Qualicoat-Test Methods and Requirements

Cov txheej txheem Qualicoat-Test uas tau piav qhia hauv qab no yog siv los kuaj cov khoom tiav thiab / lossis txheej txheej rau kev pom zoo (saib tshooj 4 thiab 5).

Rau cov kev ntsuam xyuas tshuab (seem 2.6, 2.7 thiab 2.8), qhov kev xeem panels yuav tsum tau ua los ntawm alloy AA 5005-H24 los yog -H14 (AlMg 1 - semihard) nrog ib tug thickness ntawm 0.8 los yog 1 hli, tshwj tsis yog tias pom zoo los ntawm cov Technical Pawg neeg.
Kev ntsuam xyuas siv tshuaj thiab kev kuaj corrosion yuav tsum tau ua nyob rau hauv extruded seem ua los ntawm AA 6060 los yog AA 6063.

1. Tsos

Cov tsos mob yuav raug soj ntsuam ntawm qhov chaw tseem ceeb.
Qhov tseem ceeb ntawm qhov chaw yuav tsum tau txhais los ntawm cov neeg siv khoom thiab yog ib feem ntawm tag nrho cov saum npoo uas yog qhov tseem ceeb rau cov tsos thiab kev pabcuam ntawm cov khoom. Ntug, qhov tob tob thiab qhov chaw nruab nrab tsis suav nrog qhov tseem ceeb ntawm qhov chaw.Cov txheej txheem ntawm qhov tseem ceeb yuav tsum tsis txhob muaj khawb mus rau hauv lub hauv paus hlau. Thaum cov txheej txheej ntawm qhov tseem ceeb tau pom ntawm lub kaum sab xis ntawm 60 ° rau saum npoo, tsis muaj qhov tsis xws luag hauv qab no yuav tsum pom los ntawm qhov deb ntawm 3 meters: ntau dhau roughness, khiav, hlwv, suav nrog, craters, npub. pob, pinholes, pits, khawb lossis lwm yam tsis txaus ntseeg.
Cov txheej yuav tsum yog xim thiab gloss nrog kev tiv thaiv zoo. Thaum saib ntawm qhov chaw, cov qauv no yuav tsum ua kom tiav raws li hauv qab no:

• - rau cov khoom siv sab nraud: saib ntawm qhov deb ntawm 5 m
• - rau cov khoom siv sab hauv: saib ntawm qhov deb ntawm 3 m

2. Gloss

TS EN ISO 2813 Kev teeb pom kev zoo ntawm 60 ° rau qhov qub.
Nco tseg: yog tias qhov chaw tseem ceeb me dhau los yog tsis tsim nyog rau qhov gloss los ntsuas nrog lub glossmeter, lub gloss yuav tsum muab piv rau qhov pom ntawm cov qauv siv (los ntawm tib lub kaum sab xis saib).

YUAV TSUM TAU:

• Qeb 1: 0 - 30 +/- 5 units
• Qeb 2: 31 - 70 +/- 7 units
• Qeb 3: 71 - 100 +/- 10 units
  (kev tso cai hloov pauv los ntawm tus nqi nominal teev los ntawm tus neeg xa khoom txheej)

3. Txheej thickness

EN ISO 2360
Lub thickness ntawm cov txheej rau txhua qhov yuav tsum tau ntsuas ntawm qhov tseem ceeb ntawm qhov chaw tsis pub tsawg tshaj tsib qhov ntsuas (appr.1 cm2) nrog 3 txog 5 qhov sib cais nyeem ntawm txhua qhov chaw. Qhov nruab nrab ntawm qhov kev nyeem ntawv cais ntawm ib cheeb tsam ntsuas muab qhov ntsuas tus nqi kom raug kaw rau hauv daim ntawv tshuaj ntsuam xyuas. Tsis muaj qhov ntsuas qhov ntsuas yuav tsawg dua 80% ntawm tus nqi qis kawg nkaus, txwv tsis pub qhov ntsuas tuab tag nrho yuav suav tias yog qhov tsis txaus ntseeg.

Qualicoat-Test Methods and Requirements

Hmoov:

• Chav Kawm 11: 60 m
• Chav Kawm 2: 60 m
• Chav Kawm 3: 50 m
• Ob-coat hmoov system (chav kawm 1 thiab 2): 110 μm
• Ob-coat PVDF hmoov system: 80 μm

Ua kua txheej

• Ob lub ntsiab xim: 50 μm
• Electrophoretic txheej: 25 μm

Lwm cov txheej txheem txheej txheej yuav xav tau cov txheej txheej sib txawv, tab sis lawv tsuas yog siv tau nrog kev pom zoo los ntawm Pawg Thawj Coj.

