Abstract
The utility model relates to a gel forming time determinator which is composed of a universal meter, a seal rubber ring, electrodes, a reaction kettle, a control valve and a supercharging device. The electrodes are inserted into the reaction kettle through a through hole which is formed at the upper end of the reaction kettle. The electrodes are connected with the universal meter through a guide line. A juncture position of the guide line and the reaction kettle is sealed and insulated by the seal rubber ring. The reaction kettle is connected with the supercharging device through a pipeline. The control valve is arranged on the pipeline. Based on the process of gel forming, a space net structure is formed by a gel system, and physicochemical property changes so that resistivity of the system is changed. Changes of specific conductance of a gel solution in the reaction kettle are measured by the universal meter and the electrodes under the conditions of high temperature and high pressure, and therefore gel forming time of various gel systems is conveniently and accurately measured, and repeatability of measurement results is good.
