He aha ka polypropylene? -Nā Waiwai, Nā noi a me nā pono o ka Polypropylene
He aha ka Polypropylene (PP)? ʻO ka Polypropylene kahi polymer thermoplastic i hana ʻia mai ka polymerisation o propylene monomers a ʻo ia kekahi o nā mea i hoʻohana nui ʻia i ka honua. Ma muli o kāna mau waiwai kemika a me ke kino, noho ka polypropylene i kahi kūlana koʻikoʻi i ka ʻoihana ʻoihana, ka lāʻau lapaʻau, ka hale a me nā noi hoʻopili meaʻai. Ma kēiaʻatikala, e nānā hohonu mākou i nā waiwai kumu o ka polypropylene, kāna mau noi nui a me kāna mau pono.
Nā waiwai kumu o ka polypropylene
He aha ka polypropylene? Ma ke ʻano o ka hoʻolālā kemika, ʻo ka polypropylene kahi polymer i hana ʻia e ka polymerization hoʻohui o nā monomers propylene. ʻO kona ʻano molekala he symmetric kiʻekiʻe a loaʻa mau i kahi ʻano semi-crystalline. Hāʻawi kēia symmetry a me ka crystalline i ka polypropylene i nā waiwai kino maikaʻi loa, e like me kahi helu heheʻe kiʻekiʻe, haʻahaʻa haʻahaʻa a me ke kūpaʻa kemika maikaʻi. ʻO ka helu heheʻe o Polypropylene ma waena o 130°C a me 171°C, hiki iā ia ke noho paʻa morphologically i nā wela kiʻekiʻe. Me ka mānoanoa ma kahi o 0.9 g/cm³, ʻoi aku ka māmā o ka polypropylene ma mua o ka nui o nā plastik maʻamau e like me ka polyethylene a he kūpaʻa maikaʻi loa.
Nā noi nui no ka polypropylene
He aha ka polypropylene? He aha kāna mau noi ma nā ʻoihana like ʻole? Ma muli o kāna mau waiwai like ʻole, hoʻohana ʻia ka polypropylene i kahi ākea o nā noi. I ka ʻoihana hoʻopili, hoʻohana ʻia ka polypropylene i nā mea nui no nā huahana e like me ka hoʻopili meaʻai, nā pāpale a me nā kiʻiʻoniʻoni. ʻO kona kūpaʻa kemika a me ke kūpaʻa wai e kūpono ia no ka ʻeke meaʻai, e hōʻoia i ka palekana o ka meaʻai a me ke ola o ka papa. I ka ʻāpana lako hale, hoʻohana ʻia ka polypropylene e hana i nā lako, nā ipu a me nā textiles, ma waena o nā mea ʻē aʻe, ma muli o kona kaumaha māmā a me ka lōʻihi, a me ka maʻalahi o ka hoʻomaʻemaʻe a me ka mālama ʻana. Eia kekahi, i ka ʻoihana mālama olakino, hoʻohana ʻia ka polypropylene e hana i nā syringes, nā paipu hoʻāʻo a me nā mea lapaʻau ʻē aʻe ma muli o kona biocompatibility maikaʻi a me nā waiwai antimicrobial.
Nā Pōmaikaʻi Polypropylene a me nā mea e hiki mai ana
I ka wā e pili ana i ka polypropylene, ʻo kāna mau pōmaikaʻi koʻikoʻi e pili ana i ka wela a me ka pale kemika, a me nā kumu kūʻai haʻahaʻa. Hiki i ka polypropylene ke hoʻoheheʻe kiʻekiʻe ke hoʻohana ʻia i nā mahana kiʻekiʻe me ka pilikia ʻole o ka distortion a me ka heheʻe. ʻO kona kūpaʻa kemika maikaʻi e hiki ai i ka polypropylene ke kūpaʻa a ʻaʻole e ʻino i ka wā e ʻike ʻia ai i nā waikawa, alkalis a me nā mea hoʻoheheʻe organik. ʻO ke kaʻina hana maʻalahi a haʻahaʻa haʻahaʻa o ka Polypropylene ua alakaʻi i kona hoʻohana nui ʻana i nā ʻano huahana like ʻole i ke ola o kēlā me kēia lā.
Ke ulu nei ka ʻike kaiapuni, ua lilo ka hana hou ʻana o polypropylene i mea waiwai nui. Hiki i ka ʻenehana hou ke hana hou i nā mea ʻōpala polypropylene, kahi e hōʻemi nui ai i ka pau ʻana o nā kumu waiwai a me ka pollution kaiapuni. No laila, ʻo ka hoʻomohala ʻana o nā mea polypropylene i ka wā e hiki mai ana e uku nui i ka mālama ʻana i ke kaiapuni a me ka hoʻomau, a hoʻonui hou i kāna hana a me ka hoʻohana ʻana ma o ka ʻenehana ʻenehana.
Ka hopena
He aha ka mea polypropylene? Hōʻike ka ʻike kikoʻī o kēia pepa i ka polypropylene he polymer thermoplastic me kahi ākea o nā noi a me nā waiwai maikaʻi he nui. ʻO kona wahi hoʻoheheʻe kiʻekiʻe, kūpaʻa kemika, paona māmā, a me ke kumu kūʻai haʻahaʻa he mea nui ia i nā ʻoihana he nui. Me ka hoʻomohala ʻana i nā ʻenehana pili i ke kaiapuni, ua mākaukau ka polypropylene no nā noi ʻoi aku ka maikaʻi i ka wā e hiki mai ana. Inā ʻoe e ʻimi nei i kahi mea kiʻekiʻe kiʻekiʻe a me ka uku kūpono, ʻo ka polypropylene kahi koho kūpono e noʻonoʻo ai.
