Abstract
The invention discloses a method for improving the corrosion resistance of a cylinder barrel of a mine single hydraulic prop. The method is characterized by comprising the following steps: pre-degreasing and mounting a clamp; assembling the degreased cylinder barrel and the clamp, chemically degreasing and washing; washing by clear water until no residual alkali solutions are on the part surfaces; completely removing attachments on the part surfaces; washing by acid; flushing; electroplating a nickel-phosphorus-cobalt alloy coating layer; washing; passivating; drying by an iron; and disassembling the clamp. According to the method, an emulsion medium can be fully replaced with a water medium, which is favorable for environmental protection; and the corrosion resistance is superior to a zinc-nickel alloy coating layer outside the cylinder barrel of the mine single hydraulic prop.
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 the mine coal work carried out prop drawing in the face of mine individual hydraulic prop, the workman need to spray into the minery with a part of emulsion, in order to prevent the corrosion of obnoxious flavour and corrosive goods confrontation cylinder barrel.Each circulation of coal-face sprays into the worked-out section with regard to the emulsion that 300-400L is arranged, according to statistics, the annual emulsifying agent that consumes is 6000 tons, and the emulsion of these consumption flows in river, river, lake even the mineral spring through various channels, and is extremely serious to the pollution of water and environment.Study simultaneously and produce the producer of emulsion, stable for product in order to improve the rot-resistant performance, add a large amount of additives at emulsifying agent, and additive all is harmful, havoc environment.Therefore the colliery requires the mine individual hydraulic prop of manufacturer production water medium for saving cost, but because hydraulic prop is the 27SiMn earthen pipe, the self-preserving ability, and water medium is to its basic unprotect effect, thereby usually is not accepted.Wei the Full foot market requirement, it is very necessary 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, a kind of enhancing mine individual hydraulic prop cylinder tube anti-corrosion method is provided.Purpose of the present invention realizes 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 washing part 2-3 minute in the tap water, remove remaining grease-removing agent;
2, clamping tool is with the cylinder barrel after the degreasing and Fixture assembly;
3, chemical degreasing is at first prepared chemical skim soln, with Na
2CO
3, Na
2SiO

4Insert in the rinse bath after fully mixing by 14-16:1:14-16:67-71 with water, will insert in the chemical degreasing groove with the good mine individual hydraulic prop cylinder tube of Fixture assembly again and soak 20-30 minute, need upper and lower shake several therebetween;
4, clean, clean to piece surface noresidue alkali lye with clear water, thoroughly remove the piece surface dirt settling;
5, pickling is immersed cleaned mine individual hydraulic prop cylinder tube in the 15-20%HCl liquid together with anchor clamps, washes surface scale off and removes corrosion product with mechanical process;
6, flushing is rinsed the piece surface dirt settling well with flowing water for subsequent use;
7, electronickelling phosphorus boron cobalt-base alloy coating is prepared first nickel phosphorus boron cobalt alloy plating solution, presses: ZnO:NaOH:NZ-918C:NZ-918A:NZ-918B:NiSO
4.6H
2O:PO:Co: two water=8-12:80-100:40-60:0-6:3-5:8:2:1:600-700 weightmeasurement ratio preparation electroplate liquids that heat up in a steamer, and place the electrodeposit groove, mine individual hydraulic prop cylinder tube for subsequent use after cleaning is placed plating tank together with anchor clamps, at annode area: cathode area=1.5-2:1, current density: 0.5-4.5A/dm2, temperature: electroplated 25-35 minute under the 30-35 degree condition;
8, clean, water cleans removes piece surface alkali lye, cleans remaining alkali lye with 70-100 degree hot water again;
9, passivation places the passivation of NZ-918E 2-35ml/L passivating solution with the mine individual hydraulic prop cylinder tube together with anchor clamps, and part must swing during passivation, and part stops 0-15 second after the passivation in air;
(10) embathe, part is immersed in flowing water cleaning in the soaker;
(11) dry, part is placed in the dry groove, the dry 1-5 of 70-80 degree minute, during upper and lower shake 2 times;
(12) dismounting fixture.
When nickel phosphorus boron cobalt-base alloy thickness of coating is 0.015-0.020mm, chromatic passivation after the nickel content 10%-14% plating.
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 mine individual hydraulic prop cylinder tube and adds zn-ni alloy deposits.
The boron cobalt plays anti abrasive effect in coating stronger.After testing, product indices of the present invention is:
(1) porosity checks that by the MT/T335-1995 standard voidage is 0.
(2) bonding force adopts pliability test and heat test, as long as pre-treatment is strict, bonding force is good in the coating obscission.
(3) hardness of nickel phosphorus, hardness is from 360(HV after thermal treatment) be increased to 850(HV); The hardness of nickel phosphorus boron, hardness is from 1200(HV after thermal treatment) be increased to 1465(HV); The hardness of nickel phosphorus boron cobalt, hardness is from 1480(HV after thermal treatment) be increased to 1950(HV).
(4) when coating during at 0.015-0.020mm, alternating bending is 3 times on vice, coating flawless and obscission.
(5) corrosion resistant test is pressed the GB6459 acetic acid salt spray test, and it is 920h that the white rust time appears in this coating passivation layer.Be 480h and the white rust time appears in zn-ni alloy deposits.
Can illustrate that from above data nickel phosphorus boron cobalt-base alloy coating all is better than zn-ni alloy deposits at the aspect such as corrosion-resistant, wear-resistant.From above-mentioned situation as can be known, the objective of the invention is to realize.
