The sandblasting room is applied to steel structures
In steel structure factories, the core function of the sandblasting room is to perform surface pre-treatment for large steel structures (such as bridge components, building frames, heavy machinery chassis, etc.) before coating. It uses high-speed jetting of abrasive materials to thoroughly remove rust, oxide scale, welding slag, and oil stains on the surface of the workpieces, achieving a clean surface while also forming a certain degree of roughness. This significantly improves the adhesion of the subsequent coating and realizes long-term corrosion prevention.
Compared to traditional open-air sandblasting or manual cleaning, the advantages of the sandblasting room in steel structure factories are very prominent and can be summarized as the following four points:
A. Efficiency and Automation: Solving the problem of handling "large-sized items"
Steel structures usually have the characteristics of large size, irregular shape, and heavy weight. The sandblasting room is specifically designed to solve these problems.
B. Multi-gun Combined Operation: Using fixed sandblasting devices and servo sandblasting devices to work together, achieving simultaneous operation of two or more guns.
C. Significantly increase rust removal efficiency, transforming the comprehensive rust removal of heavy steel structures from a "protracted battle" to a "lightning strike".
Intelligent Control: Equipped with PLC (Programmable Logic Controller) and touch screens, it can precisely preset parameters such as sandblasting pressure and abrasive flow rate, and achieve one-click start and stop and automatic alarm, reducing reliance on manual experience and ensuring consistent processing results.
Flexible Adaptability: The size of the sandblasting room can be customized non-standardly according to the size of the workpieces, and the maximum size can reach up to 10 meters or more. At the same time, it can be combined with track transportation vehicles or hanging systems to achieve rapid entry and exit of workpieces and circulation.
D. Green and Environmental: Building a new benchmark for "dust-free workshop"
Environmental protection is a hard requirement for current industrial production. The sandblasting room has completely changed the traditional image of "dust flying everywhere" in sandblasting operations through a closed design and efficient dust collection system.
Closed Operation and Efficient Dust Collection: The entire sandblasting process is carried out in a closed room, preventing dust from spilling out at the source. The configured pulse bag dust collector or filter cartridge dust collector has a dust removal efficiency of over 99%, ensuring that the emitted gas meets or even exceeds national environmental protection standards.
Automatic Sandblasting Material Recovery and Recycling: Through a scraper-type sand recovery mechanism, using the principle of cylinder transmission, the sand sprayed out and the generated dust are recovered together, and the intact sand is separated by the sorting system for recycling, while the waste is sent to the dust collector. This not only increases the sand recovery rate to over 95%, significantly reducing material costs, but also realizes a new construction environment of "dust-free workshop + healthy operation", with the scraper-type sand recovery system having the advantages of a small pit, low energy consumption, and low maintenance costs.
Economic and Intelligent: Reducing overall costs and improving management accuracy
Modern sandblasting rooms not only focus on performance but also fully consider the long-term operational costs and convenience of enterprises.
Reducing Infrastructure and Maintenance Costs: Sandblasting rooms using scraper recovery technology do not need to dig deep pits like traditional mechanical recovery types, significantly shortening the construction period and reducing construction costs, especially suitable for the renovation of old factories. At the same time, as it reduces the use of a large number of mechanical transmission components such as spiral conveyors and belt conveyors, the annual maintenance cost of the equipment can also be significantly reduced.
Parametric and Intelligent Management: The intelligent control system is not only easy to operate but also can monitor the sandstock, dust concentration, and equipment status in real time, making the production process transparent and controllable, facilitating enterprise precise management.
The effect after treatment has clear quantitative standards. After sandblasting and rust removal of steel structures, the surface cleanliness usually reaches the industrial standard of Sa2.5-Sa3 (i.e., a very thorough rust removal level), and the surface roughness can also meet the requirements for high adhesion coating in the future.
Have you mainly come into contact with large steel structures like bridges, or conventional-sized components like factory frames? These two types of workpieces have a significant impact on the size of the sandblasting room and the selection of the recovery system.
