Qhov txawv ntawmpre-galvanized yeeb nkabthiabKub-DIP Galvanized Steel Yeeb Nkab
1. Qhov txawv ntawm cov txheej txheem: Kub-dip galvanized yeeb nkab yog galvanized los ntawm immersing cov yeeb nkab steel hauv molten zinc, whereaspre-galvanized yeeb nkabyog tusyees coated nrog zinc rau saum npoo ntawm cov hlau sawb los ntawm cov txheej txheem electroplating.
2. Cov qauv sib txawv: Kub-dip galvanized yeeb nkab yog cov khoom siv tubular, thaum pre-galvanized steel yeeb nkab yog cov khoom siv sawb nrog qhov dav dav thiab me me thickness.
3. Cov kev siv sib txawv: cov kav dej kub galvanized feem ntau yog siv rau kev thauj cov kua thiab cov pa roj, xws li cov kav dej, cov kav dej, thiab lwm yam, thaum cov kav dej ua ntej galvanized steel feem ntau yog siv los tsim ntau yam khoom siv hlau, xws li cov khoom siv tsheb, hauv tsev. cov khoom siv plhaub thiab lwm yam.
4. Cov kev ua haujlwm sib txawv ntawm kev tiv thaiv corrosion: kub-dip galvanized yeeb nkab muaj kev ua haujlwm zoo dua los tiv thaiv corrosion vim cov txheej tuab galvanized, thaum galvanized steel sawb muaj kev ua haujlwm tsis zoo los tiv thaiv corrosion vim cov txheej txheej thinner galvanized.
5. Cov nqi sib txawv: cov txheej txheem ntau lawm ntawm cov yeeb nkab kub-dip galvanized yog qhov nyuaj thiab raug nqi, thaum cov txheej txheem ntawm cov yeeb nkab steel galvanized yog qhov yooj yim thiab tus nqi qis.
Kev tshuaj xyuas ntawm pre-galvanized thiab kub-dip galvanized steel yeeb nkab zoo
1. Kev tshuaj xyuas qhov tshwm sim
Nto tiav: Kev tshuaj xyuas qhov tshwm sim feem ntau yog kev txhawj xeeb txog seb qhov chaw ntawm cov yeeb nkab steel yog tiaj tus thiab du, tsis muaj zinc slag, zinc qog, ntws dai lossis lwm yam tsis xws luag. Zoo galvanized steel yeeb nkab nto yuav tsum du, tsis muaj npuas, tsis muaj kab nrib pleb, tsis muaj zinc hlav los yog zinc ntws dai thiab lwm yam tsis xws luag.
Xim thiab uniformity: xyuas seb cov xim ntawm cov yeeb nkab steel puas zoo ib yam, thiab seb puas muaj qhov sib npaug ntawm cov zinc txheej, tshwj xeeb tshaj yog nyob rau hauv seams los yog welded cheeb tsam. Kub-dip galvanized steel yeeb nkab feem ntau zoo li silvery dawb los yog tawm-dawb, thaum pre-galvanized steel yeeb nkab tej zaum yuav sib zog me ntsis xim.
2. Zinc thickness ntsuas
Thickness Gauge: Lub thickness ntawm zinc txheej yog ntsuas los ntawm ib tug coated thickness gauge (xws li sib nqus los yog eddy tam sim no). Qhov no yog qhov taw qhia tseem ceeb los txiav txim siab seb cov zinc txheej puas ua tau raws li tus qauv yuav tsum tau ua. Kub-dip galvanized steel yeeb nkab feem ntau muaj cov zinc txheej tuab, feem ntau ntawm 60-120 microns, thiab pre-galvanized steel yeeb nkab muaj ib txheej zinc txheej, feem ntau ntawm 15-30 microns.
Qhov hnyav txoj kev (sampling): Cov qauv yog ntsuas raws li tus qauv thiab qhov hnyav ntawm zinc txheej hauv ib chav tsev yog xam los txiav txim qhov tuab ntawm zinc txheej. Qhov no feem ntau yog txiav txim los ntawm kev ntsuas qhov hnyav ntawm cov yeeb nkab tom qab pickling.
Cov qauv yuav tsum tau muaj: Piv txwv li, GB / T 13912, ASTM A123 thiab lwm yam qauv muaj cov kev cai meej rau cov tuab ntawm zinc txheej, thiab zinc txheej thickness yuav tsum tau rau cov kav hlau rau cov ntawv sib txawv yuav txawv.
3. Uniformity ntawm galvanized txheej
Cov txheej txheem zoo galvanized yog ib yam hauv kev ntxhib los mos, tsis muaj to thiab tsis muaj kev puas tsuaj tom qab plating.
Tsis muaj liab ooze yog pom tom qab kuaj nrog tooj liab sulfate tov, qhia tias tsis muaj to los yog tom qab plating puas.
Qhov no yog tus qauv rau cov khoom siv zoo galvanized los xyuas kom meej qhov kev ua tau zoo thiab cov tsos.
4. Muaj zog adhesion ntawm galvanized txheej
Lub adhesion ntawm galvanized txheej yog ib qho tseem ceeb qhia txog qhov zoo ntawm galvanized steel yeeb nkab, uas qhia txog cov degree ntawm solidity ntawm kev sib txuas ntawm cov galvanized txheej thiab cov yeeb nkab steel.
Cov yeeb nkab steel yuav tsim ib txheej sib xyaw ntawm zinc thiab hlau nrog cov tshuaj galvanizing tom qab cov tshuaj tiv thaiv ntawm dipping da dej, thiab cov adhesion ntawm zinc txheej tuaj yeem txhim kho los ntawm kev tshawb fawb thiab cov txheej txheem galvanizing.
Yog tias cov zinc txheej tsis tuaj yeem tawm tau yooj yim thaum tapping nrog roj hmab mallet, nws qhia tau tias adhesion zoo.
