Problems solved by technology
The test sample is covered by copper mesh, suspended in the extraction tube, and the suspended line is fixed through the interface between the extraction tube and the condensation tube. Between the extraction tube and the grinding port of the condenser tube, the airtightness of the instrument is affected, resulting in inaccurate test results; 2. There are few experimental samples in one test, and it is not easy to distinguish, and the efficiency is not high; 3. The same batch of experimental samples, The same device is used to test in batches, resulting in certain errors

The invention discloses a device for testing the gel content by adopting a Soxhlet method and an operating method of the device. The device comprises a condensing tube, an extraction tube, a liquid collecting bottle and a water bath kettle, wherein the condensing tube is fixed on a fixing table, the lower end of the condensing tube is connected with the extraction tube, the lower end of the extraction tube is connected with the liquid collecting bottle, and the liquid collecting bottle is fixed on the fixing table and placed in the water bath kettle; a sample hanging frame is arranged in the extraction tube, and the sample hanging frame comprises a supporting seat, a supporting seat rod fixed on the supporting seat and a hanging table fixed at the top end of the supporting seat rod; the hanging table is a flat ring strip and is bent to form a sawtooth shape in the peripheral direction, sawteeth face towards an axial direction, and concave positions of the sawteeth are connected with a copper net through hanging ropes. The device disclosed by the invention adopts the sawtooth sample hanging frame with a simple structure and can be used for placing many kinds or many batches of identified samples once, so that the testing efficiency is improved, the hanging ropes are prevented from being placed between the extraction tube and the condensing tube, the problems that the sealing property is poor, the kinds of testing samples is few or single, the test precision is not high, and the efficiency is low in the prior art are effectively solved, and the operating method is simple and convenient.
Description
technical field [0001] The invention belongs to the field of cross-linked polymer performance testing devices, and relates to a cross-linked polymer gel content testing device and an operation method thereof. Background technique [0002] One method of extracting compounds from solid substances is to soak the solid with a solvent for a long time to leach out the desired substance, that is, the long-term leaching method. This method takes a long time, the amount of solvent used is large, and the efficiency is not high. The Soxhlet extraction method is to use the solvent reflux and siphon principle to continuously extract the solid matter by the pure solvent, which not only saves solvent, but also has high extraction efficiency. Grind the solid material before extraction to increase the contact area between solid and liquid. Then put the solid matter in the filter screen sleeve and put it in the extractor. The lower end of the extractor is connected to the round bottom flask...
