Embodiment 1
[0045] Weigh each raw material according to the following mass fractions: 1% Surfactin, 2% rhamnolipid, 3% polyaspartic acid, 3% lysine, 3% sodium oxalate, 0.2% defoamer, and the balance is deionized water . The rhamnolipid is a mixture obtained from the fermentation of Pseudomonas, containing 50% wt of monosaccharide ring rhamnolipid, 20% wt of disaccharide ring rhamnolipid, and the molecular weight of polyaspartic acid is 1000.
[0046] According to the mass content of each substance, put deionized water, lysine and surfactant peptide Surfactin into the reaction kettle, mix and dissolve at 50°C for 3 hours, then add rhamnolipid, sodium polyaspartate and Sodium oxalate is placed in the reaction kettle, stirred at 50°C for 3 hours, so that the raw materials in the reaction kettle are mixed evenly, and finally the defoamer is added to obtain an environmentally friendly cleaning agent.
Embodiment 2
[0048] Weigh each raw material according to the following mass fraction: Surfactin 2%, rhamnolipid 4%, polyaspartic acid 1%, lysine 5%, sodium oxalate 5%, defoamer 0.5%, and the balance is deionized water . The rhamnolipid is a mixture obtained by fermentation of Burkholderia, containing 60% wt of monosaccharide ring rhamnolipid, 25% wt of disaccharide ring rhamnolipid, and the molecular weight of polyaspartic acid is 2000.
[0049] According to the mass content of each substance, put deionized water, lysine and surfactant peptide Surfactin into the reaction kettle, mix and dissolve at 55°C for 4 hours, then add rhamnolipid, sodium polyaspartate and Sodium oxalate is placed in the reaction kettle, stirred at 55°C for 2 hours, so that the raw materials in the reaction kettle are evenly mixed, and an environmentally friendly cleaning agent is obtained.
Embodiment 3
[0051] The raw materials were weighed according to the following mass fractions: 1% Surfactin, 5% rhamnolipid, 2% polyaspartic acid, 3% lysine, 4% sodium oxalate, 0.1% defoamer, and the balance was deionized water . The rhamnolipid is a mixture obtained by fermentation of Pseudomonas, containing 55% wt of monosaccharide ring rhamnolipid, 30% wt of disaccharide ring rhamnolipid, and the molecular weight of polyaspartic acid is 4000.
[0052] According to the mass content of each substance, put deionized water, lysine and surfactant peptide Surfactin into the reaction kettle, mix and dissolve at 60°C for 2 hours, then add rhamnolipid, sodium polyaspartate and Sodium oxalate is placed in the reaction kettle, stirred at 60°C for 2 hours, so that the raw materials in the reaction kettle are evenly mixed, and an environmentally friendly cleaning agent is obtained.
