Abstract
A kind of corrosion inhibiter with protective film, each component and corresponding parts by weight are：10 15 parts of sodium phosphate, 15 parts of chromate, 13 parts of tungstates, 0.5 1 parts of nitrite, 8 10 parts of sodium metasilicate, 10 15 parts of calcium carbonate, 25 parts of titanium dioxide, 25 parts of sodium nitrate, 100 120 parts of water.Corrosion inhibiter used for non-ferrous metal proportioning proposed by the present invention is reasonable, and dosage is few during use, and property is stablized, and environmentally protective, production cost is low.
Description
Technical field
The invention belongs to field of mechanical technique, more particularly to a kind of corrosion inhibiter with protective film.
Background technology
Most metals spontaneous can all chemically react under field conditions (factors) with air or water, its own is then rotten
Erosion, so nature is rarely free of the natural simple metal of other impurities.Metal is good conductor, thus most of metal water,
Under the conditions of electrolyte is existing, easily reacts and go bad or aoxidize or generate other compounds, here it is be not added with protecting
Under conditions of metal erosion the reason of.The harm that metal corrodes is huge, first by the chemical industry facility of metal casting, city
Political affairs pipe network cannot reach due to corrosion expected from service life, increase financial cost；Secondly the main machine made of metal component
Accident occurs for tool, manned tool, pressure vessel etc. or because security intensity is not achieved in metal erosion, increases safety cost；Last gold
The reserves of category are limited, the storage of metal mineral reserves on the consumption earth that uncontrolled corrosion can be too fast, at the same also cost of manufacture,
Technologic waste increases environmental resource protection cost.
Invention content
It is an object of the invention to propose a kind of nontoxic, environmentally protective and at low cost inhibition with protective film
Agent.
The purpose of the present invention is realized using following technical scheme.What is proposed according to the present invention is a kind of with protective film
Corrosion inhibiter, each component and corresponding parts by weight are：10-15 parts of sodium phosphate, 1-5 parts of chromate, 1-3 parts of tungstates, nitrous acid
0.5-1 parts of salt, 8-10 parts of sodium metasilicate, 10-15 parts of calcium carbonate, 2-5 parts of titanium dioxide, 2-5 parts of sodium nitrate, 100-120 parts of water.
A kind of corrosion inhibiter proportioning with protective film proposed by the present invention is reasonable, and dosage is few during use, and property is stablized, and uses
One layer of fine and close oxidation film can be formed to reach corrosion inhibition in the anode region of metal surface, environmentally protective, production cost is low afterwards.
Above description is only the general introduction of technical solution of the present invention, in order to better understand the technological means of the present invention, and
