Paint supply systems, design

In order to achieve maximum paint utilization, special electrostatic, high-rotation (HR) sprays are increasingly being examined for their specific apphcation potential, which in combination with the (highly conductive) waterborne paint systems also has a particular effect on the design of the entire paint supply system. The use of HR sprays for jpplying the basecoat is also being advanced... 

The bomb is then placed in the jacket, and the gas inlet tube is fastened securely. The thermocouple is also inserted. From this point on, all operations should be performed on the other side of the wall separating the operator from the equipment. Hydrogen is bled into the bomb from the high-pressure tank, the valve to the tank is closed, and the bomb is allowed to stand for about a half hour in order to test for leaks. If a leak has developed, as indicated by a drop in pressure, one locates it by painting all the joints with a soap solution and looking for bubbles of gas, which indicate a leak. The connector is tightened, and if this does not stop the leak, the pressure in the system should be released, the connection disassembled, and the tapered end of the tube re-formed with a tool supplied for the purpose. These measures usually will stop the leak, but if they do not, it will be necessary to ream out the connector seat with the reamer designed for this purpose. 

To clearly understand the relative importance of this element in the system safety order of precedence, consider the following example. An entrepreneur wishes to establish a small manufacturing facility that will be involved in the production of school desks. Part of the finishing process will require the application of several coats of lacquer to each desk surface. An enamel-based paint will also be used on the understructure of each desk. The facility will have only one small open-faced paint booth. Ventilation will be provided, and the operator will be supplied with respiratory protection in the form of disposable respirators. However, during the design phase, a system safety evaluation of the painting process required the identification... 

TROYSAN 174 is a non-meta11ic, organic biocide designed for use in systems which are subject to bacterial deterioration. Examples of such systems are latex paints, resin emulsions, adhesives, pigment dispersions, joint cements, cutting oils, drilling additives and any other system where water is a primary component. It is supplied as a clear amber water-soluble liquid. TROYSAN 174 is a broad spectrum biocide.
