ʻO ka polyethylene plastic ka polyethylene ma ke ʻano nui

ʻO ka mea nui o ka polyethylene plastic he polyethylene. Loaʻa ka nui o kāna mea ethylene mai ka petroleum cracking a me ka haki ʻana, nona nā huahana petrochemical.

Polyethylene (PE) ʻO ia kekahi o nā resins synthetic nui ʻelima, a ʻo ia ka ʻano me ka mana hana nui loa a me ka nui o ka lawe ʻana mai ma waena o nā resins synthetic ma koʻu ʻāina. Hoʻokaʻawale nui ʻia ka polyethylene i ʻekolu mau ʻāpana: linear low-density polyethylene (LLDPE), low-density polyethylene (LDPE), a me high-density polyethylene (HDPE).

He palupalu ka PE a he ʻano waxy i ka hoʻopā ʻana. Ke hoʻohālikelike ʻia me ka plastic like, ʻoi aku ka maʻalahi o ke kaumaha a loaʻa kekahi ʻano o ka ʻike. Ke ʻā, uliuli ka lapalapa.
