mea nui o ka wai
ʻO ka wai ke kumu o ke ola. Hiki i ka wai ke hoʻoikaika i ka metabolism kanaka, kōkua i ka hou, a hoʻoponopono i ka mahana o ke kino. Ua lilo ka wai inu i mea ola no na kanaka. I nā makahiki i hala iho nei, ua hoʻololi mau ʻia nā kīʻaha wai, e like me ke kīʻaha kaulana o ka Internet "Big Belly Cup" a me ka "Ton Ton Bucket" kaulana loa. ʻO ka "Big Belly Cup" i makemake nui ʻia e nā keiki a me ka poʻe ʻōpio ma muli o kona ʻano nani, ʻoiai ʻo ka hana hou o ka "Ton-ton Bucket" ʻo ia ka mea i hōʻailona ʻia ai ka ʻōmole me ka manawa a me ka wai inu wai unahi e hoʻomanaʻo ai i ka poʻe e inu wai i loko. manawa. Ma ke ʻano he mea inu wai nui, pehea ʻoe e koho ai i ke kūʻai ʻana?
Nā mea nui o nā kīʻaha wai kai
Ke kūʻai ʻana i kīʻaha wai, ʻo ka mea nui ka nānā ʻana i kāna mea, e pili ana i ka palekana o ke kīʻaha wai holoʻokoʻa. ʻEhā ʻano nui o nā mea ʻilika maʻamau ma ka mākeke: PC (polycarbonate), PP (polypropylene), tritan (Tritan Copolyester coplyester), a me PPSU (polyphenylsulfone).
1. Mea PC
ʻAʻole ʻawaʻawa ʻo PC ponoʻī, akā ʻaʻole kūpaʻa nā mea PC (polycarbonate) i nā wela kiʻekiʻe. Inā wela a hoʻokomo ʻia i loko o kahi ʻakika a i ʻole ka alkaline, e hoʻokuʻu maʻalahi ia i ka mea ʻawaʻawa bisphenol A. Hōʻike kekahi mau hōʻike noiʻi hiki i ka bisphenol A ke hoʻoulu i nā maʻi endocrine. ʻO ka maʻi maʻi, ka momona i hoʻokumu ʻia e nā maʻi metabolic, ka wā ʻōpio mua o nā keiki, a me nā mea ʻē aʻe paha e pili ana i ka bisphenol A. Nui nā ʻāina, e like me Kanada, ua pāpā i ka hoʻohui ʻana i ka bisphenol A i loko o ka ʻeke meaʻai i nā lā mua. Ua pāpā ʻo Kina i ka lawe ʻana mai a kūʻai aku i nā ʻōmole pēpē PC ma 2011.
Nui nā kīʻaha wai plastik ma ka mākeke i hana ʻia me PC. Inā koho ʻoe i ke kīʻaha wai PC, e ʻoluʻolu e kūʻai mai ia mai nā kahawai maʻamau e hōʻoia i ka hana ʻia e like me nā lula. Inā he koho kāu, ʻaʻole wau e ʻōlelo aku e kūʻai i kahi kīʻaha wai PC.
2.PP mea
ʻO ka polypropylene PP he kala ʻole, ʻaʻala ʻole, ʻaʻohe mea ʻawaʻawa, translucent, ʻaʻohe bisphenol A, a hiki ke puhi ʻia. He 165°C kona wahi hehee a e palupalu ma kahi o 155°C. ʻO ka pae wela o ka hoʻohana ʻana he -30 ~ 140 ° C. ʻO nā kīʻaha papa ʻaina PP ʻo ia wale nō ka mea plastik hiki ke hoʻohana ʻia no ka hoʻomehana microwave.
3.tritan mea
ʻO Tritan kekahi polyester kemika e hoʻonā i nā hemahema o nā plastics, me ka paʻakikī, ka ikaika hopena, a me ka hydrolytic stability. He kūʻokoʻa kemika, akaka loa, ʻaʻohe bisphenol A i loko o ka PC. Ua hala ʻo Tritan i ka palapala FDA (Food Contact Notification (FCN) No.729) o ka US Food and Drug Administration a ʻo ia ka mea i koho ʻia no nā huahana pēpē ma ʻEulopa a me ʻAmelika Hui Pū ʻIa.
4.PPSU mea
ʻO ka PPSU (polyphenylsulfone) mea he thermoplastic amorphous, me ke kūpaʻa kiʻekiʻe o ka wela o 0 ℃ ~ 180 ℃, hiki ke paʻa i ka wai wela, he kiʻekiʻe ka permeability a me ke kūpaʻa hydrolysis kiʻekiʻe, a ʻo ia ka mea hue keiki e hiki ke kū i ka sterilization. Loaʻa i ka bisphenol A.
No ka palekana iā ʻoe iho a me kou ʻohana, e ʻoluʻolu e kūʻai i nā hue wai mai nā kahawai maʻamau a nānā pono i ke ʻano o nā mea i ka wā e kūʻai ai.
