The effect of recycling white water quality on paper making 1. For making high-grade paper, the pulp, which is pulp workshop sent to the paper workshop, produce white water, because of the residual chlorine of the white water is high, it affects the paper machine color matching, sizing and so on, generally the white water will directly reuse to the paper workshop, and the water can be recycled to the pulp workshop for reusing. 2. Reuse white water usually contains small fibers, fillers, sizing material and other additives, when the suspended solids is high, will increase the ash content of finished paper, thus affect the paper strength. 3. After repeated recycling of reuse white water, microorganisms in the water multiply in large quantities, easy to cause pulp system appears rotted pulp mass, in the pulp chest and pipe wall will easy to form fog, microorganisms fall off and mix into the pulp, resulting in paper holes and paper machine broken. 4. Due to the use of fillers and o

All of us use paper every day. Yet, few realize all of the steps necessary to change plant material to this common, every day product. The fact that mankind ever stumbled upon this process is shear genius as the paper making process follows three steps: preparation of the fibers, sheet formation, and drying. Paper pulping process During the first step of the paper making process, the material used to make the paper is converted to pulp, which is a concentrated mixture of fibers that are suspended in liquid. Generally, the fibers are those found naturally in softwood trees, hardwood trees, or other plants. The fibers can also come from recycled paper, such as from newsprint, old corrugated boxes, and mixed paper. The paper pulping process consist of paper pulping, pulp cleaning, pulp screening or pulp refining Paper Making Process The next step is sheet formation. At this stage in the process, the pulp mixture is diluted some more with water. This is then strained throug

The high-consistency cleaner HCC reliably removes heavy ingredients from pulp suspensions at consistencies up to 6%. It thus protects downstream machines against wear. Thanks to a geometrically optimized high-turbulence intake head, the high-consistency cleaner HCC allows extremely effective removal of particles such as sand, glass slivers, staples and paper clips. There is hardly any wear even in extreme applications thanks to partial and/or complete ceramic lining. The rotorless design allows minimal maintenance outlay and a high level of operational reliability. In addition, the optimized trap design minimizes fiber loss through backwashing.
