Cov qauv zoo thiab cov qauv ntsuas ntawm cov ntsia hlau kauj yog qhov tseem ceeb txuas los xyuas kom meej qhov zoo thiab kev nyab xeeb ntawm cov khoom siv rooj tog. Cov hauv qab no yog cov ntsiab lus tshwj xeeb ntawm cov qauv zoo thiab cov qauv kev sim ntawm cov ntsia hlau kauj:
1. Cov qauv zoo
Cov qauv zoo ntawm cov ntsia hlau coil feem ntau suav nrog cov hauv qab no:
- Cov khoom siv kuaj: Cov khoom siv ntawm cov ntsia hlau kauj muaj qhov cuam tshuam ncaj qha rau nws qhov kev ua tau zoo. Cov ntaub ntawv muaj xws li carbon steel, stainless hlau, thiab lwm yam. Cov ntaub ntawv sib txawv yog tsim rau ntau qhov chaw thiab siv. Piv txwv li, stainless hlau coil rau tes muaj kev tiv thaiv corrosion zoo dua thiab tsim nyog rau kev tsim cov rooj tog sab nraum zoov.
- Kev tshawb nrhiav qhov loj me: Qhov loj ntawm cov ntsia hlau kauj yuav tsum ua raws li cov qauv hauv lub tebchaws lossis cov qauv qhia rau cov neeg siv khoom. Qhov no suav nrog cov tsis xws li qhov ntev thiab txoj kab uas hla ntawm cov ntsia hlau kauj. Qhov tseeb ntawm qhov loj me yog qhov tseem ceeb rau kev siv cov ntsia hlau coil.
- Kev ntsuam xyuas cov cuab yeej cuab tam: suav nrog kev sim tensile, kev sim hardness, thiab lwm yam, txhawm rau txheeb xyuas seb cov khoom siv ntawm cov ntsia hlau coil xws li lub zog thiab qhov hnyav ua tau raws li cov qauv kev cai.
- Kev sim tshuaj muaj pes tsawg leeg: Los ntawm kev ntsuam xyuas cov tshuaj muaj pes tsawg leeg ntawm cov hlau, nws tau ua kom ntseeg tau tias qhov zoo ntawm cov hlau ua tau raws li tus qauv yuav tsum tau ua, yog li ua kom cov khoom siv ntawm cov ntsia hlau coil.
2. Cov txheej txheem kuaj
Cov kev sim rau coil ntsia hlau feem ntau suav nrog cov hauv qab no:
- Kev tshuaj xyuas qhov muag: Tshawb xyuas qhov zoo li, gloss ntawm qhov chaw, thiab cov duab ntawm cov ntsia hlau nrog lub qhov muag liab qab kom pom tias lawv ua tau raws li cov qauv zoo.
- Mechanical Properties Test: Nrog rau kev sim tensile, hardness test, thiab lwm yam., txhawm rau xyuas seb cov khoom siv ntawm cov ntsia hlau kauj, xws li lub zog thiab tawv, ua tau raws li cov qauv kev cai.
- Kev sim tshuaj muaj pes tsawg leeg: Los ntawm kev ntsuam xyuas cov tshuaj muaj pes tsawg leeg ntawm cov hlau, qhov zoo ntawm cov hlau yog lav kom ua tau raws li tus qauv yuav tsum tau ua, yog li ua kom cov khoom siv ntawm cov ntsia hlau coil.
- Electroplating thickness test: Rau galvanized coil rau tes, electroplating thickness kuaj yuav tsum tau xyuas kom meej tias cov txheej txheem zoo raws li tus qauv.
Cov saum toj no yog cov ntsiab lus tseem ceeb ntawm cov qauv zoo thiab cov qauv kev sim rau cov ntsia hlau coil. Cov qauv thiab cov txheej txheem no yog tsim los xyuas kom meej qhov zoo thiab kev ua tau zoo ntawm cov ntsia hlau coil, yog li ua kom ntseeg tau qhov zoo thiab kev nyab xeeb ntawm cov khoom rooj tog.
