15mm厚中密度纤维板不同装饰后耐老化性能研究

Study of Durability about 15mm MDF Decorated by Different Material

研究了加速老化试验对经不同装饰后的脲醛胶中纤板物理力学性能的影响。结果表明,未经装饰的中纤板经加速老化处理后力学强度降低较快,吸水厚度膨胀率明显增大。选用的4种装饰中纤板中,三聚氰胺板的力学性能降低最大,油漆板耐久性能最好。

This article studies the impact of the accelerated physical and mechanical properties. The result indicates, after aging test to UF MDF decorated ,by different material about the accelerated aging, mechanical strength of MDF without any decorative decreased rapidly, the rate of absorbing water thickness expansion increases obviously, In the four kinds of decorative MDF, mechanical properties of MF MDF reduces quickly, the durabilitv of painting MDF is the best.
