Cleaning agents or hard-surface cleaners are substances (usually liquids, powders, sprays, or granules) used to remove dirt, including dust, stains, foul odors, and clutter on surfaces. [1] Purposes of cleaning agents include health , beauty, removing offensive odors, and avoiding the spread of dirt and contaminants to oneself and others.
Alkaline water electrolysis is a type of electrolysis that is characterized by having two electrodes operating in a liquid alkaline electrolyte. Commonly, a solution of potassium hydroxide (KOH) or sodium hydroxide (NaOH) at 25-40 wt% is used. [ 6 ]
Pellets of soda lye (sodium hydroxide) Pellets of potash lye (potassium hydroxide)Lye is a hydroxide, either sodium hydroxide or potassium hydroxide.The word lye most accurately refers to sodium hydroxide (NaOH), [citation needed] but historically has been conflated to include other alkali materials, most notably potassium hydroxide (KOH).
Considering the industrial production of hydrogen, and using current best processes for water electrolysis (PEM or alkaline electrolysis) which have an effective electrical efficiency of 70–80%, [68] [73] [74] producing 1 kg of hydrogen (which has a specific energy of 143 MJ/kg) requires 50–55 kW⋅h (180–200 MJ) of electricity.
Due to the vigorous reaction between the acid and water, such acidic drain openers should be added slowly into the pipe to be cleaned. Acidic drain openers (in very high concentrations) hydrolyze proteins and fats via acid hydrolysis (acid-catalyzed hydrolysis), similar to their alkaline versions: RCONH 2 (amide or proteins) + H 3 O + → NH 4 ...
Plastic rings will (hopefully) soon be eliminated. This hack might soon be an unnecessary relic of the past. Fortunately, many brands are making efforts to reduce or eliminate single-use items ...
The reduction of blowdown by dealkalization keeps the water treatment chemicals in the boiler longer, thus minimizing the amount of chemicals required for efficient, noncorrosive operation. [2] Carbonate and bicarbonate alkalinities are decomposed by heat in boiler water releasing carbon dioxide into the steam.
