Problems solved by technology

[0002] Polyurethane boards generally have a multi-layer structure, and the surface of each layer needs to be sprayed with paint. If it is sprayed manually, it cannot guarantee uniform spraying, and it is time-consuming and laborious. Therefore, mechanical equipment is usually used to drive the discharge gun barrel for spraying. However, existing Most of the discharge gun barrels are made of metal tubes by punching holes, which are not only easy to block, but also need to be replaced frequently, which directly increases the spraying cost; and because the inner diameter of the discharge gun barrel is small, direct processing of its inner surface has certain limitation

Abstract

The invention provides an anti-blockage treatment method for a discharge gun barrel. The method comprises manufacturing of an anti-blockage layer and recombination of the anti-blockage layer; and the anti-blockage layer is molded with the inner wall of the discharge gun barrel through an anisobaric casting method. According to the method, an existing discharge gun barrel can be directly utilized and transformed, so that the treatment cost is lowered. A limited space in the discharge gun barrel is treated through the anisobaric casting technological method to enable the anti-blockage layer and the inner wall of the discharge gun barrel to be molded. The problem of difficult treatment caused by a small space is solved. The lubricity and smoothness of the manufactured anti-blockage layer are high, coating flowing in the discharge gun barrel is facilitated, and the problem of easy blockage is effectively solved.

Description

technical field [0001] The invention belongs to the technical field of polyurethane board processing, and in particular relates to a treatment method for preventing blockage of a discharge gun barrel used for paint during polyurethane board processing. Background technique [0002] Polyurethane boards generally have a multi-layer structure, and the surface of each layer needs to be sprayed with paint. If it is sprayed manually, it cannot guarantee uniform spraying, and it is time-consuming and laborious. Therefore, mechanical equipment is usually used to drive the discharge gun barrel for spraying. However, existing Most of the discharge gun barrels are made of metal tubes by punching holes, which are not only easy to block, but also need to be replaced frequently, which directly increases the spraying cost; and because the inner diameter of the discharge gun barrel is small, direct processing of its inner surface has certain limitation. [0003] Therefore, it is an urgent ...
