Ho qhibiliha ha Methyl Cellulose Products
Methyl cellulose ke polymer e qhibilihang ka metsing e sebelisoang haholo lits'ebetsong tse fapaneng tsa indasteri. Ho qhibiliha ha lihlahisoa tsa methyl cellulose ho ipapisitse le lintlha tse fapaneng, ho kenyelletsa tekanyo ea phetoho, boima ba limolek'hule, mocheso le pH.
Lihlahisoa tsa methyl cellulose tse nang le tekanyo e tlaase ea ho fetola le boima bo tlaase ba limolek'hule li qhibiliha haholoanyane metsing ho feta lihlahisoa tse nang le boemo bo phahameng ba ho fetola le boima bo phahameng ba limolek'hule. Lihlahisoa tsa methyl cellulose tse nang le tekanyo e phahameng ea ho fetola le boima bo phahameng ba limolek'hule li ka hloka mocheso o phahameng kapa nako e telele ea ho kopanya ho qhibiliha ka ho feletseng metsing.
PH ea tharollo e ka boela ea ama ho qhibiliha ha methyl cellulose. Lihlahisoa tsa methyl cellulose li qhibiliha haholo ka tharollo e sa nke lehlakore kapa e nang le asiti e nyane. Ho boleng bo phahameng ba pH, ho qhibiliha ha methyl cellulose hoa fokotseha. Sena se bakoa ke ionization ea lihlopha tsa hydroxyl mokokotlong oa cellulose, e ka fokotsang bokhoni ba limolek'hule tsa metsi ho sebelisana le liketane tsa polymer.
Ntle le metsi, lihlahisoa tsa methyl cellulose li ka boela tsa qhibiliha ka har'a metsoako e meng ea tlhaho e kang ethanol, methanol le acetone. Leha ho le joalo, ho qhibiliha ha methyl cellulose ho li-solvents tsena ho na le moeli 'me ho itšetlehile ka tekanyo ea ho kenya sebaka le boima ba limolek'hule tsa sehlahisoa.
Qetellong, ho qhibiliha ha lihlahisoa tsa methyl cellulose ho ipapisitse le lintlha tse fapaneng, ho kenyeletsoa boemo ba sebaka, boima ba limolek'hule, mocheso le pH. Lihlahisoa tsa methyl cellulose tse nang le tekanyo e tlaase ea ho fetola le boima bo tlaase ba limolek'hule li qhibiliha haholoanyane metsing, athe lihlahisoa tse nang le tekanyo e phahameng ea ho fetola le boima bo phahameng ba limolek'hule li ka hloka mocheso o phahameng kapa nako e telele ea ho kopanya ho qhibiliha ka ho feletseng. Lihlahisoa tsa methyl cellulose li qhibiliha ka ho fetisisa ka litharollo tse sa nke lehlakore kapa tse nang le asiti e nyane, hape li ka qhibiliha ka har'a lihlapolli tse ling tsa organic, empa ho qhibiliha ha solvents tsena ho na le moeli.
