Gypsum yakabviswa sulfur ibasa rinobva mukushandiswa kwe flue gas desulfurization process pamagetsi anopiswa nemarasha kana kune dzimwe nzvimbo dzinoshandisa mafuta ane sarufa. Nekuda kwekudzivirira kwayo moto zvakanyanya, kudzivirira kupisa uye kudzivirira hunyoro, yave ichishandiswa zvakanyanya muindasitiri yekuvaka sezvinhu zvekuvaka. Zvisinei, chimwe chezvinetso zvikuru pakushandisa gypsum yakabviswa sulfur imvura yakawanda inopisa, izvo zvinogona kukonzera matambudziko akadai sekutsemuka uye kushanduka panguva yekugadzika uye kuoma. Nokudaro, pane chikonzero chekutsvaga nzira dzinoshanda dzekuderedza kupisa kwe gypsum yakabviswa sulfur uku ichichengetedza hunhu hwayo hwemakanika nehunyanzvi hwayo.
Cellulose ethers zvinhu zvinonyanya kushandiswa muindasitiri yekuvaka kuti zvinhu zvakagadzirwa nesimende zvishande zvakanaka, zvirambe zviripo kwenguva refu. Ipolymer isina chepfu, inoora, inogona kudzokororwa kubva ku cellulose, chinhu chinowanikwa zvakanyanya pasi rose. Cellulose ether inogona kugadzira chimiro chakafanana negel mumvura, izvo zvinogona kuvandudza kuchengetwa kwemvura, kuramba kudonha uye kugara kwenguva refu kwezvinhu zvakagadzirwa nesimende. Pamusoro pezvo, cellulose ethers inogonawo kukanganisa hydration uye setting process yezvinhu zvakagadzirwa negypsum, zvichikanganisa zvakanyanya mashandiro azvo emakanika.
Mhedzisiro ye cellulose ether pa gypsum hydration uye maitiro ekusimba
Gypsum imusanganiswa wecalcium sulfate dihydrate unosangana nemvura kuti ugadzire maburi akaomarara uye akaomarara ecalcium sulfate hemihydrate. Maitiro ekunyorovesa uye ekusimba kwegypsum akaomarara uye anosanganisira matanho akati wandei, anosanganisira nucleation, kukura, crystallization, uye kuomarara. Maitiro ekutanga egypsum nemvura anogadzira kupisa kwakawanda, kunonzi kupisa kwemvura. Kupisa uku kunogona kukonzera kushushikana kwekupisa uye kushomeka kwezvinhu zvakagadzirwa negypsum, izvo zvinogona kukonzera kutsemuka nezvimwe zvikanganiso.
Cellulose ethers inogona kukanganisa hydration uye setting process yegypsum kuburikidza nenzira dzakasiyana-siyana. Chekutanga, cellulose ethers inogona kuvandudza kushanda uye kuenderana kwezvinhu zvakagadzirwa negypsum nekugadzira kupararira kwakasimba uye kwakafanana mumvura. Izvi zvinoderedza zvinodiwa nemvura uye zvinowedzera flowability yezvinhu, nokudaro zvichiita kuti hydration uye setting process ifambe zvakanaka. Chechipiri, cellulose ethers inogona kubata nekuchengetedza hunyoro mukati mechinhu nekugadzira network yakaita segel, nokudaro ichivandudza kugona kwekuchengetedza mvura kwechinhu. Izvi zvinowedzera nguva ye hydration uye zvinoderedza mukana wekupisa uye shrinkage. Chechitatu, cellulose ethers inogona kunonotsa matanho ekutanga e hydration process nekubata pamusoro pe gypsum crystals uye kudzivirira kukura kwavo uye crystallization. Izvi zvinoderedza mwero wekutanga wekupisa kwe hydration uye kunonoka nguva yekuisa. Chechina, cellulose ethers inogona kuwedzera hunhu hwemakanika uye mashandiro e gypsum-based materials nekuwedzera simba rayo, kugara kwenguva refu uye kuramba kushanduka.
