Embodiment Construction
[0006] The present invention will be further described below in conjunction with embodiment.
[0007] A method for producing suede ultra-sensitive paper, which includes basic steps such as base paper production, double-sided coating processing, and roll sorting:
[0008] (1) Production of base paper: The production of suede super-sensitive paper first ensures the internal bonding strength, surface strength and smoothness of the base paper. Made of 100% wood pulp, including 40% softwood pulp, 60% hardwood pulp, beating degree 40-45°SR, pulp sizing concentration 0.5-1.0%, base paper basis weight 80-200g / m 2 , surface strength ≥ grade 12, surface absorption 20-30g / m 2 , the paper smoothness ≥ 30S;
[0009] (2) Double-sided coating processing: double-sided coating processing of the base paper to obtain suede super-sensitive paper, double-sided coating processing adopts roller feeding, air knife one-time coating molding, and the finished product is double-sided coating Paper, on...
