Njira zotsutsana ndi kugwiritsa ntchito ma ethyl cellulose

1. Njira yopumira ya ethyl cellulose
Ethyl cellulose (EC) ndi mankhwala opangidwa ndi cellulose yachilengedwe, yomwe ili ndi zinthu zabwino, zosawoneka bwino komanso zopanda pake. Chifukwa kapangidwe kake kamakhala ndi magulu ambiri a hydroxyl ndi a ethyl, amakhala ndi zovuta zina posungunuka. Pofuna kusungunula bwino cellulose, njira zingapo zosinthira ndipo nthawi zambiri zimafunikira.

Kusankhidwa
Kusungunuka kwa ethyl cellulose kumadalira kulemera kwake, kuchuluka kwa ethylation ndi zosungunulira. Chifukwa cha mawonekedwe a ethyl cellulose, nthawi zambiri imatha mphamvu m'madzi, koma imatha kusungunuka m'malo osiyanasiyana okhazikika. Zinyama zogwiritsidwa ntchito kwambiri ndizophatikiza:

Mankhwala omwa mowa: monga Ethanol, isoppanol, n-prosenol, etc., ethyl cellose yosonyeza kusasinthika kwabwino mu izi.
Ethernts ethernts: monga dimethyl muluxide (DMSO), chloroform, etc., imatha kupasulira ethy cellouse.
Ketolone solt: Monga acetone, etc., yoyenera kusungunuka kwa sing'anga molecular ethyl cellulose.
Ma sol sol sol: monga chloroform, kaboni Tetrachloride, etc., amathanso kugwiritsidwa ntchito ngati ma sol sol, koma chitetezo chiyenera kunyamula chidwi pakugwiritsa ntchito.

Masitepe Osiyanasiyana
Kusintha kwa zinthu kosasinthika kwa ethyl cellulose nthawi zambiri:
Kusungunuka: sinthani mosamala ethyl cellulose kwa osungunulira, onetsetsani kuti kuchuluka kwa zosungunulira ndikokwanira kuphimba cellose ya ethyl, ndikuyambitsa mwachidwi kuti ithandizire kufalikira mopitilira muyeso.
Kutenthetsa Kusungunuka: Ngati kuli kovuta kusungunuka firiji, kutentha kumatha kuwonjezeka bwino (nthawi zambiri osapitilira 70 ° C) ndikutenthetsedwa pansi pa ethyl cellulose kuti isungunuke.
Kuchepetsa: Pambuyo pa kufalikira kumamalizidwa, ngati pali thovu mu zosungunulira, thovu amatha kupulumutsidwa ndikukhazikitsa kukakamira kapena kukhazikika kwa yankho lomaliza.

Kusamala mukamawonongeka
Kulamulira kwa mayiko: Wokwera kwambiri cellose ndende imatha kuyambitsa vuto. Ndikulimbikitsidwa kusintha kususuka pakafunika kutero.
Kusankhidwa: Kusiyanasiyana kwa ethyl cellulose (monga zolemera zosiyana za maselo, madigiri osiyana siyana) ali ndi zofunikira zosiyanasiyana zoyeserera. Kusankha zosungunulira zoyenera kumathandiza kukonza zofananira.

2. Kugwiritsa ntchito ma ethyl cellulose
Cellose Cellose imagwiritsidwa ntchito kwambiri m'minda yambiri chifukwa cha njira yake yabwino kwambiri komanso yosinthira, yomwe imapanga filimu, kukhazikika, ndi zina. Nazi zina mwazomwe zimagwiritsidwa ntchito:

Oyendetsa mankhwala osokoneza bongo
Ethyl Cellose ali ndi zinthu zabwino komanso zoyambira, ndipo nthawi zambiri zimagwiritsidwa ntchito ngati mankhwala otulutsa mankhwala omasulira kapena omasulira. Zimatha kusintha mphamvu bwino ya mankhwala osokoneza bongo komanso kuchepetsa zovuta mwa kuwongolera kuthamanga ndi nthawi ya mankhwala. Ntchito Zodziwika Zimaphatikizapo kugwiritsa ntchito mankhwala osokoneza bongo, mankhwala omasulira, etc.

