Izinto ezichaphazela ukuveliswa kwe-viscofity ye-HPMC

1. Ulawulo lwe-viscosity

I-viscosity yeHydroxypropyl Methylcelcelcelose ayinakukwazi ukuvelisa i-seluplose ephezulu kakhulu ngokuphuculwa kwaye ithathe indawo ye-nitrogen. Nangona kunjalo, ukuba isixhobo sokulinganisa ioksijini singafakwa kwiketile, ukuveliswa kwe-viscofity kunokulawulwa ngobugcisa.

2. Ukusetyenziswa kweearhente zonxibelelwano

Ukongeza, cinga ngesantya sokutshintsha kwe-nitrogen, kwaye kwangaxeshanye, ukuqina komoya kwale nkqubo kulungile, kwaye kulula kakhulu ukuvelisa iimveliso zokuthandabuza kakhulu. Ngokuqinisekileyo inqanaba le-polymerization yekotoni ehlaziyiweyo ibalulekile. Ukuba ayisebenzi, indlela yoMbutho weHydrophobic isetyenzisiwe, kwaye loluphi uhlobo lwearhente yoluntu ikhethiwe inempembelelo enkulu ekusebenzeni kwemveliso yokugqibela.

I-3. Umxholo weHydroxyPOpy

Ioksijini yentsalela kwi-kettle ye-kettile ibangela ukuba i-selsulose inciphise kwaye ubunzima bemolekyuli buncitshisiwe, kodwa ioksijini yentsalela inomda. Logama nje iimolekyuli ezaphukileyo zidityanisiwe, akunzima ukwenza i-viscofity ephezulu. Nangona kunjalo, ireyithi yokuqikeleka kwamanzi ikwanxulumene ngokusondeleyo nomxholo we-hydroxypropy, ezinye iifektri zifuna ukunciphisa iindleko kunye nexabiso kuphela, kwaye azifuni ukwandisa umgangatho weemveliso ezifanayo.

4. Ezinye izinto

Iqondo lokugcina amanzi lemveliso lunobudlelwane obukhulu kunye ne-hydroxypropy, kodwa kuyo yonke inkqubo yokugcina amanzi, ikwamisela i-alkali yokufumana amanzi, i-proplocane oxide, i-alkali kunye namanzi. Umyinge wekotoni ecocekileyo ibeka intsebenzo yemveliso.
