Li-ether tsa cellulose ke metsoako e tloaelehileng e sebelisoang tlhahisong ea pente le lipente tse kang phofo ea putty. Putty ke setlatsetso se thehiloeng phofong se sebelisetsoang ho tlatsa likheo, mapetso le masoba holim'a bokaholimo bofe kapa bofe. Cellulose ether e ntlafatsa boleng ba phofo ea putty ka ho ntlafatsa ho khomarela ha eona, ho momahana ha eona le thepa e meng ea 'mele. Ha ho khethoa li-ether tsa cellulose bakeng sa phofo ea putty, mehato e hlokahalang ea ho itšireletsa e lokela ho nkuoa ho netefatsa sephetho sa boleng bo holimo.
E fana ka tataiso e felletseng mabapi le litaba tse lokelang ho elwa hloko ha ho kgethwa ether ya cellulose bakeng sa phofo ya putty.
Tlhokomeliso #1: Fumana mofuta oa ether ea cellulose e hlokahalang
Ho na le mefuta e fapaneng ea li-ether tsa cellulose, ho kenyeletsoa methylcellulose, ethylcellulose, hydroxyethylcellulose, hydroxypropylcellulose, le carboxymethylcellulose. Mofuta o mong le o mong oa ether ea cellulose o na le thepa e ikhethang e etsang hore e lokele lits'ebetso tse itseng. Ka hona, pele o khetha ether ea cellulose bakeng sa phofo ea putty, ho hlokahala hore ho khethoe mofuta oa ether ea cellulose e loketseng mofuta oa phofo ea putty e hlahisoang.
Mohlala, hydroxyethyl cellulose (HEC) e loketse hantle ho sebelisoa phofong ea putty hobane e ntlafatsa thepa ea rheological ea phofo ea putty. HEC e tebisa tharollo, e thibela ho thekesela, 'me e eketsa viscosity ea phofo ea putty. Ka lehlakoreng le leng, methylcellulose ha e lokele ho sebelisoa phofong ea putty hobane ha e na thepa e tšoanang ea ho tenya le HEC.
Tlhokomeliso #2: Fumana hore na ether ea cellulose e hlokahala hakae
Li-ether tsa cellulose li fumaneha ka mefuta e fapaneng ho latela bohloeki le mahloriso. Mofuta oa ether ea cellulose o hlokahalang bakeng sa phofo ea putty o lokela ho khethoa ho latela litlhoko tsa phofo ea putty.
Mekhahlelo ea bohloeki bo phahameng ba li-ether tsa cellulose e khethoa ho feta li-ether tsa cellulose tsa boemo bo tlase hobane li netefatsa ts'ebetso e tsitsitseng ea phofo ea putty. Ether ea cellulose e hloekileng bo phahameng ha e na molora, masala le litšila tse ling tse amang boleng ba phofo ea putty.
Tlhokomeliso #3: Ho Lekola ho Qhibiliha ha Cellulose Ethers
Li-ether tsa cellulose lia qhibiliha ka metsing, empa tekanyo ea ho qhibiliha e fapana ho latela mofuta oa ether ea cellulose. Hydroxypropylcellulose (HPC) ke mohlala oa ether ea cellulose e sa qhibiliheng ka metsing; ho e-na le hoo, e hasana habonolo ka metsing.
Ho bohlokoa ho fumana hore na ether ea cellulose e sebelisoang phofong ea putty e qhibiliha hakae ho netefatsa hore e qhibiliha habonolo metsing 'me ha e bake ho kopana kapa ho se tsitse ha phofo ea putty.
Tlhokomeliso #4: Nahana ka Mocheso oa Kopo
Mocheso oa kaho oa phofo ea putty le cellulose ether le oona ke oa bohlokoa. Mofuta o mong le o mong oa ether ea cellulose o na le mocheso o itseng oo o sebetsang hantle ho oona. Ka hona, ho bohlokoa ho khetha li-ether tsa cellulose tse ka mamellang mocheso oa kaho oa phofo ea putty.
Cellulose ether e na le botsitso bo botle ba mocheso mme e loketse ho sebediswa ka hara phofo ya putty hobane e ke ke ya senyeha kapa ya hloleha maemong a lehodimo a phahameng. Hydroxypropyl methylcellulose (HPMC) ke mohlala wa ether ya cellulose e tsitsitseng mochesong mme e sebetsa hantle ka hara phofo ya putty.
Tlhokomeliso #5: Hlahloba Maemo a Polokelo
Li-ether tsa cellulose lia utloa bohloko liphetohong tsa mocheso le mongobo; ka hona, li lokela ho bolokoa tlas'a maemo a itseng ho qoba ho senyeha. Li-ether tsa cellulose li lokela ho bolokoa sebakeng se omileng se nang le mocheso le mongobo o laoloang ho netefatsa botsitso ba tsona.
Li-ether tsa cellulose tse tsitsitseng li ntlafatsa boleng ba phofo ea putty, e leng se etsang hore e be e tsitsitseng haholoanyane, e tšoarellang le e sebetsang hantle.
Temoso #6: Latela mehato ea tšireletso
Nakong ea ts'ebetso ea tlhahiso, mehato ea ho itšireletsa e lokela ho nkuoa ho thibela basebetsi ho pepesehela li-ether tsa cellulose. Ha ho sebetsoa li-ether tsa cellulose, ho bohlokoa ho roala lisebelisoa tse sireletsang tse kang liatlana, likhalase tsa mahlo le lithebe tsa sefahleho ho qoba ho kopana le letlalo, mahlo, kapa tsamaiso ea ho hema.
Ho phaella moo, ho bohlokwa ho ngola mabitso a dijana tse nang le di-ether tsa cellulose ka matshwao a temoso a kotsi a loketseng le ho latela mekgwa e nepahetseng ya ho lahla ho qoba tshilafatso ya tikoloho.
ha re phethela
Ho kgetha ether e nepahetseng ya cellulose bakeng sa phofo ya putty ho bohlokwa bakeng sa ho fumana diphetho tsa boleng bo hodimo. Ho hlokahala hore ho nkuwe mehato ya ho ela hloko ha ho kgethwa mofuta le kereiti ya ether e hlokahalang ya cellulose, ho lekolwa ho qhibiliha ha yona le botsitso ba mocheso, ho kgomarela maemo a nepahetseng a polokelo, le ho latela mehato ya ho ela hloko polokeho.
Ho nka mehato ena ea ho itšireletsa ha ho netefatse feela boleng ba phofo ea putty, empa hape ho sireletsa basebetsi le tikoloho. Ho sebelisa li-ether tse nepahetseng tsa cellulose, phofo ea putty e ka hlahisoa ka mokhoa o sireletsehileng le o sebetsang hantle ho fihlela litlhoko tsa bareki tsa boleng le botsitso.
