Filler Sludge Encapsulant

Product Specification

Feature

The cationic functional polymer forms bridging bonding between plant fiber and inorganic filler particles such as calcium carbonate and talc, firmly fix loose filler on the fiber network. It sharply reduces filler outflow along with white water, cuts the waste of mineral raw materials. High filler addition will normally damage paper tensile strength, ring crush strength and surface bonding performance. This agent builds a tough connecting structure between filler and fiber to compensate strength loss comprehensively, allowing paper mills to raise filler proportion reasonably for cost control. A large amount of suspended filler recovered from circulating white water can be reused directly in the pulp system after conditioning, decreasing the consumption of newly purchased light calcium carbonate and heavy calcium carbonate, bringing stable raw material cost advantages for long-term continuous production. Moderate cationic charge will not cause over-flocculation of the wet-end system, coordinate well with AKD sizing agent, surface sizing agent, conventional retention aids and dry strength additives, will not trigger abnormal foaming, sticky deposit or sizing failure. Eliminate the aggregation of free filler inside the pulp, avoid white dots, ash unevenness and basis weight fluctuation on finished paper, upgrade paper appearance quality and product grade steadily. Lower suspended solid concentration in circulating white water, reduce dirt accumulation on forming wire, press roll and pipeline, prolong the cleaning cycle of paper machine, meanwhile reduce flocculant dosage for terminal sewage treatment. Designed for neutral and alkaline papermaking process, no acidic ingredients, will not accelerate aging and corrosion of dryer cylinder, metal pipeline and forming fabric, protect paper machine spare parts. Liquid finished product can be directly connected to pulp pipeline for quantitative feeding via metering pump, no manual dissolution and stirring steps, reduce on-site labor operation difficulty and dosing error. Free filler will adsorb active components of sizing agent and weaken waterproof effect. After filler is fixed effectively, the consumption of sizing chemicals can be stabilized and reduced indirectly, balancing production cost further. Excellent adaptability for virgin wood pulp, mechanical pulp and recycled pulp, applicable to copy paper, offset printing paper, box board and liner board, flexible for production formula adjustment and trial verification.
