Description

technical field

[0001] The invention belongs to sealing, and in particular relates to a sealing material for a fluid medium, specifically a nano-packing packing, and also relates to a manufacturing method of the nano-packing. Background technique

[0002] In the field of sealing, sealing is usually divided into static sealing and dynamic sealing. Packing packing seals are widely used in static and dynamic sealing. When packing packing is used correctly, the sealing principle of packing packing will not be changed basically. At this time, the sealing performance of packing packing mainly depends on the sealing performance of packing packing. The material composition of the root packing requires that the packing should not only have the good compression rate, rebound rate and stress relaxation rate of the static sealing material, but also have the excellent toughness, tensile strength, recovery and other properties of the dynamic sealing material. Resistance, wear resistance,...
