Abstract

The invention relates to the technical field of making man-made fiberboards, in particular to a production method of ultrafine formaldehyde residual fiberboards. The production method of the fiberboard comprises the following steps: preparing adhesive - making wood fiber - sizing - drying - paving and pre-pressing - hot pressing - finished product. The present invention utilizes forest felling residues, wood processing residues, or bagasse as raw materials to produce fiberboards, turning waste into wealth, and effectively realizing the full utilization of wood resources; The residual adhesive is environmentally friendly, safe, and has good water resistance and strong bonding strength; the fiberboard produced with this adhesive has almost no formaldehyde residue and strong bonding force; the content of harmful substances to the human body is low , almost none, reducing the harm to the human body, and the internal structure of the board is uniform, the density is moderate, the dimensional stability is good, the quality is stable, and the service life is long.

Description

technical field

[0001] The invention relates to the technical field of manufacturing fiberboards for decoration materials and building materials, in particular to a production method for fiberboards with ultrafine formaldehyde residues. Background technique

[0002] With the progress of society and the continuous improvement of human awareness of environmental protection, man-made panels are gradually replacing natural wood in areas such as architectural decoration. Density board, also known as fiberboard, is a man-made board made of wood fiber or other plant fiber and applied with urea-formaldehyde resin or other suitable adhesives. According to its density, it can be divided into high-density board, medium-density board and low-density board. MDF is soft, impact-resistant, and easy to reprocess. It is a good material for making furniture abroad. However, because the national standard for high-density boards is several times lower than the international standard, the use q...