Zvinhu zvinokanganisa kupisa kwemvura yegypsum yakabviswa sulfuri
Kupisa kwemvura inonyungudika yegypsum yakabviswa sulfuri kunokanganiswa nezvinhu zvakasiyana-siyana, zvinosanganisira kuumbwa kwemakemikari, saizi yezvidimbu, hunyoro, tembiricha uye zvimwe zvinoshandiswa muzvinhu izvi. Kuumbwa kwemakemikari egypsum yakabviswa sulfuri kunogona kusiyana zvichienderana nerudzi rwemafuta uye maitiro ekubvisa sulfuri anoshandiswa. Kazhinji, kana tichienzanisa negypsum yechisikigo, gypsum yakabviswa sulfuri ine huwandu hwakawanda hwetsvina dzakadai secalcium sulfate hemihydrate, calcium carbonate, uye silica. Izvi zvinokanganisa mwero wemvura uye huwandu hwekupisa hunogadzirwa panguva yekuita. Hukuru hwezvidimbu uye nzvimbo chaiyo yepamusoro yegypsum yakabviswa sulfuri zvichakanganisawo mwero uye simba rekupisa kwemvura. Zvidimbu zvidiki uye nzvimbo yakakura yepamusoro inogona kuwedzera nzvimbo yekubata uye kuita kuti kuita, zvichikonzera kupisa kwakanyanya kwemvura. Hunhu hwemvura netembiricha yezvinhu zvinogonawo kukanganisa kupisa kwemvura nekudzora mwero uye huwandu hwekuita. Hunhu hwemvura hwakawanda netembiricha yakaderera zvinogona kuderedza mwero uye simba rekupisa kwemvura, nepo huwandu hwemvura hwakaderera netembiricha yakakwirira zvinogona kuwedzera mwero uye simba rekupisa kwemvura. Zvinowedzerwa zvakaita se cellulose ethers zvinogona kukanganisa kupisa kwemvura nekushanda nemakristaro egypsum uye kuchinja hunhu hwavo nemaitiro avo.
Mabhenefiti angangowanikwa ekushandisa cellulose ethers kuderedza kupisa kwemvura yegypsum yakabviswa sulfuri
Kushandisa kwedu ma ether e cellulose sekuwedzera kuderedza kupisa kwemvura ye gypsum yakabviswa sulfuri kunopa mabhenefiti akasiyana-siyana, anosanganisira:
1. Kuvandudza kushanda uye kuenderana kwezvinhu, izvo zvinobatsira pakusanganisa, kuisa uye kurongeka kwezvinhu.
2. Deredza kudiwa kwemvura uye kuwedzera kuyerera kwezvinhu, izvo zvinogona kuvandudza hunhu hwemakanika uye mashandisirwo ezvinhu.
3. Wedzera kugona kwechinhu kuchengetedza mvura uye kuwedzera nguva yemvura yechinhu, nokudaro zvichideredza kushushikana kwekupisa uye kudzikira kwemvura.
4. Kunonotsa danho rekutanga remvura, kunononotsa nguva yekusimba kwezvinhu, kuderedza kukosha kwekupisa kwemvura, uye kuvandudza kuchengetedzeka uye kunaka kwezvinhu.
5. Kuvandudza hunhu hwemakanika uye mashandiro ezvinhu, izvo zvinogona kuvandudza kugara kwenguva refu, simba uye kuramba kuchinjika kwezvinhu.
6. Cellulose ether haina chepfu, inoora uye inogona kushandiswazve, izvo zvinogona kuderedza kukanganisa nharaunda uye kukurudzira budiriro inoenderera mberi yeindasitiri yekuvaka.
mukupedzisa
Cellulose ethers zvinhu zvinovimbisa zvinogona kukanganisa hydration uye setting process ye gypsum yakabviswa mvura nekuvandudza kushanda, kugadzikana, kuchengetedza mvura uye mechanical properties yezvinhu. Kudyidzana pakati pe cellulose ethers nema gypsum crystals kunogona kuderedza kupisa kwakanyanya kwe hydration uye kunonotsa nguva yekuisa, izvo zvinogona kuvandudza kuchengetedzeka uye mhando yezvinhu. Zvisinei, kushanda kwe cellulose ethers kunogona kutsamira pazvinhu zvakaita se chemical composition, particle size, hunyoro, tembiricha uye zvimwe zvinoshandiswa muzvinhu. Tsvagiridzo yeramangwana inofanira kutarisa pakugadzirisa dosage uye kuumbwa kwe cellulose ethers kuti iwane kudzikiswa kwekupisa kwe desulfurized gypsum pasina kukanganisa mechanical properties ne mechanical properties. Pamusoro pezvo, mabhenefiti ehupfumi, zvakatipoteredza, uye magariro evanhu ekushandisa cellulose ethers anofanira kuongororwa zvakanyanya uye kuongororwa.
