I-Titanium gypsum luhlobo lwentsalela yenkunkuma ene-dihydrate gypsum njengenxalenye ephambili, eveliswa ngokugalela ikalika (okanye i-calcium carbonate) ukuze ithobe isixa esikhulu samanzi amdaka e-asidi ukuze kunyangwe amanzi amdaka e-asidi xa i-titanium dioxide iveliswa yindlela ye-sulfuric acid. .Ukukhutshwa kwe-titanium gypsum akuhlali nje kuphela kumhlaba omninzi kwaye kungcolise indalo, kodwa kubangela umthwalo omkhulu wezoqoqosho kumashishini e-titanium dioxide.I-Titanium gypsum ingasetyenziselwa ukwenza iretarder yesamente emva kokuba isetyenzwe ngomatshini wokusila.UGuilin Hongcheng ngumvelisi oqeqeshiweyo wetitaniumilitye lokusila igypsum.Oku kulandelayo kuchaza indlela yokulungiselela i-titanium gypsum composite imathiriyeli yesamente kunye nokusebenza kakuhle.

1. Yintoni umphumo wokongezwa kwee-admixtures ezahlukeneyo kwi-titanium gypsum ekusebenzeni kwayo?

Ipropathi yamandla ye-titanium gypsum emva kokuguqulwa komzimba ine-gap ethile kunye ne-gypsum yendalo kunye nezinye iikhemikhali zegypsum.Ezinye izongezo kufuneka zongezwe ukuphucula amandla epropathi ye-titanium gypsum.Izongezo ezisetyenzisiweyo ziquka i-desulfurization ash, i-fly ash, i-water quenched slag, i-alum, isinciphisi samanzi kunye ne-retarder.

Xa i-slag yokucima amanzi isetyenziswe njenge-aggregate yokukhanya, xa umxholo ungaphantsi kwe-40%, awuyi kuchaphazela amandla emveliso ye-titanium gypsum, kwaye inokunciphisa ngokufanelekileyo ubuninzi bemveliso;Xa umxholo impukane uthuthu ngaphantsi kwama-30%, inefuthe elincinane ekuphuculeni amandla titanium gypsum, kodwa xa umxholo fly uthuthu ngaphezu 30%, oko kuya kunciphisa amandla titanium gypsum, kwaye fly uthuthu. luncedo ekuphuculeni amandla kade kwe-titanium gypsum (7d).Uthuthu lwe-desulfurized lunokuphucula kakhulu amandla e-titanium gypsum.Ngokunyuka komxholo wayo, amandla emveliso ye-titanium gypsum inokuphuculwa kakhulu.I-Alum inokuphucula ngokufanelekileyo amandla e-titanium gypsum, kwaye xa umxholo u-3%, umphumo ungcono kakhulu;Ubungakanani bamanzi abongeziweyo bunempembelelo ecacileyo kumandla we-titanium gypsum.Ngokunyuka komthamo wamanzi ongeziweyo, amandla esampuli ayancipha kakhulu.Ke ngoko, ngelixa uqinisekisa ubumanzi be-gypsum paste, ukuthoba umthamo wamanzi ongeziweyo, kungcono.

Njengomdibaniso wokukhanya, i-slag ecinyiweyo yamanzi inokuphucula ukuxinana kweemveliso zolingo lwe-titanium gypsum.Uthuthu lwe-desulfurized, i-fly ash kunye ne-alum inokuphucula kakhulu ukusebenza kwamandla e-titanium gypsum.Ngoko ke, i-titanium gypsum, i-desulfurized ash kunye ne-fly ash zikhethwa njengomgubo, i-slag ecinyiweyo yamanzi isetyenziswa njenge-aggregate yokukhanya, kwaye i-alum, i-melamine kunye ne-citric acid isetyenziswa njengezongezo.Iiparamitha ezilungileyo kakhulu zifunyenwe ngokutshintsha umlinganiselo we powder.Umlinganiselo we-aggregate yi-40% yomgubo, umlinganiselo we-alum kwi-additive yi-3% yomgubo, umlinganiselo we-melamine kunye ne-citric acid yi-1% ngokulandelanayo, kunye nokongezwa kwe-titanium gypsum 70% kunye nothuthu lwe-desulfurized 30% , ukusebenza kwezinto zesamente kulungile.

