Embodiment 1
[0031] Taking 5 g of livestock and poultry hair raw materials for the preparation of livestock and poultry hair keratin liquid as an example, other raw materials used and their preparation methods are as follows:
[0032] 1. Preparation of keratin stock solution by reduction hydrolysis
[0033] Reductive hydrolysis method: Weigh 5g of washed and dried livestock and poultry hair and put it in a flask, add 90g of water and 4g of sodium sulfite to mix, stir for 0.5 to 2 hours, filter out the livestock and poultry hair, wash it with deionized water, add 75g of water and 3g of hydrogen Sodium oxide, heated to 90°C with stirring for 3.5 hours to prepare keratin stock solution.
[0034] 2. Ultrasonic treatment
[0035] The keratin stock solution prepared in step 1 was irradiated with ultrasonic waves with a power of 600W for 3 minutes to prepare a livestock and poultry hair keratin solution.
[0036] 3. Dry
[0037] The livestock and poultry hair keratin liquid is put into a vacuu...
Embodiment 2
[0039] Taking 5 g of livestock and poultry hair raw materials for the preparation of livestock and poultry hair keratin liquid as an example, other raw materials used and their preparation methods are as follows:
[0040] In the process step 1 of preparing keratin stock solution by reduction hydrolysis method in Example 1, weigh 5 g of washed and dried livestock and poultry hair and place it in a flask, add 50 g of water and 0.05 g of sodium sulfite to mix, stir for 0.5 to 2 hours, and filter out the livestock and poultry hair , and washed with deionized water, added 50 g of water and 0.5 g of sodium hydroxide, heated to 70° C. for 4.5 hours with stirring, and prepared a keratin stock solution. In step 2 of the ultrasonic treatment process, the keratin stock solution prepared in step 1 is irradiated with ultrasonic power of 400W for 6 minutes to prepare a livestock and poultry hair keratin solution. In step 3 of the drying process, the livestock and poultry hair keratin liquid...
Embodiment 3
[0042] Taking 5 g of livestock and poultry hair raw materials for the preparation of livestock and poultry hair keratin liquid as an example, other raw materials used and their preparation methods are as follows:
[0043]In the process step 1 of preparing keratin stock solution by reducing hydrolysis method in Example 1, weigh 5 g of washed and dried livestock and poultry hair and place it in a flask, add 100 g of water and 7.5 g of sodium sulfite to mix, stir for 0.5 to 2 hours, and filter out the livestock and poultry hair , and washed with deionized water, added 100 g of water and 5 g of sodium hydroxide, heated to 100° C. for 2 hours with stirring, and prepared a keratin stock solution. In step 2 of the ultrasonic treatment process, the keratin stock solution prepared in step 1 is irradiated with ultrasonic power of 400W for 5 minutes to prepare a livestock and poultry hair keratin solution. In the drying process step 3, the livestock and poultry hair keratin liquid is put...
