 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...

What is PC resistant board? Why do sunroom canopies use it?

First, what is PC board?

Many people have a misunderstanding of PC board, that PC board is acrylic board, is a piece of ordinary plastic board, easy to yellow and become brittle. In fact, PC board and acrylic board is not the same at all! Acrylic sheet is made of methyl methacrylate monomer MMA polymerisation, PC sheet is a high-performance engineering plastics polycarbonate processed. In addition to the two translucency look about the same, the performance of raw materials are not the same, we do not want to get confused.

Second, what are the characteristics of PC sheet?

PC Sheet is a material with excellent light transmission properties, its 6MM thickness of the transmittance of up to 82%, similar to glass, it is difficult to distinguish. In addition, the material also has excellent impact resistance, compared with the same thickness of ordinary glass, plexiglass and toughened glass, its impact resistance is 300 times, 30 times and 20 times higher respectively. Even when a 3kg hammer is dropped from a height of 2 metres, the material remains undamaged. As a result, sunrooms and canopies made of PC panels can effectively withstand damage from hail, snow pressure, and overhead smashers.

In addition, the heat transfer coefficient of PC sheet is 1.1-4.1W/m2℃, which is lower than the heat transfer coefficient (K value) of ordinary glass and other plastics, and its heat insulation effect is 7%-25% higher than that of the equivalent glass, and its heat insulation performance can be up to 49%. In the outdoor application of sunroom and canopy, even in the sun exposure, the material will not turn yellow and decay, ten years after the loss of light transmission rate of only 6%.

Third, the PC endurance plate application cases 

With the development of materials, PC endurance plate in the field of construction is very widely used in the domestic field, can be used for patio awnings, courtyard sunroom, terrace sunroom, etc., can also be used in the field of outdoor canopies such as stations, airports, etc., can effectively prevent ultraviolet rays, so can be used for a long time in the outdoors.

 

The application of PC endurance board in various fields is very wide, with good performance and use effect. In the future, the application fields of PC resistance plate will continue to expand and deepen.

What is a coal bunker?

-
图片
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 ...
