Hoʻokaʻawale ʻia nā plastics meaʻai i: PET (polyethylene terephthalate), HDPE (high density polyethylene), LDPE (low density polyethylene), PP (polypropylene), PS (polystyrene), PC a me nā ʻano ʻē aʻe.
PET (polyethylene terephthalate)
Nā hoʻohana maʻamau: nā ʻōmole wai mineral, nā ʻōmole inu kalapona, etc.
Hana ʻia nā ʻōmole wai minerala a me nā ʻōmole inu carbonated i kēia mea.ʻAʻole hiki ke hoʻohana hou ʻia nā ʻōmole inu no ka wai wela, a ʻo kēia mea he pale wela a hiki i 70°C.He kūpono wale ia no nā mea inu mehana a i ʻole ka hau, a hiki ke hoʻololi ʻia ke hoʻopiha ʻia me nā wai wela wela a wela paha, me nā mea ʻino i ke kanaka e kahe ana i waho.Eia kekahi, ua ʻike nā kānaka ʻepekema ma hope o 10 mau mahina o ka hoʻohana ʻana, hiki i kēia huahana plastik ke hoʻokuʻu i nā carcinogens i mea ʻawaʻawa i ke kanaka.
No kēia kumu, pono e hoʻolei ʻia nā ʻōmole inu i ka wā e pau ai a ʻaʻole hoʻohana ʻia i kīʻaha a i ʻole nā puʻi waihona no nā mea ʻē aʻe e pale aku i nā pilikia olakino.
Ua hoʻohana mua ʻia ʻo PET ma ke ʻano he fiber synthetic, a me ke kiʻiʻoniʻoni a me ka lipine, a i ka makahiki 1976 wale nō i hoʻohana ʻia i loko o nā hue inu.Ua hoʻohana ʻia ʻo PET ma ke ʻano he mea hoʻopiha i ka mea i kapa ʻia ʻo ka 'pole PET'.
ʻO ka'ōmole PET ka paʻakikī a me ka paʻakikī, he māmā (ʻo 1/9 wale nō i ka 1/15 o ke kaumaha o ka'ōmole aniani), maʻalahi ke lawe a hoʻohana, hoʻopau i ka ikehu i ka hanaʻana, a he mea hikiʻole ke hoʻololi,ʻaʻole hiki ke hoʻololi a kū'ē. i nā waikawa a me nā alkali.
I nā makahiki i hala iho nei, ua lilo ia i mea hoʻopihapiha hoʻopihapiha koʻikoʻi no nā mea inu carbonated, kī, wai huaʻai, ka wai inu i hoʻopaʻa ʻia, ka waina a me ka soy sauce, etc. , a ua hoʻohana nui ʻia nā mea inu ʻona i loko o nā hue ʻeke.
HDPE(Polyethylene Māmā Kiʻekiʻe)
Hoʻohana maʻamau: nā mea hoʻomaʻemaʻe, nā huahana ʻauʻau, etc.
ʻO nā ipu plastik no ka hoʻomaʻemaʻe ʻana i nā huahana, nā huahana ʻauʻau, nā ʻeke plastik i hoʻohana ʻia i nā hale kūʻai nui a me nā hale kūʻai kūʻai i hana nui ʻia i kēia mea, hiki ke kū i ka 110 ℃ wela kiʻekiʻe, hōʻailona ʻia me nā ʻeke plastik meaʻai hiki ke hoʻohana ʻia e paʻa i ka meaʻai.Hiki ke hoʻohana hou ʻia nā ipu plastik no ka hoʻomaʻemaʻe ʻana i nā huahana a me nā huahana ʻauʻau ma hope o ka hoʻomaʻemaʻe pono ʻana, akā ʻaʻole i hoʻomaʻemaʻe maikaʻi ʻia kēia mau ipu, e waiho ana i nā koena o nā huahana hoʻomaʻemaʻe kumu, e hoʻohuli iā lākou i wahi hānau no ka bacteria a me ka hoʻomaʻemaʻe ʻole ʻana, no laila ʻoi aku ka maikaʻi ʻaʻole hana hou ia lakou.
