Description

Изобретение касается производства искусственных пористых заполнителей для бетонов.The invention relates to the production of artificial porous aggregates for concrete.

Известно использование для производства искусственного пористого заполнителя (керамзита) легкоплавкой глины [1].Known use for the production of artificial porous aggregate (expanded clay) fusible clay [1].

Задачей изобретения является упрощение технологии производства пористого заполнителя.The objective of the invention is to simplify the production technology of porous aggregate.

Технический результат достигается тем, что сырьевая смесь для производства искусственного пористого заполнителя, содержащая легкоплавкую глину, дополнительно содержит измельченные и просеянные через сито №5 отходы производства древесно-волокнистых плит – обрезки, бракованные изделия при следующем соотношении компонентов, мас.%: легкоплавкая глина 97,0-99,5; указанные отходы производства древесно-волокнистых плит 0,5-3,0.The technical result is achieved in that the raw material mixture for the production of artificial porous aggregate containing fusible clay, additionally contains crushed and sifted through a sieve No. 5 waste products for the production of wood-fiber boards - scraps, defective products in the following ratio, wt.%: Fusible clay 97 0-99.5; the specified production waste of wood-fiber boards 0.5-3.0.

В таблице приведены составы сырьевой смеси для производства искусственного пористого заполнителя.The table below shows the composition of the raw mix for the production of artificial porous aggregate.

Figure 00000001
Figure 00000001

В составе сырьевой смеси используют любые легкоплавкие глины, склонные к вспучиванию при быстром обжиге, например глины монтмориллонитовые, включающие Аl-монтмориллонит и Fe-монтмориллонит (нонтронит); отходы (обрезки, бракованные изделия) производства древесно-волокнистых плит.The composition of the raw material mixture uses any low-melting clay, which is prone to swelling during rapid firing, for example montmorillonite clays, including Al-montmorillonite and Fe-montmorillonite (nontronite); waste (trimming, defective products) production of wood-fiber boards.

Измельченные и просеянные через сито №5 отходы производства древесно-волокнистых плит смешивают с легкоплавкой глиной и готовят сырьевую смесь с влажностью 19-26%. Из полученной смеси формуют гранулы, которые сушат и обжигают в интервале температур 980-1100°С.Shredded and sifted through a sieve No. 5 waste products from the production of wood-fiber boards are mixed with low-melting clay and a raw mix with a moisture content of 19-26% is prepared. Granules are formed from the resulting mixture, which are dried and fired in the temperature range 980-1100 ° C.
