[0004] 2. Arsenic (also known as hoarfrost) is impure arsenic trioxide, the main component is As2O3, which is highly toxic
The use of arsenic to make animal specimens is harmful to the operators, and the storage of specimens pollutes the surrounding air to a certain extent
[0005] 3. Since the fibrous interstitium in the raw hide is basically not removed, the collagen fibers cannot be separated and loosened as they should be, and they have not been deformed through tanning. Make taxidermy shape change a bit

specific Embodiment approach

[0031] The specific embodiment: the specific embodiment of the present invention is described in detail below:

[0032] Prepare the solution:

[0033] 1. Prepare degreasing solution 1: Add 25g~35g salt (30g best) to 1 liter of warm water at 30°C~40°C (best 35°C), mix well with 2-4ml skin degreasing agent and set aside;

[0034] 2: Preparation of degreasing solution 2: Add 3-5 ml of skin degreasing agent per kilogram of water at 30°C~40°C (optimally 35°C), and mix well with 40-50 grams of salt for later use.

[0035] 3. Prepare acidification solution: Add 35-45 grams of salt (40 grams is the best) and 35-45 grams of sodium sulfate (sodium sulfate) into 1 liter of warm water at 30°C~40°C (35°C is the best). 40 grams), sulfuric acid 1ml~1.5ml (1.2ml is the best), formic acid 3-5ml, skin fatliquor 0.8ml~1.2ml (1ml is the best), skin penetration agent 0.8ml~1.2ml (best 1 ml) and mix well, the pH value is 1.0 to 1.5.

[0036] 4. Preparation of neutralization solution: add 4-5...

Embodiment 1

[0038] Embodiment 1: a kind of tanning process of making fur animal specimen, it comprises the steps:

[0039] (1) De-meat treatment:

[0040] 1. Remove the meat and cut the inside:

[0041] Remove the subcutaneous tissue, connective tissue, meat slag, and sarcolemma that are not needed in fur processing from the fresh skin that has just been peeled off the animal carcass, and expose the fibrous tissue of the skin; Scrape off the fat and residual meat attached to the meat surface. In order not to damage the hair roots, you can spread a thick cloth on the log when scraping; the trimming is closely related to the next step of degreasing. If there is a lot of residual fat, it is not conducive to degreasing. The effect of scraping the inside with a bow knife is to squeeze the residual fat inside the skin to the surface of the skin, which is beneficial to degreasing.

[0042] 2. Cleaning the skins:

[0043] Wash with clean water or a small amount of skin degreasing agent unt...

Embodiment 2

[0068] Embodiment 2: A kind of tanning process for making fur animal specimens, its steps are basically the same as in Embodiment 1, the difference is that it removes the fifth step of degreasing step, for example, animals with long horns do not need after the fourth step of skin peeling step Skim and proceed directly to the neutralization step. (Animals with long horns are herbivores and have less fat, which can be easily removed during pickling).

Abstract

The invention discloses a tanning process for making a fur-bearing animal specimen. The tanning process comprises the steps of removing meat from a fresh hide which is just peeled off from an animal carcass, shaving and cleaning the hide and then draining off excessive moisture, dipping in a degreasing solution for degreasing, washing with warm water and throwing away moisture on the hide, dipping in an acidizing fluid for pickling, evenly shaving the hide and dipping the hide in a neutralizing solution for neutralization, putting in a tanning agent for tanning for 12-24 hours, regulating alkali 1 hour later after the hide is put in, regulating alkali by one gram at a time and total three times at an interval of 2 hours, and stabilizing the final pH within the range from 3.5 to 4.0 and finishing tanning. The hide plate tanned by the tanning process is light, soft, white and good in extensibility; the fur is loose and soft, and bright; the hair of the animal is permanently fixed on the leather which is high in tensile strength; and the animal specimen is easier to fur and sew, and also is resistant to corrosion, mothproof, shrinkage-proof, deformation-proof, and environment-friendly.

Description

Technical field: [0001] The invention relates to a tanning process for making fur animal specimens, and belongs to the technical field of tanning. Background technique: [0002] The tanning of hides is to use chemical agents and physical methods to remove the fat, muscle tissue, water, etc. attached to the hides, so that the retained fibers become soft, soft, dehydrated and prevent bacterial corruption. Tanning can generate cross-linking bonds between the polypeptide bonds of skin collagen, increase the stability of collagen structure, increase the shrinkage temperature and the stability of moisture and heat resistance, and improve the ability to resist acids, alkalis, enzymes and other chemicals. After tanning, the fibers of the hide and the tanning agent form a permanent, stable, and irreversible bond, so as to meet the requirements for making specimens—gloss, suppleness, bright colors, elasticity without shrinkage and deformation. At present, most of the tanning techniqu...
