The formaldehyde concentration of palm mattress exceeds the standard mainly because the glue used contains a lot of formaldehyde, and there are three main solutions. First of all, the mattress should be exposed to the sun in a ventilated place, which can not only accelerate the volatilization of formaldehyde, but also release formaldehyde faster at high temperature. Secondly, put some activated carbon in the mattress. Activated carbon can absorb formaldehyde and other harmful substances in the mattress to the maximum extent, but it should be replaced regularly, otherwise it may cause secondary pollution. In addition, you can buy special in addition to formaldehyde agent and in addition to formaldehyde by chemical means, but you must consider whether the agent is harmful to the mattress.
