ʻAʻole hiki i nā plastik ke hoʻololi i nā mea metala, akā ʻoi aku ka nui o nā waiwai o nā plastics ma mua o nā alloys.A ua ʻoi aku ka hoʻohana ʻana o ka plastic i ka nui o ke kila, hiki ke ʻōlelo ʻia he pili pili loa i ko mākou ola.Hiki i ka ʻohana plastik ke waiwai a maʻamau i nā ʻano plastik ʻeono, e hoʻomaopopo kākou iā lākou.
1. Mea PC
Loaʻa i ka PC ke aniani maikaʻi a me ke kūpaʻa wela maʻamau.ʻO ka hemahema, ʻaʻole maikaʻi ia, ʻoi aku ka maikaʻi ma hope o ka manawa o ka hoʻohana ʻana, ʻike ʻia ke ʻano he "palapala", a he ʻenekini hoʻi ia, ʻo ia hoʻi, plexiglass, e like me ka polymethyl methacrylate., polycarbonate, etc.
ʻO PC kahi mea i hoʻohana nui ʻia, e like me nā hihia kelepona paʻa, laptops, a me nā mea ʻē aʻe, no ka hana ʻana i nā ʻōmole waiū, nā kīʻaha ākea, a me nā mea like.Ua hoʻopaʻapaʻa ʻia nā hue pēpē i nā makahiki i hala iho nei no ka mea he BPA.ʻO ke koena bisphenol A ma PC, ʻoi aku ka kiʻekiʻe o ka mahana, ʻoi aku ka hoʻokuʻu ʻana a me ka wikiwiki o ka wikiwiki.No laila, ʻaʻole pono e hoʻohana ʻia nā hue wai PC e paʻa i ka wai wela.
2. PP mea
ʻO ka plastik PP ka crystallization isotactic a loaʻa ka paʻa wela maikaʻi, akā palupalu ka mea a maʻalahi hoʻi e wāwahi, ʻo ka mea nui ka polypropylene.Hana ʻia ka pahu ʻaina awakea microwave i kēia mea, ʻaʻole i kū i ka wela kiʻekiʻe o 130 ° C a ʻaʻohe ʻike maopopo.ʻO kēia wale nō ka pahu plastik hiki ke hoʻokomo ʻia i loko o ka umu microwave a hiki ke hoʻohana hou ʻia ma hope o ka hoʻomaʻemaʻe akahele.
Pono e hoʻomaopopoʻia, no kekahi mau pahuʻaina awakea microwave, ua hanaʻia ka pahu pahu i ka helu 05 PP, akā ua hanaʻia ka poʻi i ka No. 06 PS (polystyrene).ʻO ka māmā o PS he awelika, akā,ʻaʻole ia e kū'ē i ka wela kiʻekiʻe, no lailaʻaʻole hiki ke hoʻohuiʻia me ke kino pahu.E hoʻokomo i loko o ka microwave.No ka ʻaoʻao palekana, e wehe i ka poʻi ma mua o ka waiho ʻana i ka ipu i loko o ka microwave.
3. PVC mea
ʻO PVC, i kapa ʻia ʻo PVC, he polyvinyl chloride resin, ka mea i hoʻohana pinepine ʻia e hana i nā profiles engineering a me nā huahana plastik ola i kēlā me kēia lā, e like me nā raincoats, nā mea kūkulu hale, nā kiʻiʻoniʻoni plastik, nā pahu plastik, a me nā mea ʻē aʻe.Akā hiki iā ia ke pale wale i ka mahana wela o 81 ℃.
ʻO nā meaʻawaʻawa a me nā meaʻino i hiki ke hanaʻia mai nāʻanoʻelua,ʻo kekahi ka monomolecular vinyl chloride i pihaʻole i ka polymerized i ka wā o ka hanaʻana, aʻo ka mea'ē aʻe nā meaʻino i loko o ka plasticizer.He maʻalahi kēia mau mea ʻelua ke hoʻoheheʻe i ka wā e hālāwai ai me ka wela kiʻekiʻe a me ka momona.Ma hope o ke komo ʻana o nā mea ʻawaʻawa i loko o ke kino o ke kanaka me ka meaʻai, ua maʻalahi ka maʻi kanesa.I kēia manawa, ʻaʻole hoʻohana ʻia nā pahu o kēia mea no ka hoʻopili ʻana i ka meaʻai.Eia kekahi, mai ʻae i ka wela.
4. PE mea
ʻO ka PE he polyethylene.ʻO ke kiʻiʻoniʻoni paʻa, ka kiʻiʻoniʻoni plastik, a me nā mea ʻē aʻe o kēia mau mea.ʻAʻole ikaika ka pale wela.ʻO ka mea maʻamau, e loaʻa kahi mea hoʻoheheʻe wela o ka PE plastic wrap i ka wā i ʻoi aku ka mahana ma mua o 110 ° C, e waiho ana i kekahi mau mea hoʻomākaukau plastik ʻaʻole hiki ke decomposed e ke kino kanaka.
Eia kekahi, i ka wā e wela ai ka meaʻai ma ke kāʻei ʻana i ka ʻili palaki, hiki i ka ʻaila i loko o ka meaʻai ke hoʻoheheʻe maʻalahi i nā mea ʻino i loko o ka ʻili plastik.No laila, i ka wā e hoʻokomo ʻia ai ka meaʻai i loko o ka umu microwave, pono e wehe mua ʻia ka ʻōpala i ʻōwili ʻia.
5. PET mea
ʻO PET, ʻo ia hoʻi, polyethylene terephthalate, nā ʻōmole wai mineral a me nā ʻōmole inu carbonated i hana ʻia i kēia mea.ʻAʻole hiki ke hana hou ʻia nā ʻōmole inu no ka mālama ʻana i ka wai wela.ʻAʻohe wela kēia mea a hiki i 70 ° C a kūpono wale ia no nā mea inu mehana a i ʻole ka hau.He mea maʻalahi ke hoʻololi ke hoʻopiha ʻia me ka wai wela a wela paha, a aia kekahi mau mea e hōʻino i ke kino o ke kanaka.
6. PMMA mea
ʻO ka PMMA, ʻo ia hoʻi, polymethyl methacrylate, i ʻike ʻia he acrylic, acrylic a plexiglass paha, ua kapa ʻia ʻo ia ka ikaika compressive ma Taiwan, a ua kapa pinepine ʻia ʻo agaric glue ma Hong Kong.Loaʻa iā ia ka māliko kiʻekiʻe, ke kumu kūʻai haʻahaʻa, a me ka maʻalahi machining.a me nā mea maikaʻi ʻē aʻe, he mea hoʻohana maʻamau ia i ke aniani pani pani.Akā ʻaʻole kiʻekiʻe kona kūpaʻa wela, ʻaʻohe mea ʻawaʻawa.Hoʻohana nui ʻia ia i ka ʻoihana hana logo hoʻolaha.
