Abstract
The utility model relates to a manufacture method for test samples, in particular to a manufacture method for test samples, which comprises the steps of mould manufacturing, resin melting, rock sample fusing, and mould polishing. The manufacture method for test samples can solve the problem that a plurality of special rocks are hard to sample completely; in the way, test can be implemented by using a plurality of very small rocks. Secondarily, materials can be sufficiently used by the manufacture method; rock blocks or rock debris remained by mining can be used; and for certain expensive minerals, the advantage of the manufacture method can be obviously shown. In addition, compared with a traditional method, the manufacture method has quick sample manufacture speed, and is more practical, simpler and convenient.
Description
Technical field
The present invention relates to a kind of method for making of test specimen, relate in particular to a kind of method for making of rock sample.
Background technology
In traditional Geotechnical Engineering detected, the making of sample was a complexity and requisite process always.Rock sample is from exploiting polishing, and to being put on the testing table, this has all passed through the work of a series of complexity again.For some rare rocks, and compare fragmented rock, be difficult to get the rock of monoblock.Can't collect enough samples like this and directly cause can't carrying out of test.
In addition, in traditional rock basic mechanical characteristic measurement, use relatively large rock more, it is processed into is applicable to Instrument measuring then.And along with the development of modern measuring technology, especially be the appearance of the new test method of representative with miniature feeler inspection (Point Load Tests, micro-indentations test), the size restriction of rock sample reduces gradually, only needs well-regulated shape to test for sample.But for the small blocks rock, processing that the shape that makes it formation rule is used to test is a very thing of trouble.
For this reason, the present invention has overcome all inconvenience of rock in making the sample process, the character of utilizing resin when normal temperature, to solidify, little sillar or landwaste are fixed in the resin, and then resin begin from two ends the polishing polish, the shiny surface of sillar is exposed in appearance, makes it to be applied to the method for rock mechanics experiment.
Epoxy resin is the macromolecular compound that contains epoxide group in a kind of molecular structure, epoxy resin after the curing has good physical and chemical performance, it has excellent bonding strength to the surface of metal and nonmetallic materials, and dielectric properties are good, and the set shrinkage factor is little, the product size good stability, the hardness height, pliability is better, to alkali and most of solvent-stable, thereby be widely used in national defence, national economy all departments, make purposes such as cast, dipping, lamination material, bonding agent, coating.
Summary of the invention
The objective of the invention is to have overcome deficiency of the prior art, provide a kind of and can make full use of material, the irregular rock of fritter even landwaste are processed into a kind of method of sample.
The present invention adopts following technical scheme
1, a kind of method for making of rock sample: step is as follows,
1), makes corresponding mould according to the size of rock sample;
2), resin is melted;
3), put into the mould of step 1, again the crushed rocks sample is put into mould and combine with liquid resin with being melted into liquid resin in the step 2;
4), after the resin in the waiting step 3 fully solidifies, sample is taken out;
5), the sample after the above-mentioned taking-up is polished, the surface of rock is exposed, promptly finish the making of this sample.
The method for making of a kind of rock sample of the present invention is characterized in that: add amine curing agent in the resin in the described step 2 after thawing.
The method for making of a kind of rock sample of the present invention is characterized in that: the volume ratio of described resin and rock sample is 2:1.
The method for making of a kind of rock sample of the present invention is characterized in that: described resin is an epoxy resin.
Beneficial effect
The present invention can solve the problem that the rock of some Special Category is difficult to complete sampling, like this, only needs several very little rocks just can test.Secondly, the present invention can make full use of material, can utilize exploitation discarded remaining sillar or landwaste, and for some Valuable Minerals, advantage of the present invention just can clearly show.In addition, method of the present invention is compared with classic method, and the speed of sample preparation is fast, more practical simplicity.
