Humidity-resistant inorganic binder for sand core making in foundry practice

Ocular effects of exposure to triethylamine in the sand core cold box of a foundry.

OBJECTIVES To assess the acute and chronic ophthalmological effects of triethylamine exposure among foundry workers. METHODS Ocular effects on people currently, previously, and never exposed to triethylamine in a foundry cold box were studied at two points in time. The initial phase included an ocular examination with a slit lamp to assess corneal health, a visual acuity test, and a questionn...

User Guideline for Foundry Sand in Green Infrastructure Construction

Geoenvironmental behavior of foundry sand amended mixtures for highway subbases.

The high cost of landfilling and the potential uses of waste foundry sands have prompted research into their beneficial reuse. Roadways have a high potential for large volume usage of the foundry sands. A laboratory testing program was conducted on soil-foundry sand mixtures amended with cement and lime to assess their applicability as highway subbase materials. The mixtures were compacted in t...

A Humidity Sensing Organic-Inorganic Composite for Environmental Monitoring

In this paper, we present the effect of varying humidity levels on the electrical parameters and the multi frequency response of the electrical parameters of an organic-inorganic composite (PEPC+NiPc+Cu2O)-based humidity sensor. Silver thin films (thickness ~200 nm) were primarily deposited on plasma cleaned glass substrates by the physical vapor deposition (PVD) technique. A pair of rectangula...
