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 zvemigodhi yepasi diatomaceous 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 ye 19-65cm2/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. Semuenzaniso, kushandiswa kwe diatomaceous earth filtration mukugadzira winemaking kunogona kuenderera mberi nekugadzirisa mubhedha wesefa, kukurumidza kusefa nekukurumidza, goho guru; Nenzvimbo yakakura uye yakasimba adsorption simba, inogona kusefa zvimedu kubva 0.1 kusvika 1.0 μ m, kuderedza doro kurasikirwa neanenge 1.4%, uye kuvandudza kugadzirwa kwemamiriro ekushanda. Diatomaceous pasi mafirita anogona kuvandudza 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 earth flocculation precipitation nzira inogona kutanga kuderedza CODCr neBOD5 muleachate, kubvisa zvinosvibisa zvakaita seSS, uye inonyanya kushandiswa kumvura yedhorobha, kugadzira mapepa emarara, kudhinda nekudhaya tsvina, kuuraya tsvina ine mafuta, uye inorema tsvina yemvura.
