Abstract
The invention belongs to the technical field of environment, in particular to aN efficient composite anti-corrosive snow melt agent. The snow melt agent has the following main material receipt: 30-70% of w (CaCl2.2H2O), 20-60% of w (MgCl2.6H2O) and 10% of w (chloride); efficient corrosion inhibitor of which the mass concentration is 450mg/L is added to form a corrosion inhibitor of which the substance and mass relation is as follows: m (sodium gluconate): m (zinc dihydric phosphate): m (thiourea) =6:1:2. The snow melt agent of the invention has low freezing point and favorable ice and snow melt effect, has small corrosivity on carbon steel and concrete road surface, has small effect on plant growth, conforms to the relative standard requirements of the snow melt agent and is an efficient environmental-friendly snow melt product capable of replacing sodium chloride and CMA.
Description
Technical field: the invention belongs to the environmental technology field, be specifically related to the anticorrosion Snow Agent of a kind of efficient compound.
Background technology: most of area of China northeast, North China and northwest belongs to the winter snow cover area, and snow can improve environmental quality, helps crop growth, but has also brought inconvenience to daily life simultaneously.Especially Urban traffic.For removing road surface accumulated snow, alleviate the traffic jam problem that snowfall brings, Snow Agent is brought into use in each department.Single sodium-salt type (sodium-chlor), chloride-calcium type research villaumite type, the anticorrosion type to now non-environment-friendly snowmelt agent experienced in the exploitation of Snow Agent.Be characterized in: the composite snow-melting agent that is improved to many components from single composition; Change traditional inorganic Snow Agent, develop organic Snow Agent.For example, the CMA that U.S. DOT company develops, but because its expensive raw material price makes it expensive; On resource, adopt system ester, sugared trade effluent, Pulp industry waste liquid and municipal wastes etc. are accomplished to suit measures to local conditions, and turn waste into wealth.Total target is to seek efficient, pollution-free, no burn into product cheap and easy to get to improve or replace used muriate Snow Agent.Although non-villaumite type Snow Agent is in developing rapidly, because the restriction of economic factors, some developed countries also can only use on a small quantity.China is developing country, the more impossible a large amount of uses in short duration of non-villaumite type Snow Agent.Along with the enhancing of Domestic Environment consciousness, after traditional Snow Agent snow melt on metal, the coagulation and the harm that causes of surrounding plants more and more paid attention to by people.In order to solve the environmental problem of Snow Agent, the development of efficient composite anti-corrosive snow melt agent is extremely urgent.
Summary of the invention: a kind of villaumite that slows down that the objective of the invention is to propose at above-mentioned condition increases the anticorrosion Snow Agent of its efficient compound to the nutrition of plant simultaneously to carbon steel and concrete corrodibility.
The present invention is achieved like this: Snow Agent principal goods material formula: w (CaCl
22H
2O) 30-70%, w (MgCl
26H
2O) 20-60%, w (villaumite) 10%; Adding mass concentration is the 450mg/L high-efficient corrosion inhibitor, forms the material of inhibiter and relationship between quality and be m (Sunmorl N 60S): m (primary zinc phosphate): m (thiocarbamide)=6: 1: 2.
Snow Agent of the present invention is compared with the sodium-chlor corrodibility of same concentrations, to the corrosion of Carbon Steel rate is the 0.91-2.82% of sodium-chlor, to the basic erosion free effect of concrete, and the content of phosphorus also meets China agricultural irrigation water quality standard GB 5084-92, reached environmental protection requirement.
Embodiment: below in conjunction with embodiment the present invention is described in detail,
Embodiment: the prescription of present embodiment is as follows: Snow Agent principal goods material: w (CaCl
22H
2O) 70%, w (MgCl
26H
2O) 20%, w (villaumite) 10%; Adding mass concentration is the 450mg/L high-efficient corrosion inhibitor, and it is m (Sunmorl N 60S): m (primary zinc phosphate): m (thiocarbamide)=6: 1: 2 that the material mass of forming inhibiter is closed.
The prescription of present embodiment is suitable for use in dark cold (30 ℃-35 ℃), the airport that requirement for anticorrosion is higher, bridge floor, motorway.
Snow Agent freezing point of the present invention is low, ice-melt snow is effective, and is little to carbon steel and concrete road surface corrodibility, little to the plant-growth influence, meets the requirement of Snow Agent relevant criterion, is the efficient and environment-friendly type snow melt product that substitutes sodium-chlor and CMA.