Hana ʻia nā kīʻaha wai e like me "Big Belly Cup" a me "Ton-ton Bucket" i ka plastic. ʻO nā hemahema maʻamau o nā huahana plastik penei:
1. ʻO nā kiko like ʻole (loaʻa nā haumia): loaʻa ke ʻano o kahi kiko, a ʻo kona anawaena kiʻekiʻe kona nui ke ana ʻia.
2. Burrs: Nā ʻōpuʻu laina ma nā ʻaoʻao a i ʻole nā laina hui o nā ʻāpana plastik (maʻamau ma muli o ka hoʻoheheʻe maikaʻi ʻana).
3. Uea kala: ʻO ke kinoea i hana ʻia i ka wā e hoʻoheheʻe ʻia ai ka mea e ʻeleʻele ai ka ʻili o nā ʻāpana plastik (keʻokeʻo maʻamau). ʻO ka hapa nui o kēia mau kinoea
ʻO ia ka wai i loko o ka resin. Hoʻopili maʻalahi kekahi mau resins i ka makū, no laila pono e hoʻohui ʻia kahi kaʻina maloʻo ma mua o ka hana ʻana.
4. Bubbles: Hoʻokumu nā wahi kaʻawale i loko o ka plastic i nā ʻōpuʻu poepoe ma kona ʻili.
5. Deformation: Deformation o nā ʻāpana plastik i hana ʻia e nā ʻokoʻa koʻikoʻi o loko a i ʻole ka hoʻomaha maikaʻi ʻana i ka wā hana.
6. Ejection whitening: ʻO ka keʻokeʻo a me ka deformation o ka huahana i hoʻopau ʻia ma muli o ka hoʻokuʻu ʻia ʻana mai ka mold, maʻamau ke hana ʻia ma ka ʻaoʻao ʻē aʻe o ka bit ejection (mother mold surface).
7. Ka nele o nā mea waiwai: Ma muli o ka pōʻino o ka ʻōpala a i ʻole nā kumu ʻē aʻe, hiki i ka huahana i hoʻopau ʻia ke unsaturated a nele i nā mea.
8. Paʻi haʻihaʻi: Nā kiko keʻokeʻo i nā paʻi paʻi i hana ʻia e nā haumia a i ʻole nā kumu ʻē aʻe i ka wā e paʻi ai.
9. Nalo ka pa'i 'ana: Inā 'a'ole nalo ka ma'i'o i pa'i 'ia, 'a'ole nalo ka pa'i 'ana.
10. ʻOkoʻa kala: e pili ana i ka waihoʻoluʻu ʻāpana maoli a me ka waihoʻoluʻu hāpana i ʻae ʻia a i ʻole ka helu kala ma mua o ka waiwai ʻae.
11. Lae waihoʻoluʻu like: pili i ke kiko kahi kokoke i ke kala o ka ʻāpana; i ole ia, he kiko kala okoa.
12. Nā kaha kahe: ʻO nā kaha kahe o ka plastik hoʻoheheʻe wela i waiho ʻia ma ka ʻīpuka ma muli o ka hoʻoheheʻe ʻana.
13. Weld marks: Linear marks i hana ʻia ma ka ʻili o kekahi ʻāpana ma muli o ka hui ʻana o ʻelua a ʻoi aku paha nā kahawai plastik i hoʻoheheʻe ʻia.
14. ʻAha hui: Ma waho aʻe o ke āpau i hōʻike ʻia i ka hoʻolālā, ʻo ke āpau i hana ʻia e ka hui ʻana o nā ʻāpana ʻelua.
15. ʻO nā ʻōpala maikaʻi: nā ʻōpala a i ʻole nā hōʻailona me ka hohonu ʻole (maʻa mau ʻia e ka hana lima).
16. Nā ʻōpala paʻakikī: ʻO nā ʻōpala laina hohonu ma ka ʻili o nā ʻāpana i hana ʻia e nā mea paʻakikī a i ʻole nā mea ʻoi (e hana pinepine ʻia e nā hana lima).
17. ʻO ka niho a me ka emi ʻana: Aia nā hōʻailona o nā niho ma ka ʻili o ka ʻāpana a i ʻole ka liʻiliʻi o ka nui ma mua o ka nui o ka hoʻolālā (ʻo ka mea maʻamau ke kumu o ka hoʻoheheʻe ʻana).
18. Ka ho'oka'awale kala: I ka hana 'ilika, 'ike 'ia nā kaha a i 'ole nā kiko kala ma ka wahi kahe (ma muli o ka ho'ohui 'ana i nā mea hana hou).
19. ʻAʻole ʻike ʻia: ʻo ia hoʻi, ʻaʻole ʻike ʻia nā hemahema me ke anawaena ma lalo o 0.03mm, koe wale nō ka wahi alohilohi LENS (e like me ka mamao ʻike i kuhikuhi ʻia no kēlā me kēia ʻāpana mea).
20. Bump: ma muli o ka pā ʻana o ka ʻili a i ʻole ka ʻaoʻao e kekahi mea paʻakikī.
