Detailed description of the invention
Hereinafter, the glass bar and the making and use method thereof that prevent liquid bumping of exemplary embodiment of the present will be specifically described.
When liquid bottom heats, boiling steam bubble rises to liquid surface and escapes the process of going from liquid bottom, except must overcoming atmospheric pressure suffered on liquid level, also must overcome the hydrostatic pressure between liquid level to boiling steam bubble nidus, the more important thing is simultaneously and must overcome the surface tension of liquid to bubble.Any bubble in a liquid is all subject to the surface tension of liquid, and surface tension forces the surface area of this bubble to diminish, and the surface tension that therefore inside of bubble must have enough large pressure to overcome liquid just can be present in liquid.And capillary size suffered by bubble in liquid is different from the surface tension characteristics of liquid and Air Bubble Size, its relational expression is as follows: P=15 × 10
-4γ/R, wherein P is pressure, and R is bubble radius, and γ is the surface tension of liquid.Less according to the radius of the known bubble of above-mentioned formula, overcome capillary vapour pressure needed for it larger, when bubble radius level off to zero time, capillary vapour pressure approach infinity need be overcome.Theoretical according to this, be produce a new bubble zero from radius, needed for overcome capillary vapour pressure very big, may directly produce new bubble hardly.But in fact; often there is air in liquid or adsorbed the air of the particulate of air or the coarse absorption because of liquid container wall; although the radius of these bubbles is very little; but boiling steam bubble just starts to be formed with the bubble of this radius, and like this, the capillary vapour pressure overcome needed for bubble reduces greatly; when fluid temperature is superheated to a certain degree and vapour pressure enough overcomes all resistances; steam bubble just with these trickle air bubbles for core, start constantly to grow up risings, so boiling just constantly generation.But this type of boiling is often irregular, can not realize steady boiling.Further, due to the overheated of liquid and the surface tension effects of liquid to the boiling steam bubble produced, make the liquid reaching boiling point not produce bubble, once vibration or applying external force, suddenly produce the boiling of a large amount of bubble and cause liquid bumping.Therefore, in order to prevent liquid bumping and realize steadily boiling, need ensure that liquid just can produce bubble reposefully before boiling.
In order to make to obtain more absorbed air in liquid and ensure that liquid steadily seethes with excitement at the boiling point, two step etch is carried out and an one-step physical grinding process makes glass bar have coarse surface by the simple glass commonly used laboratory rod, after anti-bumping glass bar immersed heating in liquid, anti-bumping glass bar also can form a lot of minute bubbles by absorbed air more in a liquid, minute bubbles and then core bubble when becoming boiling, thus before liquid all seethes with excitement, just a large amount of bubble is produced from liquid bottom, thus effectively prevent the generation of bumping phenomenon.
Particularly, prevent the preparation method of the glass bar of liquid bumping from comprising the following steps according to an exemplary embodiment of the present invention;
steps A:
Get the glass bar of clean dried, at the surface of glass bar parcel paraffin layer, then engrave at a cephalic par place of glass bar and mark and remove the paraffin of mark.
This step is for first time chemical attack process is afterwards prepared, and namely first carries out pretreatment to glass bar.Because liquid is generally bottom-heated, bottom is often overheated, first bubble can produce in bottom, therefore must strengthen hole process of the immersion of glass bar liquid bottom to be heated and make its surface more coarse, but need to ensure that glass bar has some strength and is convenient to easy processing simultaneously.
The application specifically engraves mark at a cephalic par of glass bar and by the portion envelops paraffin layer on glass bar except marking, and then carries out follow-up process.Wherein, paraffin layer the part on cover glass rod except mark can not be corroded and is only corroded in second time chemical attack in the process of first time chemical attack; part in mark then can form the hole darker than the part on glass bar except mark by first time chemical attack and second time chemical attack, and concrete corrosion step is as described below.Wherein, what also paraffin can be replaced by that other does not react with corrosive liquid can cold melt sealing substance.
Preferably, be engraved in the indenture being labeled as band straight-line groove at glass bar one cephalic par place, the bubble of liquid bottom produces that resistance is less and processing that is mark is portrayed comparatively simple thus, such as, can be cross mark or rice word mark etc., but the present invention is not limited thereto.
step B:
The glass bar of steps A gained is immersed in the first corrosive liquid, soak after 5 ~ 60 minutes and take out, peel off paraffin layer and clean.
This step is first time chemical attack, and after the immersion of the first corrosive liquid, the part on glass bar in mark is once corroded and forms hole, and the part on glass bar except mark is not corroded due to the protection of paraffin layer.
Wherein, the first corrosive liquid is mixed according to the volume ratio of 1:1 ~ 1:10 by hydrofluoric acid and watery hydrochloric acid, and watery hydrochloric acid is mixed according to the volume ratio of 1:3 by concentrated hydrochloric acid and water.Preferably, the first corrosive liquid is mixed according to the volume ratio of 1:2 by hydrofluoric acid and watery hydrochloric acid.Hydrochloric acid in first corrosive liquid is reductive acid, can improve acidity and play slowly corrosion.
step C:
The glass bar of step B gained is immersed in the second corrosive liquid, soak and to take out after 5 ~ 30 minutes and to clean.
