Storage conditions
1. Use plastic bags or kraft paper lining, external carton, sack or polypropylene woven bag to seal the packaging, and store in a dry warehouse.
2. The packaging should be completely sealed to prevent moisture. Do not store or transport with acids. Store in a dry and ventilated warehouse. Prevent damp, rain and package damage during transportation.

Stability
1. Do not co-store with acids. Aluminium hydroxide gel is a white viscous suspension colloid, and a small amount of water can be precipitated on standing.
2. There is no fixed chemical composition. Generally refers to aluminum hydroxide [Al(OH)3], aluminum oxide hydrate (Al2O3·xH2O) or water-insoluble basic aluminum sulfate [Al2(SO4)(OH)4], etc. There are also reports suggesting that it is caused by water-insoluble tetra-alkali Formula aluminum sulfate, aluminum dihydroxide polymer [Al2SO4(OH)4·xH2O·2Al(OH)3]n. It is transparent when mixed with linseed oil.

Function
1. Used as a mordant and analytical reagent.
2. Used in petroleum, chemical, fertilizer, natural gas and environmental protection industries. The main function is to increase the distribution of gas or liquid, and support and protect the catalyst with low strength.
3. Printing inks, painting pigments, crayons, rubber fillers.
