For a long time, the low-temperature deoxygenated water used in Qilu Rubber Plant's styrene-butadiene rubber plant was obtained by heating the demineralized water at 20°C to 105°C and then reducing the temperature with circulating water, wasting a lot of steam and circulating water. In 2007, the plant made a technical transformation. The technicians directly deoxygenated the demineralized water at 20°C through a degassing membrane deoxygenation equipment to eliminate the consumption of steam and circulating water. Since the implementation of the transformation, the system has saved 28,000 tons of steam and reduced 4 million tons of recycled water.
Dichloromethane (DCM) is a multifunctional and powerful chloride solvent known for its high solubility. As a solvent, it is often used for coating removal, metal cleaning and polishing; It can also be used as a processing solvent in the production of drugs, polycarbonate, cellulose ester and photographic film, and as an extraction medium for aerosol propellant and food processing. Other uses include adhesives, cosmetics, plastic processing and foaming. Dichloromethane has many characteristics such as super solubility, low flammability, high cost efficiency, recyclability and rapid evaporation. Therefore, it has long been the preferred solvent for a variety of applications, mainly in polyurethane foam blowing, metal cleaner, adhesive, paint stripper and pharmaceuticals.
Dichloromethane is a widely used organic solvent, which is slightly soluble in water, easily soluble in ether and ethanol, and volatile at room temperature. It can cause poisoning if used carelessly. Many commonly used reagents contain dichloromethane, such as various paints, coatings, furniture polish and cleaner, hair styling agent, household air cleaner, deodorant, leather shoe polish and cleaner, etc.
