How Does a Manufacturer's Constant-Temperature Curing Kiln Affect Product Quality? An In-Depth Analysis of Qinglong's GRC Curing Process

The constant temperature curing kiln, through precise control of temperature (fluctuation ≤±2℃) and humidity (≥95%RH), increases GRC strength by 20%-30% and improves durability by more than 50%. Qinglong GRC's intelligent curing kiln adopts a PLC automatic control system to achieve precise control throughout the entire process of heating, constant temperature, and cooling, ensuring a product strength variation coefficient ≤5%.

Curing regime studies show that: constant temperature curing at 20-25℃ for 3 days achieves 70% of the 28-day strength; constant temperature curing at 40-45℃ for 1 day achieves 80% of the 28-day strength; however, excessively high curing temperature (>60℃) causes later-age strength regression. Qinglong GRC adopts a stepped curing regime: pre-curing at 20℃ for 12h → heating to 40℃ over 8h → constant curing at 40℃ for 24h → natural cooling; this regime ensures stable product strength and excellent durability.

Impact of Temperature Control Precision

With temperature fluctuation ≤±2℃, the strength variation coefficient is ≤5%; with fluctuation >±5℃, the variation coefficient is ≥15%; this impact is very significant.

Importance of Humidity Control

Humidity ≥95% avoids water-loss cracking; humidity <80% reduces strength by 20%; this importance must be taken seriously.

Curing Time Optimization

A constant temperature time of 24-48h yields the best results; too short a time results in insufficient strength; too long reduces efficiency; this optimization is critical.

Balancing Energy Consumption and Quality

Intelligent control saves 30% energy; quality stability is improved; this balance achieves a win-win.

Scientific curing determines product quality. Qinglong GRC's advanced curing equipment guarantees excellent product performance.
