The putty flexibility tester is a testing instrument used in the paint coating industry to judge the cracks and peeling of the putty film after the putty film is bent. The putty flexibility tester is designed and manufactured according to the GB1748-88 standard.
QTB膩?zhàn)尤犴g性測(cè)定儀工作原理簡(jiǎn)介：
該儀器主要由壓架與脫模兩個(gè)部分組成，使用時(shí)**先將壓緊輥柄和壓架放置托模的后端，使托膜顯露出來(lái)，然后將樣板插入托膜后端的小槽內(nèi)并用壓緊柄使偏心軸壓住樣板的一端，然后將壓架搬下通過(guò)壓架上的滾動(dòng)軸使樣板沿著托膜表面均勻地彎曲變形，壓架搬至定位肖處為上后觀察樣板膩?zhàn)幽け砻娴奈锢碜兓?/span>

Brief introduction to the working principle of QTB putty flexibility tester:
The instrument is mainly composed of two parts: the holder and the demoulding. When using it, first place the compaction roller handle and the holder on the rear end of the supporting mold to fully expose the supporting film, and then insert the sample plate into the small end of the supporting film. In the groove, the eccentric shaft is pressed against one end of the sample plate with a compression handle, and then the holder is moved down through the rolling shaft on the holder to make the sample bend and deform uniformly along the surface of the supporting film. Observe the physical changes on the surface of the sample putty membrane.
There are two specifications of Tora: R25 R50
Evaluate the flexibility of a paint film by its ability to deform with its substrate without damage under specified conditions
The test technology is specific: Under the conditions specified in the standard, after bending the test plate, the diameter of the curved film when the putty film cracks and falls is expressed in mm)
