HPMC ke motsoako o sebelisoang hangata ho sebelisoa lits'ebetsong tse fapaneng tsa indasteri le tsa meriana. HPMC, eo hape e tsejoang e le hydroxypropyl methylcellulose, e tsoa ho cellulose, polima ea tlhaho e hlahisoang ke limela. Motsoako ona o fumanoa ka ho phekola cellulose ka lik'hemik'hale tse kang methanol le propylene oxide. Thepa e ikhethang ea HPMC e etsa hore e be khetho e tsebahalang mafapheng a fapaneng.
Ho na le mefuta e fapaneng ea HPMC, e 'ngoe le e 'ngoe e na le thepa le lits'ebetso tse ikhethang.
1. HPMC e le motenya
HPMC ho pharaletseng sebelisoa liindasteri tse sa tšoaneng e le thickener. HPMC e tenya maro 'me e fana ka sebopeho se boreleli' me ka hona e sebelisoa hangata ho lotion, litlolo le lihlahisoa tse ling tsa tlhokomelo ea letlalo indastering ea litlolo. Thepa e teteaneng ea HPMC e boetse e na le thuso indastering ea lijo e le sebaka sa li-thickeners tsa setso tse kang cornstarch. Indastering ea kaho, HPMC e sebelisoa e le ntho e tiisang lihlahisoa tse thehiloeng ho samente joalo ka li-grouts le caulks. Thepa e teteaneng ea HPMC e etsa hore e be e loketseng ho sebelisoa lihlahisoa tse hlokang sebopeho se tsitsitseng.
2. HPMC e le sekhomaretsi
HPMC e boetse e sebelisoa e le sekhomaretsi liindastering tse sa tšoaneng. Indastering ea lijo, HPMC e sebelisoa e le setlamo sa lihlahisoa tsa nama joalo ka lisoseje le li-burgers. HPMC e kopanya nama hammoho, e e fa sebopeho se ts'oanang le ho e thibela ho oela nakong ea ho pheha. Indastering ea meriana, HPMC e sebelisoa e le setlamo sa matlapa. HPMC e netefatsa hore matlapa a lula a tiile 'me ha a arohane ha a nooa ka molomo. Ho feta moo, HPMC e na le phello e tsitsitseng ea tokollo, e bolelang hore e thusa ho lokolla metsoako e sebetsang ka har'a letlapa butle-butle ka nako, ho netefatsa liphello tse tšoarellang nako e telele.
3. HPMC e le moemeli oa ho etsa lifilimi
HPMC e boetse e sebelisoa e le moemeli oa ho etsa lifilimi liindastering tse fapaneng. Ka indasteri ea lijo, HPMC e sebelisoa ho etsa filimi e sireletsang lijong tse kang litholoana le meroho ho thibela ho senyeha. HPMC e boetse e thibela lijo ho khomarelana, ho etsa hore ho be bonolo ho li tšoara le ho li paka. Ka indasteri ea meriana, HPMC e sebelisetsoa ho etsa lifilimi holim'a matlapa, ho li sireletsa le ho netefatsa hore metsoako e sebetsang e sirelelitsoe tikolohong. HPMC e boetse e sebelisoa indastering ea litlolo ho etsa filimi e sireletsang letlalong, e thibela ho lahleheloa ke mongobo le ho boloka letlalo le le metsi nako e telele.
4. HPMC joalo ka moemeli ea emisang
HPMC e boetse e na le thepa ea levitating, e etsa hore e be e loketseng ho sebelisoa liindasteri tse fapaneng. Ka indasteri ea ho roala, HPMC e sebelisoa e le moemeli ea emisang ho thibela likarolo tse fapaneng tsa liphahlo hore li se ke tsa arohana. HPMC e boetse e thusa ho laola viscosity ea pente, ho netefatsa hore e ata ka thelelo le ka ho lekana holim'a metsi. Ka indasteri ea meriana, HPMC e sebelisoa e le moemeli oa ho emisa bakeng sa lithethefatsi tse metsi. HPMC e thibela metsoako e sebetsang ka har'a sethethefatsi hore e se ke ea lula botlaaseng ba setshelo, ho etsa bonnete ba hore moriana o ajoa ka ho lekana ebile o sebetsa hantle.
5. HPMC bakeng sa lisebelisoa tsa hydrophilic
HPMC e boetse e sebelisoa lits'ebetsong tsa hydrophilic. Sebopeho sa hydrophilic sa HPMC se bolela hore e hohela le ho boloka mongobo, e etsa hore e be e loketseng ho sebelisoa libakeng tse fapaneng. Ka indasteri ea meriana, HPMC e sebelisoa e le moemeli oa hydrophilic ho netefatsa hore lithethefatsi li kenngoa habonolo ke 'mele. HPMC e boetse e sebelisoa indastering ea litlolo ho thusa ho boloka mongobo oa letlalo. Ka indasteri ea kaho, HPMC e sebelisoa e le moemeli oa hydrophilic ho ntlafatsa ho tšoarella le matla a konkreite.
ha re phethela
HPMC ke motsoako o sebetsang ka bongata o nang le lits'ebetso tse ngata liindastering tse fapaneng. Ho utloisisa mefuta e fapaneng ea HPMC le ts'ebeliso ea eona ho ka re thusa ho utloisisa bohlokoa ba lik'hemik'hale tsena bophelong ba rona ba letsatsi le letsatsi. HPMC ke mokhoa o bolokehileng, o sebetsang hantle le o se nang tikoloho ho feta metsoako ea khale ea lik'hemik'hale, e etsang hore e be khetho e tsebahalang bakeng sa lits'ebetso tse fapaneng tsa indasteri le tsa bongaka.
