Problems solved by technology
[0005] At present, muffle furnaces are generally used for pretreatment operations, but the rapid cooling of materials has always been a problem. If they are cooled inside the equipment, the cooling speed is very slow; if the materials are taken out and cooled, they will come into contact with air and cannot Meet the test requirements

The invention discloses high polymer material glass-transition temperature pretreatment equipment, and belongs to the technical field of medical instrument inspection. The equipment structurally comprises a hearth and a shock cooling cavity which are sequentially arranged. The hearth and the shock cooling cavity are separated through a heat insulation block, and a valve for driving the heat insulation block to be opened and closed is arranged on the heat insulation block. A test piece frame is arranged in the equipment body. One end of the test piece frame is used for installing a test piece,and the other end is connected with a driving device. The driving device drives the test piece frame to move between the hearth and the shock cooling cavity, and the hearth and the shock cooling cavity are provided with an air inlet and an air outlet respectively. According to the technical scheme, the material can be rapidly cooled under the condition that the material does not make contact withair after being heated, the equipment is suitable for high polymer material glass-transition temperature pretreatment and alloy material heat elimination history pretreatment, use is convenient, efficiency is high, and the requirements of related standards are met.
Description
technical field [0001] The invention relates to the technical field of medical device inspection, in particular to pretreatment equipment for medical device inspection, in particular to a glass transition temperature pretreatment device for polymer materials. Background technique [0002] Glass transition is a reversible change of an amorphous polymer or an amorphous region in a semicrystalline polymer from a viscous fluid or rubbery state to a hard, relatively brittle glassy state. The glass transition temperature refers to the temperature at the approximate midpoint of the temperature range in which the glass transition occurs. [0003] The glass transition temperature directly affects the performance and process performance of the material. In order to ensure the safety and reliability of the medical device, the material of the medical device must be measured by the glass transition temperature. Before the glass transition temperature is measured, Material pretreatment i...
