Mawu Oyamba

Octane ndi organic pawiri. Makhalidwe ake ndi awa:

 

1. Maonekedwe: madzi opanda mtundu

4. Kuchulukana: 0.69 g/cm³

5. Kuyaka: kuyaka

 

Octane ndi mankhwala omwe amagwiritsidwa ntchito kwambiri pamafuta ndi zosungunulira. Ntchito zake zazikulu ndi izi:

1. Mafuta owonjezera: Octane amagwiritsidwa ntchito mu petulo ngati chigawo choyezera nambala ya octane kuti ayese ntchito yotsutsa kugogoda kwa petulo.

2. Mafuta a injini: Monga gawo la mafuta omwe ali ndi mphamvu zoyaka kwambiri, amatha kugwiritsidwa ntchito mu injini zogwira ntchito kwambiri kapena magalimoto othamanga.

3. Zosungunulira: Zitha kugwiritsidwa ntchito ngati zosungunulira m'minda ya degreasing, kutsuka ndi detergent.

 

Njira zazikulu zokonzekera octane ndi izi:

1. Otengedwa ku Mafuta: Octane ikhoza kukhala yokha ndikuchotsedwa mu petroleum.

2. Alkylation: Ndi alkylating octane, mankhwala ambiri a octane amatha kupangidwa.

 

1. Octane ndi madzi omwe amatha kuyaka ndipo amayenera kusungidwa pamalo ozizira, owuma, opanda mpweya wabwino, kutali ndi kuyatsa ndi okosijeni.

2. Mukamagwiritsa ntchito octane, valani zida zodzitetezera zoyenera monga magolovesi, magalasi, ndi zovala zodzitetezera.

3. Pewani kukhudzana ndi octane ndi khungu, maso, ndi kupuma.

4. Pogwira ntchito ya octane, pewani kutulutsa zoyaka kapena magetsi osasunthika omwe angayambitse moto kapena kuphulika.