Qualicoat-Test Methods and Requirements

Cov txiaj ntsig yuav tsum raug ntsuas raws li pom los ntawm plaub qhov piv txwv (tsawg kawg txheej tuab rau txheej txheej ntawm 60 μm):
Piv txwv 1:
Ntsuas qhov ntsuas hauv μm: 82, 68, 75, 93, 86 nruab nrab: 81
Rating: Cov qauv no zoo kawg nkaus txaus siab.
Piv txwv 2:
Ntsuas qhov ntsuas hauv μm: 75, 68, 63, 66, 56 nruab nrab: 66
Kev Ntsuas: Cov qauv no yog qhov zoo vim tias qhov nruab nrab txheej tuab yog ntau tshaj 60 μm thiab vim tias tsis muaj nqi ntsuas tsawg dua 48 μm (80% ntawm 60 μm).
Piv txwv 3:
Ntsuas qhov ntsuas hauv μm: 57, 60, 59, 62, 53 nruab nrab: 58
Kev Ntsuam Xyuas: Cov qauv no tsis txaus siab thiab los ntawm nqe lus "cov qauv tsis lees paub" hauv cov lus 5.1.4.
Piv txwv 4:
Ntsuas qhov ntsuas hauv μm: 85, 67, 71, 64, 44 nruab nrab: 66
Rating:
Cov qauv no tsis txaus siab txawm hais tias qhov nruab nrab txheej txheej yog ntau tshaj 60 μm. Kev tshuaj xyuas yuav tsum raug xam tias ua tsis tiav vim qhov ntsuas tus nqi ntawm 44 μm yog qis dua qhov kev zam ntawm 80% (48 μm).

4. Adhesion

EN ISO 2409
Daim kab xev nplaum yuav tsum ua raws li tus qauv. Qhov sib nrug ntawm qhov kev txiav yuav tsum yog 1 hli rau cov txheej tuab txog li 60 μm, 2 hli rau cov tuab ntawm 60 μm thiab 120 μm, thiab 3 hli rau cov txheej tuab.
TSEEM CEEB: Qhov tshwm sim yuav tsum yog 0.

5. Kev nkag mus
EN ISO 2815
YUAV TSUM TAU:
Yam tsawg kawg nkaus 80 nrog rau qhov yuav tsum tau txheej txheej thickness.

6. Cupping xeem
Tag nrho cov hmoov txheej tshwj tsis yog chav kawm 2 thiab 3 hmoov 2: EN ISO 1520
Qib 2 thiab 3 hmoov:
TS EN ISO 1520 Kev kuaj kab xev rub adhesion raws li tau teev tseg hauv qab no:
Siv daim kab xev nplaum (saib ntu 2.4) rau sab coated ntawm lub vaj huam sib luag kuaj tom qab lub tshuab deformation. Npog qhov chaw los ntawm nias kom ruaj khov tiv thaiv cov txheej txheem kom tshem tawm cov voids lossis cov hnab ntim cua. Rub daim kab xev tawm ntawm lub kaum sab xis mus rau lub dav hlau ntawm lub vaj huam sib luag tom qab 1 feeb.

YUAV TSUM TAU:

•  - Yam tsawg kawg 5 mm rau hmoov txheej (chav kawm 1, 2 thiab 3)
• - Yam tsawg kawg 5 hli rau cov kua coatings tshwj tsis yog - ob lub ntsiab xim thiab lacquers: yam tsawg kawg 3 hli - dej-thinnable xim thiab lacquers: yam tsawg kawg 3 hli
• - Yam tsawg kawg 5 hli rau electrophoretic txheej

Yuav kom qhia tau tias, qhov kev ntsuam xyuas yuav tsum tau ua ntawm ib txheej nrog ib lub thickness approximating yam tsawg kawg nkaus yuav tsum tau.
Saib ntawm qhov muag liab qab, cov txheej yuav tsum tsis txhob muaj qhov cim ntawm kev tawg lossis tawg, tshwj tsis yog rau chav kawm 2 thiab 3 hmoov.

Qib 2 thiab 3 hmoov:
Saib nrog lub qhov muag liab qab, lub txheej yuav tsum tsis txhob pom ib qho kev qhia ntawm detachment tom qab daim kab xev rub adhesion test
