Description

Изобретение относится к составам замазок, используемых для печей, тепловых агрегатов, приборов, работающих в условиях повышенных температур.The invention relates to compositions of putties used for furnaces, thermal units, devices operating at elevated temperatures.

Известна замазка, включающая, мас.%: корундовый порошок 30,0-33,0; смоляной компонент - остальное /1/.Known putty, including, wt.%: Corundum powder 30,0-33,0; resin component - the rest / 1 /.

Известна замазка, содержащая, мас.%: жидкое стекло 34,0-35,0; асбестовый порошок 5,0-6,0; корундовый порошок 32,0-34,0; тальк 4,0-7,0; порошок магнезита 16,0-18,0; кремнефтористый натрий 4,0-5,0 /2/.Known putty containing, wt.%: Water glass 34,0-35,0; asbestos powder 5.0-6.0; corundum powder 32.0-34.0; talc 4.0-7.0; magnesite powder 16.0-18.0; silicofluoride sodium 4.0-5.0 / 2 /.

Целью изобретения является повышение термостойкости замазки.The aim of the invention is to increase the heat resistance of the putty.

Цель достигается тем, что в состав замазки, содержащей жидкое стекло, асбестовый порошок, корундовый порошок, тальк, порошок магнезита, кремнефтористый натрий, дополнительно вводят шамот и хромит, при следующем соотношении компонентов, мас.%: жидкое стекло 23,0-25,0; асбестовый порошок 3,0-4,0; корундовый порошок 33,0-35,0; тальк 5,0-7,0; порошок магнезита 8,0-12,0; кремнефтористый натрий 3,0-4,0; шамот 8,0-12,0; хромит 8,0-10,0.The goal is achieved in that the putty containing liquid glass, asbestos powder, corundum powder, talcum powder, magnesite powder, sodium silicofluoride, additionally introduce chamotte and chromite, in the following ratio, wt.%: Liquid glass 23.0-25, 0; asbestos powder 3.0-4.0; corundum powder 33.0-35.0; talc 5.0-7.0; magnesite powder 8.0-12.0; sodium silicofluoride 3.0-4.0; fireclay 8.0-12.0; chromite 8.0-10.0.

В таблице приведены составы замазки, ее термостойкость /нагрев до 350°С с выдержкой 40 мин - охлаждение в воде 20°С с выдержкой 3 мин - воздушная сушка 20°С/.The table shows the composition of the putty, its heat resistance / heating to 350 ° C with a holding time of 40 min - cooling in water 20 ° C with a holding time of 3 min - air drying 20 ° C /.
