IHydroxyethyl Cellulose (HEC) iyisengezo esisetshenziswa kakhulu embonini kapende, eyaziwa ngamandla aso okuthuthukisa ukusebenza nokuguquguquka kokwakheka okuhlukahlukene kopende.Ngezakhiwo zayo eziyingqayizivele, i-HEC idlala indima ebalulekile ekuthuthukiseni ikhwalithi, ukusebenza nokuqina kwemikhiqizo kapende.
I-HEC iyi-polymer encibilika emanzini etholakala ku-cellulose, isakhi semvelo esitholakala ezitshalweni.Isakhiwo sayo samakhemikhali siqukethe amaqembu e-hydroxyl kanye ne-ethyl, afaka isandla ezintweni zawo eziyingqayizivele njengesengezo sikapende.I-HEC isebenza njenge-thickener, i-rheological modifier, i-stabilizer, ne-binder, iyenze ibe isithako esibalulekile ekwakhiweni kopende.
Enye yezinzuzo ezibalulekile ze-HEC kupende umphumela wayo wokujiya.Ngokungeza i-HEC, abakhiqizi bangakwazi ukulawula i-viscosity nokuvumelana kopende, baqinisekise ukuthi bushelelezi futhi bafaka isicelo ezindaweni ezihlukahlukene.Lo mphumela wokujiya usiza ekuvimbeleni ukuwohloka noma ukuconsa ngesikhathi sokufaka isicelo, okuholela ekuqedeni okulinganayo nobungcweti.
I-HEC iphinde isebenze njenge-rheological modifier, ethinta ukugeleza kanye nezakhiwo ezithambile zopende.Ithuthukisa ikhono likapende lokusakazeka ngokulinganayo, inciphise izimpawu zebhulashi noma zerola, futhi ithuthukise ukukhanga kobuhle bendawo ependiwe. Ngaphezu kwalokho, i-HEC isiza ukuvimbela ukuminza kwe-pigment, iqinisekisa ukuthi umbala uhlala usabalaliswe ngokulinganayo kulo lonke upende.
Ukwengeza, i-HEC ithuthukisa ukuzinza kokwakheka kopende. Ivimbela ukuhlukaniswa kwesigaba futhi igcina ubuqotho bopende ngokuhamba kwesikhathi, ngisho nasezimeni zokugcina eziyinselele.Lokhu kuzinza kuqinisekisa ukuthi upende ugcina izakhiwo ezifiselekayo kanye nokusebenza kuyo yonke impilo yayo yeshalofu.
Ngaphezu kwalokho, i-HEC isebenza njenge-binder, ithuthukisa ukunamathela kopende kuma-substrates ahlukahlukene. upende uhlala unamathele ngokuqinile phezulu, ngisho nalapho ubhekene nezimo zemvelo ezinzima.
Ukuhlukahluka kwe-HEC kudlulela ngalé kwendima yayo kupende wendabuko osuselwe kuncibilikisiwe.Iphinde ihambisane nokwakheka kwamanzi okusekelwe emanzini kanye ne-low-VOC (i-volatile organic compound), okuyenza ibe ukukhetha okuvumela imvelo ekusetshenzisweni kopende kwesimanje.I-HEC inika amandla ukukhiqizwa kopende bekhwalithi ephezulu, abaqaphela imvelo abahlangabezana nezidingo eziqinile zokulawula.
Sengiphetha, i-Hydroxyethyl Cellulose (HEC) iyisengezo esibalulekile embonini kapende, enikela ekusebenzeni okuthuthukisiwe, ukuguquguquka, kanye nokuhambisana kwemvelo kokwakheka kopende.Ukuqina kwayo, ukuguqulwa kwe-rheological, ukuthuthukisa ukuzinza kanye nezakhiwo ezibophayo kuyenza ibe isithako esibaluleke kakhulu kubakhiqizi abahlose ukukhiqiza opende bezinga eliphezulu abanezakhiwo ezihlukile.
Ukuze uthole ulwazi olwengeziwe nge-Hydroxyethyl Cellulose (HEC) kanye nokusetshenziswa kwayo embonini yokupenda, thintana ne-[Yiang cellulose], umhlinzeki oholayo wezixazululo ezisekelwe ku-cellulose nobuchule e- [China Jinzhou]
