保证产品在储存、运输及装卸过程中避免受潮，否则 可能导致产品生锈。 高温、高湿、亚硫酸气体环境不利于产品的储存，不 要长时间存放在此类环境中。 在储存及运输过程中，需防止发生钢卷的侧翻、滚动 以及散包。 强碱清洗和超声波清洗会对表面涂层造成损伤，建议 选用中低碱性的脱脂剂，尽量不使用超声波。 使用某些有机溶剂擦拭表面有可能会损伤表面涂层， 建议试验后再使用。 如需磷化处理，磷化液温度和游离酸浓度不易过高， 否则会对表面涂层造成损伤。 由于时效的影响，钢板及钢带的力学性能和加工性能 会随着时间的延长而变差，如屈服强度和抗拉强度上 升、断后伸长率下降以及加工性能降低等，建议尽早 使用。 Storage and Transportation Products must be kept from moisture during storage, transportation and loading/unloading, otherwise they may get rusted. ● It is recommended that plastic bag could be added in the package to avoid moisturized products. ● It is to the disadvantage of the product storage to have...
