Diatomaceous pasi / Diatomaceous pasi sefa rubatsiro
CAS #: 61790-53-2 (calcined powder)
CAS #: 68855-54-9 (yakasanganiswa calcined poda)
Kushandiswa: Inoshandiswa muindasitiri yekubikira doro, indasitiri yezvinwiwa, indasitiri yemishonga, kunatsa, kuchenesa shuga, uye indasitiri yemakemikari.
Kemikari yakagadzirwa
Iyo kemikari yepasi diatomaceous inonyanya kuve amorphous SiO2, iyo iripo muchimiro cheSiO2• nH2O. SiO2kazhinji inodarika 80%, kusvika 94%. Iine zvishoma zveAl2O3, Fe2O3, CaO, MgO, K2O, Na2O, P2O5, uye organic matter, pamwe nekumwe kusvibiswa kwesimbi kwakadai seCr naBa. Kuumbwa uye zvirimo zvediatomaceous pasi migodhi zvinosiyana munzvimbo dzakasiyana.
Zvinhu Zvenyama
Diatomaceous pasi rine mavara akadai sechena, grey chena, grey, grey grey, grey brown, mwenje yero, nezvimwewo; Density: 1.9 ~ 2.3g/cm3;Kuwanda kwehuwandu 0.34~0.65g/cm3; Kunyungudika: 1650 ℃~1750 ℃; Yakananga nzvimbo ye19-65cm2/g; Pore vhoriyamu 0.45 ~ 0.98cm3/g; Muyero wekutora mvura ndeye 2-4 nguva yehuwandu hwayo. High chemical stability, insoluble in hydrochloric acid, inonyungudika zviri nyore mualkali, ine zvinhu zvakawanda zvakanaka zvakadai sehama incompressibility, softness, sound insulation, wear resistance, uye heat resistance.
Development uye Application
Diatomaceous pasi, nekuda kweiyo yakasarudzika physicochemical zvimiro, yakashandiswa zvakanyanya seyamuro yekusefa, inoshanda yekuzadza, inotakura inotakura, mishonga yekuuraya zvipembenene uye inotakura fetiraiza, insulation zvinhu, adsorbent, uye bleaching zvinhu.
Sefa rubatsiro:
Diatomaceous pasi inogona kushandiswa sesefa yekubatsira mune zvekudya, mishonga, uye maindasitiri ezvakatipoteredza. Semuyenzaniso, kushandiswa kwe diatomaceous earth filtration mukuita winemaking process inogona kuramba ichivandudza mubhedha wefilter, fast filtration speed, goho guru; Nenzvimbo yakakura yepamusoro uye yakasimba adsorption capacity, inogona kusefa kunze zvidimbu kubva 0.1 kusvika 1.0 μ m, kuderedza kurasikirwa nedoro neinenge 1.4%, uye kuvandudza kugadzirwa kwemaitiro ekushanda. Diatomaceous pasi mafirita anogona kuvandudza zvirinani kunaka kwemvura yekushambira inotenderera kurapwa kwemvura, uye inogona kuchengetedza mvura nemagetsi mukushanda uye manejimendi emadziva ekushambira. Chechipiri, pasi diatomaceous rakashandiswawo zvakanyanya mumafuta anodyika, mishonga yemuromo zvinwiwa, uye mimwe minda.
Adsorbent:
Diatomaceous pasi rinoshandiswa zvakanyanya mukurapwa kwetsvina nekuda kwekugadzikana kwayo kwemakemikari zvimiro, yakasimba adsorption kugona, yakanaka kusefa kuita uye kusanyungudika mune chero yakasimba asidhi. Iko kusati kwagadziriswa kweanorasira leachate uchishandisa diatomaceous pasi flocculation precipitation nzira inogona kutanga yadzikisa CODCr neBOD5 mune leachate, kubvisa zvinosvibisa zvakaita seSS, uye inonyanya kushandiswa kumarara emumaguta, kugadzira mapepa, kudhinda nekudhaya tsvina, kuuraya tsvina ine mafuta. , uye heavy metal wastewater.
