For example, a variety 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 when making them. Today, let's take a detailed look at the process of making soap by potassium hydroxide manufacturers.

1、我们先是需要将碱性物质倒入到水当中，然后将其搅拌成碱溶液没有固体，在这个过程当中要注意禁止将氢氧化钾弄到皮肤上，因为碱性物质对于我们人体的皮肤是有很强的腐蚀作用的。

1. First, we need to pour alkaline substances into water, and then stir it into alkaline solution without solid. In this process, we should pay attention not to bring potassium hydroxide to the skin, because alkaline substances have a strong corrosive effect on our human skin.

2、等到碱溶液的温度在降到了和室内温度差不多的时候，可以往当中添加进去废油差不多再持续的搅拌3~5分钟。

2. When the temperature of the alkali solution is almost the same as that in the room, waste oil can be added into it, and the stirring can be continued for about 3 ~ 5 minutes.

3、接下来需要倒入到模具中，在选择模具的时候要选择适合的材料，差不多3-5的时间凝固不过像是我们自己制作的，需要等到在凝结之后再风干半个月的时候才可以进行使用。

3. Next, we need to pour it into the mold. When choosing the mold, we need to choose the appropriate material. It takes about 3-5 minutes to solidify, but it's like we made it ourselves. We need to wait until it's condensed and then dried for half a month before we can use it.

4、在制作的过程当中如果想要添加一些有颜色、香味等，也是可以根据相应的配方往当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、不过在添加一下物质的时候要注意控制好对种的计量，还有是往当中添加的碱性物质剂量是要控制好的。

5. However, when adding substances, we should pay attention to control the metering of species, and the dosage of alkaline substances added to them should be controlled.
