For example, all kinds of soaps we use in our daily life are made of alkaline substances, and we need to pay attention to avoid direct contact with alkaline substances. Today, let's take a detailed look at the process of making soap with potassium hydroxide.

1、我們首先是需要將堿性物質(zhì)倒入到水當中，然后將其攪拌成堿溶液沒有固體即可，在這個過程當中一定要注意避免將氫氧化鉀弄到皮膚上，因為堿性物質(zhì)對于我們?nèi)梭w的皮膚是有很強的腐蝕作用的。

1. We first need to pour alkaline substances into water, and then stir them into an alkaline solution. There is no solid. In this process, we must pay attention to avoid getting potassium hydroxide on the skin, because alkaline substances have a strong corrosive effect on our human skin.

2、等到堿溶液的溫度在降到了和室內(nèi)溫度差不多的時候，可以往當中添加進去廢油差不多再持續(xù)的攪拌3~5分鐘。

2. When the temperature of the alkali solution is about the same as the indoor temperature, the waste oil can be added and stirred for 3 ~ 5 minutes.

3、接下來需要倒入到模具中即可，在選擇模具的時候一定要選擇合適材料的，差不多3-5的時間即可凝固不過像是我們自己制作的，需要等到在凝結(jié)之后再風干半個月的時候才可以進行使用。

3. Next, you need to pour it into the mold. When selecting the mold, you must select the appropriate material. It can solidify in about 3-5 times. However, it is made by ourselves. It can be used only when it is air dried for half a month after solidification.

4、在制作的過程當中如果想要添加一些有顏色、香味等，也是可以根據(jù)相應的配方往當中添加色素或者是香精。

4, in the process of production, if you want to add some colors and fragrances, you can add pigment or essence according to the corresponding formula.

5、不過在添加一下物質(zhì)的時候一定要注意控制好各種的計量，尤其是往當中添加的堿性物質(zhì)劑量是一定要控制好的。

5. However, when adding substances, we must pay attention to controlling the measurement of various substances, especially the dose of alkaline substances added to them.
