Problems solved by technology

However, the above method still has some disadvantages
In the separation process, the above methods can generally only separate two materials. If multiple materials are to be separated, multiple separation operations are usually required, and the operation is cumbersome.
Among them, the floating-sinking method needs to configure the solution multiple times, while the cent

Abstract

Disclosed is a high polymer material separation method based on a magnetic-Archimedes principle. The method comprises the steps that (1) a medium solution is determined according to the difference of the densities of mixed high polymer samples; (2) the mixed high polymer samples are washed with a washing agent; (3) the mixed high polymer samples are placed in the medium solution; (4) the medium solution is placed in a magnetic suspension detection device, wherein the magnetic suspension detection device comprises two square magnets with same poles arranged in a face-to-face mode; and (5) the high polymer samples with different densities are layered in the medium solution, the different samples are taken out in a layered mode, and separation is accomplished. Compared with the prior art, the method has the beneficial effects that a brand new high polymer material separation method is provided, operation of the required device is easy, the cost is low, the measurement result is easy to observe, the measurement accuracy is high, and the automation of the method is easy to achieve.

Description

technical field [0001] The invention relates to a polymer material separation method, in particular to a polymer material separation method based on the magnetic-Archimedes principle. Background technique [0002] The separation technology of different substances has a wide range of applications in production and research. In terms of polymer molding, the separation of mixed materials plays an important role in raw material screening and waste recycling. [0003] Existing widely used separation techniques include: float-sink method, centrifugation method and so on. The principle of these methods is to separate different substances based on the difference in density of different materials. The floating-sinking method separates two materials by configuring a solution with a density between two different materials, so that the two materials are in the state of suspension and sinking respectively. The centrifugation method separates different materials by delamination through...
