Izithasiselo zokulawula ukulahlekelwa uketshezi ze-FC-FR220S
I-FC-FR220S yokulawula ukulahlekelwa uketshezi, i-sulphonate copolymer (uketshezi lokubhoboza), isebenzisa umqondo womklamo wesakhiwo sama-molecule ukuthuthukisa ukuqina kwe-molecule ye-copolymer. Iyunithi yokuphindaphinda ye-monomer eyethulwe inomthamo omkhulu wesikhala, engakhuphula ngempumelelo isithiyo se-steric futhi ithuthukise umphumela womkhiqizo ekulawuleni ukulahlekelwa uketshezi lwe-HTHP; Ngesikhathi esifanayo, ikhono layo lokumelana nokushisa kanye ne-calcium kasawoti lithuthukiswa ngokwengeziwe ngokusebenzisa ngcono amazinga okushisa kanye nama-monomer abekezelela usawoti. Lo mkhiqizo unqoba ukushiyeka kokulawulwa kokulahlekelwa uketshezi lwe-polymer okuvamile, njengokumelana nokucheba okubi, ukumelana ne-calcium kasawoti embi, kanye nomphumela ongagculisi wokulawula ukulahlekelwa uketshezi lwe-HTHP. Kuyindlela entsha yokulawula ukulahlekelwa uketshezi lwe-polymer.

1. I-FC-FR220S inokumelana okuqinile nosawoti. Ngokusebenzisa izivivinyo zangaphakathi, lungisa okuqukethwe usawoti ohlelweni loketshezi lokubhoboza olusetshenziswa ukuhlola ukuphikiswa kosawoti komkhiqizo we-FC-FR220S ngemva kokuguga ku-200 ℃ odakeni oluyisisekelo olunokuqukethwe okuhlukile kosawoti. Imiphumela yokuhlolwa iboniswe kuMfanekiso 1:
Isaziso: Ukwakheka kwe-slurry eyisisekelo yokuhlola: 6% w/v inhlabathi ye-sodium+4% w/v inhlabathi yokuhlola+1.5% v/v isixazululo se-alkali (ukuhlushwa okungu-40%);
Ukulahleka koketshezi lwe-HTHP kufanele kuhlolwe ku-150℃ ku-3.5MPa.
Kungabonakala emiphumeleni yokuhlola kuMfanekiso 1 ukuthi i-FC-FR220S inamandla amahle kakhulu ekulawuleni ukulahleka koketshezi lwe-HTHP ngaphansi kokuqukethwe okuhlukene kukasawoti, futhi inamandla aqinile kanye nokumelana nosawoti okuhle kakhulu.
2. I-FC-FR220S inokuqina okuhle kakhulu kokushisa. Ukuhlolwa kwangaphakathi kwenziwa ukuze kuhlolwe umkhawulo wokumelana nokushisa komkhiqizo we-FC-FR220S ku-slurry ye-brine engu-30% ngokukhulisa kancane kancane izinga lokushisa lokuguga kwe-FC-FR220S. Imiphumela yokuhlolwa iboniswe kuMfanekiso 2:
Isaziso: Ukulahleka koketshezi lwe-HTHP kuhlolwa ku-150 ℃ kanye no-3.5MPa.
Kungabonakala emiphumeleni yokuhlola kuMfanekiso 2 ukuthi i-FC-FR220S isenendima enhle ekulawuleni ukulahleka koketshezi lwe-HTHP ku-220℃ ngokukhuphuka kwezinga lokushisa, futhi inokumelana okuhle kakhulu kwezinga lokushisa futhi ingasetshenziswa emthonjeni ojulile kanye nokubhoboza imigodi ejulile kakhulu. Idatha yokuhlola ikhombisa nokuthi i-FC-FR220S inengozi yokumuncwa kwezinga lokushisa eliphezulu ku-240℃, ngakho-ke akukhuthazwa ukuyisebenzisa kuleli zinga lokushisa noma ngaphezulu.
3. I-FC-FR220S ihambisana kahle. Ukusebenza kwe-FC-FR220S ngemva kokuguga ku-200℃ emanzini olwandle, i-compound brine kanye nezinhlelo zokusebenzisa uketshezi lokubhoboza i-brine egcwele kuphenywa ngokuhlolwa kwelebhu. Imiphumela yokuhlolwa iboniswe kuThebula 2:
Ithebula 2 Imiphumela Yokuhlola Ukusebenza kwe-FC-FR220S Ezinhlelweni Ezihlukene Zokubhoboza Uketshezi
| Into | I-AV mPa.s | I-FL API ml | I-FL HTHP ml | Isaziso |
| Uketshezi lokubhoboza amanzi olwandle | 59 | 4.0 | 12.4 | |
| Uketshezi lokubhoboza usawoti oluhlanganisiwe | 38 | 4.8 | 24 | |
| Uketshezi lokubhoboza olugcwele amanzi acwebezelayo | 28 | 3.8 | 22 |
Kungabonakala emiphumeleni yokuhlola kuThebula 2 ukuthi i-FC-FR220S ihambisana kahle futhi iyindlela enhle kakhulu yokulawula ukulahleka koketshezi kokulawula ukulahleka koketshezi lwe-HTHP kwezinhlelo zoketshezi zokubhoboza njengamanzi olwandle, i-compound brine kanye ne-saturated brine, njll.
