Ntlafatso ea hydroxethyl celluloulose

Ntlafatso eaHydroxeeyl cellulosese(Hec) Ho kenyelletsa ho sebetsa lisebelisoa tse tala ho ntlafatsa bohloeki ba eona, bo sa feleng, le thepa bakeng sa lits'ebetso tse tobileng. Kakaretso ea ts'ebetso ea HEC:

1. Khetho ea lintho tse tala:

Ts'ebetso ea ntlafatso e qala ka khetho ea spl ea boleng bo holimo e le thepa e tala. Clloulose e ka tsoa mehloling e fapaneng, joalo ka pulp ea lehong, thatton linces, kapa thepa e ngoe e thehiloeng ho limela.

2. Tlhoma:

Lintho tse tala tse tahiloeng li ntse li putlama litšila tse kang Lignin, Hemicellulose le likarolo tse ling tseo e seng tsa selefouso. Ts'ebetso ena ea tlhoekiso e akaretsang e kenyelletsa ho hlatsoa, ​​ho tšosoa le kalafo ea lik'hemik'hale, le phekolo ea lik'hemik'hale, le ho lema lik'hemik'hale, le phekolo ea lik'hemik'hale ho ntlafatsa bohloeki ba clluulose.

3. TLHOKOMELISO:

Kamora ho hloekisoa, cellulose e fetotsoe ka karolelano ea phallo ea hydroone, e fella ka hore ke hydroulose ea hydroythyl celdlese (hec). Liphetoho tsa menyetla hangata li kenyelletsa ts'ebeliso ea Alkali Metal Hydroxides le Ethylene kapa Ethylene chlorohydrin.

4. Nolofazation le ho hlatsoa:

Ho latela mookameli, motsoako oa karabelo o sa nke lehlakore ho tlosa alkali e feteletseng ebe u lokisa ph. Sehlahisoa se sa behelletsoeng se hlatsoitsoe ebe sea hlatsuoa ka botlalo ho tlosa lik'hemik'hale tse setseng ho tsoa karabelo.

5. Ho fifala le ho omisa:

Tharollo ea hec e hloekisitsoeng e se e hloekisoa ho tlosa likotoana kapa litlolo tse setseng. Kamora ho hloka fono, tharollo ea hec e ka ba e rarahane, haeba ho hlokahala, ebe e oma e omiloe ka phofo ea ho qetela kapa ea granular ea Hec.

6. Taolo ea boleng:

Ho pholletsa le ts'ebetso ea ntlafatso, mehato ea taolo ea boleng ba boleng e kenngoa ho netefatsa hore ho tla etsa hore ho tloaelehile, bohloeki le ts'ebetso ea sehlahisoa sa Hec. Liteko tsa taolo ea boleng li ka kenyelletsa tekanyo ea liketsahalo tsa pono, tlhahlobo ea kelello, mongobo oa li-mongoeng, mongobo oa li-mongobo le tlhahlobo e 'ngoe ea lik'hemik'hale le tsa lik'hemik'hale.

7. Ho paka le ho boloka:

Ha e se e hloekisitsoe, sehlahisoa sa hec se kenngoa lijana tse loketseng kapa mekotla ea polokelo le lipalangoang. Ho paka ka nepo ho thusa ho sireletsa hec ho tloha litšila, mongobo le lintho tse ling tsa tikoloho tse ka amang tšobotsi ea eona.

Likopo:

Hydroxethyl cellulosese (Hec) e fumana lits'ebetso tse 'maloa tsa boitlamo ba indasteri e fapaneng, ho kenyelletsa:

• Kaho: E sebelisoa e le mosirethi ea rheology mosireitsi le moemeli oa ho boloka metsi lihlahisoa tse thehiloeng sa lelapa
• Tlhokomelo ea Botho le Litseiti: E sebelisoa joalo ka thipa, lerabele, le filimi e ne e le ea pele ho hopola, litlolo, le lihlahisoa tse ling tsa tlhokomelo.
• PharmacEucal: E sebelisoa e le mojaro, ho senyeha, moemeli oa lokollotsoeng ka matlapeng, li-capsules le lisepa tsa molomo.
• Lijo: E sebelisoa e le bolo ea thickener, emmolifier le lihlahisoa tsa lijo tse kang batho ba ropesa litho, liaparo le lihlahisoa tsa lebese.

Phetha:

Nchafatso ea Hydroxethyl celdlosese (Hec) e kenyelletsa mehato e mengata ea ho hloekisa le maemo a fapaneng a marang-rang a joalo ka kaho, tlhokomelo ea motho le lijo. Ts'ebetso ea ntlafatso e tiisa hore e lumela, bohloeki le boleng ba sehlahisoa sa hec, nolofalletsa ho sebelisoa ha ona lifonong le lihlahisoa tse fapaneng.
