Embodiment 1

[0033] The biological degreasing agent in the present embodiment is made up of main agent, and its proportioning is as follows:

[0034] Phosphatidylglycerol 4.00%, alkyl glycoside 11.00%, alkyl ether carboxylate 7.00%, Bacillus subtilis, Bacillus polymyxa and Xanthophylla 6.00%, water 72.00%.

[0035] 1. According to this ratio, mix evenly in a test tank with a volume of 3 liters, and prepare 2 liters of main ingredients.

[0036] 2. Add 2 liters of 90# gasoline to another experimental tank with the same volume.

[0037] 3. The experimental oil used in this experiment is Purelube  SAE 30 Non-detergent Oil (manufactured by HAJ Inc.).

[0038] 4. In this experiment, whether 80% of the experimental oil on the Hastelloy sheet can be removed within 5 minutes is used as a sign to measure whether the degreaser has good oil removal ability: within 5 minutes, if the experimental oil removed from the Hastelloy sheet More than 80%, the degreaser is defined as having good degreasing ...

Embodiment 2

[0049] The biological degreasing agent in the present embodiment is made up of main agent, and its proportioning is as follows:

[0050] Phosphatidylglycerol 9.00%, alkyl glycoside 15.00%, alkyl ether carboxylate 20.00%, Bacillus licheniformis, Bacillus megaterium and Xanthobacter 4.00%, potassium chloride 0.3%, sodium sulfate 0.2%, water 51.50%.

[0051] 1. Based on the formulations in Example 1 and Example 2, respectively prepare 20 liters of main ingredients. Then store in a 20-liter airtight container in a cool, dry place.

[0052] 2. The experimental oil used in this experiment is Purelube  SAE 30 Non-detergent Oil (manufactured by HAJ Inc.).

[0053] 3. On the day when the main ingredient is prepared, dilute the main ingredient with water at a ratio of 1:20. Then use exactly the same degreasing ability test method in embodiment 1, test the degreasing ability of two formulas respectively, test continuously for 7 days.

[0054] 4. After storage for 2 weeks, 4 weeks an...

Embodiment 3

[0063] The biological degreasing agent in the present embodiment is made up of main agent, and its proportioning is as follows:

[0064] Main ingredients: rhamnolipid 10.00%, polyoxyethylene ether 15.00%, Bacillus subtilis 5.00%, sodium sulfate 0.10%, sodium chloride 0.40%, lipase 0.20%, water 69.30%; in the degreasing tank, mix well .

[0065] 1. Degreasing test: The following is a comparison of the degreasing speed of the biological degreasing agent formula for different oils stripped from the standard Hastelloy sheet under static and dynamic conditions.

[0066] 2. The specific experimental steps of the static test are as follows:

[0067] (1) Take 2 liters of the main agent, dilute it with water at a ratio of 1:30 in the experimental tank, and prepare 60 liters of working solution.

[0068] (2) Add 10 grams of auxiliary agent to the diluted main agent, and stir evenly to prepare a biological degreasing agent.

[0069] (3) Take 15 Hastelloy tablets of standard specificat...

Abstract

The invention discloses a biological degreaser for degreasing pretreatment in metal processing industry and method for processing greasy dirt on metal surfaces, which integrates the two independent processes of grease removing and greasy dirt decomposing, the biological degreaser containing oil-degraded microorganisms can not only scale off greasy dirt from metal surfaces, but also decompose the greasy dirt simultaneously.

Description

technical field [0001] The invention relates to the fields of metal surface treatment and waste water treatment, in particular to a biological degreasing agent with dual functions of degreasing and decomposing oil stains and a method for treating oil stains on metal surfaces. Background technique [0002] The processing industry, especially the metal processing industry, such as the electroplating industry, is a heavy polluting industry. In the surface treatment and processing of metal or plastic workpieces, many petroleum derivatives (mineral oil), animal fats and vegetable fats and other oil additives are used, such as anti-rust oil, cutting oil, stamping oil, coolant , lubricating oil, etc. These grease additives play an important role in protecting workpieces and equipment from rust or corrosion. But at the same time, when these workpieces and materials need to be made into final products, these grease additives must be removed from the surface of the workpiece, otherw...
