Chemical Safety of Furniture Products

Abstract

At present, technical regulations are adopted for furniture products of various types, establishing the protection of human health from the influence of harmful substances in the parts and assemblies of wood products and wood materials. The technical regulation adopted the requirements for ensuring chemical safety in the design and manufacture of furniture. The technical regulation is based on the condition of furniture products, eliminating the risk of harm to human health due to exceeding the maximum permissible concentration of harmful chemicals in indoor air. Such substances include free formaldehyde, migrating from the volume of chipboard and glue interlayers when gluing and veneering furniture parts and assemblies. Harmful chemicals are vapor-gas mixtures of solvents, the migration of which is observed from solid lacquer membrane of protective and decorative coatings of parts and components of furniture into the indoor air environment. These chemicals are present in the construction and auxiliary materials in the development of furniture. It is desirable that manufacturers of furniture products determine in advance, at the stage of its design, the level of safety when using certain raw materials. For this purpose, a technique is proposed that allows us to determine the concentration of harmful substances in the air of the premises with the selected materials, design and manufacturing technology of furniture products. Preliminary calculations based on the proposed method, allows us to determine the life of the furniture, in which the harmful substances migrating into the air environment of the premises will be within the permissible concentrations. This allows certifying the manufactured furniture products for chemical safety with the assignment of certain quality parameters. The proposed technique may be useful for enterprises focused on the production of furniture products.

Research on the elimination of low-concentration formaldehyde by Ag loaded onto Mn/CeO2 catalyst at room temperature

“…7 Indoor formaldehyde pollution caused by indoor decoration seriously endangers people's health, which has attracted widespread attention from scholars at home and abroad and has become one of the hotspots of research. The main sources of formaldehyde in the indoor environment are adhesives in decoration materials, 8 glue in furniture, 9 whitewashing materials 10 and daily necessities. 11 Up to now, methods used for the removal of formaldehyde from indoor air mainly include ventilation methods, 12 adsorption methods, 13,14 low-temperature plasma methods, 15 photocatalysis methods, 16 and catalytic oxidation methods.…”

A Study on Organic Chemicals in Children's Room Furniture

“…Bu kimyasallar arasında mobilya üreticileri ve satıcıları için kimyasal tehlikelere ve alerjik hastalıklara neden olabilen solventler, formaldehit ve fenol bulunmaktadır [26]. Mobilyaların koruyucu ve dekoratif kaplamaları, iç mekân hava ortamına geçebilen solventlerin buhar-gaz karışımlarını da yayabilir [27]. Mobilya üretiminde kullanılan bazı malzemeler, vernikler ve ahşap kompozit ürünlerden iç mekân hava kalitesini etkileyebilecek kimyasal maddeler yayabilir [28].…”
