Ama-cellulose ethers ayizithasiselo ezisetshenziswa kakhulu odakeni lwe-gypsum ukuthuthukisa izakhiwo zabo. I-Gypsum mortar iyingxube eyomile esetshenziswa kabanzi embonini yezokwakha ngezinhlelo zokusebenza ezihlukahlukene, njengokugcwalisa izikhala namajoyinti, ukulungisa imifantu ezindongeni nophahla, nokudala ukubunjwa kokuhlobisa. Ukwengeza ama-cellulose ether ku-gypsum mortar kungathuthukisa ukusebenza kwawo, ukugcinwa kwamanzi, ukubeka isikhathi namandla.
1. Thuthukisa ukusebenza
Enye yezinzuzo eziyinhloko zokusebenzisa ama-cellulose ethers ku-gypsum mortar ukuthi kuthuthukisa ukusebenza kwengxube. Ukusebenziseka kubhekisela ekukhululekeni kwezinto ezingaxutshwa, zithuthwe, futhi zifakwe phezulu. Ngokusebenzisa ama-cellulose ether, i-gypsum mortar iba uketshezi oluthe xaxa futhi kulula ukusakazeka, ngaleyo ndlela inciphise inani lomsebenzi odingekayo ekuxubeni nasekusetshenzisweni. Lokhu kubaluleke kakhulu kumaphrojekthi amakhulu wokwakha lapho isikhathi siwumongo futhi isivinini sohlelo lokusebenza sithinta ukukhiqiza.
2. Thuthukisa ukugcinwa kwamanzi
Enye inzuzo yokusebenzisa i-cellulose ethers ku-gypsum mortar ukuthi ithuthukisa ukugcinwa kwamanzi engxube. Lokhu kubalulekile ngoba i-gypsum mortar ijwayele ukoma ngokushesha, ikakhulukazi ezimweni ezomile nezishisayo. Ngokusebenzisa ama-cellulose ethers, ukugcinwa kwamanzi kwengxube kuyanda, okusho ukuthi udaka luhlala lunomswakama isikhathi eside, okwenza kube lula ukusebenza nalo futhi luvimbele ukuthi lungaqhekeki noma luqhekeke ngaphambi kwesikhathi. Lesi sici siwusizo ezindaweni ezinomswakama omncane noma lapho udaka kudingeka lufakwe khona endaweni eqondile lapho amandla adonsela phansi angabangela ingxube ukuthi ishelele.
3. Lawula isikhathi coagulation
I-Cellulose ether iphinde yengezwe ku-gypsum mortar ukulawula isikhathi sayo sokusetha. Isikhathi sokusetha yisikhathi esithathayo ukuze udaka lwe-gypsum olumanzi luguquke lube yisimo esiqinile. Lesi sikhathi sibalulekile kunoma yimuphi umsebenzi wokwakha njengoba sinquma ukuthi izisebenzi kufanele ziqedele isikhathi esingakanani ngaphambi kokuba izinto zokwakha zibe nzima ukusebenza ngazo. Ama-cellulose ether anciphisa isikhathi sokumiswa kodaka lukakhonkolo, anikeze izisebenzi isikhathi esengeziwe sokufaka nokulolonga into ngaphambi kokuba iqine.
4. Khulisa amandla
Ukwengeza i-cellulose ether ku-gypsum mortar nakho kungathuthukisa amandla omkhiqizo ophelile. Lokhu kungenxa yokuthi i-cellulose ethers yenza inethiwekhi yemeshi ngaphakathi kodaka lwegypsum, okwenza kube mancane amathuba okuthi iqhekeke, igobe noma iphuke. Lesi sici siwusizo kumaphrojekthi wokwakha lapho umkhiqizo oqediwe ubhekene nemithwalo yamandla kagesi aphezulu, njengezinhlelo zokubeka phansi, izakhiwo zophahla noma izindonga zezimboni.
5. Ukuhambisana okuhle
Enye impahla ebalulekile ye-cellulose ethers ku-gypsum mortars ukuhambisana kwayo okuhle nezinye izingxenye zengxube. I-Cellulose ether i-polymer yemvelo ehambisana nezinye izithasiselo zamakhemikhali eziningi ezivame ukusetshenziswa osikeni lwe-gypsum, njengama-retarders, ama-superplasticizers nama-ejenti afaka umoya. Lokhu kuvumela abakhi nabadwebi bezakhiwo ukuthi bakhe izingxube ze-gypsum mortar ukuze bahlangabezane nezidingo ezithile zokwakha.
Ekuphetheni
I-Cellulose ether iyisengezo esibalulekile ku-gypsum mortar, engathuthukisa ukusebenza, ukugcinwa kwamanzi, isikhathi sokusetha, amandla kanye nokuhambisana kwe-gypsum mortar. Isetshenziswa kabanzi embonini yezokwakha ukudala imikhiqizo ephezulu, engabizi futhi ehlala isikhathi eside ehlangabezana nezidingo ezidingekayo zamaphrojekthi wokwakha wanamuhla. Ngokusebenzisa ama-cellulose ethers kuma-gypsum mortars, abakhi nabadwebi bezakhiwo bangakhuphula ukukhiqiza, ukusebenza kahle kanye nokuphila isikhathi eside kwemikhiqizo yabo eqediwe, okubenza babe yingxenye ebalulekile yomkhuba wokwakha wesimanje.
