Abstract

The utility model discloses a visual high-temperature foam performance testing device which comprises a gas transmission system, a constant-temperature circulating system, a shooting system and a foam performance evaluation system, and the gas transmission system is connected with the foam performance evaluation system through a bottom valve of a double-layer chromatographic column at the bottom; and the constant-temperature circulating system is connected with the foam performance evaluation system through a connector on the left lower side and a connector on the right upper side of the double-layer chromatographic column. The visual high-temperature foam performance testing device is connected with a constant-temperature circulating system to analyze the performance of high-temperature foam. The constant-temperature circulating system is composed of a constant-temperature water bath box, a water pump and a high-temperature-resistant silicone tube, and uniform heating of the double-layer chromatographic column is achieved through jacket water circulation. High-purity distilled water is used in the water bath box, heat stability is guaranteed, the total cost of components is far lower than the price of a high-temperature foam analyzer adopting an airflow method in the market, and low-cost and efficient temperature control is achieved.
