Embodiment 1
[0025] Example 1 Yellow flower specimen
[0026] Tipype in the refrigerator in the water to make the specimen, but it should be carried out in a fish specimen.
[0027] 1, fish condition fixation: use the filter paper to dry the surface, and unfold the drying area of the fins and other folded regions, apply the UV resin glue (UV glue) to the unfolded fish fin area and use the UV lamp to illuminate 30s, so that the UV glue Solidifying the fins, using the same method to unfold all the fish fins (including the fish tail) with UV glue, and then applying the fish with a UV resin glue with a brush and placed UV glue.
[0028] 2, epoxy resin seal: the fish filled with UV glue with α-cyanoacrylate adhesive adhesive to the bottom surface of the silicone mold, and then the A glue (epoxy) B glue (polyether) Amine D-230), AB glue mass ratio is 2.5: 1, stir mixed to no bristles, place the mixed liquid in an oven for 30 minutes, then pour it into the mold of lam, stand to be mixed Subsequent ...
Embodiment 2
[0032] Example 2: Daruto six-wire fish specimen
[0033] Put the cultured live Dabi six fish in sealing the storage box, and then freeze half an hour in the -28 ° C refrigerator, and take it out of the water to perform the thaw, and then produce it.
[0034] 1. Fish status. Delicate the six-wire fish to dry the surface, and expand the folded area of the fish fin to suck the moisture, apply UV resin to the unfolded fish fin area and use the UV lamp to illuminate 30s, so that the UV glue is solidified to fix the fish fin, use The same method unfoldes all the fatches (including the fish tail) and fixed with UV glue, and then applying the fish with a brush to the UV resin glue, which is placed under the UV lamp to solidify.
[0035] 2. Epoxy resin is sealed. The fish seal with UV glue with alpha-cyanoacrylate adhesive to the bottom surface of the silicone mold, and then the A glue (epoxy resin) B glue of the mixed collapse (polyether amine D-230), AB The glue mass ratio was 3: 1, st...

Abstract
The invention provides a fish specimen making method, which comprises the following steps of: absorbing water on the surface of a fish to be subjected to specimen preparation, coating a UV epoxy resin adhesive on the fish body, and solidifying the epoxy resin after ultraviolet radiation; putting the treated fish into a mold, dissolving a mixed solution of epoxy resin and polyether amine D-230, and adding the dissolved mixed solution into the mold, wherein the adding amount of the mixed solution is controlled so that the fish body is not completely covered; then standing and solidifying; carrying out high-temperature sterilization on the solidified specimen, cooling, pouring a mixed solution of epoxy resin and polyether amine D-230 into the mold in which the fish is placed, solidifying, and demolding; and coating UV epoxy resin adhesive on the demolded fish body specimen, and performing ultraviolet irradiation curing to complete the preparation of the specimen. According to the method, the safety of materials used in the actual operation process is high, the sterilization method used in the method is high-pressure steam sterilization and is green and free of pollution, and a formaldehyde solution is adopted in the sterilization method for dipping the specimen, is volatile and has toxicity, carcinogenicity and mutagenicity.
Description
Technical field [0001] The present invention relates to a method of fabricating a fish specimen, and can be used in the preservation of various fish, especially endangered fish species. Background technique [0002] There are two commonly used specimens of fish, one is a impregnation specimen, cleans the specimen, and subtraction after formation, soaking with the drug, the potion used is usually formalin (40% formaldehyde) Solution), alcohol or salt. Although the wine soaking specimen is generally adopted, but due to alcohol degreasing, glue capacity can be strong, affecting the quality of the specimen, so it is usually impregnated with the specimens of formalin. However, the impregnation specimens can easily result in the decolorization of the specimen, and the specimen impregnation liquid is often replaced for the preservation of the sample. Because formaldehyde is poisonous, mutagenic, carcinogenic, is certain in operation and preservation, and the impregnation specimens are n...
