Cellulose e sebelisoa haholo ho petrochemical, meriana, ho etsa pampiri, litlolo, thepa ea mohaho, joalo-joalo Ke tlatsetso e ngata haholo, 'me litšebeliso tse fapaneng li na le litlhoko tse fapaneng tsa ts'ebetso bakeng sa lihlahisoa tsa cellulose.
Sengoliloeng sena haholo-holo se kenyelletsa tšebeliso le mokhoa oa ho khetholla boleng ba HPMC (hydroxypropyl methylcellulose ether), mefuta e fapaneng ea cellulose e sebelisoang hangata ka phofo e tloaelehileng ea putty.
HPMC e sebelisa k'hothone e hloekisitsoeng joalo ka thepa ea mantlha e tala.E na le ts'ebetso e ntle, theko e phahameng le khanyetso e ntle ea alkali.E loketse putty e tloaelehileng e sa keneleng metsi le seretse sa polymer se entsoeng ka samente, lime calcium le lisebelisoa tse ling tse matla tsa alkaline.Sebaka sa viscosity ke 40,000-200000S.
E latelang ke mekhoa e mengata ea ho lekola boleng ba hydroxypropyl methylcellulose e akarelitsoeng ke Xiaobian bakeng sa hau.Tloo 'me u ithute le Xiaobian~
1. Bosoeu:
Ehlile, ntlha ea bohlokoa ea ho khetholla boleng ba hydroxypropyl methylcellulose e ke ke ea ba bosoeu feela.Baetsi ba bang ba tla eketsa mahlahana a bosoeu ts'ebetsong ea tlhahiso, tabeng ena, boleng bo ke ke ba ahloloa, empa bosoeu ba boleng bo phahameng ba hydroxypropyl methylcellulose bo hlile bo molemo.
2. Bokhabane:
Hydroxypropyl methylcellulose hangata e na le botle ba 80 mesh, 100 mesh le 120 mesh.Bokhabane ba likaroloana bo botle haholo, 'me ho qhibiliha le ho boloka metsi ho boetse ho molemo.Ena ke hydroxypropyl methylcellulose ea boleng bo holimo.
3. Phetiso ea leseli:
Kenya hydroxypropyl methylcellulose ka metsing ebe o e qhaqha ka metsing nako e itseng ho hlahloba viscosity le ponaletso.Ka mor'a hore gel e thehoe, hlahloba phetisetso ea khanya ea eona, ho ntlafatsa phetisetso ea leseli, ho phahamisa taba e sa tsitsang le bohloeki.
4. Matla a khoheli a khethehileng:
Ha matla a khoheli a itseng a le kholoanyane, a betere, hobane ha matla a khoheli a itseng a le boima haholo, a phahamisa litaba tsa hydroxypropyl methyl ho eona, ho boloka metsi ho betere.
