I ke koho ʻana i nā mea kūpono no kāu papahana, ʻo ka koho ma waena o nā pepa PP a me nā pepa PPH he mea nui. ʻOiai ʻoi aku ka maikaʻi o nā koho ʻelua i nā noi like ʻole, he mea koʻikoʻi ka hoʻomaopopo ʻana i kā lākou mau waiwai a me nā hiʻohiʻona. Ma kēia pou blog, e ʻimi mākou i nā hiʻohiʻona, nā pōmaikaʻi, a me nā hihia hoʻohana maikaʻi loa noPepa PPs aPepa PPHs.
PolypropyleneKaulana ʻia nā lau (PP) no ko lākou ikaika, kūpaʻa, a me ka versatility. Hāʻawi kēia mau pepa māmā i ke kūpaʻa kemika maikaʻi loa, e hoʻolilo iā lākou i mea kūpono no nā noi ʻoihana like ʻole a me nā ʻoihana. Hoʻohana nui ʻia nā pepa PP i ka ʻeke, automotive, a me nā ʻoihana mea kūʻai aku, ma muli o ko lākou haʻahaʻa haʻahaʻa haʻahaʻa a me ke kū ʻana i ka hopena a me nā ʻōpala. ʻIke ʻia kēia mau pepa no ko lākou kūʻē ʻana i nā ʻakika, nā kumu, a me nā solvents.
ʻO nā pepa polypropylene homopolymer (PPH) kaʻana like me nā pepa PP, akā loaʻa iā lākou kekahi mau hiʻohiʻona kūʻokoʻa.Pepa PPHs he kiʻekiʻe kiʻekiʻe o ka rigidity a me ka ikaika, e hoʻolilo iā lākou i mea kūpono no ke koi ʻana i nā noi e pono ai ka hoʻonui ʻana i nā waiwai mechanical. Hōʻike lākou i ke kūpaʻa wela maikaʻi, hāʻawi i ka hana ʻokoʻa i nā kaiapuni wela kiʻekiʻe. Eia kekahi, pale ʻia nā lau PPH i ka haki ʻana a hōʻike i ke kūpaʻa kemika lōʻihi.
I ka hoʻohālikelike ʻana i nā pepa PP a me nā pepa PPH, ʻike ʻia ka ʻokoʻa o kā lākou waiwai a me nā mea hana. ʻOiai kaʻana like nā mea ʻelua i nā pono maʻamau e like me ke kūpaʻa kemika a me ka lōʻihi, hāʻawi nā pepa PPH i ʻoi aku ka ikaika mechanical a me ka pale wela e hoʻohālikelike ʻia me nā pepa PP. No laila, makemake pinepine ʻia nā pepa PPH i nā noi kahi e pono ai ka paʻakikī a me ke kūpaʻa.
I ka hopena, koho ma waenaPepa PPs a me nā pepa PPH e hilinaʻi i ka hoʻomaopopo ʻana i nā koi kūikawā o kāu papahana. E noʻonoʻo i nā mea e like me ke kūpaʻa kemika, ka ikaika mechanical, a me ke kūpaʻa wela e hoʻoholo i ka ʻike.
