Show Color Type Of Environmental Except Ice Melting Agent Development And Performance Study

As the city scale unceasingly expands, the winter snow on city roads and the impact of urban life is more and more outstanding. Especially the winter in north China, sweeping the snow in a prompt way becomes significantly important in maintaining the unobstructed and safe traffic.The appearance of snow melting agent attributes to the inconvenience which brought to the people around the world as well as the loss of economy. Nowadays, sweeping snow by manpower, machine snow plough and snow melting agent are main approaches in urban. Furthermore, snow melting agent was wildly used around the world due to the low costs, low demanding of manpower and material resources moreover the expeditous snow melting.Calcium chloride type snowmelt agent is a kind of hygroscopic strong, easy ChaoXie substances, when in contact with snow and ice, which can make the freezing point to reduce the effect of melting. Calcium chloride type snowmelt agent corrosion rate under the control of national permitted range of automobi damage, the only type of sodium around 3% of snowmelt agent. Some snowmelt agent usually contains some colorings, some dyeing agent has toxicity to animals and plants will cause harm. Therefore, developed a snowmelt effect is good, corrosive relatively small and has the safety of snowmelt agent were removing ice is important.With calcium chloride as main raw materials, add the shells, corrosion inhibitor and burning for plant growth of the plants of calcium beneficial Snow-melting agent, through experiments and the best proportion, the experimental results showed that homemade Snow-melting agent ice melt ice melt with the amount of time increases. In conclusion, the ice-melting effect four types of agents was that homemade ice melting agent>calcium chloride >salt> the melting agent. Homemade ice melting of metals in the little corrosive agents, no influence on plant growth. And meet the GB/T 23851-2009 road except ice melting agent standards. By adding shells burn them except ice melting agent, and according to the present shallow pink melting snow melting agent after the color changes, the solution for the control of melting, avoid wasted dosage. Based on infrared mapping, scanning electron spectrometry analysis of main component, snowmelt agent for Cl, Ca, O three elements.
