Kub dip galvanizing yog ib qho txheej txheem hlau los tiv thaiv corrosion dav siv hauv cov khoom siv steel kom ntev lawv lub neej kev pab cuam thiab muab kev tiv thaiv zoo dua. ASTM (American Society for Testing and Materials) tau tsim ntau yam qauv los tsim cov txheej txheem thiab cov kev cai rau kev kub-dip galvanizing, nrog ASTM A153 thiab ASTM A123 yog ob tus qauv tseem ceeb. Cov hauv qab no yog qhov sib piv thiab qhov sib txawv ntawm ob tus qauv no:
ASTM A153 Cov Lus Qhia:
ASTM A153 Cov khoom lag luamyog tus qauv rau kub-dip galvanized steel hardware. Cov qauv no feem ntau siv tau rau cov hlau me me, xws li bolts, ceev, pins, screws,luj tshib,tees, reducers, etc.
1. Scope ntawm daim ntawv thov: Kub dip galvanizing rau me me hlau qhov chaw.
2. Zinc txheej thickness: Feem ntau, qhov tsawg kawg nkaus thickness ntawm zinc txheej yuav tsum tau. Feem ntau hnav galvanized, muab zoo corrosion kuj.
3. Daim ntawv thov teb: Feem ntau siv nyob rau hauv ib puag ncig sab hauv tsev nrog cov kev cai qis rau kev tiv thaiv corrosion, xws li rooj tog, laj kab, khoom siv hauv tsev, thiab lwm yam.
4. Cov kev cai kub: Muaj cov kev cai rau qhov kub dip kub ntawm cov khoom sib txawv.
ASTM A123 Cov Lus Qhia:
Tsis zoo li ASTM A153, ASTM A123 tus qauv siv tau rau cov khoom siv loj loj,cov kav hlau, steel beams, thiab lwm yam.
1. Scope ntawm daim ntawv thov: Haum rau cov khoom siv loj, xws li cov khoom siv hlau, txuas hniav, cov kav dej, thiab lwm yam.
2. Zinc txheej thickness: Muaj qhov tsawg kawg nkaus yuav tsum tau rau cov txheej zinc coated, feem ntau muab cov zinc txheej tuab dua los muab kev tiv thaiv zoo dua.
3. Kev siv teb: Feem ntau siv rau sab nraum zoov thiab raug cov qauv hauv qhov chaw hnyav, xws li txuas hniav, kav dej, khoom siv sab nraum zoov, thiab lwm yam.
4. Durability: Vim muaj kev koom tes ntawm cov txheej txheem tseem ceeb dua, txheej txheej galvanized yuav tsum tau tiv taus lub sij hawm ntev ntawm corrosion thiab ib puag ncig erosion.
Kev sib piv thiab cov ntsiab lus:
1. Cov ntawv thov sib txawv: A153 yog qhov tsim nyog rau cov khoom me me, thaum A123 haum rau cov khoom loj dua.
2. Lub thickness thiab durability ntawm zinc txheej yog txawv: A123's zinc txheej yog tuab thiab ruaj khov dua, muab kev tiv thaiv ntau dua.
3. Kev sib txawv ntawm kev siv: A153 feem ntau yog siv nyob rau hauv tsev thiab tsis tshua muaj corrosion ib puag ncig, thaum A123 yog haum rau sab nraum zoov thiab siab corrosion ib puag ncig.
4. Cov kev cai kub thiab cov txheej txheem sib txawv me ntsis: Ob tus qauv muaj lawv tus kheej kub dip kub thiab cov txheej txheem yuav tsum muaj rau ntau qhov sib txawv thiab hom khoom.
Zuag qhia tag nrho, qhov sib txawv ntawm ASTM A153 thiab ASTM A123 feem ntau yog nyob rau hauv lawv qhov kev thov, zinc txheej thickness, kev siv ib puag ncig, thiab cov kev cai kav ntev. Raws li cov xwm txheej tshwj xeeb thiab cov kev xav tau, cov tuam ntxhab thiab cov kws tsim khoom yuav tsum xaiv cov qauv uas ua tau raws li cov kev xav tau los xyuas kom meej cov khoom zoo thiab kav ntev.
