This study investigates a new concept of producing precipitated calcium carbonate (PCC) from steelmaking slag and carbon dioxide via a spray carbonation process. The presented laboratory-scale spray carbonation test reactor uses a spray nozzle to disperse fine droplets of a Ca-rich solution into a spray tower, where calcium carbonate precipitates as a result of the reaction between calcium and ...

I N T R O D U C T I O N Mechanical and metallurgical requirements impose limits on the rates at which aluminum alloys can be quenched by water sprays. The upper limit is set by the occurrence of plastic deformation which causes warping of the product and the lower limit is set by an inability to develop the required metallurgical properties in subsequent heat treatment operations. In addition, ...

the spray characteristics of the fuel greatly influence emissions from diesel engines. spray development plays a vital role in improving the combustion and emission characteristics of fuel because it directly affects the air- fuel mixture formation. the spray characteristics of fuel mainly depend on fuel injection process, fuel density, fuel viscosity, ambient pressure and temperature. among th...

Wall painting is a repetitive, stressful, and hazardous process that makes it an ideal automation case. In the automotive industry, had been automated but not yet for construction industry. However, there strong need mobile robot can move to paint residential interior walls. this study, we aim design implement automatic robot. The conceptual of proposed wall consisting mechanism with spray gun ...

We evaluated the applicability of metal spray coating as a waterproofing/corrosion protection method for a concrete structure used for water purification. We carried out an ozone resistance test on four metal sprays and evaluated the water permeability and bond strength of the metals with superior ozone resistance, depending on the surface treatment method. In the ozone resistance test, four me...

While paint systems have been around for a long time, systems capable of capturing the complex behavior of paint media like watercolor, gouache, Oriental ink, oil and acrylic paint have emerged only recently. However, concentrating on the simulation of paint and brush mechanics, these applications mostly provide just a minimal set of instruments assisting users in creating artwork. We report on...

BACKGROUND We report a case of a spray painter who developed malignant fibrous histiocytoma (MFH) of the maxillary sinus following long-term exposure to chromium, nickel, and formaldehyde, implying that these agents are probable causal agents of MFH. CASE REPORT The patient developed right-sided prosopalgia that began twenty months ago. The symptom persisted despite medical treatment. After t...
