Kukula kwa cellulose ether

Cellulose etherMaofesi Oseketsa Matope ndi Maonekedwe Abwino, amatha kuwonjezera luso la matope onyowa, kusintha matope a matope, njira zakunja ndi njerwa zopindika. Kusintha kwa kukula kwa ethel ether kumawonjezeranso luso la simenti ndi kutsutsa kwa simenti yatsopano ya simenti yatsopano, kuteteza matope ndi kutuluka kwa matope, konkriti pompopompo.

Cellulose etherKuchulukitsa mafayilo a zinthu zochokera ku mafayilo a cellulose eyather. Nthawi zambiri gwiritsani ntchito "mavictoni" kuti apange kusintha kwa magazi, mamasukidwe a cellulose ether (2%) ndi gawo la 20 rpm Mawonekedwe a ma viru ndi gawo lofunikira pakuyendetsa ma cellulose ndi ether ether, mafayilo a sitemer athe, koma ngati kapangidwe ka amphamvu kwambiri (monga kapangidwe ka pulayala matope omata). Chifukwa chake, mawidwe a cellulose ether omwe amagwiritsidwa ntchito matope osakanikirana nthawi zambiri amakhala 15,000 ~ 60,000 MPA. S-1, ndikuwoneka bwino kwa ethel ether imafunikira kuti ikhale yotsika matope okhaokha ndikudzipangira zodzitchinjiriza ndi madzi ambiri. Kuphatikiza apo, kusintha kwa kukula kwa cellulose ether kumawonjezera madzi ofunikira, potero ndikutulutsa matope. Makutu a eleul eleul socy amatengera kulemera kwa ma polymer (kapena digiri ya polymerization) ndi kukhazikika kwa ethel ether, njira yothetsera kutentha, ndi njira yoyeserera, komanso njira yoyesera. Ma digiri ya polymerization ya ethel ether, olemera olemera, mafayilo ake am'madzi; Mlingo wapamwamba (kapena ndende) ya ethel ether, ma viniyo ake ankhosa ake am'madzi, koma osagwiritsa ntchito kutcheratu kaseweredwe koyenera, kotero kuti asakanikize pasankhidwe woyenera, kuti asakanikize kwambiri matope ndi konkriti; Monga zakumwa zambiri, mafayilo a eleluse eleeluse amatha kuchepa ndi kuchuluka kwa kutentha, komanso kuchuluka kwa ma cellulose ether ether, ndiye kutentha kwakukulu; Ma cellulose ether solul nthawi zambiri amakhala ndi thupi la pseudoplastic ndi katundu wa shear. Mlingo wapamwamba, wotsika ma visc.

Chifukwa chake, kuphatikizapo matope adzachepetsedwa ndi mphamvu yakunja, yomwe imapangitsa kuti ntchito yomanga yomanga ya matope ikhale yolimbitsa thupi, yomwe imapangitsa kuti matope atha kukhala ogwira mtima komanso a coutheon. Komabe, kusinthana kwa cellulose kuwonetsa mawonekedwe a Newtonian Madzi a Newtonian pomwe ndende itakhala yotsika kwambiri ndipo mafalowo ndi ochepa kwambiri. Pamene kukhazikikako kumawonjezeka pang'onopang'ono, yankho lakelo limapereka madzimadzi amadzimadzi, komanso kuchuluka kwa chidwi, zodziwikiratu.
