COMPANY PRODUCT

1. Simple Introduction  
It is mainly used for the determination of heat distortion temperature and Vicat softening point temperature of non-metallic materials such as plastic, hard rubber, nylon, electrical insulating materials, long fiber reinforced composite materials, high strength thermosetting laminates. It is easy to operate and precise in control. It is a highly intelligent test instrument widely used in colleges and universities, research institutes and product quality supervision and inspection units.
The machine adopts Chinese operation interface, real-time monitoring test temperature, real-time drawing of temperature and deformation curve, printing test report, realizing historical save, mouse click deformation and temperature curve, the interface will automatically display the deformation amount at that place. And temperature values. The high-precision displacement sensor (Intelligent Remote Dial Indicator) is used to measure the deformation.

3. Working principle
Determination of the Vicat softening point temperature of thermoplastics:
When the temperature is raised at a constant rate, the temperature at which the standard needle is pierced 1 mm deep on the surface of the thermoplastic sample under a certain load condition is measured.
Determination of the heat distortion temperature of plastic bending load: the plastic sample is immersed in a suitable liquid heat transfer medium with constant temperature rise, and the temperature at which the specimen bends and deforms to a specified value under the static bending load of the simply supported beam type .
 
4. Instrument characteristics
Ultra-high intelligent design
After inputting the parameters and placing the sample, the test is started, the dial gauge is automatically cleared, the instrument automatically balances the temperature, and the temperature starts automatically. After the last sample is measured, the experiment is automatically stopped and the data is automatically recorded.
Efficient test efficiency
The hot deformation test can also be done at the same time in a fuel tank. The Vicat test can also be performed. Each test station can be combined into a group to carry out the test. Once the temperature rises, several test reports can be independently produced, which greatly improves the test efficiency.
High precision measurement and control system
The high-performance temperature sensor and the advanced capacitive-gate digital dial indicator are used to accurately measure the small changes of the sample with an accuracy of 5μm. The advanced PID algorithm and the all-optical isolation phase-modulation module are used for temperature control to ensure the heating rate error. Less than 0.5 ° C.
Sample rack automatic lifting
The sample holder has an electric lifting function, which can be stopped at any position, and the metal button is beautiful and practical.
Quadruple security
Multiple hardware and software safety design such as mechanical temperature upper limit protection switch, software temperature upper limit protection, test completion automatic stop and administrator operation key to ensure safe and stable operation of the test.
