Problems solved by technology

With the advancement of society and the improvement of people's lives, various household papers are flooding people's lives. Ordinary household papers do not have antibacterial functions. Paper contaminated by bacteria is not only prone to mildew but also It affects the quality of its use, and it can also become a medium for the spread of many germs. Therefore, an antibacterial paper with antibacterial function came into being, but this kind of antibacterial paper is mostly coated or sprayed on its surface. Its antibacterial effect will change in the further processing process or with the storage time and storage temperature, so that it will become invalid; some manufacturers try to add antibacterial agents to the slurry to produce antibacterial paper, but adding it to the slurry The antibacterial agent is easy to be lost with the white water when the paper is copied on the Internet. The antibacterial dose added is very large, but the antibacterial dose retained in the paper is very small, which not only increases the cost, but also fails to achieve a good antibacterial effect.

example 1

[0022] No retention aids are added, antibacterial agents and softeners are added to the pulping tank, and the pulp concentration in the refining tank during the pulping process is 4.5%:

[0023] 1. According to the volume of slurry mixing tank is 30m 3 , the concentration of the pulp after dilution is 3.3%, and the absolute dry pulp volume of each pool of pulp is calculated = 30 * 3.3% = 1.0 tons;

[0024] 2. Weigh 6kg of paper-based antibacterial additives (mainly composed of long-chain polyquaternium and isothiazolinone) produced by Hangzhou Xi’anda Antibacterial Technology Research Institute Co., Ltd. according to 0.6% dry pulp, add 80 times of water Dilute and stir evenly for later use;

[0025] 3. Weigh 3.6 kg of "Jinfang" softener produced by Unilever Co., Ltd. according to 0.3% of dry pulp, add 50 times of water, dilute and stir evenly for later use;

[0026] 4. Slowly add the solution in steps 2 and 3 into the pulp mixing tank filled with pulp, and after the pulp is ...

example 2

[0028] Add the retention aid, antibacterial agent and softener to the pulp mixing tank successively, and the pulp concentration in the pulping tank in the pulping process is 9%:

[0029] 1. According to the volume of the mixing tank is 30m 3 , the concentration of the pulp after dilution is 3.3%, and the absolute dry pulp volume of each pool of pulp is calculated = 30 * 3.3% = 1.0 tons;

[0030] 2. Weigh 6kg of paper-based antibacterial additives (mainly composed of long-chain polyquaternium and isothiazolinone) produced by Hangzhou Xianda Antibacterial Technology Research Institute Co., Ltd. according to 0.6% dry pulp, add 80 times of water Dilute and stir evenly for later use;

[0031] 3. Weigh 3.6 kg of "Jinfang" softener produced by Unilever Co., Ltd. according to 0.3% of absolute dry pulp, add 50 times of water, dilute and stir evenly for later use;

[0032] 4. Weigh 6kg of retention aid powdered polyacrylamide according to 0.5% of absolute dry pulp, add 100 times of cl...

example 3

[0035] In the online papermaking process, the retention aid is continuously added to the white water tank, and the antibacterial agent and softener are continuously added to the high level tank. The pulp concentration in the refining tank in the pulping process is 9%:

[0036] 1. According to the speed of the paper machine (160m / mim) and the weight of the paper produced (16g / m 2 ) and width (1.9m) and crepe rate (70%), it can be calculated that the paper output in 8 hours = 160m / min × 16g / m 2 ×1.9m×60 minutes×8×0.7÷1000=1634 kg base paper;

[0037] 2. Take by weighing 6.54 kilograms of Lobenqing (main component is benzalkonium chloride) and 6.54 kilograms of glutaraldehyde produced by Canada Loster Co., Ltd. by 0.4% of dry paper weight, add 100 times of clear water to dilute and stir evenly, Put it in the metering tank for use;

[0038] 3. Weigh 5 kg of "Langqi" softener produced by Procter & Gamble Company according to 0.3% of the weight of dry paper, add 100 times of water...
