Kodi ndi zinthu ziti zomwe zimakhudza kusungidwa kwamadzi kwa cellulose ether?

Ma cellulose ethers, monga methyl cellulose (MC) ndi hydroxyethyl cellulose (HEC), amagwiritsidwa ntchito ngati zosunga madzi m'zinthu zomangira monga matope opangidwa ndi simenti ndi ma pulasitala opangidwa ndi gypsum.Kusungidwa kwamadzi kwa cellulose ethers kumatha kutengera zinthu zosiyanasiyana:

1. Kapangidwe ka Chemical: Kapangidwe kake ka cellulose ethers kumakhudza momwe amasungira madzi.Mwachitsanzo, hydroxyethyl cellulose (HEC) nthawi zambiri imawonetsa kusungidwa kwamadzi kwambiri poyerekeza ndi methyl cellulose (MC) chifukwa cha kukhalapo kwa magulu a hydroxyethyl, omwe amathandizira kumanga madzi.
2. Kulemera kwa Mamolekyulu: Ma cellulose ethers apamwamba kwambiri amakhala ndi zinthu zabwino zosungira madzi chifukwa amapanga maukonde owonjezera a hydrogen ndi mamolekyu amadzi.Zotsatira zake, ma cellulose ether okhala ndi mamolekyu apamwamba kwambiri nthawi zambiri amasunga madzi bwino kuposa omwe ali ndi masikelo ochepera a mamolekyu.
3. Mlingo: Kuchuluka kwa etha ya cellulose yomwe imawonjezeredwa mumatope kapena pulasitala kumapangitsa kuti madzi asungidwe.Kuwonjezeka kwa mlingo wa cellulose ether kumapangitsa kuti madzi asungidwe, mpaka pamene kuwonjezereka kwina sikungawongolere kusungirako ndipo kungawononge zinthu zina zakuthupi.
4. Tinthu Kukula ndi Kugawa: The tinthu kukula ndi kugawa mapadi ethers angakhudze awo dispersibility ndi mphamvu kusunga madzi.Finely pansi mapadi etha ndi yunifolomu tinthu kukula kugawa amakonda kumwazikana kwambiri wogawana mu osakaniza, zikubweretsa bwino posungira madzi.
5. Kutentha ndi Chinyezi: Mikhalidwe ya chilengedwe, monga kutentha ndi chinyezi, ingakhudze hydration ndi kusunga madzi a cellulose ethers.Kutentha kwapamwamba kumatha kufulumizitsa ndondomeko ya hydration, zomwe zimapangitsa kuti madzi ayambe kuyamwa mofulumira komanso kuchepetsa kusungirako madzi.Mosiyana ndi zimenezi, kutsika kwa chinyezi kungapangitse kuti madzi asamawonongeke komanso kuchepetsa kusunga madzi.
6. Mtundu wa Simenti ndi Zowonjezera: Mtundu wa simenti ndi zowonjezera zina zomwe zimapezeka mumatope kapena pulasitala osakaniza zimatha kuyanjana ndi ma cellulose ethers ndikuwongolera momwe amasungira madzi.Mitundu ina ya simenti kapena zowonjezera zimatha kukulitsa kapena kuletsa kusungidwa kwamadzi kutengera kuyanjana kwawo ndi mankhwala komanso kuyanjana ndi ma cellulose ethers.
7. Njira Yosakaniza: Njira yosakaniza, kuphatikizapo nthawi yosakaniza, kusakaniza liwiro, ndi dongosolo la kuwonjezera zosakaniza, zingakhudze kubalalitsidwa ndi hydration ya cellulose ethers mu osakaniza.Kusakaniza koyenera ndikofunikira kuti zitsimikizire kugawa kofanana kwa ma cellulose ethers ndikuwonjezera kusunga madzi.
8. Kuchiritsa Mikhalidwe: Machiritso, monga kuchiritsa nthawi ndi kutentha, amatha kukhudza hydration ndi kusunga madzi kwa cellulose ethers muzinthu zochiritsidwa.Kuchiza kokwanira ndikofunikira kuti ma cellulose ethers azikhala ndi madzi okwanira komanso kuthandizira kusunga madzi kwanthawi yayitali muzinthu zowuma.

Poganizira izi, akatswiri omanga amatha kukhathamiritsa kugwiritsa ntchito ma cellulose ethers ngati zosunga madzi mumatope ndi pulasitala kuti akwaniritse magwiridwe antchito monga kugwirira ntchito, kumamatira, komanso kulimba.
