How to determine the dosage and timing of using paper-making deodorant
In order to ensure better production of paper and prevent the introduction of bacteria and erosion, it is necessary to incorporate a paper-making deodorizer into the process. The use of paper-making deodorizers is also quite technical; both the dosage and timing need to be precisely controlled to achieve the desired effect. Today, our editor from Qingdao Xiangze Chemical will provide a detailed explanation on how to grasp the dosage and timing of using paper-making deodorizers:
Papermaking deodorant is an industrial agent that requires a certain onset time, which varies depending on the type. Chlorine is a fast-acting agent, while isothiazolinone is a long-acting agent. Its onset time is approximately 1 to 2 hours (also dependent on the dosage). Therefore, it is crucial to determine the appropriate location, time, and method of dosing to maximize the effectiveness of papermaking deodorant.
Years of experience have shown that the optimal addition point for paper-making deodorant is in the stock preparation pool, slurry storage pool, or mixed stock pool (add all the auxiliaries used before adding the preservative). During continuous pulping, using a shock dosing method can extend the residence time of the paper-making deodorant in the slurry and ensure more uniform mixing with the slurry. If pulping is intermittent, the deodorant should be added in one go when half of the pool is filled with slurry in the slurry storage pool.
Regarding the dosage of paper-making deodorant, each paper mill should adopt a sludge treatment measure that prioritizes prevention and combines prevention with control. They should actively manage the microbial content of raw materials and water sources, and regularly monitor the sludge or microbial conditions in the paper-making system during production. At the same time, the pH value and immune performance of the deodorant should be determined based on factors such as season and environment. Dosage: Different dosages should be tested on the slurry during initial use to ensure that after dosing, the microbial content of the slurry is controlled between 10~10. An accurate dosage should be determined when the microbial content in the slurry is ≤10, indicating that paper defects caused by microbial growth will not occur. (In subsequent production processes, the microbial content should be regularly monitored, and the dosage of paper-making deodorant should be adjusted based on the content. It should not be too much or too little, just the right amount.) At the same time, to avoid intermittent high-dose use of the system on product immunity, the highest activity of the deodorant should be maintained.
The above is an explanation of the dosage and timing of using paper-making deodorizers.
