HPMC, dzina lathunthu ndi Hydroxypropyl Methylcellulose, ndi ether yopanda ionic cellulose yomwe imagwiritsidwa ntchito kwambiri pomanga, mankhwala, chakudya, mankhwala a tsiku ndi tsiku ndi zina.
1. Gulu ndi mamasukidwe akayendedwe
The mamasukidwe akayendedwe a HPMC ndi chimodzi mwa zinthu zofunika thupi, ndi HPMC ndi kukhuthala osiyana ali ndi kusiyana kwambiri ntchito. Ma viscosity osiyanasiyana amachokera ku viscosity yotsika (makumi a cps) mpaka kukhuthala kwakukulu (makumi masauzande a cps).
Low mamasukidwe akayendedwe HPMC: Childs ntchito ntchito amafuna Kutha mofulumira kapena flowability, monga suspensions madzi mankhwala, opopera, etc.
Yapakatikati mamasukidwe akayendedwe HPMC: chimagwiritsidwa ntchito tsiku ndi tsiku mankhwala, monga shampu, shawa gel osakaniza, etc., kupereka zolimbitsa thickening tingati ndi zabwino rheological katundu.
High mamasukidwe akayendedwe HPMC: makamaka ntchito zomangamanga, monga matope youma, zomatira matailosi ceramic, mkati ndi kunja khoma putty, etc., kupereka thickening kwambiri, kusunga madzi ndi katundu zomangamanga.
2. Kugawikana ndi mlingo wolowa m'malo
Kuchuluka kwa kusintha kwa HPMC kumatanthawuza kuchuluka kwa hydroxypropyl ndi methyl m'malo mwa molekyulu yake, yomwe nthawi zambiri imafotokozedwa ngati MS (hydroxypropyl degree of substitution) ndi DS (methyl substitution).
Otsika digiri ya m'malo HPMC: amasungunula mwamsanga ndipo makamaka ntchito zimene amafuna kusungunuka mofulumira, monga mankhwala ❖ kuyanika piritsi ndi zakumwa pompopompo.
Mkulu digiri ya m'malo HPMC: Ili ndi mamasukidwe akayendedwe apamwamba ndi kusungirako madzi bwino, ndipo ndi oyenera mankhwala amene amafuna mkulu mamasukidwe akayendedwe ndi kusungirako madzi mkulu, monga zomangira ndi zodzoladzola moisturizing ogwira kwambiri.
3. Kugawa ndi madera ogwiritsira ntchito
Kugwiritsiridwa ntchito kwapadera kwa HPMC m'magawo osiyanasiyana kumasiyana kwambiri, ndipo kungathe kugawidwa m'magulu otsatirawa malinga ndi magawo ogwiritsira ntchito:
zomangira
Ntchito yayikulu ya HPMC pantchito yomanga ndikuwongolera magwiridwe antchito komanso kulimba kwa zida, kuphatikiza:
Mtondo Wowuma: HPMC imapereka kusungirako bwino kwa madzi, kukhathamiritsa ndi magwiridwe antchito, kupititsa patsogolo ntchito yomanga komanso mtundu wazinthu zomalizidwa.
Zomatira matailosi: Wonjezerani mphamvu zomangirira komanso zotsutsana ndi kutsetsereka kuti mutsimikizire kukhazikika komanso kukhazikika kwa matailosi.
Utoto ndi putty: Limbikitsani rheology ndi kusunga madzi kwa utoto ndi putty kuti mupewe kusweka ndi kutayika kwa ufa.
mankhwala
Pazamankhwala, HPMC imagwiritsidwa ntchito makamaka ngati othandizira mankhwala, kuphatikiza:
Kupaka piritsi: Monga chotchinga chamapiritsi, chimapereka umboni wa chinyezi, kusungunula ndi kutulutsa kosalekeza kuti zitheke kukhazikika komanso mawonekedwe a mankhwalawa.
Gel: amagwiritsidwa ntchito popanga gel osakaniza mankhwala, kupereka zomatira zabwino ndi biocompatibility.
chakudya
HPMC amagwiritsidwa ntchito makamaka ngati thickener, emulsifier ndi stabilizer mu makampani chakudya, kuphatikizapo:
Zakudya Zakudya Zakudya Zakudya Zakudya Zakudya Zakudya Zakudya Zakudya Zakudya Zakudya Zakudya Zakudya Zakudya Zakudya Zakudya Zakudya Zakudya Zakudya Zakudya Zakudya Zakudya Zakudya Zakudya Zakudya Zakudya Zakudya Zakudya Zakudya Zakudya Zakudya Zakudya Zakudya Zambiri:
Zamkaka: Monga emulsifier ndi stabilizer, zimalepheretsa kusanja komanso kugwa kwa zinthu zamkaka ndikuwongolera kukhazikika kwazinthu.
Mankhwala atsiku ndi tsiku
Mu mankhwala tsiku lililonse, HPMC chimagwiritsidwa ntchito monga thickeners ndi stabilizers, kuphatikizapo:
Shampoo ndi gel osamba: Perekani kukhuthala kwapakati komanso rheology kuti muwongolere luso lazogwiritsa ntchito.
Zosamalira pakhungu: Monga chokhuthala komanso chonyowa, zimawonjezera kukhathamiritsa komanso luso lakugwiritsa ntchito kwa mankhwalawa.
4. Zolinga zina zapadera
HPMC itha kugwiritsidwanso ntchito m'magawo ena apadera, monga migodi yamafuta, mafakitale a ceramic, makampani opanga mapepala, etc.
Oilfield kupanga: amagwiritsidwa ntchito pobowola madzimadzi ndi fracturing madzi kupereka thickening kwambiri ndi kuchepetsa kutaya madzimadzi katundu.
Makampani a Ceramic: amagwiritsidwa ntchito ngati chomangira ndi kuyimitsa kuti apititse patsogolo kukhazikika komanso kusungunuka kwa ceramic slurry.
Makampani opanga mapepala: amagwiritsidwa ntchito pochiza mapepala kuti awonjezere mphamvu zake komanso kukana madzi.
Monga chotumphukira cha cellulose chamitundumitundu, HPMC ili ndi mawonekedwe abwino kwambiri amthupi ndi mankhwala komanso chiyembekezo chogwiritsa ntchito. Mitundu yosiyanasiyana ya HPMC ili ndi makhalidwe awoawo malinga ndi kukhuthala, digiri ya m'malo ndi ntchito. Kusankha mtundu woyenera wa HPMC molingana ndi zomwe mukufuna kugwiritsa ntchito kumatha kusintha kwambiri magwiridwe antchito ndi mtundu wazinthu. Ndi kupita patsogolo kwa sayansi ndi ukadaulo komanso kukulitsa madera ogwiritsira ntchito, kugwiritsa ntchito HPMC kudzakhala kokulirapo komanso mozama.
