PC-1型五节机保车组的运用经验表明,用1915号铝合金制造的车辆货物间离水格子,时常损坏和不能使用。例如,在一家车辆修理厂对一级大修的178个机保车组的调查证实,几乎50%的铝合金制离水格子受到不同程度的腐蚀损坏。而货车车体铝制内墙板则很少受到腐蚀破坏或者根本没有腐蚀。金属的腐蚀是由于所运货物的影响,以及用热碱水处理机保车造成的。铝墙板和离水格子支架的腐蚀破坏程度取决于它们与碱溶液接触的时间长短。车墙板仅与洗涤液有短时间的接触,而离水格子则长时间处在弱
PC-1-type five-car team experience shows that the use of 1915 made of aluminum alloy vehicle cargo water from the grid, often damaged and can not be used. For example, a survey of 178 machine-builders belonging to a fleet of overhauls at a vehicle depot confirmed that almost 50% of the aluminum alloy-made water drains were damaged to varying degrees by corrosion. The wagon body aluminum interior wall panels are less corroded or corroded. Corrosion of the metal is due to the effects of the cargoes shipped, as well as the handling of van with hot caustic. The degree of corrosion damage to the aluminum wall panels and the water grid sub-brackets depends on how long they are in contact with the alkaline solution. The car wallboard only has a short contact with the washing liquid, while the water lattice is weak for a long time
