GRC Production Process Technology Analysis: Qinglong GRC Process Innovation

GRC production processes mainly include three major categories: spray-up molding, premix casting, and manual mesh-laying. The spray-up process features directional fiber distribution and high strength (flexural strength ≥18MPa), suitable for complex shapes; the premix process is highly efficient with good surface quality, suitable for flat panels; the mesh-laying process is simple and flexible, suitable for small batches. Qinglong GRC has innovatively developed a vacuum spray-up process with density ≥98%, strength increased by 20%, and durability of over 50 years.

Process comparison: The spray-up process requires large investment but offers the best performance; the premix process is highly efficient and suitable for mass production; the mesh-laying process requires small investment but has large quality fluctuations. A certain art center's double-curved curtain wall adopted Qinglong GRC's vacuum spray-up process, achieving complex shapes, strength that meets standards, and an exquisite appearance.

Characteristics of the Spray-up Process

Directional fiber reinforcement, high flexural strength; layered structure, good impact resistance; capable of producing complex shapes; large investment, high technical requirements. The preferred process for high performance.

Advantages of the Premix Process

High production efficiency, suitable for batch production; good surface quality, high finish; random fiber distribution, isotropic properties; moderate investment, easy operation. An economical and efficient process.

Applications of the Mesh-laying Process

Manual operation, simple and flexible; small investment, suitable for small batches; continuous fibers, crack control; large quality fluctuations, low efficiency. A choice for personalized small-batch production.
