Grain effect

Arsenic added ia amounts of 0.1—3% improves the properties of lead-base babbitt alloys used for beatings (see Bearing materials). Arsenic (up to 0.75%), has been added to type metal to increase hardness and castabiUty (21). Addition of arsenic (0.1%) produces a desirable fine-grain effect in electrotype metal without appreciably affecting the hardness or ductihty. Arsenic (0.5—2%) improves the sphericity of lead ammunition. Automotive body solder of the composition 92% Pb, 5.0% Sb, and 2.5% Sn, contains 0.50% arsenic (see Solders and brazing alloys).

Cold Springs Station, Nevada, 1999. 2008 Steve Anchell. Ilford HP5+ developed in Edwal s FG-7 for 12 minutes at 70F/21C. The smooth tones of the fine grain effect are enhanced by the use of a medium format negative. Photo made with Mamiya RZ67 with a 65 mm f/4 lens. 

NOTE 1 This formula results in at least a one stop loss in speed. By increasing the glycin to as much as 12.0 grams, film sensitivity can be increased, but the fine-grain effect decreases. 

If the fine-grain effect is found to be too great and dichroic fog results, the sulfite content can be lowered. Alternatively, the amount of boric acid could be reduced, the borax increased, or both. Development times would be shorter. 

If an even finer-grained effect is desired, with an inevitable loss in film speed, increase the acid and extend the development time. This would also increase the chance of dichroic fog.

Monometallic catalysts on alumina supports are ideal cases for X-ray fluorescence analysis the matrix (alumina or alumina containing approximately 2% weight chlorine) remains " constant in terms of the matrix effects, and analysis can be conducted directly on finely crushed powder. Texture or grain effects must, however, be carefully avoided by using, in the preparation of standards, the same support as that of the catalysts. Any change in the nature of the support (granulometry, structural modifications, etc.) should be systematically indicated by the person requesting the analysis. 

Printed - (35%) surfaces are decorative pattern or simulated wood grain effects created by the application of liquid applied basecoats, inks and protective topcoats to lauan or other tropical hardwoods.

Wood-grain effects colorants for wood-plastic composites have been commercialized, with recently improved formulations reported by Americhem. These formulations are said to produce deep wood-grain effects for more naturallooking building products, serving as a durable low-cost altemahve to surface embossed graining or laminated films [9-39]. 

Basically, a large filler surface is desirable, but if it is too large it may result in agglomeration and will have a coarse-grained effect. 

In polymer blends technology it has been know that useful properties of mixed resins can be obtained without a need for compatibilization when the components are nearly miscible with each other [viz. several members of PO family, blends of PS with styrenic copolymers, etc.] and concentration of the minor-phase polymer does not exceed 15 wt%. Similarly, immiscible polymer blends also do not require compatibilization if the dispersed phase resin does not exceed 10 vol%. Blends having co-continuous morphology may also offer good performance with limited if any compatibilization. Materials developed for the esthetic, not structural reasons, viz. compositions showing nacreous or wood-grain effects, also may require little compatibilization.
