Roller surface dirty deposit is a common long-term trouble in continuous papermaking operation. Press rollers, drying rollers and calender rollers will gradually accumulate sticky glue, fine fiber fragments, filler dirt and aged sizing residue during long-term high-speed running. Accumulated dirt will form irregular sticky blocks on roller surface, which will transfer to wet paper web, forming sticky spots, indentations and transparent spots on finished paper. Serious roller dirt will scratch paper surface in real time, cause large-area surface damage, and force the workshop to stop production for manual wiping and chemical cleaning. Frequent shutdown cleaning lowers machine operation efficiency, increases water consumption, cleaning agent cost and labor cost. In addition, uneven roller dirt will cause uneven pressing force, lead to paper thickness deviation and loose local structure, further deteriorate batch quality stability. Traditional roller cleaning agents have strong corrosiveness, shorten roller rubber service life, and pollute circulating water system. Shandong Ludao Energy Technology Co., Ltd. provides integrated anti-deposit and cleaning solutions for papermaking rollers. It reduces adhesion force of colloid and impurities from the water system side, inhibits dirt deposition on roller surface, and decomposes residual old dirt mildly without corrosion. The technology prolongs roller cleaning cycle, cuts downtime frequency, protects roller surface integrity, ensures uniform pressing and calendering effect, and realizes long-term clean and efficient operation of paper machine rollers.
