Uhi manhole
hōʻike huahana:
ʻO ka paʻakikī maikaʻi. ʻO ka waiwai hopena e like me ke kila kalapona waena, ʻoi aku ia ma mua o 10 mau manawa o ka mea hao hina.
ʻO ke kūpaʻa ʻino ikaika. I ka hoʻāʻo ʻana i ka corrosion wai, ʻo ka nui o ka corrosion i nā lā 90 he 1/40 wale nō o ka paipu kila a me ka 1/10 o ka paipu hao hina. ʻO ke ola lawelawe he 2 mau manawa o ka paipu hao hina a me 5 manawa o ka paipu kila maʻamau.
ʻO ka plasticity maikaʻi. Elongation ≥7%, e like me ke kila kalapona kiʻekiʻe, akā ʻo ka elongation mea hao hina he zero.
ʻO ka ikaika kiʻekiʻe.ʻO ka ikaika tensile ob ≥420MPa a me ka hoʻouluʻana i ka ikaika OS ≥300MPa e like me ke kila kalapona haʻahaʻa aʻekolu manawa e like me ka mea hao hina.
Ma muli o kāna microstructure graphite nodular, ʻoi aku ka maikaʻi o ka hao ductile ma mua o ka hoʻolei ʻana i ke kila i ka hōʻemi ʻana i ka mana vibration, no laila ʻoi aku ka maikaʻi o ka hoʻemi ʻana i ke kaumaha. ʻOi aku ka maikaʻi o kēia mea hao, ʻoi aku ka maikaʻi, a emi ke kumu kūʻai i ka mīkini.
ʻO ka ikaika o ka hao ductile e hoʻohālikelikeʻia me ke kila. ʻO ka hapa nui o nā noi municipal e like me ka wai, ka wai paʻakai, ka mahu, etc.
