The mathematical model for the formaldehyde emission from wood-based board in room

A mathematical model which describes the influence of various parameters on formaldehyde concentration in the atmosphere of a room containing wood-based boards was developed. The physical meanings and measuring methods of the parameters of the model are also discussed. Based on this model, two indices for commenting the formaldehyde emission process of wood-based boards are proposed, and inequality estimation for the formaldehyde content of wood-based boards at any moment and a time estimation which shows when the room satisfies the environment quality standard are also given.
