I-HydroxyEtheetheetheetheetheethy (hec) ihlala inyibilika kakhulu ngaphezulu koluhlu lobushushu olubanzi, nkqu nakwimimandla yobushushu e-Ionic apho i-selsulose ye-molsulose ye-ionic ye-molsulose (i-HPMCy) ye-METHYL POPIOT. Ukukhupha isizathu sokufana okuphezulu kwe-hec, iqondo lobushushu lokuxhomekeka kubume be-GLucopy kwi-GLucopy kwiisampulu ze-hec zavavanywa ngokusuka kwi-10 ukuya kwi-GHZ.
Kolu phononongo, iisampulu ze-hec zavavanywa kwinani le-molar le-HydroxyEtheetheethl Zonke iisampulu ze-hec zanyibilikiswa emanzini kuluhlu lwamaqondo obushushu ahlolwe kwaye abonakalise amanqaku e-tronsid. Ixabiso le-NH lesampulu ye-hec nge-14 nge-14 nge-20 ° C, kwaye inciphise kancinci ngeqondo lobushushu liphuma, kwaye liyele ukuya kwi-10 ngonyaka. Ixabiso le-pH yesampulu ye-hec ngokucacileyo ibaluleke kakhulu kunexabiso le-NH le-NH le-NH. I-5 I-Telupelose Even afana ne-MC kunye ne-HPMC kufuneka ichithwe emanzini, kwanakwinqanaba lobushushu obuphezulu.
Iimolekyuli zehek, nangona kunjalo, kukunyibilika kwamanzi ngaphezulu koluhlu lwamaqondo obushushu ngokubanzi. Iqondo lobushushu lokuxhomekeka kwe-NH leempulu ze-hec kunye ne-triglylicol (imodeli yemiqathango ye-HEC) ilele kwaye ziyafana. Oku kujongwa kubonisa ngamandla ukuba i-hydration / yokupheliswa kwemihlangi yeesampulu ze-hec ilawulwa ngamaqela abo. I-3 ngo-14 kwi-20 ° 7, ihla kancinci njengoko iqondo lobushushu liyaphuma, kwaye liyele ukuya kwi-10 ngo-70 ° C. Ixabiso le-NH lesampulu ye-hec ngokucacileyo inkulu kakhulu kunexabiso le-NH le-NH le-NH. I-5 I-Telupelose Even afana ne-MC kunye ne-HPMC kufuneka ichithwe emanzini, kwanakwinqanaba lobushushu obuphezulu. Iimolekyuli zehek, nangona kunjalo, kukunyibilika kwamanzi ngaphezulu koluhlu lwamaqondo obushushu ngokubanzi. Iqondo lobushushu lokuxhomekeka kwe-NH leempulu ze-hec kunye ne-triglylicol (imodeli yemiqathango ye-HEC) ilele kwaye ziyafana.
Oku kujongwa kubonisa ngamandla ukuba i-hydration / yokupheliswa kwemihlangi yeesampulu ze-hec ilawulwa ngamaqela abo.

Oku kujongwa kubonisa ngamandla ukuba i-hydration / yokupheliswa kwemihlangi yeesampulu ze-hec ilawulwa ngamaqela abo. Iimolekyuli zehek zinyibilika amanzi kuluhlu lobushushu ngokubanzi.
