formic acid) he wai waihoʻoluʻu me ka ʻala ʻala. Eia na waiwai nui o ka waika formic:

 

Nā waiwai kino: Hiki ke hoʻoheheʻe ʻia ka waika Formic a hiki ke hoʻoheheʻe ʻia i ka wai a me ka hapa nui o nā mea hoʻoheheʻe organik.

 

Nā waiwai kemika: ʻO ka waika Formic he mea hoʻoemi maʻalahi e hoʻoheheʻe ʻia i carbon dioxide a me ka wai. Hoʻopili ka hui me kahi kumu ikaika e hana i ka formate.

 

ʻO nā hoʻohana nui o ka formic acid penei:

 

Ma ke ʻano he disinfectant a me ka preservative, hiki ke hoʻohana ʻia ka formic acid i ka hoʻomākaukau ʻana i nā mea pena a me ka ʻili.

 

Hiki ke hoʻohana ʻia ka waika formic ma ke ʻano he mea hoʻoheheʻe hau a me ka mea pepehi mite.

 

ʻElua mau ala nui e hoʻomākaukau ai i ka waika formic:

 

ʻO ke ala kuʻuna: ʻO ke ʻano distillation e hana ai i ka waiuma formic ma o ka hoʻoheheʻe ʻia ʻana o ka lāʻau.

 

ʻO ke ʻano o kēia wā: hoʻomākaukau ʻia ka waika formic e ka methanol oxidation.

 

ʻO nā mea e mālama ai no ka hoʻohana palekana ʻana i ka waika formic penei:

 

ʻO ka waika Formic he ʻala ʻala a me nā waiwai corrosive, no laila pono ʻoe e hoʻokomo i nā mīkina lima pale a me nā aniani i ka wā e hoʻohana ai.

 

E hōʻalo i ka hoʻohu ʻana i ka formic acid vapor a i ʻole ka lepo, a e hōʻoia i ka maikaʻi o ka ea i ka wā e hoʻohana ai.

 

Hiki i ka waika Formic ke hoʻopau i ka puhi ʻana a pono e mālama ʻia mai ke ahi a me nā mea hiki ke puhi ʻia.
