Mildew and anti-mildew treatment of MDF
Mildew cause: MDF is a kind of density board, density board is also known as fiberboard, is made of wood fiber or other animal fiber as raw materials, the application of urea formaldehyde resin or other applicable adhesives made of natural board. The medium fiber sheet is loose, easy to be damp, and the water is not well controlled. The glue used in the production of MDF is urea-formaldehyde resin, one of the raw materials is formaldehyde, formaldehyde has a good killing effect on staphylococcus, mold, yeast, etc., but for a substance with high toxicity, the environmental protection requirements of MDF are improved, the release of formaldehyde is limited, the use of environmentally friendly glue or production to improve its utilization or by removing formaldehyde process, in short, It is necessary to reduce the content of free formaldehyde in MDF, which also makes it more prone to mold problems.
