Problems solved by technology

[0003] According to previous engineering cases, the anti-corrosion process of the chimney flue after wet desulfurization is often constructed in the form of a combination of acid-resistant cement and vitrified bricks, but this construction process takes a long time and often leaks or due to time For a long time, vitrified tiles cannot stick and fall off, causing safety hazards

Abstract

The invention discloses high temperature-resistant corrosion-resistant cement gum and a construction method thereof. The high temperature-resistant corrosion-resistant cement gum comprises a component A and a component B. A ratio of the component A to the component B is 18-23: 0.8-1.2. The component A is a high temperature-resistant corrosion-resistant polymer and comprises 38.0-47.2wt% of silica gel, 8.8-10.3wt% of silicone oil, 2.1-3.9wt% of fumed silica, 1.8-2.7wt% of activated zinc oxide, 11.8-14.5wt% of active silica micropowder, 3.5-5.2wt% of precipitated silica, 12.0-13.5wt% of active aluminum hydroxide micropowder, 3.3-5.3wt% of glass-ceramic powder and 5-7.5wt% of diatomite. The component B is a coagulator and comprises 30-35wt% of silicone oil and 65-70wt% of tetrapropoxysilane. The high temperature-resistant corrosion-resistant cement gum has high temperature resistance, can prevent corrosion produced by various acid and alkali mediums and has good tensile strength and excellent penetration resistance.

Description

technical field [0001] The invention relates to the field of anti-corrosion technology, in particular to a high-temperature-resistant anti-corrosion mortar and a preparation method thereof. Background technique [0002] In my country, coal-fired boiler flue gas is one of the most important sources of air pollution and has become the primary goal of environmental governance. In 2005, my country's sulfur dioxide emissions reached 25.5 million tons, and the total emissions have surpassed that of Europe and the United States, ranking first in the world. Excessive flue gas emissions make the originally valuable sulfur resource a huge pollution source that endangers the environment. Therefore, it is imperative to remove sulfur dioxide in the tail gas in the flue gas, and the combination of various desulfurization processes (dry desulfurization process, semi-dry desulfurization process, wet desulfurization process, etc.) has the highest efficiency for boiler tail gas desulfurizati...
