Potassium formate is an organic salt with the chemical formula of HCOOK. It is a white solid, easy to absorb moisture, has reducibility, can react with strong oxidants, and has a density of 1.9100g/cmthree, easily soluble in water, non-toxic and non corrosive.The aqueous solution is colorless and transparent, and the specific gravity of saturated solution is 1.58 g/cmthree。
1. As a drilling fluid, completion fluid and workover fluid with excellent performance, they are widely used in the oilfield industry;
2. In the snow dissolving agent industry, the acetic acid smell in the air is too strong after the additive acetate melts snow and causes a certain degree of corrosion to the ground, etc., and potassium formate not only has good snow melting performance, but also overcomes all the drawbacks of acetate and is praised by citizens and environmentalists;
3. In leather industry, it is used as camouflage acid in chrome tanning process;
4. Used as reducing agent in printing and dyeing industry;
5. It can also be used as an early strength agent for cement slurry, as well as in mining, electroplating, foliar fertilizer for crops and other industries.[1]
