1. Nā ʻokoʻa i ka noi.
Pihi o ka hoʻohana ʻana oPepa PE: hoʻohana nui ʻia i ka ʻoihana kemika, ka mīkini, ka ʻoihana kemika, ka uila, ka lole, ka pahu, ka meaʻai a me nā ʻoihana ʻē aʻe. Hoʻohana nui ʻia ia i ka lawe ʻana i ke kinoea, ka hoʻolako wai, ka hoʻokuʻu ʻia ʻana o ka wai, ka irrigation mahiʻai, ka lawe ʻana i ka paʻa paʻa i loko o nā mines, a me ka māla aila, ʻoihana kemika, pou a me ke kelepona, etc.
ʻO ka pālākiō hoʻohana ʻana o ka pā PP: no nā mea ʻakika a me nā mea alkaline, nā mea hoʻomalu kaiapuni, ka wai ʻōpala a me nā lako hoʻokuʻu ʻana i ke kinoea, ka hale kiaʻi, ka lumi lepo ʻole, nā lako o ka hale semiconductor a me kāna mau ʻoihana pili, a me nā mea makemake no ka hana ʻana i ka pahu wai plastik. I loko o kēia manawa, hoʻohana nui ʻia ka pā mānoanoa PP no ka stamping plate, punch pad, etc.
2. Nā ʻokoʻa o nā ʻano.
He palupalu ka papa PE a he ʻano paʻakikī, a ʻoi aku ka maikaʻi o ka hopena a me ka hana cushioning, ʻoi aku ka maikaʻi o ka hana o ka papa i hoʻoheheʻe ʻia; He kiʻekiʻe ka paʻakikī o ka papa PP, nā waiwai mechanical maikaʻi ʻole, haʻahaʻa haʻahaʻa a me ka hopena maikaʻi ʻole.
3. Nāʻokoʻa i nā mea.
ʻO ka pā PP, i kapa ʻia ʻo polypropylene (PP) pā, he mea semi-crystalline. ʻOi aku ka paʻakikī ma mua o ka PE a ʻoi aku ka nui o ka heheʻe. ʻO ka pepa PE he ʻano resin thermoplastic me ka crystallinity kiʻekiʻe a me ka polarity ʻole. ʻO ka hiʻohiʻona o ka HDPE mua he keʻokeʻo waiū, a he translucent i kekahi ʻano ma ka ʻāpana lahilahi.
