The percentage by weight of dimension is 25~40%.
Preferable technical scheme is that the raw fibre of the first felt is mixed by flaxen fiber, doughnut and principal fiber,
Wherein the percentage by weight of flaxen fiber is 25~40%, and the percentage by weight of doughnut is 5~10%.
Preferable technical scheme is that the raw fibre of the 3rd felt is mixed by flaxen fiber, doughnut and principal fiber,
Wherein the percentage by weight of flaxen fiber is 15~30%, and the percentage by weight of doughnut is 5~10%.
The advantages of the present invention are：
Sandwich type puncture felt hot-pressed board of the present invention is simple in construction, punctures and is hot bonding by using three layers of compound felt
Mode, make felt interlayer stable connection and one-shot forming, the use of non-adhesive, ensures follow-up sheet material in production process of plate
Formaldehyde zero-emission during use, doughnut can guarantee that the soundproof effect of sheet material.
