Idethi Yokuthumela: 24, Julayi, 2023

Udaka oluzilinganisa ngokwalo lungathembela esisindweni salo ukwenza isisekelo esiyisicaba, esibushelelezi, futhi esiqinile ku-substrate yokubeka noma yokuhlanganisa ezinye izinto zokwakha, futhi ingakwazi ukwenza ukwakhiwa okukhulu nokuphumelelayo. Ngakho-ke, uketshezi oluphezulu kuyisici esibaluleke kakhulu sodaka lokuzilinganisa; Ngaphezu kwalokho, kufanele futhi ibe nezinga elithile lokugcinwa kwamanzi kanye namandla okubopha, ngaphandle kokuvela kokuhlukaniswa kwamanzi, futhi ibe nezici zokuhlukanisa nokukhuphuka okuphansi kwezinga lokushisa. Ngokuvamile, udaka lokuzilinganisa ludinga uketshezi oluhle, kodwa uketshezi lwangempela lukasimende luvame ukuba ngu-10-12cm kuphela; I-Cellulose ether iyisengezo esikhulu kudaka osulungile oluxubile. Nakuba inani elingeziwe liphansi kakhulu, lingathuthukisa kakhulu ukusebenza kodaka. Ingathuthukisa ukungaguquguquki, ukusebenza kahle, ukusebenza kwebhondi, nokusebenza kokugcinwa kwamanzi kodaka. Idlala indima ebaluleke kakhulu emkhakheni we-premix mortar.

1. I-Liquidity
I-Cellulose ether inomthelela omkhulu ekugcineni amanzi, ukungaguquguquki, nokusebenza kokwakhiwa kodaka lokuzilinganisa. Ikakhulukazi njengodaka lokuzilinganisa, ukugeleza kungenye yezinkomba eziyinhloko zokuhlola ukusebenza kokuzilinganisa. Ngokwesisekelo sokuqinisekisa ukubunjwa okujwayelekile kodaka, ukugcwala kodaka kungashintshwa ngokushintsha umthamo we-cellulose ether. Kodwa-ke, umthamo oweqile unganciphisa ukugcwala kodaka, ngakho-ke umthamo we-cellulose ether kufanele ulawulwe ngaphakathi kwebanga elifanele.

2. Ukugcinwa kwamanzi
Ukugcinwa kwamanzi kodaka kuyinkomba ebalulekile yokukala ukuzinza kwezingxenye zangaphakathi zodaka lukasimende olusanda kuxutshwa. Ukuze wenze izinto zejeli zibe namanzi ngokugcwele, inani elizwakalayo le-cellulose ether lingagcina umswakama odongeni isikhathi eside. Ngokuvamile, izinga lokugcinwa kwamanzi e-slurry likhuphuka ngokunyuka kokuqukethwe kwe-cellulose ether. Umthelela wokugcina amanzi we-cellulose ether ungavimbela i-substrate ekumunceni amanzi kakhulu noma ngokushesha kakhulu, futhi ivimbele ukuhwamuka kwamanzi, ngaleyo ndlela kuqinisekiswe ukuthi indawo ezungezile ye-slurry inikeza amanzi anele okufaka usimende. Ngaphezu kwalokho, i-viscosity ye-cellulose ether nayo inomthelela omkhulu ekugcinweni kwamanzi odaka. Ukuphakama kwe-viscosity, kungcono ukugcina amanzi. I-Cellulose ether ene-viscosity evamile engu-400mpa. s ivame ukusetshenziswa odakeni oluzilinganisa, olungathuthukisa ukusebenza kokulinganisa nokubumbana kodaka.
