Zomwe Zimayambitsa Ma cellulose Ether pa Simenti ya Simenti

Ma cellulose ethers amagwira ntchito yofunika kwambiri pakuwongolera mphamvu ya matope a simenti, kukhudza magwiridwe ake, kumamatira, kusunga madzi, komanso mphamvu zamakina. Zinthu zingapo zimatha kukhudza magwiridwe antchito a cellulose ethers mumatope a simenti:

1. Kapangidwe ka Chemical: Kapangidwe ka ma cellulose ethers, kuphatikiza kuchuluka kwa substitution (DS) ndi mtundu wamagulu ogwira ntchito (mwachitsanzo, methyl, ethyl, hydroxypropyl), zimakhudza kwambiri machitidwe awo mumatope a simenti. Ma DS apamwamba ndi mitundu ina yamagulu ogwira ntchito amatha kupititsa patsogolo kusungirako madzi, kumamatira, ndi kukhuthala.
2. Tinthu Kukula ndi Kugawa: The tinthu kukula ndi kugawa mapadi ethers zingakhudze awo dispersibility ndi mogwirizana ndi particles simenti. Tinthu tating'onoting'ono tomwe timagawanitsa yunifolomu timabalalika bwino m'matrix amatope, zomwe zimapangitsa kuti madzi asungidwe bwino komanso kuti azigwira ntchito bwino.
3. Mlingo: Mlingo wa ma cellulose ethers mu matope a simenti amakhudza momwe amagwirira ntchito. Mulingo woyenera kwambiri wa mlingo umatsimikiziridwa kutengera zinthu monga momwe angagwiritsire ntchito, zofunika kusunga madzi, ndi mphamvu zamakina. Kuchuluka kwa mlingo kungayambitse kukhuthala kwambiri kapena kuchepetsa nthawi yoikika.
4. Njira Yosakaniza: Njira yosakaniza, kuphatikizapo nthawi yosakaniza, kuthamanga kwa kusakaniza, ndi dongosolo la kuwonjezera kwa zosakaniza, zimatha kukhudza kubalalitsidwa ndi kutsekemera kwa ma cellulose ethers mumatope a simenti. Kusakaniza koyenera kumatsimikizira kugawidwa kofanana kwa ma cellulose ethers mumatope amatope, kumapangitsa kuti azitha kugwira bwino ntchito komanso kumamatira.
5. Mapangidwe a Simenti: Mtundu ndi mawonekedwe a simenti omwe amagwiritsidwa ntchito popanga matope amatha kusokoneza kuyanjana ndi magwiridwe antchito a cellulose ethers. Mitundu yosiyanasiyana ya simenti (mwachitsanzo, simenti ya Portland, simenti yosakanikirana) imatha kuwonetsa kuyanjana kosiyanasiyana ndi ma cellulose ether, zomwe zimakhudza monga kuyika nthawi, kukulitsa mphamvu, komanso kulimba.
6. Aggregate Properties: The katundu wa aggregates (mwachitsanzo, tinthu kukula, mawonekedwe, pamwamba kapangidwe) zingakhudze kagwiridwe ntchito ka cellulose ethers mu matope. Zophatikizika zokhala ndi zowoneka bwino kapena zosawoneka bwino zimatha kulumikiza bwino makina ndi ma cellulose ethers, kumawonjezera kumamatira ndi kulumikizana mumatope.
7. Mikhalidwe Yachilengedwe: Zinthu zachilengedwe monga kutentha, chinyezi, ndi machiritso zimatha kukhudza hydration ndi magwiridwe antchito a cellulose ethers mumatope a simenti. Kutentha kwambiri kapena chinyezi kungasinthe nthawi yoyika, kugwira ntchito, ndi makina amatope okhala ndi ma cellulose ethers.
8. Kuwonjezera Zina Zowonjezera: Kukhalapo kwa zowonjezera zina, monga superplasticizers, air-entraining agents, kapena seti accelerators, zimatha kugwirizana ndi ma cellulose ethers ndi kukhudza ntchito yawo mumatope a simenti. Kuyesa ngati kuli kogwirizana kuyenera kuchitidwa kuti awone zotsatira zofananira kapena zotsutsana ndi kuphatikiza ma cellulose ether ndi zowonjezera zina.

Kumvetsetsa zinthu zomwe zimathandizira ma cellulose ethers pamatope a simenti ndikofunikira kuti muzitha kukonza matope ndi kukwaniritsa zinthu zomwe mukufuna monga kugwirira ntchito bwino, kusunga madzi, komanso mphamvu zamakina. Kufufuza mozama ndi kuyesa kungathandize kuzindikira zinthu zoyenera kwambiri za cellulose ether ndi milingo ya mlingo wa ntchito zinazake zamatope.
