Ye Lashi's process technology
General use of magnetic separation; when the iron minerals as heavy metals, gravity can also be used; iron in the form of sulfide or oxide, the flotation can be used. The flotation method is also used for the separation of quartz and other impurities from pyrophyllite ore.
How to use the pyrophyllite refractory material, how to use, crushed, or powdered. Or block?
Powder is usually added to the refractory,Not much, just as additive, but also has the pyrophyllite brick.
Is Ye Lashi waterproof?
Pyrophyllite powder on the surface by coupling a layer of N- (Ding Ji) -3- aminopropyltrimethoxysilane (BAPTS) coupling agent activation,
The development trend of Ye Lashi
The main products: the characteristics and application of pyrophyllite line expansion coefficient is small, not before sintering in a certain temperature range (1050-1150 C) will produce line expansion, can offset the embryo in the firing caused by other materials in the process of contraction and expansion of this line, and on the firing range, ensure product size consistent. Ye Lashi has good thermal stability and very little moisture expansion, and can therefore be used to produce products of accurate size and good thermal stability.Properties and process trends
The catalytic purification of graphite powder can do what.
In addition, there are water, asphalt, CO2, H2, CH4, N2 and other parts of the gas. Therefore, the determination of graphite, in addition to the determination of fixed carbon content, but also the simultaneous determination of volatile and ash content.
