Abstract

The invention discloses a rust removing method for steel plates. The rust removing method specifically comprises the following steps that 1), a rust removing agent is prepared, and the rust removing agent is prepared by uniformly mixing the following components in parts by mass: 150-200 parts of sulfuric acid, 55-75 parts of phosphoric acid, 200-300 parts of hydrochloric acid, 15-35 parts of urotropine and 10-30 parts of distilled water; 2), the rust removing agent is poured into a high-pressure spraying machine spraying can; 3) the steel plates are placed orderly; 4), the rust removing agentis uniformly sprayed on the surface of each steel plate by using a high-pressure spraying machine, and then the steel plate is overturned so that the rust removing agent is sprayed on the other side;5), the steel plate on which the rust removing agent is sprayed is dried; and 6) the steel plates are conveyed indoors for storage. The rust removing method provided by the invention is simple and easy to implement; surface rust stains can be rapidly and effectively removed; no corrosion is generated to utensils; the raw materials are simple; and cost is low.

Description

technical field [0001] The invention relates to a method for derusting a steel plate, which belongs to the technical field of mechanical device processing. Background technique [0002] The problem of steel rusting seems to be a common problem in the steel field, especially in the pharmaceutical, medical equipment and related industries, which have stricter requirements for steel rust removal. Metal rust removers remove rust, contaminants (carbon deposits), oxides. The metal surface treated by it will not affect welding, electroplating and painting. After rust removal, the original color of the metal is maintained, and it is non-corrosive to the human body. At present, the common derusting methods on the market include artificial angle grinder grinding and derusting, steel derusting machine derusting, sandblasting machine shot blasting machine derusting and steel derusting agent derusting several methods, which are not suitable for a large number of derusting work , the c...
