Partial Sandblasting Method for Parts

Abstract

The invention discloses a local sandblasting method for a part, which comprises the following steps: step 1: paste a detachable layer on the part that does not need sandblasting; step 2: apply a solidified layer on the outside of the detachable layer; step 3: put Apply the cured layer for natural air drying and curing; after the cured layer is cured, the disassembly layer is in close contact with the parts under the force of the cured layer, and then sandblasting and shot blasting are performed. The strength of the cured layer does not require spraying on the parts. Sand and shot blasting parts are protected; after sand blasting and shot blasting, the disassembly and assembly of the disassembly layer will directly drive the solidified layer to separate from the parts, which solves the problem of using AB glue and other glues on the parts that do not need sandblasting. It takes time and effort to protect and remove the adhesive layer, and it is easy to wear the surface of the part.

Description

technical field [0001] The invention belongs to the technical field of parts surface treatment, and relates to a local sandblasting method for parts. Background technique [0002] After the mechanical processing of the parts is completed, in order to avoid oxidation on the local surface of the parts, it is necessary to spray paint on the parts of the parts. Non-directional dissipation is easy to cause damage to parts that do not need sandblasting; currently, in order to protect parts that do not need sandblasting, glue such as AB glue is applied to the parts that do not need sandblasting, and sandblasting is performed after the glue is cured. This can protect the parts that do not need sandblasting, but when cleaning the cured adhesive layer after sandblasting, due to the strong adhesion between the colloid molecules and the parts, it takes time and effort to remove the adhesive layer, and When removing the adhesive layer, it is easy to wear the surface of the part, affect ...
