| Most of the domestic kaolin is the coal gangue of the coal mine. The coal gangue has been crushed and ground, and the natural taste is low and the composition of kaolin is complex.
Although there is a subsequent treatment, the processing technique is coarse, various Fe element Na elements and impurities content are high, in which calcining kaolin can be used in the wire and cable industry.
However, due to the unstable source of coal gangue, the quality of calcined kaolin is uncontrollable and the batch is volatile.
The calcining method is completely calcined and not completely calcined.
Basf kaolin SP - 33 is USES is the sea mine kaolin ore deposit type, it is located in Georgia kaolin ore with a 800 - kilometre, adopts the strict temperature control burn of metakaolin.
The kaolin is absorbed in the wire and cable free of the characteristics of acid radical ion, no matter in wet or dry environment, can guarantee the high resistivity, low dielectric constant and long service life.
This stability and acid-absorbing capacity are not comparable to the domestic kaolin. |
