百格刀根据ISO2409-1974标准设计制造的。主要适用于有机涂料附着力的测定。不仅适用于实验室,也可用于各种条件下的施工现场。

The paint film cross-cutting device is designed and manufactured according to the ISO2409-1974 standard. It is mainly suitable for the determination of the adhesion of organic coatings. Not only for laboratories, but also for construction sites under various conditions.

 

百格刀工作原理和适用范围:

该仪器以一定规格的工具将涂层做格阵图形切割并穿透,规格完成的图形按六级分类,评定涂层从底材分离的抗性。

本划格器有三种规格间距的多刃切割刀(1mm、2mm、3mm)按不同实验条件可供选择。1mm间距的多刃切割刀适用于涂膜厚度<60um的试片,2mm间距的多刃切割刀适用于涂膜厚度<60~120um的试片,3mm间距的多刃切割刀是为特殊用途而设计的。

The working principle and scope of the film cross-cutting device:
The instrument cuts and penetrates the coating pattern by a tool of a certain specification, and the finished pattern is classified into six levels to evaluate the resistance of the coating from the substrate separation.
This cross-cutting machine has three-size multi-blade cutting knives (1mm, 2mm, 3mm) which can be selected according to different experimental conditions. The multi-blade cutter with 1mm pitch is suitable for test strips with a coating thickness of <60um. The multi-blade cutter with 2mm spacing is suitable for test strips with a coating thickness of <60~120um. The multi-blade cutting cutter with 3mm spacing is for special purposes. Designed.

 

百格刀特点:

用于均匀划出一定规格尺寸的方格,通过评定方格内涂膜的完整程度来评定涂膜对基材附着程度,以‘级’表示。它主要用于有机涂料划格法附着力的测定,不仅适用于实验室,也可用于各种条件下的施工现场。(这种刀片及加工工艺,只适用于非金属和软金属基材上面的涂层的附着力测试,需要均衡用力使每条划痕都划穿涂层)。

Paint film cross-cutting features:
It is used to uniformly draw a square of a certain size, and the degree of adhesion of the coating film to the substrate is evaluated by evaluating the integrity of the coating film in the square, which is represented by 'level'. It is mainly used for the determination of the adhesion of organic paint cross-cutting method, not only for the laboratory, but also for the construction site under various conditions. (This blade and process is only suitable for adhesion testing of coatings on non-metallic and soft metal substrates, requiring a balanced force to allow each scratch to pass through the coating).

百格刀使用方法:

试片必须按ISOR1514及ISO2808的规定制备:

将试片放置在有足够硬度的平板上:

根据需要实验的涂膜厚度,选用规格合适的多刃切割刀,将图中件2

松开一圈,搬动刀体3或螺纹轴1,即可改换多刃切割刀,然后锁紧件2即能使用:

手持划格器手柄,使多刃切割刀垂直于试片平面:

以均匀的压力,平稳地不颤动的手法和20~~50mm/s的切割速度割划;

将试片旋转90度角,在所割划的切口上重复以上操作,以使形成格阵图形;

用软毛刷沿格阵图形的,两对角线轻轻地向后5次向前5次的刷试片;

试验至少在试片的三个不同位置上完成,如果三个位置的实验结果不同,应在多于三个位置上重复试验,同时记录全部结果。

Paint film cross-cutting method:
★ Test strips must be prepared in accordance with ISOR1514 and ISO2808:
★ Place the test piece on a plate with sufficient hardness:
★ According to the thickness of the film to be tested, select the multi-blade cutting knife with the appropriate specifications.
After loosening one turn and moving the cutter body 3 or the threaded shaft 1, the multi-blade cutter can be changed, and then the lock member 2 can be used:
★ Handle the cross-cutting handle so that the multi-blade cutter is perpendicular to the test plane:
★ With uniform pressure, smooth non-fibrillation and cutting speed of 20~~50mm/s;
★ Rotate the test piece at a 90-degree angle and repeat the above operation on the cut slit to form a lattice pattern;
★ Using a soft brush along the pattern of the grid, the two diagonal lines are gently turned back five times and the brush is tested five times;
★ The test is done at least at three different locations on the test piece. If the experimental results at the three locations are different, the test should be repeated at more than three locations and all results recorded.

★Single side: 1mm 100 grid, 2mm 100 grid (wooden handle), 1 blade

 

百格刀注意事项

所有切口应穿透涂层,但切入底材不得太深;

如因涂层过厚和过硬而不能穿透到底材,则该试验无效,应在试验报告中说明;

在特殊情况下或有特殊要求时必须配合胶带测定。胶带一般是25 mm宽的半透明胶带,背材为聚脂薄膜或醋酸纤维。将胶带贴在整个划格器上,然后以A小角度撕下,结果可用漆膜表面与脱落面积的比例来求得:

实验应在温度23±2°C和相对湿度50±5%中进行

QFH paint film cross-cutting notes:
★ All cuts should penetrate the coating, but the cut into the substrate should not be too deep;
★ If the coating is too thick and too hard to penetrate the substrate, the test is invalid and should be stated in the test report;
★ It must be measured with tape in special cases or when there are special requirements. The tape is typically a 25 mm wide translucent tape with a polyester film or acetate. Apply the tape to the entire cross-hatch and then tear it off at a small angle. The result can be obtained by the ratio of the surface of the paint film to the area of the peeled off:
★ The experiment should be carried out at a temperature of 23 ± 2 ° C and a relative humidity of 50 ± 5%.
