I-Titanium gypsum uhlobo lwensalela yemfucuza ene-dihydrate gypsum njengengxenye eyinhloko, ekhiqizwa ngokungeza i-lime (noma i-calcium carbonate) ukuze kuncishiswe inani elikhulu lamanzi angcolile e-asidi ukuze kuphathwe amanzi angcolile e-asidi lapho i-titanium dioxide ikhiqizwa ngendlela ye-sulfuric acid. Ukukhishwa kwe-titanium gypsum akugcini nje ngokuthatha indawo eningi futhi kungcolise imvelo, kodwa futhi kubangela umthwalo omkhulu wezomnotho emabhizinisini e-titanium dioxide. I-Titanium gypsum ingasetshenziswa ukwenza i-cement retarder ngemuva kokucutshungulwa ngomshini wokugaya. UGuilin Hongcheng ungumkhiqizi ochwepheshe wei-titaniumumshini wokugaya i-gypsum.Okulandelayo kuchaza indlela yokulungisa izinto zokwakha ze-titanium gypsum ezihlanganisiwe ngosimende ngokusebenza kahle.

1. Uyini umphumela wokufaka izingxube ezahlukahlukene ku-titanium gypsum ekusebenzeni kwayo?

Isici samandla se-titanium gypsum ngemva kokuguqulwa ngokomzimba sinesikhala esithile nese-gypsum yemvelo kanye nenye i-gypsum yamakhemikhali. Ezinye izithasiselo kumele zengezwe ukuze kuthuthukiswe isici samandla se-titanium gypsum. Izithasiselo ezisetshenziswayo zifaka phakathi umlotha wokususa i-sulfurization, umlotha ompukane, i-water quenched slag, i-alum, i-water reducer kanye ne-retarder.

Uma i-slag ecishiwe ngamanzi isetshenziswa njenge-aggregate elula, lapho okuqukethwe kungaphansi kuka-40%, ngeke kuthinte amandla omkhiqizo we-titanium gypsum, futhi kunganciphisa ngempumelelo ubuningi bomkhiqizo; Uma okuqukethwe kwe-fly ash kungaphansi kuka-30%, kunomthelela omncane ekuthuthukiseni amandla e-titanium gypsum, kodwa uma okuqukethwe kwe-fly ash kungaphezu kuka-30%, kuzonciphisa amandla e-titanium gypsum, futhi i-fly ash iyasiza ekuthuthukiseni amandla asekupheleni kwe-titanium gypsum (7d). Umlotha osusiwe ungaba ngcono kakhulu amandla e-titanium gypsum. Ngokwanda kokuqukethwe kwawo, amandla emikhiqizo ye-titanium gypsum angathuthukiswa kakhulu. I-Alum ingathuthukisa ngempumelelo amandla e-titanium gypsum, futhi uma okuqukethwe kungu-3%, umphumela uba ngcono kakhulu; Inani lamanzi engeziwe linomthelela osobala emandleni e-titanium gypsum. Ngokwanda kwenani lamanzi engeziwe, amandla esampula ancipha kakhulu. Ngakho-ke, ngenkathi kuqinisekiswa ukugeleza kwe-gypsum paste, lapho inani lamanzi engeziwe liphansi, kungcono.

Njenge-aggregate elula, i-slag ecishiwe ngamanzi ingathuthukisa ubuningi bemikhiqizo yesilingo se-titanium gypsum. Umlotha ocishiwe, umlotha ompukane kanye ne-alum kungathuthukisa kakhulu ukusebenza kwamandla kwe-titanium gypsum. Ngakho-ke, i-titanium gypsum, umlotha ocishiwe kanye nomlotha ompukane kukhethwa njengempuphu, i-slag ecishiwe ngamanzi isetshenziswa njenge-aggregate ekhanyayo, kanti i-alum, i-melamine kanye ne-citric acid kusetshenziswa njengezithasiselo. Amapharamitha amahle kakhulu atholakala ngokushintsha isilinganiso sempuphu. Ingxenye ye-aggregate ingu-40% wempuphu, ingxenye ye-alum esithasiselweni ingu-3% wempuphu, ingxenye ye-melamine ne-citric acid ingu-1% ngokulandelana, kanti ukwengezwa kwe-titanium gypsum engu-70% kanye nomlotha ocishiwe ongu-30%, ukusebenza kwezinto ezisimende kuhle.

