Press felt is a key core equipment for paper dehydration and forming, and its cleaning cycle directly determines continuous production efficiency and paper quality stability. During long-term high-speed operation, papermaking felt is easily blocked by fine fibers, filler particles, sticky colloids and residual chemical auxiliaries. Accumulated dirt blocks the felt drainage pores, resulting in reduced dehydration capacity, uneven water filtration and poor pressure uniformity. Blocked felt will cause paper surface water spots, thickness deviation, fine wrinkles and fuzzy texture defects, and seriously restrict the improvement of paper machine speed. Frequent shutdown cleaning and replacement of felt increases enterprise labor cost, material consumption and production downtime loss, while incomplete cleaning leads to rapid secondary fouling and short service life. Traditional felt cleaning agents are highly corrosive, easy to damage felt fiber structure, shorten equipment service life and pollute circulating water system. Shandong Ludao Energy Technology Co., Ltd. launches environmentally friendly felt anti-fouling and cleaning optimization solutions. By decomposing sticky dirt, removing micro-blockages and improving felt surface anti-adhesion performance, we effectively delay felt fouling speed and greatly extend the full-load cleaning cycle and service life. The solution is mild and non-corrosive, protects felt structural integrity, stabilizes press dehydration efficiency and paper forming quality, reduces shutdown maintenance frequency, and realizes long-term stable and efficient continuous production of paper machines.
