Due to the variety of indoor units, consumers like to choose customized furniture, which is more suitable for the house structure. The customized furniture is mainly divided into two categories: one is the bare board furniture made of joint board (tooth joint board), blockboard (big core board) and plywood (multi-layer board and solid wood multi-layer board); the other is panel furniture made of blockboard or plywood (commonly referred to as "paint free board" or "ecological board") with veneered veneer.

情况1：不作任何处理的家具内侧是长期甲醛污染源

Case 1: the interior of furniture without any treatment is the source of long-term formaldehyde pollution

家具外表面使用了经过处理的装饰面板，或者喷涂油漆，家具内部不作任何处理，为细木工板、胶合板等素板的裸露面，甲醛挥发无任何阻挡，是的长期甲醛污染释放源。如图中的床箱和储物柜。

The exterior surface of the furniture has been treated with decorative panels or sprayed with paint, and the interior of the furniture is not treated. It is the exposed surface of plain board such as Blockboard and plywood. Formaldehyde volatilization is not obstructed, which is the biggest long-term formaldehyde pollution emission source. The bed box and locker are shown in the picture.

情况2：内侧贴了PVC饰面材料，要通过检测确认是否为污染源

Case 2: PVC facing material is pasted on the inner side, and the pollution source shall be confirmed by testing

有些家具内侧装修时贴了PVC装饰纸，但因PVC封闭效果不佳，人造板中的游离甲醛还是能够挥发出来的。

Some furniture interior decoration pasted with PVC decorative paper, but because of the poor sealing effect of PVC, the free formaldehyde in wood-based panel can still volatilize.

贴了PVC饰面材料是否还是甲醛污染源，就需要检测了。室内气温在23℃以上，家具内检测结果是0.4-0.6毫克以上，毫无疑问就是长期甲醛污染源。

Whether the PVC facing material is still the source of formaldehyde pollution needs to be tested. The indoor temperature is above 23 ℃, and the detection result in furniture is more than 0.4-0.6 mg, which is undoubtedly a long-term formaldehyde pollution source.

注：指接板常常被误以为是没有甲醛污染的实木板，实际上是甲醛污染相对较少的人造板。指接板用胶量比细木工板少，其甲醛释放量接近细木工板的一半。

Note: it is often mistaken for solid wood panel without formaldehyde pollution, but in fact it is wood-based panel with relatively less formaldehyde pollution. The amount of glue used in finger joint board is less than that of blockboard, and its formaldehyde emission is close to half of that of blockboard.

用免漆板制作的板式家具

免漆板制作的家具与PVC饰面家具一样，需要通过检测来验证是否为甲醛污染源。

The furniture made of paint free board and PVC decorative furniture need to be tested to verify whether it is the source of formaldehyde pollution.

另外免漆板有“单饰面”（只有一面贴了饰面皮，另一面没有贴，胶合板或木工板直接暴露）和“双饰面”之分，如果是单饰面，更好在装修时用强力除醛剂处理没有饰面的一侧。

In addition, the paint free board can be divided into "single facing" (only one side is pasted with veneer, the other side is not pasted, plywood or wood board is directly exposed) and "double facing". If it is a single finish, it is better to use strong formaldehyde remover to treat the side without finish during decoration.
