Kukhuthala kwa ma cellulose ethers

Ma cellulose ethers amapereka mamasukidwe abwino kwambiri kumatope onyowa, amawonjezera kwambiri kuthekera kolumikizana kwamatope onyowa ku gawo lapansi ndikuwongolera kukana kwamatope, ndipo amagwiritsidwa ntchito kwambiri popaka matope, matope omangira njerwa ndi machitidwe otchinjiriza akunja. The thickening zotsatira za mapadi ether akhoza kuonjezera odana dispersing mphamvu ndi homogeneity wa zipangizo mwatsopano osakaniza, kupewa delamination zakuthupi, tsankho ndi madzi katulutsidwe, ndipo angagwiritsidwe ntchito CHIKWANGWANI konkire, pansi pa madzi konkire ndi kudzipangira compacting konkire.

Kuchuluka kwa ma cellulose ethers pa zinthu za simenti kumabwera chifukwa cha kukhuthala kwa mulu wa cellulose ether. Pazifukwa zomwezo, kuwonjezereka kwa kukhuthala kwa cellulose ether, kumapangitsanso kukhuthala kwa zinthu zosinthidwa cementitious, koma ngati mamasukidwe akayendedwe ndi okwera kwambiri, zingakhudze fluidity ndi workability wa zinthu (mwachitsanzo mipeni yomata pulasitala). Mitondo yodzipangira yokha ndi konkriti yodzipangira yokha, yomwe imafunikira madzi ambiri, imafunikira kukhuthala kochepa kwa ma cellulose ethers. Kuphatikiza apo, kukhuthala kwa ma cellulose ethers kumawonjezera kufunikira kwa madzi pazinthu za simenti ndikuwonjezera zokolola zamatope.

The mamasukidwe akayendedwe a mapadi etero njira zimadalira zinthu zotsatirazi: maselo kulemera kwa mapadi ether, ndende, kutentha, kukameta ubweya mlingo ndi mayeso njira. Pazifukwa zomwezo, kulemera kwakukulu kwa maselo a cellulose ether, kumapangitsanso kukhuthala kwa yankho; apamwamba ndende, ndi apamwamba mamasukidwe akayendedwe a yankho, mu ntchito chidwi ayenera kulipidwa kupewa kwambiri dosing ndi zimakhudza ntchito zimatha matope ndi konkire; cellulose ether solution viscosity idzachepa ndi kuwonjezeka kwa kutentha, ndipo kumtunda kwa ndende, kumapangitsanso kutentha; Ma cellulose ether solution nthawi zambiri amakhala pseudoplastic fluid, ndi chikhalidwe cha kumeta ubweya wa ubweya, kuyesedwa kwakukulu Kuchuluka kwa kukameta ubweya wa mayeso, kung'onozing'ono kwa mamasukidwe aang'ono, kotero kugwirizana kwa matope kudzachepetsedwa pansi pa mphamvu zakunja, zomwe zimathandiza kuti matope apangidwe, kotero kuti matope akhoza kukhala ndi nthawi yabwino yogwira ntchito; chifukwa yankho la cellulose ether ndi madzimadzi osakhala a Newtonian, njira zoyesera za viscosity test, zida kapena malo oyesera, zotsatira za mayeso a cellulose ether zitha kukhala zosiyana kwambiri.
