Dab tsi yog cov txheej txheem tshuaj xyuas zoo rau galvanized steel hlau?
Txoj kev tshuaj xyuas zoo ntawm galvanized steel hlau feem ntau suav nrog cov hauv qab no:
1. Kev tshuaj xyuas qhov tshwm sim
Kev kuaj pom pom: Txheeb xyuas qhov sib xws, glossiness thiab muaj qhov tsis xws luag xws li npuas, tawg, thiab tev ntawm zinc txheej ntawm galvanized high carbon steel hlau.
2. Txheej thickness ntsuas
Txheej thickness gauge: Siv lub txheej thickness gauge (xws li ib tug sib nqus los yog eddy tam sim no thickness gauge) los ntsuas lub thickness ntawm zinc txheej ntawm lub galvanized hard drawn steel hlau los xyuas kom meej tias nws ua tau raws li tus qauv yuav tsum tau.
3. Adhesion xeem
Daim phiaj txoj kev: Kos ib daim phiaj ntawm zinc txheej ntawm galvanized tuab steel hlau, tom qab ntawd kaw nws thiab rub tawm sai sai los xyuas seb cov txheej puas tev tawm.
Pull-out test: Lub adhesion ntawm cov txheej ntawm pvc coated gi hlau rau lub substrate yog sim los ntawm kev siv lub zog tensile.
4. Corrosion resistance test
Kev kuaj ntsev ntsev: Muab cov galvanized gi fencing xaim rau hauv cov tshuaj tsuag ntsev kom simulate ib puag ncig corrosive thiab saib xyuas qhov kev tiv thaiv corrosion ntawm txheej.
Immersion test: Soak lub galvanized steel hlau nyob rau hauv ib qho nruab nrab corrosive los ntsuas nws corrosion kuj.
5. Tshuaj ntsuam xyuas muaj pes tsawg leeg
Kev tsom xam spectral: Txheeb xyuas cov tshuaj muaj pes tsawg leeg ntawm cov txheej txheem galvanized los ntawm spectrometer kom paub meej tias zinc cov ntsiab lus thiab lwm yam khoom ua tau raws li cov qauv.
Cov tshuaj muaj pes tsawg leeg ntawm galvanized txheej ntawm gi hlau loj 2.5 hli yog soj ntsuam los ntawm spectrometer los xyuas kom meej tias zinc cov ntsiab lus thiab lwm yam khoom raws li cov qauv.
6. Mechanical properties test
Tensile test: Ntsuas lub zog tensile thiab elongation ntawm cov hlau hlau kom paub meej tias nws cov khoom siv tau raws li qhov yuav tsum tau ua.
Bending test: Kuaj qhov toughness thiab plasticity ntawm cov hlau hlau thaum khoov.
7. Kev sim hardness
Rockwell hardness lossis Vickers hardness test: Ntsuas qhov hardness ntawm galvanized steel hlau los ntsuas nws qhov hnav tsis kam.
Los ntawm cov saum toj no-hais ntau yam kev ntsuam xyuas, cov khoom zoo ntawm txawv galvanized steel hlau hlua manufacturers tuaj yeem raug soj ntsuam xyuas kom ntseeg tau tias lawv cov kev ua tau zoo thiab kev nyab xeeb hauv kev siv tswv yim.
