Kev ua xab npum yog txheej txheem ntxim nyiam uas tau xyaum ntau pua xyoo thoob ntiaj teb. Yog tias koj tshiab rau cov khoom siv tes ua, ib qho tseem ceeb tshaj plaws kom nkag siab yog lub luag haujlwm ntawm lye hauv kev ua xab npum. Lye yog ib qho tshuaj caustic uas tsim nyog rau saponification, uas yog tshuaj lom neeg cov tshuaj tiv thaiv uas hloov roj thiab rog rau hauv xab npum.
Muaj ob hom lye uas tuaj yeem siv los ua xab npum: sodium hydroxide (NaOH) thiab potassium hydroxide (KOH). Thaum NaOH siv los ua cov khoom siv xab npum, KOH yog siv los ua cov xab npum ua kua, xab npum cream, thiab lwm yam khoom siv tu tus kheej.
Potassium Hydroxide yog dab tsi?
Potassium hydroxide (KOH) yog cov khoom dawb, tsw ntxhiab uas tseem hu ua caustic potash. Nws yog ib yam khoom muaj zog alkaline uas yog soluble hauv dej, ua rau nws yooj yim heev rau kev ua haujlwm nrog xab npum ua.
KOH yog tsim los ntawm dissolving potassium carbonate hauv dej thiab tom qab ntawd ntxiv calcium hydroxide (tseem hu ua slaked txiv qaub). Tom qab ntawd cov sib tov yog lim thiab evaporated kom tau txais cov ntshiab potassium hydroxide crystals.
Vim li cas thiaj siv Potassium Hydroxide hauv xab npum?
KOH yog siv los ua xab npum vim nws muaj pH siab dua NaOH. Qhov no txhais tau hais tias nws muaj zog alkaline cov tshuaj tiv thaiv nrog cov roj thiab cov rog, uas tso cai rau nws los tsim cov kua ntau dua, creamy xab npum uas zoo meej rau cov khoom tu tus kheej.
Thaum KOH ua ke nrog cov roj thiab cov rog, nws hnov mob kom tawg cov tshuaj lom neeg hauv cov molecules. Qhov tshwm sim yog xab npum thiab glycerin, uas yog ob qho tib si tseem ceeb ntawm cov txheej txheem saponification. Thaum NaOH tuaj yeem tsim tau xab npum thiab glycerin, qhov kawg tshwm sim yog ib qho nyuaj, cov xab npum uas zoo dua rau cov xab npum bar.
Yuav Ua Li Cas Siv Potassium Hydroxide hauv Soap Ua
Yog tias koj tshiab rau xab npum, nws yog ib qho tseem ceeb kom nkag siab txog kev ceev faj txog kev nyab xeeb uas yuav tsum tau ua thaum ua haujlwm nrog lye. Nco ntsoov hnav hnab looj tes tiv thaiv, lub tsho ntev ntev, thiab tiv thaiv qhov muag thaum tuav KOH.
Thaum ua kua xab npum lossis lwm yam khoom siv tu tus kheej, tus nqi ntawm KOH xav tau yuav nyob ntawm daim ntawv qhia koj siv. Feem ntau, koj yuav xav tau txog 0.3 ooj ntawm KOH rau txhua ooj roj siv hauv daim ntawv qhia.
Txhawm rau siv KOH hauv kev ua xab npum, ua ntej yaj hauv dej. Thaum nws tau yaj lawm, ntxiv nws maj mam rau cov roj thiab cov rog uas koj siv, nplawm tas li. Tshav sib tov maj mam kom txog thaum nws ncav cuag qhov xav tau sib xws.

Ntim: 25 kg nruab nrab hnab, jumble hnab, los yog IBC nruas.
Qhov chaw cia:
Ib puag ncig qhuav: Khaws cia rau hauv qhov chaw txias, qhuav, zoo-ventilated los tiv thaiv kev nqus dej.
Nyob deb ntawm Acids: KOH yuav tsum khaws cia kom deb ntawm cov kua qaub, vim nws tuaj yeem cuam tshuam nrog cov tshuaj acidic.
Kub: Khaws rau ntawm chav tsev kub thiab tsis txhob muab tso rau hauv qhov cua sov, uas yuav ua rau muaj feem cuam tshuam.
