Abstract

The invention discloses a fiber stretching heating stage and a small angle laser scattering instrument using the fiber stretching heating stage. The fiber stretching heating stage comprises a body anda mechanical stretching device arranged on the body, wherein the mechanical stretching device comprises a fixing unit and an adjusting unit; high polymer fiber material samples are fixed on a first fixing end and a second fixing end of the mechanical stretching device, the first fixing end and / or the second fixing end can move relative to each other along a connecting line, and the high polymer fiber material samples are stretched along with relative movement of the first fixing end and / or the second fixing end; and the adjusting unit is arranged at the first fixing end and / or the second fixing end and drives the first fixing end and / or the second fixing end to move. The small angle laser scattering instrument comprises the fiber stretching heating stage, laser equipment, a polarizing device, a camera shooting device and analytical equipment. According to the fiber stretching heating stage and the small angle laser scattering instrument disclosed by the invention, corresponding changes of a spherulitic growth process and corresponding change data and maps of small angle laser scattering patterns can be observed, analyzed and collected when the length of a to-be-detected sample isstretched to be 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 ...
