Cellulose e sebelisoa haholo ho petrochemical, meriana, ho etsa pampiri, litlolo, thepa ea kaho, jj. Ke sehlomathiso se feto-fetohang haholo, 'me tšebeliso e fapaneng e na le litlhoko tse fapaneng tsa ts'ebetso bakeng sa lihlahisoa tsa cellulose.
Sengoloa sena se hlahisa haholo-holo mokhoa oa ts'ebeliso le oa ho khetholla boleng ba HPMC (hydroxypropyl methylcellulose ether), mofuta oa cellulose o sebelisoang haholo phofong e tloaelehileng ea putty.
HPMC e sebelisa k'hothone e hloekisitsoeng e le thepa e ka sehloohong e tala. E na le ts'ebetso e ntle, theko e holimo le khanyetso e ntle ea alkali. E loketse putty e tloaelehileng e sa keneleng metsi le seretse sa polymer se entsoeng ka samente, calcium ea lime le lisebelisoa tse ling tse matla tsa alkaline. Sebaka sa viscosity ke 40,000-200000S.
Tse latelang ke mekhoa e 'maloa ea ho leka boleng ba hydroxypropyl methylcellulose e akaretsoang ke Xiaobian bakeng sa hau. Tloo u ithute ka Xiaobian~
1. Bosweu:
Ehlile, ntlha ea bohlokoa ho khethoeng ha boleng ba hydroxypropyl methylcellulose e ke ke ea e-ba bosweu feela. Bahlahisi ba bang ba tla eketsa metsoako ea ho soeufatsa ts'ebetsong ea tlhahiso, tabeng ena, boleng bo ke ke ba ahloloa, empa bosweu ba hydroxypropyl methylcellulose ea boleng bo holimo bo botle haholo.
2. Botle:
Hangata Hydroxypropyl methylcellulose e na le botenya ba letlooeng la 80, letlooeng la 100 le letlooeng la 120. Botenya ba likaroloana bo botle haholo, 'me ho qhibiliha le ho boloka metsi le tsona li ntle. Ena ke hydroxypropyl methylcellulose ea boleng bo holimo.
3. Phetiso ea leseli:
Kenya hydroxypropyl methylcellulose ka metsing 'me u e qhale ka metsing ka nako e itseng ho hlahloba ho hlaka le ho pepeneneng. Kamora hore gel e thehoe, hlahloba phetisetso ea eona ea leseli, phetisetso ea leseli e betere, le ho feta ha lintho tse sa qhibiliheng le bohloeki.
4. Matla a khoheli a itseng:
Ha matla a khoheli a itseng a le maholo, ho molemo, hobane ha matla a khoheli a itseng a le boima, ke moo hydroxypropyl methyl e leng ngata, ho boloka metsi ho ba betere.
