喷漆附着力测试

1.Blade with 6 knifepoint

2. 3M600 adhensive tap

3. Samples(painted parts)

1.十字划刀/百格刀(6片)，2.3M600膠紙，3.待測樣品。

[] procedure程序: [/]

6.1 Take samples from painting line and then put these samples in normal environment more than 1 hour.

將待測件從挂架上取下后，置于空气中至少冷卻1小時以上；


6.2 Moving the cutter in one steady motion(pressing just enough to cut through to the substrate)make a series of parallel cuts,approcimately 20mm long,if part surface is not flat,more than half series cuts can be acceptable.

用十字划刀在待測部件涂層表面划出长约20MM一组平行線.(划线时确保划刀底部贴近样品表面为准),如待測面為曲面，多于半组平行线(3条)亦可，但不可低于3條；


6.2 Make a second series of cuts at right angles to the first,making a lattice pattern.

继续用十字划刀划出相同的一组垂直线使画出的图形成格子形状.


6.3 Gently brush the surface with a soft brush to remove loose flakes of coating.

用軟毛刷輕刷划線表面去掉碎沫；


6.4 Put 3M600 adhensive tap on the surface(attention:there mustn't be air bubbles between tap and painted parts) and then keep adhensive tap on the surface for one or two minutes.

將無气泡之3M膠紙貼于划線上，膠紙与樣品間應無气泡，保留1~2分鐘；


6.5 Pull out half adhensive tap from samples with 60 degree and invariable speed.

以約60度角度恒定速度，將膠紙撕起.


6.6 Judge the result according to following table and then record the result.

根据下表判定測試結果做好测试记录.


6.7 If needed, all surfaces should be tested for one sample.

如有可能，要求除背面以外，其余5面均需測試。


6.8 If customer has any other special requirements about adhension test,please refer to

responsible inspection instruction in which quality engineer highlighted the special

requirements

对于附着力测试,如果客户有其它特殊要求,请参考相应的检验指引中客户的特殊要求.

ISO 描 述
Discription 表面圖示
Surface sketch map

0 划線邊緣完全平整,正方形完整。
the edges of the cuts are completely smooth,none of the squares of the lattice is detached.

1
涂層在線交叉點有破損,破損面積明顯小于正方形總面積的 5% Detachment of flakes of the coating at the intersections of the cuts.a cross cut area not significantly greater than 5% is affected.

2
涂層在線的邊緣和或線交叉點有破損,破損面積明顯大于正方形總面積的5%,但小于正方形總面積的 15%。
The coating has flaked along the edges and/or at hte intersections of the cuts.A cross cut area significantly greater than 5%,but not significantly greater than 15% is affected.

3
涂層在線的邊緣和或部分或全部正方形有大面積脫落,破損面積明顯大于正方形總面積的15%,但小于正方形總面積的35%。
The coating has flaked along the adges of the cuts partly or wholly in large ribbons, and/or it has flaked partly or wholly on different parts of the squares.A cross cut area significantly greater than 15%,but not significangly greater than 35%, is affected.

4
涂層在線的邊緣和或部分(或全部)正方形有大面積脫落,破損面積明顯大于正方形總面積的35%,但小于正方形總面積的65%。
The coating has flaked along the edges of the cuts in large ribbons and/or some squares have detached partly or wholly.A cross cut area significantly greater than 35%,but not significantly greater than 65%, is affected.
5 大於4級的大面積脫落。
Any degree of flaking that connot be classified even by classification 4.

[] Disposal for non-conformance parts异常結果的處理: [/]

7.1 If the test result is following ISO 2,3,4 or 5 classification,issue Defect Report to inform responsible person(measuring supervisor and quality engineer etc.) to find out root cause and take corrective actions at once.

如果測量結果属于2,3,4或者5級，必須馬上知會相关人员(测量主管和品质工程师等)，并立即找到根本原因,采取更正措施.
