Ukusetshenziswa kwe-PVA fiber kukhonkolo

Abstract:

Amafayibha e-Polyvinyl alcohol (PVA) avele njengesengezo esithembisayo kubuchwepheshe obuphathekayo, esiza ukuthuthukisa izakhiwo ezihlukahlukene zemishini nokuqina. Lokhu kubuyekezwa okuphelele kuhlola imiphumela yokufaka imicu ye-PVA ezixubeni zikakhonkolo, kuxoxiswane ngezakhiwo zazo, izinqubo zokukhiqiza, kanye nezinhlelo zokusebenza ezahlukahlukene embonini yezokwakha. Ingxoxo ihlanganisa imiphumela yamafayibha e-PVA ezintweni ezintsha neziqinile zikakhonkolo, indima yazo ekuvimbeleni ukuqhekeka, kanye nezinzuzo ezingaba khona zemvelo ezihlobene nokusetshenziswa kwazo. Ukwengeza, izinselele namathemba esikhathi esizayo ayagqanyiswa ukuze kuqondiswe olunye ucwaningo nentuthuko kulo mkhakha.
