1.Ku
Ichi chigadzirwa chine mabasa ekubatanidza, kuchizadza, firimu kuumbwa, etcings substitiki plastics, etc.
2. Zvinetso zvehunyanzvi
Zvinoenderana nekushandisa kwakasiyana, kushambadzira EC inogona kukamurwa kuita zvikamu zviviri: Maindasitiri giredhi uye giredhi giredhi, uye anowanzo nyora mu organic sol sol. Kune pharmaceutical grade EC, iyo mhando yemhando yayo inofanirwa kusangana nezviyero zveChinese phmacoeia
3. Zvepanyama uye zvemakemikari zvivakwa
1. Kutaridzika: EC chena kana chena grey fluid poda, kusanzwisisika.
2. Iyo ine yakanaka yekunyora yekugadzikana, yakanyanya kuderera yezvikamu kana yakapiswa, uye kashoma kuti inomuka kana inonzwa kushamwaridzana. Inogona kuumba firimu rakaoma. Iyo inogona kuramba ichiramba ichishanduka. Ichi chigadzirwa hachina chepfu, chine simba rakasimba renyama, uye rinoenderana nestorti, asi inowanzoita oxidative degridation pasi pezuva kana ultravioler mwenje. Nezve Special-Chinangwa EC, kune zvakare mimwe mimwe mitezo inovanyungudika mumvura nemvura yakachena. Nekuti EC pamwe nedanho rekutsiva kumusoro 1.5, iri thermoplastic, neyekunyorova kwe135 ~ ° C.3 ~ Dhigirii rekutsamwa kweEC inokanganisa solubility, mvura yemvura, manhamba emhando uye zvigadzirwa zvekupisa. Sezvo degree rekutsvaira rinowedzera, iyo solubility muLyode inoderera, nepo iyo solubility mu organic sol soles inowedzera. Nyura mune akawanda organic sol sol. Kazhinji inoshandiswa solvent ndeye tluene / ethanol se4/1 (uremu) yakasanganiswa sol. Dhigirii rekutsvaira rinowedzera, iyo inonamira poindi uye hygroscopicity inoderera, uye tembiricha yekushandisa ndeye -60 ° C ~ 85 ° C. Tensile Simba 13.7 ~ 54.9mpa, vhoriyamu Rudzidziso 10 * E12 ~ 10 * 14 ω.cm
EtHyl Cellulose (DS: DS: 2.3-2.6) is is is is-ionic cellelose ether is inonetseka mumvura asi yakachena mu organic sol sol.
1.not nyore kupisa.

8.Good munyu kuramba, kutonhora kuramba uye kunyorova kupokana kuramba.
9. yakagadzikana pamakemikari uye haizoregi mukuchengetedza kwenguva refu.
10.Inogona kuwirirana nevakawanda majona uye vane kuwirirana kwakanaka neese mapapu.
11.Iiri nyore kuchinja ruvara pasi peakasimba alkaline nharaunda uye kupisa.
4. Dissolution nzira
Iyo inonyanya kushandiswa yakasanganiswa sol sol sold Aromatics inogona kuve benzene, toluene, ethylbenene, xylene, nezvimwe, nehuwandu hwe60-80%; Accleohols anogona kuve methanol, ethanol, nezvimwewo, nehuwandu hwe20-40%. Zvishoma nezvishoma wedzera ec kumudziyo une solvent pasi pekumuka kusvikira yanyoroveswa uye yakanyungudutswa.

5. Chikumbiro
Nekuda kwe insoluby yemvura yayo, mainterlose anonyanya kushandiswa sedhipatimendi rehasha uye nemafirimu ekubatanidza zvinhu, et.
Inoshandiswa sechinhu chakasanganiswa kugadzirira yakagadziriswa yekugadzirira-gadziriro gadziriro uye yakasimudzwa-inosunungura pellets;
Izvo zvinoshandiswa sechinhu chekuwedzera zvinhu zvekushandisa zvinogadzira microcaps
Inogona zvakare kushandiswa seinoparadzira, uye siminizer, uye yekuchengetedza mvura mumufomu akasiyana-siyana mishonga yekudzivirira uye kuora kwemishonga uye kugadzirisa kuchengetedza kwematafura.
