I-Hydroxyethyl cellulose (HEC) iyinhlanganisela ebalulekile ye-polymer encibilika emanzini engeyona i-ionic enezinhlobonhlobo zezicelo embonini kapende neyokumboza.
1. Ukuqina
I-Hydroxyethyl cellulose iyi-thickener esebenza kahle kakhulu. Ingakwazi ukwandisa i-viscosity kapende ngokumunca amanzi esixazululweni se-aqueous ukuze sandise futhi senze isisombululo se-colloidal. Lokhu akusizi nje kuphela ukuvimbela upende ukuthi ungahlali ngesikhathi sokugcina nokuthutha, kodwa futhi kuthuthukisa izakhiwo zayo zokumisa nokumiswa, ukuqinisekisa ukufana nokushelela kwengubo yopende.
2. Ukulawulwa kwe-Rheological
I-Hydroxyethyl cellulose ingakwazi ukulungisa izakhiwo ze-rheological zopende, okungukuthi, ukushintsha izici zayo zokugeleza ngamanani ahlukene we-shear. Ingakwazi ukugcina upende ku-viscosity ethile esimweni esimile ukuvimbela ukugoqa; futhi phakathi nenqubo yokufaka isicelo, i-viscosity izokwehla ngokunyuka kwezinga le-shear, elilungele ukwakhiwa. Le ndawo isiza ukuthuthukisa ukwakhiwa nokusebenza kahle kopende.
3. Ukugcinwa kwamanzi
I-Hydroxyethyl cellulose inokugcinwa kwamanzi okuhle kakhulu. Ingakwazi ukuvimbela ngempumelelo ukuhwamuka kwamanzi ngokushesha okukhulu, ngaleyo ndlela yandise isikhathi sokumisa upende futhi ivumele ifilimu kapende ukuba ibe nesikhathi esanele sokulinganisa kanye nokwakheka kwefilimu phakathi nenqubo yokomisa. Lokhu kubaluleke kakhulu kumapende asekelwe emanzini, njengoba ukulahlekelwa kwamanzi ngokushesha kungabangela izinkinga ezifana nezimbobo nokuqhekeka kwefilimu yepende.
4. Ukuzinza kanye nezakhiwo eziphikisana nokuxazulula
Ekwakheni upende, ikakhulukazi amasistimu aqukethe i-pigment eqinile kanye nama-filler, i-hydroxyethyl cellulose inganikeza ukuzinza okuhle kokumiswa ngokuqina. Ingakwazi ukuvimbela ngokuphumelelayo ukucwiliswa kwama-pigments nama-fillers, iqinisekise ukubunjwa okufanayo kopende ngesikhathi sokugcina, futhi ngaleyo ndlela iqinisekise ukuhambisana kombala nokuzinza kokusebenza kwe-coating.
5. Thuthukisa izici zokwenza ifilimu
I-Hydroxyethyl cellulose ingathuthukisa izakhiwo zefilimu zopende. Ingenza isendlalelo sefilimu efanayo ebusweni bokugqoka, sithuthukise i-gloss kanye nokufana kwefilimu yepende. Ngaphezu kwalokho, i-hydroxyethyl cellulose ingabuye ithuthukise ukumelana ne-powdering kanye nokuphikiswa kwamanzi kwefilimu yokugqoka, ikhulise ukuqina kwayo kanye nezakhiwo zokuhlobisa.
6. Izakhiwo ezihambisana nemvelo
Njenge-thickener engeyona i-ionic, i-hydroxyethyl cellulose ayinazo izinsimbi ezisindayo nezincibilikisi eziyingozi, futhi ihlangabezana nezidingo zokuvikela imvelo. Ukusetshenziswa kwawo kumapende asekelwe emanzini kunganciphisa okuqukethwe kwe-volatile organic compounds (VOCs), esiza ukunciphisa ukungcoliswa kwemvelo kanye nokulimala empilweni yomuntu.
Ukusetshenziswa kwe-hydroxyethyl cellulose kupende akuthuthukisi nje kuphela izakhiwo ezingokomzimba nokusebenza kokwakhiwa komkhiqizo, kodwa futhi kuhlangabezana nezidingo zokuvikela imvelo kanye nokuphepha kwemboni yezingubo zanamuhla. Njengesengezo esisebenza ngezinto eziningi, sidlala indima ebalulekile ekwakhiweni kwesakhiwo kanye nenqubo yokufaka upende.
