Chemical mixing, replenishment, and waste management system
A chemical control system for controlling the chemistry of a chemical solution having predetermined chemical constituents in a plating system, such as a NiFe plating system, employs a mix container for containing a plating solution and a hold container for containing a plating solution delivered from the mix container. A precision delivery arrangement delivers a precise predetermined quantum of a predetermined constituent of the plating solution to multiple mix containers and the hold containers. Transfer of plating solution between the mix and hold containers is effected by a transfer pump. Nitrogen gas that has been humidified with deionized water protects the plating solution from either acquiring water or becoming dehydrated, the humidified nitrogen gas being humidified to a predetermined relative humidity with respect to the temperature of the plating solution in the mix container. This is achieved by urging the nitrogen gas through a column that is at the same temperature as the plating solution. Precise delivery of the chemical constituents is achieved by a pneumatic pump arranged serially with an orifice and an inexpensive flow meter. The pneumatic pump is a positive displacement, double diaphragm pump.

The first method uses these bases to effectively redistribute the silicon-oxygen skeleton structure in the polymerized silsesquioxane [RSiO1.5]∞ to become a POSS nanostructure, that is, the formula [(RSiO1.5)n]∑ Homoleptic fragments represented by #, functionalized homoleptic fragments represented by [(RXSiO1.5)n]∑#, hybrid compounds represented by [(RSiO1.5)m(R'SiO1.5)n]∑# fragments (heteroleptic) and functionalized heterosegment nanostructures represented by {(RSiO1.5)m(RXSiO1.0)n}∑#, where ∞=1-1,000,000 or higher. The second method uses a base to help form POSS nanostructures from the silane RSiX3 and the linear or cyclic silsesquioxane represented by the formula RX2Si-(OSiRX)m-OSiRX2, that is, the formula [(RSiO1.5)n ]∑#, the homogeneous fragments shown and the miscellaneous fragments shown in [(RSiO1.5)m(R'SiO1.5)n]∑# and the heterogeneous fragments shown in [(RSiO1.5)m(RXSiO1.0)n]∑# Functionalized heterosegment nanostructure, where m=0-10, X=OH, Cl, Br, I, alkoxide OR, acetate OOCR, peroxide OOR, amine NR2, isocyanate NCO and R. The third method uses alkali to selectively open the silicon-oxygen-silicon (Si-O-Si) bonds in the POSS structure to form POSS species with incompletely condensed nanostructures. These methods also provide stereochemical control of X. These three methods can generate new POSS species, which can ultimately be transformed into POSS species suitable for polymerization, grafting, or other desired chemical reactions through additional chemical control.
