Inorganic scale deposition in circulating white water is a persistent hidden hazard that plagues long-term continuous operation of papermaking water systems. White water contains dissolved calcium, magnesium, silica and residual mineral additives, which will precipitate and form hard crystalline scale under temperature rise, pH fluctuation and microbial metabolism. Adhered scale accumulates on pipeline inner walls, heat exchangers, shower pipes and forming mesh surfaces, narrowing water flow channels, blocking spray nozzles and reducing heat exchange efficiency. Severe scale deposition causes uneven water spray, unbalanced pulp dilution, periodic paper thin spots and mesh fouling acceleration. Traditional scale inhibitors only chelate metal ions temporarily and fail under high-temperature and high-hardness water conditions, leading to rapid scale reformation. Manual chemical cleaning causes pipeline corrosion, downtime loss and circulating water secondary pollution. Shandong Ludao Energy Technology Co., Ltd. provides systematic white water scale suppression solutions. By inhibiting crystal nucleation and growth of inorganic ions, dispersing micro-scale particles and modifying wall adhesion characteristics, we prevent hard scale formation and existing scale re-crystallization. The solution keeps pipelines and equipment clean long-term, stabilizes white water flow and temperature control, eliminates scale-induced periodic paper defects, reduces shutdown cleaning frequency, and realizes low-maintenance continuous production.
