Hoʻolauna

ʻO ka Melamine (ke kumu hoʻohālike C3H6N6) he pūhui olaola me nā ʻano waiwai a me nā hoʻohana.

 

ʻAno maikaʻi:

1. Nā waiwai kino: ʻO ka Melamine he paʻa kalakala kala ʻole me nā helu hoʻoheheʻe kiʻekiʻe a me ka paila.

2. Nā waiwai kemika: ʻO ka Melamine kahi pūhui paʻa ʻaʻole maʻalahi ke hoʻoheheʻe ʻia i ka mahana wela. Hiki ke hoʻoheheʻe ʻia i ka wai a me kekahi mau mea hoʻoheheʻe kūlohelohe e like me ka methanol a me ka acetic acid.

 

E hoʻohana:

1. Ma ka ʻoihana, hoʻohana pinepine ʻia ka melamine ma ke ʻano he mea maka no nā resins synthetic, e like me ka fiber acrylic, phenolic plastics, etc.

 

2. Hiki ke hoʻohana ʻia ka melamine e like me ka pale ahi, nā mea hoʻonaninani, nā puaʻa a me nā mea hoʻohui pepa.

 

Hanana:

Hana ʻia ka hoʻomākaukau ʻana o ka melamine e ka hopena o ka urea a me ka formaldehyde. Hoʻopili ka Urea a me ka formaldehyde ma lalo o nā kūlana alkaline e hana i ka melamine a me ka wai.

 

ʻIke palekana:

1. He haʻahaʻa haʻahaʻa ko ka Melamine a he liʻiliʻi ka hopena i ke kanaka a me ke kaiapuni.

 

3. I ka hoʻohana ʻana a me ka mālama ʻana i ka melamine, e pale i ka hoʻopili ʻana me ka ʻili a me nā maka, a hoʻokomo i nā mīkina lima pale a me nā maka aniani inā pono.

4. Ma ka hoʻolei ʻana i ka ʻōpala, pono e mālama ʻia nā kānāwai a me nā lula pili e pale aku ai i ka haumia o ke kaiapuni.
