Isingeniso: I-HEC Iba Yisengezo Esibalulekile Esisebenzayo Ekunyathelisweni Kwezindwangu Zanamuhla

Imboni yokunyathelisa izindwangu iqhubeka nokuthuthuka iye ekuqondeni okuphezulu, ukusebenza kombala okungcono, kanye nezinqubo zokukhiqiza ezinakekela imvelo. Njengoba izinhlobo zemfashini kanye nabakhiqizi bezindwangu befuna amaphethini abukhali, ukuhambisana kombala okuthuthukisiwe, kanye nezinqubo zokunyathelisa ezisebenzayo, indima yezithasiselo ezisebenzayo ekufakweni kokunamathiswa kokunyathelisa isibe yinto ebaluleke kakhulu.

Phakathi kwezinto ezahlukahlukene zokuqinisa ezisetshenziswa ekunyatheliseni izindwangu,I-Hydroxyethyl Cellulose (HEC)idonsele ukunaka okukhulu ngenxa yokulawula kwayo okuhle kakhulu kwe-rheological, ikhono lokugcina amanzi, ukuhambisana nodayi kanye nemibala, kanye nezici ezinobungani nemvelo.

I-HEC iyi-ether ye-cellulose engeyona i-ionic etholakala ku-cellulose yemvelo ngokuguqulwa kwamakhemikhali. Ngenxa yesakhiwo sayo esiyingqayizivele sama-molecule, i-HEC ingalungisa ngempumelelo i-printing paste viscosity, ithuthukise ukuzinza kwesikrini, ivimbele ukopha kombala, futhi ithuthukise ukucaca kwamaphethini aphrintiwe.

Ezinhlelweni zokunyathelisa ngezindwangu, ikhwalithi ye-paste yokunyathelisa ithonya ngqo:

• Ukucija kwephethini
