Titaniyamu gypsum ndi mtundu wa zinyalala zotsalira ndi dihydrate gypsum monga chigawo chachikulu, amene amapangidwa ndi kuwonjezera laimu (kapena kashiamu carbonate) neutralize kuchuluka kwa asidi madzi oipa kuti kuchitira asidi madzi oipa pamene titaniyamu woipa amapangidwa ndi njira sulfuric acid. .Kutulutsidwa kwa titaniyamu gypsum sikungotenga malo ambiri ndikuipitsa chilengedwe, komanso kumayambitsa mavuto azachuma kwa mabizinesi a titaniyamu.Titaniyamu gypsum angagwiritsidwe ntchito kupanga simenti retarder pambuyo kukonzedwa ndi makina akupera.Guilin Hongcheng ndi katswiri wopangatitaniyamumphero ya gypsum.Zotsatirazi zikufotokozera momwe mungakonzekerere zida za simenti za titaniyamu gypsum ndikuchita bwino.

1. Kodi zotsatira za kuwonjezera zosakaniza zosiyanasiyana mu titaniyamu gypsum ndi chiyani?

Mphamvu ya titaniyamu gypsum pambuyo posinthidwa thupi imakhala ndi kusiyana kwina ndi gypsum yachilengedwe ndi gypsum yamankhwala ena.Zina zowonjezera ziyenera kuwonjezeredwa kuti ziwonjezere mphamvu za titaniyamu gypsum.Zowonjezera zomwe zimagwiritsidwa ntchito zimaphatikizapo phulusa la desulfurization, phulusa la ntchentche, slag yozimitsidwa ndi madzi, alum, chochepetsera madzi ndi retarder.

Pamene madzi kuzimitsidwa slag ntchito ngati kuwala akaphatikiza, pamene zili zosakwana 40%, izo sizidzakhudza mphamvu ya titaniyamu gypsum mankhwala, ndipo akhoza kuchepetsa kachulukidwe chochuluka cha mankhwala;Pamene zili ntchentche phulusa ndi zosakwana 30%, ali ndi zotsatira pang'ono pa kuwongolera mphamvu titaniyamu gypsum, koma pamene zili ntchentche phulusa ndi oposa 30%, izo kuchepetsa mphamvu ya titaniyamu gypsum, ndi ntchentche phulusa. ndizothandiza kukonza mochedwa mphamvu ya titaniyamu gypsum (7d).Phulusa la desulfurized limatha kusintha kwambiri mphamvu ya titaniyamu gypsum.Ndi kuchuluka kwa zomwe zili, mphamvu za titaniyamu gypsum zitha kusintha kwambiri.Alum akhoza kusintha mphamvu ya titaniyamu gypsum, ndipo pamene zili 3%, zotsatira zake ndi zabwino kwambiri;Kuchuluka kwa madzi owonjezera kumakhala ndi zotsatira zoonekeratu pa mphamvu ya titaniyamu gypsum.Ndi kuwonjezeka kwa madzi owonjezera, mphamvu ya chitsanzo imachepa kwambiri.Choncho, poonetsetsa kuti madzi a gypsum phala amadzimadzimadzi, kuchepetsa kuchuluka kwa madzi owonjezera, ndibwino.

Monga kuphatikizika kopepuka, slag yozimitsidwa ndi madzi imatha kupititsa patsogolo kuchuluka kwazinthu zoyeserera za titaniyamu gypsum.Phulusa la desulfurized, phulusa la ntchentche ndi alum zimatha kusintha kwambiri mphamvu ya titaniyamu gypsum.Choncho, titaniyamu gypsum, phulusa desulfurized ndi ntchentche phulusa amasankhidwa monga ufa, madzi kuzimitsidwa slag ntchito monga kuunikira aggregate, ndi alum, melamine ndi citric asidi ntchito monga zowonjezera.Magawo abwino kwambiri amapezeka posintha gawo la ufa.Gawo la aggregate ndi 40% ya ufa, gawo la alum mu zowonjezera ndi 3% ya ufa, gawo la melamine ndi citric acid ndi 1% motsatana, ndi kuwonjezera kwa titaniyamu gypsum 70% ndi phulusa la desulfurized 30% , ntchito ya simenti ndi yabwino.

