Hot deformation Vicat softening point temperature testerDetailed introduction:

Designed by our companyHot deformation Vicat softening point temperature testerconform toIS075、IS0306、GB/T8802、GB／T1633、GB／T1634According to international and national standards, it is suitable for measuring the thermal deformation and Vicat softening point temperature of various materials.Hot deformation Vicat softening point temperature testerIt is an instrument specifically used to measure the deformation or softening properties of thermoplastic materials under high temperature. It has two functions: one is to measure the thermal deformation temperature, and the other is to measure the Vicat softening point temperature.

Vicat softening point temperature measurementThe principle is to process the sample into a square shape using the cross-sectional area1A square millimeter needle is pressed onto the surface of the sample, and a certain amount of pressure is applied to the needle. Then, the sample is placed in an oil bath and heated at a fixed rate. When the sample softens due to heat, the needle is inserted into the sample. As the temperature increases, the depth of the needle insertion into the sample reaches1mmAt this point, the temperature is the Vicat softening point temperature of the sample.

Measurement of hot deformation temperaturePrinciple:

It is to process the plastic sample to be tested into a strip sample with a certain width and thickness, place it flat or sideways on the sample holder, and apply a certain pressure to the sample through a specially designed pressure head. Then, place it in an oil bath and heat the oil in the bath at a certain heating rate while measuring the deformation of the sample. The temperature at which the deformation reaches a certain value (usually a few tenths of a millimeter) is the thermal deformation temperature of the sample.

The instrument adopts a desktop structure, with a compact and reasonable mechanical structure and a beautiful appearance; Adopting a large fuel tank structure, the temperature field is more uniform to ensure the accuracy of the test. Equipped with dual mixing motors, the heating oil circulation has no dead corners.

Adopting an independent electrical control box ensures that the electrical components are not affected by the heat from the fuel tank and electromagnetic interference, resulting in more stable operation. The control device adopts32positionARMHigh speed embedded system control, a control program specifically designed for optimizing the constant temperature environment required for thermal deformation Vicat testing,24positionADData collection, accurate measurement, and fast adjustment speed. The operation interface adopts a menu operation mode, which is simple to operate, easy to learn and use.
