Anti-corrosion lubricating type high-water-based packing

Abstract

The invention discloses an anti-corrosion lubricating type high-water-based packing. The high-water-based packing comprises a body; the body is formed by weaving anti-corrosion fibers; the surface of the body is coated with a lubricating layer; the lubricating layer is formed by mixing graphite and bentonite, wherein the content of the graphite accounts for 80-90% by mass percentage, and the content of the bentonite accounts for 10-20% by mass percentage; the anti-corrosion fibers are obtained by soaking ramie fibers in an anti-corrosion soaking solution; and the anti-corrosion soaking solution is formed by mixing mica powder and paraffin oil, wherein the content of the mica powder accounts for 3-7% by mass percentage, and the content of the paraffin oil accounts for 93-97% by mass percentage. The high-water-based packing has the advantages that by means of the mode, both the corrosion resistance and the high lubricating property can be achieved, and therefore the friction coefficient of a product can be greatly decreased, the abrasion to a shaft is precious little, in addition, the service life in a severe environment can be greatly prolonged, and the product quality is high.

Description

technical field [0001] The invention relates to the technical field of sealing packing, in particular to an anti-corrosion lubricating high water base packing. Background technique [0002] In the shipbuilding industry, rotating equipment, reciprocating pumps, and valve sealing packing installation and use, cotton yarn reinforced flexible graphite packing is usually used as the preferred sealing packing. However, due to the limitation of the characteristics of the graphite material itself, after its tensile strength and compressive strength are strengthened by vegetable fibers, there are still many deficiencies when used in environments with high requirements such as high strength and high thread counts: replace the seal When fitting, it is often found that the flexible graphite packing is damaged in advance, and the surface of the sealing parts that it contacts also has corrosion of varying severity, resulting in rust and deformation of the valve stem, resulting in large ec...
