FAQ

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 nature there is no pure graphite, which often contains SiO2, Al2O3, FeO, CaO, P2O5, CuO and other impurities. These impurities often appear in quartz, pyrite, carbonate and other minerals.
Ye Lashi's process technology
Pyrophyllite usually made crafts and milling and processing of pyrophyllite powder bleaching.Processing process of pyrophyllite, is determined according to the requirements of the product, such as for the production of refractories, firebrick of pyrophyllite, whiteness is not high, the product size is not very fine, the brick with leaf wax particle size is about 3mm, usually dry production.
Is Ye Lashi waterproof?
Pyrophyllite powder on the surface by coupling a layer of N- (Ding Ji) -3- aminopropyltrimethoxysilane (BAPTS) coupling agent activation,
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.
