Ceramic fiber boards are artificial boards made from ceramic fiber cotton with added organic binders and inorganic adhesives. If these boards deform due to improper operation or usage, it not only affects their performance but also compromises their appearance.
01 Reduce and Uniformize Moisture Content
Lowering the moisture content of the ceramic fiber board and ensuring it is evenly distributed can help reduce its overall weight and minimize the risk of deformation.
02 Level Stacking After Hot Pressing with Weight Applied
After the hot pressing process, stack the boards horizontally and place weights on top. Align the fiber direction of the boards parallel to the direction with minimal shrinkage and expansion of the base material.
03 Slightly Looser Central Area During Adhesive Bonding
When applying adhesive to the ceramic fiber board, ensure the central part is slightly looser to accommodate potential expansion or contraction.
04 Reduce Urea-Formaldehyde Resin Usage and Optimize Hot Pressing Conditions
During production, decrease the amount of urea-formaldehyde resin used to keep the adhesive layer soft. Additionally, improve the hot pressing conditions to enhance the board's stability.
Conclusion
To effectively prevent deformation of ceramic fiber boards, it is essential to handle every step of production, storage, and usage with care and attention. Proper practices will extend the product's service life, improve its utilization rate, and avoid unnecessary waste of energy and manpower.
