I-Ethylcellulose iyi-polymer eguquguqukayo esetshenziswa ezimbonini ezahlukahlukene, kufaka phakathi ezemithi, okokuhlanganisa, okokunamathelisa kanye nokudla. Amabanga ahlukene e-ethylcellulose enziwa ngokwezifiso ukuze ahlangabezane nezidingo ezithile ngokuya nge-viscosity, isisindo samangqamuzana nezinye izakhiwo.
Isakhiwo se-Ethyl cellulose:
I-Ethylcellulose iphuma ku-cellulose, i-polymer yemvelo etholakala ezindongeni zamaseli ezitshalo. I-Ethylation ye-cellulose ihilela ukwethulwa kwamaqembu e-ethyl ekusebenzeni kwe-hydroxyl (-OH) ye-cellulose. Lokhu kuguqulwa kunikeza i-ethylcellulose izakhiwo eziyingqayizivele, iyenze inyibilike kuzinyibilikisi zemvelo futhi inikeze amakhono amahle kakhulu okwenza ifilimu.
Izimpawu ze-ethylcellulose:
I-Solubility: I-Ethylcellulose inyibilika ezinhlobonhlobo zezincibilikisi eziphilayo, njengotshwala, ama-ketone, ama-ester, njll.
Izakhiwo zokwakha ifilimu: Izakhiwo ezinhle kakhulu zokwakha ifilimu, ezifanele ukumbozwa namafilimu.
I-Thermoplasticity: I-Ethylcellulose ibonisa ukuziphatha kwe-thermoplastic, ukuyivumela ukuthi ibunjwe noma yakheke lapho ishiswa.
I-inert: I-inert yamakhemikhali, ihlinzeka ngokuzinza kuzinhlelo zokusebenza ezihlukahlukene.
Izinhlobo ze-Ethylcellulose:
1. Ibanga le-viscosity eliphansi:
Lawa mabanga anesisindo esiphansi samangqamuzana ngakho-ke i-viscosity ephansi.
Ilungele izinhlelo zokusebenza ezidinga i-coatings emincane noma amafilimu.
Izibonelo zifaka ukwakheka kwemithi ekhishwa okulawulwayo kanye nama-coatings azacile kumathebulethi.
2. Ibanga le-viscosity elimaphakathi:
Isisindo samangqamuzana amaphakathi kanye ne-viscosity.
Isetshenziswa kakhulu embonini yezemithi ekwakhiweni kokukhishwa okuqhubekayo, lapho ibhalansi phakathi kogqinsi bokunamathela nezinga lokukhishwa libalulekile.
Ibuye isetshenziswe ekukhiqizeni okukhethekile okunamathelayo nama-sealants.
3. Ibanga le-viscosity ephezulu:
Lawa mabanga anesisindo samangqamuzana aphezulu ngakho-ke ama-viscosity aphezulu.
Ilungele izinhlelo zokusebenza ezidinga ama-coatings aminyene noma amafilimu.
Isetshenziselwa ukukhiqizwa kwezingubo zokuzivikela ezifana noyinki, amapende nama-varnish.
4. Izinga elihle kakhulu:
Lawa mabanga anosayizi bezinhlayiyana ezincane, okusiza ukwenza ukunamathela kube bushelelezi futhi kuthuthukise ukuhlakazeka ezixazululweni.
Thola izinhlelo zokusebenza zoyinki wokuphrinta wekhwalithi ephezulu nama-coatings wokulungiselela izindawo ezinhle.
5. Amabanga aphezulu wokuqukethwe kwe-ethoxy:
I-Ethylcellulose enezinga eliphezulu le-ethoxylation.
Ihlinzeka nge-solubility ethuthukisiwe kuhlu olubanzi lwezincibilikisi.
Isetshenziswa ezinhlelweni ezidinga ama-polymers ancibilika kakhulu, afana nokwakheka okuthile kwemithi.
6. Izinga lomswakama ophansi:
I-Ethyl cellulose enomswakama oncishisiwe.
Ilungele ukusetshenziswa lapho ukuzwela komswakama kuwukukhathazeka, njengokukhiqizwa kwemithi engezwani namanzi.
7. Amabanga eThermoplastic:
Lawa mabanga abonisa ukuziphatha okuthuthukisiwe kwe-thermoplastic.
Isetshenziswa ekubumbeni lapho izinto zidinga ukuthanjiswa futhi zibunjwe emazingeni okushisa aphezulu.
8. Izinga lokukhishwa elilawulwayo:
Idizayinelwe ukwakheka kwemithi edinga ukukhishwa kwezidakamizwa okulawulwayo esikhathini eside.
Iklanyelwe ukufeza ama-kinetics okukhululwa ngenkathi igcina ukuzinza.
Ukusetshenziswa kwe-ethylcellulose:
1. Izidakamizwa:
Ukukhishwa okulawulwayo amalungiselelo emithi.
Izembatho zethebhulethi zokufihla ukunambitheka nokuqedwa okulawulwayo.
I-binder yama-granules ekwenziweni kwethebhulethi.
2. Izigqoko noyinki:
Ukumbozwa kokuzivikela kwezindawo ezihlukahlukene.
Ukuphrinta oyinki bokuphrinta kwe-flexographic kanye ne-gravure.
Izingubo zezimoto nezimboni.
3. Izinamathiselo nama-sealants:
Okunamathelayo okukhethekile kwezinhlelo zokusebenza ezihlukahlukene.
Ama-sealants asetshenziselwa amalunga kanye nokuvala ekwakhiweni nasekukhiqizeni.
4. Imboni yokudla:
Izingubo ezidliwayo zezithelo nemifino zandisa impilo yeshalofu.
Ukufakwa kwe-flavour nama-perfume.
5. Ipulasitiki kanye Nokubunjwa:
Ukuziphatha kwe-Thermoplastic ekubumbeni izinhlelo zokusebenza.
Ikhiqiza imikhiqizo yepulasitiki ekhethekile.
6. Imikhiqizo kagesi:
Isetshenziselwa ukukhiqizwa kwezingubo zokuzivikela zezingxenye ze-elekthronikhi.
Ekuphetheni:
Amamaki ahlukahlukene e-ethylcellulose ayatholakala ukuze ahlangabezane nezinhlobonhlobo zezicelo ezimbonini ezahlukahlukene. Kusukela kwezemithi kuye kwezinamatshe nezinamathelisa, ukuguquguquka kwe-ethylcellulose kusesigabeni sayo esihlukene, ngalinye liklanyelwe ukuhlangabezana nezidingo ezithile. Njengoba izidingo zobuchwepheshe nezimboni ziqhubeka nokuvela, ukuthuthukiswa kwamabanga amasha e-ethylcellulose anezakhiwo ezithuthukisiwe kungase kudlale indima ebalulekile ekuhlangabezaneni nezidingo zezicelo ezivelayo. Ukuqonda umehluko phakathi kwala mabanga kwenza abakhiqizi bakwazi ukukhetha i-ethylcellulose efaneleke kakhulu yohlelo lwabo oluthile, okuqinisekisa ukusebenza kahle nokusebenza kahle.
