Spraying cleaning agent for die-casting aluminum shell

Abstract

The invention discloses a spraying cleaning agent for a die-casting aluminum shell, which is applied under ultrahigh pressure. The spraying cleaning agent comprises the following components by weightpercent: 5% of sodium citrate, 10% of 3-methoxyl-3-methyl-butanol, 5% of an aluminum corrosion inhibitor, 3% of ethanol, 10% of polyethylene glycol, 2% of sodium hydroxide, 2% of sodium nitrate, 2% ofsodium molybdate, 4% of sodium thiosulfate, 5% of aluminium chloride, 1% of titanium dioxide, 2% of silicon dioxide, 1% of anbydrous borax and 1% of an antifoaming agent, and the balance being water.When the cleaning agent is utilized to remove burrs at 20 DEG C to 40 DEG C and at spraying pressure of 2 MPa to 15 MPa, a low-foam and non-foam state can be still maintained, and the residue degreeafter cleaning is low.

Description

technical field [0001] The invention relates to a metal spray cleaning agent, in particular to a spray cleaning agent applied to a die-casting aluminum shell under ultra-high pressure. Background technique [0002] As an important core component of the automobile powertrain, the gearbox has very high processing technology content, equipment level and quality requirements. Its excellent product performance is a key factor that reflects the core competitive advantage of the complete vehicle enterprise. The core parts of the gearbox mainly include shafts, gears and housings. The parts must be strictly cleaned before assembly to remove metal shavings, dust, cutting fluid, grease and other pollutants on the surface. Among them, the shell is usually made of die-cast aluminum. Due to the active chemical properties of aluminum, the requirements for cleaning effect are more complicated than those of ferrous metals. Not only the cleanliness after cleaning is required to meet the stand...
