He aha nā mea pp?
He pōkole loaʻo PP no ka polyproylene, he poʻokela o ka nūpepa i hanaʻia i ka polimaila o Pymeromua. E like me kahi mea nui o ka plastik i kahi nui, he pp he nui o nā noi i kēlā me kēia lā i kēlā me kēia lā a me ka hanaʻoihanaʻoihana. Ma kēiaʻatikala, e nānā mākou i nā kiko'ī e pili ana i ka mea pp, e like me konaʻano, hoʻohana a me nā pono.
ʻO nā hiʻohiʻona maʻamau o nā kumu pp
ʻO nā mea pp waiwai maikaʻi loa a me nā waiwai kūpono. He haʻahaʻa loa kona hanaʻana, e pili ana iā 0.9 g / cm³,ʻo ia ka mea nui loa o ka paleʻana o nā plastic maʻamau. , a me ka hapa nui o nā maʻi maʻi,ʻo Alkaliis a me nā mea hoʻoponopono a me nā organic Ma muli o kēia mau pono, ua lilo nā mea pp i kahi koho kūpono kūpono i nā mahina he nui.
ʻO ka helu a me ka hoʻololiʻana o nā mea pp
Hiki ke heluʻia nā lako PP iʻelua mau papa nui,ʻo Homopolymer polyproopylene a me Copolymer polyPopylene He kiʻekiʻeʻo Homopollymer i nā mea kiʻekiʻe a me ka ikaika, e kūpono ana i nā huahana Vinling e hoʻololiʻia e ka hoʻohuiʻana i nā fibers kīwī, nā mea kūʻai aku, a iʻole nā ​​retadants e hoʻomaikaʻi i kona mau mea ola kino. Hiki ke hoʻololiʻiaʻo PP i ka hoʻohuiʻana i nā kīlei kīwī a iʻole nā ​​mea hou i nā mea kūʻai aku a iʻole nā ​​mea e hiki ke hoʻomaikaʻi i kahiʻano o ka nui o nā noi.
Nā palapala noi o nā mea pp
Hiki ke loaʻa nā mea pp i nā wahi a pau i ke ola, a uhiʻia ko lākou mau noi i kahi ākea ākea a me nā lako lāʻau i nā hale kaʻa a me nā lako lāʻau. Ma ke kahua o ke kīwī, ua hoʻohana nuiʻiaʻo PP ma ka hanaʻana o nā lāʻau lapaʻau meaʻai, nā huahana'ē aʻe,ʻaʻole ia he mau'āpana maikaʻiʻole. I nā huahana hale, ua hoʻohana pinepineʻia ka waiwai pp e hana i nā pahu mālama, nā mea kanu lāʻau, nā mea hale a pēlā aku. Ma muli o kāna wela wela a me ke kū'ēʻana, ua hoʻohana pūʻiaʻo PP i kaʻoihana kaʻa, e like me nā mea hana hoʻohālikelike a me nā mea hoʻonaninani.
Kūlohelohe a hoʻomālamalama
I kēia mau makahiki i hala iho nei, e like me kaʻikeʻana i kaʻikeʻana, ua loaʻa hou nā huahana pp ma muli o ko lākou recyclability a me ka hopena o ke kaiāulu. Hiki ke hōʻoiaʻia nā huahana PP ma o ka recycling ma hope o ka haʻaleleʻana, e hōʻemi ana i ka haumia i ke kaiapuni. ʻOiaiʻaʻole hiki i ka mea pp o ke kumu biodegratable No laila, ua manaʻoʻiaʻo PP Pūnaeweleʻo PP i kahiʻano pilikino maikaʻi a mālamaʻia nā polokalamuʻulaʻula.
Hōʻaʻakeʻa
ʻO nā mea pp he mau mea plastitally i nā lako plastitile me nāʻano ākea ākea. Kona mau haʻahaʻa haʻahaʻa, ke pale wela, ke kū'ēʻana i ka paleʻana a me ka recyclability a me reclaclabublility e hana ia i kekahi o nā mea i loaʻa i loko o kaʻoihana i kēia manawa a me kēlā me kēia lā o ke ola. Ma ka hoʻomaopopoʻana i nā mea pp a me kona mau wahi o ka noi, hiki iāʻoe ke hoʻohana maikaʻi i nā pono o kēia mea e hāʻawi ai i nāʻano kūpono o nā huahana.
