ASTM A123 / A123M Cov Lus Qhia
Txheej Thickness / Nyhav nyob ntawm cov khoom siv thiab steel thickness
Ua tiav tas mus li, du, uniform
Cov tsos mob tsis muaj coated, hlwv, flux deposits thiab gross dross inclusions nrog rau tsis muaj zinc deposits hnyav uas cuam tshuam rau kev siv.
Kev ua raws li tag nrho cov txheej txheem yuav tsum muaj kev ua tau zoo thoob plaws hauv lub neej kev pabcuam ntawm galvanized steel
Cov txheej kub-dip galvanized yog npaj rau cov khoom tsim rau hauv lawv cov duab kawg uas yuav raug rau corrosive ib puag ncig. Thaum ib yam khoom tau kub-dip galvanized, ib qho ntxiv fabrication, uas tsis tshua muaj tshwm sim, tej zaum yuav muaj qhov tsis zoo rau kev tiv thaiv corrosion ntawm txheej. Cov qib txheej yog txhais raws li qhov xav tau ntawm cov txheej txheej thiab muab hauv microns. Tag nrho cov txheej thickness yuav tsum tau nyob rau hauv specification ASTM A123 / A123M, (Tables 1 thiab 2), yog yam tsawg kawg nkaus; tsis muaj qhov siab tshaj plaws txheej thickness yuav tsum tau nyob rau hauv specification.
Nyob rau hauv atmospheric ib puag ncig, lub sij hawm rau thawj txij nkawm ntawm kub-dip galvanized hlau yog ncaj qha proportional rau lub thickness ntawm kub-dip galvanized txheej. Nrog rau tag nrho lwm yam hloov pauv tau nyob tas li, qhov tuab ntawm zinc txheej, lub neej ntev ntawm txheej txheej. Lub hom phiaj ntawm kev ua tiav thiab kev pom zoo yog los xyuas kom meej tias tsis muaj coatings muaj teeb meem thaj chaw uas tsis muaj zinc lossis muaj qhov tsis xws luag uas yuav cuam tshuam rau kev siv cov khoom. Tsis tas li ntawd, cov txheej txheem yuav tsum muaj kev sib raug zoo thoob plaws hauv kev pabcuam ntawm cov kub-dip galvanized steel.
