Cellulose Ether- Kukora uye Thixotropy
Cellulose etherInopa dhaka rakanyorova simba rakanaka, izvo zvinogona kuwedzera kubatana pakati pedhaka rakanyorova nehwaro hwepasi, kuvandudza mashandiro edhaka anodzivirira kuyerera, uye inoshandiswa zvakanyanya mudhaka rekupurasita, dhaka rekubatanidza mataira eceramic, uye sisitimu yekudzivirira madziro ekunze. Kusimba kwe ether ye cellulose kunogonawo kuwedzera kugona kwekudzivirira kupararira uye kufanana kwezvinhu zvitsva, uye kudzivirira kupatsanurwa kwezvinhu, kupatsanurwa, uye kubuda kwemvura. Inogona kushandiswa kune kongiri yakasimbiswa nefiber, kongiri yepasi pemvura, uye kongiri inozvibatanidza.
Mhedzisiro yekukora kweether ye celluloseZvinhu zvakagadzirwa nesimende zvinobva mukunaka kwemushonga we ether we cellulose. Mumamiriro ezvinhu akafanana, kukora kweether ye cellulose, kana zvinhu zvakagadzirwa nesimende zvakagadziriswa zviri nani, viscosity yacho inowedzera kunaka. Zvisinei, kana viscosity yacho yakanyanya, zvinokanganisa kufamba zvakanaka uye kushanda zvakanaka kwezvinhu zvacho (sekupurasita mapanga). Mortar inodzienzanisa, concrete inodzibatanidza, nezvimwewo zvinoda kuyerera kwakanyanya, uye viscosity ye cellulose ether yakaderera zvikuru. Pamusoro pezvo, kukora kwe cellulose ether kuchawedzerawo kudiwa kwemvura ye substrate yesimende uye kuwedzera kugadzirwa kwemortar.
Mhinduro yemvura ye ether ine viscosity yakakura ine thixotropy yakakwira, iyo inoratidzwawo ne cellulose ether. Mhinduro yemvura ye methyl cellulose inowanzova ne pseudoplastic uye non-thixotropic flow properties yakaderera pane tembiricha yayo ye gel, asi inoratidza Newtonian flow pa low shear rate. Pasinei nerudzi uye mwero wekutsiva zvinhu zvinotsiva, pseudoplasticity inowedzera nekuwedzera kwehuremu hwemamorekuru kana kuwanda kwe cellulose ether. Nokudaro, chero bedzi kuwanda netembiricha zvichiramba zvakafanana, cellulose ethers dzine viscosity grade imwechete (zvisinei ne MC,HPMC, HEMC) dzinogara dzichiratidza hunhu hwakafanana hwe rheological. Kana tembiricha yakwira, gel yechimiro inoumbwa uye kuyerera kwakawanda kwethixotropic kunoitika.
Cellulose etherVagadziri vanokuudza kuti cellulose ether ine huwandu hwakawanda uye viscosity yakaderera ine thixotropy kunyangwe iri pasi pekupisa kwegel. Hunhu uhwu hunobatsira zvikuru pakuvaka mortar kuti igadzirise kuenzana kwayo uye kudzika kwayo. Zvinofanira kucherechedzwa kuti viscosity yakakwira.ether ye cellulose, kuchengetedza kwayo mvura kuri nani. Zvisinei, kana viscosity yakakwira, huwandu hwemamorekuru e cellulose ether hunowedzera, uye kuderera kwakafanana kwekunyunguduka kwayo. Inokanganisa zvakanyanya kuwanda uye kugona kwayo kugadzikiswa.
Cellulose Ether- Kunonoka
Cellulose etherzvinogona kuwedzera nguva yekugadzika simende kana dhaka, kunonotsa kunyorova kwesimbi yesimbi, uye kuvandudza hupenyu hwebasa rezvinhu zvitsva, nokudaro zvichivandudza kugadzikana kwekudonha kwedhaka nedhaka. Kurasikirwa nekufamba kwenguva, asi zvinogonawo kunonotsa kufambira mberi kwekuvaka.
