Hoʻolauna

ʻO ka melemele 181 he puaʻa olaola me ka inoa kemika o ka phenoxymethyloxyphenylazolizoyl barium.

 

ʻO ka puaʻa melemele 181 ka waihoʻoluʻu melemele a maikaʻi loa ka paʻa māmā a me ka lōʻihi. He kūpaʻa loa ia i nā mea hoʻoheheʻe a me ka māmā, a ʻaʻole hiki ke hoʻopau a mae. ʻO ka melemele 181 ka wela maikaʻi a me ka pale kemika.

 

Hoʻohana nui ʻia ka melemele 181 ma ke ʻano he kala i loko o nā ʻoihana e like me ka inika, plastics, coatings, and rubber. Hoʻohui kona waihoʻoluʻu melemele i ka nani a me ka nani o ka huahana. Hoʻohana pinepine ʻia ka melemele 181 i ka hoʻoluʻu lole, pena kiʻi a me ka paʻi ʻana.

 

Hana ʻia ka hoʻomākaukau ʻana o Huang 181 e nā ʻano kemika synthetic. ʻO ke ʻano kikoʻī, hoʻopili mua ʻia ka phenoxymethyloxyphenyl triazole, a laila hana ʻia me ka barium chloride e hana i ka puaʻa melemele 181.

E hō'ole i ka hanu'ana i ka lepo melemele 181 a i'ole ka hopena, a pale i ka pili'ana o ka ili a me ka maka. I ka mālama ʻana a me ka mālama ʻana i ka Yellow 181, pono e mālama ʻia nā hoʻoponopono kūloko, a mālama ʻia ma kahi maloʻo a maikaʻi. Inā ʻaʻole ʻoe i ʻai a i ʻole i hui pū me Huang 181, pono ʻoe e ʻimi koke i ka lāʻau lapaʻau.
