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 composite ice-melting snow removal agent, the raw materials are tested in accordance with national or industry standards. After passing the test, put all kinds of chemical raw materials into the mixer for full mixing. After stirring evenly, put the materials into the pulverizer and pulverize them into 0.5-8mm particles, and then put them in the mixer and mix them evenly to form product. The products are tested in accordance with the national or industry standards of the "snow-melting agent". After the test is qualified, the products are packed in packaging bags for use. For composite ice-melting and snow removal products, please pay attention to moisture-proof when stored in the silo. When using it, put it into the ice-melting and snow-removing agent spreader for spreading operation or manual spreading, and test its ice melting and snow removal effect.

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 their proportioning (weight %) are: magnesium chloride (0-90%), urea (5-15%), sodium nitrite (0-10%), sodium metasilicate (0-90%) 6%), sodium aluminate (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

[0001] The composite ice-melting and snow-removing agent has significant ice-melting and snow-removing effects, is widely applicable, and has the characteristics of novelty, creativity and practicality, and meets environmental protection requirements. The specific content is now explained as follows: 1. Technical field [0002] It belongs to the category of surface chemistry, and belongs to the technical field of organic and inorganic composite salts. 2. Background technology [0003] 1. Understanding of the invention of "composite ice-melting snow remover" [0004] (1) The composite ice-melting and snow-removing agents and the currently used snow-melting agents, whether in solid or liquid state, are all for reducing the freezing point of water. The snow melting mechanism belongs to the category of surface chemistry, which is the technical field of organic and inorganic composite salts. It utilizes the water absorption of the composite ice-melting and snow-removing agent and the l...
