I-Titanium gypsum iwuhlobo lwezinsalela zemfucuza ene-dihydrate gypsum njengengxenye eyinhloko, ekhiqizwa ngokungeza i-lime (noma i-calcium carbonate) ukuze kuncishiswe inani elikhulu lamanzi angcolile ane-asidi ukuze kusetshenziswe amanzi angcolile ane-asidi lapho i-titanium dioxide ikhiqizwa ngendlela ye-sulfuric acid. .Ukukhishwa kwe-titanium gypsum akugcini nje ngokuthatha umhlaba omningi futhi kungcolisa imvelo, kodwa futhi kubangela umthwalo omkhulu wezomnotho emabhizinisini e-titanium dioxide.I-Titanium gypsum ingasetshenziselwa ukwenza i-retarder kasimende ngemva kokucutshungulwa ngomshini wokugaya.UGuilin Hongcheng ungumkhiqizi ochwepheshe wetitaniumumshini wokugaya i-gypsum.Okulandelayo kuchaza indlela yokulungisa izinto zikasimende eziyinhlanganisela ye-titanium gypsum ngokusebenza kahle.

1. Uyini umphumela wokwengeza ama-admixtures ahlukahlukene ku-titanium gypsum ekusebenzeni kwayo?

Impahla yamandla ye-titanium gypsum ngemva kokuguqulwa komzimba inegebe elithile nalelo le-gypsum yemvelo kanye namanye amakhemikhali e-gypsum.Ezinye izithasiselo kumele zengezwe ukuze kuthuthukiswe impahla yamandla ye-titanium gypsum.Izithasiselo ezisetshenzisiwe zifaka umlotha we-desulfurization, umlotha wempukane, i-slag ecishiwe amanzi, i-alum, isinciphisi samanzi kanye ne-retarder.

Lapho i-slag ecishiwe amanzi isetshenziswa njenge-aggregate yokukhanya, lapho okuqukethwe kungaphansi kuka-40%, ngeke kuthinte amandla omkhiqizo we-titanium gypsum, futhi kunganciphisa ngokuphumelelayo ukuminyana kobuningi bomkhiqizo;Lapho okuqukethwe kwe-fly ash kungaphansi kuka-30%, kunomphumela omncane ekuthuthukiseni amandla e-titanium gypsum, kodwa lapho okuqukethwe komlotha wempukane kungaphezu kuka-30%, kuzonciphisa amandla e-titanium gypsum, kanye nomlotha wendiza. kuyasiza ukuthuthukisa amandla asekupheleni kwe-titanium gypsum (7d).Umlotha we-desulfurized ungathuthukisa kakhulu amandla we-titanium gypsum.Ngokukhula kokuqukethwe kwayo, amandla emikhiqizo ye-titanium gypsum angathuthukiswa kakhulu.I-Alum ingathuthukisa ngempumelelo amandla e-titanium gypsum, futhi lapho okuqukethwe kungu-3%, umphumela ungcono kakhulu;Inani lamanzi elengeziwe linomphumela osobala emandleni e-titanium gypsum.Ngokukhula kwenani lamanzi angeziwe, amandla esampula ayancipha kakhulu.Ngakho-ke, ngenkathi uqinisekisa uketshezi lwe-gypsum paste, ukwehla kwenani lamanzi angeziwe, kungcono.

Njengokuhlanganiswa okukhanyayo, i-slag ecishiwe amanzi ingathuthukisa ukuminyana kwenqwaba yemikhiqizo yesilingo se-titanium gypsum.Umlotha osuphelile, umlotha wempukane kanye ne-alum kungathuthukisa kakhulu ukusebenza kwamandla kwe-titanium gypsum.Ngakho-ke, i-titanium gypsum, umlotha we-desulfurized kanye nomlotha wempukane kukhethwa njenge-powder, i-slag ecishiwe amanzi isetshenziswa njenge-aggregate yokukhanya, futhi i-alum, i-melamine ne-citric acid isetshenziswa njengezithasiselo.Imingcele engcono kakhulu itholakala ngokushintsha ingxenye yempushana.Ingxenye ye-aggregate ingu-40% we-powder, ingxenye ye-alum esengezo ingu-3% wempushana, ingxenye ye-melamine ne-citric acid ingu-1% ngokulandelana, kanye nokwengezwa kwe-titanium gypsum 70% nomlotha we-desulfurized 30% , ukusebenza kwe-cementitious material kuhle.

