Ukuziphatha kwesigaba kanye nokwakheka kwe-fibril ku-aquouse cellulose afer

Ukuziphatha kwesigaba kanye nokwakheka kwe-fibril ku-aquodI-Cellulose Afersyimicimbi eyinkimbinkimbi ethonywe isakhiwo samakhemikhali se-cellulose afers, ukugxila kwabo, izinga lokushisa kanye nokuba khona kwezinye izengezo. I-Cellulose Tashers, efana ne-hydroxypropyll methylcellulose (HPMC) kanye ne-carboxymethyl cellulose (CMC), zaziwa ngekhono lazo lefomu futhi zibonisa izinguquko zesigaba esijabulisayo. Nakhu ukubuka konke okujwayelekile:

Isigaba Ukuziphatha:

1. Inguquko ye-Sol-Gel:
   • Izisombululo ezinamanzi ze-cellulose tifers zivame ukuguqulwa inguquko ye-sol-gel njengoba ukuncipha kwenyuka.
   • Lapho kugxila okuphansi, ikhambi liziphatha njenge-liquid (sol), ngenkathi ligxile kakhulu, lakha isakhiwo esinjenge-gel.
2. Ukuhlushwa okubucayi kwe-gelation (CGC):
   • I-CGC iyinhlangano yokuhlanza lapho kwenzeka khona isixazululo sejeli.
   • Izici ezithonya i-CGC zifaka izinga lokufakwa esikhundleni se-cellulose ether, izinga lokushisa kanye nokuba khona kosawoti noma ezinye izengezo.
3. Ukuncika kokushisa:
   • I-gelation imvamisa incike emazingeni okushisa, ngokubonisa ezinye izipho ze-cellulose ekhombisa ukukhuphuka kwe-gelisation emazingeni okushisa aphezulu.
   • Lokhu kuzwakala kokushisa kusetshenziswa kuzinhlelo zokusebenza njengokukhishwa kwezidakamizwa okulawulwayo kanye nokusebenza kokudla.

Ukwakheka kwe-Fibril:

1. I-micellar aggregation:
   • Ngokugxila okuthile, ama-cellulose afers angakha ama-micelles noma ama-aggregates ngesixazululo.
   • Ukuhlanganiswa kuqhutshwa ukusebenzisana kwe-hydrophobic kwamaqembu e-ALKYL noma ama-Hydroxyalkyl angeniswa ngesikhathi sokuthezeka.
2. Fibrillogenesis:
   • Ukushintshwa kusuka kumaketanga we-soluble polymer kuya ku-insoluble Fibrils kufaka inqubo eyaziwa ngokuthi yi-fibrillogenesis.
   • Ama-Fibrils akhiwa ngokusebenzisana kwe-intermolecular, ukubopha ama-hydrogen, kanye nokufakwa ngokomzimba kwamaketanga we-polymer.
3. Ithonya lika-Shear:
   • Ukusetshenziswa kwamandla we-shear, njengokuvusa noma ukuxuba, kungakhuthaza ukwakheka kwe-fibril eCellulose Ether Solutions.
   • Izakhiwo ezibangelwe ze-Shear zihambelana nezinqubo zezimboni kanye nezicelo.
4. Izithasiselo kanye nokuwela:
   • Ukungezwa kosawoti noma ezinye izengezo kungathonya ukwakheka kwezinhlaka ze-fibrillar.
   • Ama-ejenti wokuwela angasetshenziselwa ukuzinza nokuqinisa ama-fibrils.

Izicelo:

1. Ukulethwa kwezidakamizwa:
   • I-gelation kanye nezakhiwo zokwakhiwa kwe-fibril ze-cellulose izithathekiswa zisetshenziswa ekuhlinzekweni kwezidakamizwa ezilawulwayo.
2. Imboni yokudla:
   • I-Cellulose Tashers inikela ngokuthungwa kanye nokuqina kwemikhiqizo yokudla nge-gelation nokuqina.
3. Imikhiqizo Yokunakekelwa Kwakho:
   • I-gelation kanye ne-fibril yokwakheka kuthuthukisa ukusebenza kwemikhiqizo efana nama-shampoos, ama-lotion, kanye nokhilimu.
4. Izinto zokwakha:
   • Izakhiwo ze-gelation zibalulekile ekuthuthukisweni kwezinto zokwakha ezinjengezinamathiseli ze-tile kanye nodaka.

Ukuqonda Ukuziphatha kwesigaba kanye nokwakhiwa kwe-fibril kwe-cellulose afers kubalulekile ukuze kuguqulwe kabusha izici zabo zohlelo oluthile. Abaphenyi namaqembu abasebenza ukwenza ngcono lezi zindawo zokusebenza okuthuthukile ezimbonini ezahlukahlukene.
