Description
Technical field
The present invention relates to a kind of damping agent, relate in particular to the damping agent that a kind of brass part is used.
Background technology
Brass is because the application of its superior processing characteristics and corrosion resisting property is very extensive, and the application quantity in non-ferrous metal is only second to aluminium and aluminium alloy, is conventionally applied to structural parts and solidity to corrosion part, as flange, valve, support, pointer and axle etc.The pointer of instrument, because extraneous vibrations easily cause shake, causes pointer to be difficult to stablize, and makes reading difficulty, brings inconvenience to productive life.Therefore consider between the axle of pointer and bearing and add damping agent, be used for slowing down this jitter phenomenon.Existing damping agent is by the compositions of mixtures (viscosity is 450 lis and drags) of silicone oil (10%) glycerol adding (90%), but the price of silicone oil is very high, be probably 500-1000 unit/kilogram, make cost improve; And the viscosity of mixture is very high, can make in use pointer be difficult to deflection, affect the sensitivity of instrument.Therefore suddenly wait to find a kind of low price, stable performance, the damping agent that result of use is good.
Summary of the invention
Main purpose of the present invention is, overcome the defect that existing damping agent exists, and provide a kind of novel damping agent for brass part, technical problem to be solved is to reduce the manufacturing cost of damping agent, the damping agent stable performance simultaneously making, thereby be more suitable for practicality, and there is the utility value in industry.
The object of the invention to solve the technical problems realizes by the following technical solutions.A kind of damping agent proposing according to the present invention, the component that described damping agent comprises following massfraction, wherein glycerine is 85%～95%, and distilled water is 1%～4%, and dehydrated alcohol is 3%～10%, and benzotriazole is 0.1%～0.8%, urea is 0.1%～1%.
Aforesaid damping agent, the component that described damping agent comprises following massfraction, glycerine is 90%～95%, and distilled water is 2%～3%, and dehydrated alcohol is 4%～7%, and benzotriazole is 0.2%～0.5%, urea is 0.2%～0.5%.
Aforesaid damping agent, the component that described damping agent comprises following massfraction, glycerine is 90.7%, and distilled water is 2.9%, and dehydrated alcohol is 5.8%, and benzotriazole is 0.3%, urea is 0.3%.
Aforesaid damping agent is shaken for the brass part that slows down instrument.
By technique scheme, the present invention at least has following advantages for the damping agent of brass part:
Damping agent modest viscosity prepared by the present invention, had both solved the problem of instrument shake, can not affect the sensitivity of instrument simultaneously; In damping agent, add suitable inhibiter, effectively prevent the corrosion to brass parts simultaneously.
Above-mentioned explanation is only the general introduction of technical solution of the present invention, in order to better understand technique means of the present invention, and can be implemented according to the content of specification sheets, below is described in detail as follows with preferred embodiment of the present invention.
Brief description of the drawings
Fig. 1 is the polarization curve of electrochemical process test inhibition efficiency of the present invention.
Embodiment
Technique means and effect of taking for reaching predetermined goal of the invention for further setting forth the present invention, to its embodiment of the damping agent for brass part, feature and effect thereof of proposing according to the present invention, be described in detail as follows.
Embodiment 1
In order to make sweet oil viscosity reach 300～500 lis of holders, because glycerine has stronger water-absorbent, the water suction of glycerine can make reduced viscosity, need to add volatile material and stablize sweet oil viscosity, under relatively airtight working conditions, select the stablizer of dehydrated alcohol as viscosity, stablize sweet oil viscosity by the volatilization of dehydrated alcohol, what this formula adopted is glycerine: distilled water: dehydrated alcohol (volume ratio)=50:2:5, it has satisfactory stability and viscosity temperature characteristic, product configures the viscosity of rear ten days and is changed to 470 lis of holders and is increased to 472 lis of holders, velocity of variation is about 0.43%.
Because the variation of environment for use temperature is larger, need to there is good viscosity temperature characteristic, the variation of the viscosity with temperature of this formula is as following table:
Viscosity is along with the variation of temperature
Therefore, be well suited for using under 14～34 DEG C of conditions.
Formed by glycerine, distilled water and ethanol, brass is had to stronger corrodibility, need to add inhibiter and regulate applicable pH value to slow down the corrosion to brass.This corrosion inhibitor formula adopts: the benzotriazole (BTA) of 3000ppm and the urea of 3000ppm, then using sodium hydroxide (NaOH) to regulate PH is 10.5, there is good corrosion inhibition, testing weightless by weight loss method is 9.1mg, and the weightlessness of check sample is 23.5mg, calculating inhibition efficiency is 61.3%.
The inhibition efficiency of testing by electrochemical tests is 46.6%, specific as follows:
With 59-1 brass electrode, (curve a) He not adds that (curve b) has been made E-I anodic polarization curves (note: because cathodic polarization is subject to the diffusion control of H+ in the solution of inhibiter adding, so cathodic polarization curve be can not make), be converted to η-lgI curve (as Fig. 1) by formula.
Can find out from these two polarization curves, add after inhibiter, it is steeper that polarization of electrode curve can become, and this inhibiter adding with regard to explanation has certain inhibition efficiency, and this has also just verified experimental result above, can calculate thus inhibition efficiency.
Can know from the Ta Feier straight-line extrapolation of two anodic polarization curves and the intersection point of X-coordinate, the membership that adds of inhibiter reduces the corrosion current of brass.The intersection point of curve a and X-coordinate is 0.675, and the intersection point of curve b and X-coordinate is 0.925; Can calculate thus spontaneous corrosion electric current separately as follows:
∵Ia=4.677×10
-4mA ∴lgIa=0.675
∵Ib=8.750×10
-4mA ∴lgIb=0.925
Just can be calculated the inhibition efficiency (because the area of electrode is the same, so can calculate inhibition efficiency with corrosion current) of inhibiter by two data above:
η=（Ib-Ia）÷Ib×100%
η=（8.750-4.677）÷8.750×100%=46.6%
The inhibition efficiency being calculated by polarization curve is 46.6%.
End formulation is (massfraction): glycerine: 90.7, and distilled water: 2.9, dehydrated alcohol: 5.8, benzotriazole: 0.3 and urea: 0.3.
The present invention that above-mentioned structure like this forms, for the technological innovation of the damping agent of brass part, all has many saving graces for technician of the same trade now, and the progressive that really possesses skills.
The above, it is only preferred embodiment of the present invention, not the present invention is done to any pro forma restriction, although the present invention discloses as above with preferred embodiment, but not in order to limit the present invention, any those skilled in the art, do not departing within the scope of technical solution of the present invention, when can utilizing the technology contents of above-mentioned announcement to make a little change or being modified to the equivalent embodiment of equivalent variations, in every case be the content that does not depart from technical solution of the present invention, any simple modification of above embodiment being done according to technical spirit of the present invention, equivalent variations and modification, all still belong in the scope of technical solution of the present invention.
