Detailed Product Description: | Xingtai the crystal growing season sales the low vacuum microcrystalline panel Jiangsu low vacuum crystallite panel the vacuum box dehydration mechanism: the vacuum box dehydration mechanism, on the one hand, due to the up and down pressure of the sheet the errand of paper page compression and dehydration, on the other hand is due to air flow through the internal voids of the paper sheet, the fibers of water into the vacuum box. Under normal circumstances, the waterline before the vacuum box (Note, referred to as the wet tank is not wet vacuum box), the in several vacuum box, the dewatering are mainly due to the compression of the sheet up and down the pressure difference sheet dehydration; water line after the vacuum tank is referred to as the dry box, several vacuum suction tank, the dehydration of the paper sheet is mainly due to air flow through the internal voids of the paper sheet, the fibers adhering water into the vacuum box. Waterline means in the first vacuum box of the papermaking machine, due to the high moisture content in the wet paper sheet (in the general case, the degree of dryness of the wet paper sheet at 7% or less), the fibers are still suspended in water, its surface is flat surface, light reflection, the meniscus as a mirror: when further dehydrated, the fiber that is exposed liquid surface, light scattering, mirror disappears, the dividing line between these two is called "Watermark". Under normal circumstances, about 7% of the waterline when the wet paper sheet dryness, preferably waterline should be a flat or near flat, if the waterline appears when tongue traverse, said headbox jet The out of paper material is unstable. Moving in, there are differences in the sheet banner declared. Position emerging from the waterline, but also can determine the net dehydration the waterline appeared long ago dehydration is faster; contrary dehydration is slow. |