2. Ungayilungisa kanjani i-titanium gypsum composite cementitious material esebenza kahle?

Ngemva kokufaka i-calcining amahora ama-2 ku-600℃, i-titanium gypsum ihlanganiswa nomlotha ompukane, i-slag kanye ne-simende ukuze kufinyezwe isikhathi sokuqala sokusetha kwe-composite sibe ngamahora ama-3, isikhathi sokugcina sokusetha sibe ngamahora ama-5, kanti amandla e-flexural angu-28d kanye namandla okucindezela afinyelela ku-4.3MPa kanye no-13.6MPa ngokulandelana. Nge-titanium gypsum kanye ne-slag njengezingxenye eziyisisekelo, i-cement clinker kanye ne-composite early strength water reducer zingasetshenziswa ukulungiselela usimende ngokusebenza okuhle kakhulu, futhi amandla ayo kanye nokumelana namanzi kusobala ukuthi kuphakeme kunokwakha i-gypsum. Ucwaningo lubonisa ukuthi amandla e-titanium gypsum mixed cementitious material ngemva kokulungiswa kwemvelo izinsuku ezingama-28 angahlangabezana nezidingo zezinto zokwakha odongeni kanye nezinto ezixubile zomgwaqo kamasipala, izinga layo lokuncibilika lingaphansi kuka-20% we-building gypsum, kanti izinga layo lokumunca amanzi licishe libe ngu-50% we-building gypsum, okubonisa ukuthi izinto ze-titanium gypsum composite cementitious material zinokumelana namanzi okuhle kakhulu. Uma izinto ze-titanium gypsum fly ash slag composite cementitious material zingaxutshwa ne-activator, isikhathi sazo sokusetha side futhi amandla azo okuqala aphansi. Ukwengeza inani elifanele lesimende kule nto ehlanganisiwe yokuqinisa ubumba kunganciphisa isikhathi sokusetha kwezinto ezihlanganisiwe zokuqinisa ubumba, okusiza ekukhuleni kwamandla ezinto ezihlanganisiwe zokuqinisa ubumba.

Eminye imiphumela yocwaningo ikhombisa ukuthi ukwengeza usimende ongu-5% ezintweni zokwakha ubumba ezihlanganisiwe ze-titanium gypsum fly ash slag kungafinyeza isikhathi sokuqala sokusetha izinto zokwakha ubumba ezihlanganisiwe sibe ngamahora angu-4, isikhathi sokugcina sokusetha sibe ngamahora angu-9, kanti amandla okuguquguquka angu-28d kanye namandla okucindezela kungafinyelela ku-5.8MPa kanye no-29.OMPa ngokulandelana. Izinto zokwakha ubumba ezihlanganisiwe ezisebenza kahle kakhulu zingalungiswa ngokusebenzisa i-titanium gypsum, umlotha okhuphukayo, i-slag kanye nenani elincane le-Portland cement noma i-clinker, ukukhetha i-activator efanele kanye nokuthatha izinyathelo ezifanele zenqubo. Ucwaningo lukhombisa ukuthi ukwengeza i-alunite engu-5% ezintweni zokwakha ubumba ezihlanganisiwe ze-titanium gypsum fly ash slag kungafinyeza isikhathi sokuqala sokusetha izinto zokwakha ubumba ezihlanganisiwe sibe yihora eli-1, isikhathi sokugcina sokusetha sibe ngamahora angu-2, kanti amandla okuguquguquka angu-28d kanye namandla okucindezela afinyelela ku-9.5 MPa kanye no-53.0 MPa ngokulandelana, afinyelela izinga lamandla le-525R slag Portland cement.

3. Izinhlobo ezahlukene zama-activator zithinta kanjani amandla ezinto zokwakha ze-titanium gypsum ezihlanganisiwe?

Amandla ezinto ezihlanganisiwe eziqinisa ubumba angathuthukiswa kakhulu ngemva kokuncishiswa kwe-titanium gypsum. Amandla angu-28d ezinto ezihlanganisiwe eziqinisa ubumba ezivuselelwa yi-simende yodwa anda ngo-70%, kanti amandla okugoba nokucindezela ezinto ezihlanganisiwe eziqinisa ubumba anda ngokwanda kokuqukethwe kwe-simende. Lapho okuqukethwe kwe-simende kungu-15%, amandla ayo aphezulu kakhulu. Lapho okuqukethwe kwe-lime kungu-15%, okuqukethwe kwe-simende kungu-0, kanti amandla ayo aphansi kakhulu. Kuhlelo lwe-titanium gypsum fly ash olune-calcined, ukusetshenziswa kwe-simende evuselelayo kusiza kakhulu ekuthuthukiseni amandla esistimu.
