Description
Известен способ получени теплоизол ционных изделий из вспученного перлита с различными св зками (цемент, известь, битум ), заключающийс в том, что вспученный перлит смешивают со св зкой, формуют издели и производ т термообработку.A known method for producing heat insulating products from expanded perlite with various bonds (cement, lime, bitumen) consists in that the expanded perlite is mixed with the binder, molded products and heat treated.
Цель изобретени - уменьшить объемный вес изделий до 120-180 . Дл этого в качестве св зки используют ортофосфорпую кислоту в количестве 10-12о/о от веса перлита .The purpose of the invention is to reduce the volume weight of products to 120-180. For this purpose, orthophosphoric acid in the amount of 10-12 o / o by weight of perlite is used as a binder.
Исходными материала.ми дл изготовлени теплоизол ционных изделий служат перлитовый песок, ортофосфорна кислота и технологическа вода.Perlite sand, orthophosphoric acid and process water are the starting materials for the manufacture of thermal insulation products.
Ортофосфорную кислоту, разбавленную технологической водой, ввод т во вспученный перлитовый песок и смешивают в мешалках непрерывного и принудительного действи . Количество песка, кислоты и воды подбирают в зависимости от заданного объемного веса.The phosphoric acid, diluted with process water, is introduced into the expanded perlite sand and mixed in continuous and forced agitators. The amount of sand, acid and water is selected depending on the desired volumetric weight.
Издели заданных размеров и конфигураций формуют на механических или гидравлических прессах двустороннего прессовани при удельном давлении 2-3 кг/ежа, с коэффициентом спрессованности (отношение высоты засыпки в форму к высоте спрессованного издели ) 1,9-2,1.Products of specified sizes and configurations are formed on mechanical or hydraulic double-sided presses with a specific pressure of 2-3 kg / hedgehog, with a compression ratio (the ratio of the height of filling into the mold to the height of the pressed product) 1.9-2.1.
Твердение изделий происходит в такой последовательности: выдержка при комнатной температуре 24 час, термическа обработка в туннельных конвейерных или радиационных сушилках при температуре 280-300°С 12 час.Hardening of the products occurs in the following sequence: holding at room temperature for 24 hours, heat treatment in tunnel conveyor or radiation dryers at a temperature of 280-300 ° C for 12 hours.
Изготовленные описанным способом издели имеют следующие характеристики:The products made by the described method have the following characteristics:

Предмет изобретени Subject invention
Способ получени теплоизол ционных изделий путем смешивани вспученного перлита и св зки с последующим формованием изделий и термообработкой, отличающийс тем, что, с целью уменьшени объемного веса изделий до 120-180 кг/м, в качестве св зки используют Ортофосфорную кислоту в количестве 10-120/0 от веса перлита.The method of obtaining heat insulating products by mixing expanded perlite and binder, followed by molding and heat treatment, characterized in that, in order to reduce the bulk weight of the products to 120-180 kg / m, 10 to 120 / 0 by weight perlite.
