Novel sampling apparatus for polymer material test

Abstract

The invention discloses a novel sampling apparatus for polymer material test, which comprises a cylinder. A piston is connected in a sliding manner inside the cylinder. First pull rods are arranged ina penetrating manner on the upper and lower sides of the inside of the piston. A first stop plug is fixedly connected between the left ends of the two first pull rods, and a first groove matched withthe first stop plug is arranged in the left side of the piston. The invention relates to the technical field of polymer materials. According to the novel sampling apparatus for polymer material test,the sliding of the first stop plug, the piston and a second stop plug in the cylinder can be controlled by the first pull rods, second pull rods and a third pull rod respectively, and a semi-finishedmaterial melted in a production box can be extracted for testing according to a certain sequence of operation. Because the first stop plug, the piston and the second stop plug are combined closely, material residue can reduced as much as possible, and the influence of material residue on next extraction can be avoided. Sampling can be carried out without opening the production box. The sampling apparatus is convenient to use, and will not affect the quality of materials in processing.

Description

technical field [0001] The invention relates to the technical field, in particular to a sampling device for a novel polymer material test. Background technique [0002] Polymer materials are materials based on polymer compounds. Polymer materials are materials composed of compounds with relatively high molecular weight, including rubber, plastics, fibers, coatings, adhesives and polymer-based composite materials. Polymers are the form of life. All living organisms can be regarded as a collection of macromolecules. Polymer materials are divided into natural polymer materials and synthetic polymer materials according to their sources. Natural polymers are polymer substances that exist in animals, plants and organisms, and can be divided into natural fibers, natural resins, natural rubber, animal glue, etc. Synthetic polymer materials mainly refer to the three major synthetic materials of plastics, synthetic rubber and synthetic fibers, and also include adhesives, coatings a...
