Problems solved by technology
The conventional combined polyether polyol experimental system consumes a lot of materials, and the polyurethane foam produced is difficult to handle directly. Therefore, on the basis of maintaining system stability, the number of single sample preparations is reduced and the efficiency of sample preparation is improved. The formulation of combined polyether polyols R&D is extremely important

Abstract
The invention discloses a high-throughput sample preparation device, which includes a liquid supply part, a metering part and a sample preparation part. There are at least two liquid supply parts. A metering module, each equivalent metering module is connected to the sample preparation part through the metering part; the metering part includes a difference metering module and a plurality of liquid inlet pipes arranged in parallel at the liquid inlet end of the difference metering module, Each of the liquid inlet pipes has a liquid inlet branch pipe connected to each of the equal metering modules; the difference metering module is internally provided with a volume metering unit that communicates with the liquid inlet pipes one by one, and each The outlet ends of the volume metering units are all in communication with one of the sample preparation parts. The invention is used in the research and development of combined polyether polyols, and the high-throughput sample preparation device of the invention can improve the formula screening efficiency of combined polyether polyols and reduce the material consumption and waste output of test work.
Description
technical field [0001] The invention relates to the technical field of compound preparation and research, in particular to a high-throughput sample preparation device for compound polyether preparation. Background technique [0002] Combined polyether polyol is a kind of polyurethane raw material, commonly known as "white material" in the industry. After it is mixed with polyisocyanate (commonly known as "black material") and molded, it can form a polyurethane polymer material with specific properties. Due to the high activity of polyisocyanate molecules, it is difficult to modify and adjust them. The final structural performance of polyurethane products is highly dependent on the formulation adjustment of combined polyether polyols. The conventional combined polyether polyol experimental system consumes a lot of materials, and the polyurethane foam produced is difficult to handle directly. Therefore, on the basis of maintaining system stability, the number of single sample...
