Embodiment 1
[0028] (1) Adjust the pH of the softened skin to about 6.9, and squeeze the water; through the water squeezing process, the total amount of dehydration in the subsequent dehydration process is reduced, and the dehydration efficiency is improved;
[0029] (2) Put the above-mentioned squeezed skin into the rotatable sealing device, add absolute ethanol with a tare weight of 400%, recover the bath liquid after rotating for 120 minutes, and then add ethanol for the second dehydration; rotate the device to make the skin bend , Produce a beating effect, which is conducive to the penetration of materials and speed up the dehydration process; according to the water content in the skin, in the second stage of dehydration, the amount of dehydration can be increased by increasing the amount of solution, and the dehydration speed can be accelerated;
[0030](3) Configure a mixed solution of acetone and absolute ethanol, the ratio of acetone and ethanol is 1:1, add the mixed solution with a...
Embodiment 2
[0042] (1) Adjust the pH of the softened skin to about 6.9, and squeeze the water;
[0043] (2) Add the above-mentioned squeezed skin into the rotatable sealing device, add absolute ethanol with a tare weight of 200%, recover the bath liquid after rotating for 240 minutes, and then add ethanol for the second, third and fourth dehydration;
[0044] (3) Configure the mixed solution of acetone and isopropanol, the ratio of acetone and isopropanol is 1:2, add the mixed solution with 200% tare weight, and recover the bath solution after rotating for 600min;
[0045] (4) Add acetone with a tare weight of 200%, take it out after rotating for 240 minutes, and obtain wet white skin.
Embodiment 3
[0047] (1) Adjust the pH of the pickled skin to about 5.4, and squeeze the water;
[0048] (2) Add the above-mentioned squeezed skin into the rotatable sealing device, add absolute ethanol with a tare weight of 400%, recover the bath liquid after rotating for 60 minutes, and then add ethanol for the second dehydration;
[0049] (3) Configure a mixed solution of acetone and absolute ethanol, the ratio of acetone and ethanol is 1:1, add the mixed solution with a tare weight of 400%, and recover the bath solution after rotating for 60 minutes;
[0050] (4) Add acetone with a tare weight of 400%, take it out after rotating for 60 minutes, and obtain wet white skin.
