Claims (1)

Предлагается высокопроизводительный способ дегазации и газации, а также установка для дегазации или газации термопластичных полимерных расплавов, высокомолекулярных полимеров или аналогичных, подлежащих дегазации, текучих до труднотекучих материалов. Вспененная смесь расплава со средством-носителем подвергается механическому, пеноразрушающему эффекту, подается в высокопроизводительный дегазационный экструдер, расплав распределяется тонкими слоями на большой площади и подвергается воздействию дегазационного давления одновременно по всему технологическому тонкослойному диапазону.A high-performance method of degassing and carbonation is proposed, as well as an installation for degassing or carbonation of thermoplastic polymer melts, high molecular weight polymers or similar, subject to degassing, flowable to difficult flowing materials. The foam mixture of the melt with the carrier medium is subjected to a mechanical, foam-destructive effect, is fed into a high-performance degassing extruder, the melt is distributed in thin layers over a large area and is exposed to the degassing pressure simultaneously over the entire process thin-layer range.
