Inā ʻoi aku ka maikaʻi o ka hana ʻana i nā kīʻaha palaki me ka PP a i ʻole ka PET?

Nā kīʻaha palakihe mea maʻamau i ko mākou ola, hoʻohana pinepine mākou i nā kīʻaha plastik e hoʻopiha i ka wai a i ʻole nā ​​​​mea inu. Nui nā ʻano kīʻaha plastik, hiki ke hoʻopiha ʻia kekahi mau kīʻaha plastik me ka wai wela, akā hiki ke hoʻopiha wale ʻia kekahi mau kīʻaha plastik me ka wai anuanu. I ka manawa like, e ʻokoʻa hoʻi nā mea like ʻole i ke ʻano. ʻO ke ola a mākou e hoʻohana ai i nā kīʻaha plastik i hana pinepine ʻia me ka mea PP a me PET, e nui ka poʻe e kau ana ma ke kīʻaha plastik he mea PP a i ʻole ka mea PET he mea maikaʻi ia i kēia pilikia e manaʻo nei he kānalua? No kēia pilikia, ʻo ka mea liʻiliʻi e hiki mai ana e pane iā ʻoe, e hui koke mai nā hoaaloha hoihoi e ʻike!
He polypropylene ka PP, he polyester ka PET. Ma ke kumumanaʻo, ʻaʻohe mea ʻawahia nā mea ʻelua, akā ma ke ʻano o ke kūpaʻa ʻana i ka ʻelemakule a me ke kūpaʻa ʻana i ka wā, ʻoi aku ka kūpono o PP no nā kīʻaha wai, he kūpaʻa maikaʻi ko PP i ka wela, hiki ke kū i nā mahana kiʻekiʻe o 120 degere, ʻo ia wale nō ka mea plastik hiki ke hoʻokomo ʻia i loko o ka microwave.

Nā noi Polypropylene (PP): nā kīʻaha microwave, nā ipu hao, nā bākeke plastik, nā pūpū thermos, nā ʻeke ulana, a pēlā aku. Nā ʻano: ke kūpaʻa kemika kiʻekiʻe, ka hana olakino maikaʻi, ke kūpaʻa wela kiʻekiʻe. Hiki ke hoʻohana ʻia nā mea ʻaina Microwave i hōʻailona ʻia nā huahana plastik PP. ʻAwaʻawa: ʻaʻohe ʻawaʻawa, ʻaʻohe mea ʻino i ke kino kanaka. Hiki i ka polymer ke loaʻa i ʻekolu ʻano ʻekolu-dimensional: isometric, intergraphic, atactic polypropylene, hiki i nā mea mua ʻelua ke crystallize, ʻaʻole hiki i ka mea hope. ʻO nā huahana polypropylene i loaʻa i ke kālepa ke ʻano o ka mākeke iso-gauge, he 164 ~ 170 degere Celsius ka heheʻe ʻana o ka wahi, ʻo ka nui o ka crystalline he 0.935 grams / cubic centimeters, ʻo ka ʻāpana maʻemaʻe ʻole he 0.851 grams / cubic centimeters. ʻO ka drawback nui loa o PP, he maʻalahi ka oxidize a me ka ʻelemakule. I kēia manawa me ka hoʻohui ʻana o nā antioxidants a me nā mea hoʻomoʻa ultraviolet e lanakila ai.
Nā noi Polyester (PET): nā ʻōmole inu plastik, nā ʻōmole lāʻau lapaʻau, nā ʻōmole hoʻonani, nā ʻōmole ʻaila, a me nā ʻano pāpale ʻōmole like ʻole, uhi insulation. Nā ʻano: maikaʻi ka moakaka, ʻaʻole maʻalahi e haki, kūpaʻa kemika maikaʻi, kūpono no nā ʻano ʻōpala lāʻau wai a paʻa paha. Loaʻa iā ia ka pale maikaʻi no nā kukuna ultraviolet. ʻAʻawahia: ʻaʻohe ʻawahia.
ʻO ka ʻōmole palaki PET ka mea nui o ka hoʻopili ʻana i nā mea inu. ʻO ke kūlana koʻikoʻi ma ka ʻoihana hoʻopili mea inu ma Kina, ʻo ia nā ʻōmole palaki PET, a hiki i kēia manawa, ʻaʻohe mea ʻoi aku ka maikaʻi a ʻoi aku ka maikaʻi o ka ʻeke e pani i nā ʻōmole palaki PET. ʻO nā ʻōmole PP he hoʻokahi ʻanuʻu ka puhi ʻana i ka hoʻopili ʻana i hoʻokahi ʻanuʻu a me ʻelua ʻanuʻu ka puhi ʻana i ka hoʻopili ʻana i nā ʻōmole PP. Loaʻa i ka mīkini hoʻoheheʻe i ka hoʻopili ʻana i nā ʻōmole PP nā pono o ke aniani, paʻa, pale wela, a he haʻahaʻa hoʻi ke kumukūʻai.

ʻOi aku ka maikaʻi o ke kūpaʻa wela o nā ʻōmole palaki PP, ʻoi aku ka maʻalahi o ke ʻano o ka ʻōmole, palekana, hoʻomaʻemaʻe a me ka mālama ʻana i ka ʻono o nā mea i loko, ʻoi aku ka haʻahaʻa o ke kumukūʻai ma mua o PET, PS, PE a me nā mea ʻē aʻe. ʻO nā ʻōmole palaki PP i ka mākeke hoʻopili mea inu i ka hoʻohana ʻana i ke anakahi ua hoʻokokoke mālie i nā ʻōmole PET, nā resins i hoʻololi ʻia, nā mea hoʻonui permeability, a me nā mākau mīkini a me nā lako mai kēlā manawa a i kēia manawa e hana i ka hoʻomohala ʻana o nā ipu PP hiki ke pani i ke aniani, PET a me nā ipu PVC, ke ulu nei ka māhele mākeke.

Loaʻa i nā mea PP a me PET ko lākou mau pono a me nā ʻano ponoʻī, ʻaʻohe maikaʻi a maikaʻi ʻole paha, hilinaʻi nui ia i nā pono pilikino a me ka hoʻohana ʻana i ke kūlana e hoʻoholo ai, inā hoʻohana pinepine ʻia i nā mahana kiʻekiʻe, hiki iā ʻoe ke koho i ka mea PP. ʻO ka mea i luna ka loiloi o PP.nā kīʻaha palakia me nā kīʻaha palaki PET, lana koʻu manaʻo e hiki iā ia ke kōkua iā ʻoe.
