Cov hlau nplaum muaj zog yog cov hlau nplaum tshwj xeeb uas muaj zog sib nqus thiab lub zog adsorption. Txhawm rau kom ntseeg tau tias qhov ua tau zoo thiab kev ua haujlwm ntawm cov hlau nplaum muaj zog ua tau raws li cov qauv, yuav tsum tau kuaj xyuas nruj. Cov hauv qab no yog ob peb txoj kev tshuaj xyuas zoo rau cov hlau nplaum muaj zog:
Magnetic detection: Magnetism yog ib qho ntawm cov khoom tseem ceeb ntawm cov hlau nplaum muaj zog. Los ntawm kev siv lub magnetometer lossis magnetic sensor, qhov sib nqus teb lub zog thiab kev sib nqus ntawm cov hlau nplaum tuaj yeem ntsuas. Qhov no tuaj yeem pab txiav txim siab seb cov hlau nplaum ua tau raws li qhov xav tau sib nqus. Magnetic adsorption force test: Lub zog adsorption ntawm cov hlau nplaum muaj zog yog qhov tseem ceeb ntawm nws qhov kev ua tau zoo. Lub adhesion quab yuam ntawm cov hlau nplaum muaj zog tuaj yeem ntsuas tau siv lub ntsuas magnetic tshwj xeeb lossis ntsuas. Txoj kev xeem tuaj yeem ntsuas ncaj qha rau qhov siab tshaj plaws adsorption quab yuam ntawm cov hlau nplaum thiab cov hlau phaj, lossis nws tuaj yeem ntsuas tau los ntawm kev ntsuas lub zog adsorption ntawm cov hlau nplaum thiab cov hlau nplaum.
Kev tshuaj xyuas qhov tshwm sim: Txheeb xyuas qhov zoo ntawm cov hlau nplaum los ntawm kev kuaj pom thiab kov, suav nrog qhov chaw tiaj tus, gloss, xim thiab cov duab, thiab lwm yam. Txhua qhov chaw tsis xws luag, tawg lossis txawv teb chaws tuaj yeem cuam tshuam rau kev ua haujlwm thiab kev ua haujlwm ntev ntawm cov hlau nplaum. Kev ntsuas qhov ntev: Nws yog ib qho tseem ceeb heev los ntsuas qhov ntev thiab qhov ntsuas geometric ntawm cov hlau nplaum muaj zog. Siv cov cuab yeej ntsuas (xws li calipers, micrometers) los ntsuas txoj kab uas hla, qhov siab thiab lwm qhov ntsuas qhov ntsuas ntawm cov hlau nplaum kom ntseeg tau tias nws ua tau raws li qhov yuav tsum tau ua. Kev tshuaj xyuas tshuaj muaj pes tsawg leeg: Cov hlau nplaum muaj zog feem ntau yog ua los ntawm ntau yam hlau thiab alloys. Los ntawm cov khoom siv tshuaj lom neeg tshuaj ntsuam xyuas, cov ntsiab lus ntawm ntau lub ntsiab lus hauv cov hlau nplaum tuaj yeem kuaj xyuas kom ntseeg tau tias nws cov tshuaj muaj pes tsawg leeg ua tau raws li tus qauv yuav tsum tau ua. Kev ntsuas kub ntawm cov yam ntxwv: Kev ua haujlwm ntawm cov hlau nplaum muaj zog tuaj yeem hloov pauv nrog kev hloov pauv ntawm qhov kub thiab txias. Los ntawm kev ntsuas tus yam ntxwv ntawm qhov ntsuas kub, qhov kev ua tau zoo ntawm cov hlau nplaum ntawm qhov sib txawv ntawm qhov kub thiab txias tuaj yeem ntsuas tau thiab nws qhov kev ua haujlwm kub zoo tuaj yeem txiav txim siab.
