Problems solved by technology

[0002] At present, there are few applications of deicing agents for snow melting and deicing of substation equipment in substations, and there are limited examples for reference. Therefore, physical methods such as manual deicing or thermal charging of equipment are generally used. These methods not only exist Big security risks, but also need to invest a lot of cost, low income
Commercially available ice-melting agents generally use calcium chloride and sodium chloride as the main raw materials. However, spraying sodium chloride powder and calcium chloride powder will not produce an immediate effect. Slow melting, in the slow melting process, it is easy to cause the secondary crystallization of liquid water on the substation equipment, and these ice-melting agents are corrosive to the substation equipment, therefore, the existing sodium chloride Or the deicing agent with calcium chloride as the main raw material has insufficient deicing effect

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.

Abstract

The invention discloses a solid ice-melting composition for deicing substation equipment and a preparation method thereof, which is characterized in that, in terms of mass percentage, the solid ice-melting composition is mainly composed of the following components: 60-63 % sodium chloride, 24‑27% soda ash and 10‑13% trichloroacetic acid. The solid ice-melting composition for substation equipment deicing and the preparation method thereof of the present invention achieve the purpose of rapidly melting ice and snow by increasing the initial ice-melting rate of the ice-melting composition. At a temperature of 5°C, its The initial ice-melting rate can reach 44.1mL / min, which reduces the corrosion of the substation equipment to a certain extent, prevents secondary icing of the substation equipment, and solves the shortcomings of the existing technology.

Description

technical field [0001] The invention relates to the field of snow removal and deicing for substation equipment, in particular to a solid ice-melting composition for deicing substation equipment and a preparation method thereof. Background technique [0002] At present, there are few applications of deicing agents for snow melting and deicing of substation equipment in substations, and there are limited examples for reference. Therefore, physical methods such as manual deicing or thermal charging of equipment are generally used. These methods not only exist Larger potential safety hazards require greater investment and lower returns. Commercially available ice-melting agents generally use calcium chloride and sodium chloride as the main raw materials. However, spraying sodium chloride powder and calcium chloride powder will not produce an immediate effect. Slow melting, in the slow melting process, it is easy to cause the secondary crystallization of liquid water on the subs...
