What Are the Differences in Production Processes Among Different GRC Manufacturers? A Comparative Analysis of Qinglong GRC Process Technology

Differences in GRC production processes directly affect product quality and performance. Through 28 years of technical accumulation, Qinglong GRC has developed a unique production system with clear advantages in key aspects such as batching precision, fiber distribution, and curing control.

In terms of process comparison, Qinglong adopts an improved spraying process: fibers are evenly distributed in three dimensions through a specialized spray gun, with fiber volume content controlled at 4.5%-5%; vacuum dewatering reduces the moisture content to 18%; and a stepped curing regime ensures optimal strength development. This process enables products to achieve a flexural strength of 18-22MPa with a coefficient of variation controlled within 5%, far superior to products made by conventional processes.

Batching Process Differences

Quality manufacturers use automatic batching systems with 0.1% precision; ordinary manufacturers rely on manual batching, with errors up to 5%. This difference affects mix proportion accuracy.

Molding Process Differences

The spraying process offers good fiber orientation and suits complex components; the premix process is highly efficient and suits flat panels. Qinglong optimizes the process according to product characteristics.

Different Curing Regimes

Standard curing reaches the target strength in 28 days; steam curing achieves 70% strength in 7 days; Qinglong's intelligent curing balances efficiency and quality.

Testing Standard Gaps

Quality manufacturers perform online testing on 100% of products; ordinary manufacturers have low sampling ratios. This gap affects quality consistency.

Process capability needs to be verified through evidence. It is recommended to inspect production lines on site to understand process details. Qinglong GRC welcomes customers to visit its production base for an in-depth understanding of its process advantages.
