The design emphasizes corrosion resistance, crack-following ability, and measures to suppress pinholes!
The phenomenon of concrete corrosion in sewer facilities is known to occur due to the generation of sulfides by sulfate-reducing bacteria in sewage sludge. Hydrogen sulfide gas, which is released from the liquid phase to the gas phase, dissolves in condensation water and progresses due to sulfuric acid produced by sulfur-oxidizing bacteria. Even when a protective material is coated, corrosion progresses from areas where pinholes or cracks have formed in the protective material, which cannot keep up with the cracking, leading to breakage or fissures. The "Airtight Method" is designed with a focus on corrosion resistance, crack-following ability, and measures to suppress pinholes. In sewer facilities, we propose measures for reducing lifecycle costs and extending service life based on functions and performance that meet the required specifications and long-term durability records. 【Features】 ■ Maintains performance over a long period ■ Deterioration can be visually assessed, making repairs easy ■ High strength and flexibility enhance crack-following ability ■ High corrosion and chemical resistance, capable of handling special wastewater inflows *For more details, please refer to the PDF materials or feel free to contact us.
