Modern equipment, professionalism of employees, strict adherence to GOST allow us to produce certified high quality products. Thanks to the growth of production capacity, improvement of the technological process, we were able to minimize production costs, which has a positive effect on the cost of the finished product. All these achievements, combined with high-quality raw materials, allow us to produce expanded clay with high performance characteristics. It is a building material with intact capsule shell integrity. Expanded clay gravel, manufactured in compliance with technological standards, does not change its original properties under the influence of temperature extremes. Producer of expanded clay "Kalita" - high quality standards of environmentally friendly products The production of expanded clay is carried out in special rotary kilns, in which drums are installed at a slight angle of inclination. Swelling of raw granules from natural low-melting clay occurs as a result of its rapid firing at a very high temperature. As a result of heat treatment, expanded clay becomes highly porous, but at the same time its outer surface remains strong and resistant to external factors. The porosity of the granules depends on the partial swelling of the mass by the gases formed and the rate of fuel burnout. Also of great importance is the rate of cooling of the production, which is reflected in the strength characteristics of the obtained expanded clay gravel. Слишком быстрое охлаждение приводит к растрескиванию, сохранению остаточного напряжения. В дальнейшем эти негативные последствия могут проявляться в бетоне. Если же после вспучивания процесс охлаждения проводить слишком медленно, то в связи с окислительными процессами возможно смятие размягченных гранул. Эксплуатационные харакиеристики готового продукта зависят не только от качества и режимов обработки исходного материала, но и от коэффициента вспучиваемости сырцовых гранул. Поэтому так важно соблюдать технологию на каждом производственном этапе. Керамзит от производителя ООО «Калита» обладает множеством замечательных свойств: высокая прочность при небольшом весе, устойчивость к низким и высоким температурам, отсутствие вредных примесей, высокая огнестойкость, устойчивость к грибковым образованиям, влагостойкость, высокая тепло и звукоизоляция. The company manufactures environmentally friendly products without the presence of impurities. In the arsenal of our enterprise there is a modern laboratory in which raw materials and finished products are subjected to physical and chemical quality control on a daily basis. The high characteristics of expanded clay gravel are documented by appropriate certificates. News © 2016 LLC "Kalita" - expanded clay blocks Articles Moscow , Kashirskoe sh., 70, bldg. 3.
