Sehlopha sa Lihlahisoa tsa Methyl Cellulose

Lihlahisoa tsa Methyl cellulose (MC) li ka aroloa ho latela lintlha tse fapaneng tse kang kereiti ea bona ea viscosity, degree of substitution (DS), boima ba limolek'hule le ts'ebeliso.Mona ke likarolo tse ling tse tloaelehileng tsa lihlahisoa tsa methyl cellulose:

1. Sehlopha sa Viscosity:
   • Lihlahisoa tsa methyl cellulose hangata li aroloa ho latela limaraka tsa tsona tsa viscosity, tse lumellanang le viscosity ea tsona ka tharollo ea metsi.The viscosity ea methyl cellulose solutions hangata e lekanngoa ka centipoise (cP) ka mahloriso a itseng le mocheso.Limaraka tse tloaelehileng tsa viscosity li kenyelletsa viscosity e tlase (LV), viscosity e bohareng (MV), viscosity e phahameng (HV), le viscosity e phahameng haholo (UHV).
2. Degree of Substitution (DS):
   • Lihlahisoa tsa methyl cellulose le tsona li ka hlophisoa ho ipapisitsoe le boemo ba tsona ba phetisetso, e bolelang palo e tloaelehileng ea lihlopha tsa hydroxyl ho unit ea glucose e nketsoeng sebaka ke lihlopha tsa methyl.Litekanyetso tse phahameng tsa DS li bonts'a boemo bo boholo ba ho fetola 'me hangata bo fella ka ho qhibiliha ho hoholo le mocheso o tlase oa gelation.
3. Boima ba Molek'hule:
   • Lihlahisoa tsa methyl cellulose li ka fapana ka boima ba limolek'hule, tse ka amang thepa ea tsona e kang solubility, viscosity, le gelation behavior.Lihlahisoa tse phahameng tsa limolek'hule tsa methyl cellulose li atisa ho ba le viscosity e phahameng le thepa e matla ea gelling ha e bapisoa le lihlahisoa tse tlaase tsa boima ba limolek'hule.
4. Mephato e khethehileng ea kopo:
   • Lihlahisoa tsa methyl cellulose le tsona li ka aroloa ho latela ts'ebeliso ea tsona e reriloeng.Mohlala, ho na le limaraka tse ikhethileng tsa methyl cellulose e ntlafalitsoeng bakeng sa litlhare tsa meriana, lihlahisoa tsa lijo, thepa ea kaho, lisebelisoa tsa tlhokomelo ea motho le lits'ebetso tse ling tsa indasteri.Likereiti tsena li kanna tsa ba le thepa e hlophisitsoeng ho fihlela litlhoko tsa likopo tsa tsona tse fapaneng.
5. Mephato e Ikgethileng:
   • Lihlahisoa tse ling tsa methyl cellulose li etselitsoe lits'ebetso tse ikhethileng kapa li na le thepa e ikhethang e etselitsoeng ts'ebeliso e itseng.Mehlala e kenyelletsa li-derivatives tsa methyl cellulose tse nang le botsitso bo matlafalitsoeng ba mocheso, thepa e ntlafetseng ea ho boloka metsi, litšobotsi tse laoloang tsa tokollo, kapa ho lumellana le li-additives kapa li-solvents tse itseng.
6. Mabitso a Khoebo le Lihlahisoa:
   • Lihlahisoa tsa methyl cellulose li ka rekisoa ka mabitso a fapaneng a khoebo kapa lihlahisoa ke bahlahisi ba fapaneng.Lihlahisoa tsena li kanna tsa ba le thepa e ts'oanang empa li ka fapana ho ea ka lintlha, boleng le ts'ebetso.Mabitso a tloaelehileng a khoebo bakeng sa methyl cellulose a kenyelletsa Methocel®, Cellulose Methyl, le Walocel®.

Lihlahisoa tsa methyl cellulose li ka aroloa ho latela lintlha tse kang viscosity grade, degree of substitution, boima ba molek'hule, limaraka tse khethehileng tsa kopo, limaraka tse khethehileng, le mabitso a khoebo.Ho utloisisa likarolo tsena ho ka thusa basebelisi ho khetha sehlahisoa se nepahetseng sa methyl cellulose bakeng sa litlhoko le lits'ebetso tsa bona.
