Frequently Asked Questions
Why choose natural gas drying over electric infrared for these boards?
Natural gas provides convective heat that penetrates deeply into the porous structure of cement fiber boards, ensuring moisture is removed from the core. Electric IR often only heats the surface, risking blistering or incomplete curing.
Can this line handle both very small and large panel sizes?
Yes, through customization. The conveyor width, fixture design, and spin coater chuck size can be customized to accommodate a wide range of panel sizes.
What is the typical lead time for such a customized line?
The lead time is typically 16-20 weeks from order confirmation, including detailed engineering, manufacturing, factory testing, and packing.
