GB 10455-89 Silica Gel Desiccant for Packing
Silica gel desiccant is a highly active adsorption material, which is usually made of silica gel bead or sheet. Its most notable feature is the adsorption of moisture and dehumidification. Because of its high moisture adsorption capacity, it is widely used in building materials, pharmaceuticals and foods. GB 10455-89 is China’s national standard for the desiccant for packing. It is applicable to the inert desiccant for various products packed in closed packaging containers.
Silica gel desiccant for packing can ensure that the product sealed in the packaging container does not absorb any moisture from the outside, and does not leak out of the container to ensure the quality of the product. The desiccant for packing shall not be contaminated by foreign matter such as heavy metal ions and can be used without any harm to the human environment. The desiccant also has the characteristics of easy to use, friendly to the environment and non-toxic.
The requirements of GB 10455-89 desiccant for packaging are mainly divided into three aspects:
(1) Technical indicators
The technical indicators of GB 10455-89 silica gel desiccant mainly include desiccant weight, applicable temperature and humidity, adsorption capacity and regeneration temperature.
(2) Assay
GB 10455-89 silica gel desiccant includes monosilicic acid, heavy metal ions, oil and silt, etc. The maximum of these items shall comply with the specified requirements.
(3) Shelf life
The unopened desiccant of GB 10455-89 standard can be stored for two years when it is stored in a dry, ventilated environment.
In conclusion, the desiccant for packing of GB 10455-89 standard has good performance and quality, which can ensure the moisture proof of packed products. In order to better ensure the quality and protect the environment, relevant departments shall formulate corresponding regulations and strictly enforce them. Managers must pay attention to the implementation of laws and regulations, do a good job in product selection and use, and avoid violating the relevant provisions.
