Ethylcellulose nukuri ifata cyane mu nganda zinyuranye, cyane cyane mu miti, imiti, ibiryo, amavuta yo kwisiga.
Intangiriro kuri Ethyl selulose
Ethylcellulose ni inkomoko ya selile, polymer karemano iboneka murukuta rw'ibimera. Ikorwa na Ethylation reaction ya selile hamwe na Ethyl chloride cyangwa okiside ya Ethylene. Ihinduka ritanga ibikoresho byihariye, bituma bikwiranye na progaramu zitandukanye, cyane cyane nk'ibiti mu nganda zitandukanye.
Ibiranga Ethylcellulose
Imiterere yimiti: Ethylcellulose igizwe no gusubiramo ibice bya anhydroglucose ihujwe na β (1 → 4) glycosidic. Ethylation ya selile isimbuza amatsinda amwe ya hydroxyl (-OH) hamwe nitsinda rya ethoxy (-OCH2CH3).
Gukemura: Ethylcellulose ntishobora gushonga mumazi, ariko irashobora gushonga mumashanyarazi nka Ethanol, acetone, toluene, na chloroform. Uyu mutungo utuma uboneka mubisabwa bisaba kurwanya amazi.
Ubushobozi bwo gukora firime: Ethyl selulose irashobora gukora firime yoroheje kandi ibonerana nyuma yo gushonga mumashanyarazi akwiye. Izi firime zifite imbaraga zumukanishi hamwe na barrière.
Thermoplastique: Ethylcellulose yerekana imyitwarire ya thermoplastique, bigatuma byoroha gutunganya ukoresheje tekinike nko gukuramo, gutera inshinge, no guhonyora.
Guhuza: Ethylcellulose ihujwe nizindi polymers zitandukanye, plasitike hamwe ninyongeramusaruro, bigatuma ikoreshwa muburyo butandukanye.
Gukoresha Ethyl selulose nkibifatika
Inganda zimiti
Mu miti ya farumasi, Ethylcellulose ikora nkumuhuza mugukora ibinini. Ifasha guhuza ibikoresho bikora bya farumasi (API) hamwe nibisohoka hamwe, byemeza uburinganire bwibinini hamwe nuburinganire. Byongeye kandi, Ethylcellulose ikoreshwa no muburyo bugenzurwa-busaba ibiyobyabwenge bikomeza.
Inganda zibiribwa
Ethylcellulose ikoreshwa nkibihuza, kubyimbye, hamwe na stabilisateur mubiribwa. Ikoreshwa mugutwikira imbuto, imboga n'ibiryo bya kondereri kugirango ube mwiza kandi ubeho neza. Ipitingi ya Ethylcellulose itanga inzitizi irinda ubushuhe, imyuka n'ibihumanya.
3. Impuzu hamwe na wino
Mu nganda zo gutwika hamwe na wino, Ethylcellulose ikoreshwa nkububiko bwo gusiga amarangi, amarangi, amarangi, hamwe no gucapa wino. Iha iyi myenda ifatanye, ihinduka kandi ikarwanya amazi, bityo igateza imbere imikorere yayo nigihe kirekire.
4. Amavuta yo kwisiga
Ethylcellulose ikoreshwa nkibyimbye kandi bigahindura amavuta yo kwisiga nka cream, amavuta yo kwisiga hamwe nibicuruzwa byita kumisatsi. Ifasha kugera kubintu byifuzwa, guhuzagurika no kwiyegeranya muburyo bwo kwisiga.
5. Gusaba inganda
Mu nganda zikoreshwa mu nganda, Ethylcellulose ikoreshwa nkumuhuza mugukora ibikoresho byubutaka, abrasives na compte. Ifasha gukora imibiri yicyatsi no kugenzura imiterere ya rheologiya ya paste na slurries.
Synthesis ya Ethylcellulose
Synthesis ya Ethylcellulose ikubiyemo reaction ya selile hamwe na Ethylating agent mugihe cyagenwe. Imyitwarire ya Ethylation isanzwe ikorwa imbere ya catalizator nka acide cyangwa base kugirango iteze imbere gusimbuza amatsinda ya hydroxyl hamwe nitsinda rya ethoxy. Urwego rwo gusimbuza (DS) rwerekana impuzandengo ya matsinda ya ethoxy kuri glucose igice cyumurongo wa polymer kandi irashobora kugenzurwa no guhindura ibipimo byerekana nkibisubizo byigihe, ubushyuhe, nigipimo cyimyuka ya reaction.
Ibyiza bya Ethylcellulose nkumuhuza
Guhinduranya: Ethylcellulose yerekana ibintu byinshi mubijyanye no gukemuka, guhuza hamwe nubushobozi bwo gukora firime, bigatuma bikwiranye nibikorwa byinshi mubikorwa byinganda.
Kurwanya Amazi: Ethylcellulose ntishobora gushonga mumazi, bigatuma ihitamo neza kubisaba bisaba kurwanya amazi, nk'imyenda, amarangi, hamwe na farumasi irekura.
Thermoplastique: Imyitwarire ya thermoplastique ya Ethylcellulose ituma itunganywa byoroshye ukoresheje tekinoroji ya thermoplastique, itanga uburyo bwo gukora buhendutse.
Biocompatibilité: Ethylcellulose isanzwe izwi nk’umutekano (GRAS) n’inzego zishinzwe kugenzura imikoreshereze y’ibiribwa n’imiti, byemeza ibinyabuzima ndetse n’umutekano w’abaguzi.
Kurekurwa kugenzurwa: Ethylcellulose ikoreshwa cyane munganda zimiti kugirango ikore dosiye igenzurwa-irekura kugirango igenzure neza igipimo cy’ibiyobyabwenge.
Ethylcellulose ikora nkibihuza byinshi hamwe nibisabwa bitandukanye mubuvuzi, imiti, ibifuniko, amavuta yo kwisiga hamwe ninganda. Imiterere yihariye, harimo gukemuka, ubushobozi bwo gukora firime no guhuza, bituma iba ikintu cyingirakamaro muburyo butandukanye. Synthesis ya Ethylcellulose igerwaho na Ethylating selulose mugihe cyagenzuwe, bikavamo ibikoresho bifite imiterere yihariye ikwiranye nibisabwa byihariye. Hamwe no kurwanya amazi, thermoplastique no kurekurwa kugenzurwa, Ethylcellulose ikomeje kugira uruhare runini mukuzamura imikorere nimikorere yibicuruzwa mu nganda zitandukanye.
