I-Titanium gypsum luhlobo lwenkunkuma eseleyo ene-dihydrate gypsum njengeyona nto iphambili, eveliswa ngokongeza ilayimu (okanye i-calcium carbonate) ukuze kuncitshiswe amanzi amaninzi amdaka e-asidi ukuze kunyangwe amanzi amdaka e-asidi xa i-titanium dioxide iveliswa ngendlela ye-sulfuric acid. Ukukhutshwa kwe-titanium gypsum akugcini nje ngokuthatha umhlaba omninzi kwaye kungcolise okusingqongileyo, kodwa kukwabangela umthwalo omkhulu kwezoqoqosho kumashishini e-titanium dioxide. I-Titanium gypsum ingasetyenziselwa ukwenza i-samente retarder emva kokuba isetyenzisiwe ngomatshini wokusila. UGuilin Hongcheng ngumvelisi ochwephesha weititaniumumatshini wokugaya i-gypsum.Oku kulandelayo kuchaza indlela yokulungisa izinto ze-titanium gypsum composite cementitious materials ezisebenza kakuhle.

1. Yintoni impembelelo yokongeza izinto ezahlukeneyo kwi-titanium gypsum ekusebenzeni kwayo?

Ipropati yamandla e-titanium gypsum emva kokuguqulwa ngokomzimba inesithuba esithile kunye neye-gypsum yendalo kunye nezinye iikhemikhali ze-gypsum. Ezinye izongezo kufuneka zongezwe ukuphucula ipropati yamandla e-titanium gypsum. Izongezo ezisetyenzisiweyo ziquka uthuthu olunyibilikisa i-sulfurization, uthuthu oluphaphazelayo, i-water quenched slag, i-alum, i-water reducer kunye ne-retarder.

Xa i-slag ecinyiweyo ngamanzi isetyenziswa njenge-aggregate ekhanyayo, xa umxholo ungaphantsi kwama-40%, ayizukuchaphazela amandla emveliso ye-titanium gypsum, kwaye inokunciphisa ngokufanelekileyo uxinano olukhulu lwemveliso; Xa umxholo we-fly ash ungaphantsi kwama-30%, inefuthe elincinci ekuphuculeni amandla e-titanium gypsum, kodwa xa umxholo we-fly ash ungaphezulu kwama-30%, iya kunciphisa amandla e-titanium gypsum, kwaye i-fly ash iluncedo ekuphuculeni amandla asemva kwe-titanium gypsum (7d). I-desulfurized ash inokuphucula kakhulu amandla e-titanium gypsum. Ngokwanda komxholo wayo, amandla eemveliso ze-titanium gypsum anokuphuculwa kakhulu. I-Alum inokuphucula ngokufanelekileyo amandla e-titanium gypsum, kwaye xa umxholo uyi-3%, umphumo uba ngcono; Ubungakanani bamanzi ongezelelweyo bunefuthe elicacileyo kumandla e-titanium gypsum. Ngokwanda kobungakanani bamanzi ongezelelweyo, amandla esampuli ancipha kakhulu. Ke ngoko, ngelixa kuqinisekiswa ukunyibilika kwe-gypsum paste, okukhona inani lamanzi ongezelelweyo liphantsi, kokukhona kungcono.

Njenge-aggregate ekhaphukhaphu, i-slag ecinyiweyo ngamanzi inokuphucula uxinano olukhulu lweemveliso ze-titanium gypsum trial. Uthuthu olunyibilikisiweyo, uthuthu oluphaphazelayo kunye ne-alum zinokuphucula kakhulu ukusebenza kwamandla kwe-titanium gypsum. Ke ngoko, i-titanium gypsum, uthuthu olunyibilikisiweyo kunye nothuthu oluphaphazelayo zikhethwa njengomgubo, i-slag enyibilikisiweyo ngamanzi isetyenziswa njengomxube wokukhanya, kwaye i-alum, i-melamine kunye ne-citric acid zisetyenziswa njengezongezo. Ezona parameter zibalaseleyo zifunyanwa ngokutshintsha umlinganiselo womgubo. Umlinganiselo we-aggregate yi-40% yomgubo, umlinganiselo we-alum kwisongezelelo yi-3% yomgubo, umlinganiselo we-melamine kunye ne-citric acid yi-1% ngokulandelelana, kwaye ukongezwa kwe-titanium gypsum yi-70% kunye nothuthu olunyibilikisiweyo yi-30%, ukusebenza kwezinto ezisimende kulungile.

