Potassium Hydroxide Flake
Formula: KOJ
Molar MassYog ': 56,11 g/mol
Qhov tshwm sim: Dawb tawv
Solubility: Siab soluble hauv dej, ua kom sov ntau thaum yaj
pH: Tsim cov tshuaj alkaline heev (pab) thaum tov nrog dej
Ua xab npum: Nws reacts nrog cov rog los tsim cov poov tshuaj ntsev, siv rau hauv cov mos mos thiab kua xab npum.
Tshuaj Synthesis: Nws yog ib qho precursor rau ntau lwm cov tshuaj potassium.
Roj teeb: KOH yog siv los ua electrolyte hauv alkaline roj teeb.
Ntxuav: Vim nws muaj peev xwm zom cov roj thiab cov rog, nws yog siv rau hauv kev lag luam tu khoom.
pH tswj: Nws yog siv los kho cov pH hauv kev kho dej, kev ua liaj ua teb, thiab lwm yam txheej txheem.
Kev txiav txim siab txog kev nyab xeeb:
Potassium hydroxide yog corrosive thiab tuaj yeem ua rau mob hnyav heev. Thaum tuav nws, cov cuab yeej tiv thaiv xws li hnab looj tes thiab qhov muag tiv thaiv yuav tsum hnav. Nws kuj tuaj yeem ua rau khaus khaus rau ntawm lub ntsws yog tias nqus tau.

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.
