Metal silicon,
also known as Crystalline Silicon or Industrial Silicon, is mainly used
as an additive to non-ferrous based alloys. Metal silicon
is a product made of quartz and coke in an electric furnace. The content
of silicon in the main component is about 98% (in recent years, 99.99%
of Si is also contained in metal silicon), and the remaining impurities
are iron and aluminum. , calcium, etc. Silicon Metal,Metallic Silicon,Crystalline Silicon,Industrial Silicon Ningxia Evergreen Trading Co., Ltd. , https://www.nxevergreen.com
We will also often encounter corrosion caused by corrosion of screws for a long time, and it is difficult to remove, even the nuts can not be removed. However, it had to be dismantled for maintenance or overhaul, which caused great inconvenience to our work. To solve the problem that it is difficult to remove the screws, generally we will take some measures, such as releasing the moving agent, burning, oiling, sawing and crushing. The loosening agent can be used when the surface is rusted and the extent of rusting is not so severe. Because of the severely rusted screws, the loosening agent can hardly penetrate the inside of the screw and cause a chemical reaction to occur. It is often rusted by some stains on the surface. In addition, it takes a long time to work. It often takes time to repair or repair. It cannot wait for a long time, and it will affect the next step because of a rusted screw. The progress of work, so it is not a good choice.
