Embodiment 1

[0025] A kind of preparation method of adult otter specimen, its specific preparation steps are:

[0026] Step 1, use distilled water to make detergent or washing powder into a detergent or detergent aqueous solution with a mass concentration of 22%; use distilled water to make sodium carbonate into a pH value of 7.3 and a mass concentration of 1.5% sodium carbonate solution; The mass ratio of boric acid, alum and camphor is 6:3:2 to prepare boric acid anti-corrosion powder; according to the mass ratio of 100:2, take silica gel and curing agent, stir evenly, and prepare mold silica gel with a hardness of 42 degrees, and set aside;

[0027]Step 2. After choosing anesthesia, fix the corpse of the dead otter with cardiac perfusion; use surgical scissors to cut small openings with a diameter of 1 cm on the inside of the forearm joint and hind limb tarsal joint, and then cut the otter fur from the inside of the small opening to the front of the anus ; Then separate the otter fur, a...

Abstract

The invention relates to a manufacturing method of an adult otter specimen. According to the method, a fur of a carcass of an otter is peeled completely; gypsum powders are scattered at the inner and outer sides of the peeled fur to dry the fur; the dried fur is added into a liquid detergent aqueous solution for immersing and after the fur is scrubbed for cleaning, a sodium carbonate solution is applied to the inner and outer sides of the fur and reaction time lasts 2 to 5 hours, and then a boric acid antiseptin is applied to the inner side of the fur to carry out antiseptic treatment; the adult otter carcass with the fur peeled is placed into a gypsum paste to obtain a gypsum mould; a paste is injected through a sprue gate and after drying in the shade again, a gypsum prosthesis is obtained; the gypsum prosthesis is trimmed, wherein the distance between the outer surface of the gypsum prosthesis and the inner wall of the gypsum mould is 1.5 to 1.8 centimeters; a mould silica gel is injected into the gypsum mould so as to obtain a hollow silica gel prosthesis; the processed fur coats the hollow silica gel prosthesis so as to obtain an otter prosthesis; and after being organized, the otter prosthesis is fixed at a wood seat board, so that an adult otter specimen is prepared. The manufacturing method is simple and the cost is low. The prepared specimen has no pungent odor and can be preserved easily; and the structure of the specimen is complete and beautiful.

Description

technical field [0001] The invention relates to a method for preparing a specimen, in particular to a method for preparing an adult otter specimen. Background technique [0002] Animal specimens are essential objects for taxonomic research, exhibitions, popular science education and school teaching. They are also natural cultural heritage, physical evidence for the study of natural changes, and can also be used as scientific research, teaching, and popularization of scientific and technological knowledge. important reference. The irreplaceable scientific value, ornamental value and collection value contained in animal and tissue specimens are entering the family like other works of art and becoming new indoor decorations for people. [0003] A well-made specimen not only brings people knowledge, but also brings people artistic enjoyment. A perfect taxidermy is not only a vivid practical teaching aid, but also a superb work of art. It represents a university, the developme...
