1: The antifreeze liquid for hydraulic support is used for the antifreeze of hydraulic equipment such as hydraulic support in the cold season ground storage, well maintenance and factory transportation, and is used as the power transmission medium of the hydraulic support system in coal mine to meet the requirements of the use of hydraulic support and its pump station under low temperature conditions, which can effectively protect the hydraulic support from being damaged by low temperature under cold conditions and extend its service life.
2: In order to ensure the freezing point of the antifreeze of the hydraulic support, the original liquid must be used directly during installation, and the antifreeze of the hydraulic support shall not be diluted when used according to the local minimum temperature, which shall not be lower than the minimum use temperature of the antifreeze of the model. That is, it is used directly within the range of not less than -40C.
