I-Gypsurized Gypsum ingumkhiqizo wenqubo yegesi ye-Flue Deselfurization ezitshalweni zamandla wamalahle noma ezinye izitshalo ezisebenzisa amafutha aqukethe ama-sulfur. Ngenxa yokumelana nomlilo okuphezulu, ukumelana nokushisa kanye nokumelana nokuswakama, kusetshenziswe kabanzi embonini yezokwakha njengezinto zokwakha. Kodwa-ke, enye yezinselelo ezinkulu ekusebenziseni i-gypsurum esetshenzisiwe ukushisa kwayo okuphezulu kwe-hydration, okungaholela ezinkingeni ezinjengokuqhekeka kanye nokodonga ngesikhathi senqubo yokuqina. Ngakho-ke, kunesidingo sokuthola izindlela eziphumelelayo zokunciphisa ukushisa kwe-hydration ye-gypsurum esetshenzisiwe ngenkathi ugcina izakhiwo zayo zemishini kanye nezakhiwo.
AbakwaCellulose Abaphotha bavame ukusetshenziswa izengezo embonini yezokwakha ukuze bathuthukise ukuwenza, amandla nokuqina kwezinto zokwenziwa kosimende. Kuyinto engekho-anobuthi, enobuthi, evuselelekayo ethathwe kususelwa ku-cellulose, i-organic action eningi kakhulu emhlabeni. I-Cellulose Ether ingakha isakhiwo esilinganiselwe se-gel emanzini, esingathuthukisa ukugcinwa kwamanzi, ukumelana kwe-sag nokuvumelana kwezinto zokwenziwa komoya. Ngaphezu kwalokho, izithambiso ze-cellulose nazo zingathinta i-hydration kanye nokusetha izinqubo zezinto zokwakha ezisekelwe e-gypsum, zithinta futhi izakhiwo zempahla nezakhiwo zazo.
Umphumela we-cellulose ether ku-gypsum hydration kanye nenqubo yokuqina
I-Gypsum iyisizinda se-calcium sulfate dihydrate compound esiphenduke ngamanzi ukwenza ama-hemihydrate ama-hemium Inqubo ye-hydration ne-gypsum iyinkimbinkimbi futhi ifaka izigaba eziningana, kufaka phakathi i-nucleation, ukukhula, i-crystallization, nokuqina. Ukusabela kokuqala kwe-gypsum namanzi kwakha inani elikhulu lokushisa, okubizwa ngokuthi ukushisa kwe-hydration. Lokhu kushisa kungadala ukucindezelwa okushisayo kanye nokujikisa izinto ezisekelwe e-gypsum, ezingaholela emihlangeni nakwezinye izici.
I-Cellulose Afers ingathinta i-hydration kanye nokubeka izinqubo ze-gypsum ngokusebenzisa izindlela eziningana. Okokuqala, izithambiso ze-cellulose zingathuthukisa ukuwenza nokuvumelana kwezinto ezisekelwa yi-gypsum ngokwakha ukuhlakazwa okuzinzile nokufana kwamanzi emanzini. Lokhu kunciphisa izidingo zamanzi futhi kwandisa ukugeleza okuqukethwe, ngaleyo ndlela kusiza inqubo yokusetha kanye nokusetha. Okwesibili, izithambiso ze-cellulose zingathatha futhi zigcine umswakama ngaphakathi kwezinto zokwakha inethiwekhi ye-gel, ngaleyo ndlela ethuthukisa amandla okugcina amanzi. Lesi sikhathi sandulela isikhathi se-hydration futhi sinciphise amandla okuxineka okushisayo kanye ne-shrinkage. Okwesithathu, izithambiso ze-cellulose zingabambezela izigaba zokuqala zenqubo ye-hydration nge-adderbing ngaphezulu kwamakrestali e-gypsum futhi kuvimbela ukukhula kwawo kanye ne-crystallization yazo. Lokhu kunciphisa inani lokuqala lokushisa kwe-hydration nokubambezeleka kwesikhathi isikhathi. Okwesine, izimpi ze-cellulose zingathuthukisa izakhiwo zemishini kanye nokwenza izinto ezisekelwa yi-gypsum ngokwandisa amandla azo, ukuqina kanye nokumelana noshintsho.
