Coking riser heat exchange equipment heat conduction mud and preparation method thereof
The invention belongs to the technical field of refractory materials, and relates to heat-conducting mud for coking riser heat exchange equipment and a preparation method of the heat-conducting mud. The heat-conducting mud comprises a composition composed of a potassium silicate solution, a sodium silicate solution, a dispersing agent BYK-190, Guangxi white mud, water-soluble fibers, crystalline flake graphite # 100, crystalline flake graphite # 50 and artificial high-power graphite according to the amount ratio of (25-27): (25-27): (0.3-0.4): (1.5-2): (0.8-1): (30-32): (8-10): (3-5). According to the invention, the binder is modified by the tackifier of the self-made binder, so that the stability of the high-temperature-resistant heat-conducting mud is enhanced, the high-temperature and low-temperature strain resistance is improved, the high-temperature-resistant heat-conducting mud has better strain adhesion in environments with high temperature, large temperature change and strong corrosivity, the heat-conducting mud is not easy to leak and pulverize, and the stability is good; the high temperature resistance and corrosion resistance of the heat preservation and insulation layer are improved by adjusting the formula, various complex working conditions in ascending pipe heat exchange equipment can be met, and tar hanging is prevented. And the heat exchange efficiency of the coking riser heat exchange equipment is improved.