Zokutira ndi zisonyezo za membrane
Ethyl cellulose ili ndi katundu wabwino kwambiri wamakanema komanso mphamvu yamakina, motero imagwiritsidwa ntchito kwambiri mu chakudya ndi zokutira mankhwala. Itha kupanga kanema wocheperako komanso yunifolomu kuti muteteze zinthu zakunja kuchokera kumalo akunja ndikuwonjezera bata ndi alumali moyo wa malonda. Zojambula zodziwika bwino zimaphatikizapo zokutidwa ndi shuga, zokutira zamankhwala, etc.

Makampani Ogulitsa Chakudya
M'makampani azakudya, ethyl cellulose imagwiritsidwa ntchito kwambiri ngati chakudya chowonjezera. Itha kugwiritsidwa ntchito ngati thiccener, hithabili, elsilfier, etc. kukonza mawonekedwe ndi kukoma kwa chakudya. Mwachitsanzo, cellose Cellose itha kugwiritsidwa ntchito ngati cholowa m'malo mwa zakudya zotsika kwambiri kuti zithandizire kuwongolera zopezeka zamafuta ndi shuga.

Makampani opanga zodzikongoletsera
Mu cosmetics, ethyl cellulose nthawi zambiri imagwiritsidwa ntchito ngati thiclifer, emulsifier ndi filimu yomwe imatha kusintha, yomwe imatha kusintha kusasinthika, kukhazikika ndi kukhudza kwa emulsion mukamagwiritsa ntchito. Mwachitsanzo, cellose cellose imatha kupezeka pazopangidwa monga zokumana nazo zamafuta, zowongolera, ndi milomo.

Mapepala ndi kusanja
Monga kukhululuka kwa cellulose, ma cellose a ethyl amatenga gawo lofunikira pokonza mapepala ndi ziwalo. Itha kuwonjezera mphamvu ya pepala, sinthani mawonekedwe apamwamba, ndikusintha banga ndi kukana kwa ma utwala.

Zovala ndi zojambula
Monga kanema wakale zokumba, ethyl cellulose imagwiritsidwanso ntchito popanga utoto ndi zokutira. Zimatha kusintha kulimba mtima, kukhazikika komanso kutsatira zokutira, ngakhale kumawonjezera kukula kwa zokutira.

Zilengedwe Zachilengedwe
Chifukwa cha kuwonongeka kwake komanso zoopsa zochepa, ethyl cellulose yaphunziridwanso chifukwa cha chitukuko cha zinthu zachilengedwe. Mwachitsanzo, m'madzi amadzimadzi ndi kusintha kwa nthaka, kuteteza zachilengedwe kwa ethyl cellulose kumapangitsa kuti zikhale zobiriwira zambiri.

Monga chinthu chofunikira cha mankhwala, cellose cosluuse imatenga gawo lofunikira m'mafakitale ambiri. Njira yake yotsutsira imatengera kusankha kwa organic, ndipo ma sol sol wamba amaphatikiza mowa, ndi ma kemoni. Malinga ndi kugwiritsa ntchito mosiyanasiyana, cellulose ya ethyl imatha kugwiritsidwa ntchito kwambiri potulutsa mankhwala osokoneza bongo, makampani opanga zakudya, kupanga zodzikongoletsera komanso magawo ena, ndipo ali ndi mwayi wokhala ndi mwayi wokhala ndi chilengedwe. Ndi ntchito yowonjezereka ya zinthu zobiriwira komanso zachilengedwe zachilengedwe, chiyembekezo chogwiritsa ntchito cha ethyl cellose ndiyambiri.
