I-Desulfurized Gypsum iwumkhiqizo wenqubo ye-flue gas desulfurization ezimbonini zamandla aphehlwa ngamalahle noma ezinye izitshalo ezisebenzisa izibaseli ezinesulfure.Ngenxa yokumelana nomlilo omkhulu, ukumelana nokushisa nokumelana nomswakama, sekusetshenziswe kabanzi embonini yokwakha njengento yokwakha.Kodwa-ke, enye yezinselelo ezinkulu ekusebenziseni i-gypsum ye-desulfurized ukushisa kwayo okuphezulu kwe-hydration, okungaholela ezinkingeni ezifana nokuqhekeka nokuguqulwa ngesikhathi sokusetha kanye nenqubo yokuqina.Ngakho-ke, kunesidingo sokuthola izindlela ezisebenzayo zokunciphisa ukushisa kwe-hydration ye-gypsum desulfurized ngenkathi igcina izakhiwo zayo zemishini kanye nezakhiwo.
Ama-cellulose ethers ayizithasiselo ezivame ukusetshenziswa embonini yezokwakha ukuze kuthuthukiswe ukusebenza, amandla nokuqina kwezinto ezisekelwe kusimende.I-polymer engenabo ubuthi, ebolayo, evuselelekayo etholakala ku-cellulose, inhlanganisela yezinto eziphilayo egcwele kakhulu emhlabeni.I-cellulose ether ingakha isakhiwo esizinzile esifana nejeli emanzini, esingathuthukisa ukugcinwa kwamanzi, ukumelana nokucwila kanye nokuvumelana kwezinto ezisekelwe kusimende.Ngaphezu kwalokho, ama-cellulose ethers angaphinda athinte izinqubo ze-hydration kanye nokusethwa kwezinto ezisekelwe ku-gypsum, ziphinde zibe nomthelela ekusebenzeni kwazo kwemishini kanye nezakhiwo.
Umthelela we-cellulose ether ku-gypsum hydration kanye nenqubo yokuqinisa
I-Gypsum iyinhlanganisela ye-calcium sulfate dihydrate esabela emanzini ukuze yakhe amabhlogo aminyene futhi aqinile e-calcium sulfate hemihydrate.Inqubo ye-hydration kanye ne-solication ye-gypsum iyinkimbinkimbi futhi ihilela izigaba ezimbalwa, ezihlanganisa i-nucleation, ukukhula, i-crystallization, nokuqinisa.Ukusabela kokuqala kwe-gypsum namanzi kukhiqiza inani elikhulu lokushisa, okubizwa ngokuthi ukushisa kwe-hydration.Lokhu kushisa kungabangela ukucindezeleka okushisayo kanye nokuncipha kwezinto ezisekelwe ku-gypsum, okungaholela ekuqhekekeni nokunye ukukhubazeka.
Ama-cellulose ether angathinta ukugeleza nokusethwa kwezinqubo ze-gypsum ngokusebenzisa izindlela ezimbalwa.Okokuqala, ama-cellulose ether angathuthukisa ukusebenza kanye nokuvumelana kwezinto ezisekelwe ku-gypsum ngokwenza ama-dispersions azinzile futhi afanayo emanzini.Lokhu kunciphisa izidingo zamanzi futhi kwandisa ukugeleza kwezinto, ngaleyo ndlela kube lula inqubo ye-hydration kanye nokubeka.Okwesibili, ama-cellulose ether angakwazi ukubamba futhi agcine umswakama ngaphakathi kwempahla ngokwenza inethiwekhi efana nejeli, ngaleyo ndlela ithuthukise umthamo wokugcina amanzi.Lokhu kwandisa isikhathi se-hydration futhi kunciphisa amandla okucindezeleka okushisayo nokuncipha.Okwesithathu, ama-cellulose ether angabambezela izigaba zakuqala zenqubo ye-hydration ngokukhangisa phezu kwamakristalu e-gypsum futhi avimbele ukukhula nokucwebezela kwawo.Lokhu kunciphisa izinga lokuqala lokushisa kwe-hydration kanye nokulibaziseka isikhathi sokusetha.Okwesine, ama-cellulose ethers angathuthukisa izakhiwo zemishini nokusebenza kwezinto ezisekelwe ku-gypsum ngokukhulisa amandla azo, ukuqina kanye nokumelana nokuguquguquka.
