Embodiment Construction

[0032] A coating process for an aluminum alloy tank truck, comprising the following steps:

[0033] 1. Cleaning and degreasing

[0034] 1.1 Clean up the obvious sundries on the surface of the whole vehicle with a rag, etc., without obviously damaging the surface of the tank body and frame;

[0035] 1.2 Before the workpiece enters the coating, check the tank body and the surface of each workpiece. For local oil stains, degrease treatment should be carried out, and the thinner should be applied to the oil stained surface to clean the oil stains. If there is still oil on the surface, clean it again;

[0036] 2. Brushed finish

[0037] 2.1 The surface of aluminum alloy and stainless steel is polished and roughened with sandpaper, and the treatment is as uniform as possible;

[0038] 3. Vehicle cleaning

[0039] 3.1 Use compressed air to carefully blow off the dust on the surface of the workpiece and clean it up;

[0040] 4. Pre-coating of vehicle primer

[0041] 4. 1 Use a ...

Abstract

The invention discloses an aluminum alloy refueling truck coating process. The process includes the following operation steps of 1, cleaning and oil removing: 1.1, using cleaning cloth and the like to clean obvious sundries on the surface of a complete truck without obviously damaging a tank and the surface of a frame; 1.2 before workpieces are coated, checking the tank and the surface of each workpiece, performing ungrease treatment on local oil stains, coating the surfaces of the oil stains with a diluent to wash the oil stains, checking cleaning parts after the surface of the diluent is dried, and cleaning again if the surfaces still have oil stains; and 2, wiredrawing treatment: 2.1 performing polishing and sgraffito treatment on aluminum alloy and stainless steel surfaces with abrasive paper as uniform as possible. The aluminum alloy refueling truck coating process is simple and good in effect, cost is lowered, and quality is guaranteed.

Description

technical field [0001] The invention relates to the field of coating of liquid tank vehicles, in particular to the coating process of aluminum alloy liquid tank vehicles. Background technique [0002] The automobile painting process can generally be divided into two parts: one is the surface treatment of the metal before painting, also called pre-treatment technology; the other is the construction process of painting. Surface treatment mainly includes the removal of oil, dust, rust on the surface of the workpiece, and the removal of the old paint layer during repair work, so as to improve the surface condition of the workpiece. Including mechanical processing and chemical treatment of the workpiece surface according to various specific conditions, such as phosphating, oxidation and passivation treatment. [0003] The existing automobile painting process can no longer meet the actual requirements for the use of modern car bodies, and needs further improvement. Contents of ...
