ʻO ASTM A153 a me ASTM A123 ʻelua mau kūlana like ʻole i hoʻomohala ʻia e ka American Society for Testing and Materials (ASTM International), pili nui i ka kikoʻī o ke kila galvanized. Eia ko lakou mau like a me na mea like ole.
Nā mea like:
Wahi i hoʻopaʻa ʻia: Hoʻokomo ʻia nā mea ʻelua i ka galvanizing wela, kahi e hoʻokomo ai i nā huahana kila i loko o ka zinc hehee e hana i kahi uhi pale o ka zinc.
Nā ʻokoʻa:
Laulā kūpono:
ASTM A153: Maikaʻi no ka wela-dip galvanizing o nā ʻāpana liʻiliʻi, bolts, nuts, screws, etc. i hoʻohana ʻia i nā huahana like ʻole.
ASTM A123: Hoʻohana nui ʻia i nā hale nui a i ʻole nā mea koʻikoʻi, e like me nā paipu, nā mea pono, nā pale, nā hale kila, a me nā mea ʻē aʻe, me nā koi koʻikoʻi no kā lākou papa zinc.
Mānoanoa uhi:
ASTM A153: ʻO ka uhi maʻamau i koi ʻia he lahilahi a hoʻohana mau ʻia no nā ʻāpana me nā koi haʻahaʻa no ka pale ʻana i ka corrosion.
ASTM A123: ʻOi aku ka paʻakikī o nā koi no ka uhi ʻana, e koi ana i kahi mānoanoa uhi nui e hāʻawi i ke ola kūpaʻa ʻoi aku ka lōʻihi.
ʻAno ʻike:
ASTM A153: He mea maʻalahi ke ʻano hoʻāʻo i hoʻohana ʻia, e pili ana i ka nānā ʻana a me ke ana mānoanoa o ka uhi.
ASTM A123: ʻOi aku ke koʻikoʻi, maʻamau me ka nānā ʻana i nā kemika, ka nānā ʻana i ka ʻike, ke ana ʻana o ka mānoanoa o ka uhi, etc.
Kahua noi:
ASTM A153: He kūpono no kekahi mau mea liʻiliʻi, bolts, nuts, etc.
ASTM A123: He kūpono no nā hale nui a ʻoi aku ka nui, e like me nā hale kūkulu hale, nā alahaka, nā guardrails, etc.
Ma ke ʻano holoʻokoʻa, ʻo ke koho ʻana i ka maʻamau e hoʻohana ai e pili ana i nā koi noi kikoʻī. Inā pili nā hale nui a i ʻole ke koi ʻana i ke kūpaʻa corrosion kiʻekiʻe, koho maʻamau ka galvanizing hot-dip e like me ka maʻamau ASTM A123.
