Nts'etsopele ea Rheological Thickener

Nts'etsopele ea li-thickeners tsa rheological e bile mohato oa bohlokoa nalaneng ea mahlale a thepa le boenjiniere.Rheological thickeners ke lisebelisoa tse ka eketsang viscosity le / kapa ho laola thepa ea ho phalla ha metsi, ho emisoa le li-emulsions.

Motsoako oa pele oa rheological thickener o ile oa fumanoa ka phoso lekholong la 19th, ha motsoako oa metsi le phofo o ne o tloheloa hore o eme nako e itseng, e leng se ileng sa fella ka ntho e teteaneng e kang gel.Motsoako ona hamorao o ile oa fumanoa e le ho fanyeha habonolo ha likaroloana tsa phofo ka metsing, tse neng li ka sebelisoa e le motenya litšebelisong tse fapaneng.

Mathoasong a lekholo la bo20 la lilemo, ho ile ha sibolloa hore thepa e ’ngoe e na le matla a ho teteana, a kang setache, marinini le letsopa.Lisebelisoa tsena li ne li sebelisoa e le li-thickeners tsa rheological mefuteng e fapaneng ea ts'ebeliso, ho tloha ho lijo le litlolo ho ea ho lipente le maro a ho cheka.

Leha ho le joalo, li-thickeners tsena tsa tlhaho li ne li na le mefokolo, joalo ka ts'ebetso e fapaneng, kutloisiso ea maemo a ts'ebetso, le ts'ilafalo e ka bang teng ea likokoana-hloko.Sena se ile sa lebisa ho hlahisoeng ha li-thickeners tsa maiketsetso tsa rheological, tse kang cellulose ethers, acrylic polymers, le polyurethanes.

Cellulose ethers, joalo ka sodium carboxymethyl cellulose (CMC), methyl cellulose (MC), le hydroxypropyl cellulose (HPC), e se e le e 'ngoe ea li-rheological thickeners tse sebelisoang haholo lits'ebetsong tse fapaneng, ka lebaka la thepa ea tsona e ikhethang, joalo ka ho qhibiliha ha metsi, pH botsitso, matla a ionic sensitivity, le bokhoni ba ho etsa lifilimi.

Tsoelo-pele ea li-thickeners tsa maiketsetso tsa rheological li nolofalitse ho etsoa ha lihlahisoa ka ts'ebetso e tsitsitseng, botsitso bo ntlafetseng, le ts'ebetso e ntlafetseng.Ka tlhokahalo e ntseng e hola ea lisebelisoa tse sebetsang hantle haholo, nts'etsopele ea li-rheological thickeners e lebelletsoe ho tsoela pele, e susumetsoang ke tsoelo-pele ea mahlale a thepa, k'hemistri le boenjiniere.
