Infiltration pottery solution is by following proportion by weight:
Workpiece after infiltration pottery preservative treatment has high-intensity corrosion performance, and infiltrates the characteristic of pottery technique, it is ensured that metal
Part inner and outer surfaces all can be penetrated into uniformly, thus ensures the antiseptic property of metal parts.Owing to all of of corrosion can be caused
Metal parts has been respectively provided with high-strength antiseptic property, and therefore, working media can use common neutral water to replace emulsion solution, again
Excellent lubricity and high case hardness after processing due to infiltration pottery so that the post 2 frictional dissipation with Y shape rubber seal of living
The ability that extremely low, anti-shell etc. destroy is strong, thus realize in useful life non-maintaining.
Use infiltration pottery technique that the metal parts of individual prop is carried out anticorrosion and intensive treatment, individual prop is greatly improved
Resistance to all kinds of corrosive power, improves case hardness and the intensity of individual prop metal parts simultaneously, improve individual prop shock resistance,
Anti-shell ability.The antiseptic property of its excellence makes individual prop that neutral aqueous media only need to be used can to meet underground coal mine use will
Asking, be substantially reduced management and the use cost of ore deposit side, non-maintaining in can realizing the use cycle, service life is much higher than general simultaneously
Logical individual prop, the regular service conditions lower life-span was up to 10 years.
Use the present invention to solve the difficult point that mine individual hydraulic prop antiseptic power is poor, emulsion pollutes environment, increase
Mine individual hydraulic prop uses the time at work surface, extends the use cycle of mine individual hydraulic prop, useful life
Inside accomplish non-maintaining, realize zero emission simultaneously.
Further, owing to employing infiltration pottery anticorrosion process, the metal parts being easily generated corrosion all " has been put on firm
Protective clothing ", the antiseptic power of whole individual prop is greatly improved, and infiltrates the metal parts outer surface after pottery more
Smooth, roughness is lower, thus less with the frictional resistance of sealing member, and sealing property is more preferable, non-maintaining in can realizing lifetime.