ʻO PE ka plastic i hoʻohana nui ʻia i ka ʻoihana a me ke ola, a ua māhele ʻia i ʻelua ʻano: polyethylene high-density (HDPE) a me ka polyethylene haʻahaʻa haʻahaʻa (LDPE).He kiʻekiʻe ka helu heheʻe o HDPE ma mua o LDPE, ʻoi aku ka paʻakikī a ʻoi aku ke kūpaʻa i ka erosion o nā wai corrosive.
Loaʻa ka LDPE ma nā wahi a pau i ke ola o kēia wā, akā ʻaʻole no nā ipu i hana ʻia ai, akā no nā ʻeke plastik āu e ʻike ai ma nā wahi āpau.ʻO ka hapa nui o nā ʻeke plastik a me nā kiʻiʻoniʻoni i hana ʻia me LDPE.
LDPE (Polyethylene Haʻahaʻa Haʻahaʻa)
Hoʻohana maʻamau: pili kiʻiʻoniʻoni, etc.
ʻO ke kiʻiʻoniʻoni paʻa, ka kiʻiʻoniʻoni plastik, a me nā mea ʻē aʻe i hana ʻia i kēia mea.ʻAʻole ikaika ka pale ʻana i ka wela, ʻo ka mea maʻamau, ʻike ʻia ke kiʻi ʻoniʻoni ʻoniʻoni PE i ka mahana o ka ʻoi aku o 110 ℃, e haʻalele i kekahi kino kanaka ʻaʻole hiki ke decompose i ka mea plastik.Eia kekahi, i ka wā e wela ai ka meaʻai i ke kiʻi ʻoniʻoni, hiki i ka momona o ka meaʻai ke hoʻopau maʻalahi i nā mea ʻino i loko o ke kiʻiʻoniʻoni.No laila, he mea nui e wehe mua i ka mea ʻiʻo mai ka meaʻai i loko o ka microwave.
PP (polypropylene)
Hoʻohana maʻamau: pahu ʻaina awakea microwave
Hana ʻia nā pahu ʻaina microwave me kēia mea, kū i ka 130 ° C a ʻaʻohe ʻike maopopo.ʻO kēia wale nō ka pahu plastik hiki ke hoʻokomo ʻia i loko o ka microwave a hiki ke hoʻohana hou ʻia ma hope o ka hoʻomaʻemaʻe akahele.
He mea nui e hoʻomaopopo i kekahi mau pahu microwave i hana ʻia me ka PP 05, akā ua hana ʻia ke poʻi me PS 06, ʻo ia ka ʻike maikaʻi akā ʻaʻole kūpaʻa i nā wela kiʻekiʻe, no laila ʻaʻole hiki ke waiho ʻia i loko o ka microwave me ka ipu.No ka ʻaoʻao palekana, e wehe i ka poʻi ma mua o ka waiho ʻana i ka ipu i loko o ka microwave.
Hiki ke ʻōlelo ʻia ʻo PP a me PE he mau kaikunāne ʻelua, akā ʻoi aku ka maikaʻi o kekahi mau ʻano kino a me ka mechanical ma mua o ka PE, no laila hoʻohana pinepine ka poʻe hana omole i ka PE e hana i ke kino o ka hue, a hoʻohana iā PP me ka ʻoi aku ka paʻakikī a me ka ikaika e hana i ka pāpale a paʻa. .
He kiʻekiʻe hoʻoheheʻe ʻia ʻo PP o 167 ° C a he pale wela, a hiki ke hoʻopaʻa ʻia kāna huahana.ʻO nā'ōmole maʻamau i hanaʻia mai ka PP he waiu soy a me nā'ōmole waiu laiki, a me nā'ōmole no 100% wai huaʻai maʻemaʻe, yoghurt, wai inu wai, nā mea waiu (e like me ka pudding), a me nā mea'ē aʻe. ʻO nā pahu holoi lole, nā hīnaʻi, nā hīnaʻi, a me nā mea'ē aʻe, ua hana nuiʻia mai ka PP.
