Lintlha tse Susumetsang Boitšoaro ba Carboxymethyl Cellulose (CMC) Tharollo

Carboxymethyl cellulose (CMC) ke polymer e qhibilihang ka metsi e nkiloeng ho selulose e nang le lisebelisoa tse fapaneng liindastering tse fapaneng, ho kenyeletsoa lijo, meriana, litlolo le pampiri. Boitšoaro ba litharollo tsa CMC bo ka susumetsoa ke lintlha tse 'maloa, ho kenyelletsa ho tsepamisa maikutlo, boima ba limolek'hule, tekanyo ea ho fetola, pH, mocheso le maemo a ho kopanya. Ho utloisisa lintlha tsena ho bohlokoa bakeng sa ho ntlafatsa ts'ebetso ea CMC lits'ebetsong tse fapaneng. Sengoliloeng sena, re tla tšohla lintlha tsa bohlokoa tse susumetsang boits'oaro ba tharollo ea CMC.

Ho tsepamisa maikutlo

Khatello ea CMC tharollong e ka ama boitšoaro ba eona haholo. Ha mahloriso a CMC a ntse a eketseha, viscosity ea tharollo le eona e ea eketseha, e etsa hore e be e hlakileng haholoanyane le e fokolang haholo. Thepa ena e etsa litharollo tse phahameng tsa CMC tse loketseng lits'ebetso tse hlokang phello e teteaneng kapa ea gelling, joalo ka lijong le litlolo.

Boima ba Molek'hule

Boima ba limolek'hule tsa CMC ke ntlha e 'ngoe ea bohlokoa e ka amang boitšoaro ba eona. Boima bo phahameng ba limolek'hule CMC e atisa ho ba le thepa e ntle ea ho etsa lifilimi 'me e sebetsa hantle ho ntlafatsa thepa ea rheological ea tharollo. E boetse e fana ka bokhoni bo betere ba ho boloka metsi le ho ntlafatsa thepa e tlamang ea tharollo. Leha ho le joalo, boima bo phahameng ba limolek'hule CMC e ka 'na ea e-ba thata ho qhaqha, e etsa hore e se ke ea tšoaneleha bakeng sa lisebelisoa tse itseng.

Degree of Substitution

The degree of substitution (DS) ea CMC e bolela tekanyo ea carboxymethylation ea mokokotlo oa cellulose. E ka susumetsa haholo boitšoaro ba tharollo ea CMC. DS e phahameng e fella ka ho qhibiliha ho holimo le matla a ho boloka metsi a ntlafetseng, e leng se etsang hore e tšoanelehe bakeng sa lisebelisoa tse hlokang matla a mangata a ho boloka metsi, joalo ka lijo le meriana. Leha ho le joalo, DS CMC e phahameng e ka boela ea fella ka ho eketseha ha viscosity, e ka fokotsang ts'ebeliso ea eona lits'ebetsong tse itseng.

pH

PH ea tharollo ea CMC le eona e ka ama boitšoaro ba eona. CMC ka tloaelo e tsitsitse ka ho se nke lehlakore ho alkaline pH range, 'me viscosity ea tharollo e phahameng ka ho fetisisa pH ea 7-10. Ka pH e tlase, ho qhibiliha ha CMC hoa fokotseha, 'me viscosity ea tharollo le eona ea fokotseha. Boitšoaro ba litharollo tsa CMC bo boetse bo na le kutloelo-bohloko ho liphetoho pH, tse ka amang solubility, viscosity, le gelation thepa ea tharollo.

Mocheso

Thempereichara ea tharollo ea CMC e ka boela ea ama boitšoaro ba eona. The solubility ea CMC e eketseha ka mocheso, 'me mocheso o phahameng o ka fella ka viscosity e phahameng le bokhoni bo betere ba ho boloka metsi. Leha ho le joalo, mocheso o phahameng o ka boela oa baka tharollo ea gel, e leng ho etsang hore ho be thata ho sebetsa le eona. Mocheso oa mocheso oa CMC o ipapisitse le lintlha tse 'maloa, ho kenyeletsoa mahloriso, boima ba limolek'hule, le boemo ba ho nka sebaka.

Ho Kopanya Maemo

Maemo a motsoako oa tharollo ea CMC a ka boela a ama boitšoaro ba eona. Lebelo, nako, le mocheso oa motsoako li ka ama tsohle ho qhibiliha, viscosity le thepa ea gelation ea tharollo. Lebelo le phahameng la ho kopanya le mocheso li ka fella ka viscosity e phahameng le bokhoni bo betere ba ho boloka metsi, ha nako e telele ea ho kopanya e ka fella ka ho hasana ho molemo le ho tšoana ha tharollo. Leha ho le joalo, ho kopanya ho feteletseng ho ka boela ha baka tharollo ea gel, ho etsa hore ho be thata ho sebetsa le eona.

Qetello

Boitšoaro ba litharollo tsa CMC bo susumetsoa ke lintlha tse 'maloa, ho kenyelletsa ho tsepamisa maikutlo, boima ba limolek'hule, tekanyo ea ho fetola, pH, mocheso le maemo a ho kopanya. Ho utloisisa lintlha tsena ho bohlokoa bakeng sa ho ntlafatsa ts'ebetso ea CMC lits'ebetsong tse fapaneng. Ka ho laola lintlha tsena, hoa khonahala ho lokisa boits'oaro ba tharollo ea CMC ho fihlela litlhoko tse ikhethileng tsa lits'ebetso tse fapaneng, joalo ka botenya, ho tlotsa, ho tlama kapa ho boloka metsi.
