通过主物料的筛选、融雪剂配比的优化及缓蚀剂的添加,研制出高效、低腐蚀且植物友好型环保融雪剂。对各融雪剂样品的融冰能力、腐蚀性和植物影响进行了对比性测试。结果表明,该植物友好型低腐蚀融雪剂在-25℃寒冷条件下,30 min内融冰量可达传统氯化钠型融雪剂的数倍,体现出明显的高效性;相比于传统氯化钠型融雪剂,该融雪剂的水溶液在72 h内对钢铁的腐蚀性平均降低了93.29%,体现出良好的低腐蚀性;在6 d以内,本融雪剂产品未对常用绿化植物冬薄荷产生明显破坏,植物生长良好,环保性能远胜于传统氯化钠型融雪剂,具备植物友好性。

A novel plant-friendly and environmental-friendly snow-melting agent with low corrosion is developed via the screening of components,the optimization of the ratio of snow-melting agent and the addition of corrosion inhibitors.The ice melting ability,corrosion property and plant impact of various snow-melting agent samples are comprehensively tested.It is indicated that the developed sow-melting agent melts ice several times as much as traditional sodium chloride-based snow-melting agent does within 30 min at -25℃,exhibiting a high efficiency.Compared with traditional sodium chloride snow-melting agent,the corrosion of the aqueous solution of the developed snow-melting agent to steel drops by about 93.29% within 72 h,reflecting a low corrosion property.The novel snow-melting agent has also generated hardly damage to winter mint,a kind of commonly used green plant,in six days.This snow-melting agent exhibits plant-friendly and environmental-friendly properties in comparison to traditional sodium chloride-based snow-melting agent.
