Hydroxypropyl methylcellulose, e tsejoang hape e le HPMC, ke ether ea cellulose e seng ea ionic e fumanoang k'hothoneng e hloekisitsoeng, thepa ea tlhaho ea polymer, ka letoto la lits'ebetso tsa lik'hemik'hale. Ke phofo e tšoeu kapa e mosehla hanyane e qhibilihang habonolo metsing. A re bueng ka mokhoa oa ho qhibiliha oa hydroxypropyl methylcellulose.
1. Hydroxypropyl methylcellulose e sebediswa haholoholo e le sehlomathiso bakeng sa phofo ya putty, seretse le sekhomaretsi. Ha e eketswa seretseng sa samente, e ka sebediswa e le ntho e bolokang metsi le e thibelang ho eketsa ho pompa; ha e eketswa phofong ya putty le sekhomaretsi, e ka sebediswa e le sehokelo. E le ho ntlafatsa ho ata le ho eketsa nako ya tshebetso, re nka Qingquan Cellulose e le mohlala ho hlalosa mokhoa wa ho qhala ha hydroxypropyl methylcellulose.
2. Hydroxypropyl methylcellulose e tloaelehileng e hlohlelletsoa pele ebe e hasana ka metsi a chesang, ebe e eketsoa ka metsi a batang, e hlohlelletsoa ebe e phodisoa hore e qhibilihe;
Ka ho khetheha: nka 1/5-1/3 ea metsi a chesang a hlokahalang, hlohlelletsa ho fihlela sehlahisoa se ekelitsoeng se ruruhile ka botlalo, ebe u eketsa karolo e setseng ea metsi a chesang, e ka bang metsi a batang kapa esita le metsi a leqhoa, 'me u hlohlelletse mochesong o loketseng (10°C) ho fihlela o qhibiliha ka botlalo.
3. Mokhoa oa ho kolobisa di-solvent tsa tlhaho:
Halaletsa hydroxypropyl methylcellulose ka har'a solvent ea tlhaho kapa u e kolobise ka solvent ea tlhaho, ebe u eketsa kapa u eketsa metsi a batang ho e qhala hantle. Solvent ea tlhaho e ka ba ethanol, ethylene glycol, jj.
4. Haeba ho kopana kapa ho phuthela ho etsahala nakong ea ho qhibiliha, ke hobane ho hlohlelletsa ho sa lekana kapa mohlala o tloaelehileng o eketsoa ka ho toba metsing a batang. Nakong ena, hlohlelletsa kapele.
5. Haeba dipululana di hlahiswa nakong ya ho qhibiliha, di ka tlohelwa dihora tse 2-12 (nako e ikgethang e itshetlehile ka ho tsitsa ha tharollo) kapa tsa tloswa ka ho hlwekisa ka vacuum cleaner, ho hatella, jj., kapa ho eketsa tekanyo e loketseng ya sehlahiswa sa ho hlwekisa.
Mehato ya tlhokomelo
Hydroxypropyl methylcellulose e arotsoe ka mefuta e qhibilihang butle le e qhibilihang hang-hang. Hydroxypropyl methylcellulose e ka qhibiliha ka ho toba ka metsing a batang.
