Foundry Perlite features
1, the slag and foreign body can be assembled into the casting solution, and the slag and the foreign body can be easily removed.
2, on the surface of the casting solution, the slag and the foreign body are aggregated to prevent the slag and the foreign body from entering the castings.
3, produced by professional manufacturers, always keep quality stable.
4. When using small ladle, it can cover the light - proof reflection, and the operation is convenient.
5, the chemical composition of the casting solution will not be changed.
6. Compared with the same kind, the addition of the weight less, can play a better slag removal effect.
Expanded Perlite Usage
It can be used in oxygen manufacturer and freezer as well as insulating layer in transporting liquid oxygen and hydrogen.
It can be sused to filter liquor,oil,medicine,food and dirty water.
It can be used as filling and dilating agent in rubber,painter and plastice,etc.
It can be used as catalyst in explosives.
It can be used to absorb floating oil.
It canbe used in agriculture and gardening to improve the soil and withhold water and fertilizer.
It can be mixed with different benders to make templets of different sizes and functions.
It can be used as in large volume as insulating layers in industrial smelting furnaces and walls and floors of architectures
