Problems solved by technology

Because these parts are heavily oily, and the spatial structure is complex and changeable, ordinary surfactants are difficult to clean, and will cause a large amount of surfactants to pollute the environment
At present, the main solvents for cleaning industrial oil stains are mineral solvents such as kerosene and gasoline to dissolve various oil and grease dirt. Although this method is easy to operate, does not require special equipment and will not damage parts, it is more dangerous and The irritating odor produced is harmful to the human body and wastes a lot of resources

Embodiment Construction

[0009] This embodiment takes waste transmission gears as an example. The gears are taken from the internal gears of waste automobile transmissions and have been covered with oil for a long time without rust. To remove oil from the gears, follow the steps below.

[0010] 1) Raw material preparation: Take 50 kg of Sapindus sapinsia fruit pulp after depitting, crush it to about 40 meshes, add 150 grams of endoglucanase, add 200 kg of water to ensure that the raw materials are completely submerged, and store at room temperature for 36 hours. Hour.

[0011] 2) Cleaning agent preparation: Add 27.5 kg of absolute ethanol to the raw material obtained in step 1, heat and reflux in an oil bath at 110°C for 2 hours, and heat and condense in an oil bath at 80°C for 0.5 hour to obtain about 20 kg of reddish-brown viscous liquid. Then add 0.5 kg of sodium petroleum sulfonate, mix thoroughly and store for later use.

[0012] 3) Material preparation: Take 20 kg of cleaning agent obtained in...

Abstract

The invention provides an environment-friendly cleaning agent for cleaning remanufactured parts. The environment-friendly cleaning agent is prepared by adopting a method comprising the steps of collecting pulp of fruits after kernels are removed, crushing into 30-50 meshes, adding endoglucanase which accounts for 0.3-0.5 percent by weight that of soapberry pulp, completely immersing the endoglucanase in water, and placing for 24-48 hours at room temperature; controlling water, adding absolute ethyl alcohol which accounts for 50-60 percent by weight that of the soapberry pulp, and then, carrying out heating reflux in an oil bath at the temperature of 100-120 DEG C for 2-2.5 hours; adding petroleum sodium sulfonate which accounts for 0.5-2 percent by weight that of the soapberry pulp after cooling, and fully mixing to obtain red brown viscous liquid. The environment-friendly cleaning agent can be used for cleaning the manufactured parts, and is mainly used in an immersion cleaning stage and a washing stage; cleaned residual liquid is nontoxic and innocuous, has no pungent smell, and is basically free from corrosion. The environment-friendly cleaning agent can not combust, and is safe to human bodies, equipment, environment, metals and plastics without corrosion.

Description

technical field [0001] The invention belongs to the technical field of mechanical cleaning, in particular to an environment-friendly cleaning agent for cleaning remanufactured parts. Background technique [0002] In the entire gearbox remanufacturing process, the cleaning of parts is the most important link, and it is also a relatively special process. Because these parts are heavily oily, and the spatial structure is complex and changeable, common surfactants are difficult to clean, and will cause a large amount of surfactants to pollute the environment. At present, the main solvents for cleaning industrial oil stains are mineral solvents such as kerosene and gasoline to dissolve various oil and grease dirt. Although this method is easy to operate, does not require special equipment and will not damage parts, it is more dangerous and The irritating odor produced is harmful to the human body and wastes a lot of resources. Contents of the invention [0003] The purpose of...
