摘要

In the Department of Environment Protection in the Wood Technology Institute we carried out research of emission of Volatile Organic Compounds from materials used in furniture production. VOC emission research from lacquered veneers made from nitrocellulose and acrylic lacquer put on glass board showed minimal higher total TVOC concentration observed in air collected from the chamber filled with lacquered boards comparing with its concentration in air supplied to the chamber. Similar low TVOC concentration was observed in research of basic wood based materials like: chipboard, veneered and laminated chipboard, MDF board and plywood. Coatings from chemsetting and polyurethane lacquer were emitted higher amounts of volatile organic compounds. Our research confirmed that lacquers play a main role in VOC emission from wood-borne materials applied in furniture production.
