Polyanionic Cellulose

I-Polyanionic cellulose (PAC) yi-derivative ye-cellulose e-soluble yamanzi efumana ukusetyenziswa ngokubanzi kwizicelo ezahlukeneyo zoshishino, ngokukodwa kwi-oyile kunye ne-gas drilling industry. Nantsi isishwankathelo se-polyanionic cellulose:

1. Ukubunjwa: I-Polyanionic cellulose ivela kwi-cellulose, i-polymer yendalo efumaneka kwizityalo, ngokuguqulwa kweekhemikhali. Amaqela e-Carboxymethyl aziswa kwi-cellulose backbone, enika iipropati ze-anionic (ezihlawuliswa kakubi).

2. Ukusebenza:

• I-Viscosifier: I-PAC isetyenziswa ngokuyintloko njenge-viscosifier kumanzi okugaya asekelwe emanzini. Inika i-viscosity kwi-fluid, iphucula amandla ayo okumisa kunye nokuthutha i-cuttings egrunjiweyo phezulu.
• Ulawulo lwelahleko yolwelo: I-PAC yenza ikeyiki ecekethekileyo, engangenekiyo yokucoca kudonga lomngxuma, inciphisa ukulahleka kolwelo ekubunjweni kwayo kunye nokugcina uzinzo lwequla.
• I-Rheology Modifier: I-PAC inefuthe kwindlela yokuziphatha kunye neempawu zerheological zolwelo lokomba, ukuqinisa ukunqunyanyiswa kwezinto eziqinileyo kunye nokunciphisa ukuzinza.

3. Usetyenziso:

• I-Oli kunye neGesi yoKwemba: I-PAC yongeziweyo engundoqo kumanzi okugaya asekelwe emanzini asetyenziselwa ukuhlola i-oyile kunye negesi kunye nemveliso. Inceda ukulawula i-viscosity, ilahleko yolwelo, kunye ne-rheology, iqinisekisa ukusebenza ngokufanelekileyo kokomba kunye nokuzinza kwe-wellbore.
• Ulwakhiwo: I-PAC isetyenziswa njenge-ejenti yokuqinisa kunye nokugcina amanzi kwimixube yesamente efana ne-grouts, i-slurries, kunye nodaka olusetyenziswa kwizicelo zokwakha.
• I-Pharmaceuticals: Ekuqulunqweni kwamachiza, i-PAC isebenza njenge-binder, i-disintegrant, kunye ne-ejenti yokukhululwa elawulwayo kwi-tablet kunye ne-capsule formulations.

4. Iinkcazelo ngeempawu:

• Ukunyibilika kwamanzi: I-PAC inyibilika ngokulula emanzini, ivumela ukudityaniswa lula kwiinkqubo ezinamanzi ngaphandle kwemfuneko yezinyibilikisi ezongezelelweyo okanye izisasazi.
• Ukuzinza okuphezulu: I-PAC ibonisa ukuzinza okuphezulu kwe-thermal kunye neekhemikhali, igcina iimpawu zayo zokusebenza kwiindidi ezininzi zokushisa kunye neemeko ze-pH.
• Ukunyamezelwa kweTyuwa: I-PAC ibonisa ukuhambelana okuhle kunye namazinga aphezulu eetyuwa kunye neebrines ezihlala zidibana kwindawo yeoli.
• Ukonakala kwezinto eziphilayo: I-PAC ithathwe kwimithombo ehlaziyekayo esekwe kwizityalo kwaye iyakwazi ukubola, nto leyo eyenza ukuba ihambelane nokusingqongileyo.

5. Umgangatho kunye neeNgcaciso:

• Iimveliso zePAC zifumaneka kumabanga ahlukeneyo kunye neenkcukacha ezilungiselelwe izicelo ezithile kunye neemfuno zokusebenza.
• Amanyathelo olawulo lomgangatho aqinisekisa ukuhambelana kunye nokuthotyelwa kwemigangatho yoshishino, kubandakanywa ne-API (i-American Petroleum Institute) inkcazo ye-drilling fluid additives.

Isishwankathelo, i-polyanionic cellulose yinto eyongeziweyo kunye neyongezelelweyo esebenzayo kunye ne-viscosifying, ulawulo lokulahlekelwa kwamanzi, kunye neempawu ze-rheological, okwenza kube yinto ebalulekileyo kwizicelo ezahlukeneyo zemizi-mveliso, ngakumbi kwishishini le-oyile kunye negesi yokomba. Ukuthembeka kwayo, ukusebenza kwayo, kunye nokuhambelana nokusingqongileyo kunegalelo ekusetyenzisweni kwayo ngokubanzi kwiindawo zokomba ezinomngeni.
