Semi water-based cleaning agent and a half water-based cleaning agent, also known as quasi-water-based cleaning agent, is such as alcohols, organic hydrocarbons from high-boiling solvents and active agent components. Usually containing 5% to 20% moisture metal cleaning agent, generally difficult to burn, but the warm wash water content properly controlled, may produce combustion phenomenon. Semi-water-based cleaning solvent wash a little different, it is the principle of separating and removing the car wash cleaners, instead of being dissolved. In order to prevent peeling of the oil has been re-attached to the object to be cleaned, the cleaning liquid to be continuously recycled, and increase water separator. Semi-washed cleaning effect is usually very good, but higher operating costs, recovery of waste can not be recycled, reused, including COD (chemical oxygen demand) is higher, the need for wastewater treatment. Brominated hydrocarbon solvent in recent years. In the United States, Japan and bromine-based cleaning agent available. And in the electronics industry, the aviation industry. Automotive Industry hood cleaners, household appliances widely used. Bromine-containing cleaning agent is the main component of high purity n-propyl bromide (NPB). Its performance with CFC-113 and TCA comparable. The main technical parameters and TCA is almost exactly the same, better wetting coefficient for metal parts cleaning ability. No flash point, can be repeatedly recycled use, low running costs. Replace CFC and TCA cleaners, exactly the same process, almost no need to replace equipment. Only need to adjust the temperature of steam cleaning can be, and is also known as the "Third World alternative cleaning agents." Bromine-containing cleaning agents ODP 0.006, lifetime in the atmosphere for 11 days, almost no GWP value. There are debates about the toxicity, United Nations Environment Programme (UNEP) has organized more than five years conducted experiments. Experimental results and theoretical analysis are very different. EPA policy March 27, 2002 released explicitly accept NPB as a solvent for cleaning, aerosol and adhesives. However, because there is no exact data on its toxicity, in use should be controlled in the air exposure concentrations.
