Alkali asbestos packed column
Alkali asbestos packed column Details:
Name: Alkali asbestos packed column
Specification: 1.5m*4mm, 20-30 mesh
Model: Alkali asbestos
Maximum operating temperature: 260°C
Application: Absorption of carbon dioxide and moisture
Caustic soda Asbestos is a chemical reagent. It is a granular hard substance with uniform properties made from asbestos fiber after being treated with caustic soda (ie, sodium hydrogen yang). Its important feature is that it easily absorbs carbon dioxide and produces sodium bicarbonate or sodium carbonate. The chemical industry uses this feature to determine the content of carbon dioxide in a certain gas in order to control the content of carbon dioxide in the production process. The chemical reaction equation is as follows: NaOH+CO2=NaHCO32NaOH+CO2=Na2CO3+H2O In the metallurgical industry, the weight difference before and after the caustic soda asbestos test is commonly used to determine the carbon content in steel materials. Fruit and vegetable cold storage warehouses use caustic soda...
