ʻO ka sodium formaldehyde sulfoxylate (rongalite) pauda a me ka puʻupuʻu loaʻa nā ʻano penei:

1. He mea maʻalahi ka moisture exothermic, 80 ℃ hoʻomaka e decompose, ka hoʻokuʻu ʻana o H2S, pono e hoʻomaloʻo i ka mālama haʻahaʻa haʻahaʻa.

2. Ke piʻi ka mahana i 110 ℃, ka sodium formaldehyde sulfoxylate (rongalite) pauda a me ka puʻupuʻu piha decomposition, ka decomposition o formaldehyde i loko o ka mole i hoʻokuʻu ʻia i ke keiki hou [H], hoʻemi ʻia ka mana.

3. ʻO ka sodium formaldehyde sulfoxylate (rongalite) pauda a me ka puʻupuʻu ua decomposed i ka wā e hālāwai ai me ka mea hoʻoneʻe, e like me Iodine.

4. Pono ka sodium formaldehyde sulfoxylate (rongalite) pauda a me ka puʻupuʻu i loko o ka alkaline medium PH>8, acidic (ka palena ʻakika PH>3) hiki ke hana i ka sodium formaldehyde sulfoxylate (rongalite) pauda a me ka puʻupuʻu decomposition o ka hydrogen sulfide.

Kau: Me ka ulu wikiwiki o ka ikehu maʻemaʻe

Eia kekahi: ʻO ka nui o ka hana ʻana o ka Titanium Dioxide o koʻu ʻāina e hōʻea i 3.51 miliona mau tona ma 2020.
