Remove Stubborn Stains With Industrial Degreasers

Saturday, August 7th, 2010

There are ample industrial degreasers that are available for use on electric motors, machinery and other types of applications. Almost all the degreasers in stores are biodegradable and environmentally agreeable. A degreaser can be used on ever so many appliances equivalent to vehicle machinery, garage work, etc. They are remarkable enough to remove even the toughest grease marks.

Industrial degreasers are uniquely formulated to erase the toughest spots with smallest effect on the skin and the environment. It is made up of exclusive chemicals that offer higher performance over a endless spread of situations. Every degreaser undergoes severe testing to make sure they conform to with local codes. The composition of chemicals used is powerful enough to dissolve grease instantaneously.

Their uses are not limited to mills, garages and machinery. They can be also used to clean BBQ grills, vehicle parts, etc. Degreasers produced nowadays are much safer than the older and highly combustible degreasers. They contain no petroleum solvents or acids that are disapproved by the USDA. In order to be compliant, all industrial degreasers have their own set of safety instructions and prevention methods in case there is eye contact. Heavy duty degreasers contain a strong chemical combination which could prove fatal if inhaled, come in contact with the eye or ingested.

Industrial degreasers can cut through grease and can be easily washed away. Work is made quick-and-simple by using these products. Industrial degreasers have the power of an extreme effect on stains while maintaining a mild effect on the skin and ecosystem. This product has no side effects and completely eco-friendly. Volatile Organic Compound are absent from this product which means they are non-toxic.

iTreecycle supplies industrial degreasers and plants one tree for every product it sells. The trees are planted in the name of the buyer and guaranteed by the United Nations Environment Programme: Plant for the Planet Billion Tree Campaign. We plant 1 tree for each product sold, with the exception of recycling where we plant 1 tree for each full box of empty cartridges sent to us. And for office supplies where we plant 1 tree for each 40 GBP spent.

Chemical Test Carbohydrate : The Proper Method to Examine Carbohydrate

Saturday, February 6th, 2010

A chemical test is a quantitative or qualitative process that is intended to prove the existence or to evaluate a chemical compound and or chemical group with the help of a reactant. To chemical test carbohydrate, there are a number of tests that can be conducted to determine if a sample contains carbohydrates and if it does, there are further tests that can be carried out to classify and identify it. The Molisch Test, The Iodine/Potassium Iodide Test, Benedict’s Test, Barfoed’s Test, Seliwanoff’s Test and Bial’s Test are chemical test carbohydrate.

Named after Austrian botanist Hans Molisch, the Molisch’s Test is a sensitive chemical test carbohydrate. Sulfuric acid desiccates the carbohydrate which results in the formation of an aldehyde which is compressed with two molecules of phenol that results in a purple or red colored compound. Next, the Molisch’s reagent,naphthol dissolved in ethanol, is mixed with the sample in a test tube. A small amount of concentrated sulfuric acid is gradually poured to the mixture along the wall of the test tube without mixing to generate a bottom layer. If a purple ring appears at the cross point between the acid and the test layers, a positive reaction is indicated.

Carbohydrates and monosaccharides will show a rapid positive test result in chemical test carbohydrate although disaccharides and polysaccharides has a much slower reaction. The Barfoed’s Test is a chemical test carbohydrate that detects the presence of monosaccharides. Placing one ml of a sample solution in a test tube, 3 ml of Barfoed’s reagent, a solution of acetic acid and acetate cupric solution are added. Heat the solution in a boiling water bath for three minutes and if a formation of a reddish precipitate appears, it tests positive for monosaccharides.

Named after the American chemist Stanley Rossiter Benedict,the Benedict’s test is a chemical test carbohydrate used as a test for the presence of reducing sugars. One ml of the sample solution should be placed in a test tube with a 2 ml solution of the Benedict’s reagent which contains sodium citrate and sodium carbonate mixed with a copper sulfate solution. A reddish precipitate should appear within the three minutes if any reducing sugars are present when the solution is heated in a boiling water bath for three minutes. Primarily, researchers conduct chemical test carbohydrates to examine the different reactions of carbohydrates with the reagents to categorize and detect its compounds.

Urban Survival: A Growing Trend in America

DISCLAIMER: This is a small clip of a Fox news report about urban survival (IOW the clip is not mine). Under the Fair Use Act I can post this clip and ppl can review and provide commentary and thoughts on the subject.

Generating Biodiesel By Means Of Sodium Hydroxide

Sunday, October 18th, 2009

There is a fuel that comes from vegetable oil or cooking oil.  You will just have to mix oil with other substances, like sodium hydroxide, which are fairly common.  The new chemical fuel has applications as a diesel engine.  In other occasions, it can be mixed with other petroleum-based fuels.  The result is no less than a fuel that is economical, safe and renewable. 

The truth is that you can definitely produce biodiesel from unused or even used oil.  You need the following items: 1000mL of vegetable oil, 3.5g of caustic soda or sodium hydroxide, and 200mL of methanol.  You likewise need to have the following materials: a blender (preferably with a low speed action), a digital weighing scale, glass containers (one for vegetable oil, another for methanol, and a wide-mouthed mixing plastic container), protective gloves, eye shield (protective glasses or goggles), and apron.  Take note that one of the chemicals, caustic soda is very dangerous to use so make use of safety measures always.  Likewise employ cautiousness when handling methanol. 

Make sure that the optimum temperature is seventy degrees Fahrenheit or higher when making biodiesel because the speed of chemical response relies on the temperature.  Thus, in a low ambient temperature, expect a slow response process. 

The process starts with pouring of the methanol into the blender that is positioned at the minimal speed.  Gradually put in the caustic soda until it totally melts in the solution.  This procedure creates a compound known as sodium methoxide.  When caustic soda has totally dissolved, add the one-liter vegetable oil.  The slow blending action must continue until about thirty minutes during which time the mixture must be uniform.  Empty the mixture into a wide-mouthed glass container.  Notice that the solution starts to divide into several sheets of fluids.  The layer at the base is glycerine.  On top of that is biodiesel.  Set this aside for a few more hours until the sheets divide fully.  This time you can simply empty biodiesel.  You can likewise use a pump to suction the top liquid out of the mixture.

Note that glycerine is not a waste product but a different valuable product of the process.  It has practical application in other industries.

Take note too that any unchanged engine operating on diesel may use unadulterated biodiesel or a blend of biodiesel and petroleum diesel.  It may be essential to use the solution when driving in cold climate particularly if air temperatures go down below 55 ºF.  Remember that unadulterated biodiesel can develop into viscous and thick when subjected to low temperatures.  Thus, you should choose to increase the proportions of petroleum diesel as the temperatures get down.

In accumulating the chemicals for your biodiesel making, make sure to keep them away from food products and specifically make sure to pile them properly away from beverages.  Again, one of the most dangerous ingredients is sodium hydroxide so take the required safety measures in handling and storage.
