XRW-300C Thermal Deformation and Vicat Softening Point Temperature Measuring Instrument

The products of thermal deformation and Vicat softening point temperature tester are introduced in detail.

It is mainly used for the determination of thermal deformation and Vicat softening point temperature of polymer materials (such as plastics, rubber, nylon, electrical insulating materials, etc.). It is suitable for colleges and universities, scientific research units and product quality supervision and inspection units. This machine adopts Windows 98, Windows 2000 or Windows XP Chinese operation interface and control software. During the test process, it can real-time monitor the curve trend of test temperature and test deformation, and dynamically draw the curve of temperature and deformation in real time, so as to realize the historical storage and print the test report, so as to query the previous test data at any time in the future and carry out various experimental data. The comparative study is a highly intelligent testing instrument. When the mouse clicks on any part of the deformation-temperature curve, the interface will automatically display the deformation and temperature value.

The temperature tester for thermal deformation and Vicat softening point is a vertical cabinet structure. 45o double helix automatic stirring system is used in the constant temperature medium box. The oil tank has a special structure, good temperature uniformity, and high accuracy (+0.1 C). It adopts advanced thyristor to control temperature, displacement sensor has fine-tuning and fine-tuning double-tuning mode, has emergency stop switch, and the rear control panel is door-type structure with locks. It is convenient for machine maintenance and maintenance, and the lifting system is integrated into one model to reduce noise. Therefore, the temperature gradient of the medium is small and the constant temperature is uniform. When the test temperature reaches the upper set temperature, the heating stops automatically. The test stand has the function of automatic lifting and lowering. It is easy to operate and has excellent performance-price ratio in the same type of machine.

Vika (VST) tester: Put the sample in liquid medium or heating box, and measure the temperature of standard pressure needle under the action of (50 + 1) N force under the condition of constant temperature rise, when it is pressed into the sample cut from the pipe or fittings for 1 mm.

Standard specimens are subjected to constant load of three-point bending in a flat (preferred) or side-cubic manner, which results in one of the bending stresses specified in the relevant parts of GB/T 1634. Under uniform heating conditions, the temperature at which the standard deflection corresponding to the specified bending strain increment is measured.

Side-up: There are two kinds of "flat" and "side-up", and it is clearly pointed out that the side-cube is only an alternative and will be cancelled.

Span: The distance between the two contact lines of the bearing and the specimen is changed from one (100 mm) to two (64 mm) and 100 mm (lateral). The tolerance requirement is that the span L should be (100 + 1) mm and the span L should be (64 + 1) mm.
