Embodiment Construction

[0012] The specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific embodiments.

[0013] Unless expressly stated otherwise, throughout the specification and claims, the term "comprise" or variations thereof such as "includes" or "includes" and the like will be understood to include the stated elements or constituents, and not Other elements or other components are not excluded.

[0014] In the process of preparing microcapsules by in-situ polymerization, a constant temperature is required. After the prepared emulsion is stable, add prepolymer, and then slowly adjust the pH value to a certain range. Microcapsules are prepared by using the laboratory microcapsule preparation device of the present invention.

[0015] Such as figure 1 As shown, a laboratory microcapsule preparation device according to...

Abstract

The invention discloses a preparation device for a lab microcapsule. The preparation device comprises a stirrer wherein a microcapsule preparation liquid is put in the stirrer; a pH tester which is connected with a sensor of the pH tester, wherein the sensor of the pH tester extends into the microcapsule preparation liquid and detects the pH value of the microcapsule preparation liquid; a supporting rack; and a separating funnel which is arranged on the supporting rack and located above the stirrer, wherein a valve for controlling the fluid flow rate is arranged at the funnel of the separating funnel. The preparation device for the lab microcapsule disclosed by the invention adds a pH value adjusting liquid into the separating funnel during the test. The dropwise adding speed of the pH value adjusting liquid is controlled through a control valve thereon, so that the workload of adjusting the pH value by manually dropwise addition is greatly reduced, and the work of slowly adjusting the pH value becomes smooth, stable and controllable.

Description

technical field [0001] The invention relates to the field of experimental instruments and equipment, in particular to a preparation device for laboratory microcapsules. Background technique [0002] At present, in the process of preparing microcapsules by in-situ polymerization in the laboratory, a certain constant temperature environment is required, and the pH value of the reaction system must be gradually adjusted, especially in the slow adjustment of the pH value. Under the current experimental conditions, it is necessary to use a rubber head The dropper is added drop by drop, and the time is between 30min-90min, which is very inconvenient. [0003] The information disclosed in this Background section is only for enhancing the understanding of the general background of the present invention and should not be taken as an acknowledgment or any form of suggestion that the information constitutes the prior art that is already known to those skilled in the art.
