He aha ka PP i hana ʻia? ʻO kahi nānā kikoʻī i nā waiwai a me nā noi o ka polypropylene (PP)
I ka pili ʻana i nā mea palaki, ʻo ka nīnau maʻamau he aha ka PP i hana ʻia. Ma kēia ʻatikala, e loiloi mākou i nā kikoʻī i nā waiwai kemika a me ke kino o ka mea PP a me kāna ākea o nā noi ma nā ʻano like ʻole.
He aha ka PP?
ʻO PP (Polypropylene) inoa Kina no ka polypropylene, he resin synthetic i hana ʻia e ka polymerization o propylene monomer. Aia ia i ka hui polyolefin o nā plastics a ʻo ia kekahi o nā plastics i hoʻohana pinepine ʻia ma ka honua. Ua lilo nā mea polypropylene i pou koʻikoʻi o ka ʻoihana plastik ma muli o kā lākou hana maikaʻi loa a me nā kumu kūʻai haʻahaʻa haʻahaʻa.
ʻO ke kinona a me nā waiwai o PP
Mai kahi manaʻo kemika, he maʻalahi ka molecular structure o PP a he kalapona a me ka hydrogen atoms. He laina laina ʻo PP me nā ʻāpana propylene he nui i ke kaulahao mole, a hāʻawi kēia ʻano i ke kūpaʻa kemika maikaʻi a me ka stability. ka insulation a me ka haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa, e hoʻohana nui ʻia i nā māla uila a me ka uila.
Na Waiwai Kino o PP
ʻO nā waiwai kino o ka polypropylene e hoʻoholo i kona hoʻohanaʻana i nāʻano likeʻole. deformed.PP he wahi heheʻe kiʻekiʻe (160 a 170 ° C), hiki iā ia ke hoʻohana i nā mahana kiʻekiʻe me ka ʻole o ka deformed. deformation. Hana kēia mau waiwai kino i ka PP no ka hoʻopili ʻana, nā waiwai o ka hale a me nā ʻāpana kaʻa.
Nā wahi noi no nā mea PP
Ma muli o kāna mau waiwai maikaʻi loa, hoʻohana ʻia ʻo PP i kahi ākea o nā noi. I loko o ka ʻoihana hoʻopili, hoʻohana maʻamau ʻia ʻo PP e hana i nā ʻeke plastik, ʻeke meaʻai a me nā pāpale hue no ka mea ʻaʻole ia he mea ʻawaʻawa, ʻala ʻole a mālama i ka meaʻai hou no ka manawa lōʻihi. I ka lāʻau lapaʻau, hoʻohana ʻia ʻo PP e hana i nā syringes a me nā labware, i makemake ʻia no ko lākou kūpaʻa ʻana a me nā waiwai sterilization maikaʻi, a ma ka ʻoihana kaʻa, kahi i hoʻohana ʻia ai e hana i nā ʻoki kūloko a me nā bumpers, ma waena o nā mea ʻē aʻe, no ka maikaʻi o kona hopena maikaʻi a me nā waiwai māmā.
Pili kaiapuni a hoomau
Me ka hoʻonui ʻana i ka ʻike o ka mālama ʻana i ke kaiapuni, ua waiwai ʻia nā mea PP no kona recyclability. Hiki ke hoʻohana hou ʻia nā huahana PP ma o ka hana hou ʻana a i ʻole ka hoʻohana hou ʻana i nā kemika, e hōʻemi ana i ke kaumaha o ke kaiapuni.
Ka hopena
Hiki ke pane piha ʻia ka nīnau no ka mea i hana ʻia ai ka PP ma o kāna ʻano kemika, nā waiwai kino, a me ka laulā o nā noi. Inā makemake ʻoe i ke kumu kūʻai a me ka versatility i ke koho ʻana i kahi mea plastic, ʻaʻole kānalua ʻo PP kahi koho kūpono.