Izinto ezithinta ukushisa kwe-hydration ye-gypsum desulfurized
Ukushisa kwe-hydration ye-gypsum e-desulfurized kuthinteka yizinto ezihlukahlukene, okuhlanganisa ukwakheka kwamakhemikhali, usayizi wezinhlayiya, okuqukethwe komswakama, izinga lokushisa kanye nezithasiselo ezisetshenziswa endabeni.Ukwakheka kwamakhemikhali egypsum enziwe nge-desulfurized kungahluka kuye ngohlobo lwamafutha kanye nenqubo ye-desulfurization esetshenzisiwe.Ngokuvamile, uma kuqhathaniswa ne-gypsum yemvelo, i-gypsum ye-desulfurized inokuqukethwe okuphezulu kokungcola okufana ne-calcium sulfate hemihydrate, i-calcium carbonate, ne-silica.Lokhu kuthinta izinga le-hydration kanye nenani lokushisa elikhiqizwa ngesikhathi sokusabela.Ubukhulu bezinhlayiyana kanye nendawo ethile yendawo ye-gypsum e-desulfurized kuzophinde kuthinte izinga kanye nokuqina kokushisa kwe-hydration.Izinhlayiya ezincane nendawo ethize emikhulu ingandisa indawo yokuxhumana futhi yenze kube lula ukusabela, okuholela ekushiseni okuphezulu kwe-hydration.Okuqukethwe kwamanzi kanye nezinga lokushisa kwezinto kungathinta ukushisa kwe-hydration ngokulawula izinga kanye nezinga lokusabela.Okuqukethwe kwamanzi aphezulu kanye nezinga lokushisa eliphansi kunganciphisa izinga kanye namandla okushisa kwe-hydration, kuyilapho okuqukethwe kwamanzi aphansi kanye nezinga lokushisa eliphakeme kungakhuphula izinga kanye namandla okushisa kwe-hydration.Izithasiselo ezifana nama-cellulose ethers zingathinta ukushisa kwe-hydration ngokusebenzisana namakristalu e-gypsum nokuguqula izakhiwo nokuziphatha kwawo.
Izinzuzo ezingaba khona zokusebenzisa i-cellulose ethers ukunciphisa ukushisa kwe-hydration ye-gypsum desulfurized
Ukusebenzisa kwethu ama-cellulose ethers njengezithasiselo zokunciphisa ukushisa kwe-hydration ye-gypsum desulfurized kunikeza izinzuzo ezihlukahlukene ezingaba khona, kuhlanganise:
1. Thuthukisa ukusebenza kanye nokuvumelana kwezinto, okuzuzisa ukuxuba, ukubekwa nokuhlelwa kwezinto.
2. Yehlisa isidingo samanzi futhi andise fluidity of materials, okungase ngcono izakhiwo mechanical kanye nokusebenziseka materials.
3. Thuthukisa umthamo wokugcina amanzi wento esetshenziswayo futhi welule isikhathi sokugeleza kwempahla, ngaleyo ndlela wehlise ingcindezi yokushisa engaba khona kanye nokuncipha.
4. Ukubambezeleka kwesigaba sokuqala sokufakwa kwe-hydration, ukubambezela isikhathi sokuqiniswa kwezinto, ukunciphisa inani eliphakeme lokushisa kwe-hydration, futhi kuthuthukise ukuphepha kanye nekhwalithi yezinto zokwakha.
5. Thuthukisa izakhiwo zemishini nokusebenza kwezinto, ezingathuthukisa ukuqina, amandla kanye nokumelana nokuguquguquka kwezinto.
6. I-Cellulose ether ayinabo ubuthi, iyakwazi ukubola futhi ivuseleleke, enganciphisa umthelela emvelweni futhi ikhuthaze intuthuko esimeme yemboni yezokwakha.
Ekuphetheni
I-Cellulose ethers izithasiselo ezithembisayo ezingaba nomthelela ku-hydration kanye nezinqubo zokumisa ze-gypsum ekhishiwe ngokuthuthukisa ukusebenza, ukungaguquguquki, ukugcinwa kwamanzi kanye nezakhiwo zemishini zento.Ukusebenzisana phakathi kwama-cellulose ethers namakristalu e-gypsum kunganciphisa ukushisa okuphezulu kwe-hydration futhi kubambezele isikhathi sokusetha, okungathuthukisa ukuphepha nekhwalithi yezinto.Nokho, ukusebenza kahle kwama-cellulose ether kungase kuncike ezintweni ezifana nokwakheka kwamakhemikhali, usayizi wezinhlayiyana, okuqukethwe umswakama, izinga lokushisa kanye nezithasiselo ezisetshenziswa endabeni.Ucwaningo lwesikhathi esizayo kufanele lugxile ekwandiseni umthamo kanye nokwakhiwa kwama-cellulose ethers ukuze kuzuzwe ukuncipha okufunayo ekushiseni kwe-hydration ye-desulfurized gypsum ngaphandle kokuthikameze izakhiwo zayo zemishini kanye nezakhiwo.Ukwengeza, izinzuzo ezingaba khona zezomnotho, ezemvelo, nezenhlalo zokusebenzisa ama-cellulose ethers kufanele kuqhutshekwe kuhlolisiswe futhi kuhlolwe.
