Nha.1PH yayo inenge isina kwayakarerekera, uye ine yakagadzikana makemikari zvimiro, haina kemikari inoita kune zvinhu zvakaita seCu, Fe, l uye Co, nezvimwe, zvichivimbisa kushanda kwefomula.
Kemikari zita: Silicon dioxide
Fomula: SiO2
Molecular uremu: 60.09
Chitarisiko: Hupfu chena, anti-caking, yakanaka fluidity
Muviri uye Chemical chiratidzo:
Item | Indicator |
SiO2,% | 96 |
rsenic (As), mg/kg | ≤3 mg/kg |
Kutungamira (Pb), mg/kg | ≤5 mg/kg |
Cadmium(Cd), mg/lg | ≤0.5 mg/kg |
Mercury (Hg), mg/kg | ≤0.1mg/kg |
Chikamu saizi | 150 µm (100mesh) ≥95% |
pH | ≥6.0 |
Kurasikirwa pakuomeswa | ≤5% |
Isu takaita ongororo yakasimba yeese chikamu uye chigadzirwa, tichiedza kusave nemhando matambudziko mumaoko evatengi.
Fekitari yakananga yekutengesa, hapana pakati pemutengo musiyano.
Pindura mubvunzo wemutengi mukati memaawa makumi maviri nemana, uye injiniya webasa achange akamirira maawa makumi maviri nemana pazuva.
Ndapota taura nesu kuti uwane rumwe ruzivo.