2. Ukulungiselela njani i-titanium gypsum composite cementitious material kunye nokusebenza kakuhle?

Emva kokuba i-calcining ye-2h kwi-600 ℃, i-titanium gypsum idityaniswe ne-fly ash, i-slag kunye ne-samente ukunciphisa ixesha lokuqala lokumisela le-composite ukuya kwi-3h, ixesha lokugqibela lokumisela ukuya kwi-5h, kunye ne-28d amandla okuguquguquka kunye namandla oxinzelelo afikelela kwi-4.3MPa kunye 13.6MPa ngokulandelelanayo.Nge-titanium gypsum kunye ne-slag njengamacandelo asisiseko, i-cement clinker kunye ne-composite yokuqala yokunciphisa amanzi ingasetyenziselwa ukulungiselela i-samente ngokusebenza okugqwesileyo, kwaye amandla ayo kunye nokuchasana kwamanzi ngokucacileyo kuphezulu kunokwakhiwa kwe-gypsum.Uphando lubonisa ukuba amandla e-titanium gypsum exutywe ngezinto ze-cementitious emva kokunyanga kwendalo kwiintsuku ezingama-28 zinokuhlangabezana neemfuno zezixhobo zokwakha udonga kunye ne-subgrade yendlela kamasipala yezinto ezixubileyo, izinga layo lokuchithwa lingaphantsi kwe-20% ye-gypsum yokwakha, kunye nesantya sokufunxa amanzi. malunga ne-50% ye-gypsum yokwakha, ebonisa ukuba i-titanium gypsum composite imathiriyeli yesamente inokumelana okugqwesileyo kwamanzi.Ukuba i-titanium gypsum fly ash slag composite cementitious material ayixutywanga ne activator, ixesha layo lokumisela lide kwaye amandla ayo okuqala aphantsi.Ukongeza ubungakanani obufanelekileyo besamente kule mveliso yesamente ehlanganisiweyo ngokucacileyo kunokunciphisa ixesha lokumiselwa kwezinto ezidityanisiweyo zesamente, ezinceda ekukhuleni kwamandla ezinto ezidibeneyo zesamente.

Ezinye iziphumo zophando zibonisa ukuba ukongeza i-5% yesamente kwi-titanium gypsum fly ash ash slag composite cementitious material inokunciphisa ixesha lokuqala lokumisela izinto ezidibeneyo ze-cementitious ukuya kwi-4h, ixesha lokugqibela lokumisela ukuya kwi-9h, kunye ne-28d amandla okuguquguquka kunye namandla oxinzelelo anokufikelela. I-5.8MPa kunye ne-29.OMa ngokulandelelanayo.Izinto eziphezulu ze-cementitious composite zingalungiswa ngokusebenzisa i-titanium gypsum, i-fly ash, i-slag kunye nenani elincinci le-samente ye-Portland okanye i-clinker, ukukhetha i-activator efanelekileyo kunye nokuthatha amanyathelo afanelekileyo enkqubo.Uphando lubonisa ukuba ukongeza i-5% ye-alunite kwi-titanium gypsum fly ash ash slag composite cementitious material inokunciphisa ixesha lokuqala lokumisela izinto ezidibeneyo ze-cementitious ukuya kwi-1h, ixesha lokugqibela lokumisela ukuya kwi-2h, kunye ne-28d amandla okuguquguquka kunye namandla oxinzelelo afikelela kwi-9.5 MPa kunye ne-53.0 MPa ngokulandelanayo, ukufikelela kumlinganiselo wamandla we-525R slag Portland sement.

3. Iindidi ezahlukeneyo zezivuseleli ziwachaphazela njani amandla e-titanium gypsum composite imathiriyeli yesamente?

Amandla ezinto ezihlanganisiweyo zesamente anokuphuculwa kakhulu emva kokubalwa kwe-titanium gypsum.Amandla e-28d yezinto ezidibeneyo ze-cementitious ezivuyiswa yi-samente yodwa ziye zanda nge-70%, kwaye amandla okuguquguquka kunye nokunyanzeliswa kwezinto ezidibeneyo zesamente zanda ngokunyuka kwesiqulatho sesamente.Xa isiqulatho sesamente siyi-15%, amandla ayo aphezulu.Xa umxholo we-lime u-15%, umxholo we-samente ngu-0, kwaye amandla ayo aphantsi.Kwi-calcined titanium gypsum fly ash system, ukusetyenziswa kwe-cement excitation kulungeleka ngakumbi ekuphuculeni amandla enkqubo.
