I-viscosity ye-HPMC ilingana ngokuphambene nezinga lokushisa, okungukuthi, i-viscosity iyanda njengoba izinga lokushisa lincipha.

I-HPMC noma i-hydroxypropyl methylcellulose iyinto eguquguqukayo esetshenziswa ezimbonini ezahlukahlukene ezihlanganisa ezemithi, izimonyo nokudla.Isetshenziswa kabanzi njenge-thickener ne-emulsifier, futhi i-viscosity yayo iyashintsha kuye ngezinga lokushisa elivezwa kulo.Kulesi sihloko, sizogxila ebudlelwaneni phakathi kwe-viscosity nezinga lokushisa ku-HPMC.

I-viscosity ichazwa njengesilinganiso sokumelana koketshezi nokugeleza.I-HPMC into eqinile kancane isilinganiso sayo sokumelana sincike ezintweni ezihlukahlukene, okuhlanganisa izinga lokushisa.Ukuze siqonde ubudlelwano phakathi kwe-viscosity nezinga lokushisa ku-HPMC, okokuqala sidinga ukwazi ukuthi into yakhekeka kanjani nokuthi yenziwa ngani.

I-HPMC isuselwa ku-cellulose, i-polymer eyenzeka ngokwemvelo ezitshalweni.Ukukhiqiza i-HPMC, i-cellulose idinga ukushintshwa amakhemikhali nge-propylene oxide ne-methyl chloride.Lokhu kuguqulwa kuholela ekwakhekeni kwamaqembu e-hydroxypropyl kanye ne-methyl ether ochungechungeni lwe-cellulose.Umphumela uba into eqinile engancibilikisiwe emanzini nasezincibilikiseni eziphilayo futhi isetshenziswa ezinhlobonhlobo zezicelo, okuhlanganisa njengokumboza amaphilisi nanjenge-ejenti yokuqina kokudla, phakathi kokunye.

I-viscosity ye-HPMC incike ekugxilweni kwento kanye nezinga lokushisa lapho ivezwa khona.Ngokuvamile, i-viscosity ye-HPMC iyancipha ngokugxila okukhulayo.Lokhu kusho ukuthi ukugxila okuphezulu kwe-HPMC kubangela ama-viscosities aphansi futhi ngokuphambene nalokho.

Nokho, ubudlelwano obuphambene phakathi kwe-viscosity nezinga lokushisa buyinkimbinkimbi kakhulu.Njengoba kushiwo ngaphambili, i-viscosity ye-HPMC iyanda ngokuncipha kwezinga lokushisa.Lokhu kusho ukuthi uma i-HPMC ingaphansi kwamazinga okushisa aphansi, amandla ayo okugeleza ayancipha futhi iba ne-viscous.Ngokufanayo, lapho i-HPMC ingaphansi kwamazinga okushisa aphezulu, amandla ayo okugeleza ayanda futhi i-viscosity yayo iyancipha.

Kunezici ezihlukahlukene ezithinta ubudlelwano phakathi kwezinga lokushisa kanye ne-viscosity ku-HPMC.Isibonelo, ezinye izinyibilikisi ezikhona oketshezini zingathinta i-viscosity, kanjalo ne-pH yoketshezi.Nokho, ngokuvamile, kunobudlelwano obuphambene phakathi kwe-viscosity nezinga lokushisa ku-HPMC ngenxa yomphumela wokushisa ekubopheni i-hydrogen nokusebenzisana kwamangqamuzana amaketanga e-cellulose ku-HPMC.

Uma i-HPMC ingaphansi kwamazinga okushisa aphansi, amaketanga e-cellulose aba aqinile, okuholela ekwandeni kwe-hydrogen bonding.Lawa mabhondi e-hydrogen abangela ukuthi ukuphikiswa kwento kugeleze, ngaleyo ndlela kwandise i-viscosity yayo.Ngokuphambene, lapho ama-HPMC engaphansi kwamazinga okushisa aphezulu, amaketanga e-cellulose ashintshashintsha, okuholele ekunciphiseni kwamabhondi e-hydrogen.Lokhu kunciphisa ukumelana kwento ukugeleza, okuholela ekubonakaleni okuphansi kwe-viscosity.

Kuyaphawuleka ukuthi nakuba ngokuvamile kukhona ubudlelwano obuphambene phakathi kwe-viscosity nezinga lokushisa le-HPMC, lokhu akuhlali kunjalo kuzo zonke izinhlobo ze-HPMC.Ubudlelwano obuqondile phakathi kwe-viscosity nezinga lokushisa bungahluka kuye ngenqubo yokukhiqiza kanye nebanga elithile le-HPMC elisetshenzisiwe.

I-HPMC iyisithako esisebenza ngezinto eziningi esisetshenziswa kabanzi ezimbonini ezehlukene ngenxa yokuqina kwayo kanye nezakhiwo ze-emulsifying.I-viscosity ye-HPMC incike ezintweni ezimbalwa, okuhlanganisa ukugxila kwento kanye nezinga lokushisa lapho ivezwa khona.Ngokuvamile, i-viscosity ye-HPMC ihambisana ngokuphambene nezinga lokushisa, okusho ukuthi njengoba izinga lokushisa liyancipha, i-viscosity iyanda.Lokhu kungenxa yomphumela wezinga lokushisa ekubopheni i-hydrogen nokusebenzisana kwamangqamuzana amaketango e-cellulose ngaphakathi kwe-HPMC.
