AI Technical Summary

Problems solved by technology

On the one hand, the welding process is complicated to operate and has high requirements on materials. On the other hand, the sprayed paint is an organic material, which pollutes the environment, and the paint itself cannot play a flame-retardant effect and has low hardness.

Embodiment 1

[0032] The ceramic coating is a composite ceramic coating of metal and ceramics. The composite ceramic coating contains the following components in mass fractions: 20% magnesium oxide, 40% aluminum oxide, 10% nickel, 5% chromium, 10% boron, iron 15%.

[0033] A process for preparing train wallboards, comprising the steps of:

[0034] Pretreatment: Set the pressure of the press and jacking cylinder, place the profile on the drawing die table, and apply lubricating oil on the surface of the profile, and perform stretching treatment. The pre-stretching treatment can eliminate the residual stress inside the profile. Ensure the uniformity of stretching of the profile;

[0035] Stretching: the stretching operation is completed, and the stretching height is controlled at 20mm each time during the stretching process until the stretching reaches the desired height;

[0036] Surface treatment: After the stretching treatment, carry out edge trimming and edge cutting operations to obtai...

Abstract

The invention discloses a train wallboard. The train wallboard comprises a wallboard body, a window is formed in the wallboard body, installing grooves are formed in the periphery of the window, and sealing strips are fixed in the installing grooves; reinforcing bases are symmetrically arranged on the two sides of the window, the multiple reinforcing bases are arranged on the same side of the window, the adjacent reinforcing bases are fixed through reinforcing ribs, and a ceramic coating is arranged on the surface of the wallboard body. The invention relates to a manufacturing technical method of the wallboard, the manufactured wallboard is high in rigidity and environmentally friendly and has a flame retardant effect, and no harmful substance is generated in the preparation process and the manufacturing process. A stretching forming technology is adopted, so that combination and seal performance of the wallboard are ensured.

Description

technical field [0001] The invention relates to a train wallboard, in particular to a high-speed train or subway wallboard processing technology. Background technique [0002] A train, many continuous vehicles, generally refers to a train, especially a connected train consisting of traction locomotives and carriages for transporting goods or carrying passengers. Trains are divided into passenger trains for transporting passengers, freight trains for transporting goods, mixed passenger and freight trains for both passenger and freight, and trains with specific functions for military and rescue purposes. [0003] Underground railway: referred to as the subway, also referred to as the subway. In a narrow sense, it specifically refers to the urban rail transit system that mainly runs underground. But in a broad sense, since many of these systems may also have surface road sections in order to match the built environment, it usually covers various underground and above-ground h...
