The quality of activated alumina desiccant is related to the effect of use. What ways should we judge it?

1. Appearance judgment. Activated alumina desiccant with high quality has neat shape, clear and distinguishable printing, moderate sealing width, no clips and good raw material plumpness. The poor quality desiccants are mostly rough workmanship, different sealing width, and some of them will be particularly bulging because the bags are too small.

2. Packaging material judgment: Good active alumina desiccant package is uniform in thickness, no spots, smooth in surface and high in strength. It will not be uneven in thickness like inferior one. Raw materials can be seen in very few cases. When kneaded by hand, the color will fall off and the fibers will fall off.

3. Look at the quality of raw materials: Activated alumina desiccant is made of uniform granules in size. Direct touch with hands will cause obvious fever, while inferior desiccant raw materials will not have obvious fever, and there are many impurities and different particle sizes.

Fourth, weighing discrimination. When conditions permit, the original weight of the active alumina desiccant can be weighed, placed in a humid environment, let it absorb moisture naturally for 48 hours, weigh again. The high-quality desiccant should be significantly increased, then dried at 105 degrees and weighed again after three hours. If it is lower than the original weight, it proves that the desiccant does not meet the industry's nominal weight. Low quality desiccant products.

The active alumina desiccant we purchased should be economical and practical, and judging whether it is good or bad should be based on understanding. I hope the above measures will be helpful to you.
