Kukhuthala ndi kusunga madzi kwa ethers a cellulose

Cellulose ether nthawi zambiri imakhala yofunika kwambiri mu mortars wouma. Chifukwa ndi chinthu chofunikira kwambiri chosungira madzi chomwe chili ndi mphamvu zabwino kwambiri zosungira madzi. Mphamvu imeneyi yosungira madzi imatha kuletsa madzi omwe ali mu mortars wonyowa kuti asatuluke msanga kapena kuyamwa ndi substrate, kutalikitsa nthawi yogwiritsira ntchito mortars wonyowa, kuonetsetsa kuti simenti ili ndi madzi okwanira, motero pamapeto pake imaonetsetsa kuti mortars ali ndi mphamvu, zomwe zimathandiza kwambiri popanga mortars woonda (monga mortars plastering) ndi mortars m'malo onyowa kwambiri (monga ma blocks a konkriti opumira), kutentha kwambiri komanso malo ouma.

Kapangidwe ka cellulose kosunga madzi kamagwirizana kwambiri ndi kukhuthala kwake. Kukhuthala kwa etha ya cellulose kukakwera, kumakhala bwino kwambiri pakusunga madzi. Kukhuthala ndi gawo lofunikira pakugwira ntchito kwa MC. Pakadali pano, opanga osiyanasiyana a MC amagwiritsa ntchito njira ndi zida zosiyanasiyana poyesa kukhuthala kwa MC, ndipo njira zazikulu ndi Haake Rotovisko, Hoppler, Ubbelohde ndi Brookfield. Pa chinthu chomwecho, zotsatira za kukhuthala zomwe zimayesedwa ndi njira zosiyanasiyana zimasiyana kwambiri, ndipo zina zimasiyana kwambiri. Chifukwa chake, poyerekeza kukhuthala, ndikofunikira kuchita izi pakati pa njira zoyesera zomwezo, kuphatikiza kutentha, rotor, ndi zina zotero.

Kawirikawiri, kukhuthala kwa madzi kukakhala kwakukulu, kumakhala bwino kwambiri. Komabe, kukhuthala kwa madzi kukakhala kwakukulu, kulemera kwa mamolekyulu a MC kumakhala kwakukulu komanso kuchepa kofanana kwa kusungunuka kwake, zomwe zimakhudza mphamvu ndi magwiridwe antchito a matope. Kukhuthala kwa madzi kukakhala kwakukulu, kukhuthala kwa matope kumakhala koonekera bwino. Kukhuthala kwa madzi kukakhala kwakukulu, kumamatira kwambiri matope onyowa, pomanga, monga momwe zasonyezedwera ndi chotsukira chomata komanso kumamatira kwambiri ku substrate. Komabe, sizithandiza kwambiri kuwonjezera mphamvu ya matope onyowa. Pomanga zonsezi, zimasonyeza kuti mphamvu yoletsa kugwa siikuonekera bwino. M'malo mwake, kukhuthala kochepa mpaka kwapakati koma ma ether a methyl cellulose osinthidwa ali ndi magwiridwe antchito abwino kwambiri pakukweza mphamvu ya matope onyowa.
