Hoʻolauna

ʻO Octane kahi mea hoʻohuihui. Penei kona mau waiwai.

 

1. Nānā: wai kala ʻole

4. Māmā: 0.69 g/cm³

5. Hiki ke ahi: hiki ke puhi

 

ʻO ka Octane kahi hui i hoʻohana nui ʻia i nā wahie a me nā solvents. ʻO kāna mau hoʻohana nui he:

1. Mea hoʻohui wahie: Hoʻohana ʻia ʻo Octane i ka ʻaila ma ke ʻano he hui maʻamau no ka hoʻāʻo ʻana i ka helu octane e loiloi i ka hana anti-knock o ka ʻaila.

2. Enekinia wahie: Ma keʻano he wahie me ka ikaika o ka puhi ahi, hiki ke hoʻohana 'ia i nā mīkini hana kiʻekiʻe a i ʻole nā ​​kaʻa heihei.

3. Solvent: Hiki ke hoʻohanaʻia e like me ka mea hoʻoheheʻe ma nā kula o ka degreasing, ka holoi a me ka mea holoi.

 

ʻO nā ʻano hoʻomākaukau nui o ka octane penei:

1. Wehe ʻia mai ka ʻaila: Hiki ke hoʻokaʻawale ʻia ka Octane a lawe ʻia mai ka ʻaila.

2. Alkylation: Ma ka alkylating octane, hiki ke hoʻohui ʻia nā pūhui octane.

 

1. He wai wela ka Octane a pono e mālama ʻia ma kahi ʻoluʻolu, maloʻo, hoʻoluʻu maikaʻi ʻia, ma kahi mamao aku i ka ʻā a me nā mea oxidants.

2. I ka hoʻohana ʻana i ka octane, e hoʻokomo i nā mea pale kūpono e like me nā mīkina lima, nā maka aniani, a me nā lole pale.

3. E pale i ka pili octane me ka ili, ka maka, a me ka hanu hanu.

4. I ka lawelawe ʻana i ka octane, e pale i ka hana ʻana i nā ʻulaʻula a i ʻole ka uila paʻa i hiki ke kumu i ke ahi a pahū paha.
