Tip: Chengdu Shengli Technology Co., Ltd. also develops and produces special molecular sieves for users.
〖Packing〗·30kg sealed steel drum ·140kg sealed steel drum ·500kg container bag
〖Storage〗It should be stored in a dry room at 2～50℃ and relative humidity ≤90%RH, and avoid water, acid and alkali.
〖Note〗 After the molecular sieve absorbs moisture, it can be used after regeneration treatment, and its effect remains unchanged.
