Abstract

The invention discloses a high silica glass fiber sealed woven substrate for a chemical raw material production machine. The high silica glass fiber sealed woven substrate comprises an inner core layer and a skin layer, wherein the inner core layer adopts a high silica glass fiber bundle; the skin layer adopts a high silica glass fiber yarn using S-twist with the twist degree of 80 to 100 twists;the high silica glass fiber adopts Z-twist 100 to 200 twist self-twisting; the skin layer is wound clockwise on the outer surface of the inner core layer; the inner core layer is provided with a silane coupling agent and an antistatic agent. The high silica glass fiber sealed woven substrate disclosed by the invention overcomes the difficulties of high rigidity and difficulty in forming of carbonfibers adopted in traditional sealing materials; the application adopts the high silica glass fiber and has the characteristics of aging resistance, good sealing property and high corrosion resistance.

Description

technical field [0001] The invention relates to a sealing braided substrate used for manufacturing seals of food processing machinery, in particular to a high-silica glass fiber sealed braided substrate used in chemical raw material production machinery and a preparation method thereof. Background technique [0002] The sealing element is installed in the sealing box, and the sealing element is pressed on the surface of the shaft through the sealing gland. Because the surface of the shaft is always somewhat rough, it can only be partially attached to the seal, but partially not in contact, thus forming countless labyrinths. When the pressurized medium passes through the surface of the shaft, the medium is throttled several times, and the seal is achieved by virtue of this "labyrinth effect". The fit and friction between the seal and the shaft surface are also similar to sliding bearings. There should be enough liquid for lubrication to ensure that the seal has a certain lif...
