Makaʻala Mākeke: Ke piʻi aʻe nei nā kumukūʻai FRP a me kā mākou mau kumu kūʻai
Ma muli o nā hoʻopaʻapaʻa hou e pili ana iā Iran, ua piʻi nā kumukūʻai aila honua. ʻO ka Polyester Resin kahi huahana petrochemical kiʻekiʻe a me ka mea kumu mua no nā pepa FRP. No laila, pili maikaʻi loa kona kumukūʻai me ka ʻaila ʻaila, e alakaʻi ana i ka piʻi mau ʻana o ke kumukūʻai no nā pepa FRP ma waena o ka ʻoihana i kēia manawa.
Ma ke ʻano he mea hana pepa FRP, ua manaʻo mākou i kēia mau loli. Mahalo i kā mākou mālama waiwai maka, hiki iā mākou ke mālama i kā mākou mau kumu kumu kūʻai mua me ka ʻole o ka piʻi koke ʻana no kā mākou mau hoa.
Ke ʻike nei ʻoe i ka like ʻole o ke kumukūʻai ma kāu mākeke? E mālama anei ʻoe i nā pepa FRP no kāu mau papahana kino kaʻa?
PS: hoʻonui ʻike pili
ʻO ka resin polyester kahi huahana maʻamau i lalo o ka ʻoihana petrochemical, a ʻo kona mau kumukūʻai i hoʻopili maikaʻi ʻia me nā kumukūʻai aila. ʻO ke ala hoʻouna kaulahao hoʻolako penei: ʻO ka ʻaila ʻaila: ʻO ka mea maʻamau loa. Naphtha: He huahana o ka ʻaila hoʻomaʻemaʻe. PX (para-xylene) & Benzene: Loaʻa mai ka naphtha māhā a hoʻoponopono paha. PTA (kaʻakika terephthalic i hoʻomaʻemaʻe ʻia) & Ethylene glycol (EG) / Neopentyl glycol (NPG): Hoʻopuka ʻia ka PTA e ka oxidation o PX. ʻO ka ethylene glycol a me ka neopentyl glycol ka mea nui i loaʻa mai nā mea hoʻoheheʻe ʻaila (hiki ke hoʻomākaukau ʻia kekahi mau neopentyl glycol ma ke ʻano isobutyraldehyde, akā pili mau ke kumu i nā kumukūʻai ikehu). Polyester resin: Hana ʻia e ka polycondensation reaction o PTA, ethylene glycol, neopentyl glycol, etc.
Nā pepa pepa FRP no ke kino kaʻa
