Bending Test – Qualicoat Test Process

Tag nrho cov txheej txheem organic tshwj tsis yog chav kawm 2 thiab 3 hmoov txheejDaim ntawv pov thawj: EN ISO 1519
Qib 2 thiab 3 hmoov txheej:
TS EN ISO 1519 Kev kuaj kab xev rub adhesion raws li tau teev tseg hauv qab no:
Siv daim kab xev nplaum rau qhov tseem ceeb 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.
Kev ntsuam xyuas yuav tsum tau ua ntawm cov txheej txheem organic nrog lub thickness kwv yees li qhov tsawg kawg nkaus.
Nyob rau hauv cov ntaub ntawv ntawm ib tug tsis zoo tshwm sim, khoov xeem yuav tsum tau rov qab rau ntawm ib tug vaj huam sib luag coated nrog ib tug tuab ntawm

• Chav Kawm 1 thiab 2: 60 txog 70 μm
• Chav Kawm 3: 50 txog 60 μm

YUAV TSUM TAU:
Khoov ib ncig ntawm 5 mm mandrel rau tag nrho cov organic coatings tshwj tsis yog rau ob-tivthaiv thiab dej-thinnable kua txheej. Rau cov no, siv 8 mm mandrel.
Siv lub zeem muag kho ib txwm, cov txheej yuav tsum tsis txhob pom muaj kev tawg lossis tawg, tshwj tsis yog rau chav kawm 2 thiab 3 hmoov txheej.
Class 2 thiab 3 hmoov txheej:
Siv lub zeem muag kho ib txwm muaj, cov txheej txheem organic yuav tsum tsis pom muaj kev cuam tshuam tom qab daim kab xev rub adhesion.
