How to improve the corrosion resistance of glass greenhouses?

Due to the rapid development of modern facilities and automated operating systems, glass greenhouses have been widely used. But many people still don't know how to improve the corrosion resistance of the equipment. The editor of this issue will share with you how to improve its corrosion performance.

1. The durability of the greenhouse is affected by the anti-aging ability of the greenhouse itself and the carrying capacity of the main structure of the greenhouse. Of course, the durability of the optical transmission data of the glass greenhouse shows that the optical transmission rate of the data decreases with time. The attenuation of the optical transmission rate is a decisive factor affecting the service life of the optical transmission data. Generally, the service life of the steel structure greenhouse is more than 15 years. The planned wind and snow load is a heavy load that occurs once in 25 years. The bamboo-wood structure simple greenhouse has a service life of 5-10 years, and the planned wind and snow load is a heavy load that occurs once in 15 years.

2. In the construction of the glass greenhouse, due to the long-term indoor high temperature and high humidity environment, the external anticorrosion of the components has become one of the important factors affecting the service life of the greenhouse.

3. Steel structure greenhouses generally use thin-walled steel as the main stress structure, which has poor corrosion resistance. In the greenhouse, hot-dip galvanizing is required for external corrosion protection. The coating thickness reaches 150-200 microns, which can guarantee a 15-year service life. For greenhouses with wood structure or steel welded truss structure, it is necessary to ensure that anti-corrosion treatment is carried out once a year.

4. Common rusty parts in glass greenhouses include:

1. The welding part of the main components.

2. Auxiliary parts such as insulation strips, simple doors, etc., the cut surface and end surface galvanized layer is relatively thin, easy to rust.

3. The internal equipment of the greenhouse, such as flower beds, turntables, columns, etc. Due to the high humidity and temperature of the air in the greenhouse, the weak zinc layer and welding parts are more likely to corrode.
