How to distinguish good desiccant?

Packaging to achieve the effect of moisture absorption, we should pay attention to the quality of the desiccant itself. How to buy a good desiccant? The following Xiaobian to share with you the purchase method:

The selection of raw materials, different products moisture-proof should choose the appropriate desiccant, desiccant types are many, common silica gel desiccant, calcium chloride desiccant, mineral/montmorillonite desiccant, molecular sieve desiccant, etc. Each desiccant moisture absorption rate is not the same, choose suitable for their own product characteristics of desiccant to achieve moisture-proof effect.

Here are a few things to note:

1. Appearance judgment: high-quality bag desiccant products have clean appearance, clear printing, moderate sealing width, no material clamping and full raw materials. Poor quality desiccant is rough workmanship, sealing width is different, some because the bag is too small, especially swollen.

2, packaging material judgment: good desiccant packaging material thickness uniform, no spots, smooth surface, high strength, unlike poor thickness uneven, rarely can see raw materials, hand kneading will fade, some fibers will fall off.

3, open to view the raw materials: high-quality desiccant is uniform size particles, direct touch with the hand will produce obvious heating, and inferior desiccant feel is not very obvious, impurities and particles more, different sizes.

4, moisture absorption rate test: if conditions permit, can weigh the original weight of desiccant, placed in a humid environment, natural moisture absorption for 48 hours, then weighing. A good quality desiccant should increase significantly and then dry at 105 degrees before weighing for three hours. If it is lower than the original weight, it proves that the desiccant does not conform to the nominal weight of the industry and is inferior desiccant products.

According to the above methods, you can choose good quality desiccant. I hope the sharing of Xiaobian will help you to learn more about desiccant. Welcome to pay attention to company dynamics.
