Embodiment 1
[0041] A high-quality antibacterial and insect-proof paper manufacturing process in this embodiment includes the same pulping process, modulation process, papermaking process and post-processing process as the existing papermaking process. The pulping process is divided into plant fiber raw material pulping and pulping. Two steps of bleaching, the preparation process is divided into three steps of pulping, beating, sizing and filling. The main improvement of the process in this embodiment lies in:
[0042] After the plant fiber raw material pulping step and before the bleaching step, component A was added, stirred at a stirring speed of 170 r / min at a temperature of 34°C for 7 minutes, and then left to stand for 30 minutes to proceed to the next step;
[0043] Add component B before the sizing step in the preparation process, stir at a stirring speed of 10r / min for 50 minutes at a temperature of 28°C and transfer to the next step;
[0044] The component A includes the followin...
Embodiment 2
[0060] A high-quality antibacterial and insect-proof paper manufacturing process in this embodiment includes the same pulping process, modulation process, papermaking process and post-processing process as the existing papermaking process. The pulping process is divided into plant fiber raw material pulping and pulping. Two steps of bleaching, the preparation process is divided into three steps of pulping, beating, sizing and filling. The main improvement of the process in this embodiment lies in:
[0061] Add component A after the plant fiber raw material pulping step and before the bleaching step, stir at a temperature of 36°C at a stirring speed of 180r / min for 9 minutes, then let stand for 34 minutes and transfer to the next step;
[0062] Add component B before the sizing step in the preparation process, stir for 70 minutes at a stirring speed of 14r / min at a temperature of 30°C and transfer to the next step;
[0063] The component A includes the following raw materials i...
Embodiment 3
[0079] A high-quality antibacterial and insect-proof paper manufacturing process in this embodiment includes the same pulping process, modulation process, papermaking process and post-processing process as the existing papermaking process. The pulping process is divided into plant fiber raw material pulping and pulping. Two steps of bleaching, the preparation process is divided into three steps of pulping, beating, sizing and filling. The main improvement of the process in this embodiment lies in:
[0080] Add component A after the plant fiber raw material pulping step and before the bleaching step, stir for 7-9 minutes at a stirring speed of 175 r / min at a temperature of 35 ° C, and then stand still for 32 minutes to transfer to the next step;
[0081] Add component B before the sizing step in the preparation process, and stir for 60 minutes at a stirring speed of 12r / min at a temperature of 29°C and transfer to the next step;
[0082] The component A includes the following r...
