The odd ply that used microwave technology accumulates material product line to already many line is in moving production. This product line is increasing the intensity is very only low report magnetic field all round hot cell, to personnel herein walk to was not affected; Microwave heats beforehand the system has very high energy to russia hardwood flooring demand type change rate, raised the manufacturing rate of successive press product line greatly. Make the same score continuously press hot press to see the graph is shown 9 times.
Graph 10 be those who contain microwave to add shrinkage fitting buy beforehand is successive smooth press hot press. Successive press grows degree of 38 ～ 60 M; Suppress product width 4 ′ , lowest price composite deck tiles 6 ′ or 8 ′ ; ～ of 1 500 of width of hot pressing plate 2 650 Mm. In give makings end to have two drive roller. Hot pressing speed 10 ～ 200 Mm/s. Successive press entrance designs plywood compact, distance is short; The final thermal treatment zone of press region asks without high heat energy (can shut heat source in order to cool element board base) .
The hot pressing requirement to veneer moisture content, veneer moisture content 15% , glue of colophony of use Niao aldehyde reachs solidify agent, solidify factor (press factor) 40 S/mm; outdoor waterproof panels Veneer moisture content 6% , glue of colophony of use Niao aldehyde reachs solidify agent, solidify factor 30 S/mm, productivity rises 30% ; Accumulate material to produce to veneer layer, must use gum of liquid phenolic aldehyde (without solidify agent) , its veneer moisture content asks to be 6 % .
