Some 270,000–360,000 tonnes (600–800 million pounds) of castor oil are produced annually for a variety of uses. [4] Castor oil and its derivatives are used in the manufacturing of soaps , lubricants , hydraulic and brake fluids , paints , dyes , coatings , inks , cold-resistant plastics , waxes and polishes, nylon , and perfumes .
Polishing is the process of creating a smooth and shiny surface by rubbing it or by applying a chemical treatment, leaving a clean surface with a significant specular reflection (still limited by the index of refraction of the material according to the Fresnel equations). [1]
Ricin (/ ˈ r aɪ s ɪ n / RY-sin) is a lectin (a carbohydrate-binding protein) and a highly potent toxin produced in the seeds of the castor oil plant, Ricinus communis.The median lethal dose (LD 50) of ricin for mice is around 22 micrograms per kilogram of body weight via intraperitoneal injection.
While the type and amount of surfactant determine what properties will be affected, other chemicals in a paint can alter the overall effect the surfactants may have on the paint. [6] Elasticity has been found to either increase or decrease in latex paints depending on the amount of TiO 2 present.
The environmental impact of paint can vary depending on the type of paint used and mitigation measures. Traditional painting materials and processes can have harmful effects on the environment, including those from the use of lead and other additives. Measures can be taken to reduce its environmental effects, including accurately estimating ...
As electropolishing can also be used to sterilize workpieces, the process plays an essential role in the food, medical, and pharmaceutical industries. [ 5 ] It is commonly used in the post-production of large metal pieces such as those used in drums of washing machines, bodies of ocean vessels and aircraft, and automobiles.
Brasso has also been used to polish out scratches in plastics: It has been used to polish CDs, DVDs, screens, and pools to repair scratches. It is a mild solvent and an extremely fine abrasive, so when applied to the reflective surface of the disc and rubbed radially (in straight lines between the edge and centre), it can smooth scratches and reduce their effect.
Serving sizes on nutrition labelling on food packages in Canada employ the metric cup of 250 mL, with nutrition labelling in the US using a cup of 240 mL, based on the US customary cup. [ 4 ] * In the UK, teaspoons and tablespoons are formally 1 / 160 and 1 / 40 of an imperial pint (3·55 mL and 14·21 mL), respectively.
