Mea kūʻai aku ʻo Caustic soda flakes
ʻO ka sodium hydroxide (NaOH), i ʻike ʻia ʻo ka soda caustic, lye a me kahi ʻāpana alkali, he pūhui inorganic.He paʻa paʻa keʻokeʻo a me ka paʻakai alkali o ka sodium i loaʻa i loko o nā pellets, flakes, granules, a me nā hoʻonā i hoʻomākaukau ʻia ma nā ʻano ʻokoʻa like ʻole.Hoʻokumu ʻia ka sodium hydro xide i kahi hopena saturated ma kahi o 50% (ma ke kaumaha) me ka wai.;Hiki ke hoʻoheheʻe ʻia ka sodium hy droxide i ka wai, ethanol, a me me thanol.He deliquescent kēia alkali a komo koke i ka makū a me ka carbon dioxide i ka ea.
Hoʻohana ʻia ka sodium hyd roxide i nā ʻoihana he nui, ʻo ka hapa nui he kumu kemika ikaika i ka hana ʻana i ka pulp a me ka pepa, nā textiles, ka wai inu, nā kopa a me nā mea hoʻomaʻemaʻe a me ka hoʻomaʻemaʻe wai.

lehu kopa
ʻO ka lehu soda kekahi o nā mea kumu no ka ʻoihana kemika, hoʻohana nui ʻia no ka metallurgy, aniani, textile, dye paʻi, lāʻau lapaʻau, synthetic detergent, petroleum a me ka ʻoihana meaʻai etc.
1. Inoa: Soda lehu mānoanoa
