Abstract
A method for preparing a thin slice for carrying a loose friable rock sample includes the following steps: (1) the sample by hand is crushed; (2) the crushed sample rags is dried; (3) the dried and crushed sample is arranged in a container and is saturated by coarse glue which can be a resin glue diluted by an organic solvent or a liquid synthesized glue with smaller viscosity like the 502 glue; (4) the sample is dried at low temperature, solidified and prepared into a sample block with the thickness that is not less than 4mm; the 'low temperature' refer to temperature higher than the room temperature and lower than a softening temperature of the coarse glue; (5) one side of the sample block is rubbed down and burnished; (6) the grain side of the sample is stuck on a slide;(7) the sample is ground on the slide into the needed thickness through crude grinding and fine grinding successively under the situation of carrying out microscope checking ceaselessly. The method overcomes the difficulty during a slide preparing process that the coarse glue can not immerge into the loose friable rock sample and successfully solidifies the loose sample and makes into the thin slice.
Description
Technical field
The present invention relates to a kind of preparation of specimen method, be specifically related to a kind of method for making of crumbly rock sample slide glass.
Background technology
In a lot of subjects such as geology, mineralogy, petrifactology, all need to make the thin slice that carries of rock or collection of fossils.Its method is the thin slice that sample is cut into several millimeters thick, and it is simultaneously polished polishing, with glue this light face is sticked on the slide, successively through corase grind, fine grinding, is constantly carrying out under the situation of microexamination, the sample on the slide is ground to the thickness that needs.Used glue have sex change abies balsam, Canada balsam or other colourless, transparent, do not produce crystallization and the satisfactory glue of index of refraction.The very loose sample of one class is arranged in sample, can't cut into thin slice, the sample that wherein has even can not soak.For this class sample, traditional handicraft is to carry out glue earlier to soak processing before section, is also referred to as and boils glue, method is that sample is put into the resin glue of using organic solvent diluting, heating makes glue be immersed in sample inside, sample can be solidified (and playing waterproof action) after the cooling; Perhaps use the less liquid rubber polymer of viscosity, 502 glue for example, solidify, more then by the classic method film-making dipping specimen.But these boil the film-making problem that gluing method can not solve all loose samples fully, for example, mud stone that has or sample of sandstone oil-containing or contain alkali, glue can't immerse sample inside, and the sample that also has is " diffusing and not loose ", and the slit is very little but pulverizes easily, glue also can't immerse, even also can not soak with 502 fully liquid glue, do not play solidification, so just be difficult to make qualified petrographic thin section yet.
Summary of the invention
At the above-mentioned problems in the prior art, the purpose of this invention is to provide the method for making that a kind of loose sample carries thin slice, this method can overcome the difficulty that loose frangible sample that glue can't immerse runs in the film-making operation, smoothly loose sample is solidified and be made into thin slice.
The scheme of finishing the foregoing invention task is: a kind of method for making of crumbly rock sample slide glass is characterized in that step is as follows:
(1), by hand sample is crushed;
(2), the broken foam oven dry of the sample of crushing;
(3), the broken foam of sample of oven dry is placed on soaks into glue in the container; Described glue can be the resin glue of organic solvent diluting; Or the less liquid rubber polymer of viscosity, for example 502 glue;
(4), with low temperature sample is dried again, solidify, make the casting that thickness is not less than 4mm; Described " low temperature " is meant: be higher than room temperature, and be lower than the softening temperature of glue;
(5), the one side with this casting polishes polishing;
(6), stick on the slide with the light face of glue sample;
(7), successively pass through corase grind, fine grinding, constantly carrying out under the situation of microexamination, the sample on the slide is ground to the thickness that needs.
Said method can comprise that oil-containing contains alkali sample impregnation and solidifies with the loose frangible sample that can not soak into glue, and makes and carry a thin slice.But because this method has been destroyed the original structure of sample,, can only in a part of research work, use, for example can be used for the film-making of simple mineral research sample, and can not be used for all loose frangible samples so bigger limitation is also arranged.
The present invention has following prioritization scheme:
1, after (5) step, if the plane that grinds is still crude, can't polish, then increase following steps:
(5)-1, on the surface that polishes, carry out a glue again and soak into, use low temperature drying again, solidify;
Requiring of step (5)-1 and step (3), (4) is identical: described glue can be the resin glue of organic solvent diluting; Or the less liquid rubber polymer of viscosity, for example 502 glue.
When 2, (6) step sticks on the slide, soak into employing with a kind of glue to sample with (3) step glue; The difficulty of stickup can be reduced, and the optical quality of thin slice can be improved.
3, (4) step low temperature drying, when solidifying sample, vibrate.
That is, the container of placing the broken foam of sample is placed on oven dry on the Vib., curing; Or dry, when solidifying, container constantly beaten gently with glass bar.The vibration measure can make the tightr of sample broken end curing.
4, " the light face of sample is sticked on the slide " before in (6) step, increases following steps:
(6)-and a, the one side sanding (sample sticks on the sanding face) that will carry glass with 180# sand.
It is transparent fully that glue during stickup can make frosted glass become, so this step can guarantee the flatness of slide surface, and increase the bonding dynamics of sample and slide, when the sample wear down of stickup on it to the end during the stage, can guarantee that the thickness of thin slice each several part is even.
5, in the corase grind of (7) step, fine grinding, note at any time can not coming unstuck between sample and the slide, if come unstuck then increase following steps:
(7)-1 pair position of coming unstuck reinforces with glue at any time, in order to avoid influence the flatness of sample.
The present invention has overcome the difficulty that glue can't immerse in the prior art loose frangible sample runs in the film-making operation, smoothly loose sample is solidified and be made into thin slice.
Embodiment
Embodiment 1,
Loose friable rock sample (for example: gypseous evaporitic rock or contain pozzuolanic bentonite) carries the method for making of thin slice, and step is:
