I-Ethyl Cellulose(EC)
Ingcaciso yeMveliso
I-Ethyl Cellulose (EC) ayinancasa, ibaleka simahla, imhlophe ukuya kokukhanya kwe-tan-colored powder.ethyl cellulose yi-binder, ifilimu yangaphambili, kunye ne-thickener. Isetyenziswa kwijeli yelanga, iikhrimu, kunye nezinto zokuthambisa. Le yi-ethyl ether ye-cellulose.I-Ethyl Cellulose EC i-soluble kuluhlu olubanzi lwe-solvents eziphilayo. Ngokuqhelekileyo, i-Ethyl Cellulose EC isetyenziswe njengento engabonakaliyo, i-insolble component kwi-matrix okanye i-coating systems.
I-Ethyl Cellulose EC ingasetyenziselwa ukugquma isithako esinye okanye ezingaphezulu ezisebenzayo zethebhulethi ukuthintela ukusabela kwezinye izinto okanye enye kwenye. Inokuthintela ukuguquka kombala wezinto ezixutywe lula ezifana ne-ascorbic acid, evumela i-granulations kwiipilisi ezixinzelelekileyo kunye nezinye iifom zedosi. Ukwaleka kwee-micro-particles, iipellets kunye neepilisi.
I-Ethyl cellulose ayikwazi ukunyibilika emanzini, kodwa i-soluble kwi-solvents ezininzi zezinto eziphilayo, ngoko ke i-EC isetyenziswa kwiipilisi, iigranules ze-adhesive agent. Inokwandisa ubulukhuni beepilisi zokunciphisa iipilisi zokunciphisa i-friability, inokusetyenziswa njenge-agent-forming agent yokuphucula ukubonakala kwamacwecwe, incasa ezimeleyo, ukuphepha ukusilela kwamachiza athintela amanzi ukuthintela ukungena kwe-metamorphic change agents, ukukhuthaza. Ukugcinwa okukhuselekileyo kweetafile, nako kungasetyenziswa njengesixhobo sokuqinisa iipilisi ezikhutshwa ngokuqhubekayo.

Usetyenziso
I-Ethyl Cellulose i-resin enemisebenzi emininzi. Isebenza njengesibophelelo, i-thickener, i-rheology modifier, ifilimu yangaphambili, kunye nesithintelo samanzi kwizicelo ezininzi njengoko kuchaziwe ngezantsi:
I-Adhesives: I-Ethyl Cellulose isetyenziswa ngokubanzi kwiinyibiliko ezishushu kunye nezinye izincamathelisi ezisekelwe kwi-solvent ngenxa ye-thermoplasticity egqwesileyo kunye namandla aluhlaza. Iyanyibilika kwiipolymers ezishushu, iiplasticizers, kunye neoyile.
Iingubo: I-Ethyl Cellulose ibonelela ngokuthintela amanzi, ukuqina, ukuguquguquka kunye negloss ephezulu kwiipende kunye neengubo. Isenokusetyenziswa kwezinye izinto zokugquma ezikhethekileyo ezifana nephepha lokudibanisa ukutya, izibane zefluorescent, uphahla, i-enameling, i-lacquers, ivanishi, kunye neengubo zaselwandle.
I-Ceramics: I-Ethyl Cellulose isetyenziswa kakhulu kwi-ceramics eyenzelwe ukusetyenziswa kwe-elektroniki njenge-multi-layer ceramic capacitors. Isebenza njenge-binder kunye ne-rheology modifier. Ikwabonelela ngamandla aluhlaza kwaye itshisa ngaphandle kokushiya.
Ii-Inks zokuprinta: I-Ethyl Cellulose isetyenziselwa kwiinkqubo ze-inki ezisekelwe kwi-solvent ezifana ne-gravure, i-flexographic kunye neenki zokushicilela isikrini. I-organosoluble kwaye iyahambelana kakhulu neeplastiki kunye neepolymers. Ibonelela nge-rheology ephuculweyo kunye neempawu zokubopha ezinceda ukubunjwa kwamandla aphezulu kunye neefilimu ezichasayo.
