Abstract: To improve the way of efficient recycling of waste Tetra Pak package, save wood materials and develope new packaging materials, this article studied on the optimum hot-pressing process and surface decoration of waste Tetra Pak/sawdust composite board. Using the orthogonal experimental method, we studied the effect of that four factors, such as resin content, hot-pressing temperature, hot-pressing time and Tetra Pak/sawdust mass ratio, on MOR, MOE, TS for 2h of waste Tetra Pak/sawdust composite board. And according to the measurement and analysis of these three test indicators of the board, we obtained the optimum hot-pressing process of waste Tetra Pak/sawdust composite board. The results showed the optimization of process parameters for the board was that: resin content for 14%, hot-pressing temperature for 150°C, hot-pressing time for 420s and Tetra Pak/sawdust mass ratio for 4:6 were suitable to product this board. At this point, the maximum MOR of the board was up to 23.1MPa, the maximum MOE of the board was up to 2917MPa, the minimum TS for 2h of the board was down to 6.1%. In the processing of PVC surface decoration, by using comparison tests, the results figured out that hot-pressing temperature for 50°C-60°C, hot-pressing time for 10s-20s, hot-pressing pressure beyond 0.02MPa were good for PVC to decorate this kind of board. The formaldehyde emission of this veneer composite board was 0.3mg/L, the surface abrasion resistance of it could reach 900r, besides, its performance of surface pollution resistance has reached the national standard.

Abstract: Under certain conditions, a test about the crackle-simulated coating technology of rice-straw board after sanding its surface, which aims to determinate several indexes include the glossiness of the coating surface, the hardness and adhesion of the film, the ability to resist of denaturing, and the feel of the surface, etc. The result shows that: the technology of rice-straw board crackle-simulated coating is available to the medium density fiberboard furniture. Though the indexes of the hardness and adhesion of the film are slightly low, they are all up to the standard of the nation and the enterprise. Moreover, we have also analyzed the decorating effect of the crackle-simulated coating of the surface, the economic cost, the environmental friendliness and other elements, in order to provide a reference frame to the special coating which is conducted on the furniture surfaces.
