Methods to Prevent Deformation of Ceramic Fiber Boards
Ceramic fiber boards are manufactured by combining ceramic fiber cotton with appropriate amounts of organic and inorganic binders. Improper handling can lead to deformation, which affects both performance and appearance. To minimize deformation, the following methods are recommended:
1. Reduce and Evenly Distribute Moisture Content
Lowering the moisture content and ensuring uniformity reduces the board’s weight and minimizes uneven shrinkage.
2. Horizontal Stacking After Hot Pressing
Stack boards horizontally after hot pressing and place weights on top. Align the fiber direction parallel to the base material’s shrinkage direction to reduce dimensional changes from drying or humidity.
3. Slight Looseness During Adhesive Installation
When gluing ceramic fiber boards, leave the central area slightly loose to accommodate expansion and contraction.
4. Optimize Binder Usage and Hot Pressing Conditions
Reduce the amount of urea-formaldehyde resin binder to maintain flexibility, and adjust hot pressing conditions to prevent excessive stress that may cause warping.
Summary
Preventing deformation requires careful attention throughout production, storage, and usage. Proper handling increases product lifespan, maximizes utilization, and avoids unnecessary energy and labor costs.
