Riƙewar ruwa na turmi shine maƙasudi mai mahimmanci don auna daidaiton abubuwan ciki na turmi mai gauraye sabo. Don cikakken aiwatar da aikin hydration na kayan gel, adadin madaidaicin ether na cellulose zai iya kula da danshi a cikin turmi na dogon lokaci. Gabaɗaya magana, yawan riƙe ruwa na slurry yana ƙaruwa tare da haɓaka abun ciki na ether cellulose. Tasirin riƙewar ruwa na ether cellulose zai iya hana abin da ake amfani da shi daga sha ruwa mai yawa da sauri, kuma ya hana fitar da ruwa, don tabbatar da cewa yanayin slurry yana samar da isasshen ruwa don samar da ruwa na siminti. Bugu da ƙari, danko na cellulose ether kuma yana da tasiri mai yawa akan riƙe ruwa na turmi. Mafi girman danko, mafi kyawun riƙewar ruwa. Gabaɗaya, ether cellulose tare da danko na 400mpa.s galibi ana amfani da shi a cikin turmi mai daidaita kai, wanda zai iya haɓaka aikin daidaita turmi kuma yana ƙara ƙarancin turmi.

3. Saita lokaci

Cellulose ether yana da wani tasiri na jinkirtawa akan turmi. Tare da karuwar abun ciki na ether cellulose, lokacin saita turmi yana tsawaita. Tasirin ether na cellulose a kan man siminti ya dogara ne akan matakin maye gurbin ƙungiyar alkyl, kuma ba shi da alaƙa da nauyinsa. Karamin matakin maye gurbin alkyl, mafi girman abun ciki na hydroxyl, kuma mafi bayyananniyar tasirin jinkirtawa. Kuma mafi girman abun ciki na ether cellulose, mafi mahimmancin sakamako na jinkirin tasirin fim mai rikitarwa akan farkon hydration na siminti, don haka tasirin retarding shima ya fi bayyane.

4. Ƙarfin sassauƙa da ƙarfin matsawa

Yawancin lokaci, ƙarfi yana ɗaya daga cikin mahimman ma'auni na kimantawa don magance tasirin siminti na tushen siminti akan cakuda. Lokacin da abun ciki na ether cellulose ya karu, ƙarfin matsawa da ƙarfin sassauƙa na turmi zai ragu.

5. Ƙarfin haɗin gwiwa

Cellulose ether yana da babban tasiri akan aikin haɗin gwiwa na turmi. Cellulose ether ya samar da fim din polymer tare da tasirin rufewa tsakanin sassan ciminti hydration barbashi a cikin tsarin tsarin ruwa, wanda ke inganta ƙarin ruwa a cikin fim din polymer a waje da sassan siminti, wanda ke da kyau ga cikakken hydration na ciminti, don haka inganta haɗin gwiwa. ƙarfin manna bayan hardening. A lokaci guda kuma, adadin da ya dace na ether cellulose yana haɓaka filastik da sassauci na turmi, yana rage tsattsauran ra'ayi na yanki na tsaka-tsakin tsaka-tsakin da ke tsakanin turmi da substrate, kuma yana rage ikon zamewa tsakanin musaya. Zuwa wani ɗan lokaci, ana haɓaka tasirin haɗin kai tsakanin turmi da ƙasa. Bugu da ƙari, saboda kasancewar cellulose ether a cikin manna siminti, an samar da wani yanki na musanya na musamman da kuma tsaka-tsakin tsaka-tsakin tsakanin turmi da samfurin hydration. Wannan nau'in mu'amala yana sa yankin canjin mu'amala ya zama mafi sassauƙa kuma ƙasa da ƙarfi, don haka, turmi yana da ƙarfi mai ƙarfi.
