Kukula kwa cellulose ether

Cellulose ether amataya matope onyowa ndi mawonekedwe abwino kwambiri, omwe amatha kuwonjezera luso pakati pa matope ndi maziko a anti-sag matope a matope. Amagwiritsidwa ntchito kwambiri mu matope ojambula, khoma lakunja kapena njerwa zomangira matope. Mphamvu ya etherse ether ether imathanso kufooka kwa zinthu zodziwika bwino za mmenga, kupewa kuzengereza, kusankhana ndi magazi konkriti, ndipo kunkriti konkriti.

Cellulose Ether imawonjezera mapangidwe a zinthu zochokera ku mafayilo a cellulose eyather. Mndandanda wa "Masulidwe" nthawi zambiri amagwiritsidwa ntchito kuwunika mafayilo a eleulse eyather. Makutu a cellulose ether nthawi zambiri amatanthauza njira ya cellulose yomwe ili ndi ndende inayake (monga 2%). Kuthamanga (kapena kuchuluka kwa kuzungulira, monga 20 rpm), mtengo wa ma vistch umayesedwa ndi chida choyezera (monga chojambulidwa).

Ma Ukuwoneka ndi gawo lofunikira kuti muyesere magwiridwe antchito a cellulose. Kukula kwa ether eleulse yankho la exuluse, mafayilo obwera chifukwa cha zinthu zomwe zidapangidwa ndi simenti, zotsatsa zabwino za gawo lapansi, komanso zolimba komanso zonyansa ndi zonyansa. Ngati ma virus ake ndi okwera kwambiri, zimakhudza madzi ndi kuthekera kwa zinthu za simenti (monga kugwirira ntchito kumatayala komwe kumapakidwa mpeni mukamapanga matonge). Chifukwa chake, mawidwe a cellulose ether omwe amagwiritsidwa ntchito matope osakanikirana nthawi zambiri amakhala 15,000 ~ 60,000 MPA. S-1, matope okhaokha komanso konkriti wodziletsa, zomwe zimafuna kuti madzi ambiri amasungunuke, amafuna kuti mamasukidwe a cellulose.

Kuphatikiza apo, mphamvu ya kukula kwa cellulose Ether Ether imachulukitsa madzi a simenti, potero akuwonjezera zokolola za matope.

Makutu a eleul eleul soluse amadalira zinthu zotsatirazi:

Kulemera kwa maselo (kapena digiri ya polymerization) ndi kukhazikika kwa cellulose ether, njira yothetsera kutentha, mtengo wamaso ndi njira yoyesera.

1. Kukwera kwambiri kwa polymerization kwa cellulose ether, chitole chokulirapo, komanso kuchuluka kwa yankho lake;

2. Mlingo wapamwamba (kapena ndende) ya ethel ether, mawonekedwe owoneka bwino a yankho lake, koma chisamaliro chikuyenera kumwedwa kuti chisankhe gawo loyenera mukamagwiritsa ntchito matope ndi konkriti ngati mlingo wake ndi waukulu kwambiri;

3. Monga zakumwa zambiri, mafayilo a eleluse elefase amatha kuchepa ndi kuchuluka kwa kutentha, komanso kuchuluka kwa cellulose ether ether;

4. Treuluse ether solul nthawi zambiri imakhala preeudoplastic, yomwe ili ndi nyumba yowonda. Mlingo waukulu wa chimbudzi pakuyesa, kutsitsa ma visc.

Chifukwa chake, kuphatikiza kwa matope kudzachepetsedwa chifukwa cha mphamvu yakunja, yomwe imakhala yopindulitsa pakumanga matope a matope, kotero kuti matope atha kukhala ndi ntchito yabwino komanso yolumikizira nthawi yomweyo. Komabe, kusinthanitsa kwa exulse kolima kuwonetsa zamadzimadzi a Newtonia pomwe ndende itakhala yotsika kwambiri ndipo maonedwewo ndi ochepa. Pamene kupsanjika kumawonjezeka, yankho lakelo lidzawonetsa pang'onopang'ono madzimadzi amadzimadzi, ndi kuchuluka kwa chidwi, zodziwikiratu zomwe zikuchitika.
