How Does a Manufacturer's Constant Temperature Curing Kiln Affect Product Quality?

The constant temperature curing kiln is key equipment in GRC production, directly affecting product strength development, durability, and consistency. Qinglong Group has introduced an intelligent curing system with temperature control accuracy of ±2℃ and humidity ≥95%, raising the GRC strength compliance rate to 99.5% and keeping the coefficient of variation within 5%. This fine control, by optimizing the hydration reaction, ensures stable product performance and lays the foundation for project success.

Temperature control determines strength development. Curing is typically carried out at 60-80℃ for 24-48 hours to promote C-S-H gel formation. At its Nanning production base, Qinglong Group applies zoned temperature control to ensure even heating of components of different thicknesses. Excessively high temperatures may cause delayed ettringite formation, affecting long-term performance; temperatures that are too low slow strength development. A scientific curing regime ensures full strength development, with 3-day strength reaching 70% of the 28-day strength. This control improves production efficiency and shortens delivery times.

Humidity management prevents cracking. Curing humidity is kept at a high level to reduce drying shrinkage cracks caused by moisture evaporation. Qinglong Group uses a spray humidification system with humidity fluctuation ≤3%. Slow cooling after curing avoids thermal stress. These measures improve product durability, with freeze-thaw resistance reaching F300 and above. Constant temperature curing is a critical link in quality assurance.
