Li-cellulose ethers ke lisebelisoa tse tloaelehileng tse sebelisoang ha ho etsoa lipente le liphahlo tse kang putty powder.Putty ke filler e entsoeng ka phofo e sebelisetsoang ho tlatsa likheo, mapetsong le masoba sebakeng sefe kapa sefe.Cellulose ether e ntlafatsa boleng ba phofo ea putty ka ho ntlafatsa ho khomarela, ho kopana le lintho tse ling tsa 'mele.Ha u khetha li-cellulose ethers bakeng sa putty powder, mehato e hlokahalang e lokela ho nkoa ho netefatsa sephetho sa boleng bo phahameng.
E fana ka tataiso e pharaletseng litabeng tse lokelang ho eloa hloko ha ho khethoa cellulose ether bakeng sa putty powder.
Tlhokomeliso #1: Fumana mofuta oa cellulose ether e hlokahalang
Ho na le mefuta e fapaneng ea li-cellulose ethers, ho kenyelletsa methylcellulose, ethylcellulose, hydroxyethylcellulose, hydroxypropylcellulose, le carboxymethylcellulose.Mofuta o mong le o mong oa cellulose ether o na le thepa e ikhethang e etsang hore e tšoanelehe bakeng sa lits'ebetso tse ikhethileng.Ka hona, pele u khetha ether ea cellulose bakeng sa phofo ea putty, hoa hlokahala ho fumana mofuta oa ether ea cellulose e loketseng mofuta oa putty phofo e hlahisoang.
Ka mohlala, hydroxyethyl cellulose (HEC) e loketse hantle bakeng sa tšebeliso ea li-putty powders hobane e ntlafatsa thepa ea rheological ea putty powder.HEC e tenya tharollo, e thibela ho fokotseha, 'me e eketsa viscosity ea phofo ea putty.Methylcellulose, ka lehlakoreng le leng, ha e tšoanelehe ho sebelisoa ka putty powder hobane ha e na thepa e teteaneng e tšoanang le ea HEC.
Tlhokomeliso #2: Etsa qeto ea hore na ke mofuta ofe oa cellulose ether o hlokahalang
Li-cellulose ethers li fumaneha ka limaraka tse fapaneng ho latela bohloeki le mahloriso.Letšoao la cellulose ether e hlokahalang bakeng sa putty powder e lokela ho khethoa ho ea ka litlhoko tsa putty powder.
Mefuta e phahameng ea bohloeki ba li-cellulose ethers li khethoa ho feta li-cellulose ethers tsa boemo bo tlaase hobane li netefatsa ts'ebetso e tsitsitseng ea putty powder.Ether e phahameng ea cellulose ether ha e na molora, masala le litšila tse ling tse amang boleng ba putty powder.
Tlhokomeliso ea #3: Ho Hlahloba ho qhibiliha ha Cellulose Ethers
Li-cellulose ethers li qhibiliha ka metsing, empa tekanyo ea ho qhibiliha e fapana ho ea ka mofuta oa cellulose ether.Hydroxypropylcellulose (HPC) ke mohlala oa cellulose ether e ke keng ea qhibiliha ka metsing;ho e-na le hoo, e qhalana habonolo metsing.
Ke habohlokoa ho tseba ho qhibiliha ha cellulose ether e sebelisoang ka putty powder ho etsa bonnete ba hore e qhibiliha habonolo ka metsing 'me ha e bake ho kopana kapa ho se lumellane ho putty powder.
Tlhokomeliso #4: Nahana ka Mocheso oa Kopo
Mocheso oa kaho oa putty powder cellulose ether le oona ke oa bohlokoa ho nahanoa.Mofuta o mong le o mong oa cellulose ether o na le mocheso o itseng oa mocheso oo o sebetsang hantle ho oona.Ka hona, ho bohlokoa ho khetha li-cellulose ethers tse ka mamellang mocheso oa kaho oa putty powder.
Cellulose ether e na le botsitso bo botle ba mocheso 'me e loketse ho sebelisoa ka putty powder hobane e ke ke ea senya kapa ea hlōleha ha mocheso o phahameng.Hydroxypropyl methylcellulose (HPMC) ke mohlala oa cellulose ether e tsitsitseng ka mocheso 'me e sebetsa hantle ka putty powder.
Tlhokomeliso #5: Lekola Maemo a Polokelo
Li-cellulose ethers li utloa ho fetoha ha mocheso le mongobo;ka hona, li tlameha ho bolokoa tlas'a maemo a khethehileng ho qoba ho senyeha.Li-cellulose ethers li lokela ho bolokoa sebakeng se omileng se nang le mocheso o laolehileng le mongobo ho netefatsa botsitso ba tsona.
Li-cellulose ethers tse tsitsitseng li ntlafatsa boleng ba putty powder, e etsa hore e be e tsitsitseng, e tšoarellang le e sebetsang.
Tlhokomeliso #6: Latela mehato ea polokeho
Nakong ea ts'ebetso ea tlhahiso, mehato e lokela ho nkoa ho thibela ho pepeseha ha basebetsi ho cellulose ethers.Ha u sebetsana le cellulose ethers, ho bohlokoa ho roala lisebelisoa tsa ts'ireletso tse kang liatlana, likhalase le lithebe tsa sefahleho ho qoba ho kopana le letlalo, mahlo kapa tsamaiso ea ho hema.
Ho feta moo, ho bohlokoa ho ngola linkho tse nang le li-cellulose ether tse nang le matšoao a lemosang a kotsi le ho latela mekhoa e nepahetseng ea ho lahla ho qoba tšilafalo ea tikoloho.
ha re phethela
Ho khetha ether e nepahetseng ea cellulose bakeng sa putty powder ho bohlokoa ho fumana liphetho tsa boleng bo holimo.Ho lokela ho nkoa mehato ea ho itlhokomela ha ho etsoa qeto ea mofuta le kereiti ea cellulose ether e hlokahalang, ho hlahloba ho qhibiliha ha eona le botsitso ba mocheso, ho khomarela maemo a loketseng a polokelo, le ho latela mehato ea tšireletso.
Ho nka litemoso tsena ha ho netefatse feela boleng ba phofo ea putty, empa hape ho sireletsa basebetsi le tikoloho.Ho sebelisa li-ethers tse nepahetseng tsa cellulose, putty powder e ka hlahisoa ka mokhoa o sireletsehileng le ka katleho ho finyella litlhoko tsa bareki bakeng sa boleng le botsitso.
