The mamasukidwe akayendedwe a HPMC ndi inversely proportional kutentha, ndiko, mamasukidwe akayendedwe kumawonjezeka monga kutentha amachepetsa.

HPMC kapena hydroxypropyl methylcellulose ndi chinthu chosunthika chomwe chimagwiritsidwa ntchito m'mafakitale osiyanasiyana kuphatikiza mankhwala, zodzoladzola ndi zakudya.Amagwiritsidwa ntchito kwambiri ngati thickener ndi emulsifier, ndipo makulidwe ake amasinthasintha malinga ndi kutentha komwe kumawonekera.M'nkhaniyi, tikambirana za ubale pakati pa mamasukidwe akayendedwe ndi kutentha mu HPMC.

Viscosity imatanthauzidwa ngati muyeso wa kukana kwamadzimadzi kutuluka.HPMC ndi theka-olimba mankhwala amene kukana muyeso zimadalira zinthu zosiyanasiyana, kuphatikizapo kutentha.Kuti timvetsetse mgwirizano pakati pa mamasukidwe akayendedwe ndi kutentha mu HPMC, choyamba tiyenera kudziwa momwe chinthucho chimapangidwira komanso momwe chimapangidwira.

HPMC imachokera ku cellulose, polima wopezeka mwachilengedwe muzomera.Kuti apange HPMC, cellulose iyenera kusinthidwa ndi propylene oxide ndi methyl chloride.Kusintha uku kumabweretsa kupanga magulu a hydroxypropyl ndi methyl ether mu unyolo wa cellulose.Chotsatira chake ndi chinthu chokhazikika chomwe chimatha kusungunuka m'madzi ndi organic solvents ndipo chimagwiritsidwa ntchito m'njira zosiyanasiyana, kuphatikizapo kupaka mapiritsi komanso ngati thickening wothandizira zakudya, pakati pa ena.

The mamasukidwe akayendedwe a HPMC zimadalira ndende ya chinthu ndi kutentha kumene izo poyera.Nthawi zambiri, mamasukidwe akayendedwe a HPMC amachepetsa ndi kuchuluka ndende.Izi zikutanthauza kuti kukwera kwakukulu kwa HPMC kumapangitsa kuti ma viscosity otsika komanso mosemphanitsa.

Komabe, mgwirizano wosiyana pakati pa kukhuthala ndi kutentha ndizovuta kwambiri.Monga tanenera kale, kukhuthala kwa HPMC kumawonjezeka ndi kuchepa kwa kutentha.Izi zikutanthauza kuti pamene HPMC ndi pansi kutentha otsika, mphamvu yake kuyenda amachepetsa ndipo amakhala viscous kwambiri.Momwemonso, pamene HPMC ikukumana ndi kutentha kwakukulu, mphamvu yake yothamanga imawonjezeka ndipo kukhuthala kwake kumachepa.

Pali zinthu zosiyanasiyana zomwe zimakhudza ubale wa kutentha ndi mamasukidwe akayendedwe mu HPMC.Mwachitsanzo, zosungunulira zina zomwe zimapezeka mumadzimadzi zimatha kukhudza kukhuthala, monganso pH yamadzimadzi.Kawirikawiri, pali mgwirizano wosiyana pakati pa kukhuthala ndi kutentha kwa HPMC chifukwa cha kutentha kwa hydrogen bonding ndi kuyanjana kwa maselo a unyolo wa cellulose mu HPMC.

Pamene HPMC ndi pansi kutentha otsika, unyolo mapadi kukhala okhwima, zomwe zimabweretsa kuwonjezeka kugwirizana haidrojeni.Zomangira za haidrojeni izi zimapangitsa kuti zinthu zisamayende bwino, motero zimakulitsa kukhuthala kwake.Mosiyana ndi zimenezi, pamene ma HPMC amatenthedwa kwambiri, maunyolo a cellulose anakhala osinthasintha, zomwe zinapangitsa kuti ma hydrogen bond achepetse.Izi zimachepetsa kukana kwa chinthucho kuti chisayende, zomwe zimapangitsa kuti ma viscosity achepetse.

Ndizofunikira kudziwa kuti ngakhale nthawi zambiri pamakhala mgwirizano wosiyana pakati pa kukhuthala ndi kutentha kwa HPMC, izi sizili choncho nthawi zonse pamitundu yonse ya HPMC.Ubale weniweni pakati pa mamasukidwe akayendedwe ndi kutentha ungasiyane kutengera momwe amapangira komanso kalasi yeniyeni ya HPMC yomwe imagwiritsidwa ntchito.

HPMC ndi multifunctional mankhwala chimagwiritsidwa ntchito m'mafakitale osiyanasiyana kwa thickening ndi emulsifying katundu.The mamasukidwe akayendedwe a HPMC zimadalira zinthu zingapo, kuphatikizapo ndende ya mankhwala ndi kutentha kumene poyera.Nthawi zambiri, mamasukidwe akayendedwe a HPMC ndi inversely proportional kutentha, kutanthauza kuti monga kutentha amachepetsa, mamasukidwe akayendedwe ukuwonjezeka.Izi zimachitika chifukwa cha kutentha kwa hydrogen bonding ndi kuyanjana kwa ma cell a cellulose mkati mwa HPMC.
