Avoiding the deformation of ceramic fiberboard is an important part of ensuring its long-term effective use and aesthetics. Here are some specific methods that can help us effectively prevent the deformation of ceramic fiberboard:
1. Control the moisture content
Reduce and homogenize moisture: Ceramic fiberboard is prone to deformation in the case of uneven water content or too high moisture. Therefore, its moisture content should be strictly controlled to ensure that it remains dry during production, storage and use. With proper drying, the moisture content reaches a uniform and low level, which can effectively reduce the weight of the fiberboard, thereby reducing the risk of deformation.
2. Optimize stacking and storage
Stacking and pressing heavy objects horizontally after hot pressing: After the ceramic fiberboard is hot-pressed, the heavy objects should be stacked horizontally and pressed to keep its shape stable. This ensures that the fiber orientation of the fiberboard is parallel to the direction of dry shrinkage and wet expansion of the substrate, thus reducing deformation due to uneven stress.
Storage environment requirements: Ceramic fiberboard should be stored in a cool, dry and well-ventilated environment, avoiding direct sunlight and high temperature and humidity conditions to reduce the influence of environmental factors on its shape.
3. Improve the production process
Reduce the amount of urea-formaldehyde resin glue: In the production process, appropriately reducing the amount of urea-formaldehyde resin glue can make the glue layer softer, thereby improving the hot pressing conditions and reducing the deformation caused by the hardening of the glue line.
Optimize raw materials and processes: using jet fibers (short, fine, easy to break and mix) as raw materials, and adding a certain proportion of binders and filler-grade additives, after full dispersion, stirring, vacuum dehydration and drying and other processes, can ensure that the structure of fiberboard is uniform and dense, and improve its ability to resist deformation.
Fourth, pay attention to the use and installation
The center is slightly loose when pasting: when pasting the ceramic fiberboard, the center part can be slightly loosened to avoid deformation caused by stress concentration caused by too tightness.
Reasonable cutting and installation: In the process of use and installation, the fiberboard should be reasonably cut according to the actual needs, and the installation should be firm and smooth, so as to avoid deformation caused by uneven local force.
5. Regular inspection and maintenance
Regular inspection: Regularly inspect the ceramic fiberboard, find and deal with deformation, cracking and other problems in time, and prevent the problem from expanding and affecting the use effect.
Maintenance: During use, pay attention to avoid heavy objects being pressed directly on the fiberboard, so as not to cause damage and deformation. At the same time, keep the use environment clean and dry, and prolong the service life of fiberboard.
In summary, by controlling the moisture content, optimizing the stacking and storage, improving the production process, paying attention to the use and installation, and regular inspection and maintenance, we can effectively avoid the deformation of ceramic fiberboard and ensure its long-term effective use and aesthetics.
