Water-based rinse system

The main application technique in the decorative area is still by hand (brush). Hence, future trends continue to reflect attention on worker exposure and environmental issues. This is already seen in the move to low aromatic content white spirits and isoparaffin solvents in conventional systems. High solids and waterborne technologies are being developed and both possess certain advantages and disadvantages, mainly relating to appearance and ease of use. Water-based systems bring, in principle, increased potential for water pollution, as consumers continue to rinse their brushes and paint rollers under the tap and transfer the water-soluble components such as amines and biocides to the aqueous environment. The consequence of diffuse water emissions of this type is still under debate.

The quality observed with "Mannich" derivatives of polyvinylphenol is affected by the concentration, time of treatment, temperature, pH, and whether or not a final deionized water rinse is used. The results shown in Tables I-III below represent evaluations conducted for poly-[methy1(2-hydroxyethy1)amino]methyl-4-vinylphenol, as shown in Structure I. Post-treatments based on polyvinylphenols overcome deficiencies observed with previous chrome-free rinses, since these systems are reactive and a final water rinse actually improves performance as is illustrated in Table I where the new non-chrome system is evaluated on Bonderite 1000, an iron phosphate conversion coating, as a function of concentration with and without a final water rinse. It is also... 

All operators were trained in the site operations based on the U.S. EPA "Operation and Maintenance Manual for Precipitation Measurement Systems" (6) and the UAPSP "Field Operator Instruction Manual" (7). Daily site visits were generally made at about 9 00 a.m. local time to check the equipment and to remove any precipitation collected by the daily samplers. Weekly samples were removed on Monday from the Georgia and Vermont sites and on Tuesday at the Kansas site. If no event occurred for a week, the buckets were rinsed with deionized water to remove any dust that may have deposited and they were then reused. Analysis of the rinse water served as a dynamic blank. 

Their base membranes of P(AN-co-AA) and P(AN-co-EDAMA) were ptrejjared by phase-inversion of their respective dimethyl sulfoxide solutions in water. I20 The base membranes of P(AN-co-AA) or P(AN-co-EDAMA) were orderly dipped in positive CTAC and negative PAA aqueous solutions. After each deposition step, the resulting membranes were rinsed thoroughly with water. Such deposition process was repeated to obtain desired number of self-assembled layers. In this research, P(AN-co-AA) or P(AN-co-EDAMA) membranes with ESA layers are referred to as P(AN-co-AA)/CTAC/PAA system or as P(AN-co-EDAMA)/PAA/CTAC system, respectively.
