        摘要：Defibering processes of 3 plantation building use species used for manufacturing medium density fiberboard(MDF) were investigated and appropriate refining plate pattern was determined. Experimental conditions were as follows: 1)species were Chinese fir(Cunninghamia lanceolata),loblolly pine(Pinus teada)and slash pine(Pinus elliottii); 2)3 refining plate patterns were classified as mediumfine,medium and coarse; 3)chips were steamed under fixed pressure of 0.40.65MPa for 3,6,9 and 12 min respectively; 4)refining plate gap was adjusted to about 0.1mm.Experiment results showed: mediumlong fibers(retained on 32115 mesh) content was 50%70%,but medium plate pattern produced better fiber, cooking time had no significant effect on fiber quality and internal bond so that 3 min was enough for cooking.

        摘要：Based on experiment of poplar veneers bonded with PVAc in electric field,relationship between electric field action time and shearing strength between the veneers was preliminarily explored. Experiment results showed that the shearing strength was significantly affected by the time. The strength behaved the best when veneer moisture content was 12%, and 185 g/m\+2 of PVAc(content 17%,viscosity 6.0 Pas at 20 )was spread as adhesive under the following condition:room temperature (1724 ),0.450.85 MPa of pressure for 10 h, 30V of electric potential difference among pole plates initiated after 14 h pressing.\=

        摘要：Hygroscopicity of rubbrwood plywood treated with 6 kinds of flameretardants was investigated in this paper. Hygroscopic rate of plywood, hygroscopic rate of flame retardants, hygroscopic rate of plywood with 15% (ARC) were compared and estimated. The results showed that hygroscopicity of common phosphornitrogen was remarkably higher than that of WFR while hygroscopicity of all treated samples was higher than that of untreated samples.\=

        摘要：Contradiction between energy consumption and energy shortage has been intensifying in wood processing industry.But energy selfsufficiency technologies in certain foreign wood processing industries were developed and proved affective.To improve awareness of saving energy of domestic wood processing industries,the author analyzed cost/effectiveness relation between use of processing residues to produce energy and conventional energy consumption in wood processing industries,it indicated that it would be possible in theory to make wood processing industries selfsufficient in energy supply.
