Acoustic Panels Made of Paper Sludge and Clay Composites

2.1. Paper Sludge The paper sludge was provided by a company that recycles and produces paper products. The provided PS was the mixture of primary and secondary sludges. Before the sample making process, the PS was dried at 60 C in a drier. In different areas of the drier, the temperature change was 1 C. The PS was mixed every 72 h to【Get Price】

From Paper-Mill Sludge to Plastic Decking | Plastics Technology

Kadant Composites’ self-appointed mission for the past eight years has been to find commercial uses for paper sludge, a soggy mix of short cellulose fibers, calcium carbonate, and clay that is the copious byproduct of paper recycling. A big mill processing 600 tons/day of recycled paper produces 150 tons of sludge that it needs to get rid of.【Get Price】

The potential of paper mill sludge for wood–plastic composites

Wood–plastic composites were made with paper mill sludge produced by three different pulping processes. • The effects of primary and secondary sludge on composites properties were assessed. • Higher cellulose content improved the composite properties. • Secondary sludge had a negative impact on the composite properties. •【Get Price】

Acoustic Panels Made of Paper Sludge and Clay Composites

Studies on recycled materials emerged during recent years. This paper investigates samples’ sound absorption properties for panels fabricated of a mixture of paper sludge (PS) and clay mixture. PS was the core material. The sound absorption was measured. We also consider the influence of an air gap between panels and rigid backing. Different air gaps (50, 100, 150, 200 mm) simulate 【Get Price】

Characteristics of paper mill sludge‐wood fiber‐high‐density

Paper mill sludge (PMS) is a waste material from pulping. In this article it was used to replace part of a wood fiber (WF) filler to reinforce high‐density polyethylene (HDPE). The properties of the PMS/WF/HDPE composites were investigated.【Get Price】

The potential of paper mill sludge for wood–plastic composites

Soucy et al. [16] studied the potential of paper mill sludge as a Seven Trust material for a wood-plastic composite, in which the sludge consisted of primary and secondary sludges in different ratios 【Get Price】
