I-Diatomaceous Earth, evame ukubizwa ngokuthi ufulawa wentaba, i-fossil powder noma i-radiolaria powder, iyidwala le-biogenic siliceous sedimentary, elakhiwe ikakhulukazi izinsalela ze-siliceous zama-diatom nezinye izinto ezincane eziphilayo. Kunezinguqulo eziningi zesiNgisi, ezivela emaphephandabeni nasezindaweni ezithile: Tripoli, Tripolite, TripoliEarth, Tripoli-Powder, Diatomite.
I-Diatomite iyidwala elithambile elinombala okhanyayo elakhiwe ikakhulukazi izinsalela zamathambo e-siliceous of diatoms. Idwala elinezimbotshana ezinobukhulu bezinhlayiyana ezincane kanye namandla adonsela phansi athile aphansi. Lezi zakhiwo ziyenza isebenziseke njengesihlungi semidiya, into emuncayo, nanjengesigcwalisi esingasindi senjoloba, upende, namapulasitiki. Uma i-diatomite ichotshozwa ibe yimpushana, ngokuvamile ibizwa ngokuthi "i-diatomaceous earth," noma i-DE Diatomite Ithathwe ezinsalela zolwandle olusanhlamvu oluncane oluncane noma ulwelwe lwamanzi ahlanzekile, i-diatomite iyiminerali eyenzeka ngokwemvelo, eguquguqukayo esetshenziswa ezinhlotsheni eziningi zezicelo ezivela kuzimonyo ukuya ekuhlungeni. .
Ingxenye yamakhemikhali eyinhloko yomhlaba we-diatomaceous yi-silicate. Okuqukethwe kwe-SiO2 kungenye yezinkomba zokuqukethwe kwe-diatom ku-diatomite ore, futhi i-SiO2 ephezulu ingeyekhwalithi enhle. I-Diatomaceous Earth iqukethe amanzi angu-1% ~ 5%, futhi izinga lokushisa lokulahlekelwa kwamanzi emanzini angama-colloidal lingu-110 ~ 250 °C.
Ukusetshenziswa kwe-Diatomite kanye ne-Diatomaceous Earth
I-Diatomite ivame ukusetshenziswa njengesengezo lapho kwenziwa usimende we-portland. I-diatomite yekhwalithi ephezulu iqukethe i-silica engaphezu kuka-80%, futhi yengezwa enqubweni yokwenza usimende ukuze kuthuthukiswe okuqukethwe kwe-silica komkhiqizo. I-Diatomite eqondile esuka emayini iyachotshozwa futhi ihlanganiswe ne-limestone, i-shale, noma ezinye izinto ezisetshenziselwa ukwenza usimende.
Ukusetshenziswa okune okuyinhloko kwe-diatomite e-United States phakathi no-2017 kwakuyi-filtration (50%), i-aggregate yokukhanya (30%), i-fillers (15%), kanye ne-absorbents (5%). Izici ze-diatomite ezenza kube usizo kulezi zinhlelo zokusebenza zibalwe ngezansi.
- Usayizi wezinhlayiyana ezincane
- I-porosity ephezulu
- Indawo ephezulu
- Ukwakheka kwe-siliceous okungenzi lutho
- Amandla adonsela phansi athile
