Ka seretseng, cellulose ether e bapala karolo ea ho boloka metsi, ho teteana, ho liehisa matla a samente a hydration, le ho ntlafatsa ts'ebetso ea kaho. Bokhoni bo botle ba ho boloka metsi bo etsa hore hydration ea samente e phethehe haholoanyane, e ka ntlafatsa viscosity e metsi ea seretse se metsi, ea eketsa matla a tlamahano ea seretse, le ho lokisa nako. Ho kenyelletsa cellulose ether ho seretse sa ho fafatsa ka mochini ho ka ntlafatsa ts'ebetso ea ho fafatsa kapa ho pompa le matla a sebopeho sa seretse. Cellulose e sebelisoa haholo e le tlatsetso ea bohlokoa ka har'a seretse se seng se kopantsoe. Ho nka tšimo ea thepa ea mohaho e le mohlala, cellulose ether e na le thepa e babatsehang e kang ho teteaneng, ho boloka metsi le ho lieha. Ka hona, thepa ea ho haha selulo ea ether e sebelisoa haholo ho ntlafatsa tlhahiso ea seretse se seng se lokiselitsoe (ho kenyeletsoa seretse se nang le metsi le seretse se omileng), resin ea PVC, joalo-joalo, pente ea latex, putty, joalo-joalo. lihlahisoa tsa thepa ea mohaho.
Cellulose e ka liehisa ts'ebetso ea hydration ea samente. Cellulose ether e fana ka seretse se nang le lisebelisoa tse fapaneng tse molemo, hape e fokotsa mocheso oa pele oa hydration oa samente le ho liehisa ts'ebetso ea hydration e matla ea samente. Sena ha se monate bakeng sa tšebeliso ea seretse libakeng tse batang. Phello ena ea ho lieha e bakoa ke ho ata ha limolek'hule tsa cellulose ether lihlahisoa tsa hydration tse kang CSH le ca(OH)2. Ka lebaka la ho eketseha ha viscosity ea tharollo ea pore, cellulose ether e fokotsa ho tsamaea ha li-ion ka tharollo, kahoo e liehisa ts'ebetso ea hydration. Ha palo ea cellulose ether e phahame ka har'a lisebelisoa tsa gel ea liminerale, phello ea ho lieha ha hydration e bonahala haholoanyane. Cellulose ether ha e liehe feela ho beha, empa hape e liehisa mokhoa o thata oa tsamaiso ea seretse sa samente. Phello e fokolisang ea cellulose ether ha e itšetlehe feela ka mahloriso a eona tsamaisong ea gel ea diminerale, empa hape le sebopeho sa lik'hemik'hale. Ha tekanyo ea methylation ea HEMC e phahame, e ntlafatsa phello ea ho fokotsa cellulose ether. Karo-karolelano ea hydrophilic substitution ho metsi-e ntseng e eketseha Phapanyetsano ea ho khutlisa e matla. Leha ho le joalo, viscosity ea cellulose ether ha e na phello e nyane ho samente hydration kinetics.
Ka keketseho ea litaba tsa hydroxypropyl methylcellulose ether, nako ea ho beha seretse e ile ea eketseha haholo. Ho na le kamano e ntle e se nang moeli pakeng tsa nako ea pele ea ho beha seretse le litaba tsa cellulose ether, le kamano e ntle ea linear pakeng tsa nako ea ho qetela ea ho beha le litaba tsa cellulose ether. Re ka laola nako ea ts'ebetso ea seretse ka ho fetola palo ea cellulose ether.
