1. Qhov tshwm sim ntawm cov kav dej galvanized
Yuav tsum muaj cov qauv zoo ntawm cov kav dej galvanized. Qhov saum npoo plating yog tiav thiab sib xws hauv cov xim. Tsis muaj dej ntws, qog qog, thiab qhov thaiv ntau dhau los xyuas kom tsis muaj qhov tsis zoo xws li xau plating thiab dew.
2. Dalvation txheej thickness
Lub thickness ntawm zinc txheej ntawm galvanized kav yog ib qho tseem ceeb qhia rau txiav txim qhov loj ntawm galvanizing. Feem ntau, chav tsev μM yog sawv cev los ntawm chav tsev μM, thiab qhov hnyav ntawm txheej galvanized ib square meter kuj tuaj yeem sawv cev los ntawm: 1g / m2=0.14 μm. Vim tias zinc thiab hlau muaj qhov sib nqus sib nqus thiab polarization, qhov tuab ntawm zinc txheej tuaj yeem txiav txim siab tias cov tuab ntawm zinc txheej tuaj yeem ntsuas los ntawm txheej txheej galvanized. Txhawm rau txiav txim siab qhov hnyav ntawm cov zinc txheej, nws yog ib qho tsim nyog yuav tsum tau khawb cov galvanized txheej sampling thiab ntsuas cov txheej txheem tshuaj xws li chloride chloride.
3. Uniformity ntawm galvanized txheej
Qhov zoo ntawm cov txheej txheem zoo galvanized yog ib yam, tsis muaj dej los yog tom qab plating puas. Tsis muaj kev tso dej liab tom qab kuaj los ntawm tooj liab sulfate tov, qhia tias nws tsis muaj qhov dej xau thiab kev puas tsuaj tom qab plating. Qhov no yog tus qauv rau cov kav dej zoo galvanized los xyuas kom meej tias nws cov kev ua tau zoo thiab cov tsos zoo tshaj plaws.
4. Kev nyiam ntawm galvanized txheej
Lub adhesion ntawm galvanized txheej yog ib qho tseem ceeb qhia txog qhov zoo ntawm galvanized steel kav. Nws qhia txog kev sib xyaw ua ke ntawm galvanized txheej thiab cov kav dej steel. Tom qab da dej cov tshuaj tiv thaiv, qhov saum npoo ntawm cov yeeb nkab steel yuav tsim cov zinc hlau sib xyaw txheej nrog cov kua galvanized. Los ntawm kev siv thev naus laus zis galvanized, qhov txuas ntawm zinc txheej tuaj yeem txhim kho. Siv cov roj hmab rauj yuav tsum tau tapping maj mam, cov zinc txheej tsis yooj yim kom poob tawm, qhia tias qhov adhesion zoo.
