Izimbotshana ezizilinganisayo zithembele esisindweni sazo ukuze zakhe isisekelo esiyisicaba, esibushelelezi nesiqinile esisekelweni, okuvumela ezinye izinto ukuthi zibekwe noma ziboshwe, ngenkathi zithola izindawo ezinkulu nezisebenzayo zokwakha. Ngakho-ke, ukugeleza okuphezulu kuyisici esibaluleke kakhulu sesimbotshana esizilinganisayo. Kumelwe futhi sibe nezinga elithile lokugcina amanzi kanye namandla okubopha, singabi nokuqhekeka kanye nokwehlukaniswa, futhi sibe ne-adiabatic kanye nokushisa okuphansi.
Udaka olujwayelekile oluzilinganisayo ludinga ukugeleza okuhle, kodwa ukugeleza kodaka lwesimende lwangempela kuvame ukuba yi-10-12cm kuphela; i-cellulose ether iyisengezo esiyinhloko sodaka oluxutshwe ngomumo, yize inani elingeziwe liphansi kakhulu, lingathuthukisa kakhulu ukusebenza kodaka, okungathuthukisa ukuqina kodaka, ukusebenza kahle, ukusebenza kokubopha kanye nokusebenza kokugcina amanzi. Inendima ebaluleke kakhulu emkhakheni wodaka oluxutshwe ngomumo.
1 Ukugeleza
I-cellulose ether inomthelela omkhulu ekugcinweni kwamanzi, ukuhambisana kanye nokusebenza kahle kwe-mortar. Ikakhulukazi njenge-mortar ezilinganisayo, ukugeleza kungenye yezinkomba eziyinhloko zokuhlola ukusebenza kwe-self-leveling. Ukugeleza kwe-mortar kungalungiswa ngokushintsha inani le-cellulose ether ngaphansi kwesisekelo sokuqinisekisa ukwakheka okuvamile kwe-mortar. Okuqukethwe okuphezulu kakhulu kuzonciphisa ukugeleza kwe-mortar, ngakho-ke, inani le-cellulose ether kufanele lilawulwe ngaphakathi kobubanzi obufanele.
2 Ukugcinwa kwamanzi
Udaka olugcina amanzi luyisibonakaliso esibalulekile sokuzinza kwezingxenye zangaphakathi zodaka lwesimende. Ukuze kwenziwe ukusabela kwejeli okugcwele amanzi, inani elifanele le-cellulose ether lingasetshenziswa isikhathi eside ukugcina amanzi odakeni. Ngokuvamile, njengoba inani le-cellulose ether landa, ukugcinwa kwamanzi kodaka nakho kuyanda. Ngaphezu kwalokho, i-viscosity ye-cellulose ether inomthelela omkhulu ekugcinweni kwamanzi kodaka; lapho i-viscosity iphakeme, ukugcinwa kwamanzi kungcono.
3 Isikhathi sokusetha
I-cellulose ether inomphumela wokuvimba ku-mortar. Njengoba okuqukethwe yi-cellulose ether kwanda, isikhathi sokusetha i-mortar sizokwelulwa. Futhi uma okuqukethwe okuphezulu kwe-cellulose ether, umphumela wokuqala we-compound hydration hysteresis wesamente usobala kakhulu.
4 Amandla okugobeka kanye namandla okucindezela
Ngokuvamile, amandla angenye yezindlela ezibalulekile zokuhlola ingxube yokuqinisa izinto eziqinisayo. Amandla okucindezela kanye namandla okuguquguquka kodaka kuzoncishiswa uma okuqukethwe kwe-cellulose ether kukhuphuka.
