10.3. During the production of the cigarette paper, should add certain quantity of CaCO_3, it can improve the whiteness and opacity, but will have bad effect to the tensile strength, so should control usage of the CaCO_3, in the meantime should meet the demand of the National Standard, the quantity of the CaCO_3 normally controls at about 30-40%, meanwhile can add small quantity of TiO_2, so as to improve the opacity.
3.在卷烟纸生产中,必须添加一定量的CaCO_3填料,可以提高纸张的白度,不透明度,但是其对抗张强度有负面影响,所以必须控制一定的量,同时又要满足国家标准的要求,CaCo_3的添加量一般控制在30-40%左右,同时可适当加少量的TiO_2,用以提高改善卷烟纸的不透明度。
