Production technology of high-strength corrugating base paper

[0024] Step 1: Pulping:

[0025] Domestic waste paper, including waste books and waste office paper, is pulped, screened, concentrated, and medium-consistency refined to obtain domestic waste paper pulp;

[0026] The second step: base paper processing:

[0027] The pulp obtained in the first step is formed, squeezed and dried to obtain base paper;

[0028] The third step: the preparation of sizing agent:

[0029] 10m with stirring 3 Inject 5.5 tons of water into the dissolving container, add 1 ton of starch into the dissolving container, add 2kg of ammonium persulfate after fully stirring, and send it into the glue tank with a pump. Start the heating device, intelligently control heating and heat preservation parameters: heat to temperature T1, T1=65°C, heat for 20 minutes, then keep warm at this temperature for 10 minutes, continue heating, heat to temperature T2, T2=95°C, heat for 15 minutes, then Keep warm at this temperature for 30 minutes. Heating during cooking, and th
