Embodiment 1

[0062] See image 3 , Figure 3-1 and Figure 4 .

[0063] A heating chamber 1 with a cover 22 with an observation window (the bottom of the heating chamber is a sandwich wall, electric heating elements of equal power density are installed in the interlayer, and filled with light rock wool in the interlayer) made of stainless steel plate The heating chamber 1 and the two rectangular linear guide rails 6 made of aluminum alloy with the linear displacement digital display ruler 14 are fixed on a base 20 made of aluminum alloy plate, and the linear guide rails 6 are located under the heating chamber 1 ; On the linear guide rail 6 below the heating chamber 1, there are two base plates made of stainless steel plates of the constant velocity bidirectional stretching mechanism, and one passes through the bottom of the constant velocity bidirectional stretching mechanism 2 two bottom plates and is made of stainless steel rods One end of the two-way screw 16 is placed in the two-way...

Embodiment 2

[0073]Using the micro-extensometer of Example 1, put it into the sample cell of a common infrared spectrometer such as TENSOR 27 or EQUINOX 55 produced by BRUKER Company in the United States, and obtain the infrared spectrum of the sample simultaneously at room temperature to 280 ° C and in a stretched state.

[0074] Syndiotactic polypropylene (sPP) film, the size length × width × thickness is 10 × 3 × 0.1mm, stretched at 60°C, the tensile speed is 10mm / min, and the tensile strain is 100%, 150%, 200%, 250%, 300% and 400%, the infrared spectrum is as Figure 6 shown.

Abstract

The present invention relates to a mini-type extensograph on infrared spectrometer to process infrared red spectroscopic analysis of fibre material and film material in different temperature and different tensional state. Heating chamber in which has high temperature resistance linear guide and sample clamp, linear guide with linear displacement digital ruler are mounted on the base, and a constant velocity bidirectional tension mechanism with push pull rod connected with sample clamp seat and through the heating chamber, and bidirectional screw through the bottom of constant velocity bidirectional tension mechanism and inosculated with snail button of fixation block fixed on the bottom of two soleplates of constant velocity bidirectional tension mechanism are mounted on the linear guide. The bidirectional screw is connected with rapid motion mechanism and shaft sleeve of reducer to realize tension the sample in the conditions of heating, heat preservation-constant temperature under the control of temperature controller, linear sport speed control-display device, linear displacement control display device and stress sensor display device.

Description

technical field [0001] The invention relates to temperature-changing dynamic infrared spectrum testing equipment for polymer material samples, in particular to a miniature stretcher on an infrared spectrometer used for infrared spectrum testing of fiber materials and film materials at different temperatures and stretching states. Background technique [0002] Existing various infrared spectroscopic testing equipments test the structural changes of samples at room temperature or variable temperature (below room temperature or above room temperature). However, the existing mechanical testing equipment for various samples (such as the tensile instrument produced by INSTRON Company of the United States) can only provide the mechanical properties of the sample (such as modulus, elongation at break and stress-strain curve), etc., but cannot simultaneously test the sample. Structural change analysis, i.e. the change in mechanical properties and the change in structure of the sample...
