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.
