Uses of alkali

The main chemical components of flake alkali, burnt alkali, pyroalkali and liquid alkali are all sodium hydroxide, and their main uses are also similar. The difference between them lies in their different forms and different alkalinity strengths. So what are the uses of flake alkali, burnt alkali, pyroalkali and liquid alkali? We will give you a detailed answer below. You can choose to use flake alkali, burnt alkali, pyroalkali and liquid alkali according to your needs.

Product Usage

1. Used in the production of paper and cellulose pulp;

2. Used in the production of soaps, synthetic detergents, synthetic fatty acids and the refining of animal and plant oils.

3. In the textile printing and dyeing industry, it is used as a desizing agent, scouring agent and mercerizing agent for cotton cloth.

4. Used in the chemical industry to produce borax, sodium cyanide, oxalic acid, phenol, etc.

5. The petroleum industry uses it to refine petroleum products and in oilfield drilling mud. It is also used in the production of aluminum oxide, surface treatment of metallic zinc and metallic copper, as well as in glass, enamel, leather making, medicine, dyes and pesticides.

6. Food-grade products are used as acid neutralizers in the food industry, as peeling agents for citrus fruits and peaches, as detergents for empty bottles and cans, and as decolorizers and deodorizers.

7. It can also be used as an alkaline desiccant. Alkali is widely used in the national economy and is required by many industrial sectors. The sector that uses the most alkali is the manufacture of chemicals, followed by papermaking, aluminum smelting, tungsten smelting, rayon, artificial cotton and soap manufacturing. In addition, a large amount of alkali is also used in the production of dyes, plastics, pharmaceuticals and organic intermediates, the recycling of old rubber, the production of metallic sodium, the electrolysis of water and the production of inorganic salts, and the production of borax, chromium salts, manganates, phosphates, etc.

Toxicity protection

It is extremely corrosive. Its solution or dust splashes onto the skin, especially onto the mucous membrane, and can produce soft scabs and penetrate into deep tissues. Burns leave scars. If it splashes into the eyes, it will not only damage the cornea, but also cause damage to the deeper tissues of the eye. If it accidentally splashes on the skin, rinse immediately with clean water for 10 minutes; if it splashes into the eyes, rinse immediately with clean water or saline for 15 minutes, and then inject 2% novocaine. If the condition is serious, send to hospital for treatment immediately. The maximum allowable concentration of alkali dust in the air is 0.5 mg/m3. Operators must wear work clothes, masks, protective glasses, rubber gloves, rubber aprons, long rubber boots and other labor protection supplies when working. A neutral and hydrophobic ointment should be applied to the skin. The production workshop should be well ventilated.
