Super-high temperature Vicat and thermal deformation testing machine

Abstract

The invention discloses a super-high temperature Vicat and thermal deformation testing machine, and relates to the field of test instruments. The testing machine comprises a heating furnace, a measuring structure, and an elevating structure. The bottom of the heating furnace is provided with a pumping chamber. A heating tube is arranged in the heating furnace. A sample can be placed in the bottomof the measuring structure. The measuring structure stretches into the heating furnace. The temperature is measured by a temperature sensor. The elevating structure controls the measuring structure soas to determine whether the measuring structure stretches into the heating furnace or not. The heating tube is tightly arranged in the furnace, the pumping chamber is arranged in the bottom of the furnace to increase the temperature of the interior of the furnace, the measuring structure is arranged in the furnace, multiple measuring units are arranged on the measuring structure and cooperate with each other, thus the super-high temperature Vicat and thermal deformation tests can be preformed, furthermore, alumina powder is taken as the heat conduction medium, the safety is enhanced, environment is better protected, the furnace is in a cylindrical shape, the whole measuring structure is compact, the heat loss is reduced, the heat is converged, the temperature range is wide, the structureis reasonable, the operation is convenient, and the precision is high.

Description

technical field [0001] The invention relates to the field of testing instruments, in particular to an ultra-high temperature plastic Vicat and thermal deformation testing machine. Background technique [0002] Plastic is a very important material in modern society, but most plastics have poor heat resistance and tend to change their properties at high temperatures. Before using plastics, it is necessary to measure their heat distortion temperature and Vicat softening point. The range is from normal temperature to 300 degrees Celsius, so it is impossible to measure ultra-high temperature plastics. Contents of the invention [0003] The invention provides an ultra-high-temperature plastic Vicat and thermal deformation testing machine, the machine can heat up to 500 degrees Celsius, can measure the Vicat softening point and thermal deformation temperature of ultra-high-temperature plastics, and has a reasonable structure. [0004] In order to achieve the above object, a kind...

Problems solved by technology

[0002] Plastic is a very important material in modern society, but most plastics have poor heat resistance and tend to change their properties at high temperatures. Before using plastics, it is necessary to measure their heat distortion temperature and Vicat softening point. The range is from room temperature to 300 degrees Celsius, so it is impossible to measure ultra-high temperature plastics
