Panel machinery tells us, pre-press in the wood-based panel production process plays an important role, the role of pre-press pre-press, today we come to understand the purpose of the pre-press pre-press.
The purpose of the pre-press preloading three main aspects, the first is to exclude the slab in the air, a lot of hot air to prevent the escape broke through the slab; then the slab has a certain solidity to improve their support strength so as not to loose due to vibration or breakage during transportation; final aim is to reduce the bulkiness of the slab thickness can be reduced so that we can press to open the file.
After the pre-press pre-press, reduce the slab than two-thirds - three-quarters of the original, however, you want to stretch the width direction of the slab 5% -7%, this would require our attention.
