| description | Now slate in Kazakhstan is produced at two modern plants in Semey (Semipalatinsk Plant of Asbestos - cement Products LLP-the largest of the two) and Shymkent (Tectum Engineering LLP). Currently, Kazakhstan consumes about 5 million sheets of slate per year, of which last year Kazakh enterprises produced 2.5 million with plans to increase production. Previously, all this volume was imported from abroad. The most loyal consumers are the southern regions, where, due to the hot climate, people remember and know how to handle slate, knowing its properties. For comparison, in Uzbekistan, about 35 million sheets of slate are consumed per year. The production of construction and technical products based on asbestos is accompanied by the formation of a significant amount of asbestos dust. At the same time, the main contribution to atmospheric air pollution is made by dust emissions with particle sizes up to 10 microns. In the industry's established practice, cyclones and bag filters are the most widely used for dedusting emissions. Experience of operation of these devices shows that due to the nature of the physico-chemical properties of asbestos dust required collection efficiency is not achieved (most of the fine fraction with particle sizes less than 5 μm cyclones virtually trapped; bag filters clogged fibrous asbestos dust), resulting in the concentration of dust in the air on the border of the sanitary protection zone of the enterprise is 7-10 times higher than the standard MPC. |
