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.
Ye Lashi's process technology
For ceramics, paper, pesticide carrier such as pyrophyllite, often in below 200 mesh fineness, whiteness of 85% or more, then the process in addition to coarse, medium and fine, but also with the suspension roller mill for grinding and dressing, or even bleaching in order to meet the requirement, then use wet method.Pyrophyllite for production of brick, pyrophyllite dosage is about 50-60%, the rest is clay, limestone and clay stone. Chinese the pyrophyllite mine at Fujian and Zhejiang two provinces, mining and processing plant are the main Fujian Fuzhou pyrophyllite ore, pyrophyllite ore etc. Fujian Shoushan pyrophyllite ore, Minqing County in Fujian.
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.
