preservatives in
paper towels
The selection of fungicides and preservatives should be determined according to factors such as production conditions, the nature of the slurry, and the PH value. Toilet paper manufacturers recommend that antibacterial and preservatives with a broad bactericidal spectrum should be used as much as possible; for long-term use, two or more antibacterial preservatives should be used alternately to avoid microbial resistance; for example, when adding paper and cardboard that contact food in packaging , its toxicity and the maximum allowable usage should be considered.
Pay attention to the influence of pH value. Generally, acid bactericidal preservatives should be used for alkalophilic bacteria, and alkaline bactericidal preservatives should be used for acidophilic bacteria. It is inevitable that
paper towels must be preservatives, but it is necessary to choose preservatives with guaranteed quality. The characteristics of preservatives: efficient, fast, broad-spectrum bactericidal and bacteriostatic ability, so that bacteria are killed in a short time or their cells lose their ability to grow and reproduce.
It should have low toxicity, easy decomposition and certain solubility. After use, it will decompose on its own under certain conditions, causing no or little pollution to the environment and no harm to product users. No irritating odor, no serious pollution to the environment or no adverse effect on the operator; it has a long-term effect on microorganisms, and bacteria will not develop resistance in a short time and lose their effect on it.
It is not only wood that can be used to make paper, but also bamboo, grass, etc., these materials are made into pulp, that is, wood pulp, bamboo pulp, grass pulp, etc. Pure wood pulp means that only wood pulp is used, and other pulps such as bamboo pulp and straw pulp are not used, but it is not excluded that it contains recycled wood pulp. Corresponding to virgin pulp, it is recycled pulp, which is recycled pulp, which is made of recycled waste paper that meets the standards.
The recycled waste paper has to go through processes such as shredding, deinking, bleaching, etc. Among them, there are more fibers cut, and the paper produced will have more paper powder. At the same time, the amount of bleaching agent is also large, and sometimes the whiteness cannot be achieved. , manufacturers may also use fluorescent whitening agents. National standards allow the use of recycled pulp to make toilet paper. However, recycled pulp cannot be used in the manufacture of tissue paper, and virgin pulp must be used, such as virgin wood pulp, bamboo pulp, and straw pulp.
