The formaldehyde in the indoor wooden doors of these brands exceeds the standard!

Yesterday, Chongqing Municipal Bureau of Quality Supervision issued the announcement of the first phase product quality supervision and spot check in 20 17-the announcement of indoor wooden door product quality supervision and spot check. This time, 226 batches of products from 186 production enterprise were randomly selected, and items such as moisture content, appearance requirements, limit of harmful substances, formaldehyde emission and so on were inspected.

The results of spot check show that 14 batches of products of Yating, Wei Zi, Mu Jiangjun and Jiayu brands were found to be unqualified, and the unqualified rate of spot check was 6.2%. The unqualified items are mainly moisture content and formaldehyde emission. Among them, the formaldehyde emission of 12 batch products was found to exceed the standard, and the formaldehyde emission of individual products was more than twice the standard value.

Moisture/water content

The moisture content of two batches of indoor wooden doors exceeded the standard.

The moisture content of indoor wooden doors refers to the percentage of moisture content in the weight of wooden doors, which reflects the ability of wooden doors to resist moisture erosion in the air under humid and low temperature conditions. After testing, it was found in this supervision and spot check that the moisture content of two batches of indoor wooden doors exceeded the standard.

"The high moisture content of indoor wooden doors will lead to serious quality problems such as deformation and warping." Deng Min, an engineer of the Light Industry Center of the Municipal Institute of Metrology and Quality Inspection, said that the moisture content of indoor wooden doors is not up to standard, which will not only affect the normal use, but also lead to the phenomenon of "whitening" of indoor wooden doors, which will affect the painting quality of wooden doors.

Formaldehyde emission

12 batches of indoor wooden doors have formaldehyde exceeding the standard.

Of the unqualified 14 batches of indoor wooden doors, 12 batches were judged as seriously unqualified. The reason why they failed was that the formaldehyde emission exceeded the standard.

According to the inspectors, formaldehyde emission is an important environmental protection index of indoor wooden door product quality. From the results of supervision and spot check, the formaldehyde emission of individual indoor wooden doors has reached 3.6mg/L, which is more than twice the standard limit of1.5 mg/L.

Deng Min reminded that indoor wooden doors with plywood, particleboard, fiberboard and other man-made boards as the main raw materials are more prone to the risk of excessive formaldehyde. Relatively speaking, the risk of formaldehyde exceeding the standard of solid wood doors is lower.
