While parts washer detergents based on sodium hydroxide are among the most aggressive parts washer cleaning chemicals, they are also considered environmental improvements over the solvent-based cleaning methods.We are open throughout the holiday season but our warehouse will be closed on: December 24th, weekends and public holidays. A parts washer heats detergent and water in a closed cabinet, spraying them at pressure against dirty parts for degreasing applications. This includes defoamers, surfactants, and rust inhibitors. Furthermore, pretzels and German lye rolls are glazed with a sodium hydroxide solution before baking to achieve crispiness.Īnother broad usage of sodium hydroxide is in the production of parts washer detergents. Olives can be soaked in sodium hydroxide for softening.
In the biodiesel industry, anhydrous sodium hydroxide is a catalyst for the transesterification of methanol and triglycerides.įood uses include washing or chemical peeling of fruits and vegetables, as well as chocolate, cocoa and soft drink processing, caramel coloring, poultry scalding, and thickening ice cream. This reaction converts a polished surface to a satin-like finish. Sodium hydroxide reacts with aluminum and water to produce hydrogen gas and sodium aluminate. All of these stages require a strongly alkaline environment with a pH > 10.5 at the end of the phase.
It plays a crucial role in several later stages of bleaching the brown pulp emerging from the pulping process. Sodium hydroxide is broadly applied in the pulping of wood for creating paper or regenerated fibers. Treating with sodium hydroxide eliminates sulfurous impurities through reaction with weak acids. The process known as caustic washing utilizes caustic soda to clean and improve low quality crude oil.
Additionally, caustic soda neutralizes any acid gas encountered in the geological formation as drilling progresses. It increases the mud viscosity and alkalinity in bentonite mud systems. In the petroleum industry, sodium hydroxide is utilized as an additive in drilling mud. Other applications include the manufacturing of sodium salts and detergents, pH regulation, and organic synthesis. Around half of the sodium hydroxide production is used by manufacturers, prevalently in the paper industry.
