Description
Technical field
The present invention relates to a kind of hydraulic efficiency plant method of inhibiting corrosion, especially a kind of enhancing mine individual hydraulic prop cylinder tube anti-corrosion method.
Background technology
When mine coal work carries out prop drawing in the face of mine individual hydraulic prop, workman needs a part of emulsion to be sprayed into minery, in order to prevent the corrosion of obnoxious flavour and corrosive goods confrontation cylinder barrel.Each circulation of coal-face just has the emulsion of 300-400L to spray into worked-out section, according to statistics, the emulsifying agent of annual consumption is 6000 tons, and these emulsions consumed flow into river, river, lake even in mineral spring through various channels, extremely serious to the pollution of water and environment.Studying simultaneously and produce the producer of emulsion, stable in order to product, in order to improve rot-resistant performance, add a large amount of additive at emulsifying agent, and additive being all harmful, havoc environment.Therefore colliery is cost-saving, requires the mine individual hydraulic prop of manufacturer production water medium, but due to hydraulic prop be 27SiMn earthen pipe, self-preserving ability, water medium, to its basic unprotect effect, is not thus usually accepted.Wei the Full foot market requirement, it is very necessary for developing a kind of corrosion-resistant, anti abrasive mine individual hydraulic prop cylinder tube antisepsis technical method.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide a kind of and strengthen mine individual hydraulic prop cylinder tube anti-corrosion method.Object of the present invention is realized by following technical proposals, a kind of enhancing mine individual hydraulic prop cylinder tube anti-corrosion method, follow these steps to carry out: 1, pre-degreasing, dip grease-removing agent XH-9 with cloth and clean piece surface dirt, thick grease, and with rinsing part 2-3 minute in tap water, remove remaining grease-removing agent;

2o:BP:Co: two water=8-12:80-100:40-60:0-6:3-5:8:2:1:600-700 weightmeasurement ratio that heats up in a steamer prepares electroplate liquid, and be placed in plating tank, mine individual hydraulic prop cylinder tube for subsequent use after cleaning is placed in plating tank together with fixture, at annode area: cathode area=1.5-2:1, current density: 0.5-4.5A/dm
2, temperature: electroplate 25-35 minute under 30-35 degree condition;
8, clean, remove piece surface alkali lye with water cleaning, then clean remaining alkali lye with 70-100 degree hot water;
9, passivation, mine individual hydraulic prop cylinder tube is placed in the passivation of NZ-918E 2-35ml/L passivating solution together with fixture, and during passivation, part must swing, and after passivation, part stops 0-15 second in atmosphere;
(10) embathe, part is immersed in the cleaning of soaker flowing water;
(11) dry, part is placed in dry groove, the dry 1-5 minute of 70-80 degree, period upper and lower shake 2 times;
(12) dismounting fixture.
When nickel phosphorus boron cobalt zn alloy coating thickness is 0.015-0.020mm, chromatic passivation after nickel content 10%-14% plates.
The complete used water medium of product of the present invention replaces emulsifiable solution medium, is conducive to environment protection.Product Corrosion Protection of the present invention is better than the additional zn-ni alloy deposits of mine individual hydraulic prop cylinder tube.
It is stronger that boron cobalt plays anti abrasive effect in coating.After testing, product indices of the present invention is:
(1) by MT/T335-1995 standard, porosity checks that voidage is 0.
(2) bonding force adopts pliability test and heat test, as long as pre-treatment is strict, bonding force is excellent in coating obscission.
(3) hardness of nickel phosphorus, hardness is from 360(HV after heat treatment) be increased to 850(HV); The hardness of nickel phosphorus boron, hardness is from 1200(HV after heat treatment) be increased to 1465(HV); The hardness of nickel phosphorus boron cobalt, hardness is from 1480(HV after heat treatment) be increased to 1950(HV).
(4) when coating is at 0.015-0.020mm, alternating bending 3 times on vice, coating flawless and obscission.
(5) corrosion resistant test presses GB6459 acetic acid salt spray test, and this coating passivation layer occurs that the white rust time is 920h.And zn-ni alloy deposits occurs that the white rust time is 480h.
Can illustrate that nickel phosphorus boron cobalt zn alloy coating is all better than zn-ni alloy deposits in corrosion-resistant, wear-resistant etc. from above data.From above-mentioned situation, the object of the invention is to realize.
