Problems solved by technology

However, the existing wax mold cleaners on the market generally use solvents such as ketones and aromatic hydrocarbons, which are highly volatile, harmful to the body, and pollute the environment. The volatility of the solution on the surface of the wax mold is too poor , easy to accumulate fluid, and after use, it is necessary to use clean water to clean the surface of the wax model again, causing secondary pollution, generating a large amount of waste water, affecting the environment, and increasing the cost of sewage treatment for enterprises

Embodiment 1

[0014] A cleaning agent for oil stains on the surface of artificial joint wax models: at 22°C and without open flames around, wear anti-dissolving gloves, pour 50kg of limonene solution with a mass concentration of 85% and 75kg of limonene solution with a mass concentration of 95% 2-phenylthioethanol; stirred at a constant speed of 35 rad / min for 5 minutes, covered with a stainless steel lid of a stainless steel tank, and left for more than 4 hours to obtain a cleaning agent. According to the test statistics, after cleaning 8600 strings of wax pieces in this volume of cleaning solution or using it for 2 months, the cleaning effect begins to decline, and the solution needs to be replaced.

[0015] A treatment method for oil stains on the surface of artificial joint wax models: immerse the wax models in the above-mentioned cleaning agent; pay attention when cleaning the wax models, because limonene itself has a strong decomposition ability, so it is stipulated that the cleaning t...

Abstract

The invention discloses a cleaning agent and a treatment method for oil stains on the surface of artificial joint wax models, belonging to the technical field of wax model cleaning. The cleaning agent is formed by mixing a limonene solution with a mass concentration of 85%-95% and 2-phenylthioethanol with a mass concentration of more than 95%, and the volume ratio of the limonene solution to 2-phenylthioethanol is 2-2.2 : 2.8‑3. After using the cleaning agent and treatment method provided by the present invention to clean the artificial joint wax mold, the surface of the wax piece has no oil stains, no corrosion marks, no need to use clean water to rinse, does not contain harmful substances, and will not cause harm to the human body, and the waste liquid after cleaning It can also be recycled and reused to clean the handwriting left by the oil-based pen after writing.

Description

technical field [0001] The invention relates to a cleaning agent and a treatment method for oil stains on the surface of artificial joint wax models, belonging to the technical field of wax model cleaning. Background technique [0002] In the field of investment casting artificial joints, in order to facilitate the removal of the wax mold after wax pressing, some oily release agent will be sprayed in the mold cavity in advance, so the surface of the pressed artificial joint wax mold must have oily release agent If the wax molds attached with oil-based release agent are not cleaned cleanly, the cleaning agent will penetrate into the wax pieces during the cleaning process and corrode the surface of the wax pieces, which will directly affect the coating effect of the slurry on the wax pieces and after pouring. The surface state of products, especially artificial joints, artificial joint castings have extremely high requirements on surface quality, which needs to reach the stand...
