Condition is affected, and has heat of certain scope of application including heating cable method, solar energy accumulation method, geothermal method etc.
Power snow melt deicing method makes ice dissolution using heat, has many advantages, such as that environmental protection, snow melt deicing are thorough, thus becomes research both at home and abroad
Emphasis and hot spot.Microwave ice removing technology also belongs to the scope of heating power snow melt clearing ice technology, is used for aircraft wing deicing earliest, will
Microwave applications in the greatest problem that road deicing faces be tradition gather materials making pavement of road microwave adsorption heat-emitting efficiency it is very low,
It is difficult to realize fast snow melting deicing.U.S.'s discovery taconite in 2003 has extremely strong absorption heating functioin to microwave, and proposing will
Taconite gathers materials as road, realizes fast snow melting deicing.The research discovery microwave of domestic Chang An University has with magnet to be coupled
Heating effect further provides for magnetic iron ore to be broken into and gathers materials making bituminous pavement to improve road microwave ice removing efficiency
Research is imagined.The study found that magnetic iron ore gathers materials under microwave action, rate of rise in temperature is quickly；Commonly gather materials in microwave action
Under, reach 20 times that the mutually synthermal time used is about the time used in magnetic iron ore gathers materials.This explanation is using in conjunction with magnetic iron ore
Coupling microwaves heating technique achieves good progress for road deicing, still, keeps the coast is clear very crucial, Hen Duocheng
City has all made in detail and strict requirements the road dredging time after ice and snow, so developing a kind of microwave ice removing road use
Material becomes the most important thing.
