High-efficiency antiseptic antifreezing agent for coal transportation and method for preparing same

Abstract

The invention provides a kind of coal transportation with highly effective to guard against corrosion the antifreeze, its component was: Glycol, calcium chloride, triethanolamine, with deionized water. The above coal transportation highly effective anticorrosion antifreeze preparation method includes: (1) solution configuration: The calcium chloride, joins in the deionized water, namely made has been ready to be used the fluid, (2) mixed the process: Joins the triethanolamine makes is ready to be used in the fluid, makes the reserve fluid, again glycol if in the reserve fluid, then continues to stir for a hour, causes the temperature drop to the room temperature, like this, has made the end product. The invention discloses testing many times in the foundation, screened pour point depressant, caused the antifreeze the solidification point greatly to reduce, had achieved -66deg.C, its anti- freezing temperatures has achieved -40deg.C, therefore had the fine low freezing point performance, also the stability was extremely good, has satisfied north the winter coal transportation request. After simultaneously in order to avoid pour point depressant oxidizing corrodes the freight car, but also has used the inhibitor technology, provides the long-term anticorrosion for the train freight car, has guarded against the rust function.

Description

technical field [0001] The invention relates to an antifreeze agent and a preparation method thereof, in particular to an antifreeze agent used to prevent washed coal from freezing during transportation, in particular to a high-efficiency anti-corrosion antifreeze agent for coal transportation and a preparation method thereof. Background technique [0002] After the mined raw coal has been washed, as much as 20% of the water will remain in the coal in the car when it is loaded, and my country's coal reserves are mainly distributed in high-latitude cold regions above 35 degrees north latitude, so for many years , During the transportation of coal in winter in the north, a large amount of coal will freeze on the inner wall of the carriage. At this time, the method of removing the frozen coal in the carriage is mainly to use manual or semi-mechanical methods, which undoubtedly have the disadvantages of low efficiency and time-consuming, and Prolonged the circulation time of train...

[0002] After the mined raw coal has been washed, as much as 20% of the water will remain in the coal in the car when it is loaded, and my country's coal reserves are mainly distributed in high-latitude cold regions above 35 degrees north latitude, so for many years , During the transportation of coal in winter in the north, a large amount of coal will freeze on the inner wall of the carriage. At this time, the method of removing the frozen coal in the carriage is mainly to use manual or semi-mechanical methods, which undoubtedly have the disadvantages of low efficiency and time-consuming, and Prolonged the circulation time of train wagons, seriously affected the transportation of coal, and caused great economic losses

In order to solve this problem, some antifreeze agents with similar performance are used in actual use, but their antifreeze temperature can only reach -15°C, which cannot meet the requirements of the north. No special antifreeze agent for coal transportation has been found so far. Related news about antifreeze
