Zithini iipropathi kunye nokusetyenziswa kwe-sethyl sethyl?

I-Ethyl Selelose (Ethyy Selese I-Ether), ekwabizwa ngokuba yi-Teluplose Ether, ekubhekiswa kuyo i-EC.
Ifomula yemolekyuli kunye nendlela yolwakhiwo: [c6h7o2 (OC2h5) 3] n.
1.Umntu
Le mveliso inemisebenzi ye-bonding, yokugcwalisa, ukwenziwa kwefilimu, njl njl.
2. Iimfuneko zobugcisa
Ngokutsho kokusetyenziswa okwahlukeneyo, i-EC ethengiswayo inokwahlulwa yangamacandelo amabini: Ibakala lezishishini kunye nenqanaba lamachiza, kwaye anyibilikiswa rhoqo kwiinyibilikisi. Ibanga laseMelika, umgangatho wayo osemgangathweni kufuneka uhlangabezane nemigangatho ye-Chinese Pharmacopoeia 2000 i-Edition (okanye i-USP XX19 i-Edition kunye ne-pharmacopoopoeia ye-pharmacoopoeia i-pharmacoeia i-pharmapoeia i-JP.
I-3. Iipropathi zomzimba kunye neekhemikhali
1. Imbonakalo: I-EC i-mhlophe okanye i-fleid emhlophe emhlophe, ngaphandle kwe-odor.
2. Iipropathi: I-EC ye-EC i-EC ngokubanzi ingena emanzini, kodwa inyibilikisiwe kwizinyibilikisi ezahlukeneyo. Inozinzo oluhle lobushushu, umxholo ophantsi kakhulu xa watshiswa, kwaye unqabile ukuba uzincamathi okanye uziva ngathi unomdla. Inokwenza ifilimu enzima. Ingagcina ukuba bhetyebhetye. Le mveliso ayinatyhefu, inepropathi eyomeleleyo yebhayoloji, kwaye i-Intebort ye-Inteboost, kodwa inomdla wokupheliswa kwe-oxindive phantsi kwelanga okanye ukukhanya kwe-ultraviolet. Nge-EC-injongo ye-EC, kukwakhona iintlobo ezinyibilikisayo kwi-LYE kunye namanzi acocekileyo. I-EC enenqanaba lokufakelwa ngaphezulu kwe-1.5, yi-thermoplastic, kunye nendawo enomxholo we-135 ~ 155 ° 25 ° 2 ° 2, i-pseudo i-0.3 ~ 4,18 g / cm3. Inqanaba lokuthengiswa kwe-EC ichaphazela ukuzola, ukufunxa kwamanzi, iipropathi zoomatshini kunye neepropathi ze-thermal. Njengamanqanaba e-etherhesition anyukayo, ukunyibilisela kwi-LYE kuyancipha, ngelixa isolula kwizicolo eziphilayo ziyanda. Inyibilikisiwe kwizinyibilikisi ezininzi. I-Solvent esetyenzisiweyo yi-scolvent yi-toluene / etshanol njenge-4 / (ubunzima) yenyibilikisiwe. Inqanaba lokuthengiswa kwe-ether, indawo yokuthambisa kunye nokuhlela i-hygroscoficity yehla, kunye neqondo lokushisa elisetyenziswayo ngu-60 ° C ~ 85 ° C. Amandla amanxuwa 13.7 ~ 54.9MPA, ukuntywila kwe-10 * E12 ~ E14 ω.cm
I-Ethyl Selelose (DS: 2.3-2.6) Ngaba i-ionic ye-ionic seseli enganyibilikiyo emanzini kodwa inyibilikisiwe kwiinyibilikisi zendalo.

11.T kulula ukutshintsha umbala phantsi kwendawo ye-alkaline yomeleleyo kunye nobushushu.
4. Indlela yokuphelisa
Ezona ziqhelekileyo zisetyenziswayo zisetyenziswayo ze-Simesyl sethyl secelose (DS: 2.3 ~ 2.6) zii-hydrocarbles ezinhlakeleyo. I-aromatics inokuba ngu-Benzene, i-toulene, i-sylbenzene, i-xylene, njlnjl. I-alcohols inokuba yiMetanol, ethanol, njl njl, ngexabiso lama-20 ukuya kwi-40%. Kancinci ukongeza i-EC kwisitya esine-solvent sithambekele de itshiswe ngokupheleleyo kwaye ichithwe.

5. Isicelo
Ngenxa yokungothuki kwamanzi, i-sethyl sethyl sethyl isetyenziswa ikakhulu njenge-Binder yeTafile kunye neZinto zokuDibanisa iFilimu, njl.
Isetyenziswe njengento exubeneyo yokulungiselela amalungiselelo okukhutshwa okuzinzileyo kunye neepelethi ezikhutshelweyo;
Isetyenziswa njenge-accopuble into encedisayo ukulungiselela i-microcaps ebilayo, ukuze isiphumo seziyobisi sinokukhululwa ngokuqhubekayo kwaye sikhusele iziyobisi ezinyibilikayo ezivela ngaphambi kwexesha;
Ingasetyenziselwa ukusasazeka, i-stabilizer, kunye nearhente yokugcina amanzi kwiifom ezahlukeneyo zethamo zokuthintela ukufuma kunye nokuthintela amayeza kunye nokuphucula ukugcinwa okukhuselekileyo kweetafile.
