The development trend of Ye Lashi
Ye Lashi is a crystalline structure. It belongs to layered silicate minerals. Its crystal structure is composed of two layers (Al-O, OH) and eight layers in the middle layer of the upper and lower layers (Si-O) and tetrahedral layers. The structure Al2[Si4O10] (OH) 2, the experimental formula is Al2O3 - 4H2O, the chemical composition theory of Al2O328.3%, SiO266.7%, H2O 5%, nature rarely see pure pyrophyllite, often associated with various impurities. Ye Lashi crystal is monoclinic, usually flake, radial aggregates, with pearly iridescence or aphanitic scaly dense block, usually white, light yellow or light green, white streak, vitreous luster, from pearl luster, waxy luster to dull, supple, with greasy feeling, the bulk density of 2.75 ~ 2.80g/cm3, Mohs hardness of 1.5 ~ 2. In 600 ~ 700 degrees have a balanced endothermic Valley to 1000 DEG C has no exothermic peak, this is because the pyrophyllite dehydration after the structure is not damaged, no crystallization of new and with reason.
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
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.
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?
Can the production of pyrophyllite brick used in ladle, Zhejiang, Shangyu refractories company is the production of self-supporting brick, you can sell his house or sell their brick production plant.
