| Specifications︰ | White, grey, Qiangongshai territories powder
Specification : 180~325 eyes |
| Advantages︰ | The sodium and calcium-base bentonite are used as the sand binder in green molding, surface drying molding, dried molding and pressure molding in cast iron and cast steel, which have a high strength high ore-carrying-resistance, high-temperature resistance and good repeatable-utilization, improve the surface finish and dimensional precision of castings, and reduce ratio of rejects. Especially the sodium-base bentonite as the mould sand binder has incomparable merits. |
| Export Markets︰ | Ore this high to expand multiple, fine hydroscopicity have , kind white degree have, unless composition the low, composition not concrete,physics and chemistry index please consultation |
