Methods of control include directly adjusting the pH, adding phosphates, silicates as an alternative corrosion inhibitor, or adding bicarbonates for buffer. [ 2 ] Orthophosphates may be added in tap water treatment systems to prevent leaching of lead and copper from water pipes and reduce the ion content in tap water to safer, legal levels. [ 2 ]
To prevent wax deposition, various techniques can be used, including heating the fluid to dissolve wax back into the oil phase, adding chemicals to prevent wax formation, and using specialized equipment or a pig to remove the wax deposit from the pipe wall surface. The term "wax deposition" should not be confused with the term "wax precipitation".
New applications are in inkjet systems where gas in the ink forms bubbles that degrade print quality, a degassing unit is placed prior to the print head to remove gas and prevent the buildup of bubbles keeping good jetting and print quality. The above three methods are used to remove all dissolved gases. Below are methods for more selective ...
Sulfites or sulphites are compounds that contain the sulfite ion (or the sulfate(IV) ion, from its correct systematic name), SO 2− 3. The sulfite ion is the conjugate base of bisulfite. Although its acid (sulfurous acid) is elusive, [1] its salts are widely used. Sulfites are substances that naturally occur in some foods and the human body.
The wax used within the thermostat is specially manufactured for the purpose. Unlike a standard paraffin wax, which has a relatively wide range of carbon chain lengths, a wax used in the thermostat application has a very narrow range of carbon molecule chains. The extent of the chains is usually determined by the melting characteristics ...
Even a small amount of grapes or raisins can cause kidney failure in dogs. And no, scientists still don’t know why they’re so toxic—but we do know it’s not worth the risk. 3. Onions and Garlic
