Abstract

The invention discloses a fiber drawing heat table and a small-angle laser scattering instrument using the same. The fiber stretching heat table includes a body and a mechanical stretching device arranged on the body; the mechanical stretching device includes a fixing unit and an adjusting unit, and the high polymer fiber material sample is fixed on the first fixed end and the second fixed end of the mechanical stretching device. end, and the first fixed end and/or the second fixed end can move relatively along its line, and the polymer fiber material sample is stretched with the relative movement of the first fixed end and/or the second fixed end; the adjustment unit The adjusting unit is arranged on the first fixed end and/or the second fixed end, and drives the first fixed end and/or the second fixed end to move. The small-angle laser scattering instrument includes a fiber drawing heat station, a laser device, a polarization device, a camera device, and an analysis device. The invention can observe, analyze and collect the corresponding change of the spherulite growth process and the corresponding change data and spectrum of the small-angle laser scattering pattern when the length of the sample to be tested is stretched and changed.

Description

technical field [0001] The invention relates to the field of polymer measuring instruments, in particular to a fiber stretching heat table and a small-angle laser scattering instrument using the same. Background technique [0002] The small angle laser scattering method (Small Angle Laser Scattering, referred to as SALS), is a scientific test method that irradiates a crystalline polymer sample with a laser, and studies the spherulite structure through the heat dissipation pattern generated by the spherulite. It can measure the size, growth rate and deformation of spherulites in polymers, observe the changes of laser scattering patterns during the growth of spherulites, and determine the influence of crystallization temperature on the crystallization process and spherulite size. It makes up for the shortcomings of methods such as electron microscope, X-small angle diffraction and optical microscope, so it has been paid more and more attention to and applied in the aspects of ...
