I-ASTM A153 ne-ASTM A123 zingamazinga amabili ahlukene athuthukiswe yi-American Society for Testing and Materials (ASTM International), ikakhulukazi ahlobene nokucaciswa kwensimbi. Okulandelayo ukufana nokuhluka kwazo okuyinhloko:
Ukufana:
Indawo okuqondiswe kuyo: Kokubili kuhilela ukugqugquzelwa kwediphu eshisayo, okubandakanya ukucwiliswa kwemikhiqizo yensimbi ku-zinc encibilikisiwe ukuze kwakheke isivikelo se-zinc.
Umehluko:
Ububanzi obusebenzayo:
I-ASTM A153: Ifaneleka kakhulu i-hot-dip galvanizing yezingxenye ezincane, amabhawodi, amantongomane, izikulufu, njll. ezisetshenziswa emikhiqizweni ehlukahlukene.
I-ASTM A123: Isebenza kakhulu ezakhiweni ezinkudlwana noma ezibaluleke kakhulu, njengamapayipi, okokufakwayo, izindonga zokugada, izakhiwo zensimbi, njll., ezinezidingo eziqinile zongqimba lwazo lwezinc.
Ubukhulu be-coating:
I-ASTM A153: Isambatho esidingekayo ngokuvamile sincane futhi sivame ukusetshenziselwa izingxenye ezinezidingo eziphansi zokumelana nokugqwala.
I-ASTM A123: Izidingo zokumboza ngokuvamile ziqinile, zidinga ukujiya okukhudlwana ukuze kunikeze impilo ende yokumelana nokugqwala.
Indlela yokuthola:
I-ASTM A153: Indlela yokuhlola esetshenzisiwe ilula uma kuqhathaniswa, ikakhulukazi ehilela ukuhlolwa okubonakalayo kanye nesilinganiso sobukhulu bokunamathela.
I-ASTM A123: Iqine kakhulu, ngokuvamile ehlanganisa ukuhlaziywa kwamakhemikhali, ukuhlola okubonakalayo, ukukalwa kogqinsi lwe-coating, njll.
Inkambu yohlelo lokusebenza:
I-ASTM A153: Ifanele izingxenye ezithile ezincane, amabhawodi, amantongomane, njll.
I-ASTM A123: Ifanele izakhiwo ezinkulu nezibaluleke kakhulu, njengezakhiwo zokwakha, amabhuloho, ama-guardrails, njll.
Sekukonke, ukukhetha ukuthi iyiphi indinganiso ongayisebenzisa kuncike ezidingweni ezithile zohlelo lokusebenza. Uma izakhiwo ezinkudlwana zihilelekile noma zidinga ukumelana nokugqwala okuphakeme, kuvame ukukhethwa ukufakwa okushisayo kwediphu ngokuhambisana nezinga le-ASTM A123.
