1.Used as adsorbent, moistureproof agent and catalyst carrier

2.As gas chromatography reagent, thin layer chromatography reagent and catalyst, also used for gas drying, gas absorption, liquid dehydration, etc

3.Used for moisture proof, rust proof, gas dehydration, purification and catalyst carrier, can also absorb harmful elements in water

4.Used as desiccant and catalyst

5.Used as catalyst carrier and catalyst

6.It is used as a humidity indicator to show the desiccant humidity saturation, the relative humidity of packaging and space medium in precision instruments and meters

7.Suitable for chemical fertilizer, steel, natural gas and other industries oxygen production, nitrogen production and natural gas dehumidification process as dehumidifier, also used in military, ammunition and so on

8.It is a good reinforcing agent for rubber, and its reinforcing property is second only to carbon black. It is also used as lubricant and insulating material

9.It is mainly used for moisture absorption and rust prevention of instruments, instruments and equipment under closed conditions. At the same time, it can directly indicate the relative humidity of the environment through the transition of its color from blue to red after moisture absorption. It can also be used in conjunction with ordinary desiccant to indicate the degree of moisture absorption of desiccant and to judge the relative humidity of the environment.

10.Used as catalyst carrier, coating binder, pulp treatment agent, refractory binder, etc