2. Kodi mungakonzekere bwanji titaniyamu gypsum composite cementitious material ndi ntchito yabwino?

Pambuyo pa calcining kwa 2h pa 600 ℃, titaniyamu gypsum imaphatikizidwa ndi ntchentche phulusa, slag ndi simenti kufupikitsa nthawi yoyambira yamagulu mpaka 3h, nthawi yomaliza yokhazikika mpaka 5h, ndi 28d flexural mphamvu ndi compressive mphamvu zimafika 4.3MPa ndi 13.6MPa motero.Ndi titaniyamu gypsum ndi slag monga zigawo zikuluzikulu, simenti clinker ndi kompositi oyambirira mphamvu zochepetsera madzi angagwiritsidwe ntchito kukonzekera simenti ndi ntchito bwino, ndipo mphamvu zake ndi madzi kukana mwachionekere apamwamba kuposa kumanga gypsum.Kafukufukuyu akuwonetsa kuti mphamvu ya titaniyamu gypsum wosakanikirana ndi simenti pambuyo pochiritsa kwachilengedwe kwa masiku 28 amatha kukwaniritsa zofunikira za zida zomangira khoma ndi zida zosakanikirana zamatauni, kusungunuka kwake ndi zosakwana 20% za gypsum yomanga, komanso mayamwidwe ake amadzi. ndi pafupifupi 50% ya gypsum yomanga, zomwe zikuwonetsa kuti titaniyamu gypsum composite cementitious material ili ndi mphamvu yokana madzi.Ngati titaniyamu gypsum fly ash slag composite cementitious material sinasakanizidwe ndi activator, nthawi yake yokhazikitsira ndi yaitali ndipo mphamvu zake zoyambirira zimakhala zochepa.Kuonjezera kuchuluka kwa simenti kuzinthu zophatikizika za simentiyi mwachiwonekere kungafupikitse nthawi yokhazikitsira zinthu zophatikizika za simenti, zomwe zimathandizira kukula kwa mphamvu ya zinthu zophatikizika za simenti.

Zotsatira zina za kafukufuku zikuwonetsa kuti kuwonjezera 5% simenti ku titaniyamu gypsum fly ash slag composite cementitious zakuthupi kumatha kufupikitsa nthawi yoyambira ya simenti yophatikizika kukhala 4h, nthawi yomaliza yoyika mpaka 9h, ndi 28d flexural mphamvu ndi mphamvu zopanikiza zimatha kufikira. 5.8MPa ndi 29.OMa motsatana.Zida zopangira simenti zapamwamba zitha kukonzedwa pogwiritsa ntchito titaniyamu gypsum, phulusa la ntchentche, slag ndi simenti yaing'ono ya Portland kapena clinker, kusankha choyambitsa choyenera ndikutengera njira zoyenera.Kafukufukuyu akusonyeza kuti kuwonjezera 5% alunite mu titaniyamu gypsum ntchentche phulusa slag gulu cementitious zakuthupi akhoza kufupikitsa nthawi yoika koyamba kwa gulu cementitious zakuthupi 1h, yomaliza yoika nthawi 2h, ndi 28d flexural mphamvu ndi compressive mphamvu kufika 9.5 MPa ndi 53.0 MPa motero, kufika muyezo mphamvu 525R slag Portland simenti.

3. Kodi zoyatsira zamitundu yosiyanasiyana zimakhudza bwanji kulimba kwa zida za simenti za titaniyamu gypsum?

Mphamvu ya gulu cementitious zakuthupi akhoza kwambiri bwino pambuyo calcination wa titaniyamu gypsum.Mphamvu ya 28d ya zinthu zophatikizika za simenti zomwe zimasangalatsidwa ndi simenti yokha zidakwera ndi 70%, ndipo mphamvu yosunthika komanso yophatikizika yazinthu zophatikizika za simenti zidawonjezeka ndi kuchuluka kwa simenti.Pamene simenti ili ndi 15%, mphamvu zake zimakhala zapamwamba kwambiri.Pamene laimu ali ndi 15%, simenti ili ndi 0, ndipo mphamvu yake imakhala yotsika kwambiri.Mu calcined titaniyamu gypsum ntchentche phulusa dongosolo, ntchito kukokera simenti ndi bwino kupititsa patsogolo mphamvu ya dongosolo.
