Abstract

The work aims to save plant fiber raw materials, and use ceramic fiber as filler fiber to evaluate the practicability of waste paper pulp/ceramic fiber for papermaking. After treating the surface of ceramic fiber with KH-550 silane coupling agent, the untreated and treated ceramic fibers were added in the handsheets at a certain proportion. The properties of the handsheets, including tightness, tear index, ring crush compression resistance, folding resistance and tensile strength were compared. And the micro morphology of the handsheets was observed. The results showed that the ceramic fibers were interlaced and dispersed among the paper fibers. When the mass fraction was less than 20%, the tear index, ring crush compression resistance, and tensile strength of the handsheets treated with KH-550 silane coupling agent decreased with the increase of the fiber content; when the mass fraction was more than 20%, the above properties all increased with the increase of fiber content. But the folding resistance of handsheets decreased significantly with the increase of treated ceramic fiber. The ring crush compression resistance of the handsheets was significantly improved. When the mass fraction of ceramic fiber was 40%, the ring crush compression resistance was 3.81 kN/m, which was 2.06 times that of the waste paper fiber handsheets. Adding ceramic fiber to 40% by mass not only saves raw materials of plant, but also improves the ring pressure compression resistance of handsheets. It can be used for paper materials with high ring crush compression.
