Hoʻohana
Ma ke ʻano he mea hoʻopaʻa like i ka ʻōnaehana hoʻopaʻa calcium/zinc hydroxylate, hoʻohana ʻia ia e hana i nā ʻōmole wai mineral PVC.
Hiki ke hoʻohana ʻia ʻo Benzoylmethane ma ke ʻano he reagent analytical e hoʻoholo ai i ka carbon disulfide a me ka thallium, ka hoʻoholo gravimetric o ka uranium, ka hoʻoholo photometric o U+4, a me ka unuhi ʻana o ke kālā, alumini, barium, beryllium, calcium, cadmium, cobalt, keleawe, hao, gallium, mercury, propane, lanthanum, magnesium, manganese, nickel, lead, palladium, scandium, thorium, titanium, zinc, zirconium, etc.
ʻŌpala a me ka Hoʻouna ʻana
25KG/Drum a i ʻole e like me nā koi a ka mea kūʻai aku.
No nā waiwai maʻamau a hiki ke hāʻawi ma ke kai a me ka lewa
Mālama a me ka mālama ʻana
Ola papa: 24 mahina mai ka lā i hana ʻia ai i loko o ka pahu i wehe ʻole ʻia mua i mālama ʻia i kahi maloʻo a me kahi anuanu, mai ka lā pololei, ka wai.
Hale kūʻai ea, hoʻomaloʻo wela haʻahaʻa, hoʻokaʻawale ʻia mai nā mea hoʻomake a me nā waikawa.
