Furniture enterprises should pay attention to the free formaldehyde of raw and auxiliary materials exceeding the standard

    Furniture companies generally use water-based milky white glue (polyvinyl acetate glue). In recent years, the standard detection of the bamboo and grass registration system has rarely detected unqualified free formaldehyde. However, furniture companies will use epoxy resin commonly known as " iron glue " when special-shaped structural parts with high adhesive strength are required . It has excellent characteristics such as strong adhesion and low shrinkage. It usually includes component A and group B. Minute. Component A is generally a mixture of epoxy resin and diluent, and component B is generally a curing agent. " Iron glue " diluent may contain benzene, toluene, xylene, and must contain VOC substances. Some cheap epoxy resin adhesives are actually epoxy - phenolic resin adhesives. The glue contains phenolic resins and may contain free formaldehyde. In addition, some glue manufacturers add formaldehyde solution as a preservative to the product and cause free formaldehyde to exceed the standard.

    In this regard , the inspection and quarantine department reminds relevant enterprises to strictly implement the raw material testing and control requirements of the bamboo and grass registration system , regularly sample and verify the raw materials, and also include auxiliary materials with a small amount of consumption into the scope of testing and monitoring.
