Glass ceramics are widely used in machinery manufacturing, optics, electronics and microelectronics, aerospace, chemical, industrial, biomedical and construction. Due to the complicated manufacturing process and high technical requirements of the glass ceramic panel, the high-quality glass ceramic production process and control technology are basically monopolized by foreign countries. Therefore, the domestic glass ceramic production process has problems of poor quality and low yield.

Surface cleaning process of high frequency straight seam steel pipe
High-frequency straight seam steel pipes can often become contaminated with oil during the manufacturing process. If these pipes are stored in an open area, they may develop rust over time. To prevent this and maintain their quality, proper cleaning is essential. The first step in the cleaning process is to remove any oil or grease from the surface of the pipe. This can be done through pickling or using a solvent to dissolve the oil. However, the more critical part is effectively removing rust from the steel pipe.
When it comes to rust removal, choosing the right method is crucial. Based on our company's extensive experience, sandblasting (also known as projectile rust removal) is currently considered the most efficient and effective technique. This method involves using a high-speed jet of abrasive materials, such as steel shot or wire brushes, to clean the surface of the pipe. The abrasive particles strike the surface at high velocity, effectively removing rust, scale, and other contaminants until the metal surface reaches a white level—completely clean and ready for further processing or coating.
The effectiveness of sandblasting depends largely on the type of abrasive used and the speed at which it is applied. Different abrasives, such as silica sand, steel grit, or aluminum oxide, offer varying levels of efficiency and suitability depending on the specific application. Choosing the right abrasive not only improves the rust removal process but also helps preserve the integrity of the steel pipe.
In addition to its efficiency, sandblasting is also environmentally friendly when properly managed, as it minimizes the use of harsh chemicals. Overall, sandblasting remains one of the best methods for achieving a clean, rust-free surface on high-frequency straight seam steel pipes.
