I-Ethyl Cellulose- EC umphakeli

I-Ethyl cellulose iyi-polymer engancibiliki emanzini etholakala ku-cellulose, i-biopolymer yemvelo etholakala ezindongeni zamaseli ezitshalo. Isetshenziswa kakhulu ezimbonini ezahlukahlukene, kufaka phakathi ezemithi, ukudla, nokunakekelwa komuntu siqu, ngenxa yezakhiwo zayo eziyingqayizivele, okuhlanganisa ukuncibilika, ikhono lokwenza ifilimu, kanye nobuthi obuphansi. Lesi sihloko sizodingida izakhiwo, ukwakheka, kanye nokusetshenziswa kwe-ethyl cellulose.

Properties of Ethyl Cellulose I-Ethyl cellulose iyimpahla ye-thermoplastic encibilika kuzincibilikisi zemvelo, njenge-ethanol, kodwa ayincibiliki emanzini. Ukunyibilika kwe-ethyl cellulose kungalungiswa ngokushintsha izinga layo lokushintsha, okubhekisela enanini lamaqembu e-ethyl ngeyunithi ngayinye ye-glucose ku-molecule ye-cellulose. I-Ethyl cellulose enezinga eliphakeme lokushintshwa incibilika kakhulu kuzincibilikisi zemvelo, kuyilapho lezo ezinezinga eliphansi lokushintshwa zincibilika kancane.

I-Ethyl cellulose yaziwa ngekhono layo elihle kakhulu lokwenza ifilimu futhi ingasetshenziswa ukwenza ifilimu efanayo futhi ezinzile. Izakhiwo zefilimu ze-ethyl cellulose zingathuthukiswa ngokuqhubekayo ngokungeza ama-plasticizers, njenge-dibutyl phthalate noma i-triacetin, okwandisa ukuguquguquka nokunwebeka kwefilimu. Amafilimu e-Ethyl cellulose avame ukusetshenziswa embonini yezemithi njengezingubo zokugqoka amaphilisi, amaphilisi, nama-granules.

Ukwenziwa kwe-Ethyl Cellulose I-Ethyl cellulose ihlanganiswa ngokuphendula i-cellulose ne-ethyl chloride phambi kwesisekelo, njenge-sodium hydroxide noma i-potassium hydroxide. Ukusabela kuhilela ukufakwa esikhundleni kwamaqembu e-hydroxyl ku-molecule ye-cellulose namaqembu e-ethyl, okuholela ekwakhekeni kwe-ethyl cellulose. Izinga lokushintsha lingalawulwa ngokulungisa izimo zokusabela, njengokugxila kwama-reactants kanye nesikhathi sokusabela.

Izicelo ze-Ethyl Cellulose Pharmaceuticals: I-Ethyl cellulose isetshenziswa kakhulu embonini yezemithi ngenxa yekhono layo elihle kakhulu lokwenza ifilimu kanye nobuthi obuphansi. Isetshenziswa njengezinto zokumboza amaphilisi, amaphilisi, kanye nama-granules, okuthuthukisa ukuzinza kwawo futhi kuvimbele ukuthi angahlakazeki emgudwini wamathumbu. Izembatho ze-Ethyl cellulose nazo zingasetshenziswa ukulawula ukukhululwa kwezidakamizwa ngokushintsha izinga lokuchithwa kwazo.

Ukudla: I-Ethyl cellulose isetshenziswa njengesengezo sokudla ukuze kuthuthukiswe ukuthungwa nokuzinza kokudla. Ivamise ukusetshenziswa njenge-thickener, binder, kanye ne-stabilizer ekudleni okugayiwe, njengamasoso, okokugqoka, nezinto ezibhakwayo. I-Ethyl cellulose ingasetshenziswa futhi njengesimbozo sezithelo nemifino ukuze kwandiswe isikhathi sazo seshalofu futhi kuvimbele ukubola.

Ukunakekelwa Komuntu Siqu: I-Ethyl cellulose isetshenziswa emikhiqizweni ehlukahlukene yokunakekela abantu, njengezimonyo, ama-shampoos, nama-lotions, ngenxa yekhono layo lokwenza ifilimu kanye nezindawo ezimelana namanzi. Ivamise ukusetshenziswa njenge-thickener kanye ne-stabilizer ezimonyoni futhi ingasetshenziswa futhi njenge-ejenti eyenza ifilimu kuzifutho zezinwele kanye nemikhiqizo yesitayela.

Ezinye Izinto Ezisetshenziswayo: I-Ethyl cellulose isetshenziswa kwezinye izinto ezihlukahlukene, njengoyinki, ama-coatings, izinto zokunamathisela, nopende. Ivame ukusetshenziswa njenge-binder kuma-coatings nanjenge-thickener kumayinki. I-Ethyl cellulose ingasetshenziswa futhi njengento evimbela amanzi ephepheni nanjengesibopho sezinto zobumba.

Kafushane, i-ethyl cellulose iyi-polymer engancibiliki emanzini etholakala ku-cellulose esetshenziswa kabanzi ezimbonini ezahlukahlukene, kufaka phakathi ezemithi, ukudla, nokunakekelwa komuntu siqu. Iyaziwa ngekhono layo elihle kakhulu lokwenza ifilimu, ubuthi obuphansi, kanye nezindawo ezikwazi ukumelana namanzi, okuyenza ifanelekele ukusetshenziswa okuhlukahlukene.
