Hydroxypropylmethylcellulose (HPMC) ndi etha ya cellulose yochokera kuzinthu zachilengedwe monga zamkati zamatabwa ndi ma linter a thonje.Chifukwa cha katundu wake wapadera, kuphatikizapo kusungunuka kwa madzi, kukulitsa mphamvu, kupanga mafilimu, ndi zina zotero, zimagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana.Chimodzi mwazinthu zofunika kuziganizira mukamagwiritsa ntchito HPMC ndi kukhuthala kwake, zomwe zingakhudze kwambiri magwiridwe antchito osiyanasiyana.M'nkhaniyi, tikambirana chifukwa chake cellulose HPMC yokhala ndi ma viscosity osiyanasiyana iyenera kusankhidwa kumalo osiyanasiyana ogwiritsira ntchito, komanso momwe kukhuthala koyenera kumathandizira kukhathamiritsa magwiridwe antchito a HPMC.
Viscosity ndi muyeso wa kukana kwamadzimadzi kuti asasunthike ndipo ndikofunikira kuganizira popanga zinthu zomwe zimafunikira mawonekedwe apadera otaya.Viscosity imakhudza magwiridwe antchito a HPMC chifukwa imatsimikizira kuthekera kwake kopanga ma gels, kumakhudza pH ya yankho, makulidwe a zokutira, ndi zinthu zina zakuthupi.HPMC imapezeka m'makalasi osiyanasiyana a viscosity, mitundu yodziwika kwambiri kukhala kukhuthala kotsika (LV), kukhuthala kwapakatikati (MV) ndi kukhuthala kwakukulu (HV).Iliyonse mwa mitundu iyi ili ndi cholinga chake ndipo ndi yoyenera kudera linalake.
Low Viscosity (LV) HPMC
Low mamasukidwe akayendedwe HPMC ali ndi otsika maselo kulemera ndipo mosavuta sungunuka m'madzi.Ndilo mtundu wamba wa HPMC ndipo umagwiritsidwa ntchito m'mafakitale osiyanasiyana kuphatikiza zakudya, zodzoladzola, zomangamanga ndi zamankhwala.LV HPMC ndiyabwino kwambiri pazogwiritsa ntchito zomwe zimafuna mayankho otsika mpaka apakatikati monga ma gels omveka bwino, ma emulsion ndi utoto.LV HPMC itha kugwiritsidwanso ntchito kukulitsa alumali moyo wazakudya, kuchepetsa syneresis ndikupereka mawonekedwe osalala.
LV HPMC imagwiritsidwanso ntchito nthawi zambiri pantchito yomanga kuti ipititse patsogolo magwiridwe antchito azinthu zopangira simenti monga matope, ma grouts ndi zomatira matailosi.Zimathandizira kuchepetsa kutaya kwa madzi mu zosakaniza za simenti, zimalepheretsa kusweka, ndikulimbitsa mgwirizano pakati pa zipangizo.LV HPMC imagwiritsidwanso ntchito kuonjezera mphamvu ndi kulimba kwa pulasitala, stucco ndi zinthu zina zokhudzana nazo.
Medium Viscosity (MV) HPMC
Sing'anga mamasukidwe akayendedwe HPMC ali apamwamba maselo kulemera kuposa LV HPMC ndipo nkomwe sungunuka m'madzi.Nthawi zambiri amagwiritsidwa ntchito pamakina omwe amafunikira mayankho okhazikika monga zokutira, ma varnish ndi inki.MV HPMC ili ndi kayendetsedwe kabwino ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe kake.MV HPMC itha kugwiritsidwanso ntchito pamitundu yambiri ya pH, ndikupereka kusinthasintha kowonjezera pazogwiritsa ntchito zosiyanasiyana.
MV HPMC imagwiritsidwanso ntchito kwambiri muzinthu zamankhwala, monga mapiritsi omasulidwa oyendetsedwa, chifukwa imachedwetsa kusungunuka ndipo motero imatalikitsa kutulutsa kwazinthu zogwira ntchito.
High Viscosity (HV) HPMC
Mkulu mamasukidwe akayendedwe HPMC ali apamwamba kwambiri maselo kulemera kwa magiredi onse atatu ndipo ndi osachepera madzi sungunuka.Amagwiritsidwa ntchito popanga zinthu zomwe zimafuna kukhuthala komanso kukhazikika, monga ma sauces, creams ndi gels.HV HPMC imathandizira kukulitsa mawonekedwe ndi kukhuthala kwa zinthu, kupereka mawonekedwe osangalatsa a ogwiritsa ntchito.Itha kugwiritsidwanso ntchito kukhazikika emulsions, kupewa kukhazikika komanso kukulitsa moyo wa alumali.Kuphatikiza apo, HV HPMC imagwiritsidwa ntchito nthawi zambiri m'makampani opanga mapepala kuti apange mphamvu zamapepala komanso kusindikiza.
Pomaliza
Kukhuthala koyenera kwa HPMC ndikofunikira kuti ikwaniritse magwiridwe antchito osiyanasiyana.LV HPMC ndiyoyenera kugwiritsa ntchito mapulogalamu omwe amafunikira njira zotsika kwambiri mpaka zapakatikati, pomwe MV HPMC ndi yoyenera kuyankha zokhuthala monga utoto, ma vanishi ndi inki.Pomaliza, HV HPMC ndiyabwino kugwiritsa ntchito zomwe zimafuna kukhuthala ndi kukhazikika monga zonona, ma gels ndi sosi.Kusankha mamasukidwe olondola kungathandize kukonza magwiridwe antchito a HPMC ndikupangitsa kuti ikhale yoyenera pamapulogalamu osiyanasiyana.
