High temperature and high pressure resistant visual reaction experiment apparatus

Abstract

The invention relates to a high temperature and high pressure resistant visual reaction experiment apparatus. The apparatus comprises a quartz glass tube, quartz glass plugs, polytetrafluoroethylene sealing rings, stainless steel clamping plates, stainless steel rods respectively having two threaded ends, nuts and gaskets, a sample rack, and an infrared thermal imager. Screw and nut devices are used to apply pressure to the quartz glass cover plugs, the quartz glass tubes and the polytetrafluoroethylene sealing rings in order to seal the quartz glass tubes; and the above heating device is used to heat the apparatus in order to simulate high temperature and high pressure environment, and the infrared thermal imager is used to monitor the reaction process in real time. The positions of the threaded stainless steel rods on the stainless steel clamping plates in the apparatus can be adjusted, so the apparatus can be equipped with the quartz glass tubes with different diameters, wall thicknesses and lengths to meet different experiment requirements; a sample can suspend on the sample rack or is clamped by a clamp as required; and the apparatus has the advantages of low cost, and simple manufacturing and operation. The apparatus is suitable for researching corrosion and immersion of metal materials with various dimensions in a non-strong alkaline solution at a high temperature under a high pressure, and relevant experiments.

Description

technical field [0001] The invention relates to a multifunctional experimental device for corrosion immersion of metal materials in a non-strong alkaline solution under high temperature and high pressure and related experiments. Background technique [0002] In the process of evaluating the corrosion resistance of materials, it is often necessary to immerse the material in a medium at a higher temperature, and then evaluate its performance by observing its corrosion reaction process and measuring various performance parameters of the material. Larger pressure requires containers or equipment that can withstand high temperature and high pressure. Although high-temperature and high-pressure autoclaves can withstand high temperature and high pressure, their inner walls are generally stainless steel. If the material to be tested is a heterogeneous metal, a battery effect will often occur in the corrosive medium and the reaction mechanism will be changed; some experiments require...
