Hoʻomaopopo i nā kumu kumu
ʻO Bisphenol a (BPA) a me Bisphenol F (BPF)ʻelua mau mea nui e like me nāʻoihana'ē aʻe e like me ka ikaika. ʻOiai e hoʻokaʻawale i kekahi mau mea like, aia nāʻokoʻaʻokoʻa ma waena o BPA a me BPF, kahi hiki i ka hopena o ka huahana epoxote o ka huahana epoxote.
He aha kaʻokoʻa?
ʻO kaʻokoʻa mua ma waena o BPA a me BPF e waiho ana i ko lākouʻano chemika. Aiaʻo BPAʻelua mau pūʻulu Isopropylideneʻelua e pili ana i nā pūʻulu phenolʻelua,ʻoiai he bpfʻelua mau pūʻulu phenolsne. ʻO kēia mau hopena liʻiliʻi e like me nā hualoaʻa liʻiliʻi liʻiliʻi i nāʻano likeʻole a me nā hiʻohiʻona hana:
•ʻO nā resins bpa epoxy e hōʻike i ka nui o ka hoʻouluʻana i keʻano e hoʻohālikelikeʻia i nā hoʻopakele epoxy bpf. ʻO kēia ke kumu e hiki ai i nā noho BPA - ke kūleʻa o BPA i ka wikiwiki a ma nā haʻahaʻa haʻahaʻa.
• ka uila:ʻO BPF Epoxy Resins eʻoi aku ka wikiwiki ma mua o nā mea e kūpono ai nā bpa epoxy, e hana ana i nā noi i koiʻia a me ka hopena hopena.
• nā kumuwaiwai:ʻO BPA epoxy resins e hāʻawi pinepine i nā mea maikaʻi loa a me ke kiʻekiʻe o ke aniani o ke aniani.
• Ke kumu:ʻO BPA epoxy e koho i nā kumukūʻai maʻamau ke kumukūʻai e hana ai i nā mea i hoʻohālikelikeʻia i nā hope o BPF epoxy.
Noi
ʻO BPAʻelua a me BPF Epoxy Resonsins e loaʻa i ka hoʻohana nuiʻana i nāʻano o nāʻoihana, e like me:
• Nā Kānāwai:ʻO nā mea epoxy e pili ana i ka bpa a me bpf e hoʻohanaʻia e pale ai i nā papa mai nā corrosio, abrasition, a me ka hoʻouka kauaʻana.
• Nā'ōkuhi:Ua hanaʻo EPOXY ADHESSIONS mai BPA a me BPF i hanaʻia ma ka waihoʻana i kahi nui o nā mea waiwai, mai nā plastics.
• Nā'ōnaehana:Hoʻohanaʻia nāʻano o nā pale o nā epoxy i nā matrices i nā mea hoʻohuihui e like me nā mea e pili ana i nā flaberglass a me nā noi carbolana ma ka mau noi.
• nā uila a me nā uila:Hoʻohanaʻia nā resins epoxy e like me ka insulating nā mea i nā'āpana uila a me nā papa helu circuit i paʻiʻia.
Nā hopohopo kūlohelohe a me nā koho'ē aʻe
I nā makahiki i hala iho nei, ua ulu nui ka hopohopo e pili ana i nā hopena olakino e hiki mai ana i nā hopena olakino o BPA, e alakaʻi ana i nā lula a me nā palena i kona hoʻohanaʻana i kekahi mau huahana. No laila, aia nō he shift i ka hoʻohanaʻana i ka hoʻohanaʻana o nā koho BPA Eia nō naʻe, he mea nui ia e hoʻomaopopo i keʻano o BPF ma mua o ka mea maʻamau ma mua o BPA, e loaʻa ana kekahi mau olakino olakino.
Ke kohoʻana i ka epox kūpono
ʻO ke koho o BPA a iʻole BPF epoxy Resin e hilinaʻi i nā koi kiko'ī o ka noi. ʻO nā mea e noʻonoʻo ai i nā mea:
• Nā waiwai hana:Pono ikaika, paʻakikī, pale pale, a me ka paʻaʻole.
• Ke kumu:ʻO ke kumukūʻai holoʻokoʻa o ka epoxy resin a me nā uku hana pili pili pili.
• Hoʻomanaʻo kaulike:Adtherence e pili ana i nā kānāwai kūpono a me nā hoʻoponopono palekana.
• E Sustaintability:Ka hopena o ke kaiāulu o ka epoxy resin a me kāna kaʻina hana hana.
Hopena
ʻO BPAʻelua a me BPF Epoxy Resonsins e hāʻawi i nā waiwai kūʻokoʻa a me nā mea waiwai, e hana ana iā lākou i nā mea waiwai nui ma nāʻoihana'ē aʻe. ʻOiaiʻo BPA i koho nuiʻia no nā makahiki he nui, e pili ana i kona mau hopena olakino e alakaʻi i ka makemake nui a me nā koho'ē aʻe. Ma ka noʻonoʻo ponoʻana i nā koi kiko'ī o kahi noi, hiki i nā mea hana a me nā mea hana ke koho i ka mea kūpono loa e hiki ai ke hoʻokō i nāʻano hana kūpono loa.
