Production method of attapulgite snowmelt agent

Abstract

The invention discloses a production method of an attapulgite snowmelt agent. The production method comprises the technical essentials of mixing the ingredients of the attapulgite snowmelt agent, and then acidizing, extruding, drying, crushing, sieving, and packaging to obtain finished products. In the production method, diluted glacial acetic acid is slowly added to the attapulgite for acidizing, and the glacial acetic acid is slowly reacted with magnesium oxide, aluminum oxide and calcium carbonate in an attapulgite mixture to generate acetates of calcium acetate, magnesium acetate, aluminium acetate and the like; because the acetates in the attapulgite snowmelt agent is loaded in the mixture of attapulgite clay, ground calcium carbonate and bentonite, timely clearing the residues of the attapulgite snowmelt agent after snow melting can prevent waste water derived from melted ice and snow from flowing to farmland, greenbelts and underground without the influence on regular growth of crops and afforestation plants and road surface damage as well as corrosion action on metals. The production method of the attapulgite snowmelt agent has simple process and low production cost, and is suitable for producing various salt type snowmelt agents.

Description

technical field [0001] The invention relates to a deicing agent, in particular to a production method of an attapulgite deicing agent. Background technique [0002] Snow melting agent, also known as deicing salt and road antifreeze, is a widely used deicing agent in winter. additives, etc. [0003] "Chloride salt" deicing agents are better for snow melting and antifreeze, and the price is also cheap. After the ice or snow melts into liquid, its salt residues will accumulate in farmland and green belts, which will cause damage to crops and green plants. A large number of deaths will shorten the life of the road. The chemical reaction between the salt and the asphalt will cause the asphalt surface to fall off, and the road surface will be damaged under the action of the driving load. One of the important factors, it seriously threatens the safety of industrial facilities. After "chlorine salt" substances enter the ground, they will also pollute the local groundwater resourc...

Problems solved by technology

[0006] The disadvantage of the above-mentioned patent is that the invention adopts the method of immersing-filtering the solution-drying the whole process for 1-10 times to prepare the anti-freeze deicing agent, and its soluble salt deicing agent still contains calcium chloride, magnesium chloride and chloride Potassium and other salts

Make calcium magnesium acetate (CMA) into a saturated solution, add zeolite or diatomaceous earth to soak-filter the solution-dry the whole process 1-10 times, not only the process is cumbersome, but also the production cost is very high
