preparation example Construction
[0023] The preparation method of the solid ice-melting composition for substation equipment deicing of the present invention comprises the following steps:
[0024] Step 1, adding soda ash to sodium chloride and stirring to mix evenly to obtain powdery mixture A;
[0025] Step 2. After mixing trichloroacetic acid and other components, heat and dry at 80° C. for 20-30 minutes to obtain mixture B;
[0026] Step 3. Crushing the mixture B into the desired particle size as required, stirring and mixing the mixture A and the mixture B under dry conditions to obtain a solid ice-melting composition.
Embodiment 1
[0029] Take 63 grams of sodium chloride and 24 grams of soda ash and stir and mix evenly to obtain a powdery mixture A, then mix 10 grams of trichloroacetic acid, 1 gram of sodium benzoate and 2 grams of calcium carbonate and heat and dry at 80 ° C for 23 minutes to obtain a mixture B, and then crush the mixture B into powder and add it into the mixture A and stir to mix evenly to obtain 100 grams of ice-melting composition.
Embodiment 2
[0031] Take 60 grams of sodium chloride and 27 grams of soda ash and stir and mix evenly to obtain a powdery mixture A, then mix 13 grams of trichloroacetic acid, 1 gram of zeolite and 2 grams of calcium carbonate and heat and dry at 80°C for 20 minutes to obtain a mixture B , and then the mixture B was crushed into powder and added to the mixture A and stirred evenly to obtain 100 grams of ice-melting composition.
