Ahşap Esaslı Levhalarda Formaldehit Emisyon Problemleri ve Çözüm Önerileri

Abstract

Ahşap kompozit levhalar dünyada yapı malzemesi olarak inşaat ve dekorasyonda, köprü ve iskele yapımında, taşımacılık sektörü ve mobilya üretiminde yaygın şekilde kullanılmaktadır. Formaldehit içerikli tutkallarla üretilen ahşap kompozit paneller ve bunlardan üretilen malzemelerden salınan formaldehit standartların üzerinde olması çevre ve insan sağlığını olumsuz etkilemektedir. Formaldehit emisyonu; ortamdaki konsantrasyona, maruz kalma süresi ve şekline bağlı olarak deri, göz ve solunum sisteminde ciddi alerjik reaksiyonlara, bağışıklık sistemini zayıflatıcı, kanseri tetikleyici sağlık sorunlarına neden olmaktadır. Bu bağlamda ahşap kompozit panellerin üretimi başta olmak üzere formaldehit içerikli tutkalların üretiminde kullanılan formaldehitin standart sınırlar içerisinde olması konusunda yasal düzenlemeler yapılarak uygulamaya konulmalı ve gerekli denetimler yapılmalıdır.

Formaldehyde Emission Problems and Solution Recommendations on Wood-Based Boards

Abstract

Wood composite panels are widely used in building, decoration, bridge, pier construction, transportation sectors and furniture production in the world. Formaldehyde which is found from formaldehyde containing adhesive bonded wood composite panels and the wood products above the standard amounts released has a negative impact on the environment and human health. Formaldehyde emission; Depending on the concentration in the environment, exposure time and shape, causes severe allergic reactions in the skin, eye and respiratory system, weakens the immune system, and causes cancer like health problems. In this context, it is concluded that legal arrangements should be prepared for formaldehyde usage, which is used in the production of formaldehyde-containing adhesives, especially wood composite panels, and necessary controls should be made if the adhesives are prepared within the standard limits.
