Cellulose etherine yakanakisa kudzokorora kwemvura, iyo inogona kudzivirira iyo unyoro mumutengo wenyoro kubva mukubuda nguva isati yasvika, uye nekupedzisira kuve nekuita kuti mitezo yedhaka, inonyanya kubatsira kuonda -Layer moter uye mvura-inobata zviyero zviyero kana dhaka yakavakwa pasi pemamiriro ekunze uye akaoma mamiriro. Iyo yekuchengetedza mvura yekuchengetedza cellulose ether inogona kuchinja maitiro echinyakare uye kugadzirisa kufambira mberi kwekuvaka. Semuenzaniso, kuvakwa kwekuparadza kunogona kuitwa pamusoro pemvura-inobata substrates pasina pre-kunyura.
Iyo viscosity, dosage, ambient tembiricha uye molecular chimiro che cellulose ether ane pesvedzero huru pakubata kwayo kwemvura. Mumamiriro ezvinhu mamwechete, iyo yakakura iyo visikopo ye cellulose ether, iri nani kuchengetwa kwemvura; Iyo yakakwira dosage, iri nani kuchengetwa kwemvura. Kazhinji, chidiki chidiki che cellulose ether chinogona kuvandudza kudzikisira kwemvura kune dhaka. Pakasvika dosage ichisvika pane imwe nguva yekuchengetwa kwemvura inowedzera, maitiro ehuwandu hwekuchengetwa kwemvura anoregedza; Kana iyo ambure tembiricha ichisimuka, kuchengetwa kwemvura kwemusangano ether kazhinji kunowanzo kuderera, asi vamwe cellulose ma cellulose vaine kuchengetedzwa kwemvura zviri nani pasi pemamiriro ekunze ekushisa; Machira ane madhigirii akadzika ezvekutsiva vegan ether ane mari yekuchengetedza mvura.
Iyo hydroxyl boka pane cellulose ether molecule uye okisijeni pane iyo yekubatanidza inoshamwaridzana nemamolekhodhi yemvura kuti abatanidze mvura yehydrogen, nekudaro ichitamba basa rakanaka mukuchengetwa kwemvura; Mamolekhou emvura uye cellulose ether molecular chetdiffission inobvumira mamorekuru emvura yekunyora uye nekukonzera mvura yakasungwa uye nekukasira mvura, iyo inovandudza kuchengetwa kwemvura kwesimendi spines; cellulose ther inovandudza iyo nyowani simenti slurry. Iyo rheological zvivakwa, porous network chimiro uye kusimudzira kweSsmotic kana iyo firimu-inoumba midziyo ye cellulose ether inotadzisa iyo yakaipa yekukanganisa kwemvura.
Cellulose ether inowana mongororo yakanyorova neyekukwazisa, iyo inogona kuwedzera zvakanyanya kugona kwekurongedza pakati pemucheka weruboshwe uye nekuvandudza basa rekutyaira. Iyo inoshandiswa zvakanyanya mulastering motsi, zvidhinha maruva marara uye kunze kwemadziro ekunze system system. Mhedzisiro inoshamisa ye cellulose ether inogonawo kuwedzera iyo anti-kupararira kugona uye kudzivisa kusagadzikana, uye inogona kushandiswa mufiriji kongiri, pasi pemvura concrete uye yekuzvibata-converting kongiri.
Iko kukonzeresa simba re cellulose ether pa coment-based zvigadzirwa zvinobva kune viscosity ye cellulose erthime. Pasi pemamiriro ezvinhu akafanana, iyo yakakwira viscosity ye cellulose ether, zviri nani zvisizvo zvezvinyorwa zvakasarudzika, asi kana visikoity yakakwira kwazvo, ichakanganisa chinhu chezvinyorwa (sekunonamira banga rinoputika ). Kuzvibata-kuyambuka dhaka uye kuzvimiririra kongiri, kunoda yakakwirira fluidity, inoda viscosity yakaderera ye cellulose ether. Uye zvakare, iyo inoshamisa mhedzisiro ye cellulose ether ichawedzera iyo yemvura inodiwa yezvinhu zvemukati-zvakavakirwa uye wedzera gobvu remuumbi.
