The Analysis of the Plywood Formaldehyde-Emission Loose

There is the theology of the plywood formaldehyde-emission which is similar to the solid and the liquid. The mature theory of rheological is applied to study on the mechanism of the plywood formaldehyde-emission in this paper, and the loose models of the plywood formaldehyde emission are created. The formularies F_M = F₀e^-0.1429t and P = P₀/k(1-e^-0.1429t) can be received and used to describe the influence of the placed time of sawed test piece to the plywood formaldehyde-emission. The deviation between the theory value and the test value is 0.52 mg/L.
