Abstract
The invention relates to a method for cleaning dust on the surfaces of precision instruments. The method includes filling tanks with liquid nitrogen; cleaning the dust by the aid of the liquid nitrogen (with the dosage of 500-800ml/m<2>); wiping the surfaces of the precision instruments by the aid of cotton balls with ethyl alcohol or ethyl ether; further cleaning the dust by the aid of the liquid nitrogen (with the dosage of 200-400ml/m<2>); wiping the surfaces of the precision instruments again by the aid of cotton balls with ethyl alcohol or ethyl ether. The method has the advantages that the surface dust cleaning time can be greatly shortened, the precision, the sensitivity, the light transmittance and the stability of the precision instruments can keep unchanged; the method is wide in application range, low in cost and simple in operation.
Description
Technical field:
The present invention relates to a kind of method for cleaning, specifically a kind of method for cleaning of precision instrument surface dirt.
Background technology:
Laboratory apparatus is the necessary equipment of deep Knowing material tissue and performance.The operation and maintenance of laboratory apparatus just seems very important like this.Especially the operation and maintenance of precision instrument, a lot of for the method for cleaning of precision instrument surface dirt, traditional method mainly contains that dry cloth wipes, towel is brushed lightly brush, banister brush brush, skin purt, ear washing bulb formula inflator air blowing dedusting etc.But some precision instruments are after above-mentioned cleaning, and instrument can damage.Such as precision reduction, sensitivity decline, light transmittance decline, stability decreases etc.And time-consuming, the effort, costly of precision instrument surface dirt cleaning, complex operation, clearance time is longer, and cleaning cleanliness factor is poor.
Summary of the invention:
Precision instrument maintaining and maintenance, normally carrying out of experiment will be beneficial to, be conducive to the employing of new experimental technique, be conducive to the raising of experimental level, can avoid the generation of experiment accident, can expand the scope of application of instrument, can extend the service life of instrument and equipment, this is just equivalent to the increase of instrument production output and the raising of quality.Scientific and reasonable use habit and maintaining method, the extent of deterioration of lowering apparatus greatly, otherwise easily cause the appearance of instrument variety of issue: precision reduces, poor stability, observation interface (form) is unintelligible etc., especially various precision detecting instruments, need user of service's extraordinarily care.
Once precision instrument adsorbs dust, dirt, not only affect the performance of instrument, reduction of service life, directly affect experiment effect, and affect attractive in appearance and physical and mental health experimenter.Instrument all can be stained with dust and dirt in using or preserving, and it is main accomplishing to prevent dust antifouling, and dedusting cleaning is the important step of doing instrument maintenance well frequently.
The grey dust collecting method of removing at present precision instrument surface is a lot, the degree that mainly should adhere to according to situation and the dust thereof of dust attaching surface and determining.In dry air, if dust is less or dust not yet makes moist, form piece spot, the method such as available dry cloth wipes, and towel is brushed lightly brush, banister brush brush, removes the dust on general instrument; To the dust of instrument internal, can use skin purt, ear washing bulb formula inflator air blowing dedusting, also available dust catcher dust suction; Dust in diagonal angle, seam can combine dedusting by above-mentioned several method.But to the precise instrument, as first-class in optical instrument, instrument, with said method dedusting, also can damage instrument, now should adopt special dust removing tool dedusting, as wiped with lens paper, be stained with spirituous cotton balls and wipe etc.Dust mostly is the small dust with micro-static, often flies in air, with air-flow, moves, and meets thing and just adheres on it, almost all-pervasive.Dust is attached on archetype can affect its color and luster, has dust can increase wearing and tearing on moving component, has dust on electrical equipment, and severe patient can cause short circuit, electric leakage, has dust on the precise instrument, and severe patient can make instrument scrap.There was dampness in the air, when dust has been formed dirty piece, dedusting should adopt wet cloth to wipe, and the black dirt in diagonal angle, seam can be first with soft large the rejecting of fining away, then with wet cloth examination wiping, still to the surface of fading, electrical equipment, should not wipe with wet cloth.If black dirt is difficult for wiping totally, the available cotton balls that speckles with alcohol or second fan wipes, or cleans.
The present invention is the deficiency that overcomes the existing surface dirt method for cleaning of precision instrument, provides a kind of and can keep the constant surface dirt method for cleaning of precision instrument precision, sensitivity, light transmittance and stability.
The object of the invention is to adopt following technical proposals to realize.A method for cleaning for precision instrument surface dirt, comprise utilize homemade cylindrical tank to pack the cleaning of liquid nitrogen, liquid nitrogen into (consumption is 500-800ml/m
2), the cotton balls that speckles with alcohol or second fan wipes, liquid nitrogen further clears up that (consumption is 200-400ml/m
2), the cotton balls that speckles with alcohol or second fan wipes again.
The Analysis on Mechanism of liquid nitrogen cleaning precision instrument surface dirt
Liquid nitrogen is the liquid form that nitrogen forms at low temperatures.Be inertia, colourless, odorless, non-corrosiveness, non-combustible, temperature is extremely low.Form the major part (volume ratio 78.03%, weight ratio 75.5%) of atmosphere, its character torpescence, does not support burning, and relative vapor density (air=1) is 0.97.
Because the temperature of liquid nitrogen when the normal pressure is quite low, once will promptly seethe with excitement with precision instrument Surface Contact, on precision instrument surface, do random motion fast, simultaneously liquid nitrogen on precision instrument surface rapidly volatilization be nitrogen, by liquid state then become gaseous state.Because liquid nitrogen is 0.97 with respect to the density of steam, the density that is to say liquid nitrogen is less than air, and precision instrument surface is with the small dust of micro-static like this, will fly on nitrogen, with air-flow, move, depart from precision instrument surface, reach the object of removing precision instrument surface dirt.Liquid nitrogen temperature is lower simultaneously, also removes the steam of precision instrument inside when removing precision instrument surface dirt, prevents that precision instrument from making moist, and affects certainty of measurement.
The present invention has the following advantages:
1, can greatly shorten the time of surface dirt cleaning.
2, can keep precision instrument precision, sensitivity, light transmittance and stability constant.
3, this method accommodation is wider, and cost is lower, simple to operate.
The specific embodiment:
Below in conjunction with embodiment, the present invention will be further described.
Embodiment 1: a kind of method for cleaning of precision instrument surface dirt, comprises that (consumption is 580-760ml/m to the cleaning of liquid nitrogen tinning, liquid nitrogen
