• 2022-01-28 Our product polyacrylamide is used in many sand washing factories

  We are specializedin supplyingflocculants for sand washing sewage treatment invarious regions. Recently, we have checked and compared ourpolyacrylamide with other polyacrylamidesample supplied bya distributor in Zhejiang, and found that the performance of their product with the molecular weight18 million is the same as our product with themolecular weight14 million. After being treated with polyacrylamide flocculant, the muddy water of sand factory can be recycled or discharg…

• 2025-08-22 Case 4: Indonesia - Corrugated Paper Mill

  ·Background and Challenges:·The mill produces high-strength corrugated paperusing 100% domestically produced OCC as raw material.·The pulpquality fluctuated significantly, and charge neutralization was difficult due to the low local water hardness. ·The goal was to increase tensile strength and compactstrength (CCT) while reducing steam consumption (i.e., improving drainability).·Solutions: ·A synthetic microparticle retention system combining nanosilica and CPAM was ad…

• 2025-08-20 Case 3: Thailand - Premium Coated White Paperboard Mill

  Background and Challenges:· Themill produces premium coated white paperboard using 100% recycled pulp (OCC + MOW) as the base layer and virgin chemical pulp as the top layer.· The main challenge was the high anionic trash content in the base pulp, which resulted in unstable performance of traditional single-component retention aids.· The retention rate of fillers (kaolin and calcium carbonate) was low (approximately 52%), resulting in cost waste and sedimentation problems.…
