 Corrosion Protection Process for Steel Structures Corrosion protection processes for steel structures are essential for ensuring that steel structures remain in good condition over the long term. This article provides a detailed overview of the various steps involved in these processes, including surface preparation, priming, coating application, quality control, and final inspection and acceptance. Surface treatment Surface preparation is the first step in the corrosion protection process. Its primary purpose is to remove dirt, grease, rust, and other contaminants from the surface of steel structures to improve coating adhesion and corrosion protection. Surface preparation includes the following steps: Cleaning: Removing grease, dirt, and dust from the surface of steel structures using solvents or detergents. Degreasing: Removing grease and wax-like substances with an alkaline degreaser to improve coating adhesion. Rust Removal: Removing rust and other corrosion products from the...

 Introduction to the performance of various core materials of colour steel composite panels



(1) Foam board

From the optional polystyrene (EPS) particles as raw materials, shape like fertilizer particles, pre-foaming by heating, into a white pearl-like larger particles, and then heated in the mold and pressed into shape and made with micro-fine closed-cell structure of the foam plastic sheet.

(2) Polyurethane High energy-saving performance

Excellent fireproof and thermal insulation properties of the material, used to do composite panels of polyurethane capacity of 30 kg - 40 kg in general

(3) Rock wool board

It is made of basalt as the main raw material, melted at high temperature and then made into inorganic fibres by high-speed centrifugal equipment, while evenly adding a certain proportion of adhesive baked into a large board, cut into rock wool strips according to production needs, rock wool is a non-combustible body with good fire performance.

(4) Glass wool

It is a light, heat-resistant, elastic and otherwise thermal insulation material, widely used in chemical, pharmaceutical, factories, heavy industrial machinery and equipment, construction, vehicles and ships, aerospace, and is an ideal material for heat breaking, fire prevention and sound absorption.

(5) Flame retardant paper honeycomb board

For the national B1 level fireproof material, has the advantages of good flame retardancy, good compressive strength, only carbonization not burning, no toxic substances, waste can be completely recycled, etc., is the ideal substitute for polystyrene, polyurethane, rock wool and other core materials.

What is a coal bunker?

-

Coal bunker , is a structure used for storing coal. Coal bunkers play an important role in thermal power plants, coal mines and coal marshalling stations. Depending on the specific application scenario and design, there are various types of coal bunkers, such as circular coal bunkers, square coal bunkers and open coal yards. Safety Management of coal bunkers Preventing spontaneous combustion of coal: Since coal itself contains certain moisture and volatile substances, long-term exposure to the air may lead to spontaneous combustion, so the safe management of coal bunkers is of great significance in preventing spontaneous combustion of coal. Ensure the quality of coal: coal in the coal bunker usually needs to be stored for a long time, if not managed properly, it may lead to the decline in the quality of coal, such as sulphurisation, weathering and other phenomena, so it is necessary to ensure the quality of coal by strengthening the safety management of the coal bunker. Improve the eco...

What is the difference between a single-layer reticulated shell and a double-layerreticulated shell?

  The differences between single-layer reticulated shells and double-layer reticulated shells are as follows: Structural Configuration   Single-layer reticulated shell: Composed of a single layer of members, with the members directly connected to form a grid structure . The node configuration is relatively simple, typically employing rigid connections that allow the members to bear not only axial forces but also bending moments and shear forces.   Double-layer reticulated shell: Consists of upper and lower parallel layers of members connected by web members, forming a truss-like structural system. The nodes are generally hinged, and the members primarily bear axial forces. Its configuration is relatively complex, requiring more members and nodes to ensure structural stability and load-bearing capacity. Structure Single-layer mesh shell: composed of one layer of rods, the rods are directly connected to form a mesh structure, the node structure is relatively simple, usually...

What are the differences between bolted ball grids and welded ball grids?

图片
 There are a number of differences between bolted ball grids and welded ball grids in terms of fabrication, construction and design. The following are specific comparisons: 1. Manufacturing process: The manufacturing of bolted ball net frame is mainly carried out in the factory, using mechanical shot blasting to remove rust, and then spraying paint, plastic spraying or zinc spraying treatment to enhance corrosion resistance.  The steel pipe and welded seam of welded ball mesh frame can only be descaled manually on site, and then paint or fireproof coating is brushed. For the welded part, it needs to be descaled and brushed at a stage to maintain, which increases the cost of later use and affects the safety of the structure. 2. Construction process: 70% of the workload of bolted ball grid frame is prefabricated in the factory, 30% of the workload is installed at the site, only a wrench is needed to tighten the bolts at the site, which is easy and fast, and can be constructed ...