2. Ungayilungisa njani i-titanium gypsum composite cementitious material esebenza kakuhle?

Emva kokuba i-calcined kangangeeyure ezi-2 kwi-600℃, i-titanium gypsum idityaniswa ne-fly ash, i-slag kunye nesamente ukuze kufinyezwe ixesha lokuqala lokuseta le-composite ukuya kwi-3h, ixesha lokugqibela lokuseta libe yi-5h, kwaye amandla e-flexural angama-28d kunye namandla okucinezela afikelela kwi-4.3MPa kunye ne-13.6MPa ngokwahlukeneyo. Nge-titanium gypsum kunye ne-slag njengezinto ezisisiseko, i-cement clinker kunye ne-composite early strength water reducer zingasetyenziselwa ukulungiselela isamente ngokusebenza kakuhle, kwaye amandla ayo kunye nokumelana namanzi ngokucacileyo kungaphezulu kunokwakha i-gypsum. Uphando lubonisa ukuba amandla e-titanium gypsum mixed cementitious material emva kokunyibilika kwendalo kangangeentsuku ezingama-28 anokuhlangabezana neemfuno zezinto zokwakha udonga kunye nezinto ezixutyiweyo zendlela kamasipala, izinga layo lokunyibilika lingaphantsi kwe-20% ye-building gypsum, kwaye izinga layo lokufunxa amanzi limalunga ne-50% ye-building gypsum, okubonisa ukuba izinto ze-titanium gypsum composite cementitious material zinokumelana namanzi okuhle kakhulu. Ukuba izinto ze-titanium gypsum fly ash slag composite cementitious material azixutywanga ne-activator, ixesha lazo lokuseta lide kwaye amandla azo okuqala aphantsi. Ukongeza ubungakanani obufanelekileyo besamente kule nto idityanisiweyo yesamente kunokulinciphisa ixesha lokuseta le nto idityanisiweyo yesamente, nto leyo enceda ekukhuleni kwamandla ezinto ezidityanisiweyo zesamente.

Ezinye iziphumo zophando zibonisa ukuba ukongeza i-5% yesamente kwizinto ezidityanisiweyo ze-titanium gypsum fly ash slag kunganciphisa ixesha lokuqala lokuseta izinto ezidityanisiweyo ukuya kwiiyure ezi-4, ixesha lokugqibela lokuseta ukuya kwiiyure ezi-9, kwaye amandla e-flexural angama-28d kunye namandla okucinezela angafikelela kwi-5.8MPa kunye ne-29.OMPa ngokwahlukeneyo. Izinto ezidityanisiweyo ezisebenzayo kakhulu zingalungiswa ngokusebenzisa i-titanium gypsum, i-fly ash, i-slag kunye nenani elincinci lesamente yasePortland okanye i-clinker, ukukhetha i-activator efanelekileyo kunye nokuthatha amanyathelo afanelekileyo enkqubo. Uphando lubonisa ukuba ukongeza i-5% ye-alunite kwizinto ezidityanisiweyo ze-titanium gypsum fly ash slag kunganciphisa ixesha lokuqala lokuseta izinto ezidityanisiweyo ukuya kwiyure eli-1, ixesha lokugqibela lokuseta ukuya kwiiyure ezi-2, kwaye amandla e-flexural angama-28d kunye namandla okucinezela afikelela kwi-9.5 MPa kunye ne-53.0 MPa ngokwahlukeneyo, ukufikelela kumgangatho wamandla wesamente yasePortland engama-525R slag.

3. Iintlobo ezahlukeneyo zezinto ezivuselelayo zichaphazela njani amandla ezinto zesamente ezidityanisiweyo ze-titanium gypsum?

Amandla ezinto ezidityanisiweyo zesamente anokuphuculwa kakhulu emva kokuba i-titanium gypsum inyibilikisiwe. Amandla angama-28d ezinto ezidityanisiweyo zesamente ezivuselelwa yisamente yodwa anyuke nge-70%, kwaye amandla okugoba kunye nokucinezela ezinto ezidityanisiweyo zesamente anyuke ngokwanda komxholo wesamente. Xa umxholo wesamente uyi-15%, amandla ayo aphezulu. Xa umxholo welayimu uyi-15%, umxholo wesamente uyi-0, kwaye amandla ayo aphantsi. Kwinkqubo ye-titanium gypsum fly ash ene-calcined, ukusetyenziswa kwesamente evuselelayo kunceda ngakumbi ekuphuculeni amandla enkqubo.
