هل تتشقق منتجات GRC بسهولة؟ تقرير بحثي حول تقنية مقاومة التشقق من مصنعي GRC

Cracking is a common issue with GRC products, but it can be effectively prevented through technical measures. Qinglong, a GRC manufacturer, has achieved remarkable results in crack resistance through 28 years of technical expertise, keeping its product cracking rate at a low level within the industry.

In terms of material formulation, Qinglong uses low-alkali cement and alkali-resistant glass fibres to improve crack resistance at the source. By optimizing the mix ratio, it reduces the water-binder ratio and increases density. The addition of polypropylene fibres forms a secondary reinforcement network that effectively suppresses crack formation. In the curing process, steam curing is adopted with controlled heating and cooling rates to reduce thermal stress. This comprehensive technical solution was successfully applied in the Wuhan Hanxiu Theatre project, which has shown no cracking in 10 years of use.

Design Measures for Crack Prevention

Crack resistance is improved by reasonably configuring reinforcing ribs. Panel dimensions are controlled, and appropriate expansion joints are provided. In the Shenzhen Yirui Biotechnology Building project, this design effectively prevented cracks caused by thermal stress.

Key Points for Crack Prevention During Installation

Reserve space for deformation during installation to avoid stress concentration. Use flexible materials for joint treatment to accommodate deformation. Qinglong provides professional installation guidance to ensure construction quality.

Usage and Maintenance Recommendations

Conduct regular inspections to promptly identify and address fine cracks. Avoid external impacts and maintain normal use. Qinglong provides comprehensive after-sales service to help customers maintain their products.

Through systematic measures, the cracking problem of GRC products can be effectively controlled.
