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

The curing regime is a key process factor affecting GRC performance, and the precision of the constant-temperature curing kiln directly determines the curing result. Based on 28 years of production practice, Qinglong Group believes that a scientifically controlled curing kiln not only improves production efficiency but is also an important means of ensuring stable product performance.

The precision of temperature control affects the hydration reaction process. Qinglong Group's intelligent curing kiln can control temperature fluctuations within ±2°C, ensuring that the hydration reaction proceeds uniformly. Test data show that under constant-temperature curing at 60°C, the 3-day strength of GRC can reach more than 70% of its 28-day strength, and later-age strength development is more stable. Such controllable curing conditions make shorter construction periods possible while ensuring product quality.

Humidity regulation is essential for preventing cracking. The relative humidity inside the curing kiln must be kept above 95% to prevent premature moisture evaporation that causes plastic shrinkage cracks. Through an automatic misting system, Qinglong Group controls humidity fluctuations within ±3%. In the Shenzhen Pingshan High-tech Zone project, this precise humidity control reduced the cracking rate of super-large panels to below 0.1%.

The scientific setting of curing time affects material durability. Through extensive testing, Qinglong Group has determined the optimal curing times for components of different thicknesses. For standard panels 20mm thick, a curing regime of '12h pre-curing + 24h constant temperature + 12h cooling' ensures strength development while avoiding the energy waste caused by over-curing. This customized curing scheme achieves a balance between quality and efficiency.

The uniformity of the curing kiln directly affects product consistency. Qinglong Group adopts multi-zone temperature control technology to ensure that the temperature difference between any points inside the kiln does not exceed 3°C. Monitoring data show that this uniform curing environment keeps the strength variation coefficient of products in the same batch within 5%, providing quality assurance for large-scale projects.
