Anti-corrosion treatment process of components of assembling iron art guardrail product

Abstract

The invention relates to an anti-corrosion treatment process of components of an assembling iron art guardrail product. The anti-corrosion treatment process comprises the following process steps thataccording to the design requirements and the assembling structure design requirement of the guardrail product style, sectional materials are selected to carry out corresponding punching, drilling andother deep processing to be then welded to form square steel pipes and assembling connecting components, and deburring treatment and removing welding trace treatment are carried out on the deep processing parts of pipes and assembling connecting parts; then overall hot-dip galvanizing anti-corrosion treatment on the pipes and the assembling connection components are performed, and then the components are subjected to paint coating and powder coating of the single-layer powder coating which comprise primer coating, middle coating and the surface coating; the powder coating is selected to be sent into a drying room to be heated at the temperature of 180-200 DEG C; and finally, protective packaging is carrying out on pipes and assembling connecting components so as to obtain the assembling iron art guardrail product. The iron art guardrail product produced by adopting the anti-corrosion treatment process has excellent corrosion resistance, and has the advantages of being good in weather resistance, long in service life for 50 years, and excellent in quality and the like.

Description

technical field [0001] The invention relates to a production process of wrought iron guardrail products. Background technique [0002] Wrought iron guardrail products are wrought iron components used to isolate and shield specific spaces, interfaces, and objects, and at the same time play a certain ornamental effect. It can be roughly divided into balcony iron railings, wall decorations and garden iron railings, road iron art railings, window decoration iron art railings, escalator iron art railings and other alternative iron art railings. In principle, no matter any of the above-mentioned different types of wrought iron guardrail products, it should reflect the unity of its functionality, weather resistance, and aesthetics; it should have the convenience and environmental protection of the construction process; safety in the process. However, a large number of facts in reality prove that it is far from easy to realize the above-mentioned basic requirements. A large numbe...

Problems solved by technology

A large number of wrought iron guardrail products produced according to the traditional design and manufacturing process have the following obvious deficiencies: (1) ignore the crevice corrosion that may occur during the service of the guardrail products and the manufacturing and construction factors that cause the inner wall to corrode first; (2) the current The traditional process commonly used in the whole industry is to directly select galvanized sheets and galvanized pipes for welding and grinding, and then paint the surface and sell them directly as finished products

This kind of production process will directly destroy the integrity of the zinc coating of galvanized pipes and galvanized sheets, and the corrosion resistance of wrought iron guardrails will be greatly weakened; Poor coating performance, not weather-resistant, not durable, and not beautiful; (4) Due to improper design and craftsmanship, most guardrail products can only be formed at the production site, and then transported to the construction site for installation, and the welding, repairing Grinding and other steps will directly destroy the zinc layer of the guardrail, and cannot form a complete isolation layer. The work efficiency is low, the cost rises, the construction quality is unstable, disturbing the people and not environmentally friendly, and it is easy to cause premature failure of the guardrail products, and even lead to safety accidents