This step is second time chemical attack, and after the immersion of the second corrosive liquid, the part on glass bar in mark is by anticaustic and form darker hole, and the part on glass bar except marking also is corroded formation hole.
Wherein, the second corrosive liquid is mixed according to the volume ratio of 1:1 ~ 1:10 by hydrofluoric acid and dilute sulfuric acid, and dilute sulfuric acid is mixed according to the volume ratio of 1:4 by the concentrated sulfuric acid and water.Preferably, the second corrosive liquid is mixed according to the volume ratio of 1:10 by hydrofluoric acid and dilute sulfuric acid.Sulfuric acid in second corrosive liquid is oxidizing acid, can improve acidity and play homogeneous corrosion.
Because the glass bar of use for laboratory is except anti-bumping, also there is the function such as agitated liquid and transfer liquid, thus make it reach certain roughness and under having the prerequisite of anti-bumping effect at etching glass rod, also need to ensure the intensity of glass bar and avoid because glass bar surface pore is too large and cause when transfer liquid and analyze detection material and cannot wash problem residual to the greatest extent.So, concrete selection has been carried out to first time chemical attack and the second time corrosive liquid of chemical attack, soak time, if soak time may cause the anti-bumping effect of glass bar bad not, if soak time is oversize, glass bar insufficient strength or hole may be caused to affect too greatly other function of glass bar.
step D:
The glass bar of step C gained polished at least one polishing scratch along the length direction of glass bar, cleans, dryly then obtain the glass bar preventing liquid bumping.
This step is physics grinding process, mainly in order to increase the surface roughness of glass bar further, makes polishing scratch the generation of bubble then can be made more even along the length direction of glass bar.Preferably, polishing scratch is four and four polishing scratch are parallel to each other along the length direction of glass bar, can take into account stirring and the transfer liquid function of glass bar thus.
According to the present invention, handled pristine glass rod is at least siliceous glass bar, the such as glass bar of silicon boron glass rod or siliceous not boracic, to ensure that the first corrosive liquid and the second corrosive liquid are to the corrosive effect of glass bar.Further, the diameter of glass bar at more than 8mm, such as 8-10mm; When an oblique cutting of glass bar enter to hold the container until boiling liquid and support to hold until the container side wall of boiling liquid and the intersection of diapire and other end by being put in the vessel port place held until boiling liquid time, to grow, glass bar treats that the vessel port 60-80mm of boiling liquid is advisable.
Mention before, because the glass bar of use for laboratory also has the function such as agitated liquid and transfer liquid except anti-bumping, thus also need the intensity of guarantee glass bar and avoid glass bar surface pore too large.In order to effectively ensure the intensity of glass bar and avoid hole too large, only a part for glass bar is processed in another embodiment of the present invention, particularly:
In stepb, the liquid level of the first corrosive liquid is 10-30mm, the glass bar of steps A gained is carved in markd immersion first corrosive liquid with it and corrodes, wherein, the parcel height of the paraffin layer on the glass bar of steps A gained immerses more than the height 20mm in the first corrosive liquid higher than the glass bar of steps A gained.Thus achieve a corrosion treatmentCorrosion Science to markd one of the quarter of glass bar.
In step C, the glass bar of step B gained is carved markd one with it immerse in the second corrosive liquid, and the glass bar of the step B gained height immersed in the second corrosive liquid be when an oblique cutting of glass bar enter to hold container until boiling liquid and to hold until the container side wall of boiling liquid and the intersection of diapire and other end by being put in the 1/2-3/4 treating the subsurface glass bar length of boiling liquid during the vessel port place held until boiling liquid.Also namely need the height glass bar of step B gained being immersed the second corrosive liquid to be immerse according to glass bar the maximum volume holding the liquid in containers treating boiling liquid to determine, the glass bar height immersed in the second corrosive liquid of the step B gained more than determined enough has ensured the anti-bumping effect of glass bar.
In step D, polishing scratch starts from the corrosion region of the glass bar of step C gained and the boundary line place of non-corrosion region and mark finally, and preferably, polishing scratch is four and four polishing scratch are parallel to each other along the length direction of glass bar.
According to above step, glass bar is divided into corrosion region and non-corrosion region two parts, effectively ensure that intensity and the surface quality of glass bar thus, makes glass bar both may be used for preventing liquid bumping, also can use as simple glass rod.
The glass bar of liquid bumping that prevents of the present invention is then make acquisition according to the above-mentioned preparation method of the glass bar of liquid bumping that prevents.The using method of the glass bar of liquid bumping that prevents of the present invention specifically prevents from the glass bar of liquid bumping from carving markd insertion with it holding in the container treating boiling liquid and by the other end of the glass bar preventing liquid bumping and lean in holding the vessel port place treating boiling liquid by above-mentioned, and then boiling liquid is treated in heating.
