Problems solved by technology

Especially in winter, the winter in the north is colder, and the coldest place can reach more than minus 30 degrees. Many materials containing water will freeze and stick to the wall of the container in winter, making it impossible to re-transport
The extreme weather in winter brings great inconvenience to the storage, transportation and unloading of materials
For example: when coal is transported to stockyards, stations, and wharves in winter, the water-containing coal freezes and sticks to the inner wall of ordinary storage compartments, and cannot be unloaded normally. It must be crushed by a crusher before unloading. The structure has been damaged to a certain extent; in addition, when the slag is excavated in the north in winter, it is very easy for the rare slag to condense rapidly in the storage bin and dump truck, resulting in the abnormal transfer of the slag

Embodiment 1

[0015] Embodiment 1: a kind of anti-sticking high-strength engineering equipment container processing method, comprises the following steps:

[0016] (1) Surface treatment of the inner surface of the container: First, apply an organic solvent to dissolve the oil on the inner wall of the container and heat it to 400°C, so that all the oil on the inner wall of the container is completely volatilized, and then use sandblasting to mechanically clean the container and make the inner wall rough. Use the nature of organic solvents to dissolve grease to remove oil stains, and use sandblasting to improve the solidification effect of the mixed material on the inner wall of the container after spraying.

[0017] (2) Mixed coating spraying: After mixing high-carbon fiber precursors and paraldehyde according to a certain mass ratio, spray them directly on the inner wall of the container, and then spray polytetrafluoroethylene, paraldehyde and polytetrafluoroethylene The mass ratio is 1:20,...

Embodiment 2

[0020] Embodiment 2: a kind of anti-sticking high-strength engineering equipment container processing method, comprises the following steps:

[0021] (1) The inner surface treatment of the container is the same as in Example 1.

[0022] (2) Mixed coating spraying: After attaching the high-carbon fiber with a network structure on the inner wall of the container, spray paraldehyde first, and then spray polytetrafluoroethylene. The mass ratio of paraldehyde to polytetrafluoroethylene is 1:19, high carbon fiber raw silk can adjust the mixing ratio according to actual needs. The spray coating material must be uniform, and the coating thickness depends on the coating system used. The spraying amount of PTFE is determined according to the coating thickness, and the coating thickness varies from a few microns to 200 microns (0.2 mm). .

[0023] (3) drying, the same as in Example 1.

[0024] (4) Sintering is the same as in Example 1.

[0025] It must be emphasized that the mass rat...

Abstract

The invention discloses a method for treating an anti-bonding high strength engineering equipment container. The method comprises the steps that the inner surface of the container is treated; a mixed coating is sprayed; high carbon fiber precursor and paraldehyde are mixed according to an actual demand ratio and then are directly sprayed to be attached to the inner wall of the container, and afterwards teflon is sprayed; or after high carbon fibers of a net-shaped structure are attached to the inner wall of the container, paraldehyde is sprayed first, then teflon is sprayed, the mass ratio of the paraldehyde to the teflon is no more than one to nineteen, the mixing ratio of the high carbon fiber precursor can be adjusted according to actual needs, drying is performed, and sintering is carried out. By the adoption of the treating method, materials containing water can be prevented from being bonded on the wall of the container because of low temperatures, the materials can be normally transferred and unloaded secondarily, and the impact strength of the container is improved.

Description

technical field [0001] The invention relates to a processing method for an engineering equipment container. The container is suitable for storing, transporting and unloading materials during construction in winter, and has the functions of anti-freezing and anti-sticking. Background technique [0002] my country has a vast territory, and the climate between the north and the south is significantly different. Especially in winter, the winter in the north is colder, and the coldest place can reach more than minus 30 degrees. Many materials containing water will freeze and stick to the container wall in winter, making it impossible to re-transport. The extreme weather in winter brings great inconvenience to the storage, transportation and unloading of materials. For example: when coal is transported to stockyards, stations, and wharves in winter, the water-containing coal freezes and sticks to the inner wall of ordinary storage compartments, and cannot be unloaded normally. It...
