the processing of die forming fiberboard and honeycomb core base material can be divided into for two steps: the die forming fiberboard, because the viscose fibre in fibrofelt is thermoplastic fibre, the fiberboard forming technology is preheating → mold pressing, in addition, be shaped for the ease of the honeycomb core bending, during the fiberboard die forming, have onboard radially or mold pressing clause that broadwise is parallel to each other, clause place fiberboard thickness is less, and bending rigidity is less, and the clause spacing equals the honeycomb core length of side, the processing of honeycomb core base material, most honeycomb core is bonding according to certain rules by number lamellar material, stretching forms, here the processing technology of honeycomb core base material is adhesive to be coated on according to certain rule form adhesive tape on fiberboard, fiberboard is mutually bonding from level to level, mode is to stagger in the adhesive tape position of adjacent two layers fiberboard, be that last layer fiberboard adhesive tape position is just in time in the centre of two adhesive tape of lower one deck adjacent fiber plate, the multi-layer fiber plate that is bonded together by this way need flatten, oven dry a period of time, so that the adhesive that is coated between fiberboard fully solidifies, the final honeycomb core base material that forms.
The processing technology of honeycomb core is that honeycomb core base material is cut into the honeycomb core base material bar that a rule has the height that requires, cutting mode is perpendicular to the fiberboard plane, perpendicular to the adhesive tape on fiberboard, then, preheating honeycomb core base material bar, stretch in its section segmentation, honeycomb core base material bar is launched, namely form hexagon textile waste honeycomb core.
The present invention has following outstanding effect:
(1) can utilize on a large scale textile waste, because the honeycomb core purposes is wide, consumption is large;
(2) can utilize on a large scale the hard textile waste that length is short, kind assorted, color is many, quality discrepancy is large, because honeycomb core does not have too high request to outward appearance, different purposes quality requirements are widely different;
(3) need not the different fibers in textile waste are distinguished, this is a great problem during the hard textile waste utilizes;
(4) need not the textile waste decolouring, this is another hang-up during the hard textile waste utilizes;
(5) can improve the added value of textile waste.
