Soda flakes,also known as sodium hydroxide,exist in the form of white translucent flakes and are made by heating and thickening the liquid alkali once and for all.But in addition,some processing is needed because there may be impurities inside and the color is not clean,so a series of color matching treatments are needed to make products that meet the standards.Let's take a look at how the operator handles color matching.
1.Operators of soda ash must wear labor protection equipment before going on duty.
After the liquid alkali in the mixing tank settles for 2 hours,the mixing process begins.
During the precipitation process,the operator should adjust the air valve to maintain the temperature of the liquid alkali at 450-500.
4.First,add sodium nitrate to precipitate impurities,then add sulfur powder to adjust the color of the liquid alkali and accelerate the precipitation of impurities.
5.Place a small amount of liquid alkali into the sampling tray,observe the color as milky white,and send it to the laboratory for testing.
After the inspection report shows that it is qualified,the liquid alkali can be injected into the tablet alkali machine for alkali extraction.
7.Adjust the height of the inclined hopper to ensure that the drum and liquid alkali are always in contact.
8.Turn on the circulating water pump and observe whether the circulating water flow meets the alkaline extraction liquid level.When encountering alkaline water level,notify the packaging personnel to carry out work.Turn on the power switch of the device and the power switch of the winch.
9.Turn on the vertical alkali pump and transport the liquid alkali to the production equipment.Pay attention to observe that the alkaline rate should not be too fast or too slow.
After the liquid alkali in the mixing pot is emptied,the power switches of the equipment and the dryer can be turned off.
That's all for today's content.After a series of color matching treatments,we can produce soda ash that meets the standards.When heating,pay attention to the temperature.
