Изобретение относитс к обласSH уплотнений и может найти применение в ариатуростроении.This invention relates to seals and can be used in ariaturostroenii.
Известна пластична набивка н& основе асбеста, выпускаема промншленностью дл тепловых элентро станций и используема дл уплотнени сальников паровой аиматтры при температур до 60041. Эту набивку невоамохно использовать в качестве уплотнени среды, имею щей температуру 800-1000°С м сосхо щеД из конвертированного и дннового газов.Known plastic packing based on asbestos produced by industrial thermal power stations and used to seal the glands of the steam aimattra at temperatures up to 60041. This gasket is not peaceful and should be used as a sealing medium having a temperature of 800–1000 ° C using converted and bottom gases .
В цел х придани устойчивости к высоким температурам и агрессивным средам в предлагаемую набивву введена следа и компоненты вз ты в следующих количествах , ъвс%:In order to impart resistance to high temperatures and aggressive media, a trace is introduced into the proposed stuffing and the components are taken in the following quantities,%:
