Hoʻolauna

ʻAno:

1. He wai waihoʻoluʻu me ka ʻala ʻono a ʻala.

2. Volatile, wela loa, hiki ke hoʻoheheʻe ʻia i loko o nā mea hoʻoheheʻe organik a me nā waikawa inorganic.

 

Hoʻohana:

1. Ma ke ʻano he mea hoʻoheheʻe organik i hoʻohana nui ʻia i ka ʻoihana kemika, he hana koʻikoʻi ia i ka wehe ʻana i ka solvent, degreasing, a me ka hoʻomākaukau ʻana i nā mea hoʻomaʻemaʻe.

2. Biphenylhiki ke hoʻohana ʻia ma ke ʻano he mea maka a me ka waena no nā mea kemika like ʻole, hoʻohana ʻia i ka synthesis o nā dyes, plastics, rubber a me nā huahana ʻē aʻe.

3. Hiki ke hoʻohana ʻia ma ke ʻano he wahie hoʻohui, mea hoʻoluʻu automotive, a me kahi ʻāpana o nā mea pale mea kanu.

 

Hanana:

Nui nā ala, ʻo ka mea maʻamau ka pohā o ka lanahu. Ma o ka hoʻoheheʻe ʻana o ka lanahu, hiki ke loaʻa kahi hakina hui pū me ka biphenyl, a laila hiki ke loaʻa ka biphenyl maʻemaʻe kiʻekiʻe ma o ka hoʻomaʻemaʻe a me ka hoʻokaʻawale ʻana.

 

ʻIke palekana:

1. Biphenylhe wai wela e hiki ai ke hoʻoulu i ke ahi ke ʻike ʻia i nā kumu o ke ahi a i ʻole nā ​​wela kiʻekiʻe. No laila, he mea nui e kaʻawale i nā lapalapa ahi, nā kumu wela, a me ka uila paʻa.

2. He mea ʻawaʻawa ka biphenyl vapor a hiki ke hoʻonāukiuki i ka ʻōnaehana hanu, ʻōnaehana nerve, a me ka ʻili. No laila, pono e ʻaʻahu ʻia nā lako pale kūpono a pono e hōʻoia ʻia kahi wahi hana maikaʻi.

3. Hiki i nā biphenyls ke hoʻopōʻino i nā mea ola wai, no laila e pale ʻia lākou mai ka hoʻokuʻu ʻia ʻana i loko o nā kino wai.

4. I ka lawelawe ʻana a me ka mālama ʻana i nā biphenyls, pono e mālama pono i nā kaʻina hana palekana kūpono e pale aku i ka leakage a me nā pōʻino.
