Embodiment Construction
[0033] Below in conjunction with embodiment the present invention will be further described:
[0034]The production method of the attapulgite rapid deicing and deicing agent is characterized in that (1) the ingredients of the attapulgite mixture are input into the mixer for stirring, and after stirring evenly, they are added to the soaking pool; (2) the diluted glacial acetic acid is slowly added to soak Carry out acidification treatment in the attapulgite mixture in the pool, and the acidification time is controlled at 36 hours; (3) input the acidified attapulgite mixture into an extruder and extrude into flakes, the thickness of the flakes≤3 mm; (4 ) Transport the flakes to a drum dryer for slow drying, the drying time is 4 hours, and the drying temperature is controlled at 65-75°C; (5) Input the dried flakes into a pulverizer for crushing and screening , the particle fineness is controlled at 0.25-5mm, and the water content is ≤1.5%. The sieved particles are semi-finished p...

Abstract
The invention discloses a production process of a rapid attapulgite ice and snow melting agent, technically characterized in that the ingredients of the rapid attapulgite ice and snow melting agent are mixed, acidulated, extruded, dried, crushed, screened, mixed and packaged into a finished product. The rapid attapulgite ice and snow melting agent contacts with snow and ice, generates heat to rapidly melt ice or snow into water which is absorbed by the rapid attapulgite ice and snow melting agent and converted into gelatinous matter. The rapid attapulgite ice and snow melting agent is an irregular particle mixture, is beneficial to being uniformly sprinkled on a snow-melting construction site, not only can rapidly melt ice and snow, and effectively prevent the melted snow or ice from being frozen again, thereby improving the snow-melting effect, but also loosening the deposited snow, and being beneficial to uniformly removing, collecting and cleaning the snow-melting site. The rapid attapulgite ice and snow melting agent has simple production process, low production cost and remarkable snow-melting effect; and the invention is suitable for producing various salt rapid ice and snowmelting agents.
Description
technical field [0001] The invention relates to a deicing agent, in particular to a production method of an attapulgite rapid ice-melting deicing agent. Background technique [0002] Snow melting agent, also known as deicing salt and road antifreeze, is a snow removal substance widely used 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 th...
