MFC-PCC Hybrid가 첨가된 수초지의 물성 평가

The MFC-PCC hybrid was prepared by physical pre-treatment of MFC and PCC. physical pre-treatment refers to the state where MFC and PCC were homogenized. In this study, it was called MFC-PCC Hybrid. When the MFC-PCC hybrid was applied, not only the tensile strength and ash content of handsheets were high, but also the pore size decreased. Also, as the homogenization rate of MFC and PCC increased, tensile index and pore size of handsheets were decreased and then increased again. As a result of investigation the coagulation behavior of the MFC-PCC hybrid, the zeta potential decreased with increasing homogenization rate, and it was found that the MFC and PCC behaved in the order of coagulation-dispersion-coagulation. These results showed that electrostatic bonding between two factors was not always achieved through homogenization of MFC and PCC, and it was expected that the cohesion of several cases may affect the properties of handsheets. In this regard, future research will attempt to prepare the MFC-PCC hybrid by controlling the time.
