Detailed Product Description: | Characteristics of a refractory mineral neutral, neutral refractory structure, chemical composition neutral refractories (Sericite) is a natural fine brick, is a subspecies of brick, silicate layered structure, double-layer structure of the silicon oxide layer of aluminum oxide octahedral consisting of two layers of silicon-oxygen tetrahedron tucked. Cleavage completely refractory Which is good, can be split into very thin sheet refractories wholesale, film thickness up to 1u below (theoretically be whittled 0.001u), radius to thickness ratio; compared with brick: a natural small size, ease of processing ultra-fine features. Neutral refractories crystal chemical formula:? K0.5-1 (Al, Fe, Mg) 2 (SiAl) 4O10 (OH) 2 nH2O, general chemical composition: SiO2 43.13 ~ 49.04%, Al2O3 27.93 ~ 37.44% Refractory Sales , K2O + Na2O 9 ~ 11%, H2O 4.13 ~ 6.12%. Brick shape should meet the requirements of quality brick shape quality should meet the following requirements: (1) size tolerance: height tolerance of soil 2%; wedge face and head width tolerance bulk soil 2mm; the difference between the size of the first soil tolerance 1mm; Length Tolerance ± 1%, but the biggest difference is the soil 2mm. (2) edge damage. Allow hot or cold surfaces damaged two sides reached 40mm long and 5mm deep; but not exceed. (3) Loss angle. Hot and cold surfaces are only allowed to have one corner refractory damage, loss angle at three edges and corners of damage does not exceed the length of 50mm. Does not exceed the loss angle of 20mm. (4) Crack. Tile allows fine hairline cracks; not allow cracks parallel to the bearing surface; no longer than 40mm, no wider than the other crack 0.2mm is allowed. (5) pits, melting tracks and drum kits. Allow pits and a maximum diameter of melting traces of 10mm, the maximum depth of 10mm; bulge maximum 0.5mm. There are a number of bricks of various edges of the brick shall not exceed 70% of the total.
