Description
Technical Field
The invention belongs to the technical field of coating spraying, and relates to a device for spraying a polymer coating on a solid surface, in particular to a multi-component polymer mixing spiral jet device.
Background
At present, the apparatuses for spraying polymer coatings essentially work in the following way: at least two reactive polymer materials are completely mixed, and the generated mixture is sprayed out linearly in a thin tube form through a nozzle, wherein the mixture is atomized by virtue of pressurized air in the spraying process and then sprayed to the surface of a solid in a coating form. However, the devices of the above-mentioned working modes often have the following disadvantages when in use:
1. the phenomenon of atomization and reflection is easy to occur. The equipment sprays the mixture to the surface of the solid in a linear spraying mode, and the atomized mixture is easy to reflect and splash to other positions after contacting with the surface of the solid, so that the surface of a product finally produced is easy to be dirty, and raw materials are wasted to a certain extent;
2. the solid is easy to move in position during the spraying process. The equipment linearly sprays the mixture in a thin pipe form, the impact force on the surface of the solid is large, if the solid to be coated is thin and has small mass, the position of the solid is easy to move during spraying, the spraying position is changed, the quality of the coating does not reach the standard, and finally the product loss is caused;
3. the spraying is not in place, and the spraying edge is seriously atomized. Firstly, when the sprayed solid is in an irregular shape and the angle between the spraying surface and the spraying straight line is less than 90 degrees, the problem of incomplete spraying is easy to occur, and the mixture is difficult to be sprayed to the non-planar part of the solid comprehensively and uniformly; secondly, the mixture sprayed by the equipment is in a shape of an atomized thin tube, the mixture is in circular distribution when sprayed to the surface of a solid, the distribution of the mixture particles in a spray width is extremely uneven, and the conditions of serious atomization at the circular edge and unclear spraying boundary are easy to occur.
