Abstract
The invention relates to a method for acquiring sequence diagrams of cross sections of a leather sample. The method is characterized by comprising the following steps of dipping the leather sample by using the mixture of epoxy resin and curing agents for fixing leather fibers, and then burnishing and polishing layer by layer and the like, thereby acquiring the sequence diagrams of the cross sections under a microscope. A marker is pre-buried for rectification of the sequence diagrams, and intervals among the sequence diagrams can be determined through measurement of the thickness of a base body, therefore, the method lays the foundation for accurately reflecting the sequence diagrams of the leather fibers in the follow-up treatment.
Description
Technical field
The present invention relates to a kind of method of obtaining sequence of pictures, be specifically related to a kind of method of obtaining leather sample cross section sequence of pictures.
Background technology
Many results of study show: the performance position that rawhide and finished product are removed from office is poor very large, but the change of the intensity position of fibrous bundle difference is little, and this is mainly caused by the woven network difference of fibrous bundle with regard to the poor existence in explanation position.Because before deformation occurs fibrous bundle itself, network of fibers can first occur compared with large deformation.As can be seen here, leather fiber Network Weaving mode is very large on Leather Properties impact, but existing network of fibers research method is mainly to be undertaken by observing the various sections of leather tissue, by a certain cross section of analytical sample, infer the true woven network of leather fiber, there is a lot of uncertainties in this deduction, lacks scientific basis.So need to set up leather 3 D weaving network structure by Three Dimensional Reconfiguration, then 3 D weaving network structure be studied.Set up three-dimensionalreconstruction model, first just need to obtain leather cross section sequence of pictures.Existing method is mainly to use serial section method traditional in histology to carry out, but because leather fiber is intensive, and fiber in section is yielding, disappearance is serious, and section is difficult to continuously.We,, through attempting, successfully test out a kind of leather sample preparation method (ZL201110179680.4) who is applicable to metallography microscope sem observation, but the method are only suitable for observing single cross-sectional image, if want to obtain sequence of pictures, also need other more multi-step.
Summary of the invention
The object of the invention is to overcome above-mentioned prior art not enough, provide a kind of and make that the distortion of leather cross-section fibers is little, continuity is strong, sequence of pictures acquisition methods simple to operate.
summary of the invention
Obtain a method for leather sample cross section sequence of pictures, it is characterized in that using epoxy resin and curing agent mixture dipping leather sample, leather fiber is fixed, then to its successively polish, the operation such as polishing, obtain under the microscope sequence cross section picture.By pre-buried mark, be that sequence of pictures registration is ready, by measuring the thickness of matrix, determine the spacing of sequence of pictures.

(4) the sample piece of step (3) having been polished is put in the middle of two exceptionally straight filiforms, regulate filiform position to make the A of sample piece and B face central authorities be close to filiform, then on sample piece and filiform, evenly drip the resin adhesive liquid that step (1) prepares, filiform is covered by resin completely, wait its spontaneous curing after filiform be fixed on sample piece;
(5) cut off filiform, take off the sample piece in step (4), sample piece two ends are smooth with sand papering, then be vertically fixed in mould, the resin adhesive liquid making to implantation step (1) in mould, solidifies, the demoulding at normal temperatures, obtains the curing rectangle sample piece that middle part is fixed with leather sample;
(6) curing rectangle sample piece step (5) being obtained solidifies 2-3 hour after putting into 60 ℃ of thermostatic drying chambers;
(7) by after each face of rectangle sample piece of being cured polish flat, and relative two sides is parallel, and the one side of observing end with leather is polished to the leather cross section of exposing needs observation with flint glass paper;
(8) gradient polishing is carried out to waterproof abrasive paper in the sample piece cross section of exposing leather observation end in step (7), and after polishing, choose two some x close to from leather sample, y, with micron milscale, measure respectively rectangle sample piece x, the thickness at y point place is then observed the picture that obtains this leather cross section to microscope, first of this sample sequence picture, note choosing the position that has pre-buried label;
(9) the rectangle sample piece cross section of having clapped picture is polished off to needed certain thickness with 3000 order waterproof abrasive paper vertical cross-sections, polishing, with micron milscale, measure respectively rectangle sample piece x, the thickness at y point place (guarantee and step (8) in x, y point be same position) after, to microscope, obtain the second pictures;
(10) repeating step (9), obtains the 3rd pictures, the 4th pictures successively ... thereby, obtain sequence of pictures;
(11) thickness difference that the thickness difference of twice of front and back x being ordered and y are ordered is averaged to count and is made the spacing distance of adjacent two sections (picture), thereby obtains the spacing of sequence of pictures.
The epoxy resin of described step (1) is the epoxy resin that viscosity is low, the transparency is good.
The epoxy hardener of described step (1) is the agent of amine transparent cured.
The leather sample of described step (2) is the leather bar of long 10～20mm, wide 1～2mm.
The filiform of described step (4) is tinsel or macromolecular fibre, its even thickness, and cross section is circular, diameter is less than 30 microns, has certain intensity.
The mould of described step (5) is long 50mm, wide 40mm, high 20mm rectangle tubbiness mould.
Gradient polishing in described step (8) is for using successively 200 orders, 320 orders, 600 orders, 1000 orders, 1500 orders, 2000 orders, 3000 order liquid honings.
In described step (8) and (9), be finished to 100～300 revs/min of buffing machine polishings 1～2 minute.
Beneficial effect
Method of the present invention, owing to having used fixedly leather fiber of epoxy resin gradation embedding, keep the original attitude of leather fiber in woven network completely, by pre-buried two rhizoid shape marks, be that sequence of pictures registration is ready, by measuring the thickness of matrix, determine the interlamellar spacing of sequence of pictures, thereby be that in subsequent treatment, accurate reflection leather fiber braiding structure is laid a solid foundation.In addition, final embedding sample be rectangle can guarantee better each measurement point x, y and the position being placed on microscope example bench identical, because 3000 order sand paper are very thin, can control more accurately the thickness polishing off, be not clamminess in selected epoxy resin cure rear surface, the transparency is good, and set time is adjustable, this has all facilitated operation, has improved accuracy.
