Cellulose ether ndiyo inonyanya kuwedzera mudhaka yakagadzirira-yakasanganiswa.Mhando uye hunhu hwema cellulose ether hunounzwa.Mhedzisiro yehypromellose ether HPMC pazvimiro zvedhaka inodzidzwa zvakarongeka.Mhedzisiro yacho inoratidza kuti HPMC inogona kuvandudza nzvimbo inobata mvura yedhaka, kuderedza mvura yemukati, kuderedza density yemusanganiswa wedhaka, kurebesa nguva yekumisikidza, uye kuderedza kushanduka uye kumanikidza simba redhaka.Mortar ndechimwe chezvinhu zvakanyanya kushandiswa muindasitiri yekuvaka.Nekuvandudzwa kwesainzi yemidziyo uye kudiwa kwemhando yekuvaka, dhaka rave mukurumbira sekongiri yakasanganiswa, yave kutengeswa zvishoma nezvishoma.Kuenzaniswa nedhaka rakagadzirirwa nehunyanzvi hwechinyakare, kugadzirwa kwedhaka kwekutengesa kune zvakawanda zvakanakira: 1, mhando yepamusoro yechigadzirwa;2, kubudirira kwechigadzirwa chepamusoro;3, kushomeka kusvibiswa kwezvakatipoteredza, kwakanakira kuvaka kwakabudirira, parizvino kune Guangzhou, Shanghai, Beijing uye mamwe maguta ekusimudzira akagadzirira-akasanganiswa dhaka, ane hukama indasitiri zviyero, zviyero uye yenyika zviyero zvakapihwa kana zvichapihwa munguva pfupi.Musiyano mukuru pakati pedhaka rakagadzirwa-musanganiswa uye dhaka rechinyakare ndeyekuwedzerwa kwemakemikari admixture, iyo cellulose ether ndiyo inowanzoshandiswa makemikari musanganiswa.Cellulose ether inowanzo shandiswa sechinhu chekuchengetedza mvura kuvandudza Kushanda kwedhaka rakagadzirwa rakagadzirwa.Nokudaro, zvinobatsira kusarudza uye kushandisa cellulose ether zvakarurama uye kuve nechokwadi kugadzikana kwekushanda kwesamende dhaka nekuwedzera kunzwisisa kushandiswa kwemhando ye cellulose ether uye maitiro ekugadzirisa maitiro pakushanda kwesamende dhaka.
1. Mhando uye chimiro che cellulose ether cellulose ether imhando yemvura-inonyungudutswa yepolymer zvinhu, inogadzirwa ne cellulose yakasikwa nealkali solution, grafting reaction (etherification) , kushambidza, kuomesa, kugaya uye mamwe maitiro.Cellulose ethers yakakamurwa kuita ionic uye isiri-ionic mhando.Ionic cellulose ine carboxymethyl cellulose munyu, nepo isiri-ionic cellulose ine hydroxyethyl cellulose ethers, hydroxypropyl methyl cellulose ethers, Methyl cellulose ethers, nezvimwewo.Nekuti ionic cellulose ether (carboxymethyl cellulose) haina kugadzikana pamberi pe calcium ions, haiwanzo shandiswa muzvigadzirwa zvehupfu yakaoma zvine simende uye hydrated lime, cellulose ethers inoshandiswa mudhaka rakaoma inonyanya kushandiswa kwehydroxyethyl methyl cellulose ethers (HEMC). ) uye hydroxypropyl methyl cellulose ethers (HPMC) , mugove wavo wemusika unopfuura 90% 2. Mhedzisiro ye cellulose ether pane zvinhu zvemasimenti edhaka 1. The raw material cellulose ether yekuedza: yakagadzirwa naShandong Gomez Chemical Co., Ltd. viscosity: 75000;Simende: 32.5 giredhi composite simende;Jecha: jecha riri pakati nepakati;Fly Ash: II giredhi.2 mhinduro dzebvunzo 1. Mvura-inoderedza mhedzisiro ye cellulose ether mufananidzo 2 ihukama pakati pekusagadzikana kwedhaka uye zviri mukati cellulose ether mune imwechete yekusanganiswa chikamu, zvishoma nezvishoma yakawedzera.Kana 0.3 ‰ ichiwedzerwa, kuwirirana kwedhaka kunowedzera inenge 50% , iyo inoratidza kuti cellulose ether inogona kuvandudza kushanda kwevhu, nekuwedzera kwezvinyorwa zve cellulose ether, mvura inoshandiswa inogona kuderedzwa zvishoma nezvishoma. .Inogona kutaridzirwa kuti cellulose ether ine imwe nzira yekuderedza mvura.2. Mvura inobata dhaka inobata mvura inoreva kukwanisa kwedhaka kubata mvura, uyewo indekisi yekushanda kuyera kugadzikana kwedhaka resimende itsva panguva yekufambisa uye kupaka.Kuchengetwa kwemvura kwedhaka rakagadzirwa-yakasanganiswa kunogona kuyerwa neiyo indekisi yeDelamination uye kuchengetwa kwemvura, asi haina kusimba zvakakwana kuratidza mutsauko nekuda kwekuwedzera mvura yekuchengetedza.Muedzo wekuchengetedza mvura ndeyekuverenga chiyero chekuchengetedza mvura nekuyera shanduko yemhando yepepa resefa isati yasvika uye mushure mekusangana nenzvimbo yakatarwa yedhaka mune imwe nguva yenguva.Nekuda kwemvura yakanaka yekunyura kwepepa resefa, kunyangwe kuchengetwa kwemvura kwedhaka kwakakwira zvakanyanya, pepa resefa rinogona kuramba richitora mvura yedhaka, saka mwero wekuchengetedza mvura unogona kunyatso ratidza kuchengetwa kwemvura kwedhaka, kunowedzera kuchengetwa kwemvura. chiyero, zviri nani kuchengetedza mvura.
