Alkali, characterized by its alkaline nature, comprises a substantial concentration of hydrogen and oxygen radicals. As a potent alkaline chemical, it possesses robust corrosive properties, facilitating the dissolution of dense substances like fats, while also exhibiting an elevated propensity for chemical reactions with diverse compounds.

Usage of Alkali Products

Alkali finds extensive application across a spectrum of industries, including the chemical sector, textile printing and dyeing, smelting, adhesives, daily chemicals, medicine, and paint production. 

In these domains, alkali serves as a pivotal ingredient for a myriad of functions. It is instrumental in the production of oxalic acid, baking soda, water softeners, and neutralizers. These diverse applications underscore alkali's multifaceted role in shaping and enhancing processes across various industrial landscapes.

Attention for Usage of Alkali 

The handling of alkali demands careful consideration due to its potential to inflict damage and corrosion upon various materials, including paints, metals, fabrics, plastics, and skin. Solid forms of alkali exhibit robust chemical reactivity, warranting caution when dealing with metals like aluminum. 

While typically non-flammable in its dry state, alkali mixed with water has the potential to ignite fires. Given the toxic nature of many household alkali-based products, prudent measures must be taken during usage. 

For instance, exercising caution while using lye-based polish for silverware cleaning is imperative, as even its noxious odor can pose risks. Furthermore, refrain from employing lye paint remover in inadequately ventilated spaces.

During alkali usage, it is advisable to maintain the alkali temperature below 80 ℃ (excluding blue lye) to prevent the escape of alkaline gases. When retrieving parts from alkali solutions, a gradual and deliberate approach should be adopted to avert spillage. 

The utilization of protective attire is recommended during alkali preparation. In the event of alkali contact with skin, immediate rinsing with warm water should be followed by a rinse with a 1% acetic acid solution, succeeded by cold water, and ultimately application of glycerin and Vaseline to safeguard the skin.

Should alkali come into contact with the eyes, immediate rinsing with clean water or normal saline for 15 minutes is essential, with severe cases warranting prompt medical attention and hospital treatment.
