Ukuthuthukiswa kwe-Rheological Thickener

Ukuthuthukiswa kwe-rheological thickeners kube yingqopha-mlando ebalulekile emlandweni wesayensi yezinto zokwakha kanye nobunjiniyela.I-Rheological thickeners yizinto ezingakhulisa i-viscosity kanye/noma zilawule izakhiwo zokugeleza koketshezi, ukumiswa, nama-emulsion.

I-thickener yokuqala ye-rheological yatholakala ngengozi ngekhulu le-19, lapho ingxube yamanzi nofulawa iyekwa ime isikhathi esithile, okuholela entweni ewugqinsi, efana nejeli.Kamuva le ngxube yatholakala iwukulengiswa okulula kwezinhlayiya zikafulawa emanzini, okwakungase kusetshenziswe njengesithako ekusetshenzisweni okuhlukahlukene.

Ekuqaleni kwekhulu lama-20, kwatholakala ukuthi ezinye izinto zinamandla okujiya, njengesitashi, izinsini nobumba.Lezi zinto zazisetshenziswa njenge-rheological thickeners ezinhlobonhlobo zezinhlelo zokusebenza, kusukela ekudleni nezimonyo kuya kumapende kanye noketshezi lokumba.

Kodwa-ke, lezi zingqimba zemvelo zinemikhawulo, njengokusebenza okuguquguqukayo, ukuzwela ezimweni zokucubungula, kanye nokungcoliswa okungenzeka kwe-microbiological.Lokhu kwaholela ekuthuthukisweni kokuqina kokwenziwa kwe-rheological, njengama-cellulose ethers, ama-polymer e-acrylic, nama-polyurethanes.

Ama-cellulose ethers, afana ne-sodium carboxymethyl cellulose (CMC), i-methyl cellulose (MC), kanye ne-hydroxypropyl cellulose (HPC), asephenduke enye yezinto ezisetshenziswa kakhulu ukushuba kwe-rheological ekusetshenzisweni okuhlukahlukene, ngenxa yezakhiwo zabo eziyingqayizivele, njengokuncibilika kwamanzi, Ukuzinza kwe-pH, ukuzwela kwamandla e-ionic, nekhono lokwenza ifilimu.

Ukuthuthukiswa kokuqina kokwenziwa kwe-rheological kwenze ukuthi ukwakhiwa kwemikhiqizo nokusebenza okungaguquki, ukuqina okuthuthukisiwe, nokusebenza okuthuthukisiwe.Ngesidingo esikhulayo sezinto ezisebenza kahle kakhulu, ukuthuthukiswa kwama-rheological thickeners amasha kulindeleke ukuthi kuqhubeke, kuqhutshwa intuthuko kwezesayensi yezinto zokwakha, amakhemikhali kanye nobunjiniyela.
