Inombolo yeCAS: 68855-54-9 (umgubo oxutyiweyo we-calcium)
Ukusetyenziswa: Isetyenziswa kwishishini lokwenza ubhiya, ishishini leziselo, ishishini lamayeza, ukucocwa, ukucocwa kweswekile, kunye neshishini leekhemikhali.
Ukwakheka kweekhemikhali
Ulwakhiwo lweekhemikhali zomhlaba we-diatomaceous luyi-amorphous SiO2 ikakhulu2, ekhoyo ngohlobo lweSiO2• i-nH2O. SiO2idla ngokuba ngaphezu kwama-80%, ukuya kuthi ga kuma-94%. Iqulethe izixa ezincinci ze-Al2O3, Fe2O3, CaO, MgO, K2Kwi2O, P2O5, kunye nezinto eziphilayo, kunye nezinye izinto ezingcolisayo zesinyithi ezifana neCr kunye neBa. Ukwakheka kunye nomxholo weemigodi zomhlaba ze-diatomaceous ziyahluka kwiindawo ezahlukeneyo.
Iipropati Zomzimba
I-Diatomaceous earth inemibala efana nomhlophe, ongwevu omhlophe, ongwevu, ongwevu okhanyayo, ongwevu okhanyayo, otyheli okhanyayo, njl.njl. Ubuninzi: 1.9~2.3g/cm3；Ubuninzi bobuninzi 0.34~0.65g/cm3; Indawo yokunyibilika: 1650 ℃ ~ 1750 ℃; Ummandla othile womphezulu we-19-65cm2/g; Umthamo wembobo 0.45~0.98cm3/g; Izinga lokufunxwa kwamanzi liphindwe kabini ukuya kane kunomthamo walo. Uzinzo oluphezulu lweekhemikhali, alunyibiliki kwi-hydrochloric acid, lunyibilika lula kwi-alkali, luneempawu ezininzi ezintle ezifana nokungaxinani, ukuthamba, ukuthintela isandi, ukumelana nokuguguleka, kunye nokumelana nobushushu.
Uphuhliso kunye nokusetyenziswa
I-diatomaceous earth, ngenxa yeempawu zayo ezikhethekileyo ze-physicochemical, isetyenziswa kakhulu njengesincedisi sesihluzo, isizalisi esisebenzayo, isithwali se-catalyst, isithwali sezinambuzane kunye nesichumisi, izinto zokukhusela, izinto zokungenisa umoya, kunye nezinto zokufiphaza.
Uncedo lokucoca:
I-Diatomaceous earth ingasetyenziswa njengesihluzo esiluncedo kumashishini okutya, amayeza, kunye nokusingqongileyo. Umzekelo, ukusetyenziswa kwe-diatomaceous earth filtration kwinkqubo yokwenza iwayini kunokuhlaziya rhoqo indawo yokucoca, isantya sokucoca esikhawulezayo, isivuno esikhulu; Ngomphezulu omkhulu kunye namandla okufunxa aqinileyo, inokucoca amasuntswana ukusuka kwi-0.1 ukuya kwi-1.0 μ m, inciphise ukulahleka kotywala malunga ne-1.4%, kwaye iphucule iimeko zokusebenza kwemveliso. Izihluzo zomhlaba ze-Diatomaceous zinokuphucula ngcono umgangatho wamanzi echibini lokudada elijikeleza amanzi, kwaye zingonga amanzi kunye nombane ekusebenzeni nasekulawuleni amachibi okudada. Okwesibini, i-diatomaceous earth ikwasetyenziswa kakhulu kwiioyile ezityiwayo, ulwelo lomlomo lwamayeza, nakwezinye iindawo.
I-Adsorbent：
I-Diatomaceous earth isetyenziswa kakhulu ekunyangweni kwamanzi amdaka ngenxa yeempawu zayo ezizinzileyo zeekhemikhali, amandla ayo okufunxa amanzi, ukusebenza kakuhle kokucoca kunye nokunganyibiliki kuyo nayiphi na i-asidi enamandla. Unyango lwangaphambi kokulungiswa kwe-leachate yokulahlwa kwenkunkuma kusetyenziswa indlela ye-diatomaceous earth flocculation precipitation lunokunciphisa i-CODCr kunye ne-BOD5 kwi-leachate, lususe ungcoliseko olufana ne-SS, kwaye lusetyenziswa kakhulu kumanzi amdaka asezidolophini, ukwenza amaphepha, ukuprinta nokudaya amanzi amdaka, ukubulala amanzi amdaka, amanzi amdaka aneoyile, kunye namanzi amdaka esinyithi esinzima.