PS (polystyrene)
Hoʻohana maʻamau: nā kīʻaha pahu noodle, pahu meaʻai wikiwiki
ʻO ka mea i hoʻohana ʻia no ka hana ʻana i nā kīʻaha noodle a me nā pahu meaʻai wikiwiki.He pale wela a me ke anu, akā ʻaʻole hiki ke waiho ʻia i loko o ka umu microwave e pale aku i ka hoʻokuʻu ʻana o nā mea kemika ma muli o nā wela kiʻekiʻe.ʻAʻole pono e hoʻohana ʻia no nā ʻakika ikaika (e laʻa me ka wai ʻalani) a i ʻole nā mea alkaline, no ka mea hiki ke hoʻoheheʻe ʻia ka polystyrene, ka mea ʻino i ke kanaka.No laila, pono ʻoe e pale i ka hoʻopili ʻana i nā meaʻai wela i nā pahu meaʻai wikiwiki e like me ka hiki.
He haʻahaʻa ka wai o ka PS a paʻa ke ʻano, no laila hiki ke hoʻoheheʻe ʻia, kaomi ʻia, extruded a i ʻole thermoformed.Hiki ke hoʻoheheʻe ʻia, kaomi ʻia, extruded a thermoformed.Hoʻokaʻawale ʻia ʻo ia ma ke ʻano he foamed a i ʻole ka puaʻa ʻole e like me ka mea i hana ʻia i ke kaʻina hana "foaming".
PCa me nā mea ʻē aʻe
Hoʻohana maʻamau: ʻōmole wai, ʻeke, ʻeke waiu
ʻO ka PC kahi mea i hoʻohana nui ʻia, ʻoi aku ka nui o ka hana ʻana i nā hue waiu a me nā kīʻaha ākea, a he mea hoʻopaʻapaʻa no ka mea aia i loko o Bisphenol A. Hōʻike ka poʻe loea i ka manaʻo, ʻoiai ʻo ka BPA he 100% i hoʻololi ʻia i loko o ka hale palaki i ka wā o ka hana ʻana. PC, 'o ia ho'i, 'a'ole i ho'oku'u 'ia ka huahana.Eia nō naʻe, inā ʻaʻole i hoʻololi ʻia kahi helu liʻiliʻi o ka BPA i loko o ka ʻōnaehana plastik o PC, hiki ke hoʻokuʻu ʻia i loko o ka meaʻai a i ʻole nā mea inu.No laila, pono e mālama pono i ka wā e hoʻohana ai i kēia mau ipu plastik.
ʻO ke kiʻekiʻe o ka mahana o PC, ʻoi aku ka nui o ka BPA i hoʻokuʻu ʻia a ʻoi aku ka wikiwiki.No laila, ʻaʻole pono e lawelawe ʻia ka wai wela i loko o nā hue wai PC.Inā he helu 07 kāu ipu hao, hiki i kēia mau mea ke hōʻemi i ka pilikia: Mai wela ia i ka wā e hoʻohana ʻia ai a mai hōʻike i ka lā.Mai holoi i ka ipuhao i loko o ka mea holoi kīʻaha a mea holoi ipu paha.
Ma mua o ka hoʻohana ʻana iā ia no ka manawa mua, holoi ʻia me ka soda baking a me ka wai mehana a hoʻomaloʻo maoli i ka lumi wela.Pono e ho'ōki i ka hoʻohana ʻana i ka ipu inā he hāʻule a haki paha, no ka mea, hiki i nā huahana plastik ke hoʻopaʻa maʻalahi i ka maʻi bacteria inā loaʻa iā lākou kahi pitted maikaʻi.E hōʻalo i ka hoʻohana pinepine ʻana i nā ipu plastik i ʻino.
