Ntlafatso ea Rheological Thickener

Nts'etsopele ea li-thickeners tsa rheological, ho kenyeletsoa le tse thehiloeng ho li-ether tsa cellulose joalo ka carboxymethyl cellulose (CMC), e kenyelletsa motsoako oa ho utloisisa thepa ea rheological e lakatsehang le ho fetola sebopeho sa limolek'hule tsa polymer ho fihlela thepa eo. Mona ke kakaretso ea ts'ebetso ea nts'etsopele:

1. Litlhoko tsa Rheological: Mohato oa pele oa ho nts'etsapele rheological thickener ke ho hlalosa boemo ba rheological bo lakatsehang bakeng sa ts'ebeliso e reriloeng. Sena se kenyelletsa liparamente tse kang viscosity, boitšoaro ba ho fokotsa ho kuta, khatello ea chai, le thixotropy. Litšebeliso tse fapaneng li ka hloka litšobotsi tse fapaneng tsa rheological ho latela lintlha tse kang maemo a ts'ebetso, mokhoa oa ts'ebeliso, le litlhoko tsa ts'ebetso ea ho qetela.
2. Khetho ea Polymer: Hang ha litlhoko tsa rheological li hlalositsoe, li-polymer tse loketseng li khethoa ho latela thepa ea tsona ea rheological le ho lumellana le sebopeho. Li-ether tsa cellulose tse kang CMC hangata li khethoa ka lebaka la thepa ea tsona e ntle ea ho tenya, ho tsitsisa le ho boloka metsi. Boima ba limolek'hule, tekanyo ea ho nkeloa sebaka, le mokhoa oa ho nkeloa sebaka oa polymer li ka fetoloa ho latela boitšoaro ba eona ba rheological.
3. Ho Kopanya le ho Fetola: Ho latela thepa e lakatsehang, polymer e ka feta tlhahisong kapa phetohong ho fihlela sebopeho se lakatsehang sa limolek'hule. Mohlala, CMC e ka kopanngoa ka ho kopanya cellulose le chloroacetic acid tlas'a maemo a alkaline. Tekanyo ea phetolo (DS), e khethollang palo ea lihlopha tsa carboxymethyl ka yuniti ea glucose, e ka laoloa nakong ea tlhahiso ho fetola ho qhibiliha ha polymer, viscosity le katleho ea ho teteana.
4. Ntlafatso ea Tlhahiso: Setenya sa rheological se kenyelletsoa ka har'a motsoako ka tekanyo e loketseng ho fihlela viscosity e lakatsehang le boitšoaro ba rheological. Ntlafatso ea tlhahiso e ka kenyelletsa lintlha tse fetolang tse kang mahloriso a polymer, pH, letsoai, mocheso le sekhahla sa ho shapa ho ntlafatsa ts'ebetso ea ho shapa le botsitso.
5. Teko ea Tshebetso: Sehlahisoa se entsoeng se etsoa liteko tsa ts'ebetso ho lekola thepa ea sona ea rheological tlas'a maemo a fapaneng a amanang le ts'ebeliso e reriloeng. Sena se ka kenyelletsa litekanyo tsa viscosity, liprofaele tsa shear viscosity, khatello ea chai, thixotropy, le botsitso ha nako e ntse e ea. Teko ea ts'ebetso e thusa ho netefatsa hore rheological thickener e fihlela litlhoko tse boletsoeng 'me e sebetsa ka mokhoa o tšepahalang ts'ebelisong e sebetsang.
6. Ho Eketsa le ho Hlahisa: Hang ha tlhahiso e ntlafalitsoe 'me ts'ebetso e netefalitsoe, ts'ebetso ea tlhahiso e atolosoa bakeng sa tlhahiso ea khoebo. Lintlha tse kang ho tsitsa ha sehlopha ho ea ho sehlopha, botsitso ba shelefo, le katleho ea litšenyehelo li nahanoa nakong ea ho eketsa ho netefatsa boleng bo tsitsitseng le ho phela hantle moruong ha sehlahisoa.
7. Ntlafatso e Tsoelang Pele: Ntlafatso ea li-thickeners tsa rheological ke ts'ebetso e tsoelang pele e ka kenyelletsang ntlafatso e tsoelang pele e ipapisitseng le maikutlo a basebelisi ba ho qetela, tsoelo-pele ea saense ea polymer, le liphetoho litlhokong tsa 'maraka. Li-formulations li ka ntlafatsoa, ​​​​'me mahlale a macha kapa li-additives li ka kenyelletsoa ho ntlafatsa ts'ebetso, botsitso le ts'ebeliso e ntle ea litšenyehelo ha nako e ntse e ea.

Ka kakaretso, ntshetsopele ya di-thickeners tsa rheological e kenyeletsa mokhoa o hlophisehileng o kopanyang saense ya polymer, boiphihlelo ba ho etsa dihlahiswa le diteko tsa tshebetso ho etsa dihlahiswa tse fihlelang ditlhoko tse ikgethang tsa rheological tsa ditshebediso tse fapaneng.
