Liaparo tse entsoeng ka cellulose li fumane botumo bo bongata liindastering tse fapa-fapaneng ka lebaka la tlhaho ea tsona ea botsoalle, ho feto-fetoha ha maemo, le litšobotsi tse ntle tsa ts'ebetso.Leha ho le joalo, ho khetha selulose e ntle ka ho fetisisa bakeng sa ts'ebetso ea ho roala e ka ba mosebetsi o boima, ha ho nahanoa ka mefuta e mengata e fapaneng ea li-cellulose tse fumanehang.Sengoliloeng sena se ikemiselitse ho fana ka tataiso e felletseng mabapi le mokhoa oa ho khetha selulose e loketseng ka ho fetisisa bakeng sa merero ea ho roala, ho nahanoa ka lintlha tse fapaneng tse kang ts'ebetso, thepa le litlhoko tsa kopo.
Ho utloisisa Cellulose le Metsoako ea eona:
Cellulose ke polima ea tlhaho e fumanehang ka bongata maboteng a lisele tsa semela.E entsoe ka li-unit tsa glucose tse hokahaneng, tse etsang liketane tse telele.Li-derivatives tsa cellulose li fumanoa ka ho fetola sebopeho sa selulose ka mekhoa ea lik'hemik'hale.Li-derivatives tse tloaelehileng tsa cellulose tse sebelisoang liphahlo li kenyelletsa methyl cellulose (MC), hydroxypropyl cellulose (HPC), hydroxyethyl cellulose (HEC), le carboxymethyl cellulose (CMC), har'a tse ling.
Lintlha tse lokelang ho nahanoa ha u khetha Cellulose bakeng sa ho roala:
Mosebetsi: Etsa qeto ea karolo e itseng le thepa e lakatsehang ea selulose mofuteng oa ho roala.Ka mohlala, haeba ho roala ho hloka thepa e teteaneng le ho boloka metsi, methyl cellulose (MC) kapa hydroxyethyl cellulose (HEC) e ka ba khetho e nepahetseng.Haeba ho ntlafala ho khomarela ho hlokahala, carboxymethyl cellulose (CMC) kapa hydroxypropyl cellulose (HPC) e ka ba e loketseng haholoanyane.
Viscosity le Rheology: Nahana ka viscosity e lakatsehang le boitšoaro ba rheological ba ho roala.Li-derivatives tse fapaneng tsa cellulose li bonts'a mefuta e fapaneng ea ho teteana le ho phalla.Khetho e lokela ho ipapisa le mokhoa o lakatsehang oa kopo, joalo ka sefafatsi, borashe kapa rolara, hammoho le botenya bo lakatsehang le litšoaneleho tsa boemo.
Solubility le Compatibility: Lekola ho qhibiliha ha lintho tse tsoang ho cellulose tsamaisong e khethiloeng ea ho roala.Metsoako e meng e qhibiliha ka metsing, ha e meng e hloka metsoako ea tlhaho bakeng sa ho qhibiliha.Ho bohlokoa ho etsa bonnete ba ho lumellana lipakeng tsa derivative ea cellulose le likarolo tse ling tsa sebopeho sa ho roala ho qoba litaba tsa ho lumellana kapa karohano ea mekhahlelo.
Tlhahiso ea Lifilimi le ho Adhesion: Lekola bokhoni ba ho etsa filimi ea cellulose le tlatsetso ea eona mekhoeng ea ho khomarela.Li-derivatives tse ling tsa cellulose li na le bokhoni bo botle ba ho etsa lifilimi 'me li ka ntlafatsa ho khomarela ha seaparo ho substrate.
Khanyetso ea Lik'hemik'hale le Tikoloho: Nahana ka thepa ea ho hanyetsa e hlokahalang bakeng sa kopo e khethehileng ea ho roala.Lintho tse fapaneng tse tsoang ho cellulose li fana ka khanyetso e fapaneng ea lik'hemik'hale, mahlaseli a UV, mongobo le ho fetoha ha mocheso.Ho bohlokoa ho khetha motsoako oa selulose o fanang ka ts'ireletso le ts'ireletso e hlokahalang bakeng sa ts'ebeliso e reriloeng ea ho roala.
Tumellano ea Taolo: Netefatsa hore motsoako o khethiloeng oa cellulose o lumellana le melaoana e amehang ea indasteri, joalo ka e mabapi le bophelo bo botle, polokeho le maemo a tikoloho.Batla litifikeiti le litumello tse netefatsang ho nepahala ha motsoako oa cellulose bakeng sa lits'ebetso tsa ho roala.
Litšenyehelo le ho ba Teng: Lekola katleho ea litšenyehelo le boteng ba motsoako oa cellulose.Nahana ka litšenyehelo tse akaretsang tsa ho etsa, ho kenyeletsoa motsoako oa selulose, ha o ntse o netefatsa hore e fihlela litlhoko tse lakatsehang tsa ts'ebetso.Ho fumaneha le mehloli ea phepelo e tšepahalang le eona e lokela ho nahanoa bakeng sa tlhahiso e sa sitisoeng.
Ho khetha selulose e ntle ka ho fetisisa bakeng sa lits'ebetso tsa ho roala ho hloka ho shebisisa ka hloko lintlha tse kang ts'ebetso, viscosity, solubility, sebopeho sa filimi, thepa ea ho hanyetsa, ho latela melao, litšenyehelo, le ho fumaneha.Ka ho hlahloba lintlha tsena le ho li hokahanya le litlhoko tse khethehileng tsa ho etsoa ha litlolo, motho a ka khetha motsoako o loketseng oa Yibang oa cellulose o ntlafatsang ts'ebetso, ho tšoarella le boleng ba kakaretso ba tsamaiso ea ho roala.Qeto e nang le tsebo e nepahetseng mabapi le khetho ea selulose ea Yibang e kenya letsoho ho atlehile ho kenya likopo liindastering tse fapaneng.
