Abstract
The invention relates to an application of a drying agent in a moistureproof pressure-maintaining drying agent for a tightly sealed instrument which can work in a wet or underwater environment. The drying agent provided by the invention is composed of a substance A and a substance B, wherein the mass ratio of the substance A to the substance B is 1: 1-1.5; the substance A is a mixture of a peroxide or a peroxide with an uperoxide; and the substance B is an organic acid. The drying agent has strong water absorption and can rapidly release nontoxic and tasteless oxygen with the maximum water absorption amount being 24% of its weight and the maximum oxygen release amount being 44% of its weight. The drying agent becomes a white powder after absorbing water, is suitable for an instrument which operates in an underwater or wet environment, and can be used to guarantee a drying environment inside the instrument, increase the pressure inside the instrument shell and alleviate and prevent continuous immersion of water molecules.
Description
Technical field:
The present invention relates to drier, specifically the application in the instrument and meter of a kind of moistureproof pressure-maintaining drying agent good seal in humidity or underwater environment.
Background technology:
In feedwater water supply industry, the working environment of most of instrument and meter, all in the deep-well that wetness is larger relatively, is even immersed in water.Steam can be seeped in product shell in product long-play process, affects life-span and the runnability of electronic device.
The measure the most widely of present moistureproof way is to add conventional dry drying prescription, DeGrain.Existing desiccant product (1) silica-gel desiccant: main component is silica, processes granular or pearl by natural minerals through purifying.Be used for the storage of instrument, instrument, apparatus, leather, case and bag, footwear, textile, food, medicine etc. and the relative humidity that transportation controls environment, prevent that article from making moist, go mouldy and corrosion; (2) mineral agent drier: adopt pure natural raw mineral materials and active hygroscopic agent refining to form, for the preserved in dry atmosphere of optical instrument, electronic product, medical health care, packaging for foodstuff and war products and the product for civilian use; (3) quick lime drier: be white or linen block; (4) fiber desiccant: formed through special process exquisiteness by pure natural plant fiber, processing technology is complicated, and processing cost is high.
Because the humidity of working environment is relatively large, hydrone content is quite high.And in the housing of instrument and meter, have hardly steam, so can there is water diffusion.In airtight instrument housing, only absorb water vapour, can increase the inside and outside pressure reduction of housing when product is fully immersed in water, the pressure of water is greater than the pressure that in housing, air produces, thereby make hydrone constantly penetrate in housing, conventional dry drying prescription is consumed completely very soon, and increase housing inside and outside differential pressure and form vicious circle, affect the normal work of electronic device.
Summary of the invention:
The present invention is intended to solve that existing drier exists because absorbing the steam penetrating in electronic product casing, increases the problem of the inside and outside pressure reduction of housing, and provide a kind of steam that can either effectively absorb to reach the moistureproof effect dehumidifying, can keep the air pressure in airtight instrument again, effectively stop steam to continue the application in the instrument and meter of moistureproof pressure-maintaining drying agent good seal in humidity or underwater environment of permeating in instrument.
The technical scheme that the present invention solves described problem employing is:
Application in the instrument and meter of a kind of moistureproof pressure-maintaining drying agent good seal in humidity or underwater environment, described moistureproof pressure-maintaining drying agent is comprised of A material and B material, the mass ratio of A material and B material is 1:1-1.5, and A material is the mixture of peroxide or peroxide and superoxides; B material is organic acid.
Described peroxide is potassium peroxide and sodium peroxide a kind of or its mixture wherein.
Described superoxides is potassium superoxide or sodium superoxide or super rubidium oxide or super cesium oxide.
Described organic acid is oxalic acid and citric acid a kind of or its mixture wherein.
The particle diameter of described Peroxides and Superoxides is 0-6mm.
The particle diameter of described oxalic acid and citric acid is 0-8mm.
In technical scheme of the present invention, if use merely sodium peroxide or potassium peroxide still, for the requirement of better adaptation field working conditions, to have added in right amount superoxides to meet moisture effect, make it to emit rapidly oxygen and increase the pressure in instrument and meter.A material belongs to alkalescence, and it is acid that B material belongs to, and if there is water inlet in a large number in unexpected instrument and meter, acid-base neutralization reaction can occur A B material, reduces alkaline harm.
Compared with prior art, advantage of the present invention is: have very strong water absorbing properties, and can discharge nonpoisonous and tasteless oxygen very soon.Maximum can absorb 24% of own wt, discharge 44% oxygen of own wt.After water suction, be white powder, be applicable to be operated under water or moist instrument and meter in, not only guaranteed the environment that instrument internal is dry but also increased the pressure in Instrument shell, alleviate and stop hydrone to continue immersion.
