Mtengo wa HPMC
HPMC Hydroxypropyl Methyl Cellulose
Chidule cha mankhwala
HPMC ndi semi-synthetic nonionic cellulose yosakaniza ether yomwe nthawi zambiri imawoneka ngati ufa woyera kapena woyera. Zimakonzedwa ndi kusintha kwa mankhwala a cellulose achilengedwe.
Kusungunuka kwamadzi bwino: Itha kusungunuka mwachangu m'madzi ozizira kuti ipange njira yowonekera yowonekera.
Makhalidwe a mankhwala
Kukhuthala kwabwino kwambiri: Kuwongolera kwambiri kukhuthala komanso kusasinthika kwamadzimadzi, kumapangitsa kuti madzi azikhala okhazikika komanso okhazikika.
Mapangidwe abwino kwambiri a filimu: Mukaumitsa, filimu yolimba imapangidwa, yomwe imakhala yosagonjetsedwa ndi madzi, yopuma komanso yosinthasintha.
Kugwirizana kwabwino kwachilengedwe: Zopanda poizoni, zopanda pake, zosakwiyitsa, zoyenera kumunda wa biomedicine.
Zowonongeka zachilengedwe: Zowonongeka mwachilengedwe m'chilengedwe, mogwirizana ndi zofunikira zoteteza chilengedwe chobiriwira.
kugwiritsa ntchito mankhwala
Makampani omanga: Amagwiritsidwa ntchito ngati chosungira madzi ndi kubweza matope a simenti kuti apititse patsogolo kufalikira ndi nthawi yogwira ntchito; Monga zomatira, zimagwiritsidwa ntchito kuyika zinthu zokongoletsera monga matailosi ndi mabulosi.
Makampani okutira: Monga thickener, dispersant ndi stabilizer, kusintha ntchito zokutira.
Pharmaceutical munda: Itha kugwiritsidwa ntchito ngati ? kuyanika filimu zinthu, kupitiriza kumasulidwa wothandizila, kapisozi zipolopolo zakuthupi, kuyimitsidwa thandizo, etc.
Makampani azakudya: Kuchita ngati thickener, emulsifier, stabilizer ndi maudindo ena.
Njira yopanga
Kawirikawiri thonje, matabwa monga zipangizo, mwa alkalization, propylene okusayidi ndi chloromethane etherification ndondomeko kukonzekera.
Zoyembekeza za msika
Ndi chitukuko cha zachuma padziko lonse ndi chidziwitso cha chilengedwe, kufunikira kwake kwa msika kukupitirira kukula. Kugwiritsa ntchito m'nyumba zobiriwira, zokutira zoteteza chilengedwe, biomedicine ndi magawo ena akupitilira kukula, ndipo msika ukuyembekezeka kukulirakulira. Koma panthawi imodzimodziyo, makampaniwa akukumananso ndi zovuta zamakono zamakono, mpikisano wamsika komanso zofunikira zoteteza chilengedwe.
gwiritsani ntchito njira zodzitetezera
Pogwiritsira ntchito, m'pofunika kumvetsera njira yowonongeka, ndikusankha njira yoyenera yowonongeka malinga ndi zitsanzo zosiyanasiyana. Panthawi imodzimodziyo, tcherani khutu kuzinthu zosungirako, ziyenera kuikidwa pamalo owuma, oyera ozizira kuti atsimikizire khalidwe la mankhwala ndi ntchito.
