When we buy desiccant, we must first communicate with the manufacturer to determine what the desiccant is used for, and whether it is for decoration or for anti-mold and moisture-proof. If it is only for decoration, you can choose a broken particle desiccant of lower quality. It will be relatively affordable. If you are afraid that the product will deteriorate due to moisture, then you should explain to the manufacturer that you want a desiccant with no damage.
The unit price of desiccant should not be considered blindly. Everyone knows that you get what you pay for. The price of desiccant is generally relatively stable. If it is recycled material or glass beads, the price of desiccant is generally about 0.005 yuan/g, if it is half broken beads The price of desiccant is generally about 0.007-0.008 yuan/g, and the price of A-grade desiccant is generally 0.01 yuan/g.
The silica gel food desiccant mainly checks its water absorption performance. The desiccant absorbs the moisture of the air and produces a chemical reaction by itself. Usually the desiccant breaks when it absorbs air moisture and generates high temperature. When we buy the desiccant You can disassemble the desiccant first, and then drop a few drops of water into the desiccant to observe its chemical reaction. If a good-quality desiccant can absorb moisture instantly, a good-quality desiccant will feel hot, because now Many manufacturers take tricks and treat glass beads or expired desiccant raw materials as top desiccants to fool customers. If the glass beads or deteriorated desiccant cannot absorb moisture and the surface does not have any temperature.
