[0004] 2. Not environmentally friendly
Zinc belongs to the heavy metal category. In the hot-dip galvanizing production process, a large amount of acid mist and zinc ion discharge will be generated in the pre-treatment process, and a large amount of zinc dust will be generated in the galvanizing process. Although the production enterprises have adopted environmental protection measures, there is still some acid mist 1. Zinc flows into the environment, causing environmental pollution; moreover, during the use of zinc products, zinc is continuously dissolved into the environment through the corrosion of rainwater, causing environmental pollution
[0005] 3. More labor
Most of the current hot-dip galvanizing enterprises are not highly mechanized, and most of the galvanizing is produced manually
However, the production process of hot-dip galvanized + polyethylene coating, hot-dip galvanized + po

Example Embodiment

[0034] Example 1, such as figure 1 As shown, an epoxy zinc-based polyester composite coating road steel guardrail production line includes a corrugated board production equipment and a column production equipment.

[0035] The corrugated plate production equipment mainly includes the corrugated plate cold-formed module, the corrugated plate shot blasting processing module, the corrugated plate chemical processing module, the corrugated plate automatic loading module, the corrugated plate double-layer spraying module, the corrugated plate automatic loading and packaging module, each Automatic connection between modules without manual work.

[0036] Such as figure 2 As shown, the corrugated plate is difficult to shot blasting due to its complex shape. The corrugated plate shot blasting processing module adopts a specific blasting head arrangement. There are two groups of blasting heads, one set for the upper and lower blasting heads. Perform shot blasting on the front of the corruga...

Example Embodiment

[0040] Embodiment 2 is the production process of the epoxy zinc-based polyester composite coating road steel guardrail. The production process includes the preparation process of the corrugated board and the preparation process of the column.

[0041] The preparation process of the corrugated board includes: strip steel feeding → cold bending forming → shot blasting treatment → dust removal → automatic loading → chemical pretreatment → drying → spraying primer → curing → spraying flour → curing → automatic loading → Automatic inspection → automatic packaging.

[0042] The preparation process of the column includes: strip steel feeding → shot blasting → dust removal → forming welding → automatic loading → chemical pretreatment → spraying base powder → curing → spraying flour → curing → automatic loading → automatic inspection → automatic packaging.

[0043] In the preparation process of the column, the process of forming and welding steps is anti-rust. In this embodiment, the environm...

Abstract

The invention relates to a production line and process of a steel road barrier with an epoxy zinc-based polyester composite coating. The production line of the road barrier is a fully-automatic production line, the production line has the advantages of stable product quality, small labor amount and high efficiency in the process from strip steel loading to one-step finishing of product molding; the produced steel road barrier adopts a double-layer anticorrosive structure including a zinc-based epoxy coating and a polyester coating to replace the traditional hot galvanizing, hot galvanizing and polyester hot-dipping as well as hot galvanizing and polyethylene hot-dipping technologies, so that a product is stable in quality, good in anticorrosion, long in service life and capable of meeting the requirements for coating uniformity and range as well as coating anticorrosion, the coating range does not exceed 40mu m, and the service life of the coating is also prolonged by more than 20% than that of a conventional product; in addition, the production process of the steel road barrier is environment-friendly and pollution-free, and the curing temperature of the coating is only 200 DEG C, while the hot galvanizing temperature is 450 DEG C, so that energy is saved, and the loss of the produced heat energy is reduced by more than 60%.

Description

Technical field [0001] The invention relates to a highway steel guardrail and a preparation process thereof. It is suitable for double anticorrosive highway steel guardrails, especially suitable for highway steel guardrails with epoxy zinc-based polyester composite coating. Specifically, the invention relates to an epoxy zinc Production line and production process for highway steel guardrail based on polyester composite coating. Background technique [0002] At present, domestic and international highway steel guardrails mainly include three product types: hot-dip galvanizing, hot-dip galvanizing + polyester coating, and hot-dip galvanizing + polyethylene coating. These product types have some defects, as follows: [0003] 1. High energy consumption. The temperature of the hot-dip galvanizing process is generally around 450°C, and the production of galvanizing requires high heat energy. Moreover, the higher the production temperature, the lower the effective utilization rate of h...
