Detailed Description
The active descaling powder adopts a phosphorus-free formula and food-grade raw materials to ensure safe use. The descaling powder comprises the chemical components of anhydrous citric acid, sodium gluconate, EDTA-disodium, sulfamic acid, low-foaming surfactant and sodium p-toluenesulfonate. The preparation process of the scale remover comprises the following steps: the components are prepared according to the following mass ratio: 90-92 parts of anhydrous citric acid, 4-5 parts of sodium gluconate, 2-3 parts of sulfamic acid, 1-2 parts of sodium p-toluenesulfonate, 0-0.5 part of EDTA-disodium and 0-0.5 part of low-foaming surfactant.
The product is used in an environment with the temperature below 30 ℃, and when the product is used, the product and water are mixed according to the proportion of 3 g: 500mL of the scale remover is used in proportion, and the scale remover can be used for removing scale after being mixed with water, and has a good scale removing effect.
Example 1:
preparing the same dirt into six conical bottles with the volume percentage of each component being the largest, adding the descaling powder with the mass percentage of each component being the largest into the conical bottles with the same dirt, and mixing the descaling powder with water according to the proportion of 3 g: mixing 500mL of the mixture according to the proportion, placing the mixture into a 50mL conical flask with dirt, pouring out all liquid in the conical flask after the mixture acts for the same time, adding water to clean all the conical flasks, measuring the content of the dirt in the conical flask after the cleaning is finished, and calculating the dirt removal rate. The results are shown in FIG. 1.
When the mass of the citric acid accounts for the most of the components of the descaling powder, the dirt removal rate is higher than that of other components, the mass of the sodium gluconate accounts for about 91%, and the dirt removal rate reaches about 70.98%; when the anhydrous citric acid accounts for about 91 percent by mass, the removal rate of the dirt reaches about 94.63 percent.
Example 2
Preparing the same dirt into six conical bottles with the volume ratio of 90-92 parts of anhydrous citric acid, 4-5 parts of sodium gluconate, 2-3 parts of sulfamic acid, 1-2 parts of sodium p-toluenesulfonate, 0-0.5 part of EDTA-disodium and 0-0.5 part of low-foaming surfactant, and mixing the scale removal powder with water according to the weight ratio of 3 g: mixing 500mL of the components according to the proportion, placing the mixture in a 50mL conical flask with dirt at the temperature of 20 ℃, 50 ℃, 80 ℃, 110 ℃, 140 ℃ and 170 ℃ respectively, pouring out all liquid in the conical flask after the action is carried out for the same time, adding water to clean all the conical flasks, and measuring the content of the dirt in the filtering conical flask after the cleaning is finished. The results are shown in FIG. 2.
The removal rate of the foulants gradually decreased as the temperature increased. The change of the removal rate is large at 20 ℃, the removal rate is high, the removal rate is reduced at 80 ℃, the effect of the descaling powder is smaller along with the increase of the temperature, the dirt is removed more incompletely, and the removal rate is lower at 170 ℃.
Example 3
Preparing the same dirt into six conical bottles with the volume ratio of 90-92 parts of anhydrous citric acid, 4-5 parts of sodium gluconate, 2-3 parts of sulfamic acid, 1-2 parts of sodium p-toluenesulfonate, 0-0.5 part of EDTA-disodium and 0-0.5 part of low-foaming surfactant, respectively adding descaling powder with the water content of 1 g: 500mL, 2 g: 500mL, 3 g: 500mL, 4 g: 500mL, 5 g: 500mL, 6 g: 500mL of the mixture is mixed, and the mixture is respectively placed in a 50mL conical flask with dirt. And after the action is carried out for the same time, pouring out all liquid in the conical flask, adding water to clean all the conical flasks, and measuring the content of dirt in the filtering conical flask after the cleaning is finished. The results are shown in FIG. 3.
When the proportion is 3 g: the removal rate is higher when the volume is 500mL, and the price is more economical. The ratio of the weight ratio of 1 g: 500mL increased to 3 g: in the process of 500mL, the better the effect of the descaling powder is, the more thoroughly the dirt is removed, and the more obvious the change trend of the effect is. And the proportion is from 3 g: 500mL increased to 6 g: in the process of 500mL, the increase trend of the effect of the descaling powder is small, so that the descaling powder is relatively uneconomical and practical.
In conclusion, through experiments, the invention adopts the following active descaling powder comprising 90-92 parts of anhydrous citric acid, 4-5 parts of sodium gluconate, 2-3 parts of sulfamic acid, 1-2 parts of sodium p-toluenesulfonate, 0-0.5 part of EDTA-disodium and 0-0.5 part of low-foaming surfactant in parts by mass, and the optimal conditions for removing dirt are as follows: the temperature is 18-25 ℃, and the proportion is 3 g: 500 mL.
Comparative example
Three different descaling powders, namely active descaling powder, phosphorus-containing descaling powder and industrial-grade raw material descaling powder are adopted to treat the dirt, and the influence of the waste liquid on the environment after the dirt is removed by the different descaling powders is compared. The invention comprises 90-92 parts of anhydrous citric acid, 4-5 parts of sodium gluconate, 2-3 parts of sulfamic acid, 1-2 parts of sodium p-toluenesulfonate, 0-0.5 part of EDTA-disodium and 0-0.5 part of low-foaming surfactant, the temperature is 18-25 ℃, and the proportion is 3 g: 500 mL. The results are shown in FIG. 4.
As can be seen from fig. 4, when the active descaling powder is used, the influence of the waste liquid after the removal of the scale on the environment is smaller than that of the other two descaling powders. When the phosphorus-containing descaling powder is used, the waste liquid contains a large amount of phosphorus elements, which has great influence on the environment. When the industrial-grade raw material descaling powder is used, the influence on the environment is far higher than that of the active descaling powder. The reason is mainly because the phosphorus-containing descaling powder is used, the waste liquid generated after descaling contains a large amount of phosphorus elements, excessive phosphorus easily affects production and life, water eutrophication and red tide generate sediment circulation, and excessive phosphorus in the edible product can cause arrhythmia, nervous system disorder and different bone growth. The descaling powder is made of industrial-grade raw materials, and industrial-grade compounds such as improper cleaning and improper contact can affect the body after being used by people. Some raw materials have bitter and astringent taste, so that the drink has poor taste when being used for cleaning drinking articles, has a corrosive effect on skin, cannot be inhaled, can affect respiratory tract and can cause eczema for a long time. This result also demonstrates the superiority of using the active descaling powder to treat the scale from the side.
