Title Smoke Material Process of zinc-coated calcium carbonate powder formed by electroless plating method.
Abstract
Electroless planting is one of the method to prepare metal-coated non-metallic composite powder, whose advantage is that any substrate such as glass, ceramics, plastic or metal surface can be prepared a uniform metal coating. It is based on a principle that self-catalytic oxidation-reduction reaction can be controlled in aqueous solution. This method does not require the applied current, and there is no restriction on the shape and type of substrate.
This essay studied plated coating powder particles principle, on a basis of calcium carbonate powder galvanizing technology, material preparation and application of smoke forming perceptual, and tested measurement, had a research on cold smoke smokescreen masking material terms Applications.
The main contents of this paper include calcium carbonate powder chemical galvanizing theoretical research, technology research and performance testing of composite materials.
Keywords electroless planting calcium carbonate smoke screening
