Overview of Vika softening point test machine and experimental steps principle

The Vica softening point test machine can be used to determine the thermal deformation temperature and Vica softening point temperature of various thermoplastic materials such as plastics and rubbers. Widely used in the production, scientific research and teaching of plastic raw materials and products. What I want to share with you this time is the overview of the Vika softening point test machine and the experimental steps and principles. Let’s learn about it together.

1. Overview of Vika softening point test machine

The VICA softening point test machine uses computer control technology and WINDOWS Chinese (English) interface to automatically measure and control temperature and deformation, draw test curves in real time, automatically calculate test results, store historical data, and print out test reports. This phone is currently an advanced domestic model and is very popular among new and old users. The instrument meets the requirements of: GB1633, GB1634 and other standards.

The Vika softening point test machine uses computer control to display temperature, deformation and other data in real time, draw curves, and indicate the current test status of each channel. It can compare three channels of data, enlarge, reduce the curve, and observe locally. After setting the plan, the test can be automatically completed and a test report will be given. The LCD screen display can display the test temperature, set the upper limit temperature, and automatically record the test temperature. The heating can be automatically stopped after the temperature reaches the upper limit.

The Vica softening point test machine is equipped with a sample protection device to prevent the sample from tilting or displacing during the test and causing the test failure. The box is closed during temperature calibration to avoid the generation of smoke from the room when the temperature is high. It is equipped with a special calibration thermometer insertion device for easy and accurate calibration. Direct-read displacement correction, short correction time, accurate and convenient. Thermal deformation centering device ensures accurate stake. Automatically calculate the test parameters and add weight weight.

2. Principles of experimental steps of VICA softening point test machine

Test steps for Vica softening point testing machine, install a needle or a pressing head. Turn on the power supply, press the power button, and the power indicator light is on. Place the sample and perform load calculation and loading. Set the temperature increase rate and temperature upper limit. After the dial is zeroed, turn on the mixing motor to heat the medium evenly, and then start the test. When you need to restart or reset the parameters, press the "Reset" key. During the experiment, data are recorded when the sample reaches the specified deformation amount. Remove the sample immediately after the test to prevent the sample from melting or falling into the medium box. Query the test data and calculate its average value. Temperature accuracy: ±0.5℃. Temperature resolution: 0.1℃. Deformation range: 0-1mm. Deformation accuracy: 0.01mm. Electric displacement zeroing. Automatic collection of experimental data. Built-in printer. Load range: 0.75N-50N. Test span: 60-120mm continuously adjustable.

The experimental principle of Vika softening point test machine, the heat resistance of a polymer usually refers to its ability to maintain its physical and mechanical properties when the temperature rises. The heat-resistant temperature of a polymer material refers to the temperature when it reaches a certain deforming value under a certain load. The temperature at which deformation occurs is usually called the softening point TS of the plastic. Because different test methods use each have their own specified parameters, the physical significance of the softening point is not as clear as the glass transition temperature. Commonly used Vika heat resistance, Martin heat resistance and thermal deformation temperature testing methods to test the heat resistance of plastics. The test results of different methods have no quantitative relationship with each other, and they can be used to compare different plastics relatively.