Iyo viscosity ye cellulose gadziriso inoenderana nezvinotevera pazvinhu zvinotevera: Molecular uremu hwe cellulose ether, kusvinura, tembiricha, shear rate uye nzira yekuedza. Mumamiriro ezvinhu mamwechete, iyo yakakura kurema kwemanyorerwe e cellulose ether, yakakwira iyo visikopa yemhinduro; iyo yepamusoro yekuvhara, iyo yepamusoro iyo viscosity yemhinduro. Kana uchishandisa iyo, kutarisira kunofanirwa kutorwa kuti udzivise dosage yakawandisa uye kukanganisa kuita kwemutumbi uye kongiri; cellulose inosimbisa vhiza ye ether mhinduro ichaderera nekuwedzera kwekushisa, uye kumusoro kwekusangana, iyo yakakura pesvedzero yekushisa; cellulose etter mhinduro kazhinji inowanzo pseudoplastic fluid nenzvimbo yekutsvaira, iyo shear yekuedzwa panguva yekuedzwa, saka, iyo yekubatira ichadzikira pasi pebasa rekunze, iro rinobatsira kuna Kukakavara kuvakwa kwemutya, zvekuti doro rinogona kubata zvakanaka nekubatirana panguva imwe chete; Nekuti iyo cellulose erth mhinduro isiri yeNewtonian yemvura, apo nzira dzekuyedza, zviridzwa uye midziyo yekuedza kana midziyo yebvunzo
Cellulose ether mamorekuru anogona kugadzirisa mamwe mamorekuru emvura yezvinyorwa zvitsva pakupindirwa kweiyo molecular ketani, nokudaro inowedzera iyo yekugadzirisa mhinduro. Maketani anonyura emhereman e cellherose ether akapindirana kuti aumbe matatu-dimensional network network chimiro, icho chichaitawo kuti mhinduro yaro ive yako ine viscosity yakanaka.
Yakakwira-viscosity cellulose ether mhinduro yemvura ine yakakwira thixotropy, iyo zvakare hombe hunhu hwe cellulose ether. Mhinduro dzakasarudzika dzemethyl cellulosekazhinji ine pseudoplastics uye isina-thixotropic fluidity pazasi payo Gel tembiricha, asi ratidza Newtonian Flow Properties pamakero akaderera. Pseudoplasticality inowedzera neyekuwedzera uremu kana kusunganidzwa kwemheremelle ether, zvisinei nerudzi rwetsiva uye degree rekutsiva. Naizvozvo, mheremalose etana emagrosity gracosity giredhi, hpmc, hemc, inogara ichiratidza zvimwe zvinhu zvechitsidzo kwenguva yakareba sekusangana uye tembiricha inogara ichichengetwa nguva dzose. Matura emhando ikagadzirwa kana tembiricha yamutswa, uye zvakanyanya thisiotropic inoyerera inoitika. Yakanyanya kuderera uye yakaderera viscosity cellulose ana anairatidzira thixotropy kunyangwe pazasi pegomba tembiricha. Ichi chivakwa chinobatsira zvikuru kugadzirisa kwekuwedzera uye kusekerera mukuvakwa kwekuvaka moter. Zvinoda kutsanangurwa pano iyo yakakwira viscosity ye cellulose ether, iko zviri nani kuchengetwa kwemvura, asi kukwirira kwemvura, iyo inoenderana neyekuchinjika kwemhereme, uye kuderera kunoenderana mukushushikana kwayo, iyo ine kukanganisa kwakashata padanho rekusangana kwemota uye kuita kwekuvaka. Yakakwira iyo viscosity, iyo iri pachena iyo inoshamisa mhedzisiro pane dhaka, asi haina kuenzana. Vamwe vepakati uye vakaderera viscosity, asi iyo yakagadziridzwa cellulose ether ine zvirinani kuita mukuvandudza simba rerudzi rwerudzi rwemvura. Nekuwedzera kweViscosity, kuchengetwa kwemvura kwemasero ether kunovandudza.
