Problems solved by technology

[0031] Due to the use of pure halide deicing agents, the salt content in the soil increases, which reduces the water and nutrients absorbed by the plants, and causes the hardening of the green space and the sick growth of trees and vegetation, which eventually leads to the death of the trees.

Embodiment Construction

[0051] According to the various chemical raw materials determined by the technical formula of the compound ice-melting and snow-removing agent, the raw materials are tested according to national or industry standards. After passing the test, put various chemical raw materials into the mixer for full mixing. After mixing evenly, put the materials into the pulverizer and pulverize them into 0.5-8mm granules, then put them into the mixer and mix well to form product. The product is tested according to the national or industry standard of "snow melting agent". After passing the test, it is packed in a packaging bag for use. Composite ice-melting and snow-removing agent products should be protected from moisture when stored in the silo. When in use, put them into the ice-melting and snow-removing agent skimming vehicle for skimming or manual spreading, and test their ice-melting and snow-removing effects.

Abstract

The compound ice-melting and snow-removing agent belongs to the category of chemistry and belongs to the technical field of organic and inorganic compound salts. The invention can effectively solve the problems of corrosion of metal and cement concrete and damage to plant growth by the currently used deicing agent in China. It has the characteristics of simple and easy technical scheme, fast melting and snow removal, and good environmental protection performance. The selected chemical raw materials of the present invention and proportioning (weight %) thereof are: calcium chloride (0-90%), urea (5-15%), sodium nitrite (0-10%), sodium metasilicate ( 0-6%), sodium molybdate (0-6%). The present invention is in the form of irregular polygonal natural crystal particles of 0.5-8mm, and is suitable for use in northern cities at temperatures above -33°C. It is mainly used for melting ice and snow on various roads, bridges, squares, parks and street green spaces, especially on various tracks of rail transit, and is suitable for large-scale mechanized throwing operations.

Description
