Packing from the high-water-based high-quality specialty fibers woven from ramie, which, treated with preservatives carbon, full infiltration of special lubricants. Highlight the advantage of very low friction coefficient, not grinding axes, anti-corrosion. In the shipbuilding industry, water treatment, water and oil on the application of cold is particularly ideal. Used in low-pressure valves, rotating equipment and reciprocating pump hydraulic press machine, such as ship propeller. Applicable to a variety of water quality, water, salt water, oils, lipids, weak acid, weak base, such as, in particular abrasive ability.
