Calcium chloride desiccant generates liquid water (calcium chloride solution) when it absorbs moisture in the air. It is prone to leakage when liquid water is in use. If calcium chloride solution leaks out at this time, it will be placed. The cargo of the calcium chloride desiccant is contaminated. The calcium chloride is absorbed by the air and stored in the state of liquid water for 2-3 days to form a gelatinous calcium chloride desiccant (calcium chloride hexahydrate) by internal decomposition reaction. )Lock water. Chunwang's most important focus in the production process is the leakage protection of calcium chloride after it becomes water. So, how should we choose effective calcium chloride desiccant packaging paper?
We should choose a good permeability paper as the packaging material of calcium chloride desiccant, so as to ensure that the calcium chloride desiccant can be in contact with air, effectively preventing moisture and dehumidification, but if it is ordinary air-permeable wrapping paper, it can not effectively prevent chlorine. Calcium water leakage, such as non-woven fabrics, Aihua paper, OPP film, these breathable papers can not be used in calcium chloride, they have no leak-proof ability, we have to choose some more high-grade wrapping paper Effectively prevent leakage.
At present, the calcium chloride desiccant wrapping paper mainly used by Chunwang is DuPont paper, which can effectively prevent liquid leakage through a layer of gas permeable membrane formed by DuPont paper.
