As an alkaline substance, potassium hydroxide has milder alkalinity than other products, and its effect in many fields is better than other alkalinity, so it will be used in the process of mold inspection.

在進行檢查的時候需要使用干凈的酒精棉球將皮膚破損的位置清理干凈，然后在使用玻璃片刮去在破損明顯的部位刮去一塊，建議在進行選擇的皮膚破損位置在丘疹根部或者是更里面的地方，還有就是破損的一些邊緣位置也是比較好進行試驗的。進行實驗的時候使用10％濃度的氫氧化鉀滴取1滴到承載片上面并且和上面的殘屑混合均勻。

Firstly, clean the damaged position of skin with clean alcohol cotton ball, and then scrape off a piece of obvious damaged part by using glass sheet. It is suggested that the skin damage position selected should be at the root of papule or more inside, and some edge positions of damaged skin should also be better for test. During the experiment, 1 drop of 10% potassium hydroxide was dropped onto the bearing plate and mixed with the debris.

之后再取出另一片玻璃片對其進行固定處理，然后使用10倍鏡和40倍鏡的顯微鏡進行觀察，在進行觀察的時候建議在低照明度的環境當中是倍鏡合適的。其在進行測試時候的優勢是除了可以溶解表皮蛋白之外，還可以在不破壞霉菌成分簽下使得霉菌不出現彌散的情況，并且將其保持在角質層細胞膜之間處于比較穩定的狀態。

After that, take out another piece of glass to fix it, and then use 10 times mirror and 40 times microscope to observe. When observing, it is suggested that double lens is appropriate in low light environment. In addition to dissolving epidermal protein, it can also make the mold not disperse without destroying the mold components, and keep it in a relatively stable state between the cuticle cell membrane.

上面介紹的就是使用氫氧化鉀進行霉菌檢查的工序，通過這里我們也是可以了解到在進行使用的時候除了在很多的工業當中可以使用到，但是其實在進行使用的時候很多的實驗室當中進行使用的量也都是非常多的。

The above is the use of potassium hydroxide for mold inspection process, through here we can also understand that in the use of in addition to many industries can be used, but in fact, in the use of a lot of laboratories in which the amount of use is very large.
