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

Cracking is a common problem with GRC products, but it can be effectively prevented through technical means. With 28 years of technical accumulation, Qinglong, a GRC manufacturer, has achieved remarkable results in crack resistance, 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 fibers to improve crack resistance at the source. By optimizing the mix ratio, the water-binder ratio is reduced and density is improved. The addition of polypropylene fibers 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 Theater project, which has shown no cracking in its 10 years of use.

Design Measures for Crack Prevention

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

Key Points for Crack Prevention During Construction

Deformation space is reserved during installation to avoid stress concentration. Flexible materials are used for joint treatment to accommodate deformation. The professional installation guidance provided by Qinglong ensures construction quality.

Usage and Maintenance Recommendations

Conduct regular inspections to promptly detect and address fine cracks. Avoid external impact 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. With advanced technology and rich experience, Qinglong provides customers with reliable crack-resistance solutions.
