Hydroxethyl Cellulose E sebelisoa haholo indastering e fapaneng e kang meriana, litlolo, lipere, lipapatso le lihlahisoa tsa lijo ka lebaka la ho tsitsisa, ho tsitsipana le ho boloka metsi. Leha ho le joalo, ho buisana ka boleng ba PH ea Hec ho hloka kutloisiso e pharaletseng ea thepa ea eona, sebopeho le likopo.
Ho utloisisa hydroxethyl cellulose (hec):
1. KHOTSO EA CHEMAMER:
Hec o kenella ke maikutlo a Cellulose ka ponts'o ea mylene
Tekanyo ea sebaka (DS) e bua ka palo e tloaelehileng ea lihlopha tsa hydroyethyl ka sehlopha sa glucose ka kemiso ea Hc. Boleng bo phahameng ba DS boa lebisa ho lanyollo ea metsi le pono e tlase.
2. Thepa:
Hec o qhibiliha metsing le ho etsa tharollo e hlakileng, e etsang hore e be e loketseng likopo tse fapaneng tse hlokang litlhare tse pepeneneng.
E bontša boitšoaro ba pseudorial, e bolelang hore lipono tsa eona li fokotse ka tlasa khatello ea kelello, e lumella ho sebelisa kopo e bonolo le ho sebetsana le eona.
Litaba tsa tharollo ea hec li susumetsoa ke lintho tse hloahloa, mocheso, pH le ho ba teng ha letsoai kapa li-bloding tse ling.
3. Likopo:
Pharmaceutical: hec e sebelisoa e le tlheketla le hlorisoang ke kalafo ea meriana le e kholo ea meriana le lihlooho tse kang litlolo, lisente le likaranta.
Li-cosmetics: Ke motsoako o tloaelehileng ho lihlahisoa tsa tlhokomelo ho kenyeletsoa shampoos, lithaba le thepa ea eona e matlafatsang.
Li-peta le lipuisano: hec e eketsoa ho peta, bosholu ba taolo, ntlafatsang thepa ea phallo, mme e ntlafatsa sebopeho sa lifilimi.
Indasteri ea lijo: Lihlahisoa tsa lijo, hec e sebeletsang e le motho ea hlohloang, le emulifier linthong tse kang liso tsa masoha, liaparo le lihlahisoa tsa lebese.
boleng ba hydroxethyl celdoulose (Hec):
1. Ph Regingence:
PH ea tharollo e nang le hec e ka susumetsa boitšoaro ba eona le ts'ebetso ea lits'ebetso tse fapaneng.
Ka kakaretso, hec e tsitsitse ho phallo e pharaletseng, hangata pakeng tsa ph 2 le ph 12. Liteko tse boima li ka ama thepa ea eona le botsitso.
2. Liphetho tsa Viscosity:
Litaba tsa tharollo ea hec li ka its'epahalla tsebo, haholo-holo ka boleng bo phahameng kapa bo tlase.
Haufi le pH ea ho se nke lehlakore (PH 5-8), hangata li bonts'a pono ea bona e phahameng.
Ha e le boleng bo tlase haholo kapa bo phahameng haholo
3. Phetoho ea PH:
Ka lipheo tsa nako ea pH li hlokahala, hangata li-buffers li sebelisoa ho boloka mofuta o tsebahalang oa pH.
Li-buffger tse tloaelehileng tse kang li-buffer tsa citrate kapa tsa phosphate li tsamaisana le hec le ho thusa ho tsitsisa thepa ea eona mabapi le mofuta o itseng oa pH.
4. LITLHAKISO TSA BOTSOANG:
Ma-fordilator o tlameha ho nka ts'ebetso ea PH ea Hec e nang le lisebelisoa tse ling ka sebopeho.
Maemong a mang, ho etsa liphetoho ph ea foromo ea sebopeho ho ka hlokahala ho ntlafatsa ts'ebetso ea hec.
Hydroxethyl celdloulose (Hec) ke polymer ea feto-fetohang e nang le likopo tse ngata ho indastering e fapaneng. Le ha mosebetsi oa eona o tsitsitse ka kakaretso ka kakaretso o matlafala haholo, PH e fetelletseng e ka ama ts'ebetso ea eona le botsitso. Ho utloisisa pH ho hlokahala hore a tsebe lihlahisoa tsa lihlahisoa tse sebetsang le tse tsitsitseng ho meriana, litlolo, lipere, lipere tsa lijo. Ka ho nahana ka ts'ebetso ea PH le ho hira mekhoa e nepahetseng ea ho etsa, hec e ka tsoela pele ho sebeletsa e le motsoako oa bohlokoa likolong tse fapaneng.
