As is well known,caustic soda can be used as a water purifier,and its hydroxide can be used to adjust the pH value of water.However,the hydroxide of caustic soda can also be used to manufacture degreasers,which are widely used in daily life.Let's take a look together next.
Let's talk about the items and steps required to prepare 1kg degreaser.Firstly,prepare 850 grams of water and inject it into the oil tank.Then,add 21 grams of caustic soda,25 grams of sodium sulfate,5 grams of sodium gluconate,2 grams of sodium alginate,and Sg of sodium hexametaphosphate to the water in the oil tank in sequence,stir and dissolve.Then pour 50 grams of water into another plastic bucket,add 3 grams of additive A and 2 grams of additive B,stir for 5-10 minutes to completely dissolve,and then pour into the above-mentioned oil removal tank.The remaining 37 grams of water are poured into it to obtain the ambient temperature oil removal agent.The temperature range for using degreaser is 5-45℃.Within this range,the higher the temperature,the better the degreasing effect and the faster the speed.For oil stains on general metal surfaces,only soaking in this degreaser for about 10 minutes can achieve satisfactory degreasing effect.

The determination of oil removal time is based on the continuous and uniform water film on the surface of the workpiece after oil removal cleaning as a standard for determining the optimal oil removal time of the workpiece.The formula of flake alkali can be used to remove rust proof thin oil layers or moderate or mild oil stains on the surface of steel,but for thick oil layers or paste like oil stains,it is necessary to first use surface scraping method to preliminarily remove them,and then use the degreaser to remove them.
The above introduction is the relevant content for today.Soda flakes can not only be used as water purifiers,but also as oil removers.It is widely used in various fields of the chemical industry,as well as in agriculture and manufacturing.If you have any further questions,please feel free to consult us at any time!
