We all know that caustic soda can be used as a water purification agent,and its hydroxide ions can be used to adjust the pH of water.However,the hydroxide ions of caustic soda can also be used to make degreasers.Oil removers are also widely used in daily life.Let's take a look together at what's going on.
Let's first discuss what items are needed and what steps are required to configure a 1kg degreaser:
1.Firstly,prepare 85g of water and inject it into the degreasing tank.Then,add 21g of tablet alkali,25g of sodium sulfate,5g of sodium gluconate,2g of sodium alginate,and Sg of sodium hexametaphosphate into the degreasing tank water in sequence,and stir to dissolve them.

2. Then pour 50g of water into another plastic bucket and add 3g of additive A and 2g of additive B to this bucket, stirring for 5-10 minutes to dissolve completely. Then pour it into the above-mentioned oil removal tank and pour the remaining 37g of water into it to obtain the room temperature oil removal agent.
The temperature range for the use of degreaser is 5-45 ℃, within which the higher the temperature, the better the degreasing effect and the faster the speed. For general metal surface oil stains, soaking in this degreaser for about 10 minutes can achieve satisfactory degreasing effect. The determination of oil removal time is after oil removal and water washing. The water film on the surface of the workpiece is a continuous and uniform water film, which is a standard for determining the good oil removal time of the workpiece.
The formula of caustic soda can be used to remove rust proof thin oil layers or generally mild oil stains on the surface of steel. For thicker oil layers or paste like oil stains, it is necessary to first scrape the surface to remove the oil, and then use this degreaser to remove the oil. caustic soda can not only be used as a water purifier but also as a degreaser. The use of caustic soda is very extensive. It is widely used in various fields of the chemical industry, as well as in agriculture and manufacturing.
