Description

Technical Field

[0001] The invention relates to the technical field of polymer material synthesis, and in particular to a demoulding and material taking method and a demoulding and material taking device after polymer material synthesis. Background Art

[0002] When synthesizing polymer materials, especially when synthesizing a small amount of polymer materials in the laboratory, it is often difficult to quickly and conveniently take out the thermoplastic elastomer material at the bottom of the synthesis container after the synthesis reaction is completed and cooled. For the commonly used glass reaction tanks or small-diameter cylindrical reactors made of polytetrafluoroethylene, it is difficult to take out the material after preparing the synthetic reactants. The following methods are generally used:

[0003] 1. After breaking the bottom of the glass jar or polytetrafluoroethylene reactor, the polymer synthetic material in the vessel is taken out. However, this method is difficult to operate. The safety risk of breaking the glassware is high, the operation is difficult, and it is easy to produce impurities such as broken slag. The bottom of the polytetrafluoroethylene material is generally difficult to break easily, and the bottom of the cylindrical reactor needs to be cut, which is difficult to operate and easy to contaminate the synthesized material.

[0004] Second, add a good solvent that can dissolve the polymer synthetic material into a glass jar or a polytetrafluoroethylene reactor. After the polymer synthetic material is partially dissolved, pour the solution containing the polymer synthetic material from the vessel into other containers, and then repeatedly add the good solvent to continue to dissolve the remaining synthetic material until it is completely taken out. Then, add the solution into a poor solvent for the polymer synthetic material to precipitate the synthesized polymer material, and finally dry it. This method requires a long time to dissolve the polymer synthetic material and the subsequent precipitation process in the poor solvent, and the added organic solvent may affect the purity of the obtained polymer synthetic material, especially some medical materials need to be non-biotoxic, and the addition of organic solvents will cause them to pollute. Summary of the invention

[0010] S4. The screw and the polymer synthetic material fixed on the screw head can be slowly taken out from the synthesis container by matching the handle on the rear end of the material taking tool with the thread of the screw structure of the material taking tool;

[0011] S5. By rotating the screw in the opposite direction, the taken-out polymer synthetic material can be separated from the main body of the material taking tool, thus completing the demoulding and material taking operation.

[0013] The synthesis container is a glass vessel or a polytetrafluoroethylene synthesis tank commonly used in experiments.

[0014] The polymer synthetic material is an integral solid polymer synthetic material at room temperature.

[0016] In step S4, the handle is placed against the mouth of the synthesis container, and the screw and the polymer synthesis material fixed to the screw head are lifted from the synthesis container together by rotating the handle until they are finally separated from the synthesis container.

[0018] It also includes a locking piece, which includes a horizontal hole and a vertical hole. The horizontal hole and the vertical hole intersect to form a cross-shaped channel structure. A vertical through hole is also provided in the middle of the support rod. The support rod is horizontally inserted into the horizontal hole of the locking piece, and the locking piece can rotate longitudinally around the support rod through the horizontal hole.

[0019] The lower opening of the vertical hole of the locking member is an elliptical opening, and the locking member includes a locking position in which only the lower opening of the vertical hole is aligned with the through hole of the support rod by rotating downward around the support rod.

[0020] The locking member also includes a movable position where the lower opening and the upper opening of the vertical hole are aligned with the through hole of the support rod by rotating around the support rod, and the screw structure of the main body passes through the aligned through hole and the vertical hole.
