Simulate acid rain in Q-Sun Xenon Test Chamber.


Q-Lab Corporation, formerly Q-Panel Lab Products, has introduced the Q-Sun Xe-3-HDS Xenon xenon (zē`nŏn) [Gr.,=strange], gaseous chemical element; symbol Xe; at. no. 54; at. wt. 131.29; m.p. −111.9°C;; b.p. −107.1°C;; density 5.86 grams per liter at STP; valence usually 0.  Test Chamber, which features dual spray, allowing water and one separate solution to be sprayed onto test specimens. The Q-Sun is used to simulate and accelerate the synergistic effects Synergistic effect

A violation of value-additivity in that the value of a combination is greater than the sum of the individual values.
 of sunlight, heat, and moisture. With dual spray, an additional environmental factor can be added to this equation--acid rain, for example.

Acid rain is a problem that has plagued the automotive industry The automotive industry is the industry involved in the design, development, manufacture, marketing, and sale of motor vehicles. In 2006, more than 69 million motor vehicles, including cars and commercial vehicles were produced worldwide.  since the introduction of clearcoat systems in the 1980s. The new patent pending Q-Sun Xe-3-HDS was developed by Q-Lab through the accelerated acid etch To create a design in a material by digging out the material. The circuit designs on printed circuit boards and chips are etched by acid.

. The result of this research, the BASF/Q-Sun Acid Test, is reported to be the only acid etch test for clearcoats supported by years of research, data, and proven correlation. Using the Q-Sun Xe-3-HDS, etching similar to 14 weeks of outdoor exposure in Jacksonville, FL was produced in as little as 400 hr of laboratory testing. As shown in the graph, the BASF/Q-Sun Acid Test demonstrates excellent correlation to Jacksonville.

To develop this method, BASF researchers conducted several years of outdoor exposures to establish base line data. These exposures were at Blout Island (Jack-sonville), the internationally recognized benchmark location for acid rain. Researchers then formulated a special acid solution based on collected samples of Jacksonville's acid rain.

One of the critical factors used in the selection of the Q-Sun Xenon Test Chamber by BASF was Q-Sun's near-horizontal mounting system, which allows moisture to remain upon the specimens for a slow, controlled dry-off. For acid etch testing, this design feature has proven superior to rotating-drum style testers, which do not allow a solution to sit on a specimen for a long enough period of time.

When developing the Q-Sun Xe-3-HDS for this project, Q-Lab's design engineers made modifications to improve correlation and ease of use: additional spray nozzles A spray nozzle is a device that facilitates the formation of spray. When a liquid is dispersed as a stream of droplets (atomization), it is called a spray. The typical purpose of the spray is to maximize the effect of the liquid by increasing the total surface area for better  for the secondary solution; a self-contained unit with pump and 220-liter reservoir for ease of mobility; and an updated control system. As with all Q-Suns, the dual spray model uses full-spectrum xenon arc lamps Xenon arc lamps are an artificial light source. Powered by electricity, they use ionized xenon gas to produce a bright white light that closely mimics natural daylight.

Xenon arc lamps can be roughly divided into three categories:
 to reproduce the damaging effects of both short and long wavelengths of sunlight. The flat specimen tray provides flexible specimen mounting and can accommodate three-dimensional parts or components.

The BASF Acid Test is the first test procedure developed specifically for the Q-Sun Xe-3-HDS, but it will not be the last. The dual spray system can expand testing options by allowing users to create a more realistic exposure environment and test different formulations of products. Other existing standardized solutions (Chem.) a solution which is used as a reagent, and is of a known and standard strength; specifically, a normal solution, containing in each cubic centimeter as many milligrams of the element in question as the number representing its atomic weight; thus, a normal solution of silver , including soapy water, could serve a good starting point Noun 1. starting point - earliest limiting point

With the Q-Sun Xe-3-HDS, an effective light stability test procedure can be developed to reproduce the damage caused by sunlight, heat, and moisture in specific niche environments. For more details, contact: 440.835.8700 or www.q-sun.com.
