Hydroxypropyl methylcellulose (HPMC) ndi wamba semi-synthetic cellulose yochokera kumadera ambiri azamankhwala, zomangamanga, chakudya ndi zina.
(1) Makhalidwe oyambira a HPMC
HPMC ndi ufa woyera umene umasungunuka m'madzi kuti ukhale ndi viscous colloidal solution. Ili ndi zomatira zabwino, kukhazikika komanso kukhuthala, ndipo imatha kupanga filimu yowonekera. The katundu HPMC zimadalira mlingo wa methylation ndi hydroxypropylation, kotero pali specifications osiyana ndi ntchito.
(2) Malo ogwiritsira ntchito ndikugwiritsa ntchito HPMC
1. Makampani opanga mankhwala
a. Monga chonyamulira mankhwala komanso kumasulidwa kosalekeza
HPMC nthawi zambiri imagwiritsidwa ntchito ngati wothandizira wokhazikika pokonzekera mankhwala. M'mapiritsi ndi makapisozi, HPMC imatha kupanga filimu yokhazikika ndikuwongolera kuchuluka kwa kutulutsidwa kwa mankhwala. Ikagwiritsidwa ntchito, HPMC imasakanizidwa ndi zosakaniza za mankhwala. Pambuyo pa mapiritsi kapena kudzaza kapisozi, HPMC imatha kumasula mankhwalawo m'matumbo am'mimba.
b. Monga binder
Popanga mapiritsi, HPMC imagwiritsidwa ntchito ngati chomangira. Mukasakaniza ndi zinthu zina, zimatha kupititsa patsogolo mphamvu ndi kukhazikika kwa piritsi.
c. Monga wothandizira kuyimitsa
Mu mankhwala amadzimadzi, HPMC imatha kuletsa zosakaniza za mankhwalawa kuti zisakhazikike, potero kusunga kufanana kwa mankhwalawa.
2. Makampani omanga
a. Monga thickener kwa matope simenti
Pomanga, HPMC imagwiritsidwa ntchito kusakaniza simenti, mchenga ndi zida zina kuti zithandizire kumamatira ndikumanga kwamatope. Ikhoza kupititsa patsogolo kasungidwe ka madzi mumatope ndikuletsa kuti isaume msanga, potero kuwonjezera nthawi yogwira ntchito yamatope.
b. Monga chowonjezera cha zomatira matailosi
HPMC itha kugwiritsidwa ntchito ngati chowonjezera cha zomatira matailosi kuonjezera zomatira ndi ntchito yomanga zomatira ndikuletsa njerwa kuti zisagwe.
3. Makampani opanga zakudya
a. Monga thickener chakudya ndi stabilizer
HPMC nthawi zambiri ntchito monga thickener chakudya, monga jams, jellies ndi zakumwa. Ikhoza kuonjezera mamasukidwe akayendedwe a mankhwala ndi kusunga bata la mankhwala.
b. Monga chakudya filimu kale
HPMC angagwiritsidwe ntchito popanga chakudya ma CD filimu kupanga mandala filimu kuteteza chakudya.
4. Makampani Odzola
a. Monga thickener kwa zodzoladzola
HPMC amagwiritsidwa ntchito mu zodzoladzola, monga oyeretsa nkhope, zopakapaka khungu, etc., monga thickener kusintha kapangidwe ndi bata la mankhwala.
b. Monga filimu yakale
HPMC ikhoza kupanga filimu yowonekera ndipo imagwiritsidwa ntchito ngati filimu yakale muzinthu zosamalira khungu, monga masks amaso.
(3) Kusamala pakugwiritsa ntchito HPMC
Kusungunuka
Kusungunuka kwa HPMC kumakhudzidwa ndi kutentha ndi kugwedezeka kwa zinthu. Onetsetsani kuti chisakanizocho chikugwedezeka mofanana panthawi ya kusungunuka kuti musagwirizane.
Kuwongolera malingaliro
Sinthani kuchuluka kwa HPMC molingana ndi zomwe mukufuna. Mu mankhwala kukonzekera, kwambiri ndende zingakhudze kumasulidwa mlingo wa mankhwala; mu zipangizo zomangira, kuyika kochepa kwambiri kungayambitse kusagwira ntchito mokwanira.
Zosungirako
HPMC iyenera kusungidwa pamalo owuma, ozizira, kupewa kutentha ndi chinyezi kuti ikhale yokhazikika komanso yogwira mtima.
Kugwirizana
Mukamagwiritsa ntchito HPMC, kuyanjana kwake ndi zosakaniza zina kuyenera kuganiziridwa, makamaka mukamagwiritsa ntchito mankhwala osokoneza bongo ndi zakudya, kuonetsetsa kuti palibe zoyipa zomwe zimachitika.
HPMC ndi yosunthika yochokera ku cellulose yokhala ndi ntchito zambiri. Kuchokera pazamankhwala kupita ku zomangamanga, chakudya kupita ku zodzoladzola, mawonekedwe apadera a HPMC amapangitsa kuti izikhala ndi gawo lofunikira pazinthu zosiyanasiyana. Mukaigwiritsa ntchito, ndikofunikira kusankha zofananira ndi kuyika kwake molingana ndi zomwe mukufuna kugwiritsa ntchito, ndikulabadira kusungunuka kwake komanso momwe zimasungidwira kuti zitsimikizire kugwira ntchito komanso kukhazikika kwazinthuzo.
