Problems solved by technology

However, the fibers used in the production of fireproof insulation boards have a high water absorption rate after being needled into felt, and there is still a large amount of water remaining inside the needle felt after the process of dipping and squeezing; and due to the thermal conductivity of the fiber itself Therefore, the subsequent drying process usually requires a relatively long time of baking at a higher temperature, which is very time-consuming and energy-consuming, and it is difficult to control the moisture content in the needle felt within an ideal range after baking, and then As a result, the quality of the fireproof and thermal insulation panels produced by the subsequent hot pressing molding process fluctuates greatly, the yield is low, and the cost is high
