The caustic soda or lye or sodium hydroxide is a solid white color and alkaline substance and is a neutralizing agent. Caustic soda should be added directly to well water. By neutralizing acidic water, it prevents the pipes and pumps from being destroyed. This material has various uses including soap and detergent production, petrochemicals and water purification. Castic Soda or sodium hydroxide is divided into four categories, Liquid form or lye, prill form or pearls, Flake, and powder.
Motor supplements increase the efficiency of the engine and increase its life span and help repair metal surfaces of inner parts. There are many different car supplements, such as Fuel additives, Oil additives, High Mileage Oil Treatments and multipurpose additives. The use of motor oil supplements is essential for modern engines with internal combustion. Without engine oil supplements, there is the possibility of contamination of the engine oil, the breakdown of the chemical structure of the engine oil, the engine oil leaking out and the lack of engine protection at high temperatures. Oil supplements are thick and thicken engine oils. They also are formulated in terms of additives, in such a way, that they can optimize engine oil deficiencies and their effects.
Nowadays, considering the importance of a car engine health, the experts are working on creating a high quality engine oil. There are two important indicators in selecting a motor oil, SAE as viscosity index and API for motor oil quality level. At present, the engine oil is divided into three general types: Mineral (organic), Synthetic and Semi-synthetic, among which the synthetic oil has the highest quality. Typically, the engine oil should be replaced every 6,000 to 10,000 kilometers.
The population growth and human attention to health have caused the mass production of the cleansing agents. From the early nineteenth century, synthetic cleansers or detergents were introduced to the market. The chemical components of a cleaner are generally classified into three general categories: surfactants, Manufacturers (fillers) and Miscellaneous materials. Javel water, caustic soda, Calcium hypochlorite, Texapon, Sulfonic acid, formaldehyde, ferric chloride, Cocamide DEA, Cocamide propyl betaine, Hydrochloric acid, Chlorine and Vanadium oxide are widely used as cleansing agents and disinfectants.
