Taariikhi: dhoobo-sameeyayaashu waxay samaysan jireen kooda iyagoo gubaya caws bariis, lamana iibiyo walax caadi ah ahaan. Kani waa hal muunad, oo ah caws bariis Colombia ah oo lagu gubay foorno bannaanka ah kadibna lagu kululeeyey 800 °C muddo 2 saacadood ah, aan la dhaqin. Dambaska cawsku wuxuu ku kala duwan yahay cawska, ciidda iyo gubidda: isla daraasaddaas, gubid kulul ayaa siisay silica badan iyo potash yar, dambaska caws bariiska ee Digitalfire wuxuu leeyahay 77.26% SiO₂ laakiin keliya 3.29% K₂O. Chlorine-kiisa 0.59% iyo sulfur-kiisa 1.74% halkan waxaa lagu tiriyaa wax gubidda ku lumay.
Falanqaynta oksaydhka iyo UMF (unity molecular formula)
Glazecalc wuxuu hayaa falanqaynta walaxda Rice-Straw Ash (藁灰) oo ah boqolkiiba miisaanka walaxda ceeriin. Qaybta UMF waa moles-ka oksaydh kasta ee ku jira xaddiga walaxda Rice-Straw Ash (藁灰) ee haysta 1.0 mole oo flux ah, taasina waa sida Glazecalc ugu daro UMF-ta habka.
| Oksaydh | Miisaan % | Qaybta UMF |
|---|---|---|
| SiO₂ | 79.62 | 6.644 |
| K₂O | 10.53 | 0.560 |
| CaO | 2.8 | 0.250 |
| P₂O₅ | 1.61 | 0.057 |
| MnO | 0.71 | 0.050 |
| MgO | 0.89 | 0.111 |
| Fe₂O₃ | 0.26 | 0.008 |
| Al₂O₃ | 0.27 | 0.013 |
| Na₂O | 0.35 | 0.028 |
- Miisaanka u dhigma (equivalent weight)
- 501.36
- Miisaanka kaddib gubidda
- 486.72
- LOI (lumista gubidda)
- 2.92%
Miisaanka u dhigma waa garaamada walaxda Rice-Straw Ash (藁灰) ee haysta 1.0 mole oo flux ah. Miisaanka kaddib gubidda waa inta ka hadha kaddib gubidda.
Khataraha iyo badbaadada
Khataraha: Wuxuu ka kooban yahay silica kiristaalka ah, dambaska aan la dhaqinna wuu gubaa maqaarka (caustic) marka uu qoyan yahay; xiro gacmo-gashi oo ka fogow neefsashada boodhka.