Izici ezithinta ukushisa kwe-hydration ye-gypsururized desulfurized
Ukushisa kwe-hydration kwe-gypsurum esuselwa ekusukeni kuyathinteka yizici ezahlukahlukene, kufaka phakathi ukwakheka kwamakhemikhali, usayizi wezinhlayiyana, okuqukethwe umswakama, izinga lokushisa elisetshenziswe ezintweni ezibonakalayo. Ukwakheka kwamakhemikhali kwe-gypsuri esusurifurized kungahluka ngokuya ngohlobo lwamafutha kanye nenqubo yokususela amandla esetshenzisiwe. Ngokuvamile, uma kuqhathaniswa ne-gypsum yemvelo, i-gypsurum ekhuphukile enokuqukethwe okuphezulu kokungcola okufana ne-calcium sulfate hemihydrate, i-calcium carbonate, kanye ne-silica. Lokhu kuthinta izinga le-hydration kanye nenani lokushisa elenziwe ngesikhathi sokuphendula. Ubukhulu bezinhlayiyana kanye nendawo ethize yendawo ye-gypsurumid izothinta isilinganiso nobukhulu bokushisa kwe-hydration. Izinhlayiya ezincane kanye nendawo ekhethekile engaphezulu engaphezulu zingakhulisa indawo yokuxhumana futhi zisebenze ukusabela, okuphumela ekushiseni okuphezulu kwe-hydration. Okuqukethwe kwamanzi kanye nokushisa kokuqukethwe kungathinta nokushisa kwe-hydration ngokulawula isilinganiso nobukhulu bokuphendula. Okuqukethwe kwamanzi okuphezulu namazinga okushisa aphansi kunganciphisa isilinganiso nokuqina kokushisa kwe-hydration, ngenkathi okuqukethwe okuphansi kwamanzi namazinga okushisa aphezulu kungakhulisa izinga nobukhulu bokushisa kwe-hydration. Izithasiselo ezinjenge-cellulose afers zingathinta ukushisa kwe-hydration ngokuxhumana namakrestali e-gypsum futhi kuguqule izakhiwo zazo nokuziphatha.
Izinzuzo ezingaba khona zokusebenzisa i-cellulose izithathekisa ukunciphisa ukushisa kwe-hydration ye-gypsurum esetshenzisiwe
Ukusetshenziswa kwethu izithambiso ze-cellulose njengezengezo zokunciphisa ukushisa kwe-hydration ye-gypsurum ekhuphukile kunikeza izinzuzo ezingaba khona, kufaka phakathi:
1. Thuthukisa ukusebenziseka nokuvumelana kwezinto zokwakha, okuzuzisa ukuxubana, ukubekwa kanye nokuhlelwa kwezinto zokwakha.
2. Yehlisa ukufunwa kwamanzi futhi ukhuphule uketshezi lwezinto zokwakha, ezingathuthukisa izakhiwo zemishini nokusebenziseka kwezinto zokwakha.
3. Khulisa amandla okugcinwa kwamanzi okuqukethwe futhi unwebe isikhathi se-hydration, ngaleyo ndlela kunciphisa ukucindezelwa okungaba khona okungekho khona kanye ne-shrinkage.
4. Ukubambezela isigaba sokuqala se-hydration, ukubambezela isikhathi sokuqina kwezinto zokwakha, ukunciphisa inani eliphakeme lokushisa kwe-hydration, futhi uthuthukise ukuphepha nekhwalithi yezinto zokwakha.
I-5. Thuthukisa izakhiwo zemishini kanye nokwenza izinto zokwakha, ezingathuthukisa ukuqina, amandla nokumelana kwezinto zokwakha.

Ekuphetheni
I-Cellulose Afers ithembise izengezo ezingathonya i-hydration kanye nokusetha izinqubo ze-gypsum efihliwe ngokwenza ngcono ukuwenza, ukuvumelana, ukugcinwa kwamanzi kanye nezindawo zemishini zezinto ezibonakalayo. Ukuxhumana phakathi kwezitha ze-cellulose kanye nezinhlaka ze-gypsum kunganciphisa ukushisa okuphezulu kwe-hydration futhi kubambezele isikhathi sokusetha, esingathuthukisa ukuphepha nekhwalithi yezinto ezibonakalayo. Kodwa-ke, ukusebenza kahle kwezithambekele ze-cellulose kungahle kuncike ezintweni ezifana nokwakheka kwamakhemikhali, usayizi wezinhlayiyana, okuqukethwe umswakama, izinga lokushisa kanye nezithasiselo ezisetshenziswe ezintweni ezibonakalayo. Ucwaningo lwesikhathi esizayo kufanele lugxile ekuthuthukiseni umthamo kanye nokwakhiwa kwezindlebe ze-cellulose ukufezekisa ukuncishiswa okufisayo ekushiseni kwe-gypsuring nezakhiwo ezithinta imishini. Ngaphezu kwalokho, izinzuzo zezomnotho ezingaba khona, ezemvelo kanye nezinzuzo zezenhlalo zokusebenzisa izithambisi ze-cellulose kufanele zihlolwe futhi zihlolwe.
