Desulfurized gypsum ndeye-chigadzirwa che flue gasi desulfurization process pamagetsi emagetsi emarasha kana zvimwe zvidyarwa zvinoshandisa mafuta ane sulfur. Nekuda kwekuremerwa kwayo nemoto, kushomeka kwekupisa uye kushomeka kwehunyoro, yakashandiswa zvakanyanya muindasitiri yekuvaka sechinhu chekuvaka. Nekudaro, rimwe rematambudziko makuru pakushandisa desulfurized gypsum kupisa kwayo kwakanyanya kwe hydration, izvo zvinogona kutungamirira kumatambudziko akadai sekutsemuka uye deformation panguva yekumisikidza uye kuomesa maitiro. Naizvozvo, pane kudikanwa kwekutsvaga nzira dzinoshanda dzekudzikisa kupisa kwe hydration ye desulfurized gypsum uchichengetedza michina yayo uye zvivakwa.
Cellulose ethers inowanzoshandiswa kuwedzera muindasitiri yekuvaka kuvandudza kushanda, simba uye kusimba kwesimende-yakavakirwa zvinhu. Iyo isiri-chepfu, biodegradable, inogonekazve polymer inotorwa kubva ku cellulose, iyo yakanyanya kuwanda organic musanganiswa munyika. Cellulose ether inogona kuumba yakagadzikana gel-yakafanana chimiro mumvura, iyo inogona kuvandudza kuchengetwa kwemvura, sag resistance uye kuwirirana kwesimenti-based materials. Uye zvakare, cellulose ethers inogona zvakare kukanganisa hydration uye kuseta maitiro egypsum-based zvinhu, zvichiwedzera kukanganisa ma mechanic zvivakwa uye zvivakwa.
Mhedzisiro ye cellulose ether pane gypsum hydration uye solidification process
Gypsum ndeye calcium sulfate dihydrate compound inopindirana nemvura kuita dense uye yakaoma calcium sulfate hemihydrate blocks. Iyo hydration uye solidification process yegypsum yakaoma uye inosanganisira akati wandei matanho, anosanganisira nucleation, kukura, crystallization, uye kusimba. Kuita kwekutanga kwegypsum nemvura kunogadzira huwandu hwakawanda hwekupisa, hunonzi kupisa kwe hydration. Kupisa uku kunogona kukonzera kushushikana kwekushisa uye kuderera mu gypsum-based material, izvo zvinogona kutungamirira kune kuputika uye kumwe kukanganisa.
Cellulose ethers inogona kukanganisa hydration uye kuseta maitiro egypsum kuburikidza nemaitiro akati wandei. Kutanga, cellulose ethers inogona kuvandudza kushanda uye kuenderana kwegypsum-based materials nekugadzira yakagadzikana uye yakafanana dispersions mumvura. Izvi zvinoderedza zvinodiwa zvemvura uye zvinowedzera kuyerera kwezvinhu, nekudaro kufambisa iyo hydration uye kugadzirisa maitiro. Chechipiri, cellulose ethers inogona kubata uye kuchengetedza hunyoro mukati mechinhu nekugadzira gel-senge network, nekudaro ichiwedzera simba rekuchengetedza mvura. Izvi zvinowedzera nguva ye hydration uye zvinoderedza mukana wekupisa kwekushushikana uye kupera. Chechitatu, cellulose ethers inogona kunonoka matanho ekutanga eiyo hydration process nekushambadza pamusoro peiyo gypsum crystals uye kuvharidzira kukura kwavo uye crystallization. Izvi zvinoderedza chiyero chekutanga chekupisa kwe hydration uye kunonoka kuisa nguva. Chechina, cellulose ethers inogona kukwidziridza ma mechanic properties uye kushanda kwegypsum-based materials nekuwedzera simba radzo, kusimba uye kuramba deformation.
