The putty flexibility tester is a special equipment that complies with the GB/T 1748 standard and is mainly used in the paint coating industry. This instrument is used to evaluate the flexibility properties of paint putty to determine its suitability and durability.
The Principle of the putty flexibility tester is to apply force to the putty sample under certain conditions and observe its deformation under the force. The instrument provides certain load and deformation conditions, which can simulate the stress and deformation conditions in the actual use environment. The flexibility and durability of the putty are evaluated by applying force to the putty sample and observing whether it cracks, falls off or deforms.
Widely used in the paint coating industry to judge the cracks and shedding of the putty film after the film is bent. The instrument has a reasonable structure and is convenient and reliable to use.
The instrument is mainly composed of two parts, the pressing frame and the demoulding. When using, first place the pressing roller handle and the pressing frame at the back end of the supporting film, so that the supporting film is completely exposed, and then insert the sample into the small groove at the rear end of the supporting film. And use the pressing handle to make the eccentric shaft press one end of the sample, and then move down the press frame and pass the rolling shaft on the press frame to make the sample bend and deform evenly along the surface of the supporting film, move the press frame to the positioning Xiao for the last observation of the sample Physical changes on the surface of the putty film.
