ʻOi aku ka maikaʻi o nā kīʻaha plastik i ka PP a i ʻole PET?

Nā kīʻaha iʻaHe 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 i ka wai wela, akā hiki ke hoʻopiha ʻia kekahi mau kīʻaha plastik i ka wai anuanu.I ka manawa like, e ʻokoʻa nā mea like ʻole i ka helehelena.ʻO ke ola a mākou e hoʻohana ai i nā kīʻaha plastik he mea maʻamau i hana ʻia me ka PP a me ka mea PET, nui ka poʻe e noho ma ke kīʻaha plastik he PP mea a i ʻole nā ​​​​mea PET maikaʻi i kēia pilikia e hopohopo?No kēia pilikia, ʻo ka make-up liʻiliʻi e pane aku nei iā ʻoe, e hui koke nā hoaaloha hoihoi e ʻike!
ʻO PP ka polypropylene, ʻo PET ka polyester.ʻO ka manaʻo ʻelua ʻaʻohe mea ʻawaʻawa, akā ma ke ʻano o ka pale ʻana i ka wā kahiko a me ka pale ʻana i ka wā, ʻoi aku ka maikaʻi o ka PP no nā kīʻaha wai, ʻoi aku ka maikaʻi o ka pale ʻana o ka wela, hiki ke kū i nā mahana kiʻekiʻe o 120 degere, ʻo ia wale nō ka mea i hoʻokomo ʻia i loko o ka pahu. microwave.

Nā noi Polypropylene (PP): nā kīʻaha microwave, nā ipu hao, nā bākeke plastik, nā pūpū thermos, nā ʻeke i ulana ʻia, a me nā mea ʻē aʻe.Hiki ke hoʻohana ʻia ka papa ʻaina microwave i hōʻailona ʻia i nā huahana plastik PP.ʻO ke kino: ʻaʻohe mea ʻawaʻawa, ʻaʻohe pōʻino i ke kino kanaka.Hiki i ka polymer ke loa'a i 'ekolu-dimensional structure: isometric, intergraphic, atactic polypropylene, hiki i na mea mua ke crystallize, aole hiki i ka hope.ʻO nā huahana polypropylene i loaʻa i nā mea kūʻai aku ke kumu o ka mākeke iso-gauge, ka helu heheʻe o 164 ~ 170 degere Celsius, ka ʻāpana crystalline o ka density o 0.935 grams / cubic centimeters, ka hapa maʻemaʻe ʻole o ka 0.851 grams / cubic centimeters.ʻO ka drawback nui o PP ʻo ia ka maʻalahi o ka oxidize a me ka makahiki.I kēia manawa me ka hoʻohui ʻana o nā antioxidants a me nā mea hoʻopau ultraviolet e lanakila ai.
Nā noi Polyester (PET): nā ʻōmole mea inu plastik, nā ʻōmole lāʻau lapaʻau, nā ʻōmole hoʻonaninani, nā ʻōmole ʻaila, a me nā ʻano o nā ʻōmole ʻōmole, uhi uhi.Nā hiʻohiʻona: ʻike maikaʻi maikaʻi, ʻaʻole maʻalahi e wāwahi, kūpaʻa kemika maikaʻi, kūpono no nā ʻano wai a i ʻole nā ​​​​lāʻau lāʻau paʻa.He pale maikaʻi kona no nā kukuna ultraviolet.Kaʻawaʻawa: non-toxic.
ʻO ka hue plastik PET ka mea nui o ka ʻeke inu.ʻO ke kūlana koʻikoʻi i loko o ka ʻoihana mea inu mea inu ʻo Kina e pono i nā ʻōmole plastik PET, a hiki i kēia manawa, ʻaʻohe mea ʻoi aku ka maikaʻi a ʻoi aku ka maikaʻi o nā mea i loaʻa e hoʻololi i nā hue plastik PET. ʻO ka mīkini hoʻoheheʻe i ka hoʻoheheʻe ʻana i nā hue PP i loaʻa nā pōmaikaʻi o ke aniani, paʻa, pale wela, a ʻoi aku ka haʻahaʻa o ke kumukūʻai.

ʻO nā ʻōmole plastik PP me ka ʻoi aku ka maikaʻi o ka wela, ke ʻano o ka huehue depiction sensitive, palekana, hoʻomaʻemaʻe a me nā mea i loko o ka ʻono o ka mālama ʻana i ka haʻahaʻa, ʻoi aku ke kumukūʻai ma mua o PET, PS, PE a me nā mea ʻē aʻe. i ka hoʻohana 'ana i ka unahi ua hele lohi i ka PET omole, hoʻololi resins, permeability enhancers, a me ka mīkini a me na lako akamai mai ka manawa i ka manawa e hana i ka hooulu ana o PP ipu hiki ke pani i ke aniani, PET a me ka PVC ipu, e ulu ana ka makeke.

Loaʻa i nā mea PP a me PET ko lākou pono ponoʻī a me nā hiʻohiʻona, ʻaʻohe maikaʻi a maikaʻi ʻole paha, e hilinaʻi nui ʻia 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 nā mea PP.ʻO ka mea i luna nei ka nānā ʻana o PPnā kīʻaha plastika me nā kīʻaha plastik PET, manaʻolana wau e hiki ke kōkua iā ʻoe.