Zvinhu zvinokanganisa kupisa kwe hydration ye desulfurized gypsum
Kupisa kwe hydration ye desulfurized gypsum inokanganiswa nezvinhu zvakasiyana, zvinosanganisira kuumbwa kwemakemikari, saizi yechikamu, hunyoro hwemukati, tembiricha uye zvinowedzera zvinoshandiswa muzvinyorwa. Iko kemikari ye desulfurized gypsum inogona kusiyana zvichienderana nerudzi rwehuni uye desulfurization process inoshandiswa. Kazhinji kutaura, kana ichienzaniswa neyakasikwa gypsum, desulfurized gypsum ine yakakwira mukati metsvina senge calcium sulfate hemihydrate, calcium carbonate, uye silica. Izvi zvinokanganisa chiyero che hydration uye huwandu hwekupisa hunogadzirwa panguva yekuita. Iyo particle size uye yakananga nzvimbo yedesulfurized gypsum ichakanganisawo chiyero uye kusimba kwekupisa kwe hydration. Zvidiki zvidiki uye yakakura yakananga nzvimbo inogona kuwedzera nzvimbo yekubata uye kufambisa maitiro, zvichikonzera kupisa kwakanyanya kwe hydration. Mvura yemukati uye tembiricha yezvinhu zvinogona kukanganisa kupisa kwe hydration nekudzora chiyero uye chiyero chekuita. Mvura yakakwirira uye tembiricha yakadzika inogona kuderedza mwero uye kusimba kwekupisa kwe hydration, nepo mvura yakaderera uye tembiricha yepamusoro inogona kuwedzera mwero uye kusimba kwekupisa kwe hydration. Zviwedzere zvakadai se cellulose ethers zvinogona kukanganisa kupisa kwe hydration kuburikidza nekubatana ne gypsum crystals uye kuchinja maitiro avo uye maitiro.
Zvingango bhenefiti zvekushandisa cellulose ethers kuderedza kupisa kwe hydration ye desulfurized gypsum.
Kushandisa kwedu cellulose ethers sezvinowedzera kuderedza kupisa kwe hydration ye desulfurized gypsum kunopa akasiyana mabhenefiti, anosanganisira:
1. Kuvandudza kushanda uye kuwirirana kwezvinhu, izvo zvinobatsira kusanganisa, kuiswa uye kurongeka kwezvinhu.
2. Kuderedza kudiwa kwemvura uye kuwedzera fluidity yezvinhu, izvo zvinogona kuvandudza ma mechanical properties uye kushandiswa kwezvinhu.
3. Kuvandudza simba rekuchengetedza mvura yezvinyorwa uye kuwedzera nguva yemvura yemvura, nekudaro kuderedza zvinogona kuitika kupisa kusagadzikana uye shrinkage.
4. Kunonoka danho rekutanga re hydration, kunonoka nguva yekusimba kwezvinhu, kuderedza kukosha kwepamusoro kwekupisa kwe hydration, uye kunatsiridza kuchengetedzwa uye kunaka kwezvinhu.
5. Kuvandudza ma mechanical properties uye kushanda kwezvinhu, izvo zvinogona kuvandudza kusimba, simba uye deformation resistance yezvigadzirwa.
6. Cellulose ether haisi-chepfu, biodegradable uye inogona kuvandudzwa, iyo inogona kuderedza kukanganisa kwezvakatipoteredza uye kukurudzira kuenderera mberi kwekambani yekuvaka.
mukupedzisa
Cellulose ethers inovimbisa zvinowedzera izvo zvinogona kukanganisa hydration uye kuseta maitiro e desiccated gypsum nekuvandudza kushanda, kuwirirana, kuchengetwa kwemvura uye michina yemidziyo. Kudyidzana pakati pe cellulose ethers uye gypsum crystals kunogona kuderedza kupisa kwepamusoro kwe hydration uye kunonoka nguva yekuisa, iyo inogona kuvandudza kuchengetedzwa uye kunaka kwezvinhu. Nekudaro, kushanda kwe cellulose ethers kunogona kuenderana nezvinhu zvakaita sekuumbwa kwemakemikari, saizi yechikamu, hunyoro hwemukati, tembiricha uye zvinowedzera zvinoshandiswa mune izvo zvinhu. Tsvagiridzo yeramangwana inofanirwa kutarisisa optimize dosage uye kugadzirwa kwema cellulose ethers kuti iwane kudzikiswa kwaunoda mukupisa kwe hydration ye desulfurized gypsum pasina kukanganisa ma mechanics ayo uye zvivakwa. Pamusoro pezvo, zvingangoitika zvehupfumi, zvakatipoteredza, uye zvemagariro mabhenefiti ekushandisa cellulose ethers zvinofanirwa kuongororwa nekuongororwa.