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

Ngemva kokubala i-2h ku-600 ℃, i-titanium gypsum ihlanganiswa nomlotha wempukane, i-slag kanye nosimende ukuze kufinyezwe isikhathi sokuqala sokusetha senhlanganisela sibe ngu-3h, isikhathi sokusetha sokugcina sibe ngu-5h, kanye namandla okuguquguquka angu-28d namandla okucindezela afinyelela ku-4.3MPa futhi 13.6MPa ngokulandelana.Nge-titanium gypsum kanye ne-slag njengezingxenye eziyisisekelo, i-cement clinker kanye ne-composite yamandla yokunciphisa amanzi okuqala ingasetshenziswa ukulungisa usimende ngokusebenza okuhle kakhulu, futhi amandla ayo nokumelana namanzi ngokusobala kuphakeme kunokwakha i-gypsum.Ucwaningo lukhombisa ukuthi amandla e-titanium gypsum exutshwe usimende ngemuva kokwelashwa kwemvelo izinsuku ezingama-28 angahlangabezana nezidingo zezinto zokwakha odongeni kanye nezinto ezixutshwe zomgwaqo kamasipala, izinga layo lokuhlakazeka lingaphansi kwama-20% we-gypsum yokwakha, kanye nezinga lokumuncwa kwamanzi. cishe u-50% we-gypsum yokwakha, okubonisa ukuthi i-titanium gypsum composite cementitious material inokumelana okuhle kwamanzi.Uma i-titanium gypsum fly ash slag composite cementitious material ingaxutshwa nesicuphi, isikhathi sayo sokumisa side futhi amandla ayo okuqala aphansi.Ukwengeza inani elifanele likasimende kule nhlanganisela yezinto zikasimende ngokusobala kunganciphisa isikhathi sokusetha sezinto ezihlanganisiwe zikasimende, okulungele ukukhula kwamandla ezinto ezihlanganisiwe zikasimende.

Eminye imiphumela yocwaningo ibonisa ukuthi ukwengeza usimende ongu-5% ku-titanium gypsum fly ash slag eyinhlanganisela yezinto zikasimende kunganciphisa isikhathi sokuqala sokusetha sezinto eziyinhlanganisela zikasimende sibe ngamahora ama-4, isikhathi sokusetha sokugcina sibe ngamahora angu-9, futhi amandla aguquguqukayo angu-28d namandla okucindezela angafinyelela. 5.8MPa kanye ne-29.OMa ngokulandelanayo.Izinto zokwakha zikasimende ezisebenza kahle kakhulu zingalungiswa kusetshenziswa i-titanium gypsum, umlotha wempukane, i-slag kanye nenani elincane le-Portland usimende noma i-clinker, ukukhetha i-activator efanele kanye nokuthatha izinyathelo ezifanele zenqubo.Ucwaningo lubonisa ukuthi ukwengeza u-5% we-alunite ku-titanium gypsum fly ash slag eyinhlanganisela yezinto zikasimende kunganciphisa isikhathi sokuqala sokusetha sezinto eziyinhlanganisela zikasimende sibe ngu-1h, isikhathi sokusetha sokugcina sibe yi-2h, futhi amandla aguquguqukayo angu-28d namandla acindezelayo afinyelele ku-9.5 MPa kanye no-53.0 MPa ngokulandelanayo, okufinyelela izinga lamandla lika-525R slag Portland usimende.

3. Izinhlobo ezahlukene zezicishazi ziwathinta kanjani amandla ezinto zikasimende eziyinhlanganisela ye-titanium gypsum?

Amandla we-composite cementitious material angathuthukiswa kakhulu ngemva kokubalwa kwe-titanium gypsum.Amandla we-28d wezinto ezihlanganisiwe zikasimende ezijatshuliswa usimende yedwa akhuphuke ngo-70%, futhi amandla aguquguqukayo nawokucindezela ezinto eziyinhlanganisela zikasimende anda ngokwanda kokuqukethwe usimende.Uma okuqukethwe usimende kungu-15%, amandla awo aphezulu kakhulu.Lapho okuqukethwe kwe-lime kungu-15%, okuqukethwe kukasimende kungu-0, futhi amandla awo aphansi kakhulu.Kuhlelo lwe-calcined titanium gypsum fly ash, ukusetshenziswa kwe-excitation kasimende kulungele ukuthuthukisa amandla esistimu.
