The most common material for the production of furniture around the world has long been chipboard - chipboard. Wardrobes are made of this material - the most popular and comfortable furniture of our time. Chipboard is a material made by hot pressing specially prepared wood particles and a binder. The raw materials for this material can be: specially chopped wood chips; sawmill waste; chips obtained in planing production.
Phenol-formaldehyde, urea-formaldehyde and other resins are used as a binder. And it is the composition of the binder and its environmental friendliness that are an insurmountable obstacle for some buyers of wardrobes. Very often people ask the question - are chipboard plates harmful to health? Indeed, the composition of the binder (glue) includes a certain amount of special preservatives that can release formaldehyde in small quantities. Any manufacturer of furniture, including wardrobes, will say that it is impossible to preserve the original state of the material without preservatives. Preservatives prevent the reproduction of microorganisms in the processed raw materials. It is necessary to dwell in more detail on the designation of what formaldehyde is. Everyone remembers biology lessons at school, and jars of biological material behind the glass cabinets.
Formalin, a formaldehyde solution, was used as a preservative there. It is a mistake to believe that this gas (formaldehyde is a gas) is used only for the production of chipboard, and, consequently, in furniture production. This chemical compound is used in the production of various kinds of plastics, clothing and shoes made of leather, mineral fertilizers, etc. Formaldehyde can be released even certain types of paper and rubber, as well as disposable plastic tableware. Of course, everything is not as scary as customers who want to buy wardrobes assume. Fiberboard slabs, which correspond to the E1 emission level, emit formaldehyde only slightly more than solid wood. If you purchase wardrobes made of E1 chipboard, be sure that such furniture will not bring any harm to your health. Wardrobes made of plate with E1 emission are allowed for use in children's and medical institutions. The European norm of formaldehyde E1 emission is 8 mg/100 g of dry weight with an average value of 6.5 mg. The Russian norm is 10mg/100g. To make sure of the absolute safety of chipboard wardrobes, the buyer should make sure that all the surfaces of the plate are covered with a protective film, and all sections are sealed. king567 casino apk download
