Abstract
The invention discloses a method for adhering solid particles on the curved surface of a metal workpiece, which comprises the steps of spraying a layer of slowly-volatilized reagent on the metal workpiece with the curved surface by a liquid spray head, spreading the slowly-volatilized reagent to form a uniform adhesion area, spraying the solid particles on the adhesion area by a powder spray head, and adhering the solid particles on the curved surface of the metal workpiece after the slowly-volatilized reagent in the adhesion area is volatilized. The solid particles adhered by the method do not generate physical or chemical changes and have no impurities such as additives and the like, and the second spraying can be carried out by adjusting the spraying amplitude of the liquid spray head and the powder spray head, so that the adhering thickness of the solid particles on the curved surface of the metal workpiece is finally controlled.
Description
Technical Field
The invention belongs to the technical field of surface spraying, and particularly relates to a method for adhering solid particles to a curved surface of a metal workpiece.
Background
A thin film of dust particles is typically deposited on the surface of a rainy ground or on the bonnet of an outdoor parking vehicle, and this naturally deposited film of dust particles is not destroyed by slight shock but falls off by slight wiping due to the forces between the particles and the substrate, particle to particle.
In the test, the solid particles are naturally deposited on the flat substrate by stirring the mixed solution of the solid particles and water or alcohol, thereby obtaining the desired flat adhesion sample of the solid particles.
In order to meet special requirements of tests, solid particles are required to be adhered to the curved surface of the metal workpiece, the adhered solid particles are required not to be subjected to physical or chemical changes, impurities such as additives are not allowed to remain, and the adhered solid particles are uniform and controllable in thickness. There is currently no technical solution available to address this adhesion requirement.
Disclosure of Invention
The invention aims to solve the technical problem of providing a method for adhering solid particles on the curved surface of a metal workpiece.
The invention relates to a method for adhering solid particles on the curved surface of a metal workpiece, which comprises the following steps:
a. spraying a layer of slowly-volatilized reagent on the metal workpiece on the surface of the curved surface by using a liquid spray head, and spreading the slowly-volatilized reagent to form a uniform adhesion area;
b. spraying solid particles on the adhesion area by using a powder spray head;
c. after the slowly volatilized reagent in the adhesion area is volatilized, the solid particles are adhered to the surface of the curved surface;
d. and (c) repeating the steps a to c until the thickness of the solid particles meets the requirement.
The slow volatilization reagent is one of ethylene glycol butyl ether, propylene glycol methyl ether and isoamyl acetate.
The curved surface comprises an inner curved surface or an outer curved surface and is one of a cylindrical surface, a conical surface, a spherical surface and a corrugated surface.
The solid particles are metal particles, solid powder coating or rock particles, the particle size range of the particles is phi 10 um-phi 100um, and the deviation of the particle size distribution of each particle is +/-15%.
The thickness of the solid particles adhered to the curved surface of the metal workpiece is 50-200 um.
The invention relates to a method for adhering solid particles on the curved surface of a metal workpiece, which comprises the steps of firstly spraying a layer of slow volatilization reagent on the curved surface of the metal workpiece, then spraying a layer of solid particles, enabling the solid particles to fall into an adhesion area formed by the slow volatilization reagent, gradually precipitating the solid particles due to the interaction force between the solid particles and the slow volatilization reagent as well as the metal workpiece, gradually adhering the solid particles on the curved surface of the metal workpiece along with the volatilization of the slow volatilization reagent, and finally forming a layer of naturally adhered particle film.
According to the method for adhering the solid particles on the curved surface of the metal workpiece, the adhered solid particles do not have physical or chemical changes, no impurities such as additives and the like are left, the second spraying can be carried out by adjusting the spraying amplitude of the liquid spray head and the powder spray head, and the adhering thickness of the solid particles on the curved surface of the metal workpiece is finally controlled.
