Uphuhliso lweRheological Thickener

Uphuhliso lwe-rheological thickeners ibe yimbali ebalulekileyo kwimbali yezinto zesayensi kunye nobunjineli. I-Rheological thickeners zizinto ezinokonyusa i-viscosity kunye / okanye ukulawula ukuhamba kweempawu zolwelo, ukumiswa, kunye ne-emulsions.

I-rheological thickener yokuqala yafunyanwa ngengozi ngenkulungwane ye-19, xa umxube wamanzi kunye nomgubo ushiywe ukuba ume ixesha elithile, ubangele into eninzi, efana nejeli. Lo mxube kamva wafunyaniswa ukuba kukunqunyanyiswa okulula kwamasuntswana omgubo emanzini, anokusetyenziswa njengento yokutyebisa kwizicelo ezahlukeneyo.

Ebutsheni benkulungwane yama-20, kwafunyaniswa ukuba ezinye izinto zazityeba, njengestatshi, iintsini nodongwe. Ezi zixhobo zazisetyenziswa njenge-rheological thickeners kuluhlu lwezicelo, ukusuka ekutyeni nakwizinto zokuthambisa ukuya kwiipeyinti kunye nolwelo lokomba.

Nangona kunjalo, ezi zingqimba zendalo zinemida, ezifana nokusebenza okuguquguqukayo, ubuntununtunu kwiimeko zokusetyenzwa, kunye nokungcoliseka kwe-microbiological. Oku kukhokelele kuphuhliso lwezingqimba zerheological zokwenziwa, ezifana ne-cellulose ethers, iipolima ze-acrylic, kunye ne-polyurethanes.

I-cellulose ethers, njenge-sodium carboxymethyl cellulose (CMC), i-methyl cellulose (MC), kunye ne-hydroxypropyl cellulose (HPC), ibe yenye yezona zinto zisetyenziswa kakhulu kwi-rheological thickeners kwizicelo ezahlukeneyo, ngenxa yeempawu zabo ezizodwa, ezifana nokunyibilika kwamanzi, Uzinzo lwe-pH, amandla e-ionic amandla, kunye nokukwazi ukwenza ifilimu.

Uphuhliso lwe-rheological thickeners eyenziwe yavumela ukuqulunqwa kweemveliso kunye nokusebenza okufanayo, ukuphucula ukuzinza, kunye nokusebenza okuphuculweyo. Ngemfuno ekhulayo yezixhobo zokusebenza eziphezulu, uphuhliso lwe-rheological thickeners entsha kulindeleke ukuba luqhubeke, luqhutywa yinkqubela phambili kwisayensi yezinto, ikhemistri, kunye nobunjineli.
