This bottle, which you buy at the grocery store to get clean white clothes, has its own name - and it is not chlorine bleach. This is a common misconception - the correct name for the ingredient is sodium hypochlorite. Bleach is a term for a class of chemicals called oxidants. Oxidizers are highly reactive chemicals that cause the destruction of many organic compounds, such as dyes, pigments and food stains, which leads to bleaching or "bleaching." This high degree of reactivity is useful in certain applications, but can also cause problems.
Most household bleach consists of only 6% sodium hypochlorite. The rest of the gallon-sized bottle is 94% simple H2O. However, the type of bleach used for medium pressure washer is a higher industrial grade of 10-12% sodium hypochlorite. There are more than 50 kinds of products from around the world called bleaching or bleaching agents - a free term, because a word in its simple definition simply means that it will remove color. Dyes and pigments have alternating double molecular bonds that create color. The oxidative reaction of bleach destroys these molecules with a double bond, which makes their chromosomes shorter and therefore absorbs light at shorter wavelengths. This process does what had color, now looks white. Some bleach or bleaching agents simply make the double bond the only one that does not allow light to be absorbed.
A popular type of bleach in recent years is less reactive and slower working oxygen or peroxide bleach, such as sodium percarbonate, persulfate or sodium perborate. These works release oxygen, but this time, hydrogen peroxide is the active ingredient. Hydrogen peroxide bleaches have a lower whitening effect and are slower. This allows it to be used on many colored surfaces and colored fabrics.
Bleach, the influence of the bubble and the connection with France
Bleach is an alkaline solution created by bubbly chlorine gas with electrolysis through a solution of sodium hydroxide, usually called alkali, to regulate its pH to 12-13%. This setting improves its stability. Liquid hypochlorite bleach was first discovered in 1787 in France near Paris by chemist Claude Louis Berthollet. Bleach is known as Eau de Javel in France, after the village where it was first produced. It was originally used for bleaching textiles and was not until Louis Pasteur and his work with him at the end of the nineteenth century became widely used as a disinfectant and disinfectant. This is the biggest reason that bleach is used in combination with pressure washing today - it is a great disinfectant properties and the ability to kill and bleach stains from mold, fungi and mold. Bleach kills microbial forms by reacting (oxidizing) and destroying their cell membranes and cellular proteins. For normal surface disinfection, solutions of 50-100 ppm (parts per million) of bleach in water can be used. Higher levels of 1–3% chlorine are needed to remove mold stains. For swimming pools 1-3 ppm Chlorine must be maintained. Chlorinated isocyanurates and calcium hypochlorite are powders that are more resistant than liquid bleach, and for this reason are often used in pools. When dissolved in water, they form hypochlorite and act just like liquid bleach. Bleach can remove color in quantities like 1-3 ppm with water. Did you know? Liquid bleach will slowly lose its chlorine content with age, with its effect on the air and even faster in high temperature conditions or when exposed to sunlight. This is why chlorine levels in the pool are constantly monitored and why whitening bottles are never cleaned. Liquid bleach should be tightly closed and stored in a cool, dry and well-ventilated area. For example, in a hot summer, a 12% bleaching solution can lose 1% per week, up to 10% in two weeks and be up to 8% per month, but in a cold winter, which can be cut in half. This is what the manufacturers of chloroxox bleach are talking about. “Bleach solutions must be made fresh daily. After dilution, the bleach quickly breaks - primarily in salt and water. ” ** And that "Clorox® Regular-Bleach should be replaced every year and stored in accordance with the instructions for optimal performance." * * For washing under pressure, it would be best to buy something that you can use for several months, and only if necessary remove bleach cleaning solutions, and not store large quantities in transparent or half-open containers in the hot state of the sun.
Mold? Bleach alone is not enough.
For years, bleach has been used only with single-use disposable single-axis detergents for cleaning the surface, such as a house or concrete, which has molds and mildew wipes. But bleach alone with water will be beaded and spotty application results can occur. Adding a compatible detergent will allow the solution to "wash" the surface, giving even results. Be especially careful to ensure that the detergent is suitable and labeled for use in chlorine solutions. If you are unsure, contact the detergent manufacturer. Using an incompetent detergent can be dangerous! Another TSP (Tri-Sodium Phosphate) additive is recommended by some companies and industries, such as the association for the production of asphalt coatings exclusively today. In fact, they recognize their bleach recipe as the only way to remove the black stripes that form on their tiles. Black discoloration, which is found to stain an asphalt pavement, is actually an algae or mold called Glocapsa Magma. Asphalt race itself is a source of food for algae. They recommend a bleach recipe that safely removes algae, but only on the surface. Using 12% bleach, solutions range from one TSP cup, from one gallon bleach and five gallons of water to one TSP cup, and 2.5 gallons each of bleach and water. material surfaces will simply grow when conditions return, including shade and moisture or water, whitening which is 90% or more. Therefore, even with the act of cleaning mold and mildew with bleach and water, which can give new fuel to the fire for the new mold growth cycle. Please note that TSP is prohibited in laundry products in some parts of the country, mainly near the oceans, such as in the Chesapeake areas, MD and San Francisco, California. You may need to check with your local clean water authority before using products that are mixed with TSPs that can be put into the water system. There is no real way to dispose of an unused full strength bleach, except to first neutralize chlorine and then lower the pH before removing. To do this correctly, you must transfer it to the RCRA generator or cleaner.
Vegetation and Pollution -Business
Bleach has several problems when used in pressure washing. The smallest of these is that if it is not enough to wash and dilute with large volumes of water, the drain can kill vegetation, plants and grass surrounding a house, pavement or driveways. Bleach should also be properly stored and, as a rule, should never be mixed with anything other than water or certain labels compatible with chlorine detergents. Never mix bleach with ammonia and ammonia cleaning solutions. Mixing bleach with ammonia or nitrogen compounds will result in extremely irritating and explosive compounds called chloramines. When mixed with acids, a less stable solution of chlorine, called hypochlorous acid, is formed, which then releases toxic chlorine gas into the air. Commercial bleach contains additional alkalis in its formulas to maintain the solution at a very high pH of about 12 to prevent chlorine from becoming gaseous, but acids can easily neutralize this excess. Mixing bleach with incompatible chemicals can lead to anything from minor irritations to skin, eyes, nose and throat to extremely dangerous situations of deadly vapors that burn lung tissue, leading to respiratory arrest or death or the generation of explosive gases. You should never reuse containers that previously contained bleach for mixing or storing any other chemical or cleaning agent for this very reason, if they were not well rinsed. When working with water bleach, protection of workers should be goggles, imperfect gloves, an apron and waterproof boots on a long shirt with long sleeves and long trousers. You also need to regularly check the equipment on which you run the bleach to make sure that the metal parts have not been compromised. Clorox® state manufacturers “Many spray bottles contain metal parts in a trigger sprayer. Bleach will corrode these parts over time. ” ** Always rinse all metal metering parts well with clean water and do not leave bleach solutions in them when not in use.
If properly treated and treated with respect, bleach is a friend to the pressure washing industry because of its disinfectant action, its ability to kill mold and bleach.
