Kuchulukitsa 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 luso ndi homogeneity wa zipangizo mwatsopano osakaniza, kupewa delamination zakuthupi, tsankho ndi katulutsidwe madzi, 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 apamwamba 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 etere njira zimadalira zinthu zotsatirazi: maselo kulemera kwa mapadi etere, 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 kwakukulu;cellulose ether solution kawirikawiri ndi pseudoplastic fluid, ndi chikhalidwe cha kumeta ubweya wa ubweya, kuyesa kwakukulu Kuchuluka kwa kumeta ubweya wa mayeso, kung'onozing'ono kwa viscosity, kotero kuti mgwirizano wa matope udzachepetsedwa pansi pa mphamvu zakunja, zomwe zimathandiza kuti matope apangidwe, kotero kuti matope akhoza kukhala ndi ntchito yabwino ndi kugwirizana panthawi yomweyo;chifukwa njira ya cellulose ether ndi madzimadzi omwe si a Newtonian, njira zoyesera za viscosity test, zida kapena malo oyesera, zotsatira za mayeso a cellulose ether zitha kukhala zosiyana kwambiri.
