Summary of Standard Test Methods for Metal Coating on Electroplated Coils of Electric Heating Tubes

Summary of Standard Test Methods for Metal Coating on Electroplated Coils of Electric Heating Tubes

European tus qauv EN13523 yog tsim los ntawm Technical Committee CEN / TC139 ntawm Txheej thiab Varnishes, nrog DIN ua nws tus tuav ntaub ntawv. Txoj kev kuaj rau cov organic coatings ntawm dov hlau substrates yog teev. Feem ntau suav nrog: txheej thickness, daim iav gloss, xim sib txawv - ntsuas kev sib piv, pom kev sib piv, cwj mem hardness, tsis kam mus rau sai deformation (impact test), indentation adhesion (cupping test), tsis kam bending cracking (T-bend test), ntsev tsuag tsis kam, dej immersion tsis kam, tsis kam mus rau fluorescent UV lub teeb linearity thiab dej txias, hnyav tsis kam (wiping test), khawb tsis kam, tsis kam mus ceev aging (txoj kev cua sov), pulverization (Helmen method) Hnav tsis kam, peelability, adhesion ntawm txheej zaj duab xis, Kev ua qias tuaj, tsim qauv thiab cov qauv qauv rau kev sim ntsuas huab cua, kev ntsuam xyuas ntawm sab nraum zoov raug cov qauv, adhesion resistance thiab indentation test, thiab lwm yam.

1 Cov ntaub ntawv txheem

Cov qauv no muab cov kev cai ntawm lwm yam kev tshaj tawm nrog lossis tsis muaj hnub. Cov qauv no raug xa mus rau hauv qhov chaw tsim nyog hauv cov ntawv nyeem thiab cov ntawv tshaj tawm tau teev tseg tom qab ntawd. Kev xa mus rau cov ntawv sau hnub tim, kev hloov kho tom ntej, lossis kev hloov kho rau ib qho ntawm cov ntawv tshaj tawm no tsuas yog siv rau European Standard no thaum lawv muab tso rau hauv. Rau cov ntaub ntawv tsis raug txheeb xyuas, qhov tseeb version (nrog rau kev hloov kho) ntawm cov ntawv tshaj tawm cuam tshuam siv.

2 Cov ntsiab lus thiab cov ntsiab lus

2.1 Txheej hom

(1) Cov coatings tau los ntawm kev siv cov kua lossis hmoov txheej muaj cov zaj duab xis qhuav tuab txog 60 μ m.

(2) Coatings tau los ntawm daim ntawv thov ntawm cov kua los yog hmoov txheej, nrog ib tug qhuav zaj duab xis thickness ntau tshaj 60 μ m. Los yog laminated yas zaj duab xis.

2.2 Txheej

Ib txheej txuas ntxiv ntawm cov ntaub ntawv txheej tau los ntawm ib qho kev tsim kho.

2.3 Cov ntaub ntawv txheej

Ib yam khoom hauv daim ntawv ntawm cov kua, slurry, los yog hmoov, uas tsim ib zaj duab xis nrog kev tiv thaiv, zoo nkauj, thiab / los yog lwm yam ntxwv thaum siv rau lub substrate.

2.4 Roll coated hlau

Cov hlau coated nrog cov khoom siv txheej (3.4) los ntawm txoj kev coil txheej.

2.5 Txheej ntawm coiled cov ntaub ntawv

Cov txheej txheem txheej txheem ntawm kev siv cov txheej txheem tsis tu ncua (3.4) rau cov hlau coils, uas tuaj yeem muab dov rov qab dua tom qab txheej txheej zaj duab xis qhuav. Cov txheej txheem no suav nrog kev tu thiab / lossis kev kho mob ua ntej ntawm cov hlau nto, nrog rau kev ua kom cov kua lossis hmoov txheej tom qab ib los yog ntau txheej txheej ntawm ib lossis ob sab ntawm cov hlau yob, nrog rau lamination ntawm cov yeeb yaj kiab yas.

2.6 Organic txheej

Qhuav txheej zaj duab xis los yog yas zaj duab xis ntawm hlau laminated khoom uas tau coated.

2.7 Txheej

Cov ntaub ntawv txheej xim, hauv cov kua lossis slurry lossis hmoov daim ntawv, tsim cov opaque thiab tiv thaiv, zoo nkauj lossis cov yeeb yam yeeb yaj kiab thaum siv rau hauv substrate.

2.8 Kev tawm tswv yim

Tus nqi ntawm cov organic txheej tshem tawm tom qab txheej thiab tshem tawm daim kab xev.

2.9 Substrate

Qhov saum npoo coated los yog yuav tsum tau coated nrog cov ntaub ntawv txheej.

3 Sampling

Siv cov qauv tsim nyog ntawm qhov loj txaus los ntawm tag nrho cov dav yob coated hlau phaj los kuaj rau qhov kev xeem uas yuav tsum tau ua (tshwj tsis yog tau teev tseg).

4. Kev npaj cov qauv phaj

Npaj cov qauv xeem los ntawm cov qauv neeg sawv cev raws li tau piav qhia hauv Tshooj 4, thiab cov qauv xeem yuav tsum tiaj tus thiab qhov ntev tau teev tseg hauv cov qauv kev xeem tshwj xeeb (tshwj tsis yog hais qhia lwm yam).

5. Kev mob ntawm cov qauv kuaj

Cov qauv kuaj yuav tsum muab tso rau hauv chav tsev kub ua ntej kuaj.

Kev hloov ntawm cov qauv kuaj tsis yog feem ntau ua tiav. Yog tias muaj cov kev cai lossis cov xwm txheej tsis sib haum xeeb, raws li EN23270: 1991, cov qauv xeem yuav tsum tau kho tam sim ntawd thiab muab tso rau ntawm (23 ± 2) degree thiab txheeb ze av noo (50 ± 5) feem pua ​​​​rau tsawg kawg 24 teev ua ntej ua ntau yam kev xeem.

6 Cov xwm txheej xeem

Yog hais tias tus kheej txoj kev xeem tsis tau teev tseg nyias, kev sim (nrog rau kev ntsuas) yuav tsum tau ua nyob rau hauv chav tsev kub. Hauv cov xwm txheej tsis sib haum xeeb, raws li EN23270: 1991, qhov ntsuas kub tau teeb tsa ntawm (23 ± 2) degree thiab qhov txheeb ze av noo yog (50 ± 5) feem pua.
