Problems solved by technology

The dermis of large marine mammals such as whales and walruses is thicker (several times thicker than ordinary animal leather), the collagen fibers are thick, and the fat content is much higher than that of ordinary cowhide and pigskin. The traditional method does not remove grease, and the specimens made are easy to Occurrence of oil spill corruption, shrinkage deformation, insect tearing and other phenomena of hides
It not only affects the appearance and preservation life of the specimens, but also causes potential health hazards to visitors due to the smell of corruption and arsenic trioxide powder
[0003] In order to overcome the shortcomings of the existing large marine mammal skins such as endless degreasing, easy corruption of specimens and shrinkage deformation, the present invention provides a new degreasing method, which can not only remove about 85% of the fat in the skins, The fat content is greatly reduced, and the harmless antiseptic effect can be well achieved

Embodiment Construction

[0023] Site setup: Choose an appropriate size pool based on the size of the large marine mammals being handled.

[0024] The chrome tanning agent used in the examples is a trivalent basic chrome sulfate tanning agent / tanning liquor with an alkalinity of 33%. The preparation method is as follows: after mixing sodium dichromate and sulfuric acid solution, reduce it with a sulfuric acid solution containing glucose , and remove the sodium sulfate.

[0025] Deliming aid EZE and acrylic resin retanning agent are products of Shanghai Leather Chemical Factory.

[0026] The skins of large marine mammals such as whales and walruses are peeled off, the remaining muscle on the skin is removed mechanically, and samples are taken from the abdomen and chest of the skin, and then the following treatments are performed:

[0027] 1. Soaking in water: Soak the skin in the aqueous solution of alkylphenol polyoxyethylene ether (or polyether nonionic surfactant) and sodium hypochlorite with pH=10,...

Abstract

The invention relates to technologies for manufacturing large marine mammal skinned specimens and discloses a novel method for degreasing hides of large marine mammals, such as whales. The method comprises the steps of soaking, degreasing, liming, deliming, softening, pickling, tanning and retanning. According to the method, a degreasing operation runs through a whole hide tanning process; and adipose tissues can be removed from the hides greatly, a tanning agent is used for replacing soluble protein in skin and undertakes a medium of a connection structure, the stability of a collagen structure is improved, and the shrinkage temperature and hydrothermal resisting stability are improved, so that the aims of no oil spill corruption, no contraction distortion, long-term storage and healthy exhibition are achieved.

Description

technical field [0001] The invention relates to a technique for making specimens of large marine mammals, in particular to a new method for degreasing the hides of large cetaceans. Background technique [0002] At present, animal taxidermy hides are mainly degreased and preserved through mechanical de-fleshing, soaking in alcohol, and applying a mixture of arsenic trioxide, alum, soap, and camphor. The dermis of large marine mammals such as whales and walruses is thicker (several times thicker than ordinary animal leather), the collagen fibers are thick, and the fat content is much higher than that of ordinary cowhide and pigskin. The traditional method does not remove grease, and the specimens made are easy to Occurrence of skin oil spill corruption, shrinkage deformation, insect tear damage and other phenomena. It not only affects the aesthetics and preservation life of the specimens, but also causes potential health hazards to visitors due to the smell of corruption and ...
