Cellulose Ether– Thickening le Thixotropy
Cellulose etherE fana ka seretse se metsi se nang le viscosity e ntle haholo, e ka eketsang haholo ho khomarela pakeng tsa seretse se metsi le lera la motheo, ho ntlafatsa ts'ebetso ea ho thibela ho phalla ha seretse, 'me e sebelisoa haholo ho rala seretse, seretse sa ceramic bonding seretse, le tsamaiso ea ka ntle ea lebota.Phello e matla ea cellulose ether e ka boela ea eketsa matla a ho thibela ho hasana le ho tšoana ha thepa e ncha, 'me ea thibela stratification ea thepa, karohano le ho phalla.E ka sebelisoa bakeng sa konkreite e matlafalitsoeng ka fiber, konkreite e ka tlas'a metsi, le konkreite e ikopanyang.

Tharollo ea metsi ea high viscosity cellulose ether e na le thixotropy e phahameng, eo hape e leng tšobotsi ea cellulose ether.Tharollo ea metsi ea methyl cellulose hangata e na le thepa ea phallo ea pseudoplastic le e seng thixotropic e tlase ho mocheso oa eona oa gel, empa e bonts'a phallo ea Newtonian ka sekhahla se tlase sa ho kuta.Ho sa tsotelehe hore na ke mofuta ofe le tekanyo ea ho nkela sebaka, pseudoplasticity e eketseha ka ho eketseha ha boima ba limolek'hule kapa khatello ea cellulose ether.Ka hona, ha feela mahloriso le mocheso li lula li le teng, li-cellulose ethers tse nang le boemo bo tšoanang ba viscosity (ho sa tsotelehe MC,HPMC, HEMC) kamehla li bonts'a lintho tse tšoanang tsa rheological.Ha mocheso o phahama, mefuta ea li-gel ea sebopeho le phallo e phahameng ea thixotropic e etsahala.
