Li-cellulose ethers li fana ka viscosity e ntle haholo ho seretse se metsi, li eketsa haholo bokhoni ba ho tlamahane ha seretse se metsi ho substrate le ho ntlafatsa ho hanyetsa ho senyeha ha seretse, 'me li sebelisoa haholo ho lilakhang seretse, seretse se kopanyang litene le mekhoa ea ho kenya letsoho ka ntle. Tšusumetso e ntseng e eketseha ea cellulose ether e ka boela ea eketsa bokhoni ba ho thibela ho qhalakanngoa le homogeneity ea thepa e sa tsoa tsoakoa, ho thibela delamination ea lintho tse bonahalang, karohano le secretion ea metsi, 'me e ka sebelisoa ka konkreite ea fiber, konkreite e ka tlas'a metsi le konkreite e ikemetseng.
Phello e matla ea li-cellulose ethers holim'a thepa ea samente e bakoa ke viscosity ea motsoako oa cellulose ether. Tlas'a maemo a tšoanang, ho phahama ha viscosity ea ether ea selulose, ho ntlafatsa ponahalo ea lintho tse fetotsoeng tsa cementitious, empa haeba viscosity e phahame haholo, e tla ama ho phalla le ho sebetsa ha thepa (mohlala, lithipa tse khomarelang). Li-mortars tse ikemetseng le konkreite e iketsetsang, e hlokang metsi a mangata, e hloka viscosity e tlaase ea cellulose ethers. Ho phaella moo, phello e matla ea cellulose ethers e eketsa tlhokahalo ea metsi ea thepa ea samente le ho eketsa chai ea seretse.
The viscosity ea tharollo ea cellulose ether e itšetlehile ka lintlha tse latelang: boima ba molek'hule ea cellulose ether, mahloriso, mocheso, sekhahla sa ho kuta le mokhoa oa teko. Tlas'a maemo a tšoanang, boima bo boholo ba molek'hule ea cellulose ether, bo phahamisa viscosity ea tharollo; e phahameng ea mahloriso, e phahameng ea viscosity ea tharollo, ha ho sebelisoa tlhokomelo e lokela ho lefshoa ho qoba dosing e feteletseng le ho ama thepa ea ho sebetsa ea seretse le konkreite; cellulose ether solution viscosity e tla fokotseha ka ho eketseha ha mocheso, 'me ha khatello e phahame, e na le tšusumetso e kholo ea mocheso; tharollo ea cellulose ether hangata ke mokelikeli oa pseudoplastic, o nang le tlhaho ea ho kuta moriri, teko e kholoanyane Ho feta tekanyo ea ho kuta ea teko, e nyenyane ea viscosity, kahoo ho kopana ha seretse ho tla fokotseha tlas'a ketso ea matla a ka ntle, e leng se loketseng ho hahoa ha seretse, e le hore seretse se ka ba le ts'ebetso e ntle le momahano ka nako e le 'ngoe; hobane tharollo ea cellulose ether ke mokelikeli o seng oa Newtonian, mekhoa ea tlhahlobo ea viscosity ea teko, lisebelisoa kapa tikoloho ea tlhahlobo, liphetho tse tšoanang tsa tlhahlobo ea tharollo ea cellulose ether li ka fapana haholo.
