Hoʻolauna

ʻO Styrene, he wai kala ʻole me kahi ʻala ʻala kūikawā. ʻO kēia ka hoʻolauna ʻana i nā waiwai, hoʻohana, nā ʻano hoʻomākaukau a me ka ʻike palekana o styrene:

 

ʻAno maikaʻi:

1. ʻOi aku ka māmā.

2. He mea maʻalahi ma ka lumi wela a he haʻahaʻa ka helu uila a me ka palena pahū.

3. Hiki ke hoʻopili ʻia me nā ʻano mea hoʻoheheʻe kūlohelohe a he mea koʻikoʻi loa ia.

 

E hoʻohana:

1. He mea koʻikoʻi kemika ʻo Styrene, hoʻohana pinepine ʻia i ka synthesis o ka nui o nā plastics, synthetic rubber a me nā fibers.

2. Hiki ke hoʻohanaʻia ka Styrene e hana i nā mea synthetic e like me ka polystyrene (PS), polystyrene rubber (SBR) a me ka copolymer acrylonitrile-styrene.

3. Hiki ke hoʻohana ʻia no ka hana ʻana i nā huahana kemika e like me nā mea ʻono a me nā aila lubricating.

 

Hanana:

1. Hiki ke loaʻa iā Styrene ma ka dehydrogenation ma ka hoʻomehana ʻana a me ke kaomi ʻana i nā molekole ethylene.

2. Hiki ke loaʻa ka Styrene a me ka hydrogen ma ka hoʻomehana ʻana a me ka haki ʻana i ka ethylbenzene.

 

ʻIke palekana:

1. He mea wela ka Styrene a pono e pale ʻia mai ka ʻā a me nā wela kiʻekiʻe.

2. Hiki i ka ho'opili 'ana me ka 'ili ke ho'onāukiuki a me ka ma'i ma'i, a pono e mālama pono 'ia.

3. Loa'a paha i ka 'ike 'ana i ka wā lō'ihi a i 'ole ka nui o nā hopena olakino, e like me ka pō'ino i ka pu'uwai, ate, a me nā pu'upa'a.

4. E noʻonoʻo pono i ke ʻano o ka ea i ka wā e hoʻohana ai, a pale i ka inhalation a i ʻole ka ʻai ʻana.

5. Pono ka hoʻolei ʻana i ka ʻōpala i nā kānāwai a me nā lula pili, a ʻaʻole pono e hoʻolei ʻia a hoʻokuʻu ʻia ma ka makemake.
