Abstract

The invention discloses casting surface treating fluid and a using method thereof. The surface treating fluid comprises, by weight, 15-18 parts of plating solution, 15-25 parts of a reducing agent, 70-80 parts of adjuvant and 2-4 parts of surfactant. The using method of the surface treating fluid comprises the following steps that the raw materials of the parts are taken and mixed fully to obtainthe surface treating fluid; a casting is placed into a heat energy furnace to be subjected to heat treatment, and then placed into an oil removing groove for oil removing; the casting is sequentiallyplaced into a rust removing groove, a washing groove and an activating groove to be subjected to rust removing, washing and activating, then subjected to cold water treatment and hot water treatment,placed into a plating groove, taken out after being subjected to electrophoresis for 2-5 hours, placed into the washing groove to be washed, and dried. The casting treated through the surface treatingfluid has the beneficial effects that adhesive force is high, the casting does not fall off easily, and the service life is long, and therefore the wear-resistant performance and the corrosion-resistant performance of the casting are enhanced greatly.

Description

technical field [0001] The invention relates to a treatment liquid and its use method, in particular to a casting surface treatment liquid and its use method. Background technique [0002] Castings, such as packaging sealers, are the key and important part of the whole machine, and their surface treatment is especially important. If they are not handled properly, they will produce rust spots, which will seriously affect the use of packaging and sealing equipment. At the same time, with the increasing application of metal materials such as high-strength steel and high-temperature alloys for castings, higher requirements are put forward for their surface treatment technology. At present, the method of electroplating is generally adopted in the market, that is, a protective layer is formed on the surface of the casting to improve the mechanical properties of the casting. However, due to the particularity of the casting material, the plating solution cannot penetrate deeply int...
