氫氧化鉀的使用大多應用于化工行業(yè)和工業(yè)的生產(chǎn),很多人在使用這種物質的時候,會產(chǎn)生疑問,不同含量的這種物質,對使用會不會有影響呢,下面這篇文章為大家詳細講解,大家一起來了解一下吧。
The use of potassium hydroxide is mostly used in the chemical industry and industrial production. When using this substance, many people will ask whether different contents of this substance will have an impact on the use. The following article will give you a detailed explanation. Let's have a look.
性質與穩(wěn)定性
Nature and stability
易潮解。暴露于空氣中時,易吸收二氧化碳和水分,逐漸變成碳酸鉀。易溶于水,溶解時放出大量溶解熱,有很強的吸水性,在空氣中能吸收水分而溶解,并吸收二氧化碳逐漸變成碳酸鉀。溶于乙醇,微溶于醚。有很強的堿性和腐蝕性,其性質與燒堿相似。能引起灼傷。易于吸收空氣中的水分和CO2。
Easily deliquescence. When exposed to the air, it is easy to absorb carbon dioxide and water and gradually become potassium carbonate. It is easy to dissolve in water, emits a lot of heat of dissolution when dissolved, and has strong water absorption. It can absorb water and dissolve in the air, and absorb carbon dioxide and gradually become potassium carbonate. Soluble in ethanol, slightly soluble in ether. It has strong alkalinity and corrosivity, and its property is similar to that of caustic soda. Can cause burns. It is easy to absorb moisture and CO2 in the air.

這個是沒有什么區(qū)別的,之所以你用90%、95%氫氧化鉀中和的時候出現(xiàn)差別還是與脂肪酸中和度不同造成的,皂有個明顯的特點(鉀皂或者鈉皂)就是在水中溶解度都不怎么好,當你中和到一定程度后生成的脂肪酸鹽會析出來包裹一部分脂肪酸,使之無法繼續(xù)中和,這就造成了體系物理狀態(tài)不一樣。
There is no difference. The reason why you neutralize with 90% and 95% potassium hydroxide is that the difference is caused by the difference in the neutralization degree of fatty acids. The soap has an obvious characteristic (potassium soap or sodium soap) that the solubility in water is not very good. When you neutralize to a certain degree, the fatty acid salt generated will separate out and wrap some fatty acids, making it impossible to continue to neutralize, which results in different physical states of the system.
于用多大濃度的,那是工藝制作過程的問題;皂化不達標,我也可以理解為動力不足,中和均質不給力。粘稠的話,你少用一部分水,當然會稍粘稠些,你可以另外兌水啊,如果你想加水的話。你完全根據(jù)自己的需要去調節(jié)濃度、配方用量,起作用的還是脂肪酸鉀。另外這點影響和脂肪酸的碳鏈分布比起來差遠了。
As for how much concentration is used, it is a question of the technological process; If the saponification fails to meet the standard, I can also understand that the power is insufficient, and neutralization and homogenization are not awesome. If it is sticky, you should use less water. Of course, it will be slightly sticky. You can add water if you want. You can adjust the concentration and dosage of the formula completely according to your own needs. It is potassium fatty acid that works. In addition, this effect is far worse than the carbon chain distribution of fatty acids.
我們在試驗室里做皂基,用過32%或50的的堿,我們做的是C1618皂漿,噴粉用的,粘稠。好好設計配方,嚴格按配方來試驗,有時候也要根據(jù)設備條件來調整一下,效果會更好。沒有必要拘泥于本質上沒有區(qū)別的事。
We used 32% or 50% alkali to make soap base in the laboratory, and we made C1618 soap paste, which is used for powder spraying, and is sticky. Design the formula well, test it strictly according to the formula, and sometimes adjust it according to the equipment conditions. The effect will be better. There is no need to stick to things that are essentially indistinguishable.
通過文中講解的內(nèi)容,大家可以大體了解到這種氫氧化鉀的使用中,不同含量的物質對使用不會產(chǎn)生影響,希望文中講解的內(nèi)容對大家有幫助作用,在以后的操作使用中也不會有那么多疑慮了。關注我們網(wǎng)站
