Application Principle:
1. Physical adsorption: Molecular sieve powder have a large specific surface area and microporous structure, and there are a large number of molecular gravitational fields inside. During the use of electronic sealant, if moisture in the environment enters the glue, it will affect the performance of electronic components. The white molecular sieve powder can pre-absorb the moisture in the sealant, and can also continuously absorb the moisture entering during use to keep the environment inside the glue dry, and prevent short circuits and corrosion of electronic components due to moisture.
2. Aperture screening effect: The pore size of the activated molecular sieve powder is uniform and comparable to the size of the adsorbed molecules, which can play a role in screening molecules. Molecules smaller than its pore size, such as water molecules and carbon dioxide molecules, can enter the pores and be adsorbed; while molecules larger than its pore size are blocked outside the pores, thereby achieving selective adsorption of molecules of different sizes, effectively preventing the influence of impurities on electronic components, making the performance of the glue more stable and pure, and ensuring the reliability and durability of electronic sealant.
3. Polar adsorption characteristics: The surface of the activated zeolite powder has a certain polarity and has a strong adsorption capacity for certain polar molecules. Some polar impurities in the electronic sealant, such as organic matter containing functional groups such as hydroxyl and carboxyl, will be preferentially adsorbed by the it, thereby improving the purity and performance of the electronic sealant.
4. Improving stability
It can enhance the physical and chemical stability of the electronic sealant. Under different temperature and humidity conditions, it maintains the performance of the sealant, ensures the reliability and durability of the electronic sealant, and helps to extend the service life of electronic equipment.
