ʻO ka hot dip galvanizing kahi hana anti-corrosion metala maʻamau i hoʻohana nui ʻia i nā huahana kila e hoʻonui i ko lākou ola lawelawe a hāʻawi i ka pale maikaʻi.Ua hoʻomohala ʻo ASTM (American Society for Testing and Materials) i nā maʻamau he nui e hoʻohālikelike i nā kaʻina hana a me nā koi no ka hot-dip galvanizing, me ASTM A153 a me ASTM A123 nā kumu nui ʻelua.Eia nā hoʻohālikelike a me nā ʻokoʻa ma waena o kēia mau maʻamau ʻelua.
ASTM A153:
ASTM A153he mea maʻamau no nā lako hao hao wela wela.Hoʻohana pinepine ʻia kēia maʻamau i nā ʻāpana hao liʻiliʻi, e like me nā bolts, nuts, pins, screws,kuʻekuʻe lima,tees, reducers, etc.
1. Ka laulā o ka noi: Hot dip galvanizing no nā ʻāpana metala liʻiliʻi.
2. ʻO ka mānoanoa papa Zinc: ʻO ka mea maʻamau, pono ka mānoanoa liʻiliʻi o ka papa zinc.ʻO ka galvanized māmā maʻamau, e hāʻawi ana i ka pale corrosion maikaʻi.
3. Ke kahua noi: Hoʻohana maʻamau i loko o nā kaiapuni i loko me nā koi haʻahaʻa no ka pale ʻana i ka corrosion, e like me nā lako, nā pā, nā lako hale, etc.
4. Nā koi wela: Aia nā lula no ka wela wela o nā mea like ʻole.
ASTM A123:
ʻAʻole like me ASTM A153, pili ka maʻamau ʻo ASTM A123 i nā ʻāpana kūkulu nui nui,paipu kila, kaola kila, etc.
1. Ka laulā o ka noi: He kūpono no nā ʻāpana kūkulu nui, e like me nā mea kila, nā alahaka, nā pipeline, etc.
2. ʻO ka mānoanoa papa Zinc: Aia kahi koi haʻahaʻa kiʻekiʻe no ka papa zinc i uhi ʻia, maʻamau e hāʻawi i kahi uhi zinc mānoanoa e hāʻawi i ka pale ikaika.
3. Ke kahua o ka hoʻohana: Hoʻohana maʻamau no nā hale o waho a i ʻike ʻia i nā wahi paʻakikī, e like me nā alahaka, nā pipeline, nā lako waho, etc.
4. ʻO ka lōʻihi: Ma muli o ke komo ʻana o nā mea hoʻolālā koʻikoʻi, pono ka papa galvanized e kū i nā wā lōʻihi o ka ʻino a me ka ʻino o ke kaiapuni.
Hoʻohālikelike a me ka hōʻuluʻulu manaʻo:
1. Nā pae noi like ʻole: Ua kūpono ʻo A153 no nā ʻāpana liʻiliʻi, ʻoiai ʻo A123 kūpono no nā ʻāpana kūkulu nui.
2. ʻOkoʻa ka mānoanoa a me ka lōʻihi o ka papa zinc: ʻOi aku ka mānoanoa a me ka lōʻihi o ka uhi zinc A123, e hāʻawi ana i kahi kiʻekiʻe o ka pale.
3. Nā kahua hoʻohana like ʻole: Hoʻohana maʻamau ʻia ʻo A153 i loko o ka hale a me ka haʻahaʻa haʻahaʻa haʻahaʻa, ʻoiai ʻo A123 e kūpono i nā wahi o waho a me ke kiʻekiʻe.
4. ʻOkoʻa ka ʻokoʻa o ka wela a me ke kaʻina hana: Loaʻa i nā maʻamau ʻelua kā lākou wela wela a me nā koi kaʻina no nā ʻano nui a me nā ʻano mea.
Ma ke ʻano holoʻokoʻa, aia ka ʻokoʻa ma waena o ASTM A153 a me ASTM A123 i kā lākou kiko o ka noi, ka mānoanoa zinc layer, ka hoʻohana ʻana, a me nā koi paʻa.E like me nā hiʻohiʻona hoʻohana kikoʻī a me nā koi, pono nā mea hana a me nā ʻenekinia e koho i nā kūlana e kūpono i nā pono kūpono e hōʻoia i ka maikaʻi o ka huahana a me ka lōʻihi.
