Description
Technical field
The present invention relates to a kind of bulk granular goods stacking and transportation deicing fluid and preparation method thereof, this deicing fluid is mainly used in and prevents that the bulk granular goods from freezing in railway, transport by road and stacking process, thereby avoids influencing the turnover of production and vehicle.
Background technology
The bulk granular goods loads and unloads in the winter time, in the stop, transportation, easily freeze, and is difficult to loading and unloading, relates to many departments and units such as metallurgy, coal, water power, traffic, railway, and not only influence is produced, and has a strong impact on the turnover of vehicle.Cause the tremendous economic loss also for railway, colliery, harbour
For many years, once adopted many methods to solve the problem that the bulk granular goods freezes both at home and abroad, as adding MgC1 in vibration, explosion, electrically heated, defrozing silo, the coal
2, CaC1
2, method such as car body paraffinize and diesel oil, and these method labour intensity are big, the cost height, car body is contaminated, cargo mass is also influenced, fails fundamentally to solve the problem that the bulk granular goods freezes.
Chemistry deicing fluid is easy to use because of it, is not subjected to area, place to limit advantages such as less energy consumption, instant effect.Become the antifreeze important means of aqueous particulate goods transportation in winter.Chemistry deicing fluid is exactly to join with a spot of chemical substance in the particulate matter such as moisture breeze.The freezing point of water in the breeze is reduced.This moisture can not freeze under general low temperature, even freeze under the lower temperature, its ice crystal structure also changes, and freezing strength weakens, and just can make the scars fragmentation with less external force, the purpose of reach antifreeze, thawing.
Qualified deicing fluid requires to have good antifreezing effect, vehicle is not caused corrosion. and nontoxic or low toxicity, avoid environment is polluted, modest viscosity is convenient to spray, and long-term storage did not lose efficacy, and was cheap etc.
Deicing fluid unloads, reduces aspect economy, convenience, effective such as vehicle stopping time, raising conveying efficiency at the bulk granular goods, be highly suitable for moisture antifreeze transportation and stackings of easily freezing goods in bulk such as breeze, ore.
Therefore, provide a kind of nontoxic, tasteless, with low cost, convenient production, the deicing fluid of being convenient to operation enforcement and compliance with environmental protection requirements just becomes the technical barrier that present technique field urgent need will solve.
Summary of the invention
One of purpose of the present invention provides a kind of nontoxic, tasteless, with low cost, and convenient production is convenient to the bulk granular goods deicing fluid of operation enforcement and compliance with environmental protection requirements.
For achieving the above object, the present invention has taked following technical scheme:

(5) EDTA dissolving back adds sodium acetate and Sodium Nitrite;
(6) add trolamine afterwards;
(7) add strontium nitrate afterwards again;
(8) adding is dissolved good cationic polyacrylamide in advance with another part water again;
(9) to be mixedly promptly get the deicing fluid product after evenly.
A kind of optimized technical scheme is characterized in that: the purity of described calcium chloride is greater than 99%.
A kind of optimized technical scheme is characterized in that: described benzotriazole, trolamine, Sodium Nitrite, sodium acetate, EDTA and strontium nitrate are analytical pure.
A kind of optimized technical scheme is characterized in that: the molecular weight of described cationic polyacrylamide is greater than 5,000,000.
Among the present invention, utilize calcium chloride to reduce the freezing point of solution, the effect of benzotriazole, trolamine, Sodium Nitrite, sodium acetate, EDTA is that to reduce deicing fluid be that to lower the pungency of skin, the effect of cationic polyacrylamide be the viscosity of increase system to the effect of the burn into strontium nitrate of steel copper aluminium, makes its easier wall built-up.The freezing point of this deicing fluid can reach-46 ℃.And skin irritation is very weak, and performance index such as its freezing point, corrodibility, density, viscosity meet " bulk granular transportation of cargo deicing fluid technical qualification (TB/T 3208-2008) " fully.In bulk granular transportation of cargo process, spray this deicing fluid and prevent that goods from freezing in transportation, for unloading of goods saved the plenty of time, thereby quicken the train turnover, will produce huge economic benefit and social benefit.
Deicing fluid of the present invention can proportioning be finished under the normal temperature state, need not other warming-up devices of task.Spray after at normal temperatures its proportioning being finished or be coated on transport of loose cargo compartment wall and the goods, can prevent effectively that goods from freezing under arctic weather.And can not cause environmental pollution, cargo mass is not exerted an influence.Transport enterprise and the existing huge economic benefit of goods in bulk client also there is social benefit of environment protection.
