa ukuphanda umda wokumelana nobushushu bemveliso ye-FC-FR220S kwi-30% ye-brine slurry ngokunyusa kancinci ubushushu bokwaluphala be-FC-FR220S. Iziphumo zovavanyo ziboniswe kuMfanekiso 2:
Isaziso: Ukulahleka kolwelo lwe-HTHP kuvavanywa kwi-150 ℃ kunye ne-3.5MPa.
Kuyabonakala kwiziphumo zovavanyo ezikwiMfanekiso 2 ukuba i-FC-FR220S isenendima entle ekulawuleni ukulahleka kolwelo lwe-HTHP kwi-220℃ ngokunyuka kobushushu, kwaye inokumelana okuhle kobushushu kwaye ingasetyenziselwa ukugrumba umngxuma onzulu kakhulu kunye nokugrumba umngxuma onzulu kakhulu. Idatha yovavanyo ikwabonisa ukuba i-FC-FR220S inomngcipheko wokutsalwa kobushushu obuphezulu kwi-240℃, ngoko ke akukhuthazwa ukuyisebenzisa kweli qondo lobushushu okanye ngaphezulu.
3. I-FC-FR220S ihambelana kakuhle. Ukusebenza kwe-FC-FR220S emva kokuguga kwi-200℃ emanzini olwandle, kwi-compound brine kunye neenkqubo zolwelo lokubhola i-brine eyosiweyo kuphandwa ngovavanyo lwelebhu. Iziphumo zovavanyo ziboniswe kwiTheyibhile 2:
Itheyibhile 2 Iziphumo zoVavanyo lokuSebenza kwe-FC-FR220S kwiiNkqubo ezahlukeneyo zoLwakhiwo lokuDrila
| Into | I-AV mPa.s | I-FL API ml | I-FL HTHP ml | Ingxelo |
| Ulwelo lokugrumba amanzi olwandle | 59 | 4.0 | 12.4 | |
| Ulwelo lokubhola olunetyuwa edityanisiweyo | 38 | 4.8 | 24 | |
| Ulwelo lokubhola olunetyuwa eyomileyo | 28 | 3.8 | 22 |
Kuyabonakala kwiziphumo zovavanyo kwiTheyibhile 2 ukuba i-FC-FR220S ihambelana kakuhle kwaye iyindlela ebalaseleyo yokulawula ukulahleka kolwelo lwe-HTHP kwiinkqubo zolwelo lokubhola ezifana namanzi olwandle, i-compound brine kunye ne-saturated brine, njl.njl.
