HPMC viscosity

I-HPMC (i-hydroxypropyl methylcellulose) luhlobo lwe-viscosity modifier, i-thickener, kunye ne-stabilizer esetyenziswa kumashishini ahlukeneyo. Ngumgubo omhlophe, ongenavumba, ongenancasa ophuma kwiselulosi kwaye usetyenziswa kwizinto ezahlukeneyo, kubandakanywa ukutya, amayeza, izinto zokuthambisa, kunye neemveliso zoshishino. I-HPMC yi-non-ionic, i-polymer enyibilikayo emanzini esetyenziselwa ukwandisa i-viscosity yezisombululo ezinamanzi. Yi-agent esebenzayo kakhulu yokuqina kwaye isetyenziselwa ukuphucula ukuthungwa kunye nokuzinza kweemveliso.

I-HPMC yimveliso eguquguqukayo enokusetyenziswa kwizicelo ezahlukeneyo. Kwishishini lokutya, isetyenziselwa ukwenza iisosi ezityebileyo, iigravies kunye neesuphu. Ikwasetyenziselwa ukuzinzisa i-emulsions kunye nokumiswa, kunye nokuphucula ukuthungwa kunye nobomi beshelufu yeemveliso. Kumashishini amayeza, isetyenziselwa ukuphucula ukunyibilika kweziyobisi, ukwandisa i-viscosity yokumiswa, kunye nokuzinzisa i-emulsions. Kwishishini lezithambiso, isetyenziselwa ukujiya iikhrimu, izinto zokuthambisa, neegel, kunye nokuphucula ukuthungwa nokuzinza kweemveliso.

I-viscosity yezisombululo ze-HPMC ithathwa bubunzima bemolekyuli yepolymer, ukuxinwa kwesisombululo, kunye nobushushu. I-viscosity yezisombululo ze-HPMC iyanda ngokunyuka kobunzima bemolekyuli kunye noxinzelelo, kwaye iyancipha ngokunyuka kobushushu. I-viscosity yezisombululo ze-HPMC zinokuhlengahlengiswa ngokongeza ezinye iipholima okanye ii-surfactants.

I-HPMC yimveliso ekhuselekileyo nesebenzayo esetyenziswa ngokubanzi kumashishini ahlukeneyo. Ayinatyhefu, ayicaphukisi, kwaye ayinayo i-allergenic, kwaye ivunyiwe ukuba isetyenziswe ekutyeni, kumayeza, nakwizinto zokuthambisa. Iyakwazi ukubola kwaye ihambelana nokusingqongileyo. I-HPMC yi-arhente ebalaseleyo yokuqina kwaye isetyenziselwa ukuphucula ukuthungwa kunye nokuzinza kweemveliso. Ikwasetyenziselwa ukunyusa i-viscosity yezisombululo ezinamanzi, ukuzinzisa i-emulsions, kunye nokuphucula ukunyibilika kweziyobisi.
