Hydroxypropyl methylcellulose (HPMC ka bokhutšoane) ke ether ea bohlokoa e tsoakiloeng, e leng polima e se nang ionic e qhibilihang ka metsing, 'me e sebelisoa haholo lijong, meriana, indasteri ea lik'hemik'hale tsa letsatsi le letsatsi, ho roala, ho itšoara ka polymerization le kaho e le ho emisa ho qhalakanngoa , ho teteaneng, emulsifying, stabilizing le adhesives, joalo-joalo, 'me ho na le lekhalo le leholo' marakeng oa malapeng.
Hobane HPMC e na le thepa e babatsehang e kang ho teteaneng, emulsification, ho etsa filimi, colloid e sireletsang, ho boloka mongobo, ho khomarela, ho hanyetsa enzyme le ho se sebetse ha metabolism, e sebelisoa haholo ka ho koahela, ho etsa polymerization, thepa ea mohaho, tlhahiso ea oli, masela, lijo, meriana, Li-ceramics tse sebelisoang letsatsi le letsatsi, lisebelisoa tsa elektroniki le peo ea temo le mafapha a mang.
Blisebelisoa tsa ho sebetsa
Ka thepa ea moaho, HPMC kapa MC hangata e eketsoa samente, seretse le seretse ho ntlafatsa thepa ea kaho le ho boloka metsi.
HPMC e ka sebelisoa ho:
1). Sekhomaretsi le sekhomaretsi bakeng sa tepi ea sekhomaretsi e thehiloeng ho gypsum;
2). Ho kopanya litene, lithaele le metheo e entsoeng ka samente;

Indasteri ea pente
Indastering ea pente, HPMC e sebelisoa haholo ka pente ea latex le likaroloana tsa pente ea resin e qhibilihang ka metsi e le moemeli oa ho etsa lifilimi, motenya, emulsifier le stabilizer.
Ho emisa Polymerization ea PVC
Tšimo e nang le tšebeliso e kholo ka ho fetisisa ea lihlahisoa tsa HPMC naheng ea heso ke ho emisoa ha polymerization ea vinyl chloride. Ka ho emisoa ha polymerization ea vinyl chloride, tsamaiso ea ho hasana e ama ka ho toba boleng ba sehlahisoa sa PVC resin le ts'ebetso ea eona le lihlahisoa; e ka ntlafatsa botsitso ba mocheso oa resin le ho laola kabo ea boholo ba likaroloana (ke hore, fetola boima ba PVC). Palo ea HPMC e nka 0.025% ~ 0.03% ea tlhahiso ea PVC.
Resin ea PVC e lokiselitsoeng ke HPMC ea boleng bo holimo, ntle le ho netefatsa hore ts'ebetso e kopana le maemo a naha, e boetse e na le thepa e ntle ea 'mele, litšobotsi tse ntle tsa likaroloana le boitšoaro bo botle ba ho qhibiliha ha rheological.

Liindasteri tse ling haholo-holo li kenyelletsa litlolo, tlhahiso ea oli, litlolo, lirafshoa tsa ka tlung le liindasteri tse ling.
We qhibilihang ka metsing
HPMC ke e 'ngoe ea li-polymer tse qhibilihang ka metsing,' me ho qhibiliha ha eona metsing ho amana le litaba tsa sehlopha sa methoxyl. Ha litaba tsa sehlopha sa methoxyl li le tlase, li ka qhibiliha ka alkali e matla 'me ha e na ntlha ea gelation ea thermodynamic. Ka keketseho ea dikahare tsa methoxyl, e ameha haholo ho ruruha ha metsi mme e qhibiliha ka alkali e hlapollang le alkali e fokolang. Ha dikahare tsa methoxyl di> 38C, di ka qhibidiha ka metsing, mme di ka boela tsa qhibidiha ka dihydrocarbon tse halogenated. Haeba asiti ea nakoana e eketsoa ho HPMC, HPMC e tla hasana ka potlako metsing ntle le ho hlahisa lintho tse sa keneng tsa kaka. Sena se bakoa haholo ke taba ea hore acid ea periodic e na le lihlopha tsa dihydroxyl sebakeng sa ortho ho glycogen e qhalakaneng.
