HV500 산화알루미늄을 사용한 열변형 시험기
Overview
The Instron® CEAST HV500 is the latest instrument design to perform HDT and VICAT tests at high temperatures, up to 500°C, making this instrument ideal for research and quality control applications as it is ensuring the capability to test the new generations of techno-polymers, characterized by their excellent properties at high temperature. Using three independent testing stations and with a new cutting-edge heating system for specimens, the CEAST HV500 is simple to use and eliminates environmental concerns associated with oil based systems, such as vapor emissions and oil disposal.
Features
- New innovative heating medium that uses an Aluminum Oxide micrometer-sized powder, which is "fluidized" by compressed air rather than oil
- The pneumatic system, which automatically lowers all three test stations at the beginning of the test and raise them at the end of the test, eliminates the need for operator manual handling
- Automatic pneumatic system to apply and remove weights on the specimens at the start and end of the test
- Both HDT and Vicat tests can be performed simultaneously
- For additional operator safety, the protective cover remains closed until the bath temperature returns to the threshold temperature
- Available as a stand-alone instrument, controlled by microprocessor and soft-touch keyboard, the instrument can be as well connected to a PC for data handling using the Bluehill HV software, ensuring parameters management and process control

CEAST HDT Vicat Series HV500
The effect of temperature on the mechanical properties of plastic materials has a fundamental role in the design of components, especially in the selection of materials. Unlike metals and ceramics, plastics are extremely sensitive to the slightest changes in temperature. The selection of plastics for applications under different temperatures is a complex task. The material must be able to support a stress under operating conditions without losing its strength and without critical distortion. The effect of temperature on geometrical stability and mechanical properties in general can be studied following different procedures and methods like at constant temperature or with a temperature ramp. From very simple units for QC labs to more advanced and automated systems, the Instron line of CEAST Thermal testers are designed to measure the heat deflection temperature (HDT) and the Vicat softening temperature (VST) according to the related ISO and ASTM international standards.
