Abstract

The invention relates to an elephant skin processing method for making a posture specimen of an Asian elephant. That is: add penetrant and normal temperature water to the drum for 20 minutes, wash with water, add penetrant and bleaching powder for 30 minutes, drain the water, add water and industrial salt, and turn for 10 minutes; dilute with formic acid and add In the drum, turn for 20 minutes; dilute with sulfuric acid water and add to the drum twice, each time for 20 minutes; Formaldehyde water is released; chromium powder is added to the drum and mixed with water until the drum is full for 3 hours, and left to stand for 24 hours; sodium formate is diluted and added to the drum for 2 hours; after baking soda is diluted, it is added to the drum in 4 times, each time Rotate for 20 minutes, stand still for 24 hours, and then take out the drum; apply arsenic paste evenly on the inside of the elephant skin to obtain the elephant skin for making specimens. The elephant skin treated by this method is soft, basically does not change color, is easy to adjust the posture, and still has a certain degree of elasticity after drying.

Description

Elephant skin processing methods for making Asian elephant pose specimens

technical field

The invention relates to the technical field of making animal specimens, in particular to an elephant skin processing method for making Asian elephant posture specimens.

Background technique

The production of large animal specimens has always been carried out by stuffing. There is no set of scientific methods for the treatment of elephant skins. The board, the color is not correct, inelastic, and the posture is not good, so it cannot be made into a specimen that conforms to the natural posture. As a result, the production of large animal specimens in China is at a relatively low level.

Contents of the invention

The purpose of the present invention is to overcome the deficiencies in the prior art, and provide a method for processing elephant skin for making Asian elephant posture specimens. The elephant skin treated by this method is soft, does not change color basically, is easy to adjust the posture, and still has the appearance after drying. Certain elasticity has reached the purpose that the processed elephant skin can be used for posture specimen making and long-term preservation.

The invention uses water to remove impurities on the surface of elephant skin, acid and salt to remove grease, and at the same time makes the skin soft, and heavy metals make the skin tissue and heavy metal particles react to form complexes, which can prevent insects from biting and microbial invasion, and the rotation of the drum can The contact between various solutions and the skin is uniform, and at the same time, the fibers in the elephant skin can be twisted, so that the elephant skin can be shaped freely during production.

Specific processing methods and procedures:

1. Put the elephant skin into the drum after weighing;

2. Add 1-3% penetrating agent (1-3% aqueous solution of alkylphenol polyoxyethylene ether, pH = 5.0-7.0) and 200% normal temperature water to the drum, let the drum rotate for 20 minutes , forward rotation and reverse rotation each take half of the time;

3. Drain the water in the drum, wash the fur with running water, and turn the drum while washing until the water is clear;

4. Change the water in the drum to warm water at 35°C. The volume of warm water is 200% of the fur, and then add 1-3% penetrating agent (1-3% aqueous solution of alkylphenol polyoxyethylene ether, pH value=5.0～7.0) and 0.2～1% bleaching powder, turn for about 30 minutes, when the leather is completely softened, turn for about 30 minutes;

5. Add normal temperature water, lower the temperature of the skin to normal temperature, and rinse until the water is clear (about 30 minutes);

6. After draining the water in the drum, add 80% of the volume of the drum at room temperature and 8-10% of industrial salt (commercially available), and rotate for about 10 minutes to make the industrial salt evenly adhere to the elephant skin;

7. Dilute formic acid with 0.8-2% of the weight of elephant skin with 20 times of water, add it to the drum, and rotate for about 20 minutes;

8. Dilute the sulfuric acid with 1.1-2% of the weight of the elephant skin with 20 times of water and add it into the drum twice, and rotate for about 20 minutes each time;

9. Turn it for about 1 hour and 30 minutes, and then let it stand overnight;

10. When the pH value of the solution in the drum is about 2.2, let the acid penetrate the elephant skin (if the acid is not soaked, you can properly extend the drum rotation time until it penetrates);

11. Dilute 1.7-3% formaldehyde of elephant skin with water 20 times and add it to the drum, turn it for 1 hour and let it stand for about 24 hours, then release the formaldehyde water from the drum;

12. Add chromium powder with 6-8% weight of elephant skin into the drum, add water until the drum is full, turn it for about 3 hours, and let it stand for about 24 hours;

13. Dilute 1-3% of the weight of elephant skin with water (concentration: 10%) and add sodium formate into the drum, and rotate for about 2 hours;

14. Dilute the baking soda with 1.6-3% weight of elephant skin with 20 times of water and add it into the drum in 4 times, and rotate for 20 minutes each time, and start to test the pH value with precision test paper for the second time. When the pH reaches At about 3.9, stop adding, turn for about 2 hours, and leave the drum after standing for 24 hours;

15. Shave the elephant skin manually or mechanically to a thickness of about 5 mm;

16. Use 100-200 grams of arsenic, 1,000-1,500 grams of soap, 1,000-2,000 grams of alum, and 1,000-2,000 grams of camphor to make arsenic paste (the preparation method is: add soap and alum to 5,000-5,500 grams of water to make a paste When it cools down to about 25 degrees Celsius, add camphor dissolved in alcohol, stir and then add arsenic, stir slowly and let stand until completely cooled) Apply evenly on the inside of the elephant skin, that is, the treated one can be used to make specimens ( Asian elephant) elephant skin.

The present invention has explored and created this cover method according to the characteristic of elephant skin and the desired characteristic. This method is easy to operate, standardized and quantified. The elephant skin treated by this method is soft, basically does not change color, easy to adjust the posture, and still has a certain elasticity after drying, reaching the level that the processed elephant skin can be used for making posture specimens. and long-term storage purposes.
