AI Technical Summary

Technical Problem

High-quality wood pulp fibers are expensive and unstable in supply, resulting in high production costs and great environmental impact of fiber-reinforced cement boards.

Method used

Short cotton wool fibers were used to replace some wood pulp fibers, and by adjusting the formula and process steps, fiber cement boards with a density of 1.29-1.68kg/m3 and a flexural strength of 9.8-19.97MPa were prepared.

Benefits of technology

It significantly reduces production costs, reduces the consumption of forest resources and the environmental impact, while maintaining the flexural strength comparable to traditional products, meeting the high standards of the construction industry.
