AI Technical Summary
Traditional setting agents used in the mineral wool industry contain formaldehyde, which leads to environmental and health problems. Furthermore, existing setting agents need to be prepared on-site, resulting in discontinuous production, high costs, and unstable quality.
A single-component sizing agent with long-term stability was prepared by mixing formaldehyde-free adhesive with compatible reactive silane coupling agents, water-repellent agents, and dust-proofing oils, and laboratory testing methods were provided to assess its service life.
This environmentally friendly single-component setting agent has a shelf life of over 6 months, solving the environmental problems of traditional setting agents, improving production continuity and quality stability, and reducing testing and switching costs.
