Soaking time>24hr. Can the time be shortened?

The speed can be greatly increased by heating the chemical to 40~120°C. But heating requires temperature control equipment and air extraction equipment. And heating requires personnel to operate and manage. And the loss of medicament is relatively large.
Certain EPOXY resins must be removed by heating. But in this case, if it can be removed by soaking at room temperature, it is recommended not to heat it. By enlarging the soaking tank and multiplying the soaking quantity, the efficiency can be accelerated.
And if you throw the workpiece into it, don't bother him. After cleaning the buzzer a little the next day, throw it into another pot of potion to soak, and don't pay attention to him. There is no need to configure fixed personnel for the first two days.

How to clean the aluminum alloy parts so that no chemicals remain on the surface?

Do you want to wash it now? Or is it okay to wash it off?

If you use 3 tanks of medicine to soak, only the medicine remains, and it doesn't matter to wash it after drying. If you use less than 2 tanks of medicine to soak, there will be resin monomer dissolved in the medicine, and the resin will precipitate and solidify on the surface after drying. Can't wash off with water. (Please refer to the reply to 1.)

Can used medicine be reused? Can. How long does it take for the medicine to expire? The expiration time varies depending on the amount of resin you dissolve. How to judge the availability of drugs? The potion is unusable when it no longer has the ability to break down the resin. (Please refer to the reply to 1.) It is recommended to soak in 3 tanks of medicine. When the 1st tank fails, replace the 1st tank with the 2nd tank of medicine, replace the 2nd tank with the 3rd tank medicine, and fill the 3rd tank with new medicine.

What should I do with the used medicine if I want to throw it away?

Although the medicament is biodegradable, since the waste solvent contains resin, please collect a certain amount and hand it over to a solvent recycler for burning as a gas-electric co-generation fuel.

The kitchen gloves in the photo below, are they okay to use?
