4. Ua nāwaliwali nā mea maka BPA a me ka pā haʻalulu ECH, ʻaʻole lawa ke kākoʻo o ke kumukūʻai resin, e kali ka ʻoihana a ʻike i ka manaʻo ikaika, kahi helu liʻiliʻi o lalo e pono e hahai, ua kaupalena ʻia ka nui o ka hāʻawi ʻana i ka mākeke.
ʻO ka loiloi kumu: Ke nāwaliwali nei ke kikowaena o ka umekaumaha o nā mea maka bisphenol A a me ka epichlorohydrin, nāwaliwali ke kākoʻo kumu kūʻai o ka epoxy resin, ʻaʻole i loli ka noi o lalo, ʻaʻole maikaʻi ka nūhou mākeke, aia ka ʻoihana i ke ʻano kali-a-ʻike.

ʻO ka bisphenol A a me ka epichlorohydrin haʻalulu nāwaliwali, hoʻonāwaliwali hou ke kumu kūʻai o ka mokulele, ke kaumaha mau nei ka lewa o lalo, ʻaʻole lawa nā kauoha hou i ka mākeke, he liʻiliʻi wale nō o ka hahai ʻana, ua hōʻike mālie nā mea hana resin, piʻi ka manaʻo bearish akahele. I kēia manawa, ʻaʻohe alakaʻi maikaʻi ma ka mākeke nūhou ma ka mākeke, a ʻo ka resin epoxy wā pōkole e manaʻo ʻia e holo ma kahi ākea a nāwaliwali. Pono nō e hoʻolohe i ke ʻano o nā mea maka a me ka makemake o lalo.
