Properties:
With alkali traffic, soluble in water, strong corrosive, often used in producing potash, solid potassium hydroxide crystallization, white orthogonal has massive and flake two kinds, soluble in water spray out numerous hot. Inspiratory hind stimulates strongly respiratory or cause burns. Direct contact with skin and eyes can cause burns, once the eyes or skin contact to potassium hydroxide, rapid injured area with water will continuously flush 15 minutes of above; Oral burn the digestive tract, can be fatal.
Use:
Used for chemical production materials, also for medicine, dyestuff, light industry, etc.
