Kodi ndi zinthu ziti zomwe zimagwiritsidwa ntchito ndi ethyl cellulose?

Ethyl cellulose (ethyl cellulose ether), imadziwikanso kuti cellulose ether ether, imatchedwa EC.
Kapangidwe kake ka mawonekedwe ndi mawonekedwe a: [C6H7O2 (OC2h5) 3] N.
1.
Izi zimakhala ndi ntchito zogwirira ntchito, kudzaza, mawonekedwe a filimu, zowonjezera, zomata zam'manja, komanso zomata zamitundu yambiri, zomwe zimagwiritsidwa ntchito ngati magulu ankhondo.
2. Zofunikira
Malinga ndi kugwiritsa ntchito mosiyanasiyana, EC ya Commercise ikhoza kugawidwa m'magulu awiri: kalasi ya mafakitale ndi kalasi ya mankhwala, ndipo nthawi zambiri amasungunuka m'malo okhazikika. Kwa gawo la PEBRACUUTIC EC EC, muyezo wake wapamwamba uyenera kukwaniritsa miyezo ya Demacopoeia 2000 Edition (kapena USP PRACUCOMIA NDI RAPICOPOMIA ya Javine).
3.. Mankhwala akuthupi ndi mankhwala
1. Maonekedwe: EC ndi yoyera kapena yopepuka ya madzimadzi, fungo.
2. Katundu: EC ya Commercise nthawi zambiri imakhala yopanda madzi m'madzi, koma osungunuka m'malo osiyanasiyana oyipitsidwa. Ili ndi zolimba zamatenthedwe, phulusa kwambiri phulusa lotenthedwa, ndipo silimamamatira kapena kumva zowoneka bwino. Itha kupanga filimu yolimba. Imatha kupitilizabe kusinthasintha. Izi sizopanda kupweteka, zimakhala ndi zoletsa zachilengedwe, ndipo zimakonda kuwonongeka kwa oxiducation pansi pa dzuwa kapena kuwala kwa ultraviolet. Kuti mupeze EC ya chapadera, palinso mitundu yomwe imasungunuka mu LYE ndi madzi abwino. Kwa EC yokhala ndi digiri ya cholowa pamwamba 1.5, ndi thermoplastic, ndi malo osokoneza bongo a 135 ~ malo a pseudo ~ 107 ~ 1.18 g / cm3. Kuchuluka kwa chikondwerero cha EC kumakhudza kusungunuka, manyowa amadzi, makina opanga ndi mafuta. Pamene kuchuluka kwa chitukuko kumawonjezeka, kusungunuka ku Lye kumachepetsa, pomwe kusungunuka mosungunuka kwa ortic sodic kumawonjezeka. Solbles ambiri okhazikika. Zogwiritsidwa ntchito kwambiri zosungunulira ndi tolhanul / ethanol ngati 4/1 (kulemera) kusungunuka. Kuchuluka kwa chitukuko kumawonjezeka, malo ofewetsa ndi hygroscopicity amatsika, ndipo kutentha kwa ntchito ndi -60 ° C ~ 85 ° C. Kukhala mphamvu 13.7 ~ 54.9mka, odziwika voliyumu 10 * e12 ~ 10 * e14 ω14 ω.cm
Ethyl cellulose (DS: 2.3-2.6) ndi ma ether ether ether ethelose omwe amakhutira m'madzi koma sungunuka mu ma sol sol sol.
1.Ndi yosavuta kuwotcha.
2.good mafuta okhazikika komanso ma thermos abwino kwambiri.
3.Komwe sizisintha utoto ndi kuwala kwa dzuwa.
4. Kusinthasinthasintha.
5.Goud Seelectric.
6.Imakhala ndi kukana kwakukulu kwa alkali komanso kukana asidi acid.
7.good arting magwiridwe antchito.
8.Munthu Mchere Kutsutsana, Kulimbana Ndi Kuzizira Ndi Chinyezi Nthawi Zonse Kukana.
9.iti khola ku mankhwala ndipo siziwonongeka pakusungidwa kwa nthawi yayitali.

4. Njira Yokhumudwitsa
Zogwiritsidwa ntchito kwambiri zogwiritsidwa ntchito kwambiri kwa cellulose (DS: 2.3 ~ 2.6) ndi ma hydrocarbons ndi mowa. Aromatics akhoza kukhala benzene, Toline, Ethylbenzere, Xyylz, etc., yokhala ndi 60-80%; Mowa amatha kukhala methanol, ethanol, etc., ndi kuchuluka kwa 2040%. Pang'onopang'ono kuwonjezera etrander yomwe ili ndi zosungunulira pansi poyambitsa mpaka kunyozedwa kwathunthu ndikusungunuka.

5. Kugwiritsa Ntchito
Chifukwa cha kukhazikika kwa madzi, ethyl cellulose imagwiritsidwa ntchito ngati piritsi la piritsi ndi zokutira kanema, ndi zina zambiri.
Kugwiritsidwa ntchito ngati chinthu chosakanikirana chokonzekera kukonzekera kokhazikika ndi ma pellets omasulidwa;
Amagwiritsidwa ntchito ngati njira zothandizira mwazidziwitso zokhazikika pokonzekera mic malatopsules yotulutsidwa, kuti mankhwalawa atha kumasulidwa mosalekeza ndikuletsa mankhwala osungunuka osungunuka osungunuka osaphuka;
Itha kugwiritsidwanso ntchito ngati wobalalitsa, wosungunuka, komanso madzi omwe amasungidwa mitundu yosiyanasiyana ya mankhwala kuteteza chinyezi komanso kuwonongeka kwa mankhwala ndikusintha malo osungira mapiritsi.
