초록

This study was made to investigate the effect of tensile strength(kg/$\textrm{cm}^2$), opacity (%), porosity(cc/min) of the paper manufaturing with the freeness properties of NBKP and the calcium carbonate having the different physical and chemical properties.As the results, the opacity and porosity of the freeness of NBKP, obtained good strength properties from the freeness 65$^{\circ}$SR and the tensile strength from the freeness 85$^{\circ}$SR. The strength properties of paper manufacturing loaded with calcium carbonate appears to be related to the effect of the freeness, and it was obtained the good results at opacity 83.8% in the freeness 85$^{\circ}$SR, tensile strength 3.8kg/$m^2$ porosity 87cc/min in the freeness 65$^{\circ}$SR.Addition of 50%, 55% 60%, CaCo3 was found to increase slightly the strength properties of paper.
