Polypropylene vs Polyethylene

ʻO Polypropylene (PP) a me ka polyethylene (PE) ʻelua o nā mea thermoplastic i hoʻohana pinepine ʻia ma ka honua. ʻOiai kaʻana like lākou i nā ʻano like ʻole, loaʻa iā lākou nā ʻokoʻa like ʻole e kūpono ai kēlā me kēia mea no kekahi mau noi. I kēia manawa, e kamaʻilio mākou e pili ana i ka polypropylene a me ka polyethylene

ʻO ka Polypropylene kahi mea maʻalahi i hoʻohana ʻia i nā ʻoihana like ʻole, me ka automotive, packaging, a me ke kūkulu ʻana. He wahi heheʻe kiʻekiʻe kona, ʻo ia ka mea e pale ai i ka wela a me nā kemika. He mea maʻalahi hoʻi ia e maʻalahi e hana a hoʻoheheʻe. Ua ʻike ʻia ʻo Polypropylene no kona lōʻihi a me ka ikaika, kahi e kūpono ai no nā noi kahi mea nui ka paʻakikī.

ʻO ka Polyethylene, ma ka ʻaoʻao ʻē aʻe, he mea maʻalahi a palupalu i hoʻohana ʻia i ka nui o nā noi, e like me ka hoʻopili ʻana, ka pauka polyethylene, mahiʻai, a me ka mālama ola kino. He mea māmā ia e kū'ē i ka makū a me nā kemika. ʻO ka Polyethylene kekahi mea hoʻokalakupua uila maikaʻi, kahi kūpono no nā noi e koi ana i ka conductivity uila.

Ke pili i ko lākou mau waiwai kino, ʻokoʻa ka polypropylene a me ka polyethylene i nā ʻano like ʻole. ʻOi aku ka paʻakikī a ʻoi aku ka paʻakikī o ka polypropylene ma mua o ka polyethylene, ʻoi aku ka maʻalahi. ʻOi aku ka palupalu a ʻoi aku ka maʻalahi o ka polyethylene, ʻoi aku ka maikaʻi o ke kūpaʻa ʻana i ka hopena a me ka liʻiliʻi o ka pohā. ʻO ka polyethylene kekahi wahi hoʻoheheʻe haʻahaʻa ma mua o ka polypropylene, kahi e maʻalahi ai ka hana a me ka hoʻoheheʻe.

Ma ke kumu kūʻai, ʻoi aku ka liʻiliʻi o ka polyethylene ma mua o ka polypropylene. ʻO kēia no ka mea ʻoi aku ka maʻalahi o ka polyethylene i ka hana ʻana a koi ʻia ka hana liʻiliʻi ma mua o ka polypropylene. Eia naʻe, hiki ke ʻokoʻa ke kumukūʻai o kēlā me kēia mea depee pili ana i ka noi kiko'ī a me ka nui e pono ai.

I ka pili ʻana i ka hopena o ke kaiapuni, hiki ke hoʻohana hou ʻia ka polypropylene a me ka polyethylene a hiki ke hoʻohana hou ʻia i nā noi like ʻole. Eia nō naʻe, ua manaʻo ʻia ka polyethylene e ʻoi aku ka maikaʻi o ke kaiapuni ma mua o ka polypropylene, no ka mea, ua hana ʻia mai kahi ʻano kemika maʻalahi a koi ʻia ka liʻiliʻi o ka ikehu e hana ai.

I ka hōʻuluʻulu ʻana, ʻo ka polypropylene a me ka polyethylene ʻelua o nā mea thermoplastic i hoʻohana pinepine ʻia ma ka honua. ʻOiai kaʻana like lākou i nā ʻano like ʻole, loaʻa iā lākou nā ʻokoʻa like ʻole e kūpono ai kēlā me kēia mea no kekahi mau noi. ʻIke ʻia ʻo Polypropylene no kona ikaika a paʻa, ʻoiai ʻoi aku ka maʻalahi o ka polyethylene a kū i ka hopena. Ke koho ʻana ma waena o nā mea ʻelua, pono e noʻonoʻo i ka noi kikoʻī, nā waiwai kino, ke kumukūʻai, a me ka hopena o ke kaiapuni.
