Storage method

Solid sodium hydroxide is packed in steel drums with a thickness of 0.5 mm, tightly sealed, and the net weight of each drum does not exceed 100 kg; Steel drums with full openings outside or in the middle of plastic bags or double-layer kraft paper bags; Threaded glass bottles, iron-capped glass bottles, plastic bottles or ordinary wooden cases outside metal barrels (cans); The threaded glass bottle, plastic bottle or tinned steel barrel (can) is sheathed with a bottom plate lattice box, a fiberboard box or a plywood box;

Tinned steel drums (cans), metal drums (cans), plastic bottles or corrugated boxes with metal hoses. Packaging containers should be complete, sealed and marked with "corrosive substances".

Sodium hydroxide is slightly corrosive to glass products, and both of them will produce sodium silicate, which will make the piston in the glass instrument stick to the instrument. So don't use a glass bottle stopper when holding sodium hydroxide solution, otherwise the bottle cap may not open.

If the glass container is filled with hot sodium hydroxide solution for a long time, it will also cause damage to the glass container.
