一般人對堿的知識不足,故對于用堿來制皂這檔事常心存畏懼,進而忽略使用時之守則,其實堿雖是一種具有高度危險的材料,但只要稍微細心一些,必可保制皂時的平安。
Most people have insufficient knowledge of alkali, so they are often afraid of using alkali to make soap, and then ignore the safety rules when using it. In fact, although alkali is a highly dangerous material, as long as it is a little careful, it can ensure the safety when making soap.
舉例來說,先要知道堿很容易受潮,且容易與水結(jié)合成為「強堿」。一般來說干燥的固體狀態(tài)氫氧化鈉尚無很大的危險性,但它易與空氣中的水結(jié)合(受潮)成為無色無味的強堿,此時就是一種具有強烈腐蝕性的物質(zhì),是具危險性的(故DIY制皂時,工作桌上不要放置飲食,以免食物沾到強堿水而誤食)。
For example, we should first know that alkali is easily affected by moisture and easily combines with water to become a "strong alkali". Generally speaking, sodium hydroxide in dry solid state is not very dangerous, but it is easy to combine with water in the air (affected by moisture) to become a colorless and odorless strong alkali. At this time, it is a substance with strong corrosivity and is dangerous (so when DIY soap is made, don't put food on the work table, so as to avoid accidental eating of food stained with strong alkaline water).
因此,貯存
氫氧化鉀時須保證它不能與空氣接觸,建議用不容易破裂且可密封的罐子貯存。使用后也一定要迅速將它再度密封,免得固態(tài)的氫氧化鈉與空氣中的水氣結(jié)合成為傷人的強堿。含水或在液體中的氫氧化鈉,當(dāng)水分揮發(fā)后會剩下形成白色粉狀或塊狀的氫氧化鈉,也不可對之掉以輕心,因為這些白色粉狀或塊狀物還是屬于強堿性質(zhì),接觸到還是會受傷的。
Therefore, when storing potassium hydroxide, it must be ensured that it cannot be in contact with air. It is recommended to store it in a jar that is not easy to crack and can be sealed. After use, it must be sealed again quickly, so as to prevent the solid sodium hydroxide from combining with the water vapor in the air to become a harmful strong alkali. Sodium hydroxide containing water or in liquid will be left to form white powdery or blocky sodium hydroxide after the water volatilizes, and it should not be taken lightly, because these white powdery or blocky substances are still of strong alkaline nature, and they will be injured if they are exposed.
手工皂常用堿(氫氧化鈉)分兩種,一種是顆粒狀,簡稱粒堿或珠堿,特點是融化快,放熱劇烈,升溫迅速,容易飄散,容易靜電吸附;另一種是片堿,塊狀,融化較慢,放熱稍慢,升溫較慢。兩種都可以,可根據(jù)自己的需要選擇。
There are two kinds of alkali (sodium hydroxide) commonly used in hand soap. One is granular, which is abbreviated as granular alkali or pearl alkali. It is characterized by rapid melting, intense heat release, rapid temperature rise, easy dispersion and easy electrostatic adsorption; The other is flake alkali, massive, which melts slowly, releases heat slightly slowly, and heats up slowly. Both are OK, you can choose according to your own needs.
堿是多種元素的結(jié)合物,即不純也不穩(wěn)定,常常和其他元素或化合物產(chǎn)生化學(xué)反應(yīng)。所以大家如果不得不去使用的時候需要提前做好相關(guān)的準(zhǔn)備,更多事項就來網(wǎng)站

Alkali is a combination of many elements, which is neither pure nor stable, and often reacts with other elements or compounds. So if you have to use it, you need to make relevant preparations in advance, and come to the website for more matters http://www.tjxjw.com Consult.
