I-Desulfurized gypsum yimveliso ephuma kwi-flue gas desulfurization kwimizi-mveliso yamandla esebenza ngamalahle okanye ezinye izityalo ezisebenzisa amafutha anesulfure.Ngenxa yokumelana nomlilo ophezulu, ukumelana nobushushu kunye nokumelana nomswakama, sele isetyenziswe ngokubanzi kwishishini lokwakha njengento yokwakha.Nangona kunjalo, enye yeengxaki ezinkulu ekusebenziseni i-gypsum ye-desulfurized kubushushu bayo obuphezulu be-hydration, obunokukhokelela kwiingxaki ezifana nokuqhekeka kunye nokuguqulwa ngexesha lokumisela kunye nenkqubo yokuqina.Ngoko ke, kukho imfuneko yokufumana iindlela ezisebenzayo zokunciphisa ukushisa kwe-hydration ye-gypsum desulfurized ngelixa igcina iimpawu zayo zomatshini kunye neempawu.
I-cellulose ethers zisetyenziswa ngokuqhelekileyo izongezo kwishishini lokwakha ukuphucula ukusebenza, amandla kunye nokuqina kwezinto ezisekelwe kwi-samente.Yi-non-toxic, i-biodegradable, i-polymer ehlaziywayo evela kwi-cellulose, eyona khompawundi ininzi yezinto eziphilayo emhlabeni.I-ether ye-cellulose inokwenza i-gel-isakhiwo esizinzile emanzini, esinokuphucula ukugcinwa kwamanzi, ukunyanzeliswa kwe-sag kunye nokuhambelana kwezinto ezisekelwe kwi-samente.Ukongezelela, i-cellulose ethers inokuchaphazela i-hydration kunye neenkqubo zokumisela izinto ezisekelwe kwi-gypsum, zichaphazela ngakumbi iipropati zabo zomatshini kunye neempawu.
Impembelelo ye-cellulose ether kwi-gypsum hydration kunye nenkqubo yokuqinisa
IGypsum yikhalsiyam sulfate dihydrate ikhompawundi edibana namanzi yenze iibhloko ezishinyeneyo neziqinileyo ze-calcium sulfate hemihydrate.I-hydration kunye nenkqubo yokuqinisa i-gypsum iyinkimbinkimbi kwaye ibandakanya izigaba ezininzi, kuquka i-nucleation, ukukhula, i-crystallization, kunye nokuqina.Ukusabela kokuqala kwegypsum kunye namanzi kubangela ubushushu obukhulu, obubizwa ngokuba bubushushu be-hydration.Lo bushushu bunokubangela uxinzelelo lwe-thermal kunye nokunciphisa kwizinto ezisekelwe kwi-gypsum, ezinokuthi zikhokelela ekuqhekekeni kunye nezinye iziphene.
I-cellulose ethers inokuchaphazela i-hydration kunye nokumisela iinkqubo ze-gypsum ngeendlela ezininzi.Okokuqala, i-cellulose ethers inokuphucula ukusebenza kunye nokuhambelana kwezinto ezisekelwe kwi-gypsum ngokwenza i-dispersions ezinzileyo kunye nefanayo emanzini.Oku kunciphisa iimfuno zamanzi kunye nokwandisa ukuhamba kwezinto eziphathekayo, ngaloo ndlela kuququzelela inkqubo ye-hydration kunye nokumisela.Okwesibini, i-cellulose ethers inokubamba kwaye igcine umswakama ngaphakathi kwezinto ngokwenza inethiwekhi efana nejel, ngaloo ndlela iphucula amandla okugcina amanzi.Oku kwandisa ixesha le-hydration kwaye kunciphisa amandla oxinzelelo lwe-thermal kunye nokunciphisa.Okwesithathu, ii-cellulose ethers zinokulibazisa amanqanaba okuqala enkqubo yokufakwa kwamanzi ngokubhengeza kumphezulu weekristale zegypsum kunye nokuthintela ukukhula kwazo kunye necrystallization.Oku kunciphisa izinga lokuqala lobushushu be-hydration kunye nokulibaziseka kwexesha lokumisela.Okwesine, i-cellulose ethers inokuphucula iimpawu zomatshini kunye nokusebenza kwezinto ezisekelwe kwi-gypsum ngokunyusa amandla abo, ukuqina kunye nokuchasana nokuguqulwa.
Izinto ezichaphazela ukushisa kwe-hydration ye-gypsum desulfurized
Ukushisa kwe-hydration ye-gypsum ye-desulfurized kuchaphazeleka yizinto ezahlukeneyo, kubandakanywa ukubunjwa kweekhemikhali, ubungakanani bamasuntswana, ubumanzi, ubushushu kunye nezongezo ezisetyenziswa kwizinto eziphathekayo.Ukwakhiwa kweekhemikhali ze-gypsum ye-desulfurized kunokwahluka ngokuxhomekeke kuhlobo lwamafutha kunye nenkqubo ye-desulfurization esetyenzisiweyo.Ngokuqhelekileyo, xa kuthelekiswa ne-gypsum yendalo, i-gypsum ye-desulfurized inemixholo ephezulu yokungcola okufana ne-calcium sulfate hemihydrate, i-calcium carbonate, kunye ne-silica.Oku kuchaphazela iqondo le-hydration kunye nomlinganiselo wobushushu owenziwe ngexesha lokuphendula.Ubungakanani be-particle kunye nommandla othile we-gypsum desulfurized uya kuchaphazela izinga kunye nokuqina kobushushu be-hydration.Amasuntswana amancinci kunye nendawo enkulu yendawo ethile inokunyusa indawo yoqhagamshelwano kwaye iququzelele ukusabela, okubangelwa ukushisa okuphezulu kwe-hydration.Umxholo wamanzi kunye nobushushu bezinto eziphathekayo kunokuchaphazela ukushisa kwe-hydration ngokulawula izinga kunye nobungakanani bokusabela.Umxholo wamanzi aphezulu kunye nokushisa okuphantsi kunokunciphisa izinga kunye nokuqina kobushushu be-hydration, ngelixa umxholo wamanzi ophantsi kunye nobushushu obuphezulu kunokunyusa izinga kunye nokuqina kobushushu be-hydration.Izongezo ezifana ne-cellulose ethers zinokuchaphazela ukushisa kwe-hydration ngokusebenzisana neekristale ze-gypsum kunye nokutshintsha iimpawu zabo kunye nokuziphatha.
