The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
As shown in Figure 1, coated white cardboard described in the utility model is composited by surface layer, sandwich layer, bottom, and facial tissue layer 1, ground paper layer 2, core paper layer 3 can have two, three etc. as core paper layer 3 of the present utility model.
1, slurrying
1. facial tissue layer: the pulpboard of facial tissue layer is pulled an oar (as for then directly pulling an oar from slurrying) after through the hydrabrusher size degradation, prepares burden then, and the slurry dexter feeder of making is manufactured paper with pulp.
2. ground paper layer: the pulpboard of ground paper layer is pulled an oar (as for then directly pulling an oar from slurrying) after through the hydrabrusher size degradation, prepares burden then, and the slurry dexter feeder of making is manufactured paper with pulp.
2, the adding that has the expansion particulate of the function of thickening
It can be in two-layer the beater floor of any one deck or the stream portion of sending of paper machine add.The selectable inflatable particulate model of present embodiment is: EXPANCEL
820SL40 and 820SL80 and 820SLU40, granularity is: 10 μ m-24 μ m, expansion particulate addition is counted by the over dry of paper gross weight: 0.3%～2.5%.Producing used expansion particulate is produced by AKZO NOBEL.
3, copy paper
Facial tissue layer slurry, the ground paper layer made are starched veil and the spacer screen of delivering to the paper machine respectively and are manufactured paper with pulp, then through squeezing, dry and coating, and last press polish ornamenting, obtain hanging down high-grade coated white cardboard quantitative, high thickness.
4, white-water system
In the paper machine making process, with the plain boiled water of facial tissue layer, ground paper layer separately, establish two special faces, ground paper layer back flow water pump (pond), when the starching of paper machine dilute, and slurrying workshop section pulpboard size degradation and transferring when dense, with the separately use of each layer plain boiled water.
