Ka nako ena, hydroxypropyl methylcellulose (HPMC) le eona e ka qhaloa hantle.
5. Tšebeliso e ka sehloohong ea hydroxypropyl methylcellulose (HPMC):
Hydroxypropyl methylcellulose (HPMC) e ka sebelisoa e le ntho e teteaneng, ea dispersant, emulsifier le e etsang filimi. Lihlahisoa tsa eona tsa boemo ba indasteri li ka sebelisoa lik'hemik'hale tsa letsatsi le letsatsi, lisebelisoa tsa elektronike, li-resin tsa maiketsetso, tsa kaho le tsa ho roala.
1. Ho emisa polymerization:
Ha ho etsoa li-resin tsa maiketsetso tse kang polyvinyl chloride (PVC), polyvinylidene chloride le li-copolymers tse ling, polymerization ea ho emisoa e sebelisoa hangata mme hoa hlokahala ho tsitsisa ho emisoa ha hydrophobic monomers ka metsing. Joalo ka polymer e qhibilihang ka metsi, lihlahisoa tsa hydroxypropyl methylcellulose (HPMC) li na le ts'ebetso e ntle haholo ea holim'a metsi 'me li sebetsa e le moemeli oa tšireletso ea colloidal, e ka thibelang ka katleho ho bokellana ha likaroloana tsa polymer. Ho feta moo, le hoja hydroxypropylmethylcellulose (HPMC) e le polymer e qhibilihang ka metsing, e boetse e qhibiliha hanyenyane ho li-monomers tsa hydrophobic 'me e eketsa porosity ea monomers eo likaroloana tsa polymeric li hlahisoang ho tsona, e le hore e ka fana ka li-polymers tse nang le bokhoni bo botle ba ho tlosa li-monomer tse setseng. le ho matlafatsa ho monngoa ha li-plasticizers.
2. Ha ho etsoa thepa ea mohaho, hydroxypropyl methylcellulose (HPMC) e ka sebelisoa bakeng sa:
1). Sekhomaretsi le sekhomaretsi bakeng sa tepi ea sekhomaretsi e thehiloeng ho gypsum;
2). Ho kopanya litene, lithaele le metheo e entsoeng ka samente;
3). stucco e entsoeng ka polasetiki;
4). samente ea sebopeho sa samente;
5). Ka mokhoa oa ho penta le ho tlosa pente.
