EHEC le MEHEC

EHEC (ethyl hydroxyethyl cellulose) le MEHEC (methyl ethyl hydroxyethyl cellulose) ke mefuta e 'meli ea bohlokoa ea li-cellulose ethers tse sebelisoang hangata liindastering tse sa tšoaneng, ho akarelletsa le indasteri ea pente le ea ho roala. Ha re hlahlobeng e 'ngoe le e 'ngoe ka botebo:

1. EHEC (Ethyl Hydroxyethyl Cellulose):
   • Sebopeho sa Lik'hemik'hale: EHEC e tsoa ho cellulose ka ho hlahisa lihlopha tsa ethyl le hydroxyethyl mokokotlong oa cellulose.
   • Thepa le Mesebetsi:
     • EHEC e qhibiliha ka metsing 'me e etsa litharollo tse hlakileng, tse nang le viscous.
     • E sebetsa e le mofetoleli o teteaneng le oa rheology ka lipente le liphahlo tse thehiloeng metsing, ho laola viscosity le ho ntlafatsa thepa ea kopo.
     • EHEC e fana ka boitšoaro ba pseudoplastic kapa shear-thinning ho penta metsoako, ho bolelang hore viscosity e fokotseha ka sekhahla se ntseng se eketseha sa ho kuta, ho nolofatsa ts'ebeliso e bonolo le brushability e bonolo.
   • Lisebelisoa:
     • EHEC e sebelisoa haholo ka lipente tse ka hare le tsa ka ntle, li-primers le li-coatings ho finyella ho lumellana ho lakatsehang, ho phalla le ho leka-lekanya thepa.
     • E sebetsa ka ho khetheha ho li-formulation moo viscosity e phahameng ka litekanyetso tse tlaase tsa ho kuta e hlokahalang bakeng sa ho hanyetsa ho sag le ho ntlafatsoa ha filimi.
2. MEHEC (Methyl Ethyl Hydroxyethyl Cellulose):
   • Sebopeho sa Lik'hemik'hale: MEHEC ke ether ea cellulose e fetotsoeng e nang le methyl, ethyl, le hydroxyethyl substituents mokokotlong oa cellulose.
   • Thepa le Mesebetsi:
     • MEHEC e bonts'a solubility e tšoanang le thepa ea rheological ho EHEC empa e na le liphapang tse itseng ts'ebetsong.
     • E fana ka bokhoni bo ntlafetseng ba ho boloka metsi ha bo bapisoa le EHEC, e leng se etsang hore e tšoanelehe ka ho khetheha bakeng sa ho etsoa ha nako e atolositsoeng e bulehileng kapa ntlafatso ea mebala e ntlafetseng e lakatsehang.
     • MEHEC e fana ka ts'ebetso e matlafalitsoeng ea botenya le botsitso holim'a mefuta e mengata ea pH le maemo a mocheso.
   • Lisebelisoa:
     • MEHEC e fumana ts'ebetso lipenteng tse thehiloeng metsing, lirafshoa le thepa ea kaho moo ho hlokahalang ho boloka metsi, ho teteaneng le ho laola rheological.
     • E atisa ho sebelisoa ha ho etsoa lipente tse khabisitsoeng, liphahlo tse entsoeng ka letsoho, le li-finishing tse khethehileng moo nako e telele ea ho sebetsa le thepa e ntlafetseng ea phallo e leng ea bohlokoa.

Ka bobeli EHEC le MEHEC ke li-ether tsa cellulose tse tenyetsehang tse fanang ka li-formumulators ho feto-fetoha ha maemo ho fihlela litšoaneleho tse lakatsehang tsa ts'ebetso lipenteng le lipente tse thehiloeng metsing. Ho lumellana ha tsona le li-additives tse ling, boiketlo ba ho kenyelletsoa ho etsoa, ​​le bokhoni ba ho ntlafatsa thepa ea bohlokoa e kang ho laola viscosity, ho boloka metsi, le lisebelisoa tsa kopo li etsa hore e be likarolo tsa bohlokoa ha ho etsoa liaparo tsa boleng bo phahameng ba mekhabiso.
