Pampiri ea filter- Bakeng sa ho boloka sampole
Mokguba oa kabo ea mangolo- Bakeng sa ho lekanya boholo ba metsi
Mohloli oa khatello- Ho pepeta metsi a mangata (mohlala, mochine o mongata oa selemo o mongata kapa boima)
Timer- ho latela nako ea tekanyetso ea ho boloka metsi
Thermostat kapa incubator- Ho boloka mocheso oa liteko (hangata ka mocheso oa kamore, hoo e ka bang 20-25 ° C.
4.Tsamaiso
Ho hlophisoa ha mohlala:
E boima ba palo e tsebahalang ea phofo ea cellulose ether (hangata ligrama tse peli) ka nepo.
Kopanya cellulose Ether ea phofo ka metsi a lekaneng (mohlala, 100 ml) ho theha slurry kapa paste. Hlohlelletsa motsoako ka botlalo ho netefatsa ho lahla lintho le hrydration.
Lumella motsoako ho hydrate bakeng sa nako ea metsotso e 30 ho netefatsa ho ruruha ka botlalo ea Cellulo More.
Seta sa lisebelisoa tsa ho boloka metsi:
Lokisetsa lisebelisoa tsa ho boloka metsi ka ho beha pampiri ea filthara ka setsing sa lifilimi kapa ka har'a sena.
Tšela slurry ea cellulose ether ho pampiri ea filter 'me e netefatsa hore e hasana le eona.
Tekanyo ea ho boloka thepa:
Etsa kopo khatello ho sampole e ka bang ka letsoho kapa ka ho sebelisa mochine o mongata oa selemo. Palo ea khatello e lokela ho lekana liteko tsohle.
Lumella sistimi ho tsoa metsotso e 5-10, nakong eo metsi a mangata a tla arohana le ho thehoa.
Bokella metsi a tlhotsoeng a setloholo seriti se fumaneng seithuti sa mangolo.
Lipalo tsa ho boloka metsi:
Kamora hore ts'ebetso e behang e phethe, e be boima metsi a bokelletsoeng ho bona hore na metsi a lahlehile.
Bala ho thibela metsi ka metsing ka ho tlosa palo ea metsi a mahala ho tloha ka tekanyo ea pele ea metsi e sebelisitsoeng ka motsoako oa mohlala.
Ho Phekolosisa:

Ho Boloka Nako Hoa Nako:Maemong a mang, ho boloka metsi ho ka lekantsoe ka linako tse fapaneng (Mop, 5, 10, metsotso e 15) Ho utloisisa lik'hiloki tsa metsi.
Ho boloka mocheso:Liteko tse tsamaisoang ka lithemparetjha tse fapaneng li ka bontša hore na mocheso o ama joang ho boloka metsi, haholo bakeng sa lisebelisoa tse hlokolosi.
7.Lintlha tse amang metsi a boloka metsi
Ho na le mabaka a 'maloa a ka susumetsang ho boloka metsi a li-cellulose ethe ea' nete:
Viscosity:E-bang e-ba-e-e-'na le selefoue e nang le pono e phahameng e tloaetse ho boloka metsi a mangata.
Boima ba Molecular:Boholo ba linoko tse phahameng tsa linoko tsa cellulose li na le bokhoni bo ntlafalitsoeng ba metsi ka lebaka la sebopeho sa bona se seholo sa limolek'hule.
Degree of Shahameng:Likhatiso tsa lik'hemik'hale tsa bo-'mè tsa cellulose (mohlala, tekanyo ea methylation kapa hydroxypropylation) e ka ama thepa ea bona ea metsi.
TLHOKOMELISO EA CONYULAD Ether ka motsoako:Lerato le phahameng la Cellulo Smel e fella ka mokhoa o nepahetseng oa metsi.
8.Lethathamo la sampole: Liphetho tsa mohlala
| Mofuta oa sampole | Metsi a pele (ML) | Bokelloa ka metsi (ml) | Ho Boloka Meea (%) |
| Methylcellllll (MC) | 100 | 70 | 30% |

Mohleng ena, melao-motheo ea ho boloka metsi e bontša hore celboxymethyl celbolothyl Sampole e na le ho bolokoa ka metsing, ha methylxlulose e le tlase haholo.
Teko ea ho boloka metsi ho ba-Esters ea Cellulose ke mokhoa oa ho laola bokhoni ho lekanya bokhoni ba lisebelisoa tsena ho tšoara metsi. Liphetho li re thusa hore motho a na le boikarabelo ba 'mele oa khekhe e khethehileng, joalo ka likopi tse khethehileng tsa taolo ea mongobo li mpefatsa. Ka ho lekannong ts'ebetso ea liteko, bahlahisi ba ka netefatsa ts'ebetso e sa fetoheng ea lihlahisoa tsa bona tsa Cellulo Smelulo 'me u fane ka lintlha tse sebetsang bakeng sa nts'etsopele ea sehlahisoa.
