Description
Technical field
The invention belongs to detergent technical fields, and in particular to a kind of degreaser and preparation method thereof for galvanized sheet.
Background technology
Galvanized steel plain sheet is widely used in the industries such as building, electromechanics, household electrical appliances, and steel plate needs progress oil removing clear after zinc-plated
It washes, traditional forms of enterprises's cleaning galvanized steel plain sheet generally uses trichloro ethylene, but trichloro ethylene one side is not environmentally, on the other hand may
Stamping forming notch is caused to get rusty.Ye You enterprises are cleaned using degreasing powder, deoil although general degreasing powder can remove
Dirt, but since its alkalinity is excessively high, zinc coat can be hurt.
CN107313060A discloses a kind of Al-Zn coated steel degreaser, which includes sodium carbonate, piece alkali, anion
Surfactant, antifoaming agent, poly-aspartate, polyacrylic acid, complexing agent and water, the degreaser which provides, can be in material
Material surface forms fine and close protective layer, overcomes the problem that aluminum-zinc alloy material surface is easily corroded, can be effectively prevented material
The phenomenon that surface generates mildew because of galvanic corrosion or air oxidation, while also there is good deoiling effect, to environment dirt
Contaminate it is small, with skin contact fanout free region.CN103572305A discloses a kind of oil removing that steel surface can be removed under normal temperature condition
Agent, by phosphate, carbonate, pyrophosphate, disodium ethylene diamine tetraacetate, alkyl diethanolamide, fatty alcohol polyoxyethylene ether,
Polyethers and higher alcohol are constituted, and the formula of the invention, deoiling effect is apparent, and the antirust of steel surface can be removed under normal temperature condition
Oil.
Oil removing is to rely on cleaning agent to the dissolving of greasy dirt, saponification and SURFACTANT ADSORPTION, wetting, infiltration and divide
The effects that scattered, makes the process that greasy dirt and metal interface detach.Existing degreaser residue after oil removing is not easy to rinse, especially
It is the residual between blind hole, gap, if dried not in time, is easy to happen corrosion, and many problems can be also caused to following process.
Therefore, it is necessary to develop a kind of new degreaser, noresidue or residue are easy to rinse well after oil removing.
