Hot dip galvanizing ndi njira yodziwika bwino yachitsulo yotsutsana ndi dzimbiri yomwe imagwiritsidwa ntchito kwambiri pazinthu zachitsulo kuti ziwonjezere moyo wawo wautumiki ndikupereka chitetezo chabwino.ASTM (American Society for Testing and Equipment) yapanga miyezo ingapo kuti ikhazikitse njira ndi zofunikira pakuyatsira moto wothira, ASTM A153 ndi ASTM A123 kukhala miyezo iwiri yayikulu.Zotsatirazi ndi kufananitsa ndi kusiyana pakati pa miyezo iwiriyi:
ASTM A153:
Chithunzi cha ASTM A153ndi muyezo kwa otentha-kuviika kanasonkhezereka zitsulo hardware.Muyezowu nthawi zambiri umagwiritsidwa ntchito pazigawo zing'onozing'ono zachitsulo, monga ma bolts, mtedza, mapini, zomangira,zigongono, tees, reducers, etc.
1. Kuchuluka kwa ntchito: Dip dip galvanizing pazigawo zing'onozing'ono zachitsulo.
2. Zinc wosanjikiza makulidwe: Nthawi zambiri, makulidwe ochepera a zinki amafunikira.Nthawi zambiri opepuka kanasonkhezereka, kupereka zabwino dzimbiri kukana.
3. Malo ogwiritsira ntchito: Amagwiritsidwa ntchito m'malo amkati omwe ali ndi zofunikira zochepa kuti asawonongeke, monga mipando, mipanda, zipangizo zapakhomo, ndi zina zotero.
4. Zofunikira za Kutentha: Pali malamulo a kutentha kwa kutentha kwa zinthu zosiyanasiyana.
ASTM A123:
Mosiyana ndi ASTM A153, muyezo wa ASTM A123 umagwira ntchito pazigawo zazikuluzikulu zamapangidwe,mapaipi achitsulo, matabwa achitsulo, etc.
1. Kuchuluka kwa ntchito: Yoyenera pazinthu zazikulu zamapangidwe, monga zigawo zachitsulo, milatho, mapaipi, ndi zina zotero.
2. Zinc wosanjikiza makulidwe: Pali chocheperako chocheperako chofunikira kwambiri pansanjika wokutidwa wa zinki, nthawi zambiri zimapereka zokutira zokulirapo kuti zitetezeke mwamphamvu.
3. Munda wogwiritsidwa ntchito: Zomwe zimagwiritsidwa ntchito panja ndi zowonekera m'madera ovuta, monga milatho, mapaipi, zipangizo zakunja, ndi zina zotero.
4. Kukhalitsa: Chifukwa cha kuphatikizidwa kwa zigawo zofunika kwambiri zamapangidwe, malata amafunikira kuti apirire kwa nthawi yayitali ya dzimbiri ndi kukokoloka kwa chilengedwe.
Kufananiza ndi Chidule:
1. Mitundu yosiyanasiyana yogwiritsira ntchito: A153 ndi yoyenera pazigawo zing'onozing'ono, pamene A123 ndi yoyenera pazigawo zazikulu zamagulu.
2. Makulidwe ndi kulimba kwa zinc wosanjikiza ndi zosiyana: A123's zokutira zinc ndi wandiweyani komanso cholimba, kupereka mlingo wapamwamba wa chitetezo.
3. Magawo osiyanasiyana ogwiritsira ntchito: A153 imagwiritsidwa ntchito kwambiri m'nyumba zamkati komanso zocheperako, pomwe A123 ndi yoyenera kumadera akunja komanso okhala ndi dzimbiri.
4. Zofunikira za kutentha ndi ndondomeko yosiyana pang'ono: Miyezo iwiriyi ili ndi kutentha kwake kotentha komanso zofunikira zamagulu osiyanasiyana ndi mitundu ya zinthu.
Ponseponse, kusiyana pakati pa ASTM A153 ndi ASTM A123 makamaka kwagona pakugwiritsa ntchito, makulidwe a zinc wosanjikiza, malo ogwiritsira ntchito, komanso zofunikira zolimba.Kutengera momwe amagwiritsidwira ntchito komanso zofunikira, opanga ndi mainjiniya amayenera kusankha milingo yomwe imakwaniritsa zofunikira kuti zitsimikizire mtundu wazinthu komanso kulimba.
