No ke aha i hana ʻia ai nā pale kaʻa me ka plastic?
Pono nā hoʻoponopono e hōʻoia i nā mea pale mua a me hope o ke kaʻa ʻaʻole e hoʻopōʻino ka kaʻa i ke kaʻa i ka wā o ka hui ʻana o 4km/h. Eia kekahi, pale ka mua a me ka hope i ke kaʻa a hōʻemi i ka pōʻino o ke kaʻa i ka manawa like, akā pale pū i ka mea hele wāwae a hoʻemi i ka ʻeha i loaʻa i ka mea hele wāwae i ka wā e kū ai ka hui. No laila, pono e loaʻa i nā mea hale bumper nā ʻano penei:
1) Me ka paʻakikī o ka ʻili liʻiliʻi, hiki ke hōʻemi i ka ʻeha hele wāwae;
2) ʻO ka elasticity maikaʻi, me ka ikaika ikaika e pale i ka deformation plastic;
3) Maikaʻi ka ikaika damping a hiki ke hoʻonui i ka ikehu i loko o ka pae elastic;
4) Ke kū'ē i ka makū a me ka lepo;
5) Loaʻa iā ia ka waikawa maikaʻi a me ke kūpaʻa alkali a me ke kūpaʻa wela.
