I-Ethyl Cellulose(EC)
Incazelo Yomkhiqizo
I-Ethyl Cellulose (EC) iyimpuphu enganambitheki, egeleza ngokukhululekile, emhlophe ukuya kokukhanya okunombala onsundu.ethyl cellulose ihlanganisa, ifilimu yangaphambili, futhi ijiya. Isetshenziswa kuma-suntan gels, ama-creams, nama-lotions. Lena i-ethyl ether ye-cellulose.I-Ethyl Cellulose EC iyancibilika ezinhlobonhlobo zezincibilikisi eziphilayo. Ngokuvamile, i-Ethyl Cellulose EC isetshenziswa njengengxenye engadumbeki, engancibiliki kumatrix noma ezinhlelweni zokumboza.
I-Ethyl Cellulose EC ingasetshenziswa ukumboza isithako esisodwa noma eziningi ezisebenzayo zethebhulethi ukuyivimbela ukuthi isabele kwezinye izinto noma enye kwenye. Ingavimbela ukuguquguquka kombala kwezinto ezitholakala kalula i-oxidizable njenge-ascorbic acid, ivumele ama-granulation amaphilisi acindezelwe kalula namanye amafomu omthamo.EC ingasetshenziswa yodwa noma ihlanganiswe nezingxenye ezincibilika emanzini ukuze kulungiswe ukumbozwa kwefilimu okuqhubekayo okuvame ukusetshenziselwa ukumbozwa kwezinhlayiya ezincane, amaphilisi namaphilisi.
I-Ethyl cellulose ayikwazi ukuncibilika emanzini, kodwa incibilika kuzincibilikisi eziningi eziphilayo, ngakho i-EC isetshenziswa kumaphilisi, ama-granules we-adhesive agent yayo. Kungakhuphula ubulukhuni bamaphilisi ukunciphisa amaphilisi e-friability, angasetshenziswa njenge-ejenti eyenza ifilimu ukuthuthukisa ukubukeka kwamaphilisi, ukunambitheka okuhlukile, ukugwema ukwehluleka kwezidakamizwa ezizwela amanzi ukuvimbela ukuthutheleka kwama-metamorphic change agents, ukukhuthaza. ukugcinwa okuphephile kwamaphilisi, nakho kungasetshenziswa njengokuqinisa amaphilisi okukhululwa okuqhubekayo.

Izinhlelo zokusebenza
I-Ethyl Cellulose iyi-resin enemisebenzi eminingi. Isebenza njenge-binder, thickener, rheology modifier, ifilimu yangaphambili, kanye nesithiyo samanzi ezinhlelweni eziningi njengoba kuchazwe ngezansi:
Izinamathiselo: I-Ethyl Cellulose isetshenziswa kabanzi ekuncibilikeni okushisayo nakwezinye izinto ezinamathelayo ezisuselwa kuncibiliki ngenxa ye-thermoplasticity yayo enhle kakhulu namandla aluhlaza. Incibilika kuma-polymer ashisayo, kumapulasitiki, namafutha.
Izembatho: I-Ethyl Cellulose ihlinzeka ngokuvimbela amanzi, ukuqina, ukuguquguquka nokucwebezela okuphezulu kumapende nezingubo. Ingase futhi isetshenziswe kwezinye izigqoko ezikhethekile ezifana nephepha lokuxhumana lokudla, izibani ze-fluorescent, uphahla, ama-enameling, ama-lacquers, ama-varnish, nama-marine coatings.
I-Ceramics: I-Ethyl Cellulose isetshenziswa kakhulu kuzitsha zobumba ezenzelwe izinhlelo zokusebenza ze-elekthronikhi njengama-multi-layer ceramic capacitor. Isebenza njenge-binder kanye ne-rheology modifier. Iphinde inikeze amandla aluhlaza futhi ishise ngaphandle kwezinsalela.
Oyinki Wokuphrinta: I-Ethyl Cellulose isetshenziswa ezinhlelweni zikayinki ezisekelwe ku-solvent njenge-gravure, i-flexographic noyinki wokuphrinta isikrini. I-organosoluble futhi ihambisana kakhulu nama-plasticizers nama-polymers. Ihlinzeka nge-rheology ethuthukisiwe kanye nezakhiwo ezibophayo esiza ukwakheka kwamandla aphezulu kanye namafilimu okumelana.
