Problems solved by technology

[0005] According to relevant information, according to the method of ASTM F1111, there is no pavement deicing agent that does not meet the requirements of this test. Generally, pavement deicing agents are relatively easy to pass this test.
However, in actual use, some pavement deicing agents used in western countries have caused corrosion of cadmium-plated parts such as aircraft landing gear and connectors.
The reason is mainly because the test method s

Example

[0032] Perform full immersion corrosion test on Examples 1 to 6

[0033] ① For Examples 1-6, follow the ASTM test standard in "American Aviation Material Technical Specifications-About Flight Runway and Slideway Deicing / Anti-Icing Solid Containment" (AMS1431D Compound, Solid Runway and Taxiway Deicing / Anti-Icing) F483 standard conducts full immersion corrosion test.

[0034] ②The ASTM F483 standard measurement procedure is to take a metal piece with a size of 50.8×25.4×1.6mm and place it in a test solution of a specified concentration (15%) made of deicing agent, under one atmosphere of pressure and at a constant temperature of 38±3℃ , Soak for 24 hours, record the weight change and appearance corrosion and discoloration of the metal sheet before and after soaking, the unit of the test result is mg / cm 2 ·24 hours.

[0035] ③The test results are shown in Table 2 below:

Abstract

The invention discloses a deicing snow-melting agent. A formate is taken as a main ingredient of the deicing snow-melting agent; the deicing snow-melting agent also contains a plurality of additives such as metasilicate, sodium carbonate, organic phosphate containing phosphoryl groups, and cadmium plated metal sheet corrosion inhibitor. The deicing snow-melting agent possesses excellent ice removing capacity, ice preventing capacity, and snow melting capacity; corrosion is less; corrosion on carbon steel metal and concrete is less; and corrosion on aluminium and magnesium alloy, and cadmium plated metal materials used on airplanes is extremely less; biodegradation of the deicing snow-melting agent can be realized easily; oxygen consumption in degradation is less; environmental protection performance is excellent; and the deicing snow-melting agent is capable of removing ice rapidly with high efficiency.

Description

technical field [0001] The invention relates to a deicing and deicing agent, in particular to an ecological deicing and deicing agent mainly composed of formate. Background technique [0002] Existing chlorine salt deicing agents due to Cl - The corrosiveness of ions is often added with rust inhibitors (anticorrosion agents). Although the corrosiveness to metals and road construction materials is alleviated, the corrosiveness is still very prominent, and Cl - Ions have an impact on soil and vegetation, and endanger plant growth. Biological deicing agents such as food crops, papermaking waste liquid, wine by-products, fat sugar products, etc. are low in cost and have no environmental pollution, but their deicing effects are average. The urea deicing agent is decomposed into ammonia, and the calcium nitrate and magnesium salt deicing agent contains nitrate, which makes the water body eutrophic. Alcohol deicing agents such as ethylene glycol and glycerin enter the water body...
