A New Technology for Dry Glue-Free Hardboard Fiberboard Production

The problem of wastewater pollution which has long plagued fiberboard  Hardboard production is expected to be solved thoroughly by new technology.

This new technology is the production technology of dry glue-free rigid fiberboard Hardboard.

There are wet and dry methods for fiberboard  Hardboard production in China. Wet fiberboard  Hardboard production has two major drawbacks: pollution caused by waste water discharge to the environment and netting marks on the back of products, which seriously restricts the development of fiberboard Hardboard production and the market competitiveness of products. Several domestic dry process manufacturers also have to apply phenolic resin adhesives to affect their development. Dry-process adhesive-free rigid fiberboard  Hardboard production technology has changed the present situation of dry-process adhesive. Under suitable technological conditions, only about 1% paraffin is needed to produce adhesive-free rigid fiberboard Hardboard by dry-process on ordinary dry-process fiberboard  Hardboard production line, and the product is smooth on both sides. The physical and mechanical properties of the product meet the requirements of national standards for rigid fiberboard Hardboard. 。 In addition, due to the adoption of low temperature cooking and hot pressing technology, the new technology matches the process required for wet production, which creates conditions for the technological transformation of wet fiberboard  Hardboard industry in China.
