Based on a comprehensive study of the current status of electrolyzer life in China and its major influencing factors, the project proposes research directions and corresponding technical measures to eliminate early damage, maintain stable mid-term operation, and strengthen monitoring of late-stage three-system key technologies.
The technical innovations of this project are as follows:
1. The use of a large-size boron-titanium composite layer to wet the cathode, a graphite cathode with a graphite content of more than 30%, and a silicon nitride-bonded silicon carbide-carbon composite side-block series can improve the stability of the operation of the electrolytic cell. Sex, reduces the bottom pressure drop.
2. The optimization and popularization of coke roasting start-up technology will help improve the service life of the tank.
3. Researched and proposed different types of electrolytic tank lining material systems, providing the basis for optimizing the structural design of the electrolytic tank.
The project will integrate the research of new technologies, new processes, and new materials into system research. As a whole, it conducts industrial tests and popularization and application on some different types of large prebaked cells of China Aluminum Corporation. Through the implementation of this project, the average life of the electrolytic cell of Chinalco was increased by 300 days, and the benefit created was 56.07 million yuan.
At present, China's electrolytic aluminum industry is in the period of industrial restructuring. This project provides an indispensable technology for aluminum industry in China to increase the service life of aluminum electrolytic cells, and promotes the overall technical level of China's electrolytic aluminum industry to enter the world's advanced ranks, resulting in significant The economic and social benefits.
Drop-in kitchen sinks, also called self-rimming sinks, overmount sinks, or top-mount sinks, are sink basins that install and sit on top of your kitchen counter. There is a visible rim or lip on the perimeter of the basin that rests just over the cut-out for the sink. Drop-in sinks are supported by this lip and a series of hidden clips that attach to the underside of the countertop.
The Advantages of Drop-In Sinks
Drop-in sinks have some clear advantages over other styles, especially in the kitchen.
Cost
They`re generally cheaper to buy and easier to install than undermount sinks. In fact, even weekend warriors and DIY newbies should have no problem installing a basic overmount sink. If cost is a consideration in your kitchen, an overmount sink with a do-it-yourself install is a great way to stay within budget.
Cleaning
While cleaning may not be your foremost concern when choosing a kitchen sink, it should be considered. After all, you`ll have to care for and maintain your sink regularly. The basin of an overmount sink is easier to clean than the basin of an Undermount Sink.
Protection
If you`ve got soft countertops, drop-in sinks can help protect the edges of the sink cutout.
- Marble and some specialty counter finishes benefit from the added protection provided by the lip of a drop-in kitchen sink basin. It prevents the build up of water on the surface edges of the stone through repeated exposure of use.
- If you have laminate countertops, drop-in sinks are the only option: the particle board below the laminate surface isn`t strong enough to support undermount sinks but plays well with self-rimming basin types.
